Energy Conservation Program for Consumer Products: Test 
Procedures for Residential Dishwashers, Dehumidifiers, and Conventional 
Cooking Products (Standby Mode and Off Mode)

AGENCY: Office of Energy Efficiency and Renewable Energy, Department of 
Energy.

ACTION: Notice of proposed rulemaking and announcement of public 
meeting.

-----------------------------------------------------------------------

SUMMARY: In order to implement recent amendments to the Energy Policy 
and Conservation Act of 1975 (EPCA), the U.S. Department of Energy 
(DOE) proposes to amend its test procedures for residential 
dishwashers, dehumidifiers, and conventional cooking products (which 
include cooktops, ovens, and ranges) to provide for measurement of 
standby mode and off mode energy use by these products. The proposed 
amendments would incorporate into the DOE test procedures relevant 
provisions from the International Electrotechnical Commission's (IEC) 
Standard 62301, ``Household electrical appliances--Measurement of 
standby power,'' First Edition 2005-06 (IEC Standard 62301 (First 
Edition)). DOE also proposes to adopt definitions of various modes of 
operation based on the relevant provisions from the IEC Standard 62301 
``Household electrical appliances--Measurement of standby power,'' 
Second Edition Final Draft International Standard (IEC Standard 62301 
(FDIS)). In addition, DOE proposes to adopt language to clarify 
application of these test procedure provisions for measuring standby 
mode and off mode power consumption in dishwashers, dehumidifiers, and 
conventional cooking products. Furthermore, the proposed amendments 
would add new calculations to determine annual energy consumption 
associated with the standby mode and off mode measured power. Finally, 
the amendments would modify existing energy consumption equations to 
integrate standby mode and off mode energy consumption into the 
calculation of overall annual energy consumption and annual operating 
cost of those products which already have definitions for such measures 
(dishwashers and conventional cooking products). DOE is also announcing 
a public meeting to discuss and receive comments on the issues 
presented in this notice.

DATES: Meeting: DOE will hold a public meeting on Friday, December 17, 
2010, from 9 a.m. to 4 p.m., in Washington, DC. DOE must receive 
requests to speak at the public meeting before 4 p.m., Friday, December 
3, 2010. DOE must receive a signed original and an electronic copy of 
statements to be given at the public meeting before 4 p.m., Friday, 
December 10, 2010.
    Comments: DOE will accept comments, data, and information regarding 
the notice of proposed rulemaking (NOPR) before and after the public 
meeting, but no later than February 15, 2011. For details, see section 
V, ``Public Participation,'' of this NOPR.

I. Background and Authority

    Title III, Part B of the Energy Policy and Conservation Act of 1975 
(EPCA), Public Law 94-163 (42 U.S.C. 6291-6309, as codified), 
established the ``Energy Conservation Program for Consumer Products 
Other Than Automobiles,'' a program covering most major household 
appliances, including residential dishwashers, conventional cooking 
products, and dehumidifiers,\1\ the subjects of today's notice.\2\ (42 
U.S.C. 6292(a)(6) and (10); 6295(cc)) Under the Act,\3\ this program 
consists essentially of three parts: (1) Testing; (2) labeling; and (3) 
Federal energy conservation standards.
---------------------------------------------------------------------------

    \1\ The term ``conventional cooking products,'' as used in this 
notice, refers to residential electric and gas kitchen ovens, 
ranges, and cooktops (other than microwave ovens).
    \2\ For editorial reasons, upon codification in the U.S. Code, 
Part B was re-designated as Part A.
    \3\ All references to EPCA refer to the statute as amended, 
including through the Energy Independence and Security Act of 2007, 
Public Law 110-140.
---------------------------------------------------------------------------

    Manufacturers of covered products must use DOE test procedures, 
prescribed under EPCA, to certify that their products comply with the 
energy conservation standards adopted under EPCA and to represent the 
energy consumption or energy efficiency of their products. (42 U.S.C. 
6293(c); 42 U.S.C. 6295(s)) DOE must also use DOE test procedures in 
any enforcement action to determine whether covered products comply 
with these energy conservation standards. (42 U.S.C. 6295(s)) Criteria 
and procedures for DOE's adoption and amendment of such test 
procedures, as set forth in EPCA, require that test procedures be 
reasonably designed to produce test results which measure energy 
efficiency, energy use, or estimated annual operating cost of a covered 
product during a representative average use cycle or period of use. 
Test procedures must also not be unduly burdensome to conduct. (42 
U.S.C. 6293(b)(3))
    If DOE determines that a test procedure amendment is warranted, it 
must publish proposed test procedures and offer the public an 
opportunity to present oral and written comments on them. (42 U.S.C. 
6293(b)(2)) In any rulemaking to amend a test procedure, DOE must 
determine to what extent, if any, the proposed test procedure would 
alter the measured energy efficiency of any covered product as 
determined under the existing test procedure. (42 U.S.C. 6293(e)(1)) If 
DOE determines that the amended test procedure would alter the measured 
efficiency of a covered product, DOE must amend the applicable energy 
conservation standard accordingly. (42 U.S.C. 6293(e)(2))

Dishwashers

    DOE's test procedure for dishwashers is found in the Code of 
Federal Regulations (CFR) at 10 CFR part 430, subpart B, appendix C. 
DOE originally established its test procedure for dishwashers in 1977. 
42 FR 39964 (August 8, 1977). Since that time, the dishwasher test 
procedure has undergone a number of amendments, as discussed below. In 
1983, DOE amended the test procedure to revise the representative 
average-use cycles to more accurately reflect consumer use and to 
address dishwashers that use 120 [deg]F inlet water. 48 FR 9202 (March 
3, 1983). DOE amended the test procedure again in 1984 to redefine the 
term ``water heating dishwasher.'' 49 FR 46533 (Nov. 27, 1984). In 
1987, DOE amended the test procedure to address models that use 50 
[deg]F inlet water. 52 FR 47549 (Dec. 15, 1987). In 2001, DOE revised 
the test procedure's testing specifications to improve testing 
repeatability, changed the definitions of ``compact dishwasher'' and 
``standard dishwasher,'' and reduced the average number of use cycles 
per year from 322 to 264. 66 FR 65091, 65095-97 (Dec. 18, 2001). In 
2003, DOE again revised the test procedure to more accurately measure 
dishwasher efficiency, energy use, and water use. The 2003 dishwasher 
test procedure amendments included the following revisions: (1) The 
addition of a method to rate the efficiency of soil-sensing products; 
(2) the addition of a method to measure standby power; and (3) a 
reduction in the average-use cycles per year from 264 to 215. 68 FR 
51887, 51899-903 (August 29, 2003). The current version of the test 
procedure includes provisions for determining estimated annual energy 
use (EAEU), estimated annual operating cost (EAOC), energy factor (EF) 
expressed in cycles per kilowatt-hour (kWh), and water consumption 
expressed in gallons per cycle. (10 CFR 430.23(c))
    The National Appliance Energy Conservation Act of 1987 (NAECA), 
Public Law 100-12, amended EPCA to establish prescriptive standards for 
dishwashers, requiring that dishwashers manufactured on or after 
January 1, 1988, be equipped with an option to dry without heat. (42 
U.S.C. 6295(g)(1)) These EPCA amendments also mandated that DOE must 
conduct two rounds of rulemaking to determine whether the energy 
conservation standards for dishwashers should be amended. (42 U.S.C. 
6295(g)(4)) On May 14, 1991, DOE issued a final rule establishing the 
first set of performance standards for dishwashers. 56 FR 22250. The 
final rule required that dishwashers manufactured on or after May 14, 
1994, must have a minimum EF of 0.46 cycles per kWh for standard size, 
and 0.62 cycles per kWh for compact size. Id. at 22279; 10 CFR 
430.32(f)(1).
    The Energy Independence and Security Act of 2007\4\ (EISA 2007) 
further amended EPCA, in relevant part by establishing the following 
energy conservation standards for residential dishwashers manufactured 
on or after January 1, 2010: (1) For standard size

[[Page 75292]]

dishwashers, a maximum annual energy use of 355 kWh per year, and a 
maximum water consumption of 6.5 gallons per cycle; and (2) for compact 
dishwashers, a maximum annual energy use of 260 kWh per year, and a 
maximum water consumption of 4.5 gallons per cycle. (42 U.S.C. 
6295(g)(10)(A); 10 CFR 430.32(f)(2)) The amendments also specify that 
not later than January 1, 2015, the Secretary shall publish a final 
rule determining whether to amend the standards for dishwashers 
manufactured on or after January 1, 2018. (42 U.S.C. 6295(g)(10)(B))
---------------------------------------------------------------------------

    \4\ Public Law. 110-140 (enacted Dec. 19, 2007).
---------------------------------------------------------------------------

Dehumidifiers

    The DOE test procedure for dehumidifiers is found at 10 CFR 430, 
subpart B, appendix X. The Energy Policy Act of 2005 (EPACT 2005), 
Public Law 109-58, amended EPCA to specify that the U.S. Environmental 
Protection Agency's (EPA) test criteria used under the ENERGY 
STAR[supreg] \5\ program must serve as the basis for the 
test procedure for dehumidifiers. (EPACT 2005, section 135(b); 42 
U.S.C. 6293(b)(13)) The ENERGY STAR test criteria require that American 
National Standards Institute (ANSI)/Association of Home Appliance 
Manufacturers (AHAM) Standard DH-1-2003, ``Dehumidifiers,'' be used to 
measure energy use and that the Canadian Standards Association (CAN/
CSA) standard CAN/CSA-C749-1994 (R2005), ``Performance of 
Dehumidifiers,'' be used to calculate EF. DOE has adopted these test 
criteria, along with related definitions and tolerances, as its test 
procedure for dehumidifiers. 71 FR 71340, 71347, 71366-68 (Dec. 8, 
2006). The DOE test procedure provides methods for determining the EF 
for dehumidifiers, which is expressed in liters (l) of water condensed 
per kWh.
---------------------------------------------------------------------------

    \5\ For more information on the ENERGY STAR program, see: http://www.energystar.gov.
---------------------------------------------------------------------------

    Section 135(c)(4) of EPACT 2005 added dehumidifiers as products 
covered under EPCA and established standards effective for 
dehumidifiers manufactured on or after October 1, 2007. (42 U.S.C. 
6295(cc)(1)) Section 311 of EISA 2007 further amended EPCA to revise 
the energy conservation standards for dehumidifiers, establishing the 
following minimum EFs based on product capacity for dehumidifiers 
manufactured on or after October 1, 2012:

Conventional Cooking Products

    DOE's test procedures for conventional ranges, cooktops, and ovens 
(including microwave ovens) are found at 10 CFR 430, subpart B, 
appendix I. DOE first established the test procedures included in 
appendix I in a final rule published in the Federal Register on May 10, 
1978. 43 FR 20108, 20120-28. DOE revised its test procedure for cooking 
products to more accurately measure their efficiency and energy use, 
and published the revisions as a final rule in 1997. 62 FR 51976 (Oct. 
3, 1997). These test procedure amendments included: (1) A reduction in 
the annual useful cooking energy; (2) a reduction in the number of 
self-cleaning oven cycles per year; and (3) incorporation of portions 
of IEC Standard 705-1988, ``Methods for measuring the performance of 
microwave ovens for household and similar purposes,'' and Amendment 2-
1993 for the testing of microwave ovens. Id. The test procedure for 
conventional cooking products establishes provisions for determining 
EAOC, cooking efficiency (defined as the ratio of cooking energy output 
to cooking energy input), and EF (defined as the ratio of annual useful 
cooking energy output to total annual energy input). (10 CFR 430.23(i); 
10 CFR part 430 subpart B, appendix I) These provisions for 
conventional cooking products are not currently used for compliance 
with any energy conservation standards (because those standards 
currently involve design requirements), nor is there an EnergyGuide \6\ 
labeling program for cooking products.
---------------------------------------------------------------------------

    \6\ For more information on the EnergyGuide labeling program, 
see: http://www.access.gpo.gov/nara/cfr/waisidx_00/16cfr305_00.html.
---------------------------------------------------------------------------

    DOE has initiated a separate test procedure rulemaking to address 
standby mode and off mode power consumption for microwave ovens. This 
rulemaking was initiated separately in response to comments from 
interested parties on the advance notice of proposed rulemaking (ANOPR) 
for an earlier rulemaking concerning energy conservation standards for 
dishwashers, dehumidifiers, cooking products, and commercial clothes 
washers published on November 15, 2007 (hereafter referred to as the 
November 2007 ANOPR) (72 FR 64432), prior to the enactment of EISA 
2007. As discussed in the October 2008 test procedure NOPR, interested 
parties stated generally that DOE should amend the test procedures for 
all types of cooking products to allow for measurement of standby mode 
energy use in order to implement a standby power energy conservation 
standard. 73 FR 62034, 62043-44 (Oct. 17, 2008). However, DOE did not 
receive any specific data or inputs on standby power consumption in 
conventional cooking products. Also, at that time, interested parties 
did not submit any comments regarding DOE addressing new measures of 
standby mode and off mode energy use in the test procedures or energy 
conservation standards for the other products that were the subject of 
the November 2007 ANOPR (i.e., dishwashers and dehumidifiers.) Because 
DOE agreed with the comments supporting new measures of standby mode 
and off mode energy use for microwave ovens and the potential for early 
adoption of an energy conservation standard for microwave ovens 
addressing standby mode and off mode energy consumption, DOE published 
a NOPR proposing amendments to just the microwave oven test procedure 
for standby mode and off mode in the Federal Register on October 17, 
2008. 73 FR 62134. DOE subsequently published a supplemental notice of 
proposed rulemaking (SNOPR) in the Federal Register on this topic on 
July 22, 2010. 75 FR 42612. Consequently, DOE is proposing amendments 
to its cooking products test procedure for only conventional cooking 
products in today's NOPR.
    As with dishwashers, NAECA amended EPCA to establish prescriptive 
standards for cooking products. The NAECA amendments required gas 
ranges and ovens with an electrical supply cord manufactured on or 
after January 1, 1990, not to be equipped with a constant-burning pilot 
light. (42 U.S.C. 6295(h)(1)) Subsequently, DOE published a final rule 
in the Federal Register on April 8, 2009, amending the energy 
conservation standard for cooking products to require for products 
manufactured on or after April 9, 2012, that gas cooking products 
without an electrical supply cord shall not be equipped with a constant 
burning pilot light. 74 FR 16040, 16094.

[[Page 75293]]

Standby Mode and Off Mode

    Section 310 of EISA 2007 amended EPCA to require DOE to amend the 
test procedures for covered products to address standby mode and off 
mode energy consumption. Specifically, the amendments also require DOE 
to integrate standby mode and off mode energy consumption into the 
overall energy efficiency, energy consumption, or other energy 
descriptor for that product unless the current test procedures already 
fully account for such consumption. If integration is technically 
infeasible, DOE must prescribe a separate standby mode and off mode 
energy use test procedure, if technically feasible. (42 U.S.C. 
6295(gg)(2)(A)) Any such amendment must consider the most current 
versions of IEC Standards 62301, ``Household electrical appliances--
Measurement of standby power,'' and IEC Standard 62087, ``Methods of 
measurement for the power consumption of audio, video, and related 
equipment.'' Id. For residential dishwashers, dehumidifiers, and 
conventional cooking products (and microwave ovens), DOE must prescribe 
any such amendment to the test procedures by final rule no later than 
March 31, 2011. (42 U.S.C. 6295(gg)(2)(B)(vi)) Furthermore, EISA 2007 
also amended EPCA to direct DOE to incorporate standby mode and off 
mode energy use into any final rule establishing or revising an energy 
conservation standard for a covered product adopted after July 1, 2010. 
If it is not feasible to incorporate standby mode and off mode into a 
single amended or new standard, then the statute requires DOE to 
prescribe a separate standard to address standby mode and off mode 
energy consumption. (42 U.S.C. 6295(gg)(3))
    DOE notes that the IEC is in the process of developing a revised 
version of IEC Standard 62301, which was expected to be released by 
July 2009. This revision is expected to be significantly delayed until 
late 2010 at the earliest. In order to publish a final rule by March 
31, 2011, DOE is proceeding with an amended test procedure based on the 
current version of IEC Standard 62301 (First Edition). However, DOE is 
also considering the updated mode of operation definitions in the 
latest draft version of IEC Standard 62301, IEC Standard 62301 (FDIS). 
Although not formally adopted, DOE is evaluating the substance of those 
definitions, which are expected to be included in the final revised IEC 
Standard 62301 (Second Edition).
    DOE acknowledges that the current dishwasher test procedure already 
includes definitions and testing methods for measuring standby mode 
power consumption similar to the IEC Standard 62301 (First Edition) 
provisions, but it does not include definitions and testing methods for 
measuring multiple standby modes and off mode power consumption. 
However, in today's NOPR, for the reasons discussed in section III.B, 
DOE proposes amendments to the current dishwasher test procedure in 
order to fully account for standby mode and off mode power consumption. 
These amendments would take into consideration the most current 
versions of IEC Standards 62301 and 62087.
    The current DOE dehumidifier test procedure does not address energy 
use when the product is in standby mode and off mode. For this reason, 
in today's NOPR, DOE is proposing amendments to its dehumidifier test 
procedure to provide for the measurement of standby mode and off mode 
energy consumption.
    The current DOE conventional cooking products test procedure does 
not fully account for standby mode and off mode energy consumption. 
However, DOE notes that the test procedures, as currently drafted, do 
account for standby energy use in narrow cases. The DOE conventional 
cooking products test procedures include provisions for determining the 
annual energy consumption of a continuously-operating clock, as well as 
the standby energy use associated with a continuously-burning pilot 
light for gas cooking products. Otherwise, the test procedure does not 
address energy use in standby mode or off mode. For this reason, in 
today's NOPR, DOE proposes amendments to the conventional cooking 
products test procedures to fully account for standby mode and off mode 
power consumption.

II. Summary of the Proposal

    In today's NOPR, DOE proposes to amend the test procedures for 
dishwashers, dehumidifiers, and conventional cooking products in order 
to:
    (1) Provide a foundation for DOE to develop and implement standards 
that address use of standby mode and off mode power by these products; 
and
    (2) Address the statutory requirement to expand test procedures to 
incorporate measures of standby mode and off mode power consumption.
    In general, DOE proposes to incorporate by reference into the test 
procedures for these products specific provisions from IEC Standard 
62301 (First Edition) regarding test conditions and test procedures for 
measuring standby mode and off mode power consumption, and to include 
language that would clarify the application of such provisions. DOE 
also proposes to incorporate into each test procedure the definitions 
of ``active mode,'' ``standby mode,'' and ``off mode'' that are based 
on the definitions for those terms provided in IEC Standard 62301 
(FDIS). Further, DOE proposes to include in each test procedure 
additional language that would clarify the application of clauses from 
IEC Standard 62301 (First Edition) for measuring standby mode and off 
mode power consumption.\7\
---------------------------------------------------------------------------

    \7\ EISA 2007 directs DOE to also consider IEC Standard 62087 
when amending its test procedure to include standby mode and off 
mode energy consumption. See 42 U.S.C. 6295(gg)(2)(A). However, IEC 
Standard 62087 addresses the methods of measuring the power 
consumption of audio, video, and related equipment. As explained 
subsequently in this notice, the narrow scope of this particular IEC 
standard reduces its relevance to today's proposal.
---------------------------------------------------------------------------

    As an initial matter, DOE had to analyze a number of product-
specific modes in order to determine whether they should be 
characterized as active mode, standby mode, or off mode functions. As 
discussed in further detail below, this rulemaking is limited to 
addressing standby mode and off mode. Based upon the results of its 
analyses, DOE is proposing the following product-specific amendments to 
the applicable DOE test procedures. For dishwashers, DOE is proposing 
definitions for the following different standby modes: (1) A general 
``inactive'' mode; and (2) a ``cycle finished'' mode. For 
dehumidifiers, DOE is proposing definitions for the following different 
standby modes: (1) a general ``inactive'' mode; (2) an ``off-cycle'' 
mode; and (3) a ``bucket full/removed'' mode. For conventional cooking 
products, DOE is also proposing definitions for the following different 
standby modes: (1) A general ``inactive'' mode; and (2) a ``cycle 
finished'' mode. For each product, energy use in each standby mode, as 
well as energy use in the off mode, would be separately tested under 
the appropriate procedure and incorporated into an integrated energy 
efficiency metric for that product.
    The current DOE dishwasher test procedure already includes 
provisions for measuring standby power and includes it in the EAEU and 
EAOC calculations. However, as discussed earlier, DOE is proposing 
amendments to the dishwasher test procedure, pursuant to EPCA, to fully 
and more accurately account for standby mode and off mode power 
consumption based on provisions in IEC Standard 62301. As a result, DOE 
is proposing revisions to the EAEU and EAOC calculations to

[[Page 75294]]

incorporate the revised measurements of standby mode and off mode power 
consumption into the combined metrics for dishwashers.
    For dehumidifiers, DOE is proposing in today's NOPR to:
    (1) Establish a new measure of energy use to calculate the annual 
standby mode and off mode energy use in dehumidifiers, based on the 
typical hours dehumidifiers spend in these modes; and
    (2) Adopt a new measure of energy efficiency (integrated energy 
factor (IEF)) that includes energy used in standby, off, and active 
modes for dehumidifiers.
    For conventional cooking products, the current DOE test procedure 
accounts for energy used by a constant clock display (if present), 
which is considered as part of standby mode under the proposed 
definition of ``standby mode.'' The current test procedure also 
accounts for standby mode energy use of a continuously-burning pilot 
light for gas conventional cooking products.\8\ However, DOE proposes 
in today's NOPR to amend the test procedure for conventional cooking 
products to fully account for all additional standby mode and off mode 
power consumption, as specified by provisions in IEC Standard 62301. 
DOE proposes in today's NOPR to: (1) Establish a new measure of energy 
use to calculate the annual standby mode and off mode energy 
consumption in conventional cooking products, and (2) adopt new 
measures of energy efficiency (IEF), annual energy consumption, and 
annual operating cost that include the energy used in all standby mode 
and off mode operations of conventional cooking products. In addition, 
DOE proposes additional clarifications to the testing methods for 
conventional cooking products to define the test duration for cases in 
which the measured power is not stable (i.e., varies over a cycle). DOE 
acknowledges that the power consumption of conventional cooking product 
displays can vary based on the clock time being displayed, so today's 
proposal is drafted in a way to account for this fact, while still 
generating representative results.
---------------------------------------------------------------------------

    \8\ DOE notes that it published a final rule in the Federal 
Register on April 8, 2009, establishing standards that prohibit 
continuously-burning pilot lights for gas cooking products 
manufactured on or after April 9, 2012. 74 FR 16040, 16094.
---------------------------------------------------------------------------

    The statute also has other provisions regarding the inclusion of 
standby mode and off mode energy use in any energy conservation 
standard which have bearing on the current test procedure rulemaking. 
EPCA provides that amendments to the test procedures to include standby 
mode and off mode energy consumption shall not be used to determine 
compliance with product standards established prior to the adoption of 
the amended test procedures. (42 U.S.C. 6295(gg)(2)(C)) However, EPCA 
requires that DOE must determine to what extent, if any, the proposed 
test procedure would alter the measured energy efficiency, measured 
energy use, or measured water use of any covered product as determined 
under the existing test procedure. (42 U.S.C. 6293(e)(1)) If DOE 
determines that the amended test procedure would alter the measured 
efficiency or measured energy use of a covered product, DOE must amend 
the applicable energy conservation standard during the rulemaking 
carried out with respect to the amended test procedure. In determining 
the amended energy conservation standard, the Secretary shall measure, 
pursuant to the amended test procedure, the energy efficiency, energy 
use, or water use of a representative sample of covered products that 
minimally comply with the existing standard. (42 U.S.C. 6293(e)(2)) 
Although DOE remains obligated under 42 U.S.C. 6293(e)(1) to conduct an 
analysis of the impact of the test procedure amendments, amendments to 
the existing energy conservation standards are not required, because 
the statute already explicitly provides that the test procedure 
amendments for standby mode and off mode shall not apply to the energy 
conservation standards currently in place. The following discussion 
assesses these anticipated impacts, as well as the pathway for 
regulated entities to continue to be able to ascertain, certify, and 
report compliance with the existing standards until such time as 
amended standards are established which comprehensively address standby 
mode and off mode energy consumption.
    For dishwashers, the current energy conservation standards (10 CFR 
430.32(f)) are based on EAEU, which includes a simplified measure of 
standby mode power consumption. Because today's proposed amendments 
would revise the calculations for EAEU and EAOC, both of which 
currently incorporate standby mode power, DOE investigated how the 
proposed amendments would affect the measured efficiency. As discussed 
in section III.G, DOE has tentatively determined that the proposed 
amendments in today's NOPR would not measurably alter the measured 
efficiency of dishwashers. In addition, the proposed amendments would 
clarify that the amended calculations for EAEU need not be performed to 
demonstrate compliance with the existing energy conservation standards 
until the compliance date of amended energy conservation standards for 
dishwashers which take into account standby mode and off mode energy 
use. The proposed amendments would also require that any 
representations as to standby mode and off mode energy use must use the 
amended calculations for EAEU and EAOC on or after a date 180 days 
after publication of the test procedure final rule. The amended test 
procedure, therefore, would still be able to be used by manufacturers 
to certify compliance of existing dishwashers with the current energy 
conservation standards.
    The current Federal energy conservation standards for dehumidifiers 
(10 CFR 430.32(v)), which are based on EF, do not currently account for 
standby mode or off mode power consumption. DOE proposes to establish a 
new integrated efficiency metric (integrated annual energy use) to 
account for standby mode and off mode power consumption. For this 
reason, the proposed amended test procedure would not alter the 
existing energy efficiency descriptor and, therefore, would not affect 
a manufacturer's ability to demonstrate compliance with previously 
established standards for dehumidifiers.
    As noted earlier, the current energy conservation standards for 
cooking products (10 CFR 430.32(j)) require only that gas cooking 
products with an electrical supply cord not be equipped with a 
constant-burning pilot light. The same requirement applies to gas 
cooking products without an electrical supply cord, beginning on April 
9, 2012. There are currently no performance-based Federal energy 
conservation standards for conventional cooking products (including 
energy use in standby mode and off mode). Thus, given the design 
standard currently in place, the proposed test procedure amendments 
would not alter one's ability to comply with the existing energy 
conservation standard for cooking products.
    These amended test procedures would become effective in terms of 
adoption into the CFR, 30 days after the test procedure final rule is 
published in the Federal Register. However, DOE is proposing added 
language to the regulations codified in the CFR that would state that 
any added procedures and calculations for standby mode and off mode 
energy consumption resulting from implementation of the relevant 
provisions of EISA 2007 need not be performed at this time to determine 
compliance with the current energy conservation standards. 
Subsequently, manufacturers would be required to use

[[Page 75295]]

the amended test procedures' standby mode and off mode provisions to 
demonstrate compliance with DOE's energy conservation standards on the 
mandatory compliance date of a final rule establishing amended energy 
conservation standards for dishwasher, dehumidifier, and conventional 
cooking products that address standby mode and off mode energy 
consumption, at which time the limiting statements in the DOE test 
procedures would be removed. Further clarification would also be 
provided that as of 180 days after publication of a test procedure 
final rule, any representations related to the standby mode and off 
mode energy consumption of these products must be based upon results 
generated under the applicable provision of these test procedures. (42 
U.S.C. 6293(c)(2))
    As noted above, pursuant to its statutory mandate under 42 U.S.C. 
6295(gg)(2), DOE is only addressing issues related to standby mode and 
off mode energy use in the current test procedure rulemaking for 
residential dishwashers, dehumidifiers, and conventional cooking 
products. For issues that are determined to relate to active mode 
energy use for any of these products, DOE will consider such amendments 
in a future test procedure rulemaking under section 302 of EISA 2007. 
Specifically, under that provision, DOE is required to review test 
procedures for covered products not later than every 7 years and to 
determine whether the test procedures accurately and fully comply with 
the requirement that they produce test results which are representative 
and not unduly burdensome to conduct. (42 U.S.C. 6293(b)(1))

III. Discussion

A. Products Covered by the Proposed Test Procedure Amendments

    Today's proposed amendments to the DOE test procedures cover 
dishwashers, which DOE defines as follows:

    ``Dishwasher means a cabinet-like appliance which with the aid 
of water and detergent, washes, rinses, and dries (when a drying 
process is included) dishware, glassware, eating utensils, and most 
cooking utensils by chemical, mechanical and/or electrical means and 
discharges to the plumbing drainage system.'' 10 CFR 430.2.

    Today's proposed amendments to the DOE test procedures also cover 
dehumidifiers, which DOE defines as follows:

    ``Dehumidifier means a self-contained, electrically operated, 
and mechanically refrigerated encased assembly consisting of--
    (1) A refrigerated surface (evaporator) that condenses moisture 
from the atmosphere;
    (2) A refrigerating system, including an electric motor;
    (3) An air-circulating fan; and
    (4) Means for collecting or disposing of the condensate.''

Id.
    Today's proposed amendments to the DOE test procedures also cover 
cooking products, specifically conventional cooking products, which are 
defined as:

    ``Cooking products means consumer products that are used as the 
major household cooking appliances. They are designed to cook or 
heat different types of food by one or more of the following sources 
of heat: Gas, electricity, or microwave energy. Each product may 
consist of a horizontal cooking top containing one or more surface 
units and/or one or more heating compartments. They must be one of 
the following classes: Conventional ranges, conventional cooking 
tops, conventional ovens, microwave ovens, microwave/conventional 
ranges and other cooking products.''
* * * * *
    ``Conventional cooking top means a class of kitchen ranges and 
ovens which is a household cooking appliance consisting of a 
horizontal surface containing one or more surface units which 
include either a gas flame or electric resistance heating.''
    ``Conventional oven means a class of kitchen ranges and ovens 
which is a household cooking appliance consisting of one or more 
compartments intended for the cooking or heating of food by means of 
either a gas flame or electric resistance heating. It does not 
include portable or countertop ovens which use electric resistance 
heating for the cooking or heating of food and are designed for an 
electrical supply of approximately 120 volts.''
    ``Conventional range means a class of kitchen ranges and ovens 
which is a household cooking appliance consisting of a conventional 
cooking top and one or more conventional ovens.''

Id.

    DOE is not proposing any amendments to these definitions in today's 
notice.

B. Incorporation by Reference of IEC Standard 62301 (First Edition) for 
Measuring Standby Mode and Off Mode Power Consumption

    As required by EPCA, as amended by EISA 2007, DOE considered the 
most current versions of IEC Standard 62301 and IEC Standard 62087 for 
measuring power consumption in standby mode and off mode when 
developing today's proposed amendments to the test procedures. (42 
U.S.C. 6295(gg)(2)(A)) DOE notes that IEC Standard 62301 includes 
provisions for measuring standby power in electrical appliances, and, 
thus, is relevant to this rulemaking. DOE also reviewed IEC Standard 
62087, which specifies methods of measuring the power consumption of TV 
receivers, video cassette recorders (VCRs), set top boxes, audio 
equipment, and multi-function equipment for consumer use. IEC Standard 
62087 does not, however, include methods for measuring the power 
consumption of electrical appliances such as dishwashers, 
dehumidifiers, or conventional cooking products. Therefore, DOE has 
tentatively determined that IEC Standard 62087 is unsuitable to this 
rulemaking and has not included any of its provisions in today's 
proposed test procedure amendments.
    DOE proposes to incorporate by reference into these test procedures 
specific clauses from IEC Standard 62301 (First Edition) for measuring 
standby mode and off mode power. Specifically, two clauses provide test 
conditions and test procedures for measuring the average standby mode 
and average off mode power consumption. Section 4 of IEC Standard 62301 
(First Edition) specifies test room conditions, supply voltage 
waveform, and power measurement meter tolerances, thereby ensuring 
repeatable and precise measurements of standby mode and off mode power 
consumption. Section 5 of IEC Standard 62301 (First Edition), regarding 
test procedures, specifies methods for measuring power consumption when 
it is stable and unstable (i.e., varies over a representative cycle).
    Specifically, DOE proposes to incorporate by reference into the DOE 
test procedures for dishwashers, dehumidifiers, and conventional 
cooking products the following provisions from IEC Standard 62301 
(First Edition):

                                         5.3 Procedure.
------------------------------------------------------------------------

    DOE notes that the current dishwasher test procedure already 
includes testing methods for measuring standby power consumption that 
are very similar to the provisions in IEC Standard 62301 (First 
Edition). However, DOE also notes that the current dishwasher test 
procedure does not contain provisions for measuring multiple standby 
modes or an off mode. EPCA, as amended by EISA 2007, requires DOE to 
amend its test procedures for all covered products to fully account for 
and incorporate standby mode and off mode energy consumption, and to 
consider the most current version of IEC Standard 62301 as it does so. 
(42 U.S.C. 6295(gg)(2)(A)) As discussed below, DOE proposes to amend 
the dishwasher test procedure to include new definitions of ``standby 
mode,'' ``off mode,'' and ``active mode'' based on the provisions in 
IEC Standard 62301 (FDIS). DOE also analyzed the current DOE dishwasher 
test procedure to determine if any other amendments would be necessary. 
The analysis has led DOE to tentatively conclude that the proposed 
clauses from IEC Standard 62301 (First Edition) presented earlier would 
clarify the dishwasher testing procedure, as well as produce 
representative and repeatable test results.
    As discussed in Section I, the current DOE conventional cooking 
products test procedure does not fully account for standby mode and off 
mode energy consumption. The test procedure accounts only for the 
annual energy consumption of a continuously-operating clock, and the 
standby energy use associated with a continuously-burning pilot light 
for gas cooking products. Otherwise, this test procedure does not 
address energy use in standby mode or off mode. For this reason, DOE 
has tentatively concluded that adopting the clauses from IEC Standard 
62301 (First Edition) as proposed would provide for a test procedure 
that would produce representative and repeatable test results that 
would fully account for standby mode and off mode energy consumption.
    As also discussed in section I, the current DOE dehumidifier test 
procedure does not contain any provisions for measuring energy use in 
standby mode or off mode. DOE has tentatively concluded that adopting 
the clauses from IEC Standard 62301 (First Edition) as proposed would 
provide for a test procedure that would produce representative and 
repeatable test results that would fully account for the standby mode 
and off mode energy consumption of dehumidifiers.
    DOE invites comment on whether IEC Standard 62301 (First Edition) 
can adequately measure standby mode and off mode power consumption for 
dishwashers, dehumidifiers, and conventional cooking products, and 
whether these specific provisions should be incorporated into the test 
procedures.
    DOE is aware that the EPCA requirement to consider IEC Standard 
62301 in developing amended test procedures to include standby mode and 
off mode power consumption results in a potential conflict between the 
EPCA and IEC Standard 62301 (FDIS) definitions of ``standby mode.'' 
EPCA defines ``standby mode'' as the condition in which a product is 
connected to a main power source and offers one or more of the 
following user-oriented or protective functions: (1) To facilitate the 
activation or deactivation of other functions (including active mode) 
by remote switch (including remote control), internal sensor, or timer; 
and/or (2) to provide continuous functions, including information or 
status displays (including clocks) or sensor-based functions. (42 
U.S.C. 6295(gg)(1)(A)(iii)) However, paragraph 3.1 of the IEC Standard 
62301 (First Edition) defines ``standby mode'' as the ``lowest power 
consumption mode which cannot be switched off (influenced) by the user 
and that may persist for an indefinite time when an appliance is 
connected to the main electricity supply and used in accordance with 
the manufacturer's instructions.'' Finally, DOE adopted a third 
definition prior to EISA 2007 for ``standby mode'' nearly identical to 
that of IEC Standard 62301 (First Edition) in the dishwasher test 
procedure, in which ``standby mode'' ``means the lowest power 
consumption mode which cannot be switched off or influenced by the user 
and that may persist for an indefinite time when the dishwasher is 
connected to the main electricity supply and used in accordance with 
the manufacturer's instructions.'' (10 CFR part 430, subpart B, 
appendix C, section 1.14) However, DOE is free to resolve any such 
conflict, because EISA 2007 specifically grants authority to amend the 
statutory definitions of ``active mode,'' ``off mode,'' and ``standby 
mode.'' (42 U.S.C. 6295(gg)(1)(B)) DOE notes that the statute requires 
consideration of the most current version of IEC Standard 62301, but it 
does not require its adoption if DOE determines that another 
definition(s) would be more appropriate.
    Although 42 U.S.C. 6295(gg)(2)(A) requires that DOE consider the 
most current version of IEC Standard 62301, DOE notes that the IEC is 
developing an updated version of this standard, IEC Standard 62301 
(Second Edition). This updated version of IEC Standard 62301 is 
expected to include definitions of ``off mode,'' ``network mode,'' and 
``disconnected mode,'' and it would also revise the current IEC 
Standard 62301 (First Edition) definition of ``standby mode.'' However, 
the IEC anticipates that the final version of IEC Standard 62301 
(Second Edition) will likely be published only in late 2010 at the 
earliest. Therefore, for this proposed rule, the second edition is not 
available for DOE's consideration or incorporation by reference. Thus, 
IEC Standard 62301 (First Edition) is the ``current version'' for 
purposes of 42 U.S.C. 6295(gg)(2)(A).
    DOE is aware that there are significant differences between IEC 
Standard 62301 (First Edition) and IEC Standard 62301 (FDIS), which is 
the latest draft version of IEC Standard 62301 (Second Edition). For 
example, IEC Standard 62301 (FDIS) clarifies certain provisions, such 
as clarifying the definition of ``standby mode'' and ``off mode'' to 
allow for the measurement of multiple standby power modes.
    DOE has reviewed IEC Standard 62301 (FDIS) and anticipates that, 
once finalized, it will ultimately define the

[[Page 75297]]

various modes differently than IEC Standard 62301 (First Edition). IEC 
Standard 62301 (FDIS) incorporates responses to comments from multiple 
national committees from member countries on several previous draft 
versions, and thus, DOE believes, it provides the best available mode 
definitions. Although the revised IEC Standard 62301 (Second Edition) 
has not yet been officially released, DOE has decided to consider the 
substance of the new operational mode definitions from the draft 
version IEC Standard 62301 (FDIS). DOE notes that the mode definitions 
in IEC Standard 62301 (FDIS) are substantively similar to those in the 
previous draft version (IEC Standard 62301 (CDV)), which were the 
subject of extensive comments from interested parties during recent DOE 
test procedure rulemakings addressing standby mode and off mode energy 
use in other products (i.e., microwave ovens, clothes dryers, and room 
air conditioners). In those instances, interested parties indicated 
general support for adopting the mode definitions provided in IEC 
Standard 62301 (CDV). Due to the effective equivalence of the mode 
definitions in IEC Standard 62301 (CDV) and IEC Standard 62301 (FDIS), 
DOE believes the public comment support expressed for the mode 
definitions in IEC Standard 62301 (CDV) would extend to those in IEC 
Standard 62301 (FDIS).
    DOE notes that other significant changes in the methodology were 
first introduced only at the IEC Standard 62301 (FDIS) stage. These 
changes have not been the subject of significant public comment from 
interested parties, nor has DOE had the opportunity to conduct a 
thorough analysis of those provisions. Consequently, the merits of 
these latest changes have not been fully vetted, as would demonstrate 
that they are preferable to the existing methodological provisions in 
the current version of the IEC standard. Thus, DOE is not able to 
determine whether the updated methodology represents the best available 
means to measure standby mode and off mode energy use, so DOE has 
tentatively decided to base the proposed test procedure amendments 
(other than the mode definitions previously discussed) on the 
provisions of IEC Standard 62301 (First Edition).
    After considering the most current version of IEC Standard 62301 
(i.e., the First Edition) and the draft version of IEC Standard 62301 
(i.e., FDIS), DOE has tentatively concluded that the definitions of 
``standby mode,'' ``off mode,'' and ``active mode'' provided in IEC 
Standard 62301 (FDIS) are the most useful, in that they expand upon the 
EPCA mode definitions and provide additional guidance as to which 
functions are associated with each mode. Therefore, DOE is proposing 
definitions of ``standby mode,'' ``off mode,'' and ``active mode'' 
based on the definitions provided in IEC Standard 62301 (FDIS). These 
definitions are discussed in detail immediately below in section III.C.

C. Determination and Classification of Operational Modes

    As stated earlier, without further clarification, regulated 
parties' attempts to reconcile differences between the mode definitions 
specified by EPCA and IEC Standard 62301 (First Edition) could lead to 
multiple interpretations. Therefore, DOE is proposing regulatory 
definitions for these key terms in order to ensure consistent 
application of the test procedure provisions related to standby mode 
and off mode. This section first discusses these overarching 
definitional changes and then follows with a product-specific analysis 
of different operational modes in order to determine whether they are 
active mode, standby mode, or off mode functions. DOE's proposed 
approach is set forth below.
    EPCA defines ``active mode'' as the condition in which an energy-
using product:
    (1) Is connected to a main power source;
    (2) Has been activated; and
    (3) Provides one or more main functions.

(42 U.S.C. 6295(gg)(1)(A)(i))

    EPCA defines ``standby mode'' as the condition in which an energy-
using product:
    (1) Is connected to a main power source; and
    (2) Offers one or more of the following user-oriented or protective 
functions:
    (a) To facilitate the activation or deactivation of other functions 
(including active mode) by remote switch (including remote control), 
internal sensor, or timer;
    (b) Continuous functions, including information or status displays 
(including clocks) or sensor-based functions.

(42 U.S.C. 6295(gg)(1)(A)(iii))

    This definition of ``standby mode'' differs from the one provided 
in IEC Standard 62301 (First Edition) by permitting the inclusion of 
multiple standby modes.
    EPCA defines ``off mode'' as the condition in which an energy-using 
product:
    (1) Is connected to a main power source; and
    (2) Is not providing any standby mode or active mode function.

(42 U.S.C. 6295(gg)(1)(A)(ii))

    DOE recognizes that the EPCA definitions for ``active mode,'' 
``standby mode,'' and ``off mode'' were developed to be broadly 
applicable for many energy-using products. For specific products with 
multiple functions, these broad definitions could lead to multiple 
interpretations. Therefore, DOE proposes to amend the test procedures 
to include definitions for these modes based on the definitions 
provided in IEC Standard 62301 (FDIS), with added provisions specific 
to dishwashers, dehumidifiers, and conventional cooking products. DOE's 
proposed approach is discussed below.
    DOE proposes to define ``active mode'' for dishwashers, 
dehumidifiers, and conventional cooking products as the condition in 
which the energy-using product is connected to a mains power source, 
has been activated, and provides one or more main functions. DOE notes 
that section 3.8 of IEC Standard 62301 (Second Edition Committee Draft 
2) (IEC Standard 62301 (CD2)) provides the additional clarification 
that ``delay start mode is a one off user initiated short duration 
function that is associated with an active mode.'' The subsequent IEC 
Standard 62301 Committee Draft for Vote (IEC Standard 62301 (CDV)) 
removed this clarification based on a comment from a member committee 
on IEC Standard 62301 (CD2) that the clarification conflicted with the 
proposed definition of ``standby mode,'' which would include 
``activation of * * * active mode by * * * timer.'' However, in its 
response to that comment, the IEC reiterated that delay start mode is a 
one-off function of limited duration, even though it took action to 
delete the clarification in IEC Standard 62301 (CDV).\9\ DOE infers 
this to mean that delay start mode should, therefore, be considered 
part of active mode. However, DOE notes that IEC Standard 62301 (FDIS) 
classifies delay start as a secondary function and not part of active 
mode. DOE continues to believe, however, that because delay start is of 
limited duration and is uniquely associated with the initiation of a 
main function, it should be considered part of active mode. Additional 
discussion of delay start mode is provided later in this section.

---------------------------------------------------------------------------

    DOE also proposes the following clarifications for the range of 
main

[[Page 75298]]

---------------------------------------------------------------------------
functions that would be classified as active mode for each product:

    Dishwashers--``Active mode'' means a mode in which the 
dishwasher is performing the main function of washing, rinsing, or 
drying (when a drying process is included) dishware, glassware, 
eating utensils, and most cooking utensils by chemical, mechanical 
and/or electrical means, or is involved in functions necessary for 
these main functions, such as admitting water into the dishwasher or 
pumping water out of the dishwasher.
    Conventional Cooking Products--``Active mode'' means a mode in 
which a conventional cooking top, conventional oven, or conventional 
range is performing the main function of cooking, heating, proofing, 
or holding the cooking load by means of either a gas flame or 
electric resistance heating.
    Dehumidifiers--``Active mode'' means a mode in which a 
dehumidifier is performing the main functions of removing moisture 
from ambient air by drawing moist air over a refrigerated coil using 
a fan, circulating air through activation of the fan without 
activation of the refrigeration system, or defrosting the 
refrigerant coil.

    DOE proposes to define ``standby mode'' for dishwashers, 
dehumidifiers, and conventional cooking products as any mode in which 
the product is connected to a mains power source and offers one or more 
of the following user-oriented or protective functions which may 
persist for an indefinite time: \10\
---------------------------------------------------------------------------

    \10\ The actual language for the ``standby mode'' definition in 
IEC Standard 62301 (FDIS) describes ``* * * user oriented or 
protective functions which usually persist'' rather than ``* * * 
user oriented or protective functions which may persist for an 
indefinite time.'' DOE notes, however, that section 5.1 of IEC 
Standard 62301 (FDIS) states that ``a mode is considered to be 
persistent where the power level is constant or where there are 
several power levels that occur in a regular sequence for an 
indefinite period of time.'' DOE believes that the proposed 
language, which was originally included in IEC Standard 62301 (CD2), 
encompasses the possible scenarios foreseen by section 5.1 of IEC 
Standard 62301 (FDIS) without unnecessary specificity.
---------------------------------------------------------------------------

     To facilitate the activation of other modes (including 
activation or deactivation of active mode) by remote switch (including 
remote control), internal sensor, or timer;
     Continuous functions, including information or status 
displays (including clocks) or sensor-based functions.
    DOE proposes the additional clarification that a timer is a 
continuous clock function (which may or may not be associated with a 
display) that provides regular scheduled tasks (e.g., switching) and 
that operates on a continuous basis. As noted in section III.B, this 
definition of ``standby mode'' is based on the definitions provided in 
IEC Standard 62301 (FDIS), and expands upon the EPCA mode definitions 
to provide additional clarifications as to which functions are 
associated with each mode.
    As noted earlier, the current DOE dishwasher test procedure defines 
``standby mode'' as the lowest power consumption mode that cannot be 
switched off or influenced by the user and that may persist for an 
indefinite time when the dishwasher is connected to the main 
electricity supply and used in accordance with manufacturer's 
instructions. That definition is comparable to the definition in IEC 
Standard 62301 (First Edition). DOE believes that the proposed 
``standby mode'' definition based on IEC Standard 62301 (FDIS) is 
preferable in that it expands upon the definition in IEC Standard 62301 
(First Edition) and provides additional guidance as to what functions 
are associated with standby mode. For this reason, DOE proposes in 
today's NOPR to amend the ``standby mode'' definition in the dishwasher 
test procedure based on the definition provided in IEC Standard 62301 
(FDIS). Furthermore, DOE proposes to redesignate the current DOE 
definition as a ``simplified standby mode'' in order to allow 
manufacturers to continue to use the existing standby mode provisions 
to determine compliance with the current dishwasher energy conservation 
standards until such time as these standards are amended to address 
standby mode and off mode energy use.
    DOE proposes to define ``inactive mode'' for dishwashers, 
dehumidifiers, and conventional cooking products as a standby mode that 
facilitates the activation of active mode by remote switch (including 
remote control), internal sensor, or timer, or that provides continuous 
status display.
    The following discussion analyzes various product-specific modes 
for dishwashers, dehumidifiers, and conventional cooking products to 
determine whether they would be properly characterized as active mode, 
standby mode, or off mode functions.
1. Dishwashers
    DOE is aware of two additional relevant modes for dishwashers: (1) 
delay start mode; and (2) cycle finished mode. ``Delay start mode'' is 
defined as a mode in which activation of an active mode is facilitated 
by a timer. ``Cycle finished mode'' is defined as a mode that provides 
continuous status display following operation in active mode. As 
discussed earlier, because delay start mode is not a mode that may 
persist for an indefinite time, DOE believes that delay start mode 
would not be considered part of standby mode, but instead would be a 
form of active mode. DOE is not proposing amendments to the dishwasher 
test procedure to define ``delay start mode'' or to measure power 
consumption in this mode. DOE may consider amendments addressing delay 
start mode issues in a future dishwasher test procedure rulemaking 
conducted under the 7-year schedule requirements of the EISA 2007 
amendments to EPCA. (42 U.S.C. 6293(b)(1))
    Based on the proposed ``standby mode'' definition, cycle finished 
mode, a mode that provides a continuous status display and may persist 
for an indefinite time, would be considered as part of a standby mode. 
Therefore, DOE proposes in today's NOPR to define cycle finished mode 
for dishwashers as ``a mode which provides continuous status display 
following operation in active mode.'' Proposed provisions to measure 
energy use in delay start mode and cycle finished mode are discussed in 
section III.E.1.
2. Dehumidifiers
    DOE is aware of three additional relevant modes for dehumidifiers: 
(1) Delay start mode; (2) off-cycle mode; and (3) bucket full/removed 
mode. The definition for ``delay start mode'' for dehumidifiers is the 
same as that for dishwashers. ``Off-cycle mode'' is defined as a mode 
in which a dehumidifier has cycled off its main function by humidistat 
or humidity sensor, does not have its fan or blower operating, and will 
reactivate the main function according to the humidistat or humidity 
sensor signal. ``Bucket full/removed mode'' is defined as a mode in 
which the dehumidifier has automatically powered off its main function 
by detecting when the water collection bucket is full or has been 
removed. For the same reasons discussed earlier for dishwashers, DOE 
believes that delay start mode would not be considered a standby mode, 
but instead would be a form of active mode. Therefore, DOE is not 
proposing amendments to define or to measure power consumption in 
``delay start mode.'' DOE may consider amendments addressing delay 
start mode issues in a future dehumidifier test procedure rulemaking 
conducted under the 7-year schedule requirements of the EISA 2007 
amendments to EPCA. (42 U.S.C. 6293(b)(1))
    DOE believes that off-cycle mode and bucket full/removed mode are 
modes that may persist for an indefinite time and, under the proposed 
definition, would be considered as part of standby mode. Therefore, DOE 
proposes amending its dehumidifier test procedure to include 
definitions of ``off-

[[Page 75299]]

cycle mode'' and ``bucket full/removed mode.'' Proposed provisions to 
measure energy use in delay start mode, off-cycle mode, and bucket 
full/removed mode are discussed in section III.E.2.
3. Conventional Cooking Products
    DOE is aware of three additional relevant modes for conventional 
cooking products: (1) Delay start mode; (2) cycle finished mode; and 
(3) Sabbath mode. ``Delay start mode'' and ``cycle finished mode'' are 
defined as for dishwashers. ``Sabbath mode'' is defined as a mode in 
which the automatic shutoff is overridden to allow for warming of pre-
cooked foods during such periods as the Jewish Sabbath. For the same 
reasons as discussed for dishwashers and dehumidifiers, DOE believes 
that delay start mode would not be considered a standby mode, but 
instead would be a form of active mode. Therefore, DOE is not proposing 
amendments to define or to measure power consumption in ``delay start 
mode.'' In addition, DOE believes that the Sabbath mode function of 
warming food would also be considered part of the active mode. 
Therefore, DOE is not proposing amendments to define or to measure 
power consumption in ``Sabbath mode.'' DOE may consider amendments 
addressing delay start mode and Sabbath mode issues in a future cooking 
products test procedure rulemaking conducted under the 7-year schedule 
requirements of the EISA 2007 amendments to EPCA. (42 U.S.C. 
6293(b)(1))
    DOE believes that cycle finished mode is a mode that may persist 
for an indefinite time and, under the proposed definition, would be 
considered as part of standby mode. Therefore, DOE proposes to amend 
its conventional cooking products test procedure to include a 
definition of ``cycle finished mode.'' Proposed provisions to measure 
energy use in delay start mode and cycle finished mode are discussed in 
section III.E.3.
    As discussed in section III.B, DOE proposes to amend the test 
procedures for residential dishwashers, dehumidifiers, and conventional 
cooking products to define ``off mode'' as a mode in which the product 
is connected to a mains power source and is not providing any active 
mode or standby mode function, and where the mode may persist for an 
indefinite time. An indicator that shows the user only that the product 
is in the off positions is included within the classification of off 
mode. As noted in section III.B, this definition of ``off mode'' is 
based on the definitions provided in IEC Standard 62301 (FDIS) and is 
useful in terms of expanding the scope of the EPCA mode definitions to 
clarify which functions are associated with off mode.
    Under the proposed definitions, a dishwasher, dehumidifier, or 
conventional cooking product equipped with a mechanical on/off switch 
that can disconnect power to the display and/or control components 
would be considered as operating in the off mode when the switch is in 
the ``off'' position, provided that no other standby mode or active 
mode functions are energized. An energized light-emitting diode (LED) 
or other indication that shows the user only that the product is in the 
off position would be considered part of off mode under the proposed 
definition, again provided that no other standby mode or active mode 
functions are energized. However, if any energy is consumed by the 
appliance in the presence of a one-way remote control, the unit would 
be considered to be operating in standby mode because the remote 
control would be used to activate or deactivate other mode(s). 
Electrical leakage and any energy consumed for electrical noise 
reduction, which are not specifically categorized as standby power 
functions, would be indicative of off mode and would be measured by the 
proposed amended test procedures.
    Section 3.7 of IEC Standard 62301 (FDIS) also defines ``network 
mode'' as a mode category that includes ``any product modes where the 
energy using product is connected to a mains power source and at least 
one network function is activated (such as reactivation via network 
command or network integrity communication) but where the primary 
function is not active.'' Section 3.7 of IEC Standard 62301 (FDIS) also 
provides a note, stating that ``[w]here a network function is provided 
but is not active and/or not connected to a network, then this mode is 
not applicable. A network function could become active intermittently 
according to a fixed schedule or in response to a network requirement. 
A `network' in this context includes communication between two or more 
separately independently powered devices or products. A network does 
not include one or more controls which are dedicated to a single 
product. Network mode may include one or more standby functions.''
    DOE acknowledges that in the future, products that are the subject 
of this rulemaking could incorporate a network mode for either 
communication with technicians for repair and performance monitoring, 
or for interaction with the electric grid. At this time, however, DOE 
is unaware of any data that would enable it to determine appropriate 
testing procedures and mode definitions for incorporation into test 
procedures for network mode in dishwashers, dehumidifiers, and 
conventional cooking products. This makes it extremely difficult to 
consider evaluation of a networked unit, even in terms of categorizing 
it as a standby mode or off mode function. In particular, DOE is 
unaware of methods for appropriately configuring networks or methods 
for collecting data about the energy use of appropriately configured 
networks. DOE also has no information as to whether network connection 
speed or the number and type of network connections affect power 
consumption for these products. DOE also has no information as to 
whether wireless network devices in such products would have different 
levels of power consumption when a device is looking for a connection 
versus when the network connection is established. DOE is also unaware 
of how the energy consumption for dishwashers, dehumidifiers, and 
conventional cooking products in a network environment may be affected 
by their product design and user interaction, as well as network 
interaction. These effects would need to be measured both if the 
network function could become active intermittently according to a 
fixed schedule or in response to a network requirement. For these 
reasons, the amendments proposed in today's NOPR do not include 
provisions for testing network mode energy consumption in dishwashers, 
dehumidifiers, and conventional cooking products. Provisions for 
testing power consumption in network mode could be incorporated into 
the test procedure through future amendments once the appropriate data 
and testing methodologies become available. DOE welcomes comment on 
whether dishwashers, dehumidifiers, or conventional cooking products 
that incorporate a networking function are currently available, and 
whether definitions and testing procedures for a network mode should be 
incorporated into the DOE test procedures. DOE also requests comment on 
appropriate testing methodologies for measuring energy consumption in a 
network mode for dishwashers, dehumidifiers, and conventional cooking 
products, and data on the repeatability of those testing methodologies.
    DOE also notes that section 3.9 of IEC Standard 62301 (FDIS) 
provides a definition for ``disconnected mode,'' which is ``the state 
where all connections to mains power sources of

[[Page 75300]]

the energy using product are removed or interrupted.'' IEC Standard 
62301 (FDIS) also adds a note that common terms such as ``unplugged'' 
or ``cut off from mains'' also describe this mode and that this mode is 
not part of off mode, standby mode, or network mode. DOE believes that 
there would be no energy use in a disconnected mode and agrees that it 
would not be part of off mode, standby mode, or network mode. 
Therefore, DOE is not proposing a definition or testing method for 
disconnected mode in the test procedures for residential dishwashers, 
dehumidifiers, or conventional cooking products.

D. Specifications for the Test Methods and Measurements for Standby 
Mode and Off Mode Testing

    DOE proposes amending its test procedures to include provisions for 
measuring the power consumption of dishwashers, dehumidifiers, and 
conventional cooking products in all standby and off modes. This 
section first discusses issues relevant to all three types of products 
subject to this rulemaking, and then, it subsequently addresses issues 
specific to each product type. As an initial matter, DOE would clarify 
the provisions it proposes to include in the test procedures to clarify 
the IEC Standard 62301 (First Edition) methods when used to measure 
standby mode and off mode energy use in dishwashers, dehumidifiers, and 
conventional cooking products. These proposed amendments also include 
provisions for measuring energy use in cycle finished mode for 
dishwashers, off-cycle mode and bucket full/removed mode for 
dehumidifiers, and cycle finished mode for conventional cooking 
products.
    For all three products, DOE is proposing a test method based on the 
provisions from IEC Standard 62301 (First Edition). Paragraph 5.3.1 of 
IEC Standard 62301 (First Edition) specifies the following test method 
for products in which the power varies by not more than 5 percent from 
a maximum level during a period of 5 minutes: (1) Wait at least 5 
minutes after selecting the mode to be measured for the product to 
stabilize; and (2) measure the power consumption at the end of an 
additional time period of not less than 5 minutes.
    IEC Standard 62301 (First Edition), paragraph 5.3.2, contains 
provisions for measuring average power in cases where the power is not 
stable (i.e., the measured power varies by more than 5 percent from a 
maximum level during a period of 5 minutes). Such instances can 
include, for example, a clock display whose power consumption varies as 
a function of the time displayed or internal electronic components 
which are cycled on and off regularly. In such cases, IEC Standard 
62301 (First Edition) requires a measurement period of no less than 5 
minutes, or, if there is an operating cycle (defined as a regular 
sequence of power states that occur over several minutes or hours), one 
or more complete cycles. DOE notes these provisions do not preclude 
manufacturers from testing products with a longer stabilization period, 
or a longer measurement period, as long as the power does not vary by 
more than 5 percent or the stabilization period represents one or more 
complete cycles. DOE expects results obtained under such conditions 
would be comparable to those obtained using the minimum allowable 
stabilization and measurement periods.
    DOE is aware that residential dishwashers and conventional cooking 
products with displays may reduce power consumption by dimming after a 
period of user inactivity (known as ``automatic power-down''). For 
products whose power consumption in inactive mode varies in this manner 
during testing, DOE proposes that the test be conducted after the power 
level has dropped to its lowest level, as discussed in IEC Standard 
62301 (First Edition), section 5, paragraph 5.1, Note 1. DOE believes 
that products with automatic power-down spend more time in this low-
power state than in the higher-power state. Thus, the energy 
consumption at the low-power level is most representative of inactive 
mode power range.
    DOE is aware that IEC Standard 62301 (First Edition) does not 
provide guidance on how long to wait for the appliance to drop to the 
lower-power state. DOE tested 14 dishwashers, 13 dehumidifiers, and 41 
conventional cooking products and observed that units with an automatic 
power-down feature persisted in the higher-power state for less than 10 
minutes of user inactivity after the display has initially been 
energized. However, the test sample was small and may not be 
sufficiently representative. It is possible that some dishwashers, 
dehumidifiers, and conventional cooking products may remain in the 
higher-power state for the duration of a 5-minute stabilization period 
and subsequent 5-minute measurement period, and then drop to the lower-
power state that is more representative of inactive mode. In contrast, 
IEC Standard 62301 (CDV) specifies for each testing method that the 
product shall be allowed to stabilize for at least 30 minutes prior to 
a measurement period of not less than 10 minutes. DOE believes this 
specification would allow sufficient time for all displays that 
automatically dim or power down after a period of user inactivity to 
reach the lower-power state prior to measurement. DOE believes that the 
IEC Standard 62301 (CDV) 30-minute stabilization and 10-minute 
measurement periods provide a clearer and more consistent testing 
procedure than the corresponding time periods specified in IEC Standard 
62301 (First Edition). Those periods allow for representative 
measurements to be made among products that may have varying time 
periods before the power drops to a lower level more representative of 
standby mode, off mode, or cycle finished mode.
    DOE notes that IEC Standard 62301 (FDIS) establishes an overall 
test period of not less than 15 minutes for products in which power 
consumption in the mode being tested is not cyclic. Data collected 
during the first third of the total period are discarded (and, thus, 
this time could be inferred to be a stabilization period), and data 
from the remaining two-thirds of the total period are used to determine 
whether the power is stable. If stability is not achieved, the total 
period is extended continuously until the stability criteria are 
achieved, to a maximum of 3 hours. Modes that are known to be non-
cyclic and of varying power consumption shall follow this same 
procedure, but with a total test period not less than 60 minutes. If 
power consumption in a mode is cyclic, measurements must be conducted 
with an initial operation period (analogous to a stabilization period) 
of at least 10 minutes, and the average power measured over at least 
four complete cycles. The measurement period must be at least 20 
minutes. After careful consideration, DOE has tentatively concluded 
that the specifications provided in IEC Standard 62301 (FDIS) would not 
produce power consumption measurements as accurate, repeatable, and 
enforceable as the specifications provided in IEC Standard 62301 (CDV). 
Therefore, DOE proposes to require that dishwashers, dehumidifiers, and 
conventional cooking products be allowed to stabilize for at least 30 
minutes prior to a power measurement period of not less than 10 
minutes. (For the reasons discussed in section III.D.3, DOE is 
proposing a choice between different methodologies for the specific 
case in which conventional cooking product energy use in standby mode 
varies as a function of the time displayed on a clock. In such case, 
DOE proposes to specify setting the clock to a particular start time at 
the

[[Page 75301]]

end of a 10-minute stabilization period, waiting another 10 minutes for 
the product again to stabilize, and then measuring standby power over a 
period of 10 minutes. Alternatively, DOE proposes that manufacturers, 
at their own discretion, may choose to measure standby power over a 12-
hour period that captures all possible variations of power consumption 
as a function of the time displayed.) Although DOE did not observe any 
dehumidifiers with displays that automatically powered down, DOE is 
proposing the 30-minute stabilization and 10-minute power measurement 
periods for those products as well in order to account for currently 
available or future models that may have such a feature.
    DOE's test procedures are developed to measure representative 
energy use for the typical consumer and cannot capture all possible 
consumer actions and appliance usage patterns that might increase 
energy use. For example, certain products featuring a display power-
down may allow consumers to alter the display settings to increase the 
amount of time in the high-power state, or to make the high-power state 
permanent. However, DOE believes the typical consumer will not alter 
the standard or default settings. Therefore, DOE has not proposed 
additional provisions in today's NOPR to address the possibility of 
increased energy use as a result of consumers adjusting the display 
power-down settings or other features. DOE welcomes comment on the 
suitability of using the default settings in testing standby mode 
energy consumption. It also welcomes comment on any testing 
methodologies that can account for consumer actions that might increase 
energy use, and requests data on the repeatability of those testing 
methodologies.
    The following sections describe the proposed test method that is 
specific to each of the three products that are the subject of this 
rulemaking.
1. Dishwashers
    DOE proposes that test room ambient temperatures for standby mode 
and off mode testing be specified for all dishwashers according to 
section 4, paragraph 4.2 of IEC Standard 62301 (First Edition). The IEC 
standard specifies a temperature range of 73.4  9 [deg]F. 
The current DOE test procedure for dishwashers includes a test room 
ambient air temperature requirement of 75  5 [deg]F. The 
narrower range of allowable ambient temperature in the DOE test 
procedure helps ensure consistent and repeatable test results for 
active mode measurements in which heat losses could affect energy 
consumption, but energy use in standby mode or off mode are less 
affected by ambient temperature. Today's proposed test procedure would 
allow manufacturers of dishwashers to use the more stringent ambient 
temperature range in the current DOE test procedure if tests of active 
mode efficiency performance and standby mode and off mode power 
consumption are conducted simultaneously in the same room on multiple 
dishwashers. Alternatively, the proposed temperature specifications 
taken from IEC Standard 62301 (First Edition) would allow a 
manufacturer that opts to conduct standby mode and off mode testing 
separately from active mode testing more latitude in maintaining 
ambient conditions. DOE requests comment on the appropriateness of this 
proposed modified test room ambient temperature range.
2. Dehumidifiers
    DOE proposes that test room ambient temperatures for standby mode 
and off mode testing be specified for all dehumidifiers according to 
section 4, paragraph 4.2 of IEC Standard 62301 (First Edition). The IEC 
standard specifies a temperature range of 73.4  9 [deg]F. 
The current DOE test procedure for dehumidifiers references the ENERGY 
STAR test criteria for dehumidifiers. The ENERGY STAR test criteria are 
based on ANSI/AHAM Standard DH-1-2003, ``Dehumidifiers,'' which 
specifies a test room ambient temperature of 80  2 [deg]F 
for testing. Today's proposed test procedure would allow manufacturers 
of dehumidifiers to conduct active mode efficiency performance testing 
and standby mode and off mode power consumption testing simultaneously 
in the same room on multiple dehumidifiers, as long as the temperature 
requirements for both tests are met. Alternatively, the proposed 
temperature specifications taken from IEC Standard 62301 (First 
Edition) would allow a manufacturer that opts to conduct standby mode 
and off mode testing separately from performance testing to use the 
ambient temperature requirement of 73.4  9 [deg]F. DOE 
requests comment on the appropriateness of this proposed modified test 
room ambient temperature range.
    DOE also proposes additional clarifications to the power supply 
requirements for standby mode and off mode testing for dehumidifiers to 
require that the power supply frequency be the rated frequency  1 percent. The current DOE dehumidifier test procedure requires 
that the power supply for the active mode test have a supply voltage of 
115/230 volts (V)  2 percent (depending on the voltage 
specified on the name plate), and be at the rated frequency (no 
allowable range is specified for the latter). DOE notes that section 4, 
paragraph 4.3 of IEC Standard 62301 (First Edition) states that when 
IEC Standard 62301 is referenced by an external standard, the test 
voltage and frequency defined by the external standard shall be used. 
When the test voltage and frequency are not defined by the external 
standard, IEC Standard 62301 (First Edition) requires that the supply 
voltage and frequency be 115 V  1 percent and 60 Hertz (Hz) 
 1 percent, respectively. Because the current DOE 
dehumidifier test procedure specifies that the rated frequency be used 
for testing but does not provide an allowable range, DOE proposes that 
the range of  1 percent specified by IEC Standard 62301 
(First Edition) be used for standby mode and off mode testing. DOE 
requests comments on its proposed amendments related to frequency.
3. Conventional Cooking Products
    DOE proposes that test room ambient temperatures for standby mode 
and off mode testing be specified for all conventional cooking 
products, including cooktops, ovens, and ranges, according to section 
4, paragraph 4.2 of IEC Standard 62301 (First Edition). The IEC 
standard specifies a temperature range of 73.4  9 [deg]F. 
The current DOE test procedure for conventional cooking products 
includes a test room ambient air temperature specification of 77  9 [deg]F. This varies slightly from the range specified by IEC 
Standard 62301 of 73.4  9 [deg]F. DOE believes that the 
higher temperatures allowed for active mode energy testing could be 
representative of ambient temperatures during a cooking process, but 
that it would be appropriate to maintain lower allowable temperatures 
for standby mode and off mode power consumption measurements as to be 
more representative of ambient conditions during those operating modes. 
The proposed test procedure would allow manufacturers of conventional 
cooking products to measure active mode performance and standby and off 
mode power simultaneously in the same room on multiple units, provided 
that the room ambient temperature falls within the range allowed by 
both ambient temperature requirements (i.e., any temperature between 68 
and 82.4 [deg]F). Alternatively, the proposed temperature 
specifications from IEC Standard 62301 (First Edition) would allow a 
manufacturer to conduct standby mode and off mode testing separately 
from

[[Page 75302]]

performance testing within an ambient temperature range of 73.4  9 [deg]F. DOE requests comment on the appropriateness of this 
proposed modified test room ambient temperature range.
    DOE also proposes additional clarifications to the power supply 
requirements for standby mode and off mode testing for conventional 
cooking products to require that the power supply frequency be 60 Hz 
 1 percent. The current DOE conventional cooking products 
test procedure requires that the power supply for the active mode test 
be 240/120 V  2 percent or 208/120  2 percent 
(for basic models rated only at that rating), but the test procedure 
does not specify any power supply frequency requirements. As discussed 
earlier for dehumidifiers, section 4, paragraph 4.3 of IEC Standard 
62301 (First Edition) states that when the test voltage and frequency 
are not defined, the supply voltage and frequency shall be 115 V  1 percent and 60 Hz  1 percent, respectively. 
Because the current DOE conventional cooking products test procedure 
does not specify a power supply frequency, DOE proposes that the 60 Hz 
 1 percent specified by IEC Standard 62301 (First Edition) 
be used for standby mode and off mode testing. DOE requests comments on 
its proposed amendments related to frequency.
    IEC Standard 62301 (First Edition) is written to provide some 
flexibility so that the test standard can be used to measure standby 
mode and off mode power for most household electrical appliances 
(including conventional cooking products). For that reason, it does not 
specify closely the test method for measuring the power consumption in 
cases in which the measured power is not stable. Section 5.3.2 of IEC 
Standard 62301 (First Edition) states that ``[i]f the power varies over 
a cycle (i.e., a regular sequence of power states that occur over 
several minutes or hours), the period selected to average power or 
accumulate energy shall be one or more complete cycles in order to get 
a representative average value.'' DOE investigated the possible regular 
sequences of power states for conventional cooking products in order to 
propose clarifying language to IEC Standard 62301 (First Edition) that 
would provide accurate and repeatable test measurements.
    DOE's tests of standby power measurement in conventional cooking 
products indicate that a given unit or model with a clock display may 
use varying amounts of standby power depending on the clock time being 
displayed. DOE tested a small number (7) of conventional cooking 
products from its test sample to determine the amount of variation in 
power consumption that is possible due to variations in the clock time 
being displayed. More specifically, DOE tested the products with clock 
settings of 1:11 and 12:08, which represent the minimum and maximum 
amount of numerical display segments.\11\ Table III.1 shows the test 
results for the products that showed significant variation in power 
consumption depending upon the clock's time display. According to DOE 
tests of conventional cooking products equipped with a 12-hour clock 
display, standby power use at different times during a 12-hour cycle 
could vary by as much as 44 percent.
---------------------------------------------------------------------------

    \11\ Each clock time was tested three times to confirm that the 
results were repeatable. The table shows the average power of the 
three tests.

    DOE believes that the lack of specificity in IEC Standard 62301 
(First Edition) about the test period could produce test results 
obtained during one time period that are not comparable to those 
obtained using other time periods. Such results would not necessarily 
represent the standby power consumption of conventional cooking 
products during all hours associated with standby mode. In addition, 
different testing laboratories could take different approaches in 
selecting cycles for testing. To assess alternatives to the test cycle 
specified in IEC Standard 62301 (First Edition), DOE investigated 
alternative time periods and averaging methods for calculating 
representative standby power use, using data that DOE collected from 
microwave oven clock displays during its analyses for energy 
conservation standards for those products. DOE believes that those 
displays have cyclic variation in power consumption as a function of 
displayed time comparable to those in conventional cooking products.
    For a typical microwave oven display with a 12-hour clock feature, 
DOE measured average standby power over the full 12-hour period. This 
measurement provides the most accurate and repeatable results. However, 
because a 12-hour test could substantially add to manufacturer test 
burden, DOE sought to identify other, more-abbreviated testing options, 
all the while keeping the 12-hour test in mind as an appropriate frame 
of reference in terms of generating representative results. DOE then 
evaluated a method using 18 different clock display times to produce an 
average standby power measurement representative of a 12-hour cycle. 
(This is referred to as the ``18-point method.'') This method was 
discussed in appendix 5B of the technical support document (TSD) for 
the November 2007 ANOPR. When this method is used, the standby power 
consumption and line voltage are measured as the clock is cycled 
through all the possible digit combinations (in terms of active 
elements).\12\ A regression

[[Page 75303]]

analysis is then performed to quantify the effect of the number of lit 
elements (by digit) and voltage on power consumption. The results were 
integrated across the number of minutes that each active element 
combination was ``on'' through the course of the 12-hour test period. 
As noted in chapter 5 of the November 2007 ANOPR TSD, this methodology 
produced results for average standby power consumption that were within 
1 to 2 percent of the 12-hour test results.
---------------------------------------------------------------------------

    \12\ The term ``active elements'' refers to the number of 
display segments energized in a seven-segment clock display for a 
given time. Different digit combinations associated with different 
times displayed may have the same number of active elements.
---------------------------------------------------------------------------

    DOE also investigated whether a single 10-minute measurement period 
with a starting clock time of 3:33 would be a reasonable proxy for the 
12-hour standby power measurement in the event that power consumption 
is not stable. DOE's analysis indicates that the proportion of time 
that each possible number of segments in a 7-segment LED display that 
are lit over the 10-minute time period from 3:33 to 3:42 is 
representative of the distribution of lit segments over a 12-hour 
period with an arbitrary starting time.\13\ This suggests that the 10-
minute test period starting at 3:33 would produce average standby power 
measurements comparable to average standby power measured over 12 
hours. Table III.2 shows the average standby power measured for 11 
units in DOE's microwave oven test sample using the 18-point and 10-
minute methodologies as compared to the 12-hour test.

* Standby power measurements are scaled to normalize the supply power to 120.0 volts.
** For this test, the supply power was significantly different than 120.0 volts. Therefore, DOE believes the scaling of the measured standby power and,
  thus, the percentage differences from the 12-hour standby power measurements are not valid for this test unit.

    Within DOE's limited test sample, the average standby power 
measured over the specified 10-minute test period agrees within  2 percent of the average standby power measured over 12 hours. 
Therefore, DOE tentatively concludes that a 10-minute measurement 
period with a starting time of 3:33 would provide a valid measure of 
standby energy use for conventional cooking products, with power 
consumption varying according to the time displayed on the clock. DOE 
requests comment on the validity and comparability of the various tests 
examined, as well as which test(s) DOE should adopt for measuring 
standby mode and off mode energy use.
    As a related matter, DOE is aware that certain clock displays enter 
a higher-power state when one manually sets the time, and then after a 
prescribed interval, the clock enters a lower-power state (e.g., by 
dimming the display) that is representative of the power levels that 
would be associated with the display running without consumer 
interaction. Therefore, DOE has tentatively concluded that it would be 
appropriate to provide a second stabilization period after the clock 
display is set prior to the start of the measurement period. DOE 
testing of combination microwave ovens, which have similar clock 
displays as conventional cooking products, suggest that a second 
stabilization period of 10 minutes would be sufficient to ensure that 
the clock display has reached its more representative power state after 
setting the time. This approach would require setting the clock time to 
3:23 in order to start the measurement period at 3:33 after the 10-
minute second stabilization period. Therefore, DOE has tentatively 
decided to specify that, for conventional cooking products for which 
standby power consumption is not stable, the clock display shall be set 
at 3:23 at the conclusion of the stabilization period specified in 
section 5.3 of IEC Standard 62301 (First Edition), after which a second 
10-minute stabilization period shall be provided, and the subsequent 
test period shall be 10 minutes. Alternatively, DOE believes that 
appropriate stabilization may be achieved by requiring only the 10-
minute stabilization period after setting the clock time to 3:23. DOE 
seeks comment on whether this alternative method in which the clock 
time is set to 3:23 prior to a 10-minute stabilization period, followed 
by a 10-minute measurement period commencing at 3:33 would be 
appropriate.
    DOE acknowledges, however, that both the 18-point and 10-minute 
approaches for accelerated standby testing do not exclude the 
possibility that a product could be programmed to alter its behavior 
during such a test in order to minimize measured standby power 
consumption. For example, a conventional cooking product could be 
programmed to dim or alter its display only during the display times 
associated with the 18 measurement points or between display times 3:33 
and 3:42.
    In light of the above, DOE is proposing to provide manufacturers of 
conventional cooking products the option to conduct either the full 12-
hour test, the 10-minute test, or both (with the expectation that any 
test records will make clear which type of test(s) was (were) 
performed). If a manufacturer elects to perform both

[[Page 75304]]

tests on a unit, the manufacturer may only use the results from one of 
the tests (i.e., the 12-hour test or the 10-minute test) as the test 
results for that unit. For purposes of enforcement testing, DOE 
reserves the right to use either test or both tests. Given that the 10-
minute test, like the 12-hour test, is intended to represent standby 
mode and off mode energy use and based upon the research data discussed 
above, DOE proposes to clarify that the test results conducted under 
the two different tests must be within  2 percent 
of each other; otherwise, DOE will use the 12-hour test to determine 
compliance. DOE requests comment on its proposed approach requiring 
results under the 12-hour test and the 10-minute test to be within 
 2 percent of each other and welcomes data which 
would show that some other range is more appropriate.
    DOE notes that the conventional cooking products test procedure is 
designed to provide an energy efficiency measurement consistent with 
representative average consumer use of these products, even if the test 
conditions and/or procedures may not themselves all be representative 
of average consumer use (e.g., testing with a display of only 3:33 to 
3:42). DOE's proposal reflects the statutory requirement, and the 
Department's longstanding view, that the overall objective of the test 
procedure is to measure the product's energy consumption during a 
representative average use cycle or period of use. 42 U.S.C. 
6293(b)(3). Further, the test procedure requires specific conditions 
during testing that are designed to ensure repeatability while avoiding 
excessive testing burdens. Although certain test conditions specified 
in the test procedure may deviate from representative use, such 
deviations are carefully designed and circumscribed in order to attain 
an overall calculated measurement of the energy consumption during 
representative use. Thus, it is--and has always been--DOE's view that 
products should not be designed such that the energy consumption drops 
during test condition settings in ways that would bias the overall 
measurement, thereby making it unrepresentative of average consumer 
use. If a manufacturer incorporates a power-saving mode as part of the 
appliance's routine operation, DOE's test procedure would produce a 
representative measure of average consumer use if the unit powered down 
during the 10-minute test period for the same percentage of time that 
such powering down would be expected to occur during a typical 12-hour 
period, and, thus, such operation would be permissible. Although DOE 
believes that its proposed 10-minute test would be adequate for standby 
mode and off mode testing purposes, if it becomes aware of product 
design strategies which render the 10-minute test results 
unrepresentative, DOE reserves the right to perform a full 12-hour test 
in the context of enforcement testing. It has been the Department's 
long-held interpretation that the purpose of the test procedure is to 
measure representative use. Ultimately, if DOE identifies a broad 
pattern of behavior which has the effect of circumventing its test 
procedure provisions, the Department may consider reopening the 
conventional cooking products test procedure for further rulemaking.
    DOE proposes to clarify in the conventional cooking products test 
procedure codified in 10 CFR 430.23(i)(17) that the energy test 
procedure is designed to provide a measurement consistent with 
representative average consumer use of the product, even if the test 
conditions and/or procedures may not themselves all be representative 
of average consumer use (e.g. specified display times). However, in a 
proposed rule on certification, compliance, and enforcement published 
in the Federal Register on September 16, 2010, DOE proposed that it 
would be a prohibited act to either fail to test a covered product in 
conformance with applicable test procedure requirements or to engage in 
``deliberate use of controls or features in a covered product or 
covered equipment to circumvent the requirements of a test procedure 
and produce test results that are unrepresentative of a product's 
energy or water consumption if measured pursuant to DOE's required test 
procedure.'' 75 FR 56796, 56825 (Sept. 16, 2010) (citing proposed 
amendments to 10 CFR 429.31(a)(2)). Examples of products exhibiting 
such behavior are those products that can exhibit operating parameters 
(e.g. display wattage) for any energy using component that are not 
predictably varying functions of operating conditions or control 
inputs--such as when a display is automatically dimmed when test 
conditions or test settings are reached. DOE believes that retention of 
the ability to conduct enforcement testing using the 12-hour test will 
deter product designs that would not be representative under the 10-
minute test of the DOE test procedure.
    DOE seeks comment on the proposed approach above to address 
products equipped with controls or other features that modify the 
operation of energy-using components during testing. DOE's proposed 
approach does not identify specific product characteristics that could 
render results generated under the test procedure unrepresentative when 
testing certain products (e.g. modification of operation based on 
display time). Rather, it clarifies the need to address any features 
that could potentially yield measurements unrepresentative of the 
product's energy consumption during a representative use cycle.
    As discussed in section III.B, the current DOE conventional cooking 
products test procedure provides testing methods and calculations to 
account for energy use of a continuously-operating clock. The current 
test procedure requires that any electrical clock that uses energy 
continuously be disconnected, except for those that are an integral 
part of the timing or temperature-controlling circuit of the product. 
In cases where the continuously-operating clock is an integral part of 
the timing or temperature-control circuit and cannot be disconnected 
during the test, the test procedure requires that such clock energy use 
be subtracted from the oven, cooktop, or range test energy consumption. 
The test procedure also provides methods for measuring the power 
consumption of a clock, which is then multiplied by 8,760 hours (total 
hours per year) to determine the annual clock energy consumption. The 
annual clock energy consumption is included in the calculation of total 
annual energy consumption and EF.
    DOE believes that the testing provisions for clock energy 
consumption currently in the cooking products test procedure are no 
longer necessary because DOE proposes to amend the conventional cooking 
products test procedure to fully account for standby mode and off mode 
energy consumption, which include clock energy consumption. DOE 
proposes to incorporate standby mode and off mode energy consumption 
into the total annual energy consumption and EF calculations. 
Therefore, DOE proposes to remove the provisions for clock energy 
consumption from the conventional cooking products test procedure and 
to replace them with the provisions for measuring all standby mode and 
off mode energy consumption. (See section III.E.)

E. Calculation of Energy Use Associated With Standby Mode and Off Mode

    Measurements of power associated with standby mode and off mode for

[[Page 75305]]

dishwashers, dehumidifiers, and conventional cooking products are 
expressed in watts (W). The annual energy consumption in each of these 
modes is the product of the power consumption and the time spent in 
that particular mode per year. The following sections describe how the 
annual energy use associated with each operating mode is calculated for 
the products that are the subject of this rulemaking.
1. Dishwashers
    Energy use for dishwashers is expressed in terms of average annual 
energy use and total energy used per dishwasher cycle. (10 CFR 
430.23(c)) As discussed in section III.F, DOE has tentatively 
determined that it is technically feasible to incorporate measures of 
standby mode and off mode energy use into the overall energy use metric 
(i.e., average annual energy use) as required by the EISA 2007 
amendments to EPCA. (42 U.S.C. 6295(gg)(2)(A)) Therefore, DOE has 
examined standby mode and off mode energy consumption in terms of 
annual energy use, expressed in kWh per year.
    In the current DOE dishwasher test procedure, the annual standby 
mode energy consumption is calculated by multiplying the average 
standby power use by the number of standby hours per year. The number 
of standby hours per year is equal to the number of total hours per 
year minus the product of the representative average dishwasher use of 
215 cycles per year times the average wash cycle time. The average wash 
cycle time is derived from test measurements of the duration of the 
various cycles available on a dishwasher, such as normal, truncated 
normal, and sensor cycles. The average standby energy consumption is 
then added to the annual machine energy use (which includes any water 
heating within the dishwasher) and annual water energy use (energy used 
by the residence's water heater to heat the water prior to being 
supplied to the dishwasher during the cycle) to calculate the EAEU. DOE 
is proposing in today's NOPR that the active mode hours be determined 
using the approach specified in the current DOE dishwasher test 
procedure. That procedure uses test measurements of the duration of the 
various cycles available on a dishwasher to determine its average wash 
cycle time and then multiplies that average wash cycle time by 215 
cycles per year. DOE proposes that the remaining non-active hours be 
distributed between the appropriate standby and off modes. DOE 
investigated the annual hours and energy consumption associated with 
each possible dishwasher operating mode, including inactive, delay 
start, cycle finished, off, and active modes, in order to propose 
methods for calculating the total annual energy use.
    As part of the November 2007 ANOPR, DOE estimated the length of a 
dishwasher cycle to be one hour. 72 FR 64432, 64471 (Nov. 15, 2007). 
The DOE test procedure assumes 215 dishwasher cycles per year. (10 CFR 
part 430 subpart B, appendix C, section 5.6) Therefore, DOE estimates 
that 215 hours per year are dedicated to active mode.
    Data regarding the amount of time dishwashers spend in the 
remaining non-active modes is very limited. A study conducted in 
Australia, ``2005 Intrusive Residential Standby Survey Report,'' 
surveyed 120 households and provided information regarding delay start 
for dishwashers. The report stated that about 25 percent of dishwashers 
were found to have delay start capabilities. Twenty percent of those 
surveyed who had dishwashers with delay start capabilities indicated 
they used this function. The study also reported an average power 
consumption for delay start mode of 3.8 W.\14\ DOE notes the study 
reported data on dishwashers installed in the households at the time of 
the survey. Thus, the data may not be representative of dishwashers 
currently on the market. Because this study provided only limited 
information on consumer usage patterns for a limited number of modes, 
DOE investigated other sources of consumer usage data for dishwashers 
regarding the amount of time dishwashers spend in each possible non-
active mode.

---------------------------------------------------------------------------

    One IEC report \15\ surveyed dishwasher usage patterns in Germany, 
Italy, and the United Kingdom households. Dishwashers in these 
households averaged 213 cycles per year, which is close to the value 
specified by the current DOE dishwasher test procedure of 215 cycles 
per year. DOE believes the results of this survey are consistent with 
consumer behavior in the United States. DOE notes that the sample size 
of this survey was only 79 households. Regarding delay start, called 
``time delay function'' in the survey, data showed 44 percent of 
dishwashers had a delay start function. Thirty-four percent of the 
respondents who owned a dishwasher with a delay start function used the 
function. Respondents who did use delay start used it for 16 percent of 
all cycles, with an average delay setting of 5.1 hours. If the results 
for delay start are applied to all dishwashers and cycles, the average 
delay start per cycle is just under 8 minutes, or 26 hours per year. 
For cycle finished mode, called ``program end'' in the survey, data 
from all households showed the average time after program end and 
before switching the machine off was 1.1 hours. If results for cycle 
finished mode are applied to all dishwashers and cycles, the average 
total cycle finished mode hours is 237 hours per year.

    DOE is using data from this IEC survey in its estimates of the 
energy consumption associated with the different dishwasher modes. Of a 
total 8,760 hours per year,\16\ the hours not associated with active, 
delay start, or cycle finished mode are allocated to off and inactive 
modes. To determine the approximate wattages associated with standby 
modes and off mode, DOE conducted internal testing on 14 
dishwashers.\17\ Average power levels in watts are multiplied by the 
estimated number of hours allocated per year to each mode to calculate 
the annual energy use for each mode. For example, the active mode power 
and annual energy use were calculated based on 215 cycles per year for 
a standard-size dishwasher with a minimum standard EF of 0.65. The 
typical average per-cycle energy use for such a dishwasher is 
calculated to be 1.54 kWh per cycle. The product of these inputs yields 
annual energy use in active mode of 331.1 kWh per year. In summary, 
Table III.3 presents the comparison of the average wattages and annual 
energy use associated with all dishwasher modes.

    \16\ DOE used a value of 8760 total hours per year in all of its 
analyses in today's notice, based on 24 hours/day x 365 days/year. 
The current dishwasher test procedure includes a value of 8766 
hours, which results from 24 hours/day x 365.25 days/year. Although 
the latter equation is more accurate, DOE has retained the value of 
8760 in all its proposed test procedure amendments in today's 
notice, and notes that the two values vary by a negligible 0.07 
percent.

                       Table III.3--DOE Estimate of Annual Energy Use of Dishwasher Modes

----------------------------------------------------------------------------------------------------------------
* Based on IEC 59A/122/INF.
** (8,760 hours per year--215 active mode hours--26 delay start hours--237 cycle finished hours) = 8,282 hours.

    As discussed in section III.C, DOE believes that delay start would 
not be considered part of standby mode, but instead, it would be an 
active mode. For the reasons discussed earlier, DOE is not proposing 
amendments to the dishwasher test procedure to define ``delay start 
mode'' or to measure power consumption in this mode. The comparison of 
annual energy consumption of different dishwasher modes presented in 
Table III.3 shows that energy use associated with delay start mode is 
relatively insignificant because of the small number of annual hours 
associated with this mode. In addition, the power levels in this mode 
are similar to those for off/inactive modes for dishwashers currently 
on the market. Therefore, DOE proposes to allocate delay start mode 
hours (which total 26 for this example case) to the inactive and off 
modes (which would then total 8,308 for this example case). DOE also 
proposes that 237 hours be associated with cycle finished mode for 
dishwashers capable of functioning in such a mode, as presented in 
Table III.3.
    To determine the annual hours per mode for dishwashers for which 
not all standby modes are possible, DOE proposes to reallocate the 
hours for modes that are not part of the dishwasher's design. For 
example, if cycle finished mode is not part of a dishwasher's design, 
the off/inactive mode hours would be the total hours per year minus the 
active mode hours per year. If cycle finished mode is part of the 
design, the off/inactive mode hours would be the total hours per year 
minus the active mode hours per year minus the 237 cycle finished mode 
hours.
    DOE believes that the proposed definition of ``off mode'' as 
applied to dishwashers refers to units with mechanical rather than 
electronic controls, or units with electronic controls combined with a 
mechanical switch, with which the user can de-energize the electronic 
controls. Reactivation of the dishwasher with a push-button sensor, 
touch sensor, or other similar device that consumes power is considered 
to be a standby mode feature under the proposed definition. The 
proposed definition states that standby mode facilitates the activation 
of other modes (including activation or deactivation of active mode) by 
remote switch (including remote control), internal sensor, or timer. 
DOE believes there are few dishwashers with electronic controls that 
have an additional mechanical on/off switch. Therefore, the combined 
inactive/off mode hours would most likely be allocated fully either to 
inactive or off mode, depending on the type of controls present on the 
dishwasher. DOE does not have market share information to determine how 
many dishwashers are currently shipped with electromechanical controls 
or the proportion of time spent in off mode for units equipped with a 
mechanical on/off switch. For dishwashers with electronic controls plus 
a mechanical on/off switch, DOE is proposing to allocate half of the 
non-active hours to inactive and half to off modes. DOE welcomes 
comment and additional information on this point, and on the proposed 
approach for calculating energy use for standby mode and off mode.
    In conclusion, DOE proposes to determine dishwasher standby mode 
and off mode energy use by: (1) Calculating the product of wattage and 
allocated hours for all possible standby and off modes; (2) summing the 
results; and (3) dividing the sum by 1,000 to convert from watt-hours 
(Wh) to kWh. DOE invites comments on this proposed methodology and 
associated factors, including accuracy, allocation of annual hours, and 
test burden for manufacturers. DOE may also consider adoption in the 
final rule of the following alternative methodology based on comments 
received.
    The comparison of annual energy use of different dishwasher product 
modes shows that cycle finished mode represents a relatively small 
number of hours per year at a low power consumption level. For 
dishwashers currently on the market, these levels are distinct from but 
comparable to those for off/inactive modes. Thus, DOE could adopt a 
test procedure for dishwashers that would specify that only hours spent 
in off and inactive modes would be considered when calculating energy 
use associated with standby mode and off mode. In that case, all of the 
non-active hours would be allocated to the inactive and off modes. DOE 
invites comment on whether such an alternative would be representative 
of the standby mode and off mode power consumption of dishwashers 
currently on the market.
2. Dehumidifiers
    Energy use for dehumidifiers is expressed as EF, which is the ratio 
of liters of water removed from the air per kWh. As discussed in 
section III.F, DOE has determined it is technically feasible to 
incorporate measures of standby mode and off mode energy use into the 
overall energy use metric, and accordingly, DOE is making a proposal 
consistent with that determination, as required by the EISA 2007 
amendments to EPCA. (42 U.S.C. 6295(gg)(2)(A)) Thus, DOE proposes that 
a dehumidifier's total annual energy use be estimated by combining 
standby mode and off mode energy consumption with active mode 
consumption based on the number of hours a dehumidifier spends in each 
mode.
    In order to establish the number of hours per year a dehumidifier 
spends in different operating modes, DOE investigated studies of 
dehumidifier usage patterns. Table III.4 shows estimates of monthly 
dehumidifier usage obtained from a variety of sources, including a 1998 
Arthur D. Little (ADL) report,\18\ a 2005 Lawrence Berkeley National 
Laboratory (LBNL) report,\19\ and estimates provided by ENERGY

[[Page 75307]]

STAR \20\ and AHAM in 2006 \21\ in consultation with manufacturers and 
others familiar with the product. Most of these estimates demonstrate 
heavy dehumidifier usage during the summer months and none between the 
months of November and March. DOE proposes to use AHAM's mid-level 
estimate of active mode hours for the purpose of this analysis. The 
AHAM data were developed based on manufacturer experience. DOE 
believes, therefore, that the data represent a reasonable assessment of 
the average usage patterns for dehumidifiers. As shown in Table III.4, 
AHAM's mid-level estimate of annual hourly operation is 1,095 active 
mode hours, while other estimates range from 875 to 4,320 active mode 
hours. For the purposes of this analysis, DOE proposes that 1,095 hours 
be associated with active mode.

    DOE is aware that a dehumidifier may be unplugged for a certain 
percentage of time, and, therefore, will not be in either standby mode 
or off mode. DOE does not have data regarding the amount of time a 
typical dehumidifier is unplugged. However, in its comment on the 
framework document for the residential dishwasher, dehumidifier, 
cooking products, and commercial clothes washer energy conservation 
standards rulemaking, AHAM stated that dehumidifiers are normally used 
on a regional basis in basements during humid summer hours in northern 
climates. Reviewing the survey data presented in Table III.4, which 
show no active mode hours of operation for the months from November to 
March and minimal active mode hours in April, in the context of AHAM's 
comment has led DOE to tentatively conclude that dehumidifiers would 
likely be unplugged during the period from November to March and for 
half of April (5.5 months). Therefore, DOE estimates the time 
dehumidifiers spend unplugged as 3,984 hours.
    Next, DOE investigated how the remaining 3,681 non-active hours 
(8,760-1,095--3,984) would be allocated to the other operating modes. 
DOE is not aware of any reliable consumer usage data on the number of 
hours per year dehumidifiers spend in delay start and bucket full/
removed modes. In the absence of such data, DOE estimated the time 
spent in these modes in the manner described below.
    To estimate a representative number of annual hours for bucket 
full/removed mode, DOE estimated the number of times a dehumidifier 
bucket would be expected to fill with water and the number of hours the 
bucket would be expected to remain full before being emptied. As 
discussed in the November 2007 ANOPR, DOE estimated that the 
predominant dehumidifier product class, which has 25.01-35 pints per 
day capacity and operates at the existing energy conservation standard 
level (EF of 1.35 liters per kWh), would have an annual energy use of 
about 480 kWh per year. 72 FR 64432, 64473 (Nov. 15, 2007). DOE 
estimates that such a dehumidifier would remove 648 liters of water 
from the air per year (480 kWh per year x 1.35 liters per kWh = 648 
liters per year). Based on the units in DOE's test sample with a 
capacity between 25.01-35 pints per day, DOE estimates that the average 
condensate collection bucket size for this product class would be 18.7 
pints, or 8.9 liters.\22\ If it is assumed the typical consumer will 
run a dehumidifier until the bucket is full before emptying it, DOE 
estimates that dehumidifiers will reach bucket full/removed mode 73 
times per year (648 liters of water removed from the air per year/8.9 
liter bucket capacity = 73). Thus, the 1095 active mode hours divided 
by 73 bucket full mode events results in an estimate of 15 hours that 
the dehumidifier spends in active mode per bucket fill. DOE believes 
that consumers will not empty the collection bucket more than once per 
day, so the dehumidifier is likely to remain full an average of 9 hours 
per bucket-full event (24 hours per day - 15 hours per bucket fill = 9 
hours). Based on these assumptions, DOE estimates the number of bucket 
full/removed annual hours to be 657 hours (73 bucket fills per year x 9 
hours bucket remains full before being emptied and replaced).

4 in the docket for this rulemaking
---------------------------------------------------------------------------

    To determine the number of annual hours associated with delay start 
mode, DOE surveyed dehumidifier models available on the market. DOE 
determined that about 19 percent of dehumidifiers have a delay start 
mode function and that the delay start function can be set for up to 24 
hours. DOE estimates that the delay start function will only be used on 
50 percent of these 19 percent of dehumidifiers that have the function. 
DOE also estimates that consumers that do use the delay start function 
will use it once a day for 10 percent of the 199 dehumidifying days per 
year. (The dehumidifying days are the 6.5 months of the year during 
which the dehumidifier may be operated in active mode, as shown in the 
AHAM's mid-level estimate in Table III.4.) DOE also estimates that 
consumers will use an average delay setting of 12 hours (which is half 
of the maximum delay start time available on dehumidifiers.) Based on 
these assumptions, DOE estimates that the average time a dehumidifier 
is operating in delay start mode per active mode day is 6.8 minutes, or 
23 hours per year.
    The estimates of annual hours and energy consumption associated 
with the active, delay start, and bucket full/removed modes are 
displayed in Table III.5. To determine the approximate wattages 
associated with standby modes and off mode, DOE conducted internal 
testing on 13 dehumidifiers.\23\ Average power levels in watts are 
multiplied by

[[Page 75308]]

the estimated number of hours allocated per year to each mode to 
calculate the annual energy use for each mode. For the purpose of this 
analysis, DOE estimated that the remaining 3,001 annual hours (3,681 
non-active mode hours - 23 delay start mode hours - 657 bucket/full 
removed mode hours = 3,001 hours) would be split between off-cycle 
mode, inactive mode, and off mode. The split between these three modes 
is discussed later in this section.

  which the delay start function is used) x 10 percent (for consumers that use the delay start function, the
  percentage of dehumidifying days that a consumer will use this function per day) x 12 hours (average
  programmed duration of delay start period) x 199 days (number of dehumidifying days per year) = 23 hours.
** 73 (bucket fills per year) x 9 hours (hours the bucket remains full before being emptied and replaced) = 657
  hours.

    As discussed in section III.C, DOE believes that delay start mode 
would not be considered part of standby mode, but instead would be a 
form of active mode. Therefore, DOE is not proposing amendments to the 
dehumidifier test procedure to define ``delay start mode'' or to 
measure power consumption in this mode. The comparison of the annual 
energy consumption of different dehumidifier modes presented in Table 
III.5 shows that energy use associated with delay start mode is 
relatively insignificant because dehumidifiers spend only a small 
number of hours in this mode. In addition, the power levels in delay 
start mode are similar to those for off/inactive modes for 
dehumidifiers currently on the market. Therefore, DOE proposes to 
allocate delay start mode hours (which total 23 hours for this example 
case) to the off-cycle, inactive, and off modes (which would then total 
3,024 hours in this example case).
    To determine the annual hours per mode for dehumidifiers for which 
not all standby modes are possible, DOE estimated values by 
reallocating the hours associated with various standby modes that are 
not present using the ratios discussed previously. DOE's logic for this 
distribution of hours follows.
    For example, if bucket full/removed mode is not possible for 
dehumidifiers with a continuous drain and no condensate collection 
bucket, off-cycle/inactive/off modes would equal 3,024 off-cycle/
inactive/off mode hours + 657 bucket full/removed hours = 3,681 hours. 
DOE believes the proposed definition of ``off mode'' as applied to 
dehumidifiers is similar to that for dishwashers. Off mode, as applied 
to dehumidifiers, refers to units with mechanical rather than 
electronic controls, or units with electronic controls combined with a 
mechanical switch that the user can use to de-energize the electronic 
controls. DOE observed during testing that dehumidifiers with 
electronic controls require that a humidity level be set when the unit 
is powered on; if the room humidity level is above the level set, the 
unit begins operating in active mode. Therefore, DOE believes that when 
a dehumidifier with electronic controls is powered on, the majority of 
the non-active mode hours (i.e., when the relative humidity level in 
the room is below the dehumidifier humidity set point) would be 
associated with off-cycle mode. If a dehumidifier is equipped with 
electronic controls and a push-button sensor to power on the controls, 
it operates in the inactive mode when the unit is not powered on. DOE 
believes that a dehumidifier with a remote control can be controlled 
whenever it is plugged in. Thus, these units do not have an off mode 
and instead operate in the inactive mode when the unit is not powered 
on, and operate in off-cycle or active mode when the unit is powered 
on. However, if a dehumidifier allows the user to switch off remote 
control operation, it would be capable of off, inactive, and off-cycle 
modes. DOE does not have consumer usage data on the distribution of 
annual mode hours for dehumidifiers among the different combinations of 
off-cycle, inactive, and off modes. DOE proposes that the annual hours 
be split evenly between the off-cycle, inactive, and off modes 
depending on which modes are present on the dehumidifier under test. 
Otherwise, for units which are capable of operating in only off-cycle, 
inactive, or off mode, DOE proposes that all of the hours be allocated 
to the appropriate mode. DOE welcomes any data available on this issue.
    In summary, DOE proposes to amend the dehumidifier test procedure 
to determine energy use associated with standby mode and off mode by: 
(1) Calculating the products of wattage and allocated hours for all 
possible standby and off modes; (2) summing the results; and (3) 
dividing the sum by 1,000 to convert from Wh to kWh. DOE invites 
comments on this proposed methodology for dehumidifiers and associated 
factors, including accuracy, allocation of annual hours, and test 
burden. DOE may also consider adoption in the final rule of the 
following alternative methodology based on comments received.
    The comparison of annual energy use of different dehumidifier modes 
shows that, for dehumidifiers currently on the market, power 
consumption levels in bucket full/removed mode are distinct from but 
comparable to those for off-cycle/inactive/off modes. Thus, DOE could 
adopt an approach for dehumidifiers limited to specifying the hours for 
only off-cycle, inactive, and off modes when calculating energy use 
associated with standby mode and off mode. In that case, all of the 
non-active hours (3,681 hours total), including bucket full/removed 
mode, would be allocated to the off-cycle, inactive, and off modes. DOE 
invites comment on whether this alternative would be representative of 
the standby mode and off mode power consumption of dehumidifiers 
currently on the market.
3. Conventional Cooking Products
    Energy use for conventional cooking products is expressed as EF, 
which is the ratio of annual cooking energy output to the annual energy 
input. As discussed in section III.F, DOE has determined it is 
technically feasible to incorporate measures of standby mode and off 
mode energy use into the overall energy use metric, and accordingly, 
DOE is making a proposal consistent with that determination, as 
required by the EISA 2007 amendments to EPCA. (42 U.S.C. 
6295(gg)(2)(A)) In order to incorporate standby mode and off mode power 
consumption into the overall energy consumption for conventional

[[Page 75309]]

cooking products, DOE analyzed data on the usage patterns and power 
consumption in these modes on an annual basis for each product class of 
conventional cooking products, as discussed below.
a. Conventional Ovens
    DOE investigated the hours and energy consumption associated with 
each possible operating mode for conventional ovens, including 
inactive, Sabbath, delay start, cycle finished, off, and active modes.
    DOE is unaware of reliable consumer usage data for the number of 
hours spent in active mode for conventional ovens. To estimate the 
number of annual active mode hours, DOE reviewed data from the Energy 
Information Administration (EIA)'s 2005 ``Residential Energy 
Consumption Survey'' (RECS).\24\ RECS is a national sample survey of 
housing units that collects statistical information on the consumption 
of and expenditures for energy in housing units, along with data on 
energy-related characteristics of the housing units and occupants. RECS 
provides survey data on the frequency of conventional oven use per 
week. Based on its analysis of RECS data, DOE estimates that the number 
of active mode cooking cycles per year is 211. Assuming that a 
conventional oven active mode cycle is on average 1 hour long, DOE 
estimates that the number of active mode hours per year for a 
conventional oven is 211. DOE welcomes information and data on such 
average cycle times, as well as the number of annual conventional oven 
usage cycles. For the purposes of this analysis, DOE proposes that 211 
hours be associated with active mode and the remaining 8,549 hours of 
the year be associated with the remaining possible modes, including 
inactive, delay start, cycle finished, Sabbath, and off mode. RECS also 
provides consumer usage data on how many conventional ovens are used 
per household. Based on its analysis of RECS data, DOE estimates that 
1.04 conventional ovens are used per household.

Administration, ``Residential Energy Consumption Survey,'' 2005 
Public Use Data Files (2005). Available online at: http://www.eia.doe.gov/emeu/recs/. It is noted that EIA's 2005 RECS is the 
latest available version of this survey.
---------------------------------------------------------------------------

    Similarly, DOE is not aware of reliable consumer usage data for the 
number of hours conventional ovens spend in various non-active modes. 
DOE estimated the time associated with Sabbath mode in conventional 
ovens based on the percentage of Jewish households in the United States 
that observe kosher practices at home (the households most likely to 
use Sabbath mode), the number of annual work-free days, and the number 
of conventional ovens used per household. DOE believes this represents 
the population of consumers which uses Sabbath mode features in a 
conventional oven. DOE estimates the percentage of Jewish consumers 
observing kosher practices at home to be about 0.54 percent of the 
total U.S. population, based on data from a 2000-01 population survey 
by the United Jewish Communities,\25\ which reported that 21 percent of 
2.9 million Jewish households (which equals 609,000 households) in the 
United States keep a kosher home, compared to 112,386,298 total 
households in the United States as of 2008.\26\ DOE also estimates 
1,584 hours of annual work-free hours, which would comprise the weekly 
Sabbath and the annual non-working Jewish holidays.\27\ Using these 
estimates as well as the number of ovens per household as determined 
earlier in this section, DOE estimates that 8.9 hours per year would be 
associated with Sabbath mode for conventional ovens. The calculation 
is: 0.54 percent (percent of U.S. households that observe kosher 
practices) x 1,584 hours (annual work-free hours per year) x 1.04 
(conventional ovens per household) = 8.9 hours per year.

---------------------------------------------------------------------------

    DOE also estimated the annual hours associated with delay start 
mode. DOE analyzed data from a DOE survey of ovens currently available 
on the market and estimated that 96 percent of conventional ovens are 
equipped with a delay start function. DOE notes that conventional ovens 
may offer a delay start function of up to 24 hours. However, DOE is 
unaware of any reliable usage data for the delay start function. In the 
absence of data, DOE has estimated that, given the prevalence of delay 
start-equipped ovens, approximately 50 percent of consumers will use 
this feature for at least some cooking cycles. DOE further estimates 
that consumers that use the delay start function will use it for 5 
percent of cooking cycles and will program a 12-hour delay start 
period. (The 12-hour delay is half of the maximum delay start time 
available on conventional ovens, which is also approximately the time 
between preparation in the morning and initiating a cooking cycle in 
the evening.) Applying these estimates to all conventional ovens and 
cooking cycles (211 cycles per year as determined earlier), DOE 
estimates that the average time a conventional oven is operating in 
delay start mode per cycle is 17 minutes, or 61 hours per year.
    To estimate the annual time associated with cycle finished mode, 
DOE assumed that conventional ovens on average remain in cycle finished 
mode for 5 minutes after every cycle. Calculations based on that 
assumptions result in an estimate of 18 annual hours associated with 
cycle finished mode.
    The remaining 8,461.1 annual hours not associated with active, 
Sabbath, delay start, or cycle finished mode are allocated to off and 
inactive modes (8,760 annual hours - 211 active mode hours - 8.9 
Sabbath mode hours - 61 delay start mode hours - 18 cycle finished mode 
hours). The hours for the relevant modes and estimates of power input 
and energy use for conventional ovens are summarized in Table III.6. 
The approximate wattages associated with each mode, other than active 
mode, were determined from internal testing conducted by DOE on 12 
conventional ovens.\28\ For active mode, the typical average power 
level is calculated by dividing the annual energy consumption of a 
baseline efficiency model electric self-cleaning oven (EF of 0.1099 and 
annual energy consumption of 171.0 kWh per year) by 211 active hours, 
which equals 810 W. Electric self-cleaning ovens were determined to be 
the predominant conventional electric oven product class as part of the 
November 2007 ANOPR. 72 FR 64432, 64474 (Nov. 15, 2007). Although the 
hours per mode presented in Table III.6 are estimates based on limited 
study data, DOE believes the energy patterns illustrated in this table 
are representative for most conventional ovens.

----------------------------------------------------------------------------------------------------------------
* 1,584 (yearly work-free hours) x 1.04 (conventional ovens per household) x 0.54 percent (percent of U.S.
  households that observe kosher practices) = 8.9 hours.
** 96 percent (percentage of conventional ovens with delay start function) x 50 percent (percentage of machines
  for which the delay start function is used) x 5 percent (for consumers that use the delay start function, the
  percentage of cycles that the consumer would use this function) x 12 hours (average programmed duration of
  delay start period) x 211 (annual cooking cycles) = 61 hours.
[dagger] 211 (annual cycles) x 5 minutes (estimated cycle finished minutes per cycle) = 18 hours.

    As discussed in section III.C, DOE believes delay start mode would 
not be considered part of standby mode, but instead, it would be a form 
of active mode. Therefore, DOE is not proposing amendments to the 
conventional oven test procedure to define delay start mode or to 
measure power consumption in this mode. The comparison of annual energy 
consumption of different conventional oven modes shows that energy use 
associated with delay start mode is relatively insignificant because 
only a small number of hours are associated with this mode. In 
addition, the power levels in this mode are similar to those for off/
inactive modes for conventional ovens currently on the market. For this 
reason, DOE proposes to allocate delay start mode hours (which total 61 
hours for this example case) to the inactive and off modes (which would 
then total 8,522.1 hours in this example case.)
    As also discussed in section III.C, DOE believes that Sabbath mode 
would be considered part of the active mode. Therefore, DOE is not 
proposing amendments to the conventional cooking products test 
procedure to define ``Sabbath mode'' or to measure power consumption in 
this mode. However, the comparison of annual energy consumption shows 
that energy use associated with Sabbath mode is insignificant because 
only a small number of hours are associated with this mode. DOE 
proposes to allocate the Sabbath mode hours (which total 8.9 hours for 
this example case) to the active mode (which would then total 219.9 
hours in this example case.)
    To determine the annual hours per mode for conventional ovens for 
which not all standby modes are possible, DOE estimated values based 
upon reallocating the hours for modes that are not present using the 
ratios discussed previously. If cycle finished mode, which is assumed 
to be a fixed value of 18 hours per year, is not present, the off/
inactive mode hours would be 8,760 total hours - 219.9 active mode 
hours = 8,540.1 hours. If cycle finished mode is possible, the off/
inactive mode hours would be 8,760 total hours - 219.9 active mode 
hours - 18 cycle finished hours = 8,522.1 hours.
    DOE believes the proposed definition of ``off mode'' as applied to 
conventional ovens refers to units with mechanical rather than 
electronic controls, or units with electronic controls combined with a 
mechanical switch, with which the user can de-energize the electronic 
controls. Reactivating a conventional oven with a push-button sensor, 
touch sensor, or other similar device that consumes power is considered 
to be a standby mode feature under the proposed definitions. DOE 
believes there are few conventional ovens with electronic controls that 
have an additional mechanical off switch. Therefore, the combined 
inactive/off mode hours would most likely be allocated fully either to 
inactive or off mode, depending on the type of controls present on the 
conventional oven. DOE does not have market share information to 
determine how many conventional ovens are currently shipped with 
electromechanical controls. For conventional ovens with electronic 
controls plus a mechanical off switch, DOE proposes to allocate half of 
the non-active hours to inactive and half to off modes. DOE welcomes 
comment and additional information on this point, and on the proposed 
approach for calculating energy use for standby mode and off mode, 
including the decision to allocate all non-active mode hours to off and 
inactive modes.
    In summary, DOE proposes to determine conventional oven energy use 
associated with standby mode and off mode by: (1) Calculating the 
product of wattage and allocated hours for all possible standby and off 
modes; (2) summing the results; and (3) dividing the sum by 1,000 to 
convert from Wh to kWh. DOE invites comments on this proposed 
methodology and associated factors, including accuracy, allocation of 
annual hours, and test burden. DOE may also consider adoption in the 
final rule of the following alternative methodology based on comments 
received.
    The comparison of annual energy use of different conventional oven 
product modes shows that cycle finished mode represents a relatively 
small number of hours at a low power consumption level. For 
conventional ovens currently on the market, these levels are distinct 
from but comparable to those for off/inactive mode. Thus, DOE could 
adopt an approach that would be limited to specifying the hours for 
only off/inactive mode when calculating energy use associated with 
standby and inactive/off modes. In that case, all of the non-active 
hours (8,540.1 hours total) would be allocated to the inactive/off 
mode. DOE invites comment on whether such an alternative would be 
representative of the standby mode and off mode power consumption of 
conventional ovens currently on the market.
b. Conventional Cooktops
    DOE investigated the hours and energy consumption associated with 
each possible operating mode for conventional cooktops, including 
inactive, Sabbath, off, and active modes. DOE did not observe any 
models capable of delay start mode or cycle finished mode, and, 
therefore DOE did not consider these modes for the purpose of this 
analysis.
    DOE notes that RECS only provides usage data for conventional ovens 
and does not provide usage data for conventional cooktops. As discussed 
earlier, DOE estimated based on the 2005 RECS that there are 211 active 
mode cooking cycles per year for conventional ovens, resulting in 211 
active mode hours per year, and that the

[[Page 75311]]

balance of the year (8,549 hours) is the established number of hours 
associated with Sabbath, cycle finished, and off/inactive modes. DOE 
believes that conventional cooktops would have similar active mode 
usage patterns as conventional ovens. Therefore, DOE is proposing to 
use the same 211 active mode cycles per year and annual active mode 
hours for conventional cooktops, so the remaining 8,549 hours of the 
year would be associated with standby mode and off mode. DOE welcomes 
information and data on such average cycle times, as well as annual 
conventional cooktop usage. DOE also notes that RECS does not provide 
usage data on how many conventional cooktops are used per household. As 
a result, DOE is proposing to estimate that the average household uses 
one conventional cooktop.
    DOE is not aware of reliable consumer usage data for hours spent in 
different standby and off modes in conventional cooktops. As was done 
for conventional ovens, DOE estimated the time associated with Sabbath 
mode in conventional cooktops based on the percentage of Jewish 
households in the United States that observe kosher practices at home 
(the households most likely to use Sabbath mode), the number of annual 
work-free days, and the number of conventional cooktops used per 
household. As it did for conventional ovens, DOE estimates that about 
0.54 percent of U.S. households keep kosher homes and that there are 
approximately 1,584 annual work-free hours (i.e., the weekly Sabbath 
and the annual Jewish holidays). Applying these estimates to the number 
of cooktops per household as estimated earlier in this section, and 
estimating that, based on the relatively few cooktop models certified 
as Sabbath-compliant \29\ and the greater availability of ovens with a 
dedicated Sabbath mode that DOE estimates would be used in place of 
cooktops on the Sabbath at least 75 percent of the time, DOE estimates 
that 2.1 hours per year would be associated with Sabbath mode for 
conventional cooktops. The calculation is as follows: 0.54 percent 
(percent of U.S. households that observe kosher practices) x 1,584 
hours (annual work-free hours per year) x 1 (conventional cooktops per 
household) x 25 percent (percent of times that cooktops would be used 
on the Sabbath in place of or in addition to using an oven) = 2.1 hours 
per year.
---------------------------------------------------------------------------

    \29\ For information on requirements for Sabbath-compliant 
cooktops and a list of cooktops certified as Sabbath-compliant, 
please visit: http://www.star-k.com/cons-appl.htm.
---------------------------------------------------------------------------

    The remaining 8,546.9 annual hours not associated with active or 
Sabbath mode are allocated to off and inactive modes (8,760 annual 
hours - 211 active mode hours - 2.1 Sabbath mode hours). The hours for 
the relevant modes and estimates of power input and energy are 
summarized in Table III.7. The approximate wattage associated with off/
inactive mode was determined from internal testing conducted by DOE on 
eight conventional cooktops.\30\ For active mode, the typical average 
power level is calculated by dividing the annual energy consumption of 
a baseline efficiency model electric smooth cooktop (EF of 0.742 and 
annual energy consumption of 128.2 kWh per year) by 211 active hours 
which equals 608 W. Electric smooth cooktops were determined to be the 
predominant conventional electric cooktop product class as part of the 
November 2007 ANOPR. (See the ANOPR national impacts analysis (NIA) 
spreadsheet tool for cooktops and ovens on DOE's Web site at: http://www1.eere.energy.gov/buildings/appliance_standards/residential/cooking_products_anopr_tools.html). For Sabbath mode, in which the 
cooktop burners or heating elements must not be turned on, off, or 
adjusted during the Sabbath period, DOE estimates that the burners will 
be set at no more than 25 percent of the heating input associated with 
active mode, due to safety considerations during such long-duration 
use. Although the hours per mode presented in this table are estimates 
based on limited study data, DOE believes that energy patterns 
illustrated in this table are representative for most conventional 
cooktops, because Sabbath mode hours would be a small percentage of 
annual hours and the off/inactive power levels are based on DOE test 
measurements.

----------------------------------------------------------------------------------------------------------------
* 1,584 (yearly work-free hours) x 1 (conventional cooktops per household) x 0.54 percent (percent of U.S.
  households that observe kosher practices) x 25 percent (percent of times that cooktops would be used on the
  Sabbath in place of or in addition to using an oven) = 2.1 hours.
** 608 W (power in active mode) x 25 percent (percent of heating input that would be used during the Sabbath).

    For the same reasons as discussed for conventional ovens, DOE 
believes that Sabbath mode would be considered part of the active mode. 
Therefore, DOE is not proposing amendments to the conventional cooktop 
test procedure to define ``Sabbath mode'' or to measure power 
consumption. However, the comparison of annual energy consumption shows 
that energy use associated with Sabbath mode is insignificant, because 
only a small number of hours are associated with this mode. DOE instead 
proposes to allocate the Sabbath mode hours (which total 2.1 hours for 
this example case) to the active mode (which would total 213.2 hours in 
this example case).
    As with conventional ovens, DOE believes there are few conventional 
cooktops with electronic controls that have an additional mechanical 
off switch. Therefore, DOE proposes that the combined inactive/off mode 
hours would likely be allocated fully either to inactive or off mode, 
depending on the type of controls present on the conventional cooktop. 
For conventional cooktops for which both inactive mode and off mode are 
present, DOE proposes to allocate half of the non-active hours each to 
inactive and off modes. DOE welcomes comment and additional information 
on the proposed approach for calculating energy use for standby and off 
modes, including the decision to allocate all non-active mode hours to 
off and inactive modes.
    In summary, DOE proposes to determine conventional cooktop energy 
use associated with standby mode and off mode by: (1) Calculating the 
product

[[Page 75312]]

of wattage and allocated hours for all possible standby and off modes; 
(2) summing the results; and (3) dividing the sum by 1,000 to convert 
from Wh to kWh. DOE invites comments on this proposed methodology and 
associated factors, including accuracy, allocation of annual hours, and 
test burden.
c. Conventional Ranges
    DOE investigated the hours and energy consumption associated with 
each possible operating mode for conventional ovens, including 
inactive, Sabbath, delay start, cycle finished, off, and active mode.
    DOE notes that RECS only provides usage data for conventional ovens 
and does not provide usage data for conventional ranges. As discussed 
previously, DOE estimated based on the 2005 RECS that there are 211 
active mode cooking cycles per year for conventional ovens, resulting 
in 211 active mode hours per year. DOE also estimated that a 
conventional cooktop is in the active mode for 211 hours per year. DOE 
believes that the annual hours that a conventional range would be in 
active mode would be the sum of the annual active mode hours for 
conventional ovens and cooktops, which equals 422 hours. Since a range 
is essentially a combination of an oven and a cooktop, DOE's rationale 
is to combine the average values for these two components individually. 
Therefore, for conventional ranges, DOE proposes to associate 422 hours 
with active mode, and the remaining 8,338 hours of the year with the 
other non-active modes. DOE welcomes information and data on such 
average cycle times, as well as annual conventional range usage. RECS 
does provide consumer usage data on how many conventional ranges are 
used per household. Based on its analysis of the 2005 RECS data, DOE 
estimates that 1.03 conventional ranges are used per household.
    DOE is not aware of reliable consumer usage data for hours spent in 
different standby and off modes for conventional ranges. DOE estimated 
the time associated with Sabbath mode in conventional ranges based on 
the percentage of Jewish households in the United States that observe 
kosher practices at home (the households expected to use Sabbath mode), 
the number of annual work-free days, and the number of conventional 
ranges used per household. DOE believes this represents the population 
of consumers which uses Sabbath mode features in a conventional range. 
As was determined earlier for conventional ovens, DOE estimates that 
about 0.54 percent of U.S. households keep kosher homes. As was 
estimated for conventional ovens, DOE estimates 1,584 annual work-free 
hours (i.e., the weekly Sabbath and the annual Jewish holidays). 
Applying these estimates to the number of ranges per household, as 
estimated earlier in this section, DOE estimates that 8.8 hours per 
year would be associated with Sabbath mode for conventional ranges. The 
calculation is as follows: 0.54 percent (percent of U.S. households 
that observe kosher practices) x 1,584 hours (annual work-free hours 
per year) x 1.03 (conventional ranges per household) = 8.8 hours per 
year.
    DOE analyzed a DOE survey of ranges currently available on the 
market and estimated that 79 percent of conventional ranges are 
equipped with a delay start function.\31\ DOE notes that conventional 
ranges available on the market may offer a delay start function of up 
to 24 hours. As it did for conventional ovens, DOE estimates this 
function will be used on only 50 percent of conventional ranges so 
equipped. DOE also estimates that consumers who use the delay start 
function will use it for 5 percent of the cooking cycles associated 
with the oven portion of the range and set it for a 12-hour delay start 
period. (The 12-hour period is half of the maximum delay start time 
available on conventional ranges.) Applying these estimates to all 
conventional ranges and applying DOE's estimate of 211 oven cooking 
cycles per year, DOE estimates that the average time a conventional 
range is operating in delay start mode per cycle is 14.2 minutes, or 
(14.2 minutes x 211 cycles per year) = 50 hours per year.
---------------------------------------------------------------------------

    \31\ See ``Range Modes.pdf,'' included as entry No. 5 in the 
docket for this rulemaking.
---------------------------------------------------------------------------

    To estimate the annual time associated with cycle finished mode, 
DOE assumes that, on average, conventional ranges remain in cycle 
finished mode for 5 minutes after every cycle, resulting in (5 minutes 
x 211 cycles per year) = 18 annual hours associated with cycle finished 
mode.
    The remaining 8,261.2 annual hours not associated with active, 
Sabbath, delay start, or cycle finished mode are allocated to off and 
inactive modes (8,760 annual hours - 422 active mode hours - 8.8 
Sabbath mode hours - 50 delay start mode hours - 18 cycle finished mode 
hours). The hours for the relevant modes and estimates of power input 
and energy use are summarized in Table III.8. The approximate wattages 
associated with each mode, other than active mode, were determined from 
internal testing conducted by DOE on 21 conventional ranges.\32\ For 
active mode, the typical average power level is based on the sum of the 
typical power levels for conventional ovens and cooktops, as shown in 
Table III.6 and Table III.7. While the hours per mode presented in this 
table are estimates based on limited study data, DOE believes that 
energy patterns illustrated in Table III.8 are representative for most 
conventional ranges because Sabbath mode hours would be reasonably a 
small percentage of annual hours and the non-active power levels are 
based on DOE test measurements.

** 79 percent (percentage of conventional ovens with delay start function) x 50 percent (percentage of machines
  for which the delay start function is used) x 5 percent (for consumers that use the delay start function, the
  percentage of cycles that the consumer would use this function) x 12 hours (average programmed duration of
  delay start period) x 211 (annual oven portion cooking cycles) = 50 hours.
[dagger] 211 (annual oven portion cooking cycles) x 5 minutes (estimated cycle finished minutes per cycle) = 18
  hours.
[dagger][dagger] 171 kWh (annual energy use for conventional ovens) + 128.2 kWh (annual energy use for
  conventional cooktops) = 299.2 kWh.

    As discussed for conventional ovens, DOE believes delay start mode 
would not be considered part of standby mode, because it is not a mode 
which may persist indefinitely. Instead, DOE believes delay start mode 
to be a form of active mode. Therefore, DOE is not proposing amendments 
to the conventional range test procedure to define ``delay start mode'' 
or to measure power consumption in this mode. However, the comparison 
of annual energy consumption of different conventional oven ranges 
shows that energy use associated with delay start mode is relatively 
insignificant because only a small number of hours are associated with 
this mode. In addition, the power levels in this mode are similar to 
those for off/inactive modes for conventional ranges currently on the 
market. For this reason, DOE proposes to allocate delay start mode 
hours (which total 50 hours for this example case) to the inactive and 
off modes (which would then total 8,367.5 hours in this example case).
    Also, as discussed for conventional ovens, DOE believes that 
Sabbath mode would be considered part of the active mode for 
conventional ranges because, in this mode, the automatic shutoff for 
the oven is overridden to allow for warming of pre-cooked foods during 
such periods as the Jewish Sabbath. Therefore, DOE is not proposing 
amendments to the conventional cooking products test procedure to 
define ``Sabbath mode'' or to measure power consumption in this mode. 
However, the comparison of annual energy consumption shows that energy 
use associated with Sabbath mode is insignificant because only a small 
number of hours are associated with this mode. DOE instead proposes to 
allocate the Sabbath mode hours (which total 8.8 hours for this example 
case) to the active mode hours (which would then total 430.8 hours in 
this example case.)
    To determine the annual hours per mode for conventional ranges for 
which not all standby modes are possible, DOE estimated values by 
reallocating the hours for modes that are not present using the 
allocations discussed previously. If cycle finished mode, which is 
assumed to be a fixed value of 18 hours per year, is not possible, the 
off/inactive mode hours would be 8,760 total hours - 430.8 active mode 
hours = 8,329.2 hours. If cycle finished mode is possible, the off/
inactive mode hours would be 8,760 total hours - 430.8 active mode 
hours - 18 cycle finished hours = 8,311.2 hours.
    Also, for the same reasons as discussed for conventional ovens, DOE 
proposes that, in most cases, the combined inactive/off mode hours 
would be allocated fully either to inactive or off mode, depending on 
the type of controls present on the conventional range. However, for 
conventional ranges for which both inactive mode and off mode are 
present, DOE proposes to allocate half of the non-active hours to 
inactive mode and the other half to off mode. DOE welcomes comment and 
additional information on the proposed approach for calculating energy 
use for standby mode and off mode, including the decision to allocate 
all non-active mode hours to off and inactive modes.
    In summary, DOE proposes to determine conventional range energy use 
associated with standby mode and off mode by: (1) Calculating the 
product of wattage and allocated hours for all possible standby and off 
modes; (2) summing the results; and (3) dividing the sum by 1,000 to 
convert from Wh to kWh. DOE invites comments on this proposed 
methodology and associated factors, including accuracy, allocation of 
annual hours, and test burden. DOE may also consider adoption in the 
final rule of the following alternative methodology based on comments 
received.
    The comparison of annual energy use of different conventional range 
modes shows that cycle finished mode represents a relatively small 
number of hours at a low power consumption level. For conventional 
ranges currently on the market, these levels are distinct from but 
comparable to those for off/inactive mode. Thus, DOE could adopt an 
approach that would be limited to specifying the hours for only off/
inactive mode when calculating energy use associated with standby and 
inactive/off modes. In that case, all of the non-active hours (8,329.2 
hours total) would be allocated to the inactive/off mode. DOE invites 
comment on whether such an alternative would be representative of the 
standby mode and off mode power consumption of conventional ranges 
currently on the market.

F. Measures of Energy Consumption

    Under 42 U.S.C. 6295(gg)(2)(A), EPCA directs that when DOE amends 
its test procedures to include standby mode and off mode energy 
consumption for a covered product, DOE shall integrate such energy 
consumption into the overall energy efficiency, energy consumption, or 
other energy descriptor for each covered product, unless the Secretary 
determines that: (i) The current test procedures for a covered product 
already fully account for and incorporate the standby mode and off mode 
energy consumption of the covered product; or (ii) such an integrated 
test procedure is technically infeasible for a particular covered 
product, in which case the Secretary shall prescribe a separate standby 
mode and off mode energy use test procedure, if technically feasible.
    In considering whether it is technically feasible to integrate 
standby mode and off mode energy use into a combined metric along with 
active mode energy use, DOE makes a case-by-case determination for the 
product in question. One general principle which DOE considers in 
making such determination is whether any mode of energy use would be so 
large as to overwhelm the other for standard-setting purposes. Although 
it may be possible to measure energy use in each mode with a 
substantial degree of precision, in some cases there may be very large 
differences in energy use in active mode versus standby/off modes, such 
that the effects of the lesser mode would not be reflected within the 
precision of the regulatory metric. In such cases, DOE believes that 
disparities in levels of energy use between the different modes may be 
so great that a combined metric would not be technically feasible, so a 
separate metric for standby mode and off mode would be warranted. In 
contrast, where the standby mode and off mode energy use is of a 
magnitude that it would materially affect that standard-setting process 
without overwhelming the effects of differing levels of active mode 
energy use, a combined metric would be meaningful and will be adopted 
as required by the EISA 2007 amendments to EPCA.
    DOE analyzed whether the existing measures of energy consumption 
for dishwashers, dehumidifiers, and conventional cooking products can 
be

combined with standby mode and off mode energy use to form a single 
metric. DOE's tentative conclusions resulting from this inquiry are 
presented below.
1. Dishwashers
    The DOE test procedure for dishwashers currently incorporates 
various measures of energy and water consumption. These include per-
cycle machine electrical energy consumption, per-cycle energy 
consumption from drying dishes after termination of the last rinse 
cycle, per-cycle water consumption, per-cycle water heating energy 
consumption (for electrically-heated, gas-heated, or oil-heated water), 
and annual standby energy consumption. (See 10 CFR part 430, subpart B, 
appendix C, sections 5.1, 5.2, 5.4, and 5.6 for details.) The test 
procedure also provides a calculation for EAEU, EAOC, and EF. The 
current standards are based on EAEU, which incorporates a simplified 
measure of standby energy consumption. (10 CFR 430.32(f)(2))
    Because the dishwasher test procedure already combines measures of 
active mode energy consumption and standby mode energy use to derive an 
overall ``energy efficiency measure,'' DOE believes it is technically 
feasible to incorporate standby mode and off mode energy consumption 
into the overall energy efficiency descriptor, which is the EAEU. 
Furthermore, DOE notes that the analysis of overall energy use for 
dishwashers presented in section III.E shows that the standby mode and 
off mode energy use is of a magnitude that it would materially affect 
that standard-setting process without overwhelming the effects of 
differing levels of active mode energy use . Therefore, a combined 
measure of energy efficiency for dishwashers is a meaningful measure. 
As discussed in section III.B, DOE is proposing amendments to the 
testing methods to fully account for standby mode and off mode energy 
consumption for dishwashers. Because it is proposing those amendments, 
DOE also proposes to amend the calculation of EAEU to incorporate the 
revised measures of standby mode and off mode energy consumption. The 
revised EAEU metric would satisfy the EPCA requirement to integrate 
standby mode and off mode energy consumption into the overall energy 
consumption metric. (42 U.S.C. 6295(gg)(2)(A))
    As noted in section I, EPCA requires that DOE must determine to 
what extent, if any, a proposed test procedure would alter the measured 
energy efficiency of any covered product as determined under the 
existing test procedure. (42 U.S.C. 6293(e)(1)) The current DOE 
dishwasher test procedure defines ``standby mode'' as the ``lowest 
power consumption mode which cannot be switched off or influenced by 
the user * * *'' 10 CFR part 430, subpart B, appendix C, section 1.14. 
DOE is proposing to measure an additional standby mode (i.e., cycle 
finished mode). However, the proposed amendments would clarify that the 
provisions related to the new measures of energy consumption in standby 
mode and off mode would not be required to be used by manufacturers 
until the compliance date of any amended dishwasher standards 
addressing standby mode and off mode energy use. Therefore, the 
proposed amendments to the dishwasher test procedure regarding standby 
mode and off mode would not alter the measured efficiency of any 
covered product under the existing test procedure.
    As part of the final rule for the DOE dishwasher test procedure 
published in the Federal Register on August 29, 2003, DOE also revised 
the test procedure to include standby energy use in the EAOC 
calculation, and DOE notes that this amendment was supported by 
interested parties. 68 FR 51887, 51892-93. Because the current 
dishwasher test procedure already incorporates standby energy use in 
the EAOC, DOE believes that it is technically feasible to incorporate 
both standby mode and off mode energy use into the EAOC. Therefore, DOE 
proposes to amend the EAOC calculation to incorporate the revised 
measures of standby mode and off mode energy consumption.
    The current dishwasher test procedure also includes a calculation 
of EF. EF is expressed in cycles per kWh and equals the inverse of the 
per-cycle machine electrical energy consumption minus half of the 
drying energy consumption.\33\ DOE notes that the current EF metric 
does not include standby mode energy use. For the final rule amending 
the dishwasher test procedure published on August 29, 2003, DOE amended 
only the EAEU and EAOC calculations to include standby power 
consumption. DOE did not include standby power consumption in the EF 
calculation because, as defined in the test procedure, the EF: (1) 
Represents the amount of energy used during a cycle, and (2) standby 
power is energy consumed outside the wash cycle of a dishwasher and is, 
therefore, not a parameter in the EF calculation. 68 FR 51887, 51893. 
For these same reasons, and because the existing energy conservation 
standard is based on EAEU, DOE is not proposing changes to the EF 
calculation to include standby mode and off mode energy consumption. 
DOE expects that the annual energy use metric would continue to be the 
basis for energy conservation standards when they are next amended.
---------------------------------------------------------------------------

    \33\ The drying energy consumption for dishwashers is the energy 
consumed using the power-dry feature after the termination of the 
last rinse option of the normal cycle.
---------------------------------------------------------------------------

    The dishwasher test procedure currently provides instructions for 
rounding EAOC to the nearest dollar per year. 10 CFR 430.23(c)(1). 
However, no instructions are provided for rounding the final values of 
EF, EAEU, or water consumption per cycle (the latter two of which are 
the metrics for the current dishwasher energy conservation standards), 
nor the contributory measurements and interim calculations. This lack 
of specificity for rounding may lead to uncertainty in the reported 
metrics or to discrepancies among test laboratories for the same 
product, resulting in difficulty for regulated entities to ascertain, 
certify, and report compliance with the existing standards. Therefore, 
DOE proposes to add instructions to 10 CFR 430.23(c) requiring that EF 
be rounded to two decimal places, water consumption be rounded to one 
decimal place, and EAEU be rounded to the nearest whole kWh/year.
2. Dehumidifiers
    The DOE test procedure for dehumidifiers currently only 
incorporates energy consumption in the form of EF (see 10 CFR part 430, 
subpart B, appendix X for details). EF, defined as liters of water 
removed from the air per kWh, is the metric for the current energy 
conservation standards for dehumidifiers. (10 CFR 430.32(v)) The 
current DOE test procedure for dehumidifiers does not account for 
standby mode and off mode energy use.
    As directed by EPCA, DOE analyzed whether standby mode and off mode 
energy consumption could be integrated into the overall energy 
efficiency metric. (42 U.S.C. 6295(gg)(2)(A)) DOE notes that the 
analysis of overall energy use for dehumidifiers presented in section 
III.E indicates the standby mode and off mode energy use is of a 
magnitude that it would materially affect that standard-setting process 
without overwhelming the effects of differing levels of active mode 
energy use. Therefore, a combined measure of energy efficiency for 
dehumidifiers is a meaningful measure.
    DOE proposes to establish the following measure of energy 
consumption for dehumidifiers. The integrated energy factor (IEF) 
measure accounts for the product's energy use in

[[Page 75315]]

standby mode and off mode, as well as the energy use of the product's 
main functions. As discussed earlier, the current EF associated with 
dehumidifiers is calculated based on the liters of water removed from 
the air per kWh of energy consumed, as measured by a 24-hour test 
cycle. 10 CFR part 430, subpart B, appendix X, section 4. DOE notes 
that the calculation of EF represents the liters of water removed from 
the air per kWh of energy consumed over a given period of time, such as 
the number of active mode hours per year. If the ratio of the annual 
standby mode and off mode hours to the annual active mode hours is used 
to apportion standby mode and off mode power consumption over the 
active mode test period of one day, it is possible to calculate an IEF 
that incorporates both the efficiency of water removal from the air and 
the standby mode and off mode energy consumption. DOE proposes to 
calculate IEF using the following calculation: (The liters of water 
removed over the active mode test cycle)/((the active mode energy 
consumption over the active mode test cycle) + ((the standby mode and 
off mode annual energy consumption \34\ x 24 hours)/(the active mode 
hours per year))).
---------------------------------------------------------------------------

    \34\ The standby mode and off mode annual energy consumption is 
equivalent to the average standby mode and off mode power multiplied 
by the number of standby mode and off mode hours per year.
---------------------------------------------------------------------------

    Section 3 of the current dehumidifier test procedure provides 
instructions for rounding EF to two decimal places. Section 3 also 
states that measurements be recorded at the resolution of the test 
instrumentation, and that calculations be rounded off to the same 
number of significant digits as the previous step. 10 CFR part 30, 
subpart B, appendix X. DOE is proposing to retain these same 
instructions for EF in section 3.1 of the amended test procedure. DOE 
is also proposing to round the IEF value in section 5.2 to two decimal 
places.
3. Conventional Cooking Products
    The DOE test procedures for conventional cooking tops, ovens, and 
ranges currently incorporate various measures of energy consumption. 
These include test energy consumption, annual cooking energy 
consumption, annual energy consumption of any continuously-burning 
pilot lights, annual self-cleaning energy consumption, annual clock 
energy consumption, total annual energy consumption, and cooking 
efficiency. (See 10 CFR part 430, subpart B, appendix I for details.) 
The test procedure also provides a calculation for EF \35\ and EAOC. 
Although there are no current energy conservation standards based on 
performance for conventional cooking products (see 10 CFR 430.32(j)), 
historically, DOE's rulemaking analyses when considering standards have 
used EF as the energy conservation metric for conventional cooking 
products.
---------------------------------------------------------------------------

    \35\ ``Energy factor'' is defined as the ratio of the annual 
useful energy output to the total annual energy input.
---------------------------------------------------------------------------

    DOE notes that the conventional cooking products test procedure 
currently combines measures of energy consumption and narrow forms of 
standby energy use, including continuously-operating clock and gas 
standing pilot light energy consumption, to derive an overall ``energy 
efficiency measure.'' Therefore, a combined measure of energy 
efficiency for conventional cooking products has already been 
demonstrated to be a workable and meaningful measure. For this reason, 
DOE believes that it would be technically feasible to incorporate 
standby mode and off mode energy consumption into the overall energy 
efficiency descriptor (i.e., EF). Because DOE is proposing amendments 
to fully account for standby mode and off mode energy consumption for 
conventional cooking products, DOE proposes a combined metric 
addressing active, standby, and off modes for conventional cooking 
products, as explained in further detail below.
    DOE proposes to establish the following measures of energy 
consumption for conventional ovens. The measures integrate the 
product's energy use in standby mode and off mode with energy use 
during main functions of the products. For conventional electric ovens, 
the ``integrated annual energy consumption'' will be defined as the sum 
of the annual standby mode and off mode energy consumption, annual 
primary cooking energy consumption, and annual primary self-cleaning 
energy consumption, expressed in kWh. For conventional gas ovens that 
use electrical energy, the ``integrated annual electrical energy 
consumption'' will be defined as the sum of the annual standby mode and 
off mode energy consumption, annual secondary cooking energy 
consumption,\36\ and annual secondary self-cleaning energy consumption, 
expressed in kWh. For conventional electric ovens, IEF will be defined 
as the (annual useful cooking energy output)/(integrated annual energy 
consumption). For conventional gas ovens, IEF will be defined as the 
(annual useful cooking energy output)/(annual gas energy consumption + 
integrated annual electrical energy consumption). DOE also proposes to 
include similar integrated annual energy consumption and IEF metrics 
for section 4.1.2.6 of the cooking products test procedure regarding 
multiple conventional ovens (i.e., cooking appliances that include more 
than one conventional oven).
---------------------------------------------------------------------------

    \36\ ``Secondary cooking energy consumption'' includes any 
electrical energy consumption of a conventional gas cooking product 
during active mode operation.
---------------------------------------------------------------------------

    DOE proposes to establish the following measures of energy 
consumption for conventional cooktops. The measures integrate the 
product's energy use in standby mode and off mode with energy use 
during the main functions of the products. For conventional electric 
cooktops, the ``integrated annual energy consumption'' will be defined 
as the (annual standby mode and off mode energy consumption) + (annual 
useful cooking energy output/conventional cooktop cooking efficiency), 
expressed in kWh. For conventional gas cooktops, the ``integrated 
annual electrical energy consumption'' will be defined as the sum of 
the annual standby mode and off mode energy consumption, annual energy 
consumption for cooking, and annual energy consumption of the gas 
standing pilot light, expressed in kWh. For conventional electric 
cooktops, IEF will be defined as the annual useful cooking energy 
output divided by the electric cooktop integrated annual energy 
consumption. For conventional gas cooktops, IEF will be defined as the 
annual useful cooking energy output divided by the gas cooktop 
integrated annual energy consumption.
    DOE proposes to establish the following measures of energy 
consumption for conventional kitchen ranges (i.e., a cooktop and oven 
combined). The measures integrate the product's energy use in standby 
mode and off mode with energy use during the main functions of the 
products. ``Integrated annual energy consumption'' shall be the sum of 
the annual cooking energy consumption of each of its components plus 
the conventional range annual standby mode and off mode energy 
consumption.\37\ The IEF of a

[[Page 75316]]

kitchen range shall be the sum of the annual useful cooking energy 
output of each component divided by the sum of the integrated annual 
energy consumption of each component.
---------------------------------------------------------------------------

    \37\ DOE proposes to measure the standby mode and off mode 
energy consumption for a conventional range as a single product and 
to add the standby mode and off mode energy consumption separately 
in the calculation of the integrated annual energy consumption. It 
proposes this so that the standby mode and off mode power 
consumption is not measured separately for each component (i.e., 
cooktop and oven) and then summed with the cooking annual energy 
consumption, which would effectively double count the contribution 
of standby mode and off mode energy consumption.
---------------------------------------------------------------------------

    DOE is also proposing to amend the estimated annual energy cost 
calculations in 10 CFR 430.23(i) to include the cost of energy consumed 
in standby mode and off mode for conventional cooking products because, 
as noted above, the current cooking products test procedure already 
incorporates measures of narrow forms of standby energy use in the 
EAOC. Thus, DOE believes that it is technically feasible to incorporate 
both standby mode and off mode energy use into the EAOC and proposes to 
amend the EAOC calculations to incorporate the revised measures of 
standby mode and off mode energy consumption, thereby more accurately 
representing the unit's EAOC.
    The cooking products test procedure currently provides instructions 
for rounding EAOC to the nearest dollar per year, and the cooking 
efficiency and energy factor to three significant digits. 10 CFR 
430.23(i)(1), (2), (4). DOE proposes to amend the test procedure to 
provide similar instructions requiring that EAOC based on total 
integrated annual electrical energy consumption be rounded to the 
nearest dollar per year and IEF to three significant digits.

G. Compliance With Other EPCA Requirements

1. Test Burden
    As noted previously, under 42 U.S.C. 6293(b)(3), EPCA requires that 
``[a]ny test procedures prescribed or amended under this section shall 
be reasonably designed to produce test results which measure energy 
efficiency, energy use * * * or estimated annual operating cost of a 
covered product during a representative average use cycle or period of 
use * * * and shall not be unduly burdensome to conduct.'' For the 
reasons that follow, DOE has tentatively concluded that amending the 
relevant DOE test procedures to incorporate clauses regarding test 
conditions and methods found in IEC Standard 62301 (First Edition), 
along with the proposed modifications, would produce the required test 
results and would not result in any undue burdens.
    The proposed amendments to the DOE test procedures incorporate a 
test standard that is accepted internationally for measuring power 
consumption in standby mode and off mode. Based on its analysis of IEC 
Standard 62301 (First Edition), IEC Standard 62301 (CDV), and IEC 
Standard 62301 (FDIS), DOE has determined that the proposed amendments 
to the residential dishwashers, dehumidifiers, and conventional cooking 
products test procedures will produce standby mode and off mode average 
power consumption measurements that are representative of an average 
use cycle. These measures will be representative both when the measured 
power is stable and when it is unstable (i.e., when the measured power 
varies by 5 percent or more during the proposed 30-minute stabilization 
period.) Also, the test methods and equipment that the amendments would 
require for measuring standby mode and off mode power in these products 
are not substantially different from the test methods and equipment 
required in the current DOE tests. Thus, the proposed test procedure 
amendments would not require manufacturers to make significant 
investments in test facilities and new equipment. Therefore, DOE has 
tentatively concluded that the amended test procedures would produce 
test results that measure the standby mode and off mode power 
consumption during representative use, and that the test procedure 
would not be unduly burdensome to conduct.
2. Potential Incorporation of IEC Standard 62087
    Under 42 U.S.C. 6295(gg)(2)(A), EPCA directs DOE to consider IEC 
Standard 62087 when amending test procedures to include standby mode 
and off mode power measurements. As discussed in section III.C of this 
notice, DOE reviewed IEC Standard 62087, ``Methods of measurement for 
the power consumption of audio, video, and related equipment'' (Second 
Edition 2008-09), and has tentatively determined that it would not be 
applicable to measuring power consumption of electrical appliances such 
as dishwashers, dehumidifiers, and conventional cooking products. 
Therefore, DOE has tentatively concluded that referencing IEC Standard 
62087 is not necessary for the proposed amendments to the test 
procedures that are the subject of this rulemaking.
3. Integration of Standby Mode and Off Mode Energy Consumption Into the 
Efficiency Metrics
    Under 42 U.S.C. 6295(gg)(2)(A), EPCA requires that standby mode and 
off mode energy consumption be ``integrated into the overall energy 
efficiency, energy consumption, or other energy descriptor for each 
covered product'' unless the current test procedures already fully 
account for the standby mode and off mode energy consumption or if such 
an integrated test procedure is technically infeasible. For 
dishwashers, DOE proposes to incorporate the standby mode and off mode 
energy consumption into the test procedure's calculation of ``estimated 
annual energy use'' and ``estimated annual operating cost,'' as 
discussed in section III.F. For dehumidifiers, DOE proposes to 
incorporate the standby mode and off mode energy consumption into an 
IEF metric, as discussed in section III.F. For conventional cooking 
products, DOE proposes to incorporate the standby mode and off mode 
energy consumption into an ``integrated annual energy consumption,'' an 
IEF, and ``estimated annual operating cost,'' as discussed in section 
III.F of this notice.
    EPCA further provides that test procedure amendments adopted to 
comply with the new statutory requirements for standby mode and off 
mode energy consumption shall not be used to determine compliance with 
previously established standards. (42 U.S.C. 6295(gg)(2)(C)) Under this 
provision, the test procedure amendments pertaining to standby mode and 
off mode energy consumption that DOE proposes to adopt in this 
rulemaking would not apply to, and would have no impact on, existing 
standards.
    Even though 42 U.S.C. 6295(gg)(2)(C) clearly states that the test 
procedure amendments for measurement of standby mode and off mode 
energy consumption shall not apply to existing standards, DOE must 
nonetheless determine the effect of such test procedure amendments on 
measured energy efficiency, measured energy use, or measured water use 
of any covered product, pursuant to 42 U.S.C. 6293(e)(1). This analysis 
is provided below. However, no amendments to the energy conservation 
standards will be required pursuant to 42 U.S.C. 6293(e)(2), because 
such test procedure amendments will not impact the existing energy 
conservation standards until the compliance date of a subsequent final 
rule that amends the standard to comprehensively address standby mode 
and off mode energy consumption.
    For dishwashers, the current energy conservation standards are 
based on EAEU, which includes standby mode power consumption. Because 
today's proposed amendments would revise the calculations for EAEU and 
EAOC, both of which currently incorporate standby mode power to a 
limited extent, DOE investigated how the proposed amendments would 
affect the product's

[[Page 75317]]

measured efficiency. DOE believes the proposed changes to the 
dishwasher testing methods for measuring standby mode and off mode 
energy consumption do not vary significantly from the methods currently 
in the DOE test procedure for measuring standby power and would not 
alter the measured efficiency. DOE also believes that the proposed 
revision to the definition of ``standby mode'' would be unlikely to 
significantly affect the measured efficiency. Therefore, DOE believes 
that the proposed amendments to the dishwasher test procedure would not 
alter the measured efficiency. In addition, because the proposed 
amendments would clarify that manufacturers would not be required to 
use the provisions relating to standby mode and off mode energy use in 
the EAEU to determine compliance with the energy conservation standard 
until the compliance date of new dishwasher standard addressing standby 
mode and off mode energy use, the proposed test procedure amendments 
would not affect a manufacturer's ability to demonstrate compliance 
with previously established standards for dishwashers.
    For dehumidifiers, existing energy conservation standards are based 
on EF, which would not be altered by the proposed test procedure 
amendments. In addition, DOE notes that the new combined measure of 
energy consumption (i.e., the integrated energy factor) which it is 
proposing would not affect the existing standard. However, the test 
procedure's amended provisions for standby mode and off mode would be a 
requirement for demonstrating compliance with DOE's energy conservation 
standards upon the effective date of a subsequent standards rulemaking 
for dehumidifiers that accounts for standby mode and off mode power 
consumption. Thus, the proposed test procedure amendments for 
dehumidifiers comply with these EPCA requirements.
    The current energy conservation standards for conventional cooking 
products are prescriptive standards which ban standing pilot lights. 
There are no current performance-based Federal energy conservation 
standards for conventional cooking products (including energy use in 
standby mode and off mode). Even so, the new combined measure of energy 
consumption (i.e., the integrated annual energy consumption) which DOE 
is proposing would not affect the existing annual energy consumption or 
EF metrics. The cooking products test procedure's amended provisions 
for standby mode and off mode would be a requirement for demonstrating 
compliance with any new performance-based energy conservation standards 
upon the effective date of a subsequent standards rulemaking for 
conventional cooking products that accounts for standby mode and off 
mode power consumption. Thus, the proposed test procedure amendments 
for cooking products would not impact a manufacturer's ability to 
certify compliance with existing requirements and, accordingly, comply 
with these EPCA requirements.

H. Impact of the Proposed Amendments on EnergyGuide and ENERGY STAR

    DOE considered potential impacts of the proposed test procedure 
amendments to the Federal Trade Commission (FTC) EnergyGuide 
requirements and to the U.S. Environmental Protection Agency (EPA)/DOE 
ENERGY STAR voluntary labeling program and determined that there will 
be no impact. For dishwashers, the primary indication of energy use 
provided in the EnergyGuide label is EAEU and EAOC. In addition, the 
ENERGY STAR program for dishwashers is based on the EAEU and water 
consumption. As discussed in section III.G, DOE has clarified that the 
proposed amended calculations for dishwasher EAEU and EAOC shall be 
used for purposes other than demonstrating compliance with existing 
energy conservation standards, including the EnergyGuide and ENERGY 
STAR programs. Because, as also discussed in section III.G, the changes 
in EAEU and EAOC due to the proposed amendments are expected to be 
insignificant, DOE believes that there will be no measurable impact on 
these programs. For dehumidifiers, there are currently no FTC 
EnergyGuide labeling requirements, and the ENERGY STAR program is based 
on EF, which will not be changed by the proposed amendments. For 
conventional cooking products, there is currently no FTC EnergyGuide 
labeling requirement or ENERGY STAR voluntary labeling program.

IV. Procedural Issues and Regulatory Review

A. Review Under Executive Order 12866

    Today's proposed rule action is not a ``significant regulatory 
action'' under section 3(f) of Executive Order 12866, ``Regulatory 
Planning and Review,'' 58 FR 51735 (Oct. 4, 1993). Accordingly, this 
proposed action was not subject to review under the Executive Order by 
the Office of Information and Regulatory Affairs (OIRA) in the Office 
of Management and Budget (OMB).

B. Review Under the Regulatory Flexibility Act

    The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires 
preparation of an initial regulatory flexibility analysis for any rule 
that by law must be proposed for public comment, unless the agency 
certifies that the proposed rule, if promulgated, will not have a 
significant economic impact on a substantial number of small entities. 
As required by Executive Order 13272, ``Proper Consideration of Small 
Entities in Agency Rulemaking,'' 67 FR 53461 (August 16, 2002), DOE 
published procedures and policies on February 19, 2003, to ensure that 
the potential impacts of its rules on small entities are properly 
considered during the rulemaking process. 68 FR 7990. DOE's procedures 
and policies may be viewed on the Office of the General Counsel's Web 
site (http://www.gc.doe.gov).
    DOE reviewed today's proposed rule under the provisions of the 
Regulatory Flexibility Act and the procedures and policies published on 
February 19, 2003. The proposed rule would prescribe test procedure 
amendments that would be used to determine compliance with energy 
conservation standards for the products that are the subject of this 
rulemaking.
    The Small Business Administration (SBA) considers a business entity 
to be a small business, if, together with its affiliates, it employs 
less than a threshold number of workers specified in 13 CFR part 121. 
The threshold values set forth in these regulations use size standards 
and codes established by the North American Industry Classification 
System (NAICS) that are available at: http://www.sba.gov/idc/groups/public/documents/sba_homepage/serv_sstd_tablepdf.pdf. The threshold 
number for NAICS classification code 335228, titled ``Other Major 
Household Appliance Manufacturing,'' is 500 employees; this 
classification specifically includes residential dishwasher 
manufacturers. Additionally, the threshold number for NAICS 
classification code 335211, titled ``Electric Housewares and Household 
Fan Manufacturing,'' is 750 employees; this classification specifically 
includes manufacturers of residential dehumidifiers. Finally, the 
threshold number for NAICS classification code 335221, titled 
``Household Cooking Appliance Manufacturing,'' is 750 employees; this 
classification specifically includes manufacturers of residential 
conventional cooking products.
    Most of the manufacturers supplying residential dishwashers, 
dehumidifiers,

[[Page 75318]]

and/or conventional cooking products are large multinational 
corporations. DOE surveyed the AHAM member directory to identify 
manufacturers of residential dishwashers, dehumidifiers, and 
conventional cooking products. DOE then consulted publicly-available 
data, purchased company reports from vendors such as Dun and 
Bradstreet, and contacted manufacturers, where needed, to determine if 
they meet the SBA's definition of a ``small business manufacturing 
facility'' and have their manufacturing facilities located within the 
United States. Based on this analysis, DOE estimates that there are two 
small businesses that manufacture conventional cooking products and no 
small businesses that manufacture dishwashers or dehumidifiers.
    For the reasons stated in the preamble, DOE has tentatively 
concluded that the proposed rule would not have a significant impact on 
either small or large manufacturers under the applicable provisions of 
the Regulatory Flexibility Act. The proposed rule would amend DOE's 
test procedures for dishwashers, dehumidifiers, and conventional 
cooking products by incorporating testing provisions to address standby 
mode and off mode energy consumption that will be used to develop and 
test compliance with future energy conservation standards. The test 
procedure amendments involve measuring power input when the dishwasher, 
dehumidifier, or conventional cooking product is in standby mode and 
off mode. These tests can be conducted in the same facilities used for 
the current energy testing of these products, but could also be 
conducted in separate facilities consisting of little more than 
temperature-controlled space, so there would be no additional 
facilities costs required by the proposed rule. In addition, while the 
power meter required for these tests might require greater accuracy 
than the power meter used for current energy testing, the investment 
required for a possible instrumentation upgrade would likely be 
relatively modest. It is possible that the manufacturers, or their 
testing facilities, already have equipment that meets the requirements 
of IEC Standard 62301, but an Internet search of equipment that 
specifically meets the requirements of IEC Standard 62301 reveals a 
cost of approximately $2,700 to $3,000. This cost is small compared to 
the overall financial investment needed to undertake the business 
enterprise of testing consumer products which involves facilities, 
qualified staff, and specialized equipment.
    Furthermore, the duration of the standby mode and off mode testing 
is generally not expected to exceed the time required to conduct 
current energy testing. The requirements for equipment and time 
necessary to conduct the additional proposed tests are not expected to 
impose a significant economic burden on entities subject to the 
applicable testing requirements.
    For these reasons, DOE tentatively concludes and certifies that the 
proposed rule would not have a significant economic impact on a 
substantial number of small entities. Accordingly, DOE has not prepared 
a regulatory flexibility analysis for this rulemaking. DOE will 
transmit the certification and supporting statement of factual basis to 
the Chief Counsel for Advocacy of the SBA for review under 5 U.S.C. 
605(b).

C. Review Under the Paperwork Reduction Act of 1995

    This rule contains a collection-of-information requirement subject 
to the Paperwork Reduction Act (PRA) which has been approved by OMB 
under Control Number 1910-1400. Public reporting burden for compliance 
reporting for energy and water conservation standards is estimated to 
average 30 hours per response, including the time for reviewing 
instructions, searching existing data sources, gathering and 
maintaining the data needed, and completing and reviewing the 
collection of information. Send comments regarding this burden 
estimate, or any other aspect of this data collection, including 
suggestions for reducing the burden, to DOE (see ADDRESSES) and by e-
mail to [email protected].
    Notwithstanding any other provision of the law, no person is 
required to respond to, nor shall any person be subject to a penalty 
for failure to comply with, a collection of information subject to the 
requirements of the PRA, unless that collection of information displays 
a currently valid OMB Control Number.

D. Review Under the National Environmental Policy Act of 1969

    In this rulemaking, DOE proposes test procedure amendments that it 
expects would be used to develop and implement future energy 
conservation standards for residential dishwashers, dehumidifiers, and 
conventional cooking products. DOE has determined that this rule falls 
into a class of actions that are categorically excluded from review 
under the National Environmental Policy Act of 1969 (42 U.S.C. 4321 et 
seq.) and DOE's implementing regulations at 10 CFR part 1021. 
Specifically, this proposed rule would amend the existing test 
procedures for these products without changing their environmental 
effects, and, therefore, it is covered by the Categorical Exclusion in 
10 CFR part 1021, subpart D, paragraph A5, which applies because this 
rule would establish revisions to existing test procedures that would 
not affect the amount, quality, or distribution of energy usage, and, 
therefore, would not result in any environmental impacts. Accordingly, 
neither an environmental assessment nor an environmental impact 
statement is required.

E. Review Under Executive Order 13132

    Executive Order 13132, ``Federalism,'' imposes certain requirements 
on agencies formulating and implementing policies or regulations that 
preempt State law or that have Federalism implications. 64 FR 43255 
(August 10, 1999). The Executive Order requires agencies to examine the 
constitutional and statutory authority supporting any action that would 
limit the policymaking discretion of the States, and to carefully 
assess the necessity for such actions. The Executive Order also 
requires agencies to have an accountable process to ensure meaningful 
and timely input by State and local officials in the development of 
regulatory policies that have Federalism implications. On March 14, 
2000, DOE published a statement of policy describing the 
intergovernmental consultation process that it will follow in 
developing such regulations. 65 FR 13735. DOE has examined this 
proposed rule and determined that it would not have a substantial 
direct effect on the States, on the relationship between the national 
government and the States, or on the distribution of power and 
responsibilities among the various levels of government. EPCA governs 
and prescribes Federal preemption of State regulations as to energy 
conservation for the products that are the subject of today's proposed 
rule. States can petition DOE for exemption from such preemption to the 
extent, and based upon criteria, set forth in EPCA. (42 U.S.C. 6297(d)) 
Therefore, Executive Order 13132 requires no further action.

F. Review Under Executive Order 12988

    Regarding the review of existing regulations and the promulgation 
of new regulations, section 3(a) of Executive Order 12988, ``Civil 
Justice Reform,'' 61 FR 4729 (Feb. 7, 1996), imposes on Federal 
agencies the general duty to adhere to the following requirements: (1) 
Eliminate drafting errors and ambiguity; (2) write

[[Page 75319]]

regulations to minimize litigation; (3) provide a clear legal standard 
for affected conduct rather than a general standard; and (4) promote 
simplification and burden reduction. Section 3(b) of Executive Order 
12988 specifically requires that Executive agencies make every 
reasonable effort to ensure that the regulation clearly specifies the 
following: (1) The preemptive effect, if any; (2) any effect on 
existing Federal law or regulation; (3) a clear legal standard for 
affected conduct while promoting simplification and burden reduction; 
(4) the retroactive effect, if any; (5) definitions of key terms; and 
(6) other important issues affecting clarity and general draftsmanship 
under any guidelines issued by the Attorney General. Section 3(c) of 
Executive Order 12988 requires Executive agencies to review regulations 
in light of applicable standards in sections 3(a) and 3(b) to determine 
whether they are met or whether it is unreasonable to meet one or more 
of them. DOE has completed the required review and determined that, to 
the extent permitted by law, this proposed rule meets the relevant 
standards of Executive Order 12988.

G. Review Under the Unfunded Mandates Reform Act of 1995

    Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) (Pub. 
L. 104-4; 2 U.S.C. 1501 et seq.) requires each Federal agency to assess 
the effects of Federal regulatory actions on State, local, and Tribal 
governments and the private sector. For a proposed regulatory action 
likely to result in a rule that may cause the expenditure by State, 
local, and Tribal governments, in the aggregate, or by the private 
sector, of $100 million or more in any one year (adjusted annually for 
inflation), section 202 of UMRA requires a Federal agency to publish 
estimates of the resulting costs, benefits, and other effects on the 
national economy. (2 U.S.C. 1532(a), (b)) UMRA also requires a Federal 
agency to develop an effective process to permit timely input by 
elected officers of State, local, and Tribal governments on a proposed 
``significant intergovernmental mandate,'' and requires an agency plan 
for giving notice and opportunity for timely input to potentially 
affected small governments before establishing any requirements that 
might significantly or uniquely affect such governments. On March 18, 
1997, DOE published a statement of policy on its process for 
intergovernmental consultation under UMRA. 62 FR 12820. (The policy is 
also available at http://www.gc.doe.gov.) Today's proposed rule 
contains neither an intergovernmental mandate nor a mandate that may 
result in an expenditure of $100 million or more in any year, so these 
requirements do not apply.

H. Review Under the Treasury and General Government Appropriations Act, 
1999

    Section 654 of the Treasury and General Government Appropriations 
Act, 1999 (Pub. L. 105-277) requires Federal agencies to issue a Family 
Policymaking Assessment for any rule that may affect family well-being. 
Today's proposed rule would not have any impact on the autonomy or 
integrity of the family as an institution. Accordingly, DOE has 
concluded that it is not necessary to prepare a Family Policymaking 
Assessment.

I. Review Under Executive Order 12630

    Pursuant to Executive Order 12630, ``Governmental Actions and 
Interference with Constitutionally Protected Property Rights,'' 53 FR 
8859 (March 18, 1988), DOE has determined that this proposed regulation 
would not result in any takings that might require compensation under 
the Fifth Amendment to the U.S. Constitution.

J. Review Under the Treasury and General Government Appropriations Act, 
2001

    Section 515 of the Treasury and General Government Appropriations 
Act, 2001 (Pub. L. 106-554; 44 U.S.C. 3516 note) provides for agencies 
to review most disseminations of information to the public under 
guidelines established by each agency pursuant to general guidelines 
issued by OMB. OMB's guidelines were published at 67 FR 8452 (Feb. 22, 
2002), and DOE's guidelines were published at 67 FR 62446 (Oct. 7, 
2002). DOE has reviewed today's notice under the OMB and DOE guidelines 
and has concluded that it is consistent with applicable policies in 
those guidelines.

K. Review Under Executive Order 13211

    Executive Order 13211, ``Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use,'' 66 FR 28355 
(May 22, 2001), requires Federal agencies to prepare and submit to OIRA 
a Statement of Energy Effects for any proposed significant energy 
action. A ``significant energy action'' is defined as any action by an 
agency that promulgates or is expected to lead to promulgation of a 
final rule, and that: (1) Is a significant regulatory action under 
Executive Order 12866, or any successor order; and (2) is likely to 
have a significant adverse effect on the supply, distribution, or use 
of energy; or (3) is designated by the Administrator of OIRA as a 
significant energy action. For any proposed significant energy action, 
the agency must give a detailed statement of any adverse effects on 
energy supply, distribution, or use if the proposal is implemented, and 
of reasonable alternatives to the action and their expected benefits on 
energy supply, distribution, and use. Today's proposed regulatory 
action to amend the test procedures for residential dishwashers, 
dehumidifiers, and conventional cooking products to address standby 
mode and off mode energy use is not a significant regulatory action 
under Executive Order 12866 or any successor order. It would not have a 
significant adverse effect on the supply, distribution, or use of 
energy. Moreover, it has not been designated by the Administrator of 
OIRA as a significant energy action. Therefore, it is not a significant 
energy action, and, accordingly, DOE has not prepared a Statement of 
Energy Effects.

L. Review Under Section 32 of the Federal Energy Administration Act of 
1974

    Under section 301 of the DOE Organization Act (Pub. L. 95-91; 42 
U.S.C. 7101 et seq.), DOE must comply with section 32 of the Federal 
Energy Administration Act of 1974, as amended by the Federal Energy 
Administration Authorization Act of 1977 (FEAA). (15 U.S.C. 788) 
Section 32 essentially provides that, where a proposed rule authorizes 
or requires use of commercial standards, the rulemaking must inform the 
public of the use and background of such standards. In addition, 
section 32(c) requires DOE to consult with the Attorney General and the 
Chairman of the Federal Trade Commission (FTC) concerning the impact of 
the commercial or industry standards on competition.
    The proposed modifications to test procedures addressed by this 
proposed rule incorporate testing methods contained in the commercial 
standard, IEC Standard 62301 ``Household electrical appliances--
Measurement of standby power.'' DOE has evaluated this standard and is 
unable to conclude whether it fully complies with the requirements of 
section 32(b) of the FEAA (i.e., whether it was developed in a manner 
that fully provides for public participation, comment, and review). DOE 
will consult with the Attorney General and the Chairman of the FTC 
about the impact on competition of using the methods contained in this 
standard before prescribing a final rule.

C. Conduct of the Public Meeting

    DOE will designate a DOE official to preside at the public meeting 
and may also use a professional facilitator to aid discussion. The 
meeting will not be a judicial or evidentiary-type public hearing, but 
DOE will conduct it in accordance with section 336 of EPCA (42 U.S.C. 
6306). There shall not be discussion of proprietary information, costs 
or prices, market share, or other commercial matters regulated by U.S. 
anti-trust laws. A court reporter will be present to record the 
proceedings and prepare a transcript.
    The public meeting will be conducted in an informal, conference 
style. DOE reserves the right to schedule the order of presentations 
and to establish the procedures governing the conduct of the public 
meeting. DOE will present summaries of comments received before the 
public meeting, allow time for presentations by participants, and 
encourage all interested parties to share their views on issues 
affecting this rulemaking. Each participant will be allowed to make a 
prepared general statement (within time limits determined by DOE), 
before the discussion of specific topics. DOE will permit other 
participants to comment briefly on any general statements. At the end 
of all prepared statements on each specific topic, DOE will permit 
participants to clarify their statements briefly and comment on 
statements made by others.
    Participants should be prepared to answer DOE's and other 
participants' questions. DOE representatives may also ask participants 
about other matters relevant to this rulemaking. The official 
conducting the public meeting will accept additional comments or 
questions from those attending, as time permits. The presiding official 
will announce any further procedural rules or modification of these 
procedures that may be needed for the proper conduct of the public 
meeting. After the public meeting, interested parties may submit 
further comments on the proceedings as well as on any aspect of the 
rulemaking until the end of the comment period.
    DOE will make the entire record of this proposed rulemaking, 
including the transcript from the public meeting, available for 
inspection at the U.S. Department of Energy, 6th Floor, 950 L'Enfant 
Plaza, SW., Washington, DC 20024, (202) 586-2945, between 9 a.m. and 4 
p.m., Monday through Friday, except Federal holidays. Copies of the 
transcript will be posted on the DOE Web site and will also be 
available for purchase from the transcribing reporter.

D. Submission of Comments

    DOE will accept comments, data, and information regarding the 
proposed rule before or after the public meeting, but no later than the 
date provided at the beginning of this notice. Comments, data, and 
information submitted to DOE's e-mail address for this rulemaking 
should be provided in WordPerfect, Microsoft Word, PDF, or text (ASCII) 
file format. Stakeholders should avoid the use of special characters or 
any form of encryption, and wherever possible, comments should include 
the electronic signature of the author. Comments, data, and information 
submitted to DOE via mail or hand delivery/courier should include one 
signed paper original. No telefacsimiles (faxes) will be accepted.
    Pursuant to 10 CFR 1004.11, any person submitting information that 
he or she believes to be confidential and exempt by law from public 
disclosure should submit two copies: One copy of the document that 
includes all of the information believed to be confidential, and one 
copy of the document with that information deleted. DOE will make its 
own determination as to the confidential status of the information and 
treat it accordingly.
    Factors of interest to DOE when evaluating requests to treat 
submitted information as confidential include: (1) A description of the 
items; (2) whether and why such items are customarily treated as 
confidential within the industry; (3) whether the information is 
generally known by or available from other sources; (4) whether the 
information was previously made available to others without obligation 
concerning its confidentiality; (5) an explanation of the competitive 
injury to the submitting person that would result from public 
disclosure; (6) when such information might lose its confidential 
character due to the passage of time; and (7) why disclosure of the 
information would be contrary to the public interest.

E. Issues on Which DOE Seeks Comment

    Although comments are welcome on all aspects of this rulemaking, 
DOE is particularly interested in receiving comments and views of 
interested parties on the following issues:
    1. Incorporation of IEC Standard 62301 (First Edition). DOE invites 
comment on the adequacy of IEC Standard 62301 (First Edition) to 
measure standby mode and off mode power consumption for residential 
dishwashers, dehumidifiers, and conventional cooking products, and the 
suitability of incorporating into DOE regulations the following 
specific provisions from IEC Standard 62301 (First Edition): section 4 
(``General conditions for measurements''), paragraph 4.2, ``Test 
room,'' paragraph 4.4, ``Supply voltage waveform,'' and paragraph 4.5, 
``Power measurement accuracy,'' and section 5 (``Measurements''), 
paragraph 5.1, ``General,'' and paragraph 5.3, ``Procedure.'' (See 
section III.B)
    2. Mode definitions. DOE welcomes comment on the proposed 
definitions of

[[Page 75321]]

``standby mode,'' ``off mode,'' and ``active mode,'' which are based on 
the definitions provided in IEC Standard 62301 (FDIS). (See section 
III.C)
    3. Dishwasher standby and off modes. DOE invites comment on the 
proposed establishment of inactive mode and cycle finished mode as 
standby modes for dishwashers and the determination that ``delay start 
mode'' would not be considered a standby mode. DOE further invites 
comment as to whether there are any modes consistent with the ``active 
mode,'' ``standby mode,'' or ``off mode'' definitions that have not 
been identified in this NOPR and the extent to which these modes would 
represent significant energy use. (See section III.C)
    4. Dehumidifier standby and off modes. DOE invites comment on the 
proposed establishment of inactive mode, off-cycle mode, and bucket 
full/removed mode as standby modes for dehumidifiers and the 
determination that ``delay start mode'' would not be considered a 
standby mode. DOE further invites comment as to whether there are any 
modes consistent with the ``active mode,'' ``standby mode,'' or ``off 
mode'' definitions that have not been identified in this NOPR and the 
extent to which these modes would represent significant energy use. 
(See section III.C)
    5. Conventional cooking products standby and off modes. DOE invites 
comment on the proposed establishment of inactive mode and cycle 
finished mode as standby modes for conventional cooking products and 
the determination that ``delay start mode'' and ``Sabbath mode'' would 
not be considered a standby mode. DOE further invites comment as to 
whether there are any modes consistent with the ``active mode,'' 
``standby mode,'' or ``off mode'' definitions that have not been 
identified in this NOPR and the extent to which these modes would 
represent significant energy use. (See section III.C)
    6. Network mode. DOE welcomes comment on whether dishwashers, 
dehumidifiers, and conventional cooking products are currently 
available that incorporate a networking function and whether a 
definition for ``network mode'' and related testing procedures should 
be incorporated into the DOE test procedure. DOE also requests comment 
on appropriate methodologies for measuring energy consumption in a 
network mode for these products, and data on the results and 
repeatability of such testing methodology. (See section III.C)
    7. Default settings. DOE welcomes comment on the suitability of 
using product default settings in testing standby energy consumption, 
on any methodologies that can account for consumer actions that might 
increase energy use, and data on the repeatability of such testing 
procedures. (See section III.D)
    8. Test room ambient temperature. DOE seeks comment on the 
appropriateness of the proposed modified test room ambient temperature 
range for residential dishwashers, dehumidifiers, and conventional 
cooking products, which would allow manufacturers to conduct standby 
mode and off mode testing separately from performance testing under the 
less stringent ambient conditions specified in the IEC Standard 62301 
(First Edition) (i.e., 73.4  9 [deg]F). (See section III.D)
    9. Test period. DOE seeks comment on whether a method in which the 
clock time on conventional cooking products would be set to 3:23 prior 
to a 10-minute stabilization period, followed by a 10-minute 
measurement period commencing at 3:33 would be an acceptable 
alternative to the method that DOE is proposing (i.e., a 10-minute 
initial stabilization period, after which the clock would be set to 
3:23 and another 10-minute stabilization period provided before a 10-
minute measurement starting at a clock time of 3:33). DOE also requests 
comment on its proposed approach requiring results under the 12-hour 
test and the 10-minute test to be within  2 percent of each 
other and welcomes data which would show that some other range is more 
appropriate.
    10. Energy use calculation for standby mode and off mode. DOE 
invites comment on the approach for calculating total energy use for 
standby mode and off mode for dishwashers, dehumidifiers, and 
conventional cooking products. DOE also invites comment on the 
allocation of annual hours and test burden, as well as the alternative 
methodology for allocation of annual hours for each product. (See 
section III.E)
    11. New integrated measures of energy consumption and energy 
efficiency. DOE invites comment on the proposed plan to establish new 
integrated measures of energy consumption for dehumidifiers 
(``integrated annual energy consumption'') and conventional cooking 
products (``integrated energy factor''). DOE also invites comment on 
the proposed plan to modify the existing ``estimated annual energy 
use'' for dishwashers and ``estimated annual operating cost'' metrics 
for dishwashers and conventional cooking products to incorporate the 
revised measurements of standby mode and off mode energy consumption. 
(See section III.F)

VI. Approval of the Office of the Secretary

    The Secretary of Energy has approved publication of this notice of 
proposed rulemaking.

List of Subjects in 10 CFR Part 430

Appendix C to Subpart B of Part 430--Uniform Test Method for Measuring 
the Energy Consumption of Dishwashers

    Note: The procedures and calculations that refer to standby mode 
and off mode energy consumption (i.e., sections 4.5, 4.5.1 through 
4.5.3, and 5.7 of this Appendix C) need not be performed to 
determine compliance with energy conservation standards for 
dishwashers at this time. However, any representation related to 
standby mode and off mode energy consumption of these products made 
after May 31, 2011 must be based upon results generated under this 
test procedure using sections 4.5, 4.5.1 through 4.5.3, and 5.7 and 
disregarding sections 4.4 and 5.6, consistent with the requirements 
of 42 U.S.C. 6293(c)(2). After July 1, 2010, any adopted energy 
conservation standard shall incorporate standby mode and off mode 
energy consumption, and upon the compliance date for such standards, 
compliance with the applicable provisions of this test procedure 
will also be required.

Section 5, Paragraph 5.3.2(a) of IEC 62301.

4. Test Cycle and Measurements

* * * * *
    4.4 Simplified standby mode power. Connect the dishwasher to a 
standby wattmeter or a standby watt-hour meter as specified in 
sections 3.6 and 3.7, respectively, of this Appendix. Select the 
conditions necessary to achieve operation in the simplified standby 
mode as defined in section 1.17 of this Appendix. Monitor the power 
consumption but allow the dishwasher to stabilize for at least 5 
minutes. Then monitor the power consumption for at least an 
additional 5 minutes. If the power level does not change by more 
than 5 percent from the maximum observed value during the later 5 
minutes and if there is no cyclic or pulsing behavior of the load, 
the load can be considered stable. For stable operation, simplified 
standby mode power, Sm, can be recorded directly from the 
standby watt meter in watts or accumulated using the standby watt-
hour meter over a period of at least 5 minutes. For unstable 
operation, the energy must be accumulated using the standby watt-
hour meter over a period of at least 5 minutes and must capture the 
energy use over one or more complete cycles. Calculate the average 
simplified standby mode power, Sm, expressed in watts by 
dividing the accumulated energy consumption by the duration of the 
measurement period.
    4.5 Standby mode and off mode power. Connect the dishwasher to a 
standby mode and off mode watt meter as specified in sections 3.8 of 
this Appendix. Establish the testing conditions set forth in 
sections 2.1, 2.2, and 2.5.2 of this Appendix. For dishwashers that 
drop from a higher power state to a lower power state as discussed 
in Section 5, Paragraph 5.1, note 1 of IEC 62301 (incorporated by 
reference; see Sec.  430.3), allow sufficient time for the 
dishwasher to reach the lower power state before proceeding with the 
test measurement. Follow the test procedure specified in Section 5, 
Paragraph 5.3 of IEC 62301 for testing in each possible mode as 
described in sections 4.5.1 through 4.5.3 of this Appendix, except 
allowing the product to stabilize for at least 30 minutes and using 
an energy use measurement period of not less than 10 minutes. For 
units in which power varies over a cycle, as described in Section 5, 
Paragraph 5.3.2 of IEC 62301, use the average power approach in 
Paragraph 5.3.2(a) of IEC 62301, except allowing the product to 
stabilize for at least 30 minutes and using an energy use 
measurement period of not less than 10 minutes.
    4.5.1 If the dishwasher has an inactive mode, as defined in 
section 1.8, measure and record the average inactive mode power of 
the dishwasher, PIA, in watts.
    4.5.2 If the dishwasher has an off mode, as defined in section 
1.11, measure and record the average off mode power, 
POFF, in watts.
    4.5.3 If the dishwasher has a cycle finished mode, as defined in 
section 1.5, measure and record the average cycle finished mode 
power, PCF, in watts.

5. Calculation of Derived Results From Test Measurements

* * * * *
    5.6 Annual simplified standby energy consumption. Calculate the 
estimated annual simplified standby energy consumption. First 
determine the number of standby hours per year, Hs, 
defined as:

Hs = H - (N x L)

Where,

H = the total number of hours per year = 8766 hours per year,
N = the representative average dishwasher use of 215 cycles per 
year,
L = the average of the duration of the normal cycle and truncated 
normal cycle, for non-soil-sensing dishwashers with a truncated 
normal cycle; the duration of the normal cycle, for non-soil-sensing 
dishwashers without a truncated normal cycle; the average duration 
of the sensor light response, truncated sensor light response, 
sensor medium response, truncated sensor medium response, sensor 
heavy response, and truncated sensor heavy response, for soil-
sensing dishwashers with a truncated cycle option; the average 
duration of the sensor light response, sensor medium response, and 
sensor heavy response, for soil-sensing dishwashers without a 
truncated cycle option.

    Then calculate the estimated annual simplified standby power 
use, S, expressed in kilowatt-hours per year and defined as:

S = Sm x ((Hs)/1000)

Where,

Sm = the simplified standby mode power in watts as 
determined in section 4.4 of this Appendix.

    5.7 Standby mode and off mode annual energy consumption. 
Calculate the standby mode and off mode annual energy

[[Page 75326]]

consumption for dishwashers, ETSO, expressed in kilowatt-
hours per year, according to the following:

ETSO = [(PIA x SIA) + 
(POFF x SOFF) + (PCF x 
SCF)] x K

Where:

PIA= dishwasher inactive mode power, in watts, as 
measured in section 4.5.1.
POFF = dishwasher off mode power, in watts, as measured 
in section 4.5.2.
PCF = dishwasher cycle finished mode power, in watts, as 
measured in section 4.5.3.

    If the dishwasher has both inactive mode and off mode, 
SIA and SOFF both equal STOT/2;
    STOT equals the total number of inactive mode and off 
mode hours per year, defined as:
    If the dishwasher has cycle finished mode, STOT, in 
hours, equals HTSO - SCF;
    If the dishwasher does not have cycle finished mode, 
STOT equals HTSO;

    HTSO equals the total number of standby mode and off 
mode hours per year, defined as:

HTSO = H - (N x L)

Where,

H = the total number of hours per year = 8766 hours per year,
N = the representative average dishwasher use of 215 cycles per 
year,
L = the average of the duration of the normal cycle and truncated 
normal cycle, for non-soil-sensing dishwashers with a truncated 
normal cycle; the duration of the normal cycle, for non-soil-sensing 
dishwashers without a truncated normal cycle; the average duration 
of the sensor light response, truncated sensor light response, 
sensor medium response, truncated sensor medium response, sensor 
heavy response, and truncated sensor heavy response, for soil-
sensing dishwashers with a truncated cycle option; the average 
duration of the sensor light response, sensor medium response, and 
sensor heavy response, for soil-sensing dishwashers without a 
truncated cycle option;

    If the dishwasher has an inactive mode but no off mode, the 
inactive mode annual hours, SIA, is equal to 
STOT and the off mode annual hours, SOFF, is 
equal to 0;
    If the dishwasher has an off mode but no inactive mode, 
SIA is equal to 0 and SOFF is equal to 
STOT;

SCF = 237, dishwasher cycle finished mode annual hours;
K = 0.001 kWh/Wh conversion factor for watt-hours to kilowatt-hours.

Appendix I to Subpart B of Part 430--Uniform Test Method for Measuring 
the Energy Consumption of Conventional Ranges, Conventional Cooking 
Tops, Conventional Ovens, and Microwave Ovens

    Note: The procedures and calculations in this Appendix I need 
not be performed to determine compliance with energy conservation 
standards for conventional ranges, conventional cooking tops, and 
conventional ovens at this time. However, any representation related 
to standby mode and off mode energy consumption of these products 
made after May 31, 2011 must be based upon results generated under 
this test procedure, consistent with the requirements of 42 U.S.C. 
6293(c)(2). After July 1, 2010, any adopted energy conservation 
standard shall incorporate standby mode and off mode energy 
consumption, and upon the compliance date for such standards, 
compliance with the applicable provisions of this test procedure 
will also be required. Although microwave ovens are not currently 
included in this test procedure, future revisions may add relevant 
provisions for measuring active mode, standby mode, and off mode 
energy consumption in those products.

1. Definitions

    1.1 Active mode means a mode in which a conventional cooking 
top, conventional oven, or conventional range is connected to a 
mains power source, has been activated, and is performing the main 
function of producing heat by means of either a gas flame or 
electric resistance heating.
* * * * *
    1.3 Cycle finished mode means a standby mode in which a 
conventional cooking top, conventional oven, or conventional range 
provides continuous status display following operation in active 
mode.
* * * * *
    1.7 IEC 62301 means the test standard published by the 
International Electrotechnical Commission, titled ``Household 
electrical appliances--Measurement of standby power,'' Publication 
62301 (First Edition 2005-06) (incorporated by reference; see Sec.  
430.3).
    1.8 Inactive mode means a standby mode that facilitates the 
activation of active mode by remote switch (including remote 
control), internal sensor, or timer, or that provides continuous 
status display.
* * * * *
    1.10 Off mode means a mode in which the product is connected to 
a mains power source and is not providing any active mode or standby 
mode function, and where the mode may persist for an indefinite 
time. An indicator that only shows the user that the product is in 
the off position is included within the classification of an off 
mode.
* * * * *
    1.12 Secondary energy consumption means any electrical energy 
consumption of a conventional gas oven.
* * * * *
    1.14 Standby mode means any modes where the product is connected 
to a mains power source and offers one or more of the following 
user-oriented or protective functions which may persist for an 
indefinite time: (a) To facilitate the activation of other modes 
(including activation or deactivation of active mode) by remote 
switch (including remote control), internal sensor, or timer; (b) 
continuous functions, including information or status displays 
(including clocks) or sensor-based functions. A timer is a 
continuous clock function (which may or may not be associated with a 
display) that

[[Page 75327]]

provides regular scheduled tasks (e.g., switching) and that operates 
on a continuous basis.

5.3.2(a) of IEC 62301.
* * * * *

3. Test Methods and Measurements

* * * * *
    3.1.1 Conventional oven. Perform a test by establishing the 
testing conditions set forth in section 2, Test Conditions, of this 
Appendix, and adjust any pilot lights of a conventional gas oven in 
accordance with the manufacturer's instructions and turn off the gas 
flow to the conventional cooking top, if so equipped. Before 
beginning the test, the conventional oven shall be at its normal 
nonoperating temperature as defined in section 1.9 and described in 
section 2.6. Set the conventional oven test block W1 
approximately in the center of the usable baking space. If there is 
a selector switch for selecting the mode of operation of the oven, 
set it for normal baking. If an oven permits baking by either forced 
convection by using a fan, or without forced convection, the oven is 
to be tested in each of those two modes. The oven shall remain on 
for at least one complete thermostat ``cut-off/cut-on'' of the 
electrical resistance heaters or gas burners after the test block 
temperature has increased 234 [deg]F (130 [deg]C) above its initial 
temperature.
    3.1.1.1 Self-cleaning operation of a conventional oven. 
Establish the test conditions set forth in Section 2, Test 
Conditions, of this Appendix. Adjust any pilot lights of a 
conventional gas oven in accordance with the manufacturer's 
instructions and turn off the gas flow to the conventional cooking 
top. The temperature of the conventional oven shall be its normal 
nonoperating temperature as defined in section 1.9 and described in 
section 2.6. Then set the conventional oven's self-cleaning process 
in accordance with the manufacturer's instructions. If the self-
cleaning process is adjustable, use the average time recommended by 
the manufacturer for a moderately soiled oven.
* * * * *
    3.1.1.3 Conventional oven standby mode and off mode power. 
Establish the standby mode and off mode testing conditions set forth 
in Section 2, Test Conditions, of this Appendix. For conventional 
ovens that drop from a higher power state to a lower power state as 
discussed in Section 5, Paragraph 5.1, Note 1 of IEC 62301 
(incorporated by reference; see Sec.  430.3), allow sufficient time 
for the conventional oven to reach the lower power state before 
proceeding with the test measurement. Follow the test procedure as 
specified in Section 5, Paragraph 5.3 of IEC 62301 for testing in 
each possible mode as described in 3.1.1.3.1 through 3.1.1.3.3, 
except allowing the product to stabilize for at least 30 minutes and 
using an energy use measurement period not less than 10 minutes. For 
units in which power varies as a function of displayed time in 
standby mode, either: (1) Set the clock time to 3:23 at the end of 
the stabilization period specified in Section 5, Paragraph 5.3 of 
IEC 62301, and use the average power approach described in Section 
5, Paragraph 5.3.2(a) of IEC 62301, but with a single test period of 
10 minutes +0/-2 sec after an additional stabilization period until 
the clock time reaches 3:33; or (2) at any starting clock time, 
allow a stabilization period as described in Section 5, Paragraph 
5.3 of IEC 62301, and use the average power approach described in 
Section 5, Paragraph 5.3.2(a) of IEC 62301, but with a single test 
period of 12 hours +0/-30 sec. Testing may be conducted using either 
a 12-hour test, a 10-minute test, or both tests; however, if a 
manufacturer elects to perform both tests on a unit, the 
manufacturer may only use the results from one of the test (i.e., 
the 12-hour test or the 10-minute test) as the test results for that 
unit. Results of the 10-minute test that are within  2 
percent of the 12-hour test are deemed to be representative of 
average energy use.
    3.1.1.3.1 If the conventional oven has an inactive mode, as 
defined in section 1.8, measure and record the average inactive mode 
power of the conventional oven, PIA, in watts.
    3.1.1.3.2 If the conventional oven has an off mode, as defined 
in section 1.10, measure and record the average off mode power of 
the conventional oven, POFF, in watts.
    3.1.1.3.3 If the conventional oven has a cycle finished mode, as 
defined in section 1.3, measure and record the average cycle 
finished mode power of the conventional oven, PCF, in 
watts.
    3.1.2 Conventional cooking top. Establish the test conditions 
set forth in section 2, Test Conditions, of this Appendix. Adjust 
any pilot lights of a conventional gas cooking top in accordance 
with the manufacturer's instructions and turn off the gas flow to 
the conventional oven(s), if so equipped. The temperature of the 
conventional cooking top shall be its normal

[[Page 75328]]

nonoperating temperature as defined in section 1.9 and described in 
section 2.6. Set the test block in the center of the surface unit 
under test. The small test block, W2, shall be used on 
electric surface units of 7 inches (178 mm) or less in diameter. The 
large test block, W3, shall be used on electric surface 
units over 7 inches (178 mm) in diameter and on all gas surface 
units. Turn on the surface unit under test and set its energy input 
rate to the maximum setting. When the test block reaches 144 [deg]F 
(80 [deg]C) above its initial test block temperature, immediately 
reduce the energy input rate to 255 percent of the 
maximum energy input rate. After 150.1 minutes at the 
reduced energy setting, turn off the surface unit under test.
* * * * *
    3.1.2.2 Conventional cooking top standby mode and off mode 
power. Establish the standby mode and off mode testing conditions 
set forth in section 2, Test Conditions, of this Appendix. For 
conventional cooktops that drop from a higher power state to a lower 
power state as discussed in Section 5, Paragraph 5.1, Note 1 of IEC 
62301 (incorporated by reference; see Sec.  430.3), allow sufficient 
time for the conventional cooktop to reach the lower power state 
before proceeding with the test measurement. Follow the test 
procedure as specified in Section 5, Paragraph 5.3 of IEC 62301 for 
testing in each possible mode as described in sections 3.1.2.2.1 and 
3.1.2.2.2 of this Appendix, except allowing the product to stabilize 
for at least 30 minutes and using an energy use measurement period 
not less than 10 minutes. For units in which power varies as a 
function of displayed time in standby mode, either: (1) set the 
clock time to 3:23 at the end of the stabilization period specified 
in Section 5, Paragraph 5.3 of IEC 62301, and use the average power 
approach described in Section 5, Paragraph 5.3.2(a) of IEC 62301, 
but with a single test period of 10 minutes +0/-2 sec after an 
additional stabilization period until the clock time reaches 3:33; 
or (2) at any starting clock time, allow a stabilization period as 
described in Section 5, Paragraph 5.3 of IEC 62301, and use the 
average power approach described in Section 5, Paragraph 5.3.2(a) of 
IEC 62301, but with a single test period of 12 hours +0/-30 sec. 
Testing may be conducted using either a 12-hour test, a 10-minute 
test, or both tests; however, if a manufacturer elects to perform 
both tests on a unit, the manufacturer may only use the results from 
one of the test (i.e., the 12-hour test or the 10-minute test) as 
the test results for that unit. Results of the 10-minute test that 
are within  2 percent of the 12-hour test are deemed to 
be representative of average energy use.
    3.1.2.2.1 If the conventional cooking top has an inactive mode, 
as defined in section 1.8, measure and record the average inactive 
mode power of the conventional cooking top, PIA, in 
watts.
    3.1.2.2.2 If the conventional cooking top has an off mode, as 
defined in section 1.10, measure and record the average off mode 
power of the conventional cooking top, POFF, in watts.
    3.1.3 Conventional range standby mode and off mode power. 
Establish the standby mode and off mode testing conditions set forth 
in section 2, Test Conditions, of this Appendix. For conventional 
ranges that drop from a higher power state to a lower power state as 
discussed in Section 5, Paragraph 5.1, Note 1 of IEC 62301 
(incorporated by reference; see Sec.  430.3), allow sufficient time 
for the conventional range to reach the lower power state before 
proceeding with the test measurement. Follow the test procedure as 
specified in Section 5, Paragraph 5.3 of IEC 62301 for testing in 
each possible mode as described in sections 3.1.3.1 through 3.1.3.3 
of this Appendix, except allowing the product to stabilize for at 
least 30 minutes and using an energy use measurement period not less 
than 10 minutes. For units in which power varies as a function of 
displayed time in standby mode, either: (1) set the clock time to 
3:23 at the end of the stabilization period specified in Section 5, 
Paragraph 5.3 of IEC 62301, and use the average power approach 
described in Section 5, Paragraph 5.3.2(a) of IEC 62301, but with a 
single test period of 10 minutes +0/-2 sec after an additional 
stabilization period until the clock time reaches 3:33; or (2) at 
any starting clock time, allow a stabilization period as described 
in Section 5, Paragraph 5.3 of IEC 62301, and use the average power 
approach described in Section 5, Paragraph 5.3.2(a) of IEC 62301, 
but with a single test period of 12 hours +0/-30 sec. Testing may be 
conducted using either a 12-hour test, a 10-minute test, or both 
tests; however, if a manufacturer elects to perform both tests on a 
unit, the manufacturer may only use the results from one of the test 
(i.e., the 12-hour test or the 10-minute test) as the test results 
for that unit. Results of the 10-minute test that are within  2 percent of the 12-hour test are deemed to be representative 
of average energy use.
    3.1.3.1 If the conventional range has an inactive mode, as 
defined in section 1.8, measure and record the average inactive mode 
power of the conventional range, PIA, in watts.
    3.1.3.2 If the conventional range has an off mode, as defined in 
section 1.10, measure and record the average off mode power of the 
conventional range, POFF, in watts.
    3.1.3.3 If the conventional range has a cycle finished mode, as 
defined in section 1.3, measure and record the average cycle 
finished mode power of the conventional range, PCF, in 
watts.
* * * * *
    3.2.1 Conventional oven test energy consumption. If the oven 
thermostat controls the oven temperature without cycling on and off, 
measure the energy consumed, EO, when the temperature of 
the block reaches TO (TO is 234 [deg]F (130 
[deg]C) above the initial block temperature, TI). If the 
oven thermostat operates by cycling on and off, make the following 
series of measurements: Measure the block temperature, 
TA, and the energy consumed, EA, or volume of 
gas consumed, VA, at the end of the last ``ON'' period of 
the conventional oven before the block reaches TO. 
Measure the block temperature, TB, and the energy 
consumed, EB, or volume of gas consumed, VB, 
at the beginning of the next ``ON'' period. Measure the block 
temperature, TC, and the energy consumed, EC, 
or volume of gas consumed, VC, at the end of that ``ON'' 
period. Measure the block temperature, TD, and the energy 
consumed, ED, or volume of gas consumed, VD, 
at the beginning of the following ``ON'' period. Energy measurements 
for EO, EA, EB, EC, and 
ED should be expressed in watt-hours (kJ) for 
conventional electric ovens, and volume measurements for 
VA, VB, VC, and VD 
should be expressed in standard cubic feet (L) of gas for 
conventional gas ovens. For a gas oven, measure in watt-hours (kJ) 
any electrical energy, EIO, consumed by an ignition 
device or other electrical components required for the operation of 
a conventional gas oven while heating the test block to 
TO.
    3.2.1.1 Conventional oven average test energy consumption. If 
the conventional oven permits baking by either forced convection or 
without forced convection and the oven thermostat does not cycle on 
and off, measure the energy consumed with the forced convection 
mode, (EO)1, and without the forced convection 
mode, (EO)2, when the temperature of the block 
reaches TO (TO is 234 [deg]F (130 [deg]C) 
above the initial block temperature, TI). If the 
conventional oven permits baking by either forced convection or 
without forced convection and the oven thermostat operates by 
cycling on and off, make the following series of measurements with 
and without the forced convection mode: Measure the block 
temperature, TA, and the energy consumed, EA, 
or volume of gas consumed, VA, at the end of the last 
``ON'' period of the conventional oven before the block reaches 
TO. Measure the block temperature, TB, and the 
energy consumed, EB, or volume of gas consumed, 
VB, at the beginning of the next ``ON'' period. Measure 
the block temperature, TC, and the energy consumed, 
EC, or volume of gas consumed, VC, at the end 
of that ``ON'' period. Measure the block temperature, TD, 
and the energy consumed, ED, or volume of gas consumed, 
VD, at the beginning of the following ``ON'' period. 
Energy measurements for EO, EA, EB, 
EC, and ED should be expressed in watt-hours 
(kJ) for conventional electric ovens, and volume measurements for 
VA, VB, VC, and VD 
should be expressed in standard cubic feet (L) of gas for 
conventional gas ovens. For a gas oven that can be operated with or 
without forced convection, measure in watt-hours (kJ) any electrical 
energy consumed by an ignition device or other electrical components 
required for the operation of a conventional gas oven while heating 
the test block to TO using the forced convection mode, 
(EIO)1, and without using the forced 
convection mode, (EIO)2.
    3.2.1.2 Energy consumption of self-cleaning operation. Measure 
the energy consumption, ES, in watt-hours (kJ) of 
electricity or the volume of gas consumption, VS, in 
standard cubic feet (L) during the self-cleaning test set forth in 
section 3.1.1.1 of this Appendix. For a gas oven, also measure in 
watt-hours (kJ) any electrical energy, EIS, consumed by 
ignition devices or other electrical components required during the 
self-cleaning test.
* * * * *
    3.2.1.4 Standby mode and off mode energy consumption. Make 
measurements as specified in section 3.1.1.3 of this Appendix.

[[Page 75329]]

If the conventional oven is capable of operating in inactive mode, 
measure the average inactive mode power of the conventional oven,

     The procedures and calculations that refer to standby mode and 
off mode energy consumption (i.e., sections 3.2, 3.2.1 through 
3.2.4, 4.2, 4.2.1 through 4.2.4, 5.1, and 5.2 of this Appendix X) 
need not be performed to determine compliance with energy 
conservation standards for dehumidifiers at this time. However, any 
representation related to standby mode and off mode energy 
consumption of these products made after May 31, 2011 must be based 
upon results generated under this test procedure, consistent with 
the requirements of 42 U.S.C. 6293(c)(2). After July 1, 2010, any 
adopted energy conservation standard shall incorporate standby mode 
and off mode energy consumption, and upon the compliance date for 
such standards, compliance with the applicable provisions of this 
test procedure will also be required.

1. Scope

    This appendix covers the test requirements used to measure the 
energy performance of dehumidifiers.

2. Definitions

    a. Active mode means a mode in which a dehumidifier is connected 
to a mains power source, has been activated, and is performing the 
main functions of removing moisture from air by drawing moist air 
over a refrigerated coil using a fan, or circulating air through 
activation of the fan without activation of the refrigeration 
system.
    b. Bucket full/removed mode means a standby mode in which the 
dehumidifier has automatically powered off its main function by 
detecting when the water bucket is full or has been removed.
    c. Energy factor for dehumidifiers means a measure of energy 
efficiency of a dehumidifier calculated by dividing the water 
removed from the air by the energy consumed, measured in liters per 
kilowatt-hour (L/kWh).
    d. IEC 62301 means the test standard published by the 
International Electrotechnical Commission, titled ``Household 
electrical appliances--Measurement of standby power,'' Publication 
62301 (First Edition 2005-06) (incorporated by reference; see Sec.  
430.3).
    e. Inactive mode means a standby mode that facilitates the 
activation of active mode by remote switch (including remote 
control), internal sensor, or timer, or that provides continuous 
status display.
    f. Off mode means a mode in which the dehumidifier is connected 
to a mains power source and is not providing any active mode or 
standby mode function, and where the mode may persist for an 
indefinite time. An indicator that only shows the user that the 
dehumidifier is in the off position is included within the 
classification of an off mode.
    g. Off-cycle mode means a standby mode in which the 
dehumidifier:
    (1) Has cycled off its main function by humidistat or humidity 
sensor;
    (2) Does not have its fan or blower operating; and
    (3) Will reactivate the main function according to the 
humidistat or humidity sensor signal.
    h. Product capacity for dehumidifiers means a measure of the 
ability of the dehumidifier to remove moisture from its surrounding 
atmosphere, measured in pints collected per 24 hours of continuous 
operation.
    i. Standby mode means any modes where the dehumidifier is 
connected to a mains power source and offers one or more of the 
following user-oriented or protective functions which may persist 
for an indefinite time:
    (1) To facilitate the activation of other modes (including 
activation or deactivation of active mode) by remote switch 
(including remote control), internal sensor, or timer;
    (2) Continuous functions, including information or status 
displays (including clocks) or sensor-based functions. A timer is a 
continuous clock function (which may or may not be associated with a 
display) that provides regular scheduled tasks (e.g., switching) and 
that operates on a continuous basis.

3. Test Apparatus and General Instructions

    3.1 Active mode. The test apparatus and instructions for testing 
dehumidifiers shall conform to the requirements specified in section 
1, ``Definitions,'' section 2,

[[Page 75334]]

``Qualifying Products,'' and section 4, ``Test Criteria,'' of the 
EPA's ``ENERGY STAR Program Requirements for Dehumidifiers,'' 
effective January 1, 2001 (incorporated by reference, see Sec.  
430.3). Record measurements at the resolution of the test 
instrumentation. Round off calculations to the same number of 
significant digits as the previous step. Round the final minimum 
energy factor value to two decimal places as follows:
    (i) A fractional number at or above the midpoint between two 
consecutive decimal places shall be rounded up to the higher of the 
two decimal places; or
    (ii) A fractional number below the midpoint between two 
consecutive decimal places shall be rounded down to the lower of the 
two decimal places.
    3.2 Standby mode and off mode.
    3.2.1 Installation requirements. For the standby mode and off 
mode testing, the dehumidifier shall be installed in accordance with 
Section 5, Paragraph 5.2 of IEC 62301 (incorporated by reference, 
see Sec.  430.3).
    3.2.2 Electrical energy supply.
    3.2.2.1 Electrical supply. For the standby mode and off mode 
testing, maintain the electrical supply voltage indicated in section 
4, ``Test Criteria,'' of the EPA's ``ENERGY STAR Program 
Requirements for Dehumidifiers,'' effective January 1, 2001, 
(incorporated by reference, see Sec.  430.3) and the electrical 
supply frequency indicated in section 4, ``Test Criteria,'' of the 
EPA's ``ENERGY STAR Program Requirements for Dehumidifiers,'' 1 percent.
    3.2.2.2 Supply voltage waveform. For the standby mode and off 
mode testing, maintain the electrical supply voltage waveform 
indicated in Section 4, Paragraph 4.4 of IEC 62301, (incorporated by 
reference; see Sec.  430.3).
    3.2.3 Standby watt meter. The watt meter used to measure standby 
mode and off mode power consumption shall have the resolution 
specified in Section 4, Paragraph 4.5 of IEC 62301 (incorporated by 
reference, see Sec.  430.3). The watt meter shall also be able to 
record a ``true'' average power as specified in Section 5, Paragraph 
5.3.2(a) of IEC 62301.
    3.2.4 Standby and off mode ambient temperature. For standby mode 
and off mode testing, maintain room ambient air temperature 
conditions as specified in Section 4, Paragraph 4.2 of IEC 62301 
(incorporated by reference; see Sec.  430.3).

4. Test Measurement

    4.1 Active mode. Measure the energy factor for dehumidifiers, 
expressed in liters per kilowatt hour (L/kWh) and product capacity 
in pints per day (pints/day), in accordance with the test 
requirements specified in section 4, ``Test Criteria,'' of EPA's 
``ENERGY STAR Program Requirements for Dehumidifiers,'' effective 
January 1, 2001 (incorporated by reference, see Sec.  430.3).
    4.2 Standby mode and off mode. Establish the testing conditions 
set forth in section 3.2 of this Appendix. For dehumidifiers that 
drop from a higher power state to a lower power state as discussed 
in Section 5, Paragraph 5.1, Note 1 of IEC 62301, (incorporated by 
reference; see Sec.  430.3), allow sufficient time for the 
dehumidifier to reach the lower power state before proceeding with 
the test measurement. Follow the test procedure specified in Section 
5, Paragraph 5.3 of IEC 62301 for testing in each possible mode as 
described in sections 4.2.1 through 4.2.4 of this Appendix, except 
allowing the product to stabilize for at least 30 minutes and using 
an energy use measurement period of not less than 10 minutes. For 
units in which power varies over a cycle, as described in Section 5, 
Paragraph 5.3.2 of IEC 62301, use the average power approach in 
Section 5, Paragraph 5.3.2(a) of IEC 62301, except allowing the 
product to stabilize for at least 30 minutes and using an energy use 
measurement period of not less than 10 minutes.

5. Calculation of Derived Results From Test Measurements

    5.1 Standby mode and off mode annual energy consumption. 
Calculate the standby mode and off mode annual energy consumption 
for dehumidifiers, ETSO, expressed in kilowatt-hours per 
year, according to the following:

ETSO = [(PIA x SIA) + 
(POC x SOC) + (PBFR x 
SBFR) + (POFF x SOFF)] x K

Where:

PIA = dehumidifier inactive mode power, in watts, as 
measured in section 4.2.1 of this Appendix.
POC = dehumidifier off-cycle mode power, in watts, as 
measured in section 4.2.2 of this Appendix.

watts, as measured in section 4.2.3 of this Appendix.
POFF = dehumidifier off mode power, in watts, as measured 
in section 4.2.4 of this Appendix.

    If the dehumidifier has an inactive mode and off-cycle mode but 
no off mode, the inactive mode annual hours, SIA, is 
equal to STOT/2; the off-cycle mode annual hours, 
SOC, is equal to STOT/2; and the off mode 
annual hours, SOFF, is equal to 0;
    STOT equals the total number of inactive mode, off-
cycle mode, and off mode hours per year, defined as:
    If the dehumidifier has bucket full/removed mode, 
STOT equals 3,024 hours;
    If the dehumidifier does not have bucket full/removed mode, 
STOT equals 3,681 hours;
    If the dehumidifier has an inactive mode and off mode but no 
off-cycle mode, the inactive mode annual hours, SIA, is 
equal to STOT/2; the off mode annual hours, 
SOFF, is equal to STOT/2; and the off-cycle 
mode annual hours, SOC, is equal to 0;
    If the dehumidifier has an inactive mode but no off-cycle mode 
or off mode, the inactive mode annual hours, SIA, is 
equal to STOT, and the off-cycle mode annual hours, 
SOC, and the off mode annual hours, SOFF, are 
each equal to 0;
    If the dehumidifier has an off-cycle mode and off mode but no 
inactive mode, the off-cycle mode annual hours, SOC, is 
equal to STOT/2; the off mode annual hours, 
SOFF, is equal to STOT/2; and the inactive 
mode annual hours, SIA, is equal to 0;
    If the dehumidifier has an off-cycle mode but no off mode or 
inactive mode, the off-cycle mode annual hours, SOC, is 
equal to STOT, and the off mode annual hours, 
SOFF, and the inactive mode annual hours, SIA, 
are each equal to 0;
    If the dehumidifier has an off mode but no inactive mode or off-
cycle mode, the off mode annual hours, SOFF, is equal to 
STOT, and the inactive mode annual hours, SIA, 
and the off-cycle mode annual hours, SOC, are both equal 
to 0;
    If the dehumidifier has an inactive mode, off-cycle mode, and 
off mode, the inactive mode annual hours, SIA, is equal 
to STOT/3; the off-cycle mode annual hours, 
SOC, is equal to STOT/3; and the off mode 
annual hours, SOFF, is equal to STOT/3;

SBFR = 657, dehumidifier bucket full/removed mode annual 
hours;
K = 0.001 kWh/Wh conversion factor for watt-hours to kilowatt-hours.

    5.2 Integrated energy factor. Calculate the integrated energy 
factor, IEF, expressed in liters per kilowatt-hour, rounded to two 
decimal places, according to the following:

IEF = LW/(Eactive + ((ETSO x 24)/
Sactive))

Where:

LW = water removed from the air during dehumidifier 
energy factor test, in liters, as measured in section 4.1 of this 
Appendix.
Eactive = dehumidifier energy factor test energy 
consumption, in kilowatt-hours, as measured in section 4.1 of this 
Appendix.
ETSO = standby mode and off mode annual energy 
consumption, in kilowatt-hours per year, as calculated in section 
5.1 of this Appendix.
24 = hours per day.
Sactive = 1,095, dehumidifier active mode annual hours.
