Case Number 2021-001

Interim Waiver Order

I. Background and Authority

    The Energy Policy and Conservation Act, as amended (``EPCA''),\2\ 
among other things, authorizes the U.S. Department of Energy (``DOE'') 
to regulate the energy efficiency of a number of consumer products and 
industrial equipment. Title III, Part B \3\ of EPCA established the 
Energy Conservation Program for Consumer Products Other Than 
Automobiles, which sets forth a variety of provisions designed to 
improve energy efficiency for certain types of consumer products. These 
products include central air conditioners and central air conditioning 
heat pumps (``CACs'' and ``HPs''), the subject of this Interim Waiver 
Order. (42 U.S.C. 6292(a)(3))
---------------------------------------------------------------------------

    \2\ All references to EPCA in this document refer to the statute 
as amended through the Energy Act of 2020, Public Law 116-260 (Dec. 
27, 2020).
    \3\ For editorial reasons, upon codification in the U.S. Code, 
Part B was redesignated as Part A.
---------------------------------------------------------------------------

    The energy conservation program under EPCA consists essentially of 
four parts: (1) Testing, (2) labeling, (3) Federal energy conservation 
standards, and (4) certification and enforcement procedures. Relevant 
provisions of EPCA include definitions (42 U.S.C. 6291), test 
procedures (42 U.S.C. 6293), labeling provisions (42 U.S.C. 6294), 
energy conservation standards (42 U.S.C. 6295), and the authority to 
require information and reports from manufacturers (42 U.S.C. 6296).
    The Federal testing requirements consist of test procedures that 
manufacturers of covered products must use as the basis for: (1) 
Certifying to DOE that their products comply with the applicable energy 
conservation

[[Page 40536]]

standards adopted pursuant to EPCA (42 U.S.C. 6295(s)), and (2) making 
representations about the efficiency of that product (42 U.S.C. 
6293(c)). Similarly, DOE must use these test procedures to determine 
whether the covered product complies with relevant standards 
promulgated under EPCA. (42 U.S.C. 6295(s))
    Under 42 U.S.C. 6293, EPCA sets forth the criteria and procedures 
DOE is required to follow when prescribing or amending test procedures 
for covered products. EPCA requires that any test procedures prescribed 
or amended under this section must be reasonably designed to produce 
test results which reflect the energy efficiency, energy use or 
estimated annual operating cost of a covered product during a 
representative average use cycle or period of use and requires that 
test procedures not be unduly burdensome to conduct. (42 U.S.C. 
6293(b)(3)) The current test procedure for CACs and HPs is contained in 
the Code of Federal Regulations (``CFR'') at 10 CFR part 430, subpart 
B, appendix M, Uniform Test Method for Measuring the Energy Consumption 
of Central Air Conditioners and Heat Pumps (``Appendix M''). Beginning 
January 1, 2023, any representations made with respect to the energy 
use, power, or efficiency of CACs and HPs must be based on the results 
of testing pursuant to 10 CFR part 430, subpart B, appendix M1, Uniform 
Test Method for Measuring the Energy Consumption of Central Air 
Conditioners and Heat Pumps (``Appendix M1'').
    Under 10 CFR 430.27,\4\ any interested person may submit a petition 
for waiver from DOE's test procedure requirements. DOE will grant a 
waiver from the test procedure requirements if DOE determines either 
that the basic model for which the waiver was requested contains a 
design characteristic that prevents testing of the basic model 
according to the prescribed test procedures, or that the prescribed 
test procedures evaluate the basic model in a manner so 
unrepresentative of its true energy consumption characteristics as to 
provide materially inaccurate comparative data. 10 CFR 430.27(f)(2). A 
petitioner must include in its petition any alternate test procedures 
known to the petitioner to evaluate the performance of the product type 
in a manner representative of the energy consumption characteristics of 
the basic model. 10 CFR 430.27(b)(1)(iii). DOE may grant the waiver 
subject to conditions, including adherence to alternate test 
procedures. 10 CFR 430.27(f)(2).
---------------------------------------------------------------------------

    \4\ On December 11, 2020, DOE published an amendment to the 
waiver petition regulation at 10 CFR 430.27, which became effective 
beginning January 11, 2021. The Goodman petition was received prior 
to the effective date of the amendment and therefore is being 
processed pursuant to the regulation in effect at the time of 
receipt. References to 10 CFR 430.27 in this notification refer to 
the 10 CFR 430.27 in the 10 CFR parts 200 to 499 edition revised as 
of January 1, 2021.
---------------------------------------------------------------------------

    As soon as practicable after the granting of any waiver, DOE will 
publish in the Federal Register a notice of proposed rulemaking to 
amend its regulations so as to eliminate any need for the continuation 
of such waiver. 10 CFR 430.27(l). As soon thereafter as practicable, 
DOE will publish in the Federal Register a final rule. Id.
    The waiver process also provides that DOE may grant an interim 
waiver if it appears likely that the underlying petition for waiver 
will be granted and/or if DOE determines that it would be desirable for 
public policy reasons to grant immediate relief pending a determination 
on the underlying petition for waiver. 10 CFR 430.27(e)(2). Within one 
year of issuance of an interim waiver, DOE will either: (i) Publish in 
the Federal Register a determination on the petition for waiver; or 
(ii) publish in the Federal Register a new or amended test procedure 
that addresses the issues presented in the waiver. 10 CFR 430.27(h)(1). 
When DOE amends the test procedure to address the issues presented in a 
waiver, the waiver will automatically terminate on the date on which 
use of that test procedure is required to demonstrate compliance. 10 
CFR 430.27(h)(2).

II. Goodman's Petition for Waiver and Interim Waiver

    On January 8, 2021, Goodman filed a petition for waiver and interim 
waiver from the test procedure for CACs and HPs set forth in Appendix M 
and Appendix M1.\5\ Goodman stated that Appendix M and Appendix M1 \6\ 
do not include provisions for determining cooling intermediate air 
volume rate, cooling minimum air volume rate, and heating intermediate 
air volume rate for the variable-speed coil-only single-split systems 
specified in its petition. Goodman asserts that although the CAC and HP 
test procedures at Appendix M and Appendix M1 generally provide for 
testing of variable-speed systems, they do not provide for testing of 
variable-speed coil-only single-split systems. Coil-only indoor units 
are distributed in commerce without an indoor blower or separate 
designated air mover. Such systems would be installed either with an 
existing air mover (e.g., a furnace) or with a new air mover which is 
not designed by the manufacturer. The DOE test procedure provides 
instructions for setting airflow during testing to represent such 
indoor blowers or air movers. For example, the DOE test procedure 
provides instructions for setting minimum cooling air volume rate for 
ducted two-capacity coil-only systems in section 3.1.4.2(c) of Appendix 
M and Appendix M1. However, such instructions are not provided for 
testing variable-speed outdoor units paired with coil-only indoor 
units. Goodman seeks to use an alternate test procedure that provides 
instructions for setting air volume rates for all required tests to 
rate and test the basic models \7\ listed in its petition.
---------------------------------------------------------------------------

    \5\ The specific basic models for which the petition applies are 
28 Daikin basic models: DX17VSS181AA, DX17VSS181BA, DX17VSS241AA, 
DX17VSS241BA, DX17VSS301AA, DX17VSS301BA, DX17VSS361AA, 
DX17VSS361BA, DX17VSS421AA, DX17VSS421BA, DX17VSS481AA, 
DX17VSS481BA, DX17VSS601AA, DX17VSS601BA, DZ17VSA181AA, 
DZ17VSA181BA, DZ17VSA241AA, DZ17VSA241BA, DZ17VSA301AA, DZ17VSA301BA 
DZ17VSA361AA, DZ17VSA361BA, DZ17VSA421AA, DZ17VSA421BA, 
DZ17VSA481AA, DZ17VSA481BA, DZ17VSA601AA, and DZ17VSA601BA. These 
basic model names were provided by Goodman in its revised petition 
on March 30, 2021.
    \6\ As noted, Appendix M1 is not required until January 1, 2023. 
However, manufacturers may determine it necessary to conduct testing 
under Appendix M1 in advance of that date to ensure compliance 
beginning on that future date.
    \7\ In Goodman's initial petition (EERE-2021-BT-WAV-0001-0001), 
three basic model numbers were identified. In an email received 
January 19, 2021 (EERE-2021-BT-WAV-0001-0002), Goodman clarified 
that one basic model number was listed in error, and that only two 
basic models are the subject of their petition. In an email received 
January 27, 2021 (EERE-2021-BT-WAV-0001-0003), Goodman clarified 
that they had made an error in listing the basic model numbers 
subject to their petition, and that there are 14 basic model numbers 
to which their petition applies. In an email received on March 30, 
2021 (EERE-2021-BT-WAV-0001-0004), Goodman clarified another error 
in their 14 basic model numbers, which included wildcard characters. 
Goodman corrected their petition to list 28 basic model numbers 
without any wildcards.
---------------------------------------------------------------------------

    Goodman also requests an interim waiver from the existing DOE test 
procedure. DOE will grant an interim waiver if it appears likely that 
the petition for waiver will be granted, and/or if DOE determines that 
it would be desirable for public policy reasons to grant immediate 
relief pending a determination of the petition for waiver. 10 CFR 
430.27(e)(2).
    Based on the assertions in the petition, absent an interim waiver, 
the specified variable-speed coil-only single-split models that are 
subject of the waiver cannot be tested under the existing test 
procedure because

[[Page 40537]]

Appendix M (and Appendix M1) does not include provisions for 
determining certain air volume rates for variable-speed coil-only 
single-split systems.

III. Requested Alternate Test Procedure

    EPCA requires that manufacturers use DOE test procedures when 
making representations about the energy consumption and energy 
consumption costs of covered products. (42 U.S.C. 6293(c)). Consistency 
is important when making representations about the energy efficiency of 
products, including when demonstrating compliance with applicable DOE 
energy conservation standards. Pursuant to 10 CFR 430.27, and after 
consideration of public comments on the petition, DOE may establish in 
a subsequent Decision and Order an alternate test procedure for the 
basic models addressed by the Interim Waiver Order.
    In its petition, Goodman notes that DOE has granted waivers to GD 
Midea Heating & Ventilating Equipment Co., Ltd. (``GD Midea'') and TCL 
air conditioner (zhongshan) Co. Ltd. (``TCL AC'') for variable-speed 
coil-only single-split systems. 83 FR 56065 (Nov. 9, 2018) and 84 FR 
11941 (Mar. 29, 2019), respectively. The Midea and TCL waivers require 
use of an alternate test procedure that specifies the same air volume 
rate for all tests, consistent with the controls of the systems 
addressed in those waivers, which do not have the provision for control 
signals to vary indoor fan speed. In contrast, Goodman states that its 
systems do have provisions for installing control components that can 
select lower indoor fan speed when the outdoor unit compressor is not 
running at full speed. As described by Goodman, the control takes 
advantage of the fact that nearly all central air-conditioning and 
heating system indoor fans have multiple speeds. The alternate test 
procedure requested by Goodman would specify lower airflow rates for 
certain tests. This parallels the test procedure approach for ducted 
two-stage coil-only systems.\8\
---------------------------------------------------------------------------

    \8\ Section 3.1.4.2.c of Appendix M, and section 3.1.4.2.c of 
Appendix M1, which becomes the appropriate test procedure on or 
after January 1, 2023.
---------------------------------------------------------------------------

    In its petition, Goodman requests that it be allowed to use a 
similar alternate test procedure as that granted to GD Midea and TCL 
AC, but Goodman's alternate test procedure would be different in that 
it would utilize the procedures for ducted two-stage coil-only systems 
and use the cooling minimum air volume rate as determined in section 
3.1.4.2.c of Appendix M and Appendix M1 for the cooling minimum, 
heating minimum, cooling intermediate, and heating intermediate test 
conditions. In the alternate test procedure requested by Goodman, the 
cooling minimum air volume rate is the higher of either the rate 
specified by the instructions included with the unit or 75% of the 
cooling full-load air volume rate. All other requirements of Appendix M 
(and Appendix M1) remain identical.

IV. Interim Waiver Order

    DOE has reviewed Goodman's application for an interim waiver, the 
alternate test procedure requested by Goodman, publicly available 
specification sheets and installation manuals, and the additional 
materials Goodman provided in support of its petition. Goodman's 
alternate test procedure proposes for its variable-speed coil-only 
systems to be tested using a minimum air volume rate that is determined 
using the same procedures as for ducted two-capacity coil-only units. 
DOE does not expect that there would be any differences in the typical 
installation scenarios for two-capacity or variable-speed coil-only 
systems, i.e., the typical control wiring for a furnace fan paired with 
a coil-only indoor unit would enable two stages of fan control, 
regardless of the number of compressor stages. Therefore, DOE agrees 
with aligning the minimum air volume rate between two-capacity and 
variable-speed coil-only indoor units and believes that the proposed 
alternate test procedure is appropriate for use with the models listed 
in Goodman's petition. Based on DOE's review, the alternate test 
procedure appears to allow for the accurate measurement of the energy 
efficiency of the products specified in Goodman's petition, while 
alleviating the testing problems associated with Goodman's testing for 
these basic models. Consequently, it appears likely that Goodman's 
petition for waiver will be granted. Furthermore, DOE has determined 
that it is desirable for public policy reasons to grant Goodman 
immediate relief pending a determination of the petition for waiver.
    For the reasons stated, it is ordered that:
    (1) Goodman must test and rate the following Daikin brand single-
split central air conditioner and heat pump (``CAC and HP'') basic 
models, which are comprised of the individual combinations listed 
below,\9\ using the alternate test procedure set forth in paragraph 
(2).
---------------------------------------------------------------------------

    \9\ The specified basic models contain individual combinations, 
which do not specify a particular air mover, and that each consist 
of an outdoor unit that uses a variable speed compressor matched 
with a coil-only indoor unit.

    (2) The alternate test procedure for the Goodman basic models 
identified in paragraph (1) of this Interim Waiver Order is the test 
procedure for CACs and HPs prescribed by DOE at 10 CFR part 430, 
subpart B, appendix M (``Appendix

[[Page 40539]]

M'') and, for representations made on and after January 1, 2023, at 10 
CFR part 430, subpart B, appendix M1 (``Appendix M1''), except that for 
coil-only combinations:
    In 3.1.4.2., Cooling Minimum Air Volume Rate, include:
    f. For ducted variable-speed compressor systems tested with a coil-
only indoor unit, the cooling minimum air volume rate is the higher of 
(1) the rate specified by the installation instructions included with 
the unit by the manufacturer or (2) 75 percent of the cooling full-load 
air volume rate. During the laboratory tests on a coil-only (fanless) 
system, obtain this cooling minimum air volume rate regardless of the 
pressure drop across the indoor coil assembly.
    In 3.1.4.3., Cooling Intermediate Air Volume Rate, include:
    d. For ducted variable-speed compressor systems tested with a coil-
only indoor unit, the cooling intermediate air volume rate is the same 
as the cooling minimum air volume rate determined in section 3.1.4.2.f, 
without regard to the pressure drop across the indoor coil assembly.
    In 3.1.4.6., Heating Intermediate Air Volume Rate (limited to 
ducted coil-only variable-speed heat pumps), include:
    d. For ducted variable-speed compressor systems tested with a coil-
only indoor unit, use the heating minimum air volume rate as determined 
in section 3.1.4.5.1.a.(3), without regard to the pressure drop across 
the indoor coil assembly.
    The cooling minimum, cooling intermediate, heating minimum, and 
heating intermediate air volume rates are all identical under these 
provisions. All other requirements of Appendix M and Appendix M1 remain 
applicable.
    (3) Representations. Goodman may not make representations about 
efficiency of the basic models listed in paragraph (1) for compliance, 
marketing, or other purposes unless that basic model has been tested in 
accordance with the provisions set forth in this alternate test 
procedure and such representations fairly disclose the results of such 
testing.
    (4) This Interim Waiver Order shall remain in effect according to 
the provisions of 10 CFR 430.27.
    (5) This Interim Waiver Order is issued on the condition that the 
statements, representations, and documentary materials provided by 
Goodman are valid. If Goodman makes any modifications to the controls 
or configurations of a basic model subject to this Interim Waiver 
Order, such modifications will render the waiver invalid with respect 
to that basic model, and Goodman will either be required to use the 
current Federal test method or submit a new application for a test 
procedure waiver. DOE may rescind or modify this Interim Waiver Order 
at any time if it determines the factual basis underlying the petition 
for Interim Waiver Order is incorrect, or the results from the 
alternate test procedure are unrepresentative of a basic models' true 
energy consumption characteristics. 10 CFR 430.27(k)(1). Likewise, 
Goodman may request that DOE rescind or modify the Interim Waiver Order 
if Goodman discovers an error in the information provided to DOE as 
part of its petition, determines that the Interim Waiver Order is no 
longer needed, or for other appropriate reasons. 10 CFR 430.27(k)(2).
    (6) Issuance of this Interim Waiver Order does not release Goodman 
from the applicable requirements set forth at 10 CFR part 429.
    DOE makes decisions on waivers and interim waivers for only those 
basic models specifically set out in the petition, not future models 
that may be manufactured by the petitioner. Goodman may submit a new or 
amended petition for waiver and request for grant of interim waiver, as 
appropriate, for additional basic models of CACs and HPs. 
Alternatively, if appropriate, Goodman may request that DOE extend the 
scope of a waiver or an interim waiver to include additional basic 
models employing the same technology as the basic model(s) set forth in 
the original petition consistent with 10 CFR 430.27(g).

Re: Petition for Waiver and Interim Waiver on Test Procedure for 
Certain Variable-Speed Central Air Conditioners

    Dear Sir/Ms.: Goodman Manufacturing Company, L.P. (``Goodman'') 
respectfully submits petitions for waiver and interim waiver to the 
Department of Energy (``DOE'') from certain provisions in the current 
federal test procedure for central air conditioners and heat pumps in 
Appendix M to Subpart B of 10 CFR part 430 (``Appendix M'') applicable 
until January 1, 2023, and the future test procedure set forth in 
Appendix M1 to Subpart B of 10 CFR part 430 (``Appendix M1'') and 
applicable on or after January 1, 2023, specifically for ducted coil-
only variable-speed single-split system central air conditioners 
(``VSAC'') and variable-speed single-split system heat pumps 
(``VSHP'').
    Goodman is a member of Daikin Group, one of the largest heating, 
ventilation and air conditioning (``HVAC'') manufacturers in the world. 
Goodman is headquartered in Houston, Texas, and employs thousands of 
workers across the United States. The company manufactures residential 
and light commercial heating and cooling equipment, and its products 
are sold and installed by contractors in every American state.

I. Introduction

    While the federal test procedures in Appendix M and Appendix M1 
specify tests for variable- speed systems, provisions specific to 
testing ducted coil-only VSACs and VSHPs do not exist in the test 
procedure. As explained further below, Goodman is seeking a waiver and 
an interim waiver from the federal test procedure to allow for testing 
and representations of performance metrics for certain ducted coil-only 
VSACs and VSHPs. Goodman's petition is consistent with previous DOE 
Decisions and Orders that granted waivers to other manufacturers

[[Page 40540]]

from specified portions of the DOE test procedure for determining the 
energy efficiency of central air conditioners and heat pumps.\1\
---------------------------------------------------------------------------

    \1\ See e.g., TCL AC (Case No. 2018-009, Docket EERE-2018-BT-
WAV-0013, granted 3/29/19, published 84FR11941) and GD Midea (Case 
No. 2017-013, Docket EERE-2017-BT-WAV-0060, granted 11/09/18, 
published 83FR56065).
---------------------------------------------------------------------------

    Goodman is asking the DOE to approve a proposed alternate test 
procedure that differs only slightly from the alternate test procedure 
DOE previously approved for other manufacturers. The difference is 
rather than using the full-load air volume rate for all tests, Goodman 
proposes to use the minimum air volume rate for intermediate and 
minimum speed tests, which aligns with the process in Appendix M and 
Appendix M1 for ducted two-stage coil-only systems.\2\ Our request 
would utilize the cooling minimum air volume rate for cooling 
intermediate and cooling minimum tests. Further, in lieu of using the 
heating full-load air volume rate for the heating intermediate air 
volume rate, Goodman proposes to use the heating minimum air volume 
rate for ducted two-stage coil-only systems determined in section 
3.1.4.5.1.a.(3). of the current federal test procedure. Additional 
details about Goodman's proposed alternate test procedure are provided 
in Section V of this petition.
---------------------------------------------------------------------------

    \2\ Section 3.1.4.2.c. of Appendix M prior to January 1, 2023, 
and Section 3.1.4.2.c. of Appendix M1 on or after January 1, 2023.
---------------------------------------------------------------------------

    Some information provided is confidential business information 
(``CBI''), therefore in accordance with 10 CFR 1004.11, we are 
submitting one copy of this petition with CBI information redacted. CBI 
information is indicated by being enclosed in square brackets, 
``[``and'']''.

II. Particular Basic Models for Which Goodman Requests a Waiver and 
Interim Waiver

    As required by 10 CFR 430.27(b)(i), Goodman is providing, in 
Appendix I of this petition, a list of the basic models for which 
Goodman requests a waiver from the test procedure. Each indoor unit is 
equipped with an electronic expansion valve. As a result, both the 
outdoor unit and indoor coil will communicate with each other to 
control superheat and subcooling. Our system control has an output that 
allows for a standard single-pole double-throw relay (``SPDT'') to be 
field installed to control indoor fan speed.\3\ For conditions other 
than full-load, lowering the air volume rate from full-load to a lesser 
quantity provides benefits to the consumer by helping to maintain 
humidity control, providing more comfortable discharge air temperatures 
and reducing indoor fan energy consumption. Therefore, allowing 
differing airflows during the test will result in a better 
representation of the unit's actual performance for consumers and 
further DOE's goal under EPCA of more accurate testing.
---------------------------------------------------------------------------

    \3\ The installer would supply a SPDT relay to control the fan 
speed of the existing furnace. This is the same scheme used to 
change fan speed for two-stage systems today that is covered in 
today's DOE test procedure for those products. For two-stage 
systems, the installer will use a 24-volt signal from the room 
thermostat (either Y1 or Y2) to apply to the coil of the SPDT relay, 
which switches the fan speed as needed. For Goodman's variable speed 
applications, the installer will use the 24-volt signal from the 
electronic expansion valves in both the outdoor and indoor units.
---------------------------------------------------------------------------

III. List of Manufacturers

    As required by 10 CFR 430.27(b)(ii), Goodman is providing, in 
Appendix II of this petition, a list of manufacturers of all other 
basic models distributed in commerce in the United States and known to 
Goodman to incorporate design characteristic(s) similar to those found 
in the basic models that are the subject of the petition.

IV. Grounds for Petition of Waiver

    Goodman notes that the federal test procedures in Appendix M and 
Appendix M1 do not include provisions to determine the following 
cooling air volume rates for ducted coil-only VSACs and VSHPs: Cooling 
minimum, cooling intermediate, and heating intermediate (limited to 
ducted coil-only VSHPs). Specifically, sections 3.1.4.2 on cooling 
minimum air volume rate, 3.1.4.3 on cooling intermediate air volume 
rate, and 3.1.4.6 on heating intermediate air volume rate in Appendix M 
and Appendix M1 do not include adequate procedures for testing ducted 
coil-only VSACs/VSHPs. However, determination of these cooling/heating 
air volume rates is essential to establishing performance metrics, 
determining and certifying compliance in accordance with DOE's current 
requirements.\4\ Although a coil-only represented value is not 
prohibited for ducted coil-only VSACs and VSHPs under 10 CFR 429.16(a) 
and the scopes of both Appendix M and Appendix M1 include such systems, 
the lack of coverage within the current test procedure to determine the 
cooling and heating air volume rates for such systems makes it 
impossible to make appropriate representations of performance metrics 
for these systems.\5\
---------------------------------------------------------------------------

    \4\ Energy conservation standards in 10 CFR part 430.32(c) and 
certification and compliance in accordance with 10 CFR part 429.
    \5\ Table 8 in Appendix M to Subpart B of 10 CFR part 430 
specifies cooling mode test conditions for units having a variable-
speed compressor, and these tests cannot be appropriately conducted 
without clear provisions pertaining to the three separate cooling 
air volume rates. Table 14 in Appendix M to Subpart B of 10 CFR part 
430 specifies heating mode test conditions for units having a 
variable-speed compressor, and these tests cannot be appropriately 
conducted without clear provisions pertaining to the three separate 
heating air volume rates.
---------------------------------------------------------------------------

    As described generally above, our VSACs and VSHPs, if used in a 
coil-only application, have design characteristics for which the 
Appendix M and Appendix M1 test procedures cannot accurately represent 
their true energy consumption. Therefore, using the current test 
procedures without a waiver would result in materially inaccurate 
comparative data. 10 CFR 429.27(a)(1) and 10 CFR 429.27(f)(2). The 
remainder of this section describes in detail the design 
characteristics that form the basis for our request for waiver and 
interim waiver.
    The basic models for which we request a test procedure waiver and 
interim waiver will require the use of [REDACTED]
    For these reasons, specifying Cooling Minimum Airflow Rate or 
Heating Minimum Airflow Rate, as appropriate for the cooling or heating 
intermediate and minimum tests, will ensure that the test procedure 
matches the true operation, and therefore the true energy consumption, 
of our systems when installed in a consumer's home.

    Just as with any new air conditioner or heat pump installation 
using an existing furnace \8\ the contractor who installs one of our 
VSAC or VSHP will need to determine the appropriate speed tap(s) of the 
existing furnace blower to connect to the furnace control. The airflow 
rates at which our systems will have certified performance will be 
published in both our technical literature and on the AHRI Directory of 
Certified Product Performance.\9\
---------------------------------------------------------------------------

    \8\ Regardless of whether the new air conditioner or heat pump 
is single-stage or two-stage.
    \9\ https://www.ahridirectory.org/Search/SearchHome.
---------------------------------------------------------------------------

    Many existing furnaces with permanent split capacitor (``PSC'') 
motors, which is presently most of the installation base, typically 
have four or five speed taps for the motors. Many furnaces Goodman 
manufactured for years \10\ had PSC motors with speed taps for ``hi,'' 
``med,'' ``med-low'' and ``low'' airflow rates. For ``high stage'' 
cooling/heating operation, most field applications of single-stage or 
two-stage air conditioners or heat pumps would use one of the higher 
speed taps (such as ``hi'' or ``med''). For application of our variable 
speed air conditioners or heat pumps, we would recommend using the same 
speed tap for the higher airflow as would be used for ``high stage'' of 
a two-stage unit or for single-stage.
---------------------------------------------------------------------------

    \10\ Prior to Fan Energy Rating (``FER'') rule that went into 
effect 7/3/2019.
---------------------------------------------------------------------------

    For ``low stage'' cooling/heating operation, most field 
applications of two-stage units would use the lowest or second lowest 
of the speed taps (such as ``low'' or ``med-low''). For application of 
our variable speed air conditioners or heat pumps, we would recommend 
using the same speed tap for the lower airflow as would be used for 
``low stage'' of a two-stage unit.
    This concludes the description of the design characteristics of our 
VSACs and VSHPs which render the current Appendix M and Appendix M1 
test procedures incapable of providing accurate and representative 
measures of their true energy consumption. The next section provides 
our suggested modifications to Appendix M and Appendix M1 that will 
provide accurate and representative test data for our VSAC and VSHP.

V. Proposed Alternate Test Procedures

    As required by 10 CFR 430.27(b)(iii), Goodman is providing the 
proposed revisions below to Appendix M and Appendix M1 as the 
alternative to evaluate the performance of the basic models listed in 
Appendix I of this petition.
    The alternate test procedures for the Goodman basic models 
identified in Appendix I of this petition are identical to the test 
procedures prescribed in Appendix M and Appendix M1. The exception is 
as described below, for coil-only combinations, the cooling minimum air 
volume rate as determined in section 3.1.4.2.c. of Appendix M and 
Appendix M1 shall be used as the cooling intermediate and cooling 
minimum air volume rates. The heating minimum air volume rate as 
determined in section 3.1.4.5.1.a.(3). of both Appendix M and Appendix 
M1 shall also be used as the heating intermediate air volume rate.\11\ 
All other requirements of Appendix M and Appendix M1 remain identical.
---------------------------------------------------------------------------

    \11\ Note that provisions in section 3.1.4.5.2.d. specific to 
ducted two-stage coil-only system northern heat pumps and ducted 
two-stage heating-only coil-only system heat pumps do not apply to 
the basic models addressed in this petition.
---------------------------------------------------------------------------

    In 3.1.4.2, Cooling Minimum Air Volume Rate, include the following:
    f. For ducted variable-speed compressor systems tested with a coil-
only indoor unit, the cooling minimum air volume rate is the higher of 
(1) the rate specified by the installation instructions included with 
the unit by the manufacturer or (2) 75 percent of the cooling full-load 
air volume rate. During the laboratory tests on a coil-only (fanless) 
system, obtain this cooling minimum air volume rate regardless of the 
pressure drop across the indoor coil assembly.
    In 3.1.4.3, Cooling Intermediate Air Volume Rate, include the 
following:
    d. For ducted variable-speed compressor systems tested with a coil-
only indoor unit, use the cooling minimum air volume rate as determined 
in 3.1.4.2(f), without regard to the pressure drop across the indoor 
coil assembly.
    In 3.1.4.6, Heating Intermediate Air Volume Rate (limited to ducted 
coil-only VSHPs), include the following:
    d. For ducted variable-speed compressor systems tested with a coil-
only indoor unit, use the heating minimum air volume rate as determined 
in 3.1.4.5.1.a.(3), without regard to the pressure drop across the 
indoor coil assembly.
    No alternate test procedure is being proposed for Cooling Full-load 
Air Volume Rate, Heating Minimum Air Volume Rate (limited to ducted 
coil-only VSHPs), and Heating Full-Load Air Volume Rate (limited to 
ducted coil-only VSHPs). Cooling Full-load Air Volume Rate will be 
determined using section 3.1.4.1.1.c. of the federal test procedures 
set forth in Appendix M and M1. Heating Minimum Air Volume Rate will be 
determined using section 3.1.4.5.1.a.(3) of the federal test procedures 
set forth in Appendix M and M1. Heating Full-load Air Volume Rate will 
be determined using section 3.1.4.4.1.a.(3) of the federal test 
procedures set forth in Appendix M and M1.

VI. Petition for Interim Waiver

    Pursuant to 10 CFR part 430.27(b)(2), Goodman also hereby applies 
for an interim waiver of the applicable test procedure requirements for 
the basic models listed in Appendix I of this petition.
    Goodman believes the petition for waiver is likely to be granted, 
as evidenced in Section I and Section IV of this document. Without 
waiver relief, Goodman would be subject to requirements under the 
current federal test procedure that would render it impossible for 
Goodman to make appropriate representations of performance metrics for 
the basic models listed in Appendix I of this petition, thereby 
precluding Goodman from distributing these basic models into commerce 
and limiting consumer choice and competition. Goodman respectfully 
requests DOE to consider this public policy aspect and grant immediate 
relief pending a determination on the petition for waiver, while also 
accounting for any similar decisions made in the past for other 
manufacturers on the same matter.
    Additionally, Goodman is likely to suffer economic hardship and a 
competitive disadvantage if DOE does not grant its interim waiver 
request. Absent an interim waiver, the basic models listed in Appendix 
I of this petition will continue to remain disadvantaged in the 
marketplace relative to other products. If Goodman must wait for 
completion of the waiver consideration and issuance process, it may 
well be forced to delay the opportunity to offer high efficiency, 
energy saving VSAC and VSHP models to U.S. consumers, as well as delay 
recouping production and marketing costs associated with introducing 
the basic models via product sales into the U.S. market.

VII. Concluding Remarks

    Goodman respectfully requests that DOE grant its petitions for 
waiver and interim waiver of the applicable test procedure for the 
specified basic models. Goodman requests expedited treatment of both 
the petitions and is willing to provide promptly any additional 
information DOE requires to

[[Page 40542]]

act expeditiously, as receipt of the waivers will facilitate Goodman's 
timely production of the applicable models for the upcoming cooling 
season. If you have any questions regarding Goodman's petitions for 
waiver and interim waiver, please do not hesitate to contact myself or 
Rusty Tharp, Senior Director of Regulatory Affairs (713/263-5906 or 
[email protected]).

Sincerely,
/s/

Appendix I

    The waiver and interim waiver requests apply to the following basic 
models. Note that for all coil-only systems, there is no indoor unit 
with fan.
