specifically set out in the request, not future models that may be 
manufactured by the petitioner. AHT may submit a new or amended 
petition for waiver and request for grant of interim waiver, as 
appropriate, for additional basic models of CRE. Alternatively, if 
appropriate, AHT may request that DOE extend the scope of a waiver or 
interim waiver to include additional basic models employing the same

Case Number 2020-023

Extension of Interim Waiver

I. Background and Authority

    The Energy Policy and Conservation Act, as amended (``EPCA''),\2\ 
authorizes DOE to regulate the energy efficiency of a number of 
consumer products and certain industrial equipment. (42 U.S.C. 6291-
6317) Title III, Part C \3\ of EPCA established the Energy Conservation 
Program for Certain Industrial Equipment, which sets forth a variety of 
provisions designed to improve energy efficiency for certain types of 
industrial equipment. This equipment includes Commercial Refrigerators, 
Freezers, and Refrigerator-Freezers (collectively ``commercial 
refrigeration equipment'' or ``CRE''), the focus of this document. (42 
U.S.C. 6311(1)(E))
---------------------------------------------------------------------------

    \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 C was redesignated as Part A-1.
---------------------------------------------------------------------------

    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. 6311), energy 
conservation standards (42 U.S.C. 6313), test procedures (42 U.S.C. 
6314), labeling provisions (42 U.S.C. 6315), and the authority to 
require information and reports from manufacturers (42 U.S.C. 6316).
    The Federal testing requirements consist of test procedures that 
manufacturers of covered equipment must use as the basis for: (1) 
Certifying to DOE that their equipment complies with the applicable 
energy conservation standards adopted pursuant to EPCA (42 U.S.C. 
6316(a); 42 U.S.C. 6295(s)), and (2) making representations about the 
efficiency of that equipment (42 U.S.C. 6314(d)). Similarly, DOE must 
use these test procedures to determine whether the equipment complies 
with relevant standards promulgated under EPCA. (42 U.S.C. 6316(a); 42 
U.S.C. 6295(s))
    Under 42 U.S.C. 6314, EPCA sets forth the criteria and procedures 
DOE is required to follow when prescribing or amending test procedures 
for covered equipment. 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 covered equipment during a 
representative average use cycle and requires that test procedures not 
be unduly burdensome to conduct. (42 U.S.C.6314(a)(2)) The test 
procedure for CRE is contained in 10 CFR part 431, subpart C, appendix 
B--Amended Uniform Test Method for the Measurement of Energy 
Consumption of Commercial Refrigerators, Freezers, and Refrigerator-
Freezers (``Appendix B'').
    Any interested person may submit a petition for waiver from DOE's 
test procedure requirements. 10 CFR 431.401(a)(1). 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 or water consumption 
characteristics as to provide materially inaccurate comparative data. 
10 CFR 431.401(f)(2). DOE may grant the waiver subject to conditions, 
including adherence to alternate test procedures. Id.
    A petitioner 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. 10 
CFR 431.401(g). DOE will publish any such extension in the Federal 
Register. Id.

II. Request for an Extension of Interim Waiver: Assertions and 
Determinations

    On May 26, 2017, DOE issued an Interim Waiver in Case Number CR-006 
granting AHT an interim waiver to test its AHT basic models specified 
in that interim waiver using an alternate test procedure. 82 FR 24330 
(``May 2017 Interim Waiver'').\4\ AHT stated that their basic models 
defrost less frequently than once every 24 hours. The DOE test 
procedure, by reference to ANSI/ASHRAE Standard 72-2005, ``Method of 
Testing Commercial Refrigerators and Freezers'' (``ASHRAE 72-2005''), 
requires beginning the test period at the start of a defrost cycle and 
recording data for 24 hours. AHT stated that the DOE test procedure 
would overstate the energy usage from the defrosting function. 82 FR 
24330, 24335.
---------------------------------------------------------------------------

    \4\ In the May 2017 Interim Waiver DOE declined to grant AHT an 
interim waiver as it pertained to AHT's petition regarding multi-
mode operation. 82 FR 24330, 24332. That denial is not relevant to 
AHT's request for an extension or this Order extending the interim 
waiver granted in the May 2017 Interim Waiver.
---------------------------------------------------------------------------

    Based on its review, including the information provided by AHT, DOE 
initially determined that the current test procedure at Appendix B 
would evaluate the CRE basic models specified in the May 2017 Interim 
Waiver in a manner so unrepresentative of their true energy consumption 
characteristics as to provide materially inaccurate comparative data. 
Id. at 82 FR 24332-24333. The May 2017 Interim Waiver specifies that 
AHT must test and rate the subject basic models such that the energy 
consumption be determined using an equation that incorporates the 
energy consumption of two modified tests. The first modified test would 
be a 24-hour test without a defrost cycle starting in steady state 
conditions with eight hours of door openings. The second modified test 
would include a defrost cycle starting after steady state conditions 
are established and continuing until the defrost cycle recovery is 
complete. Id. at 82 FR 24333.
    On November 12, 2020, AHT submitted a request to extend the scope 
of the interim waiver, Case Number 2020-023, to the specified 
additional AHT basic models.\5\ AHT stated that

[[Page 34729]]

these basic models have the same characteristics as the models covered 
by the existing interim waiver.
---------------------------------------------------------------------------

    \5\ The specified basic models are: IBIZA 100 (U) NAM-R, IBIZA 
100 (U) NAM-IC, IBIZA 145 (U) NAM-R, IBIZA 145 (U) NAM-IC, IBIZA 210

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

    DOE has reviewed AHT's interim waiver extension request and 
determined that the CRE basic models identified in AHT's request 
incorporate the same design characteristics as those basic models 
covered under the interim waiver in Case Number CR-006 such that the 
test procedure evaluates these basic models in a manner that is 
unrepresentative of their actual energy use. For the same reasons set 
forth in the May 2017 Interim Waiver, DOE understands that the model 
lines identified in AHT's request are not capable of defrosting once 
every 24 hours as simulated by the DOE test procedure. See 82 FR 24330, 
24332-24333. Accordingly, DOE is extending the interim waiver in Case 
Number CR-006 to the CRE basic models identified by AHT in its interim 
waiver extension request.

III. Order

    After careful consideration of all the material submitted by AHT in 
this matter, it is ordered that:
    (1) AHT must, as of the date of publication of this Extension of 
Interim Waiver in the Federal Register, test and rate the following AHT 
brand commercial refrigerator and commercial ice-cream freezer basic 
models with the alternate test procedure as set forth in paragraph (2):

    (2) The alternate test procedure for the AHT basic models 
referenced in paragraph (1) of this Order is the test procedure for CRE 
prescribed by DOE at 10 CFR part 431, subpart C, appendix B, except the 
test period shall be selected as follows:
    The first part of the test shall be a 24-hour test starting in 
steady-state conditions and including eight hours of door opening 
(according to ASHRAE Standard 72). The energy consumed in this test, 
ET1, shall be recorded.
    The second part of the test shall be a defrost cycle, including any 
operation associated with a defrost. The start and end points of the 
defrost cycle test period shall be determined according to the 
instructions for consumer refrigerators and refrigerator-freezers 
outlined in 10 CFR part 430, subpart B, appendix A, section 4.2.1.1 
(for cycling compressor systems) or section 4.2.1.2 (for non-cycling 
compressor systems). The energy consumed in this test, ET2, and 
duration, tDI, shall be recorded.
    Based on the measured energy consumption in these two tests, the 
daily energy consumption (DEC) in kWh shall be calculated as:

[[Page 34730]]

[GRAPHIC] [TIFF OMITTED] TN30JN21.000

Where:

DEC = daily energy consumption, kWh;
ET1 = energy consumed during the first part of the test, in kWh;
ET2 = energy consumed during the second part of the test, in kWh
tNDI = normalized length of defrosting time per day, in minutes;
tDI = length of time of defrosting test period, in minutes;
3.5 = time between defrost occurrences, in days; and
1440 = conversion factor, minutes per day.

    (3) Representations. AHT may not make representations about the 
energy use of a basic model listed in paragraph (1) of this Order for 
compliance, marketing, or other purposes unless that basic model has 
been tested in accordance with the provisions of paragraph (2) of this 
Order and such representations fairly disclose the results of such 
testing.
    (4) This Extension of Interim Waiver shall remain in effect 
according to the provisions of 10 CFR 431.401.
    (5) This Extension of Interim Waiver is issued on the condition 
that the statements, representations, and documentation provided by AHT 
are valid. If AHT makes any modifications to the defrost controls of 
these basic models, the interim waiver will no longer be valid and AHT 
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 Extension of Interim Waiver (and/or the underlying Order 
issued in Case Number CR-006) at any time if it determines the factual 
basis underlying the petition for extension of interim waiver (and/or 
the underlying Order issued in Case Number CR-006) is incorrect, or the 
results from the alternate test procedure are unrepresentative of a 
basic model's true energy consumption characteristics. 10 CFR 
431.401(k)(1). Likewise, AHT may request that DOE rescind or modify the 
Extension of Interim Waiver (and/or the underlying Order issued in Case 
Number CR-006) if AHT discovers an error in the information provided to 
DOE as part of its petition, determines that the interim waiver is no 
longer needed, or for other appropriate reasons. 10 CFR 431.401(k)(2).
    (6) AHT remains obligated to fulfill all applicable requirements 
set forth at 10 CFR part 429.
