Air-Cooled Commercial Package Air Conditioners and Heat Pumps
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of
Energy.
ACTION: Direct final rule; confirmation of effective and compliance
dates.
-----------------------------------------------------------------------
SUMMARY: The U.S. Department of Energy (``DOE'') published a direct
final rule to establish amended energy conservation standards for air-
cooled commercial package air conditioners and heat pumps with a rated
cooling capacity greater than or equal to 65,000 Btu/h in the Federal
Register on May 20, 2024. DOE has determined that the comments received
in response to the direct final rule do not provide a reasonable basis
for withdrawing the direct final rule. Therefore, DOE provides this
document confirming the effective and compliance dates of those
standards.
DATES: The effective date of September 17, 2024, for the direct final
rule published on May 20, 2024, (89 FR 44052) is confirmed. Compliance
with the standards established in the direct final rule will be
required on and after January 1, 2029.

I. Authority
The Energy Policy and Conservation Act, Public Law 94-163, as
amended (``EPCA''),\1\ authorizes DOE to issue a direct final rule
establishing an energy conservation standard for covered equipment on
receipt of a statement submitted jointly by interested persons that are
fairly representative of relevant points of view (including
representatives of manufacturers of covered equipment, States, and
efficiency advocates), as determined by the Secretary of Energy
(``Secretary''), that contains recommendations with respect to an
energy or water conservation standard that are in accordance with the
provisions of 42 U.S.C. 6295(o) or 42 U.S.C. 6313(a)(6)(B), as
applicable. (42 U.S.C. 6316(b)(1); 42 U.S.C. 6295(p)(4))
---------------------------------------------------------------------------
\1\ 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), which reflect the last statutory amendments that impact
Parts A and A-1 of EPCA.
---------------------------------------------------------------------------
The direct final rule must be published simultaneously with a
notice of proposed rulemaking (``NOPR'') that proposes an energy or
water conservation standard that is identical to the standard
established in the direct final rule, and DOE must provide a public
comment period of at least 110 days on this proposal. (42 U.S.C.
6316(b)(1); 42 U.S.C. 6295(p)(4)(A)-(B)) Not later than 120 days after
issuance of the direct final rule, DOE shall withdraw the direct final
rule if: (1) DOE receives one or more adverse public comments relating
to the direct final rule or any alternative joint recommendation; and
(2) based on the rulemaking record relating to the direct final rule,
DOE determines that such adverse public comments or alternative joint
recommendation may provide a reasonable basis for withdrawing the
direct final rule. (42 U.S.C. 6316(b)(1); 42 U.S.C. 6295(p)(4)(C)) If
DOE makes such a determination, DOE must proceed with the NOPR
published simultaneously with the direct final rule and publish in the
Federal Register the reasons why the direct final rule was withdrawn.
(Id.)
After review of comments received, DOE has determined that it did
not receive any adverse comments providing a basis for withdrawal
described above for the direct final rule that is the subject of this
document. As such, DOE did not withdraw this direct final rule and
allowed it to become effective. Although not required under EPCA, where
DOE does not withdraw a direct final rule, DOE customarily publishes a
summary of the comments received during the 110-day comment period and
its responses to those comments. This document contains such a summary,
as well as DOE's responses to the comments.
II. Air-Cooled Commercial Unitary Air Conditioners and Heat Pumps
Direct Final Rule
A. Background
Small, large, and very large commercial package air conditioning
and heating equipment are covered equipment under EPCA. (42 U.S.C.
6311(1)(B)-(D)) Such equipment includes as equipment categories air-
cooled commercial unitary air conditioners with a rated cooling
capacity greater than or equal to 65,000 Btu/h and less than 760,000
Btu/h (``ACUACs'') and air-cooled commercial unitary heat pumps with a
rated cooling capacity greater than or equal to 65,000 Btu/h and less
than 760,000 Btu/h (``ACUHPs'') (excluding double-duct air conditioners
and heat pumps), which are the subject of this rulemaking.\2\
---------------------------------------------------------------------------
\2\ While ACUACs and ACUHPs with rated cooling capacity less
than 65,000 Btu/h are included in the broader category of commercial
unitary air conditioners and heat pumps (``CUACs and CUHPs''), they
are not addressed in this rulemaking. The standards for ACUACs and
ACUHPs with rated cooling capacity less than 65,000 Btu/h have been
addressed in a separate rulemaking (see Docket No. EERE-2022-BT-STD-
0008). Additionally, while double-duct air conditioners and heat
pumps are air-cooled commercial package air conditioning and heating
equipment, they are not addressed in this rulemaking. Double-duct
systems will be addressed in a separate rulemaking process.
Accordingly, all references within this direct final rule to ACUACs
and ACUHPs exclude equipment with rated cooling capacity less than
65,000 Btu/h and double-duct systems.
---------------------------------------------------------------------------
In a direct final rule published in the Federal Register on January
15, 2016 (``January 2016 Direct Final Rule''), DOE prescribed the
current energy conservation standards for ACUACs and ACUHPs
manufactured on and after January 1, 2023.\3\ 81 FR 2420. These
standards are set forth in DOE's regulations at title 10 of the Code of
Federal Regulations (``CFR'') section 431.97(b).
---------------------------------------------------------------------------
\3\ The January 2016 Direct Final Rule adopted a two-tiered
standard approach that applied a first tier of minimum efficiency
levels for compliance on January 1, 2018, and a second tier of
higher minimum efficiency levels for compliance on January 1, 2023.
81 FR 2420, 2489-2490, 2531 (Jan. 15, 2016).
---------------------------------------------------------------------------
DOE's current energy conservation standards are expressed in terms
of integrated energy efficiency ratio (``IEER'') for the cooling
efficiency of ACUACs and ACUHPs, and in terms of coefficient of
performance (``COP'') for the heating efficiency of ACUHPs. (See 10 CFR
431.97(b)) To demonstrate compliance with the current energy
conservation standards, manufacturers must use the test procedure
provided at 10 CFR part 431, subpart F, appendix A (``appendix A''),
Uniform Test Method for the Measurement of Energy Consumption of
Commercial Package Air Conditioning and Heating Equipment (Excluding
Air-Cooled Equipment With a Cooling Capacity Less Than 65,000 Btu/h).
Since publication of the January 2016 Direct Final Rule, the
American Society of Heating, Refrigerating, and Air-Conditioning
Engineers (``ASHRAE'') published an updated version of ASHRAE Standard
90.1 (``ASHRAE Standard 90.1-2016''), which updated the minimum
efficiency levels for ACUACs and ACUHPs to align with the first tier of
minimum efficiencies adopted by DOE in the January 2016 Direct Final
Rule (which had a compliance date of January 1, 2018). ASHRAE
subsequently published another updated version of ASHRAE Standard 90.1
(``ASHRAE Standard 90.1-2019''), which updated the minimum efficiency
levels for ACUACs and ACUHPs to align with both tiers adopted by DOE in
the January 2016 Direct Final Rule (i.e., specifying two tiers of
minimum levels for ACUACs and ACUHPs, with a January 1, 2023,
compliance date for the second tier).\4\
---------------------------------------------------------------------------
\4\ ASHRAE Standard 90.1-2022 was published in January 2023, but
it did not affect the standards being considered in this rulemaking
or trigger DOE for this equipment.
---------------------------------------------------------------------------
[[Page 79376]]
On May 12, 2020, DOE began its six-year-lookback review for ACUACs
and ACUHPs by publishing in the Federal Register an energy conservation
standards (``ECS'') request for information (``RFI'') (referred to
hereafter as the ``May 2020 ECS RFI'').\5\ 85 FR 27941. The May 2020
ECS RFI sought information to help DOE inform its decisions, consistent
with its obligations under EPCA. DOE received multiple comments from
interested stakeholders in response to the May 2020 ECS RFI, which
prompted DOE to publish a test procedure and energy conservation notice
RFI (referred to hereafter as the ``May 2022 TP/ECS RFI'') in the
Federal Register on May 25, 2022, to investigate additional aspects of
the ACUAC and ACUHP test procedure and energy conservation standards.
87 FR 31743.
---------------------------------------------------------------------------
\5\ The May 2020 ECS RFI also addressed commercial warm air
furnaces, a separate type of covered equipment which was
subsequently handled in a different rulemaking proceeding (see
Docket No. EERE-2019-BT-STD-0042 in www.regulations.gov).
---------------------------------------------------------------------------
On July 29, 2022, DOE published in the Federal Register a notice of
intent to establish a working group for commercial unitary air
conditioners and heat pumps to negotiate proposed test procedures and
amended energy conservation standards for this equipment (``July 2022
Notice of Intent''). 87 FR 45703. The Appliance Standards and
Rulemaking Federal Advisory Committee (``ASRAC'') established the ASRAC
ACUAC/HP Working Group (hereinafter referred to as ``the ACUAC/HP
Working Group'') in accordance with the Federal Advisory Committee Act
(``FACA'') (5 U.S.C. App 2) and the Negotiated Rulemaking Act (``NRA'')
(5 U.S.C. 561-570, Pub. L. 104-320). The purpose of the ACUAC/HP
Working Group was to discuss, and if possible, reach consensus on
recommended amendments to the test procedures and energy conservation
standards for ACUACs and ACUHPs. The ACUAC/HP Working Group consisted
of 14 voting members, including DOE. (See appendix A, Working Group
Members, Document No. 65 in Docket No. EERE-2022-BT-STD-0015) On
December 15, 2022, the ACUAC/HP Working Group signed a term sheet
(``ACUAC/HP Working Group TP Term Sheet'') of recommendations regarding
ACUAC and ACUHP test procedures, including two new efficiency metrics:
integrated ventilation, economizing, and cooling (``IVEC'') and
integrated ventilation and heating efficiency (``IVHE''). (See Id.)
The ACUAC/HP Working Group met five times to discuss energy
conservation standards for ACUACs and ACUHPs. These meetings took place
on February 22-23, March 21-22, April 12-13, April 26-27, and May 1,
2023. As a result of these efforts, the ACUAC/HP Working Group
successfully reached consensus on recommended energy conservation
standards in terms of the new IVEC and IVHE metrics for ACUACs and
ACUHPs. On May 1, 2023, the ACUAC/HP Working Group signed a term sheet
(``ACUAC/HP Working Group ECS Term Sheet'') outlining its
recommendations regarding ACUAC and ACUHP standards in terms of the new
efficiency metrics, IVEC and IVHE, which ASRAC approved on October 17,
2023.\6\
---------------------------------------------------------------------------
\6\ The ACUAC/HP Working Group ECS Term Sheet is available at
www.regulations.gov/document/EERE-2022-BT-STD-0015-0087.
---------------------------------------------------------------------------
DOE determined that the ACUAC/ACUHP Working Group statement
containing recommendations with respect to energy conservation
standards for ACUACs and ACUHPs were in accordance with the statutory
requirements of 42 U.S.C. 6295(p)(4)(A); 42 U.S.C. 6316(b)(1) for the
issuance of a direct final rule and published a direct final rule in
the Federal Register on May 20, 2024 (``May 2024 Direct Final Rule'').
89 FR 44052, 44064-44065. DOE simultaneously published a final rule in
the Federal Register amending the current test procedure, Appendix A,
to incorporate by reference the most recent version of the industry
test procedure, AHRI 340/360-2022, for ACUACs, ACUHPs, evaporatively-
cooled commercial unitary air conditioners (``ECUACs''), and water-
cooled commercial unitary air conditioners (``WCAUCs'') and
establishing a new test procedure appendix A1 to subpart F of 10 CFR
431.96 (``appendix A1'') referencing a new industry test procedure,
AHRI 1340-2023, for any standards denominated in terms of IVEC and
IVHE. (``May 2024 TP Final Rule''). 89 FR 43986 (May 20, 2024).
Accordingly, DOE adopted the recommended efficiency levels for ACUACs
and ACUHPs as the amended standard levels in the May 2024 Direct Final
Rule. 89 FR 44052, 44135 (May 20, 2024).
The standards adopted in the May 2024 Direct Final Rule apply to
the equipment classes listed in table II.1 and that are manufactured
in, or imported into, the United States starting on January 1, 2029.
The May 2024 Direct Final Rule provides a detailed discussion of DOE's
analysis of the benefits and burdens of the amended standards pursuant
to the criteria set forth in EPCA. Id. at 89 FR 44124-44134.

As required by EPCA, DOE also simultaneously published a NOPR
proposing the identical standard levels contained in the May 2024
Direct Final Rule. 89 FR 43770 (May 20, 2024). DOE considered whether
any adverse
[[Page 79377]]
comment received during the 110-day comment period following the
publication of the May 2024 Direct Final Rule provided a reasonable
basis for withdrawal of the direct final rule under the provisions in
42 U.S.C. 6295(p)(4)(C) and 42 U.S.C. 6316(b)(1).
III. Comments on the Direct Final Rule
As discussed in section I of this document, not later than 120 days
after publication of a direct final rule, DOE shall withdraw the direct
final rule if: (1) DOE receives one or more adverse public comments
relating to the direct final rule or any alternative joint
recommendation; and (2) based on the rulemaking record relating to the
direct final rule, DOE determines that such adverse public comments or
alternative joint recommendation may provide a reasonable basis for
withdrawing the direct final rule. (42 U.S.C. 6316(b)(1); 42 U.S.C.
6295(p)(4)(C)(i))
DOE received comments in response to the May 2024 Direct Final Rule
from the interested parties listed in table III.1.

Therefore, both comment submissions are included in this table.
A parenthetical reference at the end of a comment quotation or
paraphrase provides the location of the item in the public record.\7\
The following sections discuss the substantive comments DOE received on
the May 2024 Direct Final Rule, as well as DOE's determination that the
comments do not provide a reasonable basis for withdrawal of the direct
final rule.
---------------------------------------------------------------------------
\7\ The parenthetical reference provides a reference for
information located in the docket of DOE's rulemaking to develop
energy conservation standards for the subject ACUACs and ACUHPs.
(Docket No. EERE-2022-BT-STD-0015, which is maintained at:
www.regulations.gov). The references are arranged as follows:
(commenter name, comment docket ID number at page of that document).
---------------------------------------------------------------------------
A. General Comments
ASAP, ACEEE, and NEEA and the CA IOUs supported the standards in
the May 2024 Direct Final Rule, as they align with the levels
prescribed in Recommendation #1 of the ACUAC/HP Working Group ECS Term
Sheet. (ASAP, ACEEE, and NEEA, No. 106 at p. 1; CA IOUs, Nos. 104 and
105 at pp. 1-2) The CA IOUs supported the effective date of January 1,
2029, for these standards. (CA IOUs, Nos. 104 and 105 at p. 2)
ASAP, ACEEE, and NEEA commented that the new efficiency metrics,
IVEC and IVHE, would improve the representativeness of the efficiency
ratings and better capture the total energy consumption of the cooling
and heating seasons. (ASAP, ACEEE, and NEEA, No. 106 at p. 1) ASAP,
ACEEE, and NEEA commented that the standards would reduce national
energy consumption, cut carbon emissions, and provide net present value
savings for consumers. (Id.) ASAP, ACEEE, and NEEA commented that
small-capacity ACUACs have the largest market share and would use
almost 23 percent less energy with the amended standards than ones just
meeting the current standard. (Id.) ASAP, ACEEE, and NEEA further
commented that the amended standards would provide large life-cycle
cost savings for consumers, with short payback periods relative to the
lifetime of ACUACs and ACUHPs. (Id. at p. 2)
Anderson supported the May 2024 Direct Final Rule, stating that it
would be the next step towards greater energy efficiency and emissions
reductions and that it would drive innovation to support economic
savings and a more sustainable environment. (Anderson, No. 102 at p. 1)
DOE agrees with these comments which are in accord with the amended
standards set forth in the May 2024 Direct Final Rule.
An anonymous commenter stated that ASHRAE 241 standards or better
must be adopted. (Anonymous, No. 103 at p. 1)
In response to the anonymous commenter, ASHRAE Standard 241,
Control of Infectious Aerosols, (``ASHRAE 241'') addresses the design,
installation, commissioning, and maintenance of HVAC systems to control
the spread of infectious aerosols. As such, the provisions of ASHRAE
241 are outside the scope of consideration for this rulemaking.
Therefore, DOE has determined that the comment regarding adoption of
ASHRAE 241 provided by this anonymous commenter does not provide a
reasonable basis to withdraw the May 2024 Direct Final Rule.
B. Certification
The CA IOUs urged DOE to initiate a certification rulemaking at its
earliest convenience such that Recommendation #2 of the ACUAC/HP
Working Group ECS Term Sheet could be implemented allowing for
certification of ACUACs and ACUHPs using the new metrics and reporting
fields. (CA IOUs, No. 104 and 105 at p. 2) The CA IOUs specifically
requested that manufacturers publicly certify the crankcase heat
wattage for each compressor stage, and the 5 [deg]F heating capacity
and COP, if applicable. (Id.) The CA IOUs commented that the early
implementation of a certification rulemaking would clarify the
certification requirements and process and facilitate early compliance
for manufacturers before the amended standards' effective date of
January 1, 2029. (Id.)
In response, DOE acknowledges that certification data will be
required for ACUACs and ACUHPs; however, DOE did not amend the existing
or adopt new certification or reporting requirements for ACUACs and
ACUHPs in the May 2024 Direct Final Rule. 89 FR 44052, 44132 (May 20,
2024). Instead, DOE may consider proposals to establish associated
certification requirements and reporting for ACUACs and ACUHPs under a
separate, future rulemaking regarding appliance and equipment
certification.
[[Page 79378]]
IV. Impact of Any Lessening of Competition
EPCA directs DOE to consider the impact of any lessening of
competition, as determined in writing by the Attorney General of the
United States (``Attorney General''), that is likely to result from a
standard. (42 U.S.C. 6316(b)(1); 42 U.S.C. 6295(p)(4)(A)(i); 42 U.S.C.
6313(a)(6)(B)(ii)(V)) To assist the Attorney General in making this
determination, DOE provided the Department of Justice (``DOJ'') with
copies of the May 2024 Direct Final Rule, the corresponding NOPR, and
the May 2024 DirectFinal Rule Technical Support Document for review.
DOE has published DOJ's comments at the end of this document in
appendix A.
In its letter responding to DOE, DOJ concluded that, based on its
review, the proposed energy conservation standards in the Direct Final
Rule are unlikely to have a significant adverse impact on competition.
V. Conclusion
In summary, based on the previous discussion, DOE has determined
that the comments received in response to the direct final rule for
amended energy conservation standards for the subject ACUACs and ACUHPs
do not provide a reasonable basis for withdrawal of the direct final
rule. As a result, the energy conservation standards set forth in the
direct final rule became effective on September 17, 2024. Compliance
with these standards is required on and after January 1, 2029.
