 Department of Energy [Case Number 2023-005; EERE-2023-BT-WAV-0018]
 AGENCY: Office of Energy Efficiency and Renewable Energy, Department of Energy.
 ACTION: Notification of petition for waiver and grant of an interim waiver; request for comments.
 SUMMARY: This notification announces receipt of and publishes a petition for waiver and interim waiver from Johnson Controls Inc. (“JCI”), which seeks a waiver for specified basic models of central air conditioners (“CACs”) and central air conditioning heat pumps (“HPs”) (collectively, “CAC/HPs”) from the U.S. Department of Energy (“DOE”) test procedure used for determining the efficiency of CAC/HPs. According to JCI, testing its CAC/HP basic models that use variable-speed, oil-injected scroll compressors with only a 20-hour break-in period produces results unrepresentative of their true energy consumption characteristics, and would provide materially inaccurate comparative data. JCI requested that in lieu of the 20-hour break-in limit, it be permitted to test the specified CAC/HP basic models with a 72-hour break-in period. DOE also gives notification of an Interim Waiver Order that requires JCI to test and rate the specified CAC/HP basic models in accordance with the alternate test procedure set forth in the Interim Waiver Order. DOE solicits comments, data, and information concerning JCI's petition and its suggested alternate test procedure so as to inform DOE's final decision on JCI's waiver request.
 DATES: Written comments and information are requested and will be accepted on or before November 20, 2023.

Case Number 2023-005 Interim Waiver Order I. Authority and Background The Energy Policy and Conservation Act, as amended (“EPCA”),[2]
                    
                     authorizes the U.S. Department of Energy (“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 B of EPCA [3]
                    
                     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 CAC/HPs, the subject of this document. (42 U.S.C. 6292(a)(3)) 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 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 
                    ( print page 72451)
                    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 test procedure for CAC/HPs is contained in the Code of Federal Regulations (“CFR”) at 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, 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). 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 to that effect. 
                    *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)(3). 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). If the interim waiver test procedure methodology is different than the decision and order test procedure methodology, certification reports to DOE required under 10 CFR 429.12 and any representations must be based on either of the two methodologies until 180 days after the publication date of the decision and order. Thereafter, certification reports and any representations must be based on the decision and order test procedure methodology, unless otherwise specified by DOE. 10 CFR 430.27(i)(1). When DOE amends the test procedure to address the issues presented in a waiver, the waiver or interim waiver will automatically terminate on the date on which use of that test procedure is required to demonstrate compliance. 10 CFR 429.27(h)(3). II. JCI's Petition for Waiver and Interim Waiver On July 12, 2023, DOE received from JCI a petition for waiver and interim waiver from the test procedure for CAC/HPs set forth at 10 CFR part 430, subpart B, appendix M1.[4]
                    
                     (JCI, No. 1 at pp. 1-10) [5]
                    
                     Pursuant to 10 CFR 430.27(e)(1), DOE posted the petition on the DOE website at: 
                    *www.energy.gov/​eere/​buildings/​current-test-procedure-waivers.*
                     The petition did not identify any of the information contained therein as confidential business information. According to JCI, testing its CAC/HP basic models that use variable-speed, oil-injected scroll compressors (“VSS systems”) with only a 20-hour break-in period produces results unrepresentative of their true energy consumption characteristics, and would provide materially inaccurate comparative data. (JCI, No. 1 at p. 1) JCI requested that in lieu of the 20-hour break-in limit, it be permitted to test its VSS systems with a 72-hour break-in period. 
                    *Id.*
                     Consequently, JCI seeks to use an alternate test procedure to test and rate specific CAC/HP basic models, which increases the break-in time limit stipulated in section 3.1.7 of appendix M1. 
                    *Id.* On March 23, 2018, DOE granted JCI a waiver from DOE's then effective CAC/HP test procedure [6]
                    
                     for these same basic models of VSS systems, permitting them to test with a 72-hour break-in period. 83 FR 12735. DOE notes that the alternative test procedure requested by JCI in this waiver petition for appendix M1 is identical to the alternative test procedure included in the waiver it previously obtained under appendix M. JCI also requested an interim waiver from the existing DOE test procedure, noting that DOE previously granted JCI an interim waiver under appendix M regarding the allowable break-in period for these same models in 2017.[7]
                    
                     (JCI, No. 1 at pp. 7-8) Absent an interim waiver, JCI asserted that its VSS systems will continue to be at a competitive disadvantage on the market and consumers will continue to be exposed to materially inaccurate information about the energy consumption characteristics of its VSS systems. 
                    *Id.*
                     As the circumstances surrounding JCI's request for an interim waiver and the products and models subject to the waiver have not changed, JCI asserted that an identical interim waiver is warranted. 
                    *Id.*
                     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)(3). 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 covered 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 
                    ( print page 72452)
                    may establish in a subsequent Decision and Order an alternate test procedure for the basic models addressed by the Interim Waiver Order. JCI seeks to use an alternate test procedure to test and rate specific CAC/HP basic models of VSS systems consistent with the waiver it previously obtained for these same basic models under appendix M.[8]
                    
                     (JCI, No. 1 at pp. 6-7) In its petition, JCI proposed to test and rate its specified basic models according to the test procedure prescribed by DOE at 10 CFR part 430, subpart B, appendix M1, except that the 20-hour break-in period maximum in section 3.1.7 of appendix M1 be replaced with a 72-hour maximum. 
                    *Id.*
                     Under JCI's proposed alternative test procedure, the following language would be used instead of section 3.1.7 of appendix M1: 3.1.7 Test Sequence Manufacturers may optionally operate the equipment under test for a “break-in” period, not to exceed 72 hours, prior to conducting the test method specified in this section. A manufacturer who elects to use this optional compressor break-in period in its certification testing should record this information (including the duration) in the test data underlying the certified ratings that are required to be maintained under 10 CFR 429.71. When testing a ducted unit (except if a heating-only heat pump), conduct the A or A2
                     Test first to establish the cooling full-load air volume rate. For ducted heat pumps where the heating and cooling full-load air volume rates are different, make the first heating mode test one that requires the heating full-load air volume rate. For ducted heating-only heat pumps, conduct the H1 or H12
                     Test first to establish the heating full-load air volume rate. When conducting a cyclic test, always conduct it immediately after the steady-state test that requires the same test conditions. For variable-speed systems, the first test using the cooling minimum air volume rate should precede the Ev
                     Test, and the first test using the heating minimum air volume rate must precede the H2v
                     Test. The test laboratory makes all other decisions on the test sequence. IV. Interim Waiver Order DOE has reviewed JCI's application for an interim waiver, the alternate test procedure requested by JCI, and the test data provided by JCI. DOE tentatively agrees that the circumstances surrounding JCI's request for an interim waiver and the products and models subject to the waiver have not changed since the granting of a similar waiver for testing to appendix M. Specifically, DOE has tentatively determined that the test data provided by JCI demonstrates that the specified VSS system models that are the subject of the waiver have compressors that may require more than the 20 hours of break-in time allowed by appendix M1. The oil injected into the oil-injected scroll compressors increases the coverage of the viscous oil layer between mating surfaces of the scroll. This is presumably its purpose, 
                    *i.e.,*
                     to provide additional sealing in the gaps of the mating surfaces to improve compressor volumetric efficiency (relationship between displacement rate and volume flow rate of refrigerant drawn into the compressor). By enhancing this oil layer, the direct contact between irregularities in the surfaces may also be reduced, which would slow the wearing process that smooths out these irregularities, which is the break-in process. For this reason, oil injected compressors are expected to require additional break-in time. DOE understands that absent a waiver, JCI's products cannot be tested and rated for energy consumption on a basis representative of their true energy consumption characteristics. DOE has initially determined that the alternate test procedure appears to allow for the accurate measurement of the energy efficiency of the specified basic models, while alleviating the testing problems cited by JCI in implementing the DOE test procedure for these basic models. Consequently, DOE has determined that JCI's petition for waiver likely will be granted. Furthermore, DOE has determined that it is desirable for public policy reasons to grant JCI immediate relief pending a determination of the petition for waiver. For the reasons stated, it is 
                    *ordered*
                     that: (1) JCI must test and rate the following CAC/HP basic models that use certain variable-speed, oil-injected scroll compressors with the alternate test procedure set forth in paragraph (2). York

 (2) The alternate test procedure for the JCI basic models identified in paragraph (1) of this Interim Waiver Order is the test procedure for CAC/HPs prescribed by DOE at 10 CFR 430, subpart B, appendix M1 except that the maximum duration of the break-in period is increased from 20 hours to 72 hours, as detailed below. All other requirements of appendix M1 and DOE's regulations remain applicable. In 3.1.7, 
                    *Test Sequence,*
                     test using these instructions: Manufacturers may optionally operate the equipment under test for a “break-in” period, not to exceed 72 hours, prior to conducting the test method specified in this section. A manufacturer who elects to use this optional compressor break-in period in its certification testing should record this information (including the duration) in the test data underlying the certified ratings that are required to be maintained under 10 CFR 429.71. When testing a ducted unit (except if a heating-only heat pump), conduct the A or A2
                     Test first to establish the cooling full-load air volume rate. For ducted heat pumps where the heating and cooling full-load air volume rates are different, make the first heating mode test one that requires the heating full-load air volume rate. For ducted heating-only heat pumps, conduct the H1 or H12
                     Test first to 
                    ( print page 72453)
                    establish the heating full-load air volume rate. When conducting a cyclic test, always conduct it immediately after the steady-state test that requires the same test conditions. For variable-speed systems, the first test using the cooling minimum air volume rate should precede the Ev
                     Test, and the first test using the heating minimum air volume rate must precede the H2v
                     Test. The test laboratory makes all other decisions on the test sequence. (3) 
                    *Representations.*
                     JCI may not make representations about the efficiency of a basic model listed in paragraph (1) of this Interim Waiver Order 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, test data, and documentary materials provided by JCI are valid. If JCI 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 JCI 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 waiver at any time if it determines the factual basis underlying the petition for the Interim Waiver Order is incorrect, or the results from the alternate test procedure are unrepresentative of the basic model's true energy consumption characteristics. 10 CFR 430.27(k)(1). Likewise, JCI may request that DOE rescind or modify the Interim Waiver Order if JCI 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 430.27(k)(2). (6) Issuance of this Interim Waiver Order does not release JCI 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. JCI may submit a new or amended petition for waiver and request for grant of interim waiver, as appropriate, for additional basic models of CAC/HPs. Alternatively, if appropriate, JCI 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). Signing Authority This document of the Department of Energy was signed on October 16, 2023 by Jeffrey Marootian, Principal Deputy Assistant Secretary for Energy Efficiency and Renewable Energy, pursuant to delegated authority from the Secretary of Energy.
