Final determination.
The Energy Policy and Conservation Act (“EPCA”), as amended, prescribes energy conservation standards for various consumer products and certain commercial and industrial equipment, including evaporatively-cooled commercial package air conditioners and water-cooled commercial package air conditioners (referred to as evaporatively-cooled commercial unitary air conditioners (“ECUACs”) and water-cooled commercial unitary air conditioners (“WCUACs”) in this document). EPCA also requires the U.S. Department of Energy (“DOE”) to periodically determine whether more stringent, amended standards would result in significant additional conservation of energy, be technologically feasible, and be economically justified. In this final determination, DOE has determined that more stringent standards for small (cooling capacity less than 135,000 Btu/h), large (cooling capacity greater than or equal to 135,000 and less than 240,000 Btu/h), and very large (cooling capacity greater than or equal to 240,000 and less than 760,000 Btu/h) ECUACs and WCUACs would not result in significant additional conservation of energy, and thus has determined that the standards for ECUACs and WCUACs do not need to be amended.
The effective date of this final determination is July 14, 2021.

Title III, Part C
DOE is issuing this final determination pursuant to the EPCA requirement that not later than 6 years after issuance of any final rule establishing or amending an energy conservation standard for covered equipment, DOE must publish either a notice of determination that standards for the equipment do not need to be amended, or a notice of proposed rulemaking (“NOPR”) including new proposed energy conservation standards (proceeding to a final rule, as appropriate). (42 U.S.C. 6316(a)(6)(C)(i))
For this final determination, DOE analyzed the ECUACs and WCUACs subject to the standards found at title 10 of the Code of Federal Regulations (“CFR”) part 431.
The following section briefly discusses the statutory authority underlying this final determination, as well as some of the relevant historical background related to the establishment of standards for ECUACs and WCUACs.
EPCA authorizes DOE to regulate the energy efficiency of a number of consumer products and certain industrial equipment. Title III, Part C of EPCA, added by Public Law 95–619, Title IV, 441(a) (42 U.S.C. 6311–6317, as codified), established the Energy Conservation Program for Certain Industrial Equipment, which sets forth a variety of provisions designed to improve energy efficiency. This includes the ECUACs and WCUACs that are the subject of this final determination. (42 U.S.C. 6311(1)(B)–(D))
The energy conservation program under EPCA consists essentially of four parts: (1) Testing, (2) labeling, (3) the establishment of Federal energy conservation standards, and (4) certification and enforcement procedures. Relevant provisions of EPCA specifically 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).
Federal energy conservation requirements for covered equipment established under EPCA generally supersede state laws and regulations concerning energy conservation testing, labeling, and standards. (42 U.S.C. 6316(a) and (b); 42 U.S.C. 6297) DOE may, however, grant waivers of Federal preemption in limited instances for particular state laws or regulations, in accordance with the procedures and other provisions set forth under EPCA. (See 42 U.S.C. 6316(b)(2)(D) applying the preemption waiver provisions of 42 U.S.C. 6297).
EPCA contains mandatory energy conservation standards for commercial heating, air-conditioning, and water-heating equipment. (42 U.S.C. 6313(a)) Specifically, the statute sets standards for small, large, and very large commercial package air conditioning and heating equipment, packaged terminal air conditioners (“PTACs”) and packaged terminal heat pumps (“PTHPs”), warm-air furnaces, packaged boilers, storage water heaters, instantaneous water heaters, and unfired hot water storage tanks. (
If ASHRAE Standard 90.1 is amended with respect to the standard levels or design requirements applicable under that standard for certain commercial equipment, including ECUACs and WCUACs, not later than 180 days after the amendment of the standard, DOE must publish in the
To determine whether a standard is economically justified, EPCA requires that DOE determine whether the benefits of the standard exceed its burdens by considering, to the greatest extent practicable, the following seven factors:
(1) The economic impact of the standard on the manufacturers and consumers of the affected products;
(2) The savings in operating costs throughout the estimated average life of the product compared to any increases in the initial cost, or maintenance expenses;
(3) The total projected amount of energy and water (if applicable) savings likely to result directly from the standard;
(4) Any lessening of the utility or the performance of the products likely to result from the standard;
(5) The impact of any lessening of competition, as determined in writing by the Attorney General, that is likely to result from the standard;
(6) The need for national energy and water conservation; and
(7) Other factors the Secretary of Energy (“Secretary”) considers relevant.
(42 U.S.C. 6313(a)(6)(B)(ii)(I)–(VII))
If DOE decides to adopt, as a uniform national standard, the efficiency levels specified in the amended ASHRAE Standard 90.1, DOE must establish such standard not later than 18 months after publication of the amended industry standard. (42 U.S.C. 6313(a)(6)(A)(ii)(I)) However, if DOE determines, supported by clear and convincing evidence, that a more stringent uniform national standard would result in significant additional conservation of energy and is technologically feasible and economically justified, then DOE must establish the more stringent standard not later than 30 months after publication of the amended ASHRAE Standard 90.1. (42 U.S.C. 6313(a)(6)(A)(ii)(II) and (B)(i))
EPCA also requires that every six years DOE evaluate the energy conservation standards for certain commercial equipment, including ECUACs and WCUACs, and publish either a notice of determination that the standards do not need to be amended, or a NOPR that includes new proposed energy conservation standards (proceeding to a final rule, as appropriate). (42 U.S.C. 6313(a)(6)(C)(i)) EPCA further provides that, not later than three years after the issuance of a final determination to not amend standards, DOE must publish either a notice of determination that standards for the product do not need to be amended, or a NOPR including new proposed energy conservation standards (proceeding to a final rule, as appropriate). (42 U.S.C. 6313(a)(6)(C)(iii)(II)) DOE must make the analysis on which the determination is based publicly available and provide an opportunity for written comment. (42 U.S.C. 6313(a)(6)(C)(ii)) Further, a determination that more stringent standards would (1) result in significant additional conservation of energy, (2) be technologically feasible and (3) economically justified must be supported by clear and convincing evidence. (42 U.S.C. 6313(a)(6)(C)(i); 42 U.S.C. 6313(a)(6)(A).) A determination that amended energy conservation standards are not needed must be based on the same considerations as if it were adopting a standard that is more stringent than an amendment to ASHRAE Standard 90.1. (42 U.S.C. 6313(a)(6)(C)(i)(I); 42 U.S.C. 6313(a)(6)(B))
DOE is publishing this final determination pursuant to the six-year review required by EPCA, having determined that amended standards for ECUACs and WCUACs would not result in significant additional conservation of energy, be technologically feasible, and be economically justified.
The current energy conservation standards for ECUACs and WCUACs are located in Table 1 of 10 CFR 431.97. These standards and their compliance dates are presented in Table II.1 of this document. The current efficiency metric used for ECUACs and WCUACs is the energy efficiency ratio (“EER”).
On October 29, 2010, ASHRAE updated ASHRAE Standard 90.1 with respect to small, large, and very large commercial package air conditioning and heating equipment (
In a final rule published May 16, 2012, DOE amended the standards for ECUACs and WCUACs by adopting EER levels for this equipment established in ASHRAE 90.1–2010. 77 FR 28928 (“May 2012 final rule”). For certain small (
Based on its analysis and the review of the market, DOE determined that it did not have “clear and convincing evidence” that significant additional conservation of energy would result from adoption of more stringent standard levels than those in ASHRAE 90.1–2010 for ECUACs and WCUACs. 77 FR 28928, 28979. DOE did not conduct an economic analysis of standards more stringent than the ASHRAE 90.1–2010 levels for ECUACs and WCUACs because of the conclusion that more stringent standards would result in minimal energy savings.
Since ASHRAE 90.1–2010 was published, ASHRAE 90.1 has undergone three revisions. On October 9, 2013, ASHRAE published ASHRAE 90.1–2013; on October 26, 2016, ASHRAE published ASHRAE 90.1–2016; and on October 24, 2019, ASHRAE published ASHRAE 90.1–2019. In none of these
On July 29, 2019, DOE published a request for information (“RFI”) to solicit information and data from interested parties to consider amendments to the DOE energy conservation standards for ECUACs and WCUACs. 84 FR 36480 (“July 2019 ECS RFI”).
On September 15, 2020 DOE published a notice of proposed determination (“NOPD”) with the tentative determination that energy conservation standards for ECUACs and WCUACs do not need to be amended (“September 2020 NOPD”). 85 FR 57149. The comment period for this notice closed on November 30, 2020. On October 1, 2020, DOE held a public webinar
DOE received several comments from interested parties in response to the publication of the September 2020 NOPD. Table II.2 lists the commenters, their abbreviated names used throughout this final determination, and organization type. Discussion of the relevant comments provided by these organizations and DOE's responses are provided in the appropriate sections of this document.
A parenthetical reference at the end of a comment, quotation or paraphrase provides the location of the item in the public record.
DOE developed the conclusions in this notice after considering oral and written comments, data, and information from interested parties that represent a variety of interests. This section addresses the analyses DOE performed for this final determination regarding ECUACs and WCUACs. Separate subsections address each component of DOE's analyses and responses to relevant comments received regarding the September 2020 NOPD.
In response to the September 2020 NOPD, DOE received several general comments. CA IOUs supported DOE's initial determination to maintain the current standards, stating that the market for this equipment is extremely small. (CA IOUs, No. 13 at p. 2) UCA stated that if DOE is correct in its assumed decline of shipments, then there is no need for an increase in efficiency at this time. (UCA, No. 11 at p. 1)
As discussed below, DOE has determined that it lacks clear and convincing evidence that amended standards for ECUACs and WCUACs would result in significant additional energy savings and be technologically feasible and economically justified.
DOE received comments from UCA and CA IOUs regarding the test procedures for ECUACs and WCUACs. (UCA, No. 11 at p. 1; CA IOUs, No. 13 at p. 2) UCA stated that several third party test facilities are limited in the physical size and capacity limits they can test; therefore, they stated that certain UCA models cannot be tested at these facilities. (UCA, No. 11 at p. 1) CA IOUs encouraged DOE to expedite work on an updated test standard for all CUACs. (CA IOUs, No. 13 at p. 2) Specifically, CA IOUs commented that the Appliance Standards and Rulemaking Federal Advisory Committee (“ASRAC”), Commercial Package Air Conditioners and Commercial Warm Air Furnaces Working Group unanimously agreed that a new test procedure for CUACs, which should include a more representative evaluation of indoor fan power consumption, should be completed no later than January 1, 2019.
The September 2020 NOPD sought comment on DOE's determination of whether the energy conservation standards for ECUACs and WCUACs should be amended. Consideration of amendments to the test procedures are not within the scope of this determination. DOE will consider comments received regarding ECUAC and WCUAC test procedures in the ongoing evaluation of the CUAC test procedure.
The current energy efficiency descriptor for the ECUAC and WCUAC Federal standards is EER. 10 CFR 431.97. ASHRAE 90.1 has specified both EER and integrated energy efficiency ratio (“IEER”) minimum efficiency levels since 2010.
The EER metric represents the efficiency of the equipment operating at full load. The IEER metric factors in the efficiency of operating at part loads of 75 percent, 50 percent, and 25 percent of capacity as well as the efficiency at full load by weighting the full- and part-load efficiencies based on the average amount of time operating at each load point. Additionally, IEER incorporates reduced condenser temperatures (
The following equation shows the weighting factors for each testing condition.
The intent of this weighted average across a range of condenser temperatures is to produce an IEER rating that is more representative of outdoor conditions that air conditioners face for much of the year, rather than just the peak temperature experienced in most climates for only a small minority of operating hours.
In the September 2020 NOPD, DOE proposed to maintain standards for ECUACs and WCUACs in terms of EER because the current IEER metric may not be representative for ECUACs and WCUACs and compliance with IEER would impose additional testing and certification burden on a small market. 85 FR 57149, 57161. DOE initially determined that for ECUACs, the weighting factors for IEER may not be representative of typical applications.
ECUACs may be disproportionately marketed and sold in relatively hot and dry climates where there is a larger efficiency benefit to using evaporative condenser cooling. 85 FR 57149, 57160. The IEER equation assigns a weighting factor of just 2 percent for the full-load test point, so almost all of the IEER rating for ECUACs would reflect performance at outdoor air temperatures which is cooler than what would typically be experienced in the hot and dry climates where this equipment is installed. For ECUACs with cooling capacity less than 65,000 Btu/h DOE's preliminary analysis suggested that these units are primarily marketed for residential applications, whereas the IEER metric was developed for commercial applications by analyzing air conditioner energy use in commercial buildings.
Additionally, IEER requires at least four tests whereas EER requires a single test. Examining the models listed in the CCMS database, DOE found that many models did not have any online product literature demonstrating that they are rated with IEER, suggesting that many WCUAC and ECUAC models would need to be retested in order to comply with Federal IEER standards. 85 FR 57149, 57161.
In response to the September 2020 NOPD, DOE received several comments in support of its proposal to maintain standards in terms of the EER metric. UCA supported DOE's proposal to maintain the EER metric for WCUACs, stating that they disagreed with using IEER for certain WCUACs installed indoors within mechanical rooms because these units typically see constant water temperatures year-round. (UCA, No. 11 at p. 1) CA IOUs supported maintaining EER and not adopting IEER for ECUACs until the test procedure has been updated and DOE has evaluated the appropriate condenser entering air dry-bulb and wet-bulb temperatures for the climates in which ECUACs are typically installed. (CA IOUs, No. 13 at p. 2)
Regarding WCUACs, CA IOUs stated that if DOE were to adopt IEER, DOE should complete the test procedure rulemaking first and consider aligning the temperature test points and weighting factors with those of water-cooled variable refrigerant flow (“VRF”) equipment. (CA IOUs, No. 13 at p. 2; Public Webinar Transcript,
For the reasons provided previously and presented in the September 2020 NOPD, DOE is maintaining federal standards for ECUACs and WCUACs in terms of EER.
DOE's analysis in support of the final determination is based on an evaluation of ECUACs and WCUACs in terms of EER.
DOE develops information in the market analysis that provides an overall picture of the market for the equipment concerned. For this final determination, DOE conducted a review of the current market for ECUACs and WCUACs, including equipment literature, the AHRI Directory of Certified Product Performance (“AHRI Directory”),
DOE uses projections of annual product shipments to calculate the national impacts of potential amended energy conservation standards on energy use.
The analysis conducted for the September 2020 NOPD was based on the same model specification used for the May 2012 final rule and incorporated additional shipments data provided by AHRI in response to the July 2019 ECS RFI. 85 FR 57149, 57155–57156. Based on the shipments data, the DOE September 2020 NOPD analysis indicated declining future shipments for WCUACs and ECUACs with cooling capacity less than 65,000 Btu/h.
Table III.2 presents the historical shipments for WCUACs from the May 2012 final rule (1984–2009) along with historical shipments in the following years as provided by AHRI (2010–2018). As shown in Table III.2 for the small and large WCUACs, shipments starting in 2009 are lower than in prior years. The very large WCUAC shipments fell in the years immediately following 2008, and while the shipments have rebounded, they did not rebound to the highest shipment levels seen previously.
DOE developed two shipment projections for the September 2020 NOPD analysis; one based on historical trends and one that held shipments constant at the 2018 shipment level (referred to as “2019 trend” and “2019 constant”, respectively). 85 FR 57149, 57155–57156. The 2019 trend and 2019 constant projections are compared to projections from the May 2012 final rule that were based on the historical trends and fixed at the level of the 2009 shipments (referred to as “2012 trend” and “2012 constant”, respectively). This comparison is shown in Table III.3 of this document.
DOE was unable to identify shipments data for the ECUAC equipment classes and none were provided by the stakeholders. For the September 2020 NOPD analysis, shipment projections were developed by scaling the WCUAC shipment projections using a ratio of unique model counts for each equipment class. 85 FR 57149, 57155. For the small (cooling capacity less than 65,000 Btu/h) ECUAC class of products, the shipment projection was further adjusted by a factor of 0.5 to better reflect the approximate size of the market in the mid-2000s.
WCUACs are typically sold as part of a large project (
In the May 2012 final rule, DOE did not analyze small ECUACs and WCUACs with cooling capacity less than 65,000 Btu/h. 77 FR 28927, 28934–28937. For the July 2019 ECS RFI, DOE identified a single manufacturer of ECUACs in this capacity range, and the models offered are single-phase equipment and appear to be predominantly marketed for residential applications in regions of the United States with hot and dry climates, suggesting that there are few if any shipments in other regions of the United States. 84 FR 36480, 36485. DOE identified only two distinct product lines of WCUACs with cooling capacity less than 65,000 Btu/h, and DOE's examination of manufacturer literature for these WCUACs suggested that these models do not comprise a significant share of the market for air conditioners in residential or commercial applications.
The projected trends from the May 2012 final rule and those based on the updated data both generally show declines in shipments for small (≥65,000 and <135,000 Btu/h), large and very large WCUACs, and very large ECUACs. The shipment levels under the 2019 constant projections are lower than the 2012 constant projections for small (≥65,000 and <135,000 Btu/h) and large WCUACs and very large ECUACs. The 2019 constant projections for very large WCUACs are higher than the 2012 constant projections (but lower than the 2012 trend projections). The 2019 regression projections for very large WCUACs and ECUACs show a more stable level of shipments over the analysis period than the 2019 trend models, but are lower than the 2012 trend projection.
Given that DOE did not analyze ECUACs and WCUACs with cooling capacity less than 65,000 Btu/h for the May 2012 final rule, no comparisons to the current projections are possible. The current trended shipments projections for the small (cooling capacity less than 65,000 Btu/h) equipment classes reach 10 or fewer shipments by 2045.
In response to the September 2020 NOPD, UCA stated that the historical shipments data presented by DOE is not complete and asserted that the shipments data does not capture dozens of manufacturers that do not belong to
In the July 2019 ECS RFI, DOE requested data on shipments, and in response to the RFI, DOE received shipments data from AHRI. In the September 2020 NOPD, DOE presented the shipments information received to that point. In addition, DOE requested comments and data concerning the tentative determination and the underlying data and analyses. The previously discussed number of shipments provided by UCA (40 units) only applies for a single manufacturer for a single equipment class of WCUAC (<65,000 Btu/h) equipment for a single year. Because this was a single data point, DOE lacked sufficient context to incorporate it into the shipment analysis (
UCA also disagreed with shipment trends showing a decline in WCUACs over the next 20-plus years, as it stated that there are thousands of WCUACs that will be replaced over the next decade in the very large WCUAC class. (UCA, No. 11 at p. 1) UCA also commented that its sales for its main equipment line has gone down substantially, and that the equipment capacities it now offers are more limited. (UCA, No. 11–1
Trane commented that there was a major drop in unitary air conditioner shipments that also affected WCUACs and ECUACs during the great recession of 2008(?), so looking forward 15–20 years, the market should also reflect that drop because there will not be units to replace. (Public Webinar Transcript, No. 10 at p. 15) Daikin commented that the need for office space likely will be declining for the foreseeable future stating that it was informed by one office building client that the client will only need about 70 percent of its current square footage going forward. (Public Webinar Transcript, No. 10 at p. 11)
As stated, DOE did not receive additional shipments data in response to the September 2020 NOPD. As such, DOE relied on the shipments data presented in the September 2020 NOPD for this final determination. Based on the existing shipments data, DOE developed a series of shipment projections to reflect uncertainty in the future of ECUAC and WCUAC shipments. As presented in the September 2020 NOPD, DOE developed three shipment projections (“2019 trend,” “2019 constant,” and “2019 regression”). DOE continued to rely on the 2019 trend, 2019 constant, and 2019 regression projections presented in September 2020 NOPD for this final determination. Additionally, DOE performed a sensitivity case to reflect a potential underreporting of ECUAC and WCUAC shipments. DOE developed a sensitivity analysis by multiplying the three shipment projections by 10 for all equipment classes to examine an upper bound estimate for potentially unreported shipments. The results of the sensitivity analysis are presented in section III.C.3 of this document.
Prior to receipt of updated shipments from AHRI in response to the July 2019 ECS RFI, DOE conducted a review of the market for WCUACs and ECUACs based on models included in the DOE CCMS database.
For the September 2020 NOPD, DOE examined the efficiency ratings of ECUACs and WCUACs currently on the market and presented efficiency distributions to reflect the current market. 85 FR 57149, 57157–57159. Table III.4 presents the summary of statistics by equipment category and capacity range of equipment for unique models
DOE used these efficiency distributions and the previously described shipment projections to develop estimated energy savings and percent of no-new-standards energy consumption for 30 years of shipments (2020–2049).
Energy savings were estimated based on the forecasted shipments labeled 2019 trend, 2019 constant, and 2019 regression. For the savings estimates labeled 2019 regression, as noted in section III.C.1 of this final determination, a regression projection was only developed for the very large equipment class.
As mentioned in section II.B.2 of this final determination, the cumulative site energy savings are calculated using the max-tech level, which is the highest value of efficiency in DOE's CCMS Database within each capacity range of ECUACs and WCUACs (
For the September 2020 NOPD, DOE did not incorporate changing trends in shipments by efficiency over time in the no-new-standards case. No comments were received on efficiency trends and DOE retained this assumption in the energy savings estimates, which vary by shipment scenario and equipment class, presented in Table III.5 of this final determination.
Selecting the minimum and maximum estimated savings scenario for each equipment class resulted in a range of total estimated site energy savings for the WCUAC classes of between 0.0030 quads (8.5 percent of estimated site energy use) and 0.0046 quads (8.6 percent of estimated site energy use), and for the ECUAC classes of 0.00006 quads (6.2 percent of estimated site energy use) and 0.00011 quads (6.0 percent of estimated site energy use) during the analysis period. For both equipment categories, the resulting estimated savings ranged between 0.0031 quads (8.5 percent of estimated site energy consumption) and 0.0047 quads (8.6 percent of estimated site energy consumption) during the analysis period depending on the combination of shipment projections analyzed. Because DOE received no comments resulting in changes to inputs or the analysis, the estimate savings presented in Table III.5 are the same as those presented in the September 2020 NOPD.
As noted in section III.C.1 of this document, in response to a UCA comment regarding the completeness of shipment data, DOE conducted a sensitivity analysis by multiplying annual shipments in the three shipment projections by 10 and calculating the resulting estimated energy savings using the higher shipment projections. This sensitivity resulted in estimated total site energy savings for the WCUAC classes of between 0.0303 quads (8.5 percent of estimated site energy use of the evaluated equipment) and 0.0456 quads (8.6 percent of estimated site energy use of the evaluated equipment), and for the ECUAC classes of 0.0006 quads (6.2 percent of estimated site energy use of the evaluated equipment) and 0.0011 quads (6.0 percent of estimated site energy use of the evaluated equipment) during the analysis period. For both equipment categories, the resulting estimated savings ranged between 0.0308 quads (8.5 percent of estimated site energy use of the evaluated equipment) and 0.0467 quads (8.6 percent of estimated site energy use of the evaluated equipment) during the analysis period.
As required by EPCA, this final determination analyzes whether amended standards for ECUACs and WCUACs would result in significant conservation of energy, be technologically feasible and economically justified. 42 U.S.C. 6313(a)(6)(A)(ii)(II). DOE has determined that the energy conservation standards for WCUACs and ECUACs do not need to be amended, having determined that it lacks “clear and convincing” evidence that amended standards would result in significant additional conservation of energy. As previously discussed, EPCA specifies that for any commercial and industrial equipment addressed under 42 U.S.C. 6313(a)(6)(A)(i), including WCUACs and ECUACs, DOE may prescribe an energy conservation standard more stringent than the level for such equipment in ASHRAE Standard 90.1 only if “clear and convincing evidence” shows that a more stringent standard would result in significant additional conservation of energy and is technologically feasible and economically justified. (42 U.S.C. 6313(a)(6)(C)(i); 42 U.S.C. 6313(a)(6)(A)(ii)(II))
IPI objected to DOE's reliance on the significance of energy threshold established in the Process Rule. (IPI, No, 12 at p. 1) IPI reiterated its comments regarding the significance of energy threshold it previously submitted to the rulemaking to update the Process Rule. (
DOE disagrees with IPI's characterization of the statutory requirements applicable in the present case. EPCA specifically stipulates that the Secretary may not adopt a uniform national standard more stringent than the amended ASHRAE Standard 90.1 unless such standard would result in significant additional conservation of energy and is technologically feasible and economically justified. (42 U.S.C. 6313(a)(6)(A)(ii)(II)). A determination of whether energy savings would be significant is distinct from consideration of potential consumer cost impacts or environmental impacts, which are separate considerations in determining whether an amended standard is economically justified. (
An analysis of shipments data, a review of the CCMS database and the AHRI Directory, and comments received indicate that WCUACs and ECUACs continue to be a minor portion of total commercial air-cooled shipments with total combined shipments of less than 1,300 units in 2018. The shipments of very large WCUACs may be cyclical, linked to investment in commercial buildings, but the shipment projections also suggest that shipments may be continuing to decline.
DOE estimates that amended standards for ECUACs at the respective “max-tech” levels would result in additional site energy savings of no more than 0.0001 quads during the analysis period. DOE has determined the energy savings potential for ECUACs is
For WCUACs, DOE estimated the additional energy savings based on the max- tech levels for small and large WCUACs, which were determined by identifying the highest efficiency ratings in the DOE CCMS Database. For very large WCUACs DOE determined that there is substantial doubt as to the appropriateness of using the highest efficiency reported in the DOE CCMS Database as the max-tech level. As discussed, there is a substantial question of whether the combination of technologies used to achieve the highest reported level for very large WCUACs is practicable for basic models across the capacity range of that equipment class. As such, DOE has determined that an energy savings calculation that would rely on the highest reported efficiency for very large WCUACs would not meet the “clear and convincing evidence” threshold required by EPCA. Instead, DOE analyzed the next most efficient level reported in the DOE CCMS
Using this next highest efficiency level for very large WCUACs and the max-tech efficiency levels for the small and large classes of WCUACs, DOE calculated that amended standards would result in additional site energy savings of no more than 0.0046 quads for all WCUAC classes during the analysis period. DOE has determined the energy savings potential for WCUACs is
This final determination has been determined to be not significant for purposes of Executive Order (“E.O.”) 12866, Regulatory Planning and Review, 58 FR 51735 (Oct. 4, 1993). As a result, the Office of Management and Budget (“OMB”) did not review this final determination.
The Regulatory Flexibility Act (5 U.S.C. 601
In response to the NOPD, UCA provided a number of general comments regarding the potential impacts of efficiency regulations on equipment and small businesses. UCA commented that small businesses are often not members of trade associations and do not have staff reading the
DOE reviewed this final determination pursuant to the Regulatory Flexibility Act and the policies and procedures published on February 19, 2003. As stated, this final determination is not amending standards for ECUACs and WCUACs. Further, this final determination does not amend the certification and reporting requirements. Therefore, DOE certifies that this final determination has no significant economic impact on a substantial number of small entities. Accordingly, DOE has not prepared a final regulatory flexibility analysis (“FRFA”) for this final determination. DOE will transmit this certification and supporting statement of factual basis to the Chief Counsel for Advocacy of the Small Business Administration for review under 5 U.S.C. 605(b).
Manufacturers of ECUACs and WCUACs must certify to DOE that their equipment complies with any applicable energy conservation standards. In certifying compliance, manufacturers must test their equipment according to the DOE test procedures for ECUACs and WCUACs, including any amendments adopted for those test procedures. DOE has established regulations for the certification and recordkeeping requirements for all covered consumer products and commercial equipment, including ECUACs and WCUACs. 76 FR 12422 (March 7, 2011); 80 FR 5099 (Jan. 30, 2015). The collection-of-information requirement for the certification and recordkeeping is subject to review and approval by OMB under the Paperwork Reduction Act (“PRA”). This requirement has been approved by OMB under OMB control number 1910–1400. Public reporting burden for the certification is estimated to average 35 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.
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.
Pursuant to the National Environmental Policy Act of 1969 (“NEPA”), DOE has analyzed this final determination in accordance with NEPA and DOE's NEPA implementing regulations (10 CFR part 1021). DOE has determined that this rule qualifies for categorical exclusion A4 because it is an interpretation or ruling in regards to an existing regulation and otherwise meets the requirements for application of a categorical exclusion. See 10 CFR 1021.410. Therefore, DOE has determined that promulgation of this rule is not a major Federal action significantly affecting the quality of the human environment within the meaning of NEPA, and does not require an environmental assessment or an environmental impact statement.
Executive Order 13132, “Federalism,” 64 FR 43255 (Aug. 10, 1999), imposes certain requirements on Federal agencies formulating and implementing policies or regulations that preempt State law or that have Federalism implications. 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 it will follow in the development of such regulations. 65 FR 13735. As this final determination does not amend the standards for ECUACs and WCUACs, there is no impact on the policymaking discretion of the States. Therefore, no action is required by Executive Order 13132.
With respect to the review of existing regulations and the promulgation of new regulations, section 3(a) of Executive Order 12988, “Civil Justice Reform,” imposes on Federal agencies the general duty to adhere to the following requirements: (1) Eliminate drafting errors and ambiguity, (2) write 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. 61 FR 4729 (Feb. 7, 1996). Regarding the review required by section 3(a), section 3(b) of Executive Order 12988 specifically requires that Executive agencies make every reasonable effort to ensure that the regulation: (1) Clearly specifies the preemptive effect, if any, (2) clearly specifies any effect on existing Federal law or regulation, (3) provides a clear legal standard for affected conduct while promoting simplification and burden reduction, (4) specifies the retroactive effect, if any, (5) adequately defines key terms, and (6) addresses 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 section 3(a) and section 3(b) to determine whether they are met or 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 final determination meets the relevant standards of Executive Order 12988.
Title II of the Unfunded Mandates Reform Act of 1995 (“UMRA”) requires each Federal agency to assess the effects of Federal regulatory actions on State, local, and Tribal governments and the private sector. Public Law 104–4, sec. 201 (codified at 2 U.S.C. 1531). 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 a written statement that estimates the resulting costs, benefits, and other effects on the national economy. (2 U.S.C. 1532(a), (b)) The 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 them. On March 18, 1997, DOE published a statement of policy on its process for intergovernmental consultation under UMRA. 62 FR 12820. DOE's policy statement is also available at
This final determination does not contain a Federal intergovernmental mandate, nor is it expected to require expenditure of $100 million or more in one year by State, local, and Tribal governments, in the aggregate, or by the private sector. As a result, the analytical requirements of UMRA do not apply.
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. This final determination 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.
Pursuant to Executive Order 12630, “Governmental Actions and Interference with Constitutionally Protected Property Rights,” 53 FR 8859 (March 15, 1988), DOE has determined that this final determination would not result in any takings that might require compensation under the Fifth Amendment to the U.S. Constitution.
Section 515 of the Treasury and General Government Appropriations Act, 2001 (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). Pursuant to OMB Memorandum M–19–15, Improving Implementation of the Information Quality Act (April 24, 2019), DOE published updated guidelines which are available at
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 the Office of Information and Regulatory Affairs (“OIRA”) at OMB, a Statement of Energy Effects for any 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 significant energy action, the agency must give a detailed statement of any adverse effects on energy supply, distribution, or use should the proposal be implemented, and of reasonable alternatives to the action and their expected benefits on energy supply, distribution, and use.
Because this final determination does not amend the current standards for ECUACs and WCUACs, it is not a significant energy action, nor has it been designated as such by the Administrator at OIRA. Accordingly, DOE has not prepared a Statement of Energy Effects.
On December 16, 2004, OMB, in consultation with the Office of Science and Technology Policy (“OSTP”), issued its Final Information Quality Bulletin for Peer Review (“the Bulletin”). 70 FR 2664 (Jan. 14, 2005). The Bulletin establishes that certain scientific information shall be peer reviewed by qualified specialists before it is disseminated by the Federal Government, including influential scientific information related to agency regulatory actions. The purpose of the bulletin is to enhance the quality and credibility of the Government's scientific information. Under the Bulletin, the energy conservation standards rulemaking analyses are “influential scientific information,” which the Bulletin defines as “scientific information the agency reasonably can
In response to OMB's Bulletin, DOE conducted formal peer reviews of the energy conservation standards development process and the analyses that are typically used and has prepared a report describing that peer review.
The Secretary of Energy has approved publication of this final determination.
