## Commercial Unitary Air Conditioners and Heat Pumps The U.S. Department of Energy (DOE or the Department) is required by the Energy Policy and Conservation Act and its amendments to consider national energy conservation standards for certain commercial unitary air conditioners and heat pumps. The Department has gathered and analyzed data and information for the Advance Notice of Proposed Rulemaking (ANOPR) and its Technical Support Document (TSD), as part of the standards rulemaking process. To fulfill DOE's commitment to the July 1996 Process Rule (61 FR 36974) — to make information available to the public as soon as possible — the ANOPR document, the TSD, and the analysis tools for the ANOPR analysis are available below. Some of the following documents are available as Adobe Acrobat PDFs. Download Acrobat Reader

### Energy Conservation Standard Rulemaking

● Notice of Availability: The Department of Energy announces the availability of the "Joint Stakeholders Comments on Standards for Commercial Package Air Conditioners and Heat Pumps" and an opportunity for public comment. Federal Register, February 15, 2005, ( PDF 59 KB ) The Department received comments from a group of nineteen significant stakeholders in response to the Advance Notice of Proposed Rulemaking for Commercial Unitary Air Conditioners and Heat Pumps. 69 FR 45460 (July 29, 2004). In summary, the Joint Stakeholders recommend minimum energy efficiency ratios (EERs) and coefficients of performance (COPs) for certain commercial unitary air conditioners and heat pumps, both split and package systems, respectively, as follows:
Air-Cooled Products Efficiency Standards >65,000 - <135,000 Btu/h 11.2/11.0 EER for Air Conditioners 11.0/10.8 EER for Heat Pumps 3.3 COP @ 47oF for Heat Pumps >135,000 - <240,000 Btu/h 11.0/10.8 EER for Air Conditioners 10.6/10.4 EER for Heat Pumps 3.2 COP @ 47oF for Heat Pumps NOTE: Where two EERs are listed, the first refers to systems with electric resistance heat or no heating, and the second refers to systems with all other heating-system types that are integrated into the unitary equipment. Further, the Joint Stakeholders have asked DOE to adopt January 1, 2010, as the effective date for compliance with the recommended

( PDF 251 KB ) To help DOE determine the appropriate next step in this rulemaking, DOE invites interested members of the public to submit any comments they may have on the Joint Stakeholders Comments, including the recommendation for expediting proceedings by adopting these recommended efficiency standards through a direct final rule.
Comments must be submitted to one of the addresses listed in the ADDRESSES section of the above Notice of Availability. The Department will accept written comments, data, and information regarding the Joint Stakeholders Comments until April 1, 2005
