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.

Energy Conservation Standard Rulemaking 

z 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: 

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 minimum efficiency standards. (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 

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

 EE-RM-STD-01-375 COMMENT 24
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.
