Description:  TITLE: Energy Conservation Program: Energy Conservation Standards for Computer 
Room Air Conditioners  
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of Energy  
ACTION: Final rule  
SUMMARY: The Energy Policy and Conservation Act , as amended  (EPCA), prescribes energy 
conservation standards for various consumer products and certain commercial and industrial

  equipment, including small , large, and very large commercial package air conditioning and heating 
equipment, of which computer room air conditioners (CRACs)  are a category. EPCA r equires the U.S. 
Department of Energy (DOE or the Department) to consider the need for amended standards each 
time American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) Standard 
90.1 is amended with respect to the standard leve ls or design requirements applicable to that 
equipment, or periodically under a six -year-lookback review provision. In this final rule, DOE is 
adopting amended energy conservation standards for CRACs that rely on a new efficiency metric 
and are equivalent to those levels specified in ASHRAE Standard 90.1 -2019. DOE has determined 
that it lacks the clear and convincing evidence required by the statute to adopt standards more 
stringent than the levels specified in the industry standard.  
DATES: The effective da te of this rule is 1 August 2023. Compliance with the amended standards 
established for computer room air conditioners in this final rule is required on and after 28 May 
2024.
