The U.S. Department of Energy (DOE) has published a Federal Register final rule pertaining to energy conservation standards for computer room air conditioners (CRACs). The Energy Policy and Conservation Act (EPCA), prescribes 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 requires DOE 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 levels or design requirements applicable to that equipment, or periodically under a six-year-lookback review provision. In this final rule, DOE is adopting amended 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.
- The effective date of this rule is August 1, 2023.
- Compliance with the amended standards established for computer room air conditioners in this final rule is required on and after May 28, 2024.
