DOE Publishes a Notice of Proposed Rulemaking, Public Meeting and Request for Comment Pertaining to Standards for Computer Room Air Conditioners

The U.S. Department of Energy (DOE) has published a Federal Register notice of proposed rulemaking and request for comment 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 CRACs are a category. EPCA requires DOE to consider the need for amended standards each time the relevant industry standard 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 document, DOE is proposing amended standards for CRACs that rely on a new efficiency metric and are equivalent to those levels specified in the industry standard. DOE has preliminarily 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. This document also announces a public meeting webinar to receive comment on these proposed standards and associated analyses and results.

  • DOE will accept comments, data, and information regarding this NOPR until May 6, 2022.
