DOE Issues a Notice of Proposed Rulemaking, Public Meeting and Request for Comment Pertaining to Standards for Air-Cooled Three-Phase, Small Commercial Package Air Conditioning and Heating Equipment and Air-Cooled, Three-Phase, Variable Refrigerant Flow Air Conditioners and Heat Pumps

The U.S. Department of Energy (DOE) has issued a pre-publication Federal Register notice pertaining to energy conservation standards for air-cooled, three-phase, small commercial air conditioners and heat pumps and air-cooled, three-phase, variable refrigerant flow air conditioners and heat pumps. The Energy Policy and Conservation Act, as amended (EPCA), prescribes standards for small, large, and very large commercial package air conditioning and heating equipment, of which air cooled, three-phase, small commercial air conditioners and heat pumps with a cooling capacity of less than 65,000 Btu/h and air-cooled, three-phase, variable refrigerant flow air conditioners and heat pumps with a cooling capacity of less than 65,000 Btu/h are categories. 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. For the three-phase equipment that is the subject of this notice of proposed rulemaking (NOPR), DOE is proposing amended standards that rely on new efficiency metrics and align with amended efficiency levels in the industry standard. DOE has preliminarily determined that it lacks clear and convincing evidence required by the statute to adopt standards more stringent than the levels specified in the industry standard.
