Amended Energy Conservation Standards Proposed for Heating/Air Conditioning Equipment
The Department of Energy’s Office of Energy Efficiency and Renewable Energy is proposing to amend its energy conservation standards for several classes of commercial heating, air-conditioning and water-heating equipment. Based on its analysis of the energy savings potential of amended energy conservation standards and the lack of clear and convincing evidence to support more stringent standards, DOE is proposing to adopt the amended standards in ASHRAE Standard 90.1 for small, large and very large water-cooled and evaporatively-cooled commercial package air conditioners, variable refrigerant flow water-source heat pumps less than 17,000 Btu/h, VRF watersource heat pumps at or greater than 135,000 Btu/h, and computer room air conditioners. DOE is also proposing updates to the current federal test procedures to incorporate by reference the most current versions of specified industry test procedures for small commercial package air conditioning and heating equipment, large and very large commercial package air conditioning and heating equipment, commercial warm-air furnaces and commercial water heaters. Furthermore, DOE is proposing to adopt standards AHRI 1230 for newly-created classes of VRF air conditioners and heat pumps, ASHRAE 127 for computer room air conditioners, and AHRI 390 for single package vertical air conditioners and single package vertical heat pumps.
DOE will hold a public meeting Feb. 14 to receive comments on its proposal and related issues. This meeting will also be broadcast as a webinar. Final comments on this proposal are due no later than April 3.
