DOE Proposes Supplemental Rule on Standards for Certain AC & Heat Pump Units

On January 17, 2012, the Energy Department issued a proposed rule on energy conservation standards for several classes of commercial heating, air-conditioning, and water-heating equipment. The DOE is now issuing a supplement to that proposed rule that would (i) modify the initially proposed definition of “computer room air conditioner”, (ii) clarify the proposed test procedure provisions for commercial package air-conditioning and heating equipment and variable refrigerant flow systems, and (iii) clarify the application of the DOE test procedures and harmonize DOE testing with the testing performed by industry. The DOE is seeking comments on this supplemental rule by April 2, 2012.
