Energy Conservation Program: Energy Conservation Standards for Evaporatively-Cooled Commercial Package Air Conditioners and Water-Cooled Commercial Package Air Conditioners

The Energy Policy and Conservation Act ("EPCA"), as amended, prescribes energy conservation standards for various consumer products and certain commercial and industrial equipment, including evaporatively-cooled commercial package air conditioners and water- cooled commercial package air conditioners (referred to as evaporatively-cooled commercial unitary air conditioners ("ECUACs") and water-cooled commercial unitary air conditioners ("WCUACs") in this document). EPCA also requires the U.S. Department of Energy ("DOE") to periodically determine whether more stringent, amended standards would result in significant additional conservation of energy, be technologically feasible, and be economically justified. In this final determination, DOE has determined that more stringent standards for small (cooling capacity less than 135,000 Btu/h), large (cooling capacity greater than or equal to 135,000 and less than 240,000 Btu/h), and very large (cooling capacity greater than or equal to 240,000 and less than 760,000 Btu/h) ECUACs and WCUACs would not result in significant additional conservation of energy, and thus has determined that the standards for ECUACs and WCUACs do not need to be amended.
