The Energy Policy and Conservation Act, as amended, requires DOE to evaluate its test procedure for each class of covered equipment once every seven years (42 U.S.C. 6314(a)(1)). This equipment includes small air-cooled commercial package air conditioning and heating equipment which includes three-phase commercial air-cooled air conditioners and heat pumps less than 65,000 Btu/h (42 U.S.C. 6311(1)(B) to (D)). If DOE determines that an amended test procedure would more accurately or fully comply with the requirement to be reasonably designed to produce test results that reflect the energy efficiency, energy use, and operating costs during a representative average use cycle, and to not be unduly burdensome to conduct, DOE must prescribe amended test procedures (following publication of a proposal and opportunity for comment). Otherwise, DOE must publish a notice in the Federal Register regarding its determination not to amend the test procedures.
