Pursuant to the 7-year look-back provision in Energy Policy and Conservation Act (EPCA) (42 U.S.C. 6314(a)(1)(A)), the U.S. Department of Energy (DOE) is evaluating the test procedures for commercial refrigeration equipment (CRE) to determine whether amended test procedures for CRE would more accurately or fully comply with the requirements in EPCA that test procedures: 1) be reasonably designed to produce test results which reflect energy use during a representative average use cycle; and 2) not be unduly burdensome to conduct. DOE proposes to amend the test procedures for commercial refrigerators, refrigerator-freezers, and freezers to reference the latest versions of the applicable industry standards. DOE also proposes to establish definitions and test procedures for new equipment categories, adopt test procedures consistent with recently published waivers and interim waivers, establish product-specific enforcement provisions, allow for volume determinations based on computer aided designs, specify a sampling plan for volume and total display area, and adopt additional clarifying amendments.
