Energy Conservation Program: Alternative Efficiency Determination Methods, Basic Model Definition, and Compliance for Commercial HVAC, Refrigeration, and WH Equipment

Краткое содержание

The U.S. Department of Energy (DOE) is proposing to revise and expand its existing regulations governing the use of particular methods as alternatives to testing for the purposes of certifying compliance with the applicable energy conservation standards and the reporting of related ratings for commercial and industrial equipment covered by EPCA. The proposals contained in this supplemental notice arose from a negotiated rulemaking effort on issues regarding certification of commercial heating, ventilating, air-conditioning (HVAC), water heating (WH), and refrigeration equipment. In addition, DOE is proposing to amend the compliance dates for the initial certification of commercial HVAC, WH, and refrigeration equipment.
