Energy Conservation Program for Certain Industrial Equipment: Energy Conservation Standards and Test Procedures for Commercial Heating, Air-Conditioning, and Water-Heating Equipment

The U.S. Department of Energy (DOE) is amending its energy conservation standards for small three-phase commercial air-cooled air conditioners (single package only) and heat pumps (single package and split system) less than 65,000 Btu/h; water-source heat pumps; and commercial oil-fired storage water heaters. Pursuant to the Energy Policy and Conservation Act of 1975 (EPCA), as amended, DOE must assess whether the uniform national standards for these covered equipment need to be updated each time the corresponding industry standard--the American National Standards Institute (ANSI)/American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE)/ Illuminating Engineering Society of North America (IESNA) Standard 90.1 (ASHRAE Standard 90.1)--is amended, which most recently occurred on October 9, 2013. Under EPCA, DOE may only adopt more stringent standards if there is clear and convincing evidence showing that more stringent amended standards would be technologically feasible and economically justified, and would save a significant additional amount of energy. The levels DOE is adopting are the same as the efficiency levels specified in ASHRAE Standard 90.1-2013. DOE has determined that the ASHRAE Standard 90.1-2013 efficiency levels for the equipment types listed above are more stringent than existing Federal energy conservation standards and will result in economic and energy savings compared existing energy conservation standards. Furthermore, DOE has concluded that clear and convincing evidence does not exist that would justify more-stringent standard levels than the efficiency levels in ASHRAE Standard 90.1-2013 for any of the equipment classes. DOE has also determined that the standards for small three-phase commercial air-cooled air conditioners (split system) do not need to be amended. DOE is also updating the current Federal test procedure for commercial warm-air furnaces to incorporate by reference the most current version of the American
