INFORMATIVE APPENDIX F U.S. DEPARTMENT OF ENERGY MINIMUM ENERGY EFFICIENCY REQUIREMENTS, TEST PROCEDURES, AND DEFINITIONS
In the United States, the U.S. Department of Energy (U.S. DOE) establishes efficiency standards for products that it defines as “residential covered products.” Since these products are used in buildings covered by this standard, U.S. DOE efficiency requirements are shown here for convenience. All U.S. DOE efficiency requirements for residential products are found in the U.S. Code of Federal Regulations, 10 CFR 430.32.
DOE also establishes definitions and test procedures for covered products. These are found in 10 CFR 430.2 and 10 CFR 430.23, respectively.
F1. U.S. DOE MINIMUM ENERGY EFFICIENCY REQUIREMENTS FOR SINGLE-PHASE AIR CONDITIONERS AND HEAT PUMPS
These standards became effective on January 1, 2015. In the United States, some of the standards are regional in nature. The U.S. has been divided into 3 regions: (a) the north, comprising states with a population weighted heating degree days (HDD) equal to or greater than 5000; (b) the southeast, comprising states with a population weighted HDD less than 5000; and (c) the southwest, comprising Arizona, California, Nevada, and New Mexico. The regions are shown in Figure F-1.
The U.S. federal minimum energy efficiency standards for single-phase air conditioners and heat pumps are shown in Table F-1. The standards apply to residential single-phase air conditioners and heat pumps that are rated at less than 65,000 Btu/h of cooling capacity.
F2. U.S. DOE MINIMUM ENERGY EFFICIENCY REQUIREMENTS FOR WATER HEATERS AND POOL HEATERS
These standards for Uniform Energy Factor became effective on December 29, 2017, and apply to products manufactured on or after that date and the thermal efficiency requirements for gas fired pool heaters manufactured on or after April 16, 2013 (Table F-2).
F3. U.S. DOE TEST PROCEDURE AND DEFINITIONS FOR CEILING FANS
U.S. DOE definitions for ceiling fans are found in 10 CFR 430.2 and 10 CFR Part 430, Subpart B, Appendix U. On or after January 23, 2017, manufacturers of ceiling fans must make any representations with respect to energy use or efficiency in accordance with the test procedure in 10 CFR Part 430, Subpart B, Appendix U. DOE also specifies, in 10 CFR 430.32, design requirements for ceiling fans, and for ceiling fans manufactured on or after January 21, 2020, minimum efficiency requirements.
