The National Appliance Energy Conservation Act of 1987 (NAECA; Pub.L. 100–12, 101 Stat. 103, enacted March 17, 1987) is a United States Act of Congress that regulates energy consumption of specific household appliances. Though minimum Energy Efficiency Standards were first established by the United States Congress in Part B of Title III of the Energy Policy and Conservation Act (EPCA), those standards were then amended by the National Appliance Energy Conservation Act of 1987, the Energy Policy Act of 1992 and the Energy Policy Act of 2005. All of these laws and regulations have to do with creating mandatory standards that deal with the energy efficiency of certain household appliances. These standards were put in place to ensure that manufacturers were building products that are at the maximum energy efficiency levels are that are technically feasible and economically justified.
