Abstract
Abstract Minimum energy performance standards (MEPSs) have been adopted in several countries to promote energy efficiency. This study evaluates the impacts of Law 10.295/2001 which regulates the efficiency of equipment in Brazil. This impact assessment was based on estimates of the amount of equipment in operation and the effect of MEPS on a representative model of equipment, in some cases considering efficiency degradation and operation conditions different than those assumed in efficiency measurement. Setting MEPS for refrigerators, air conditioners, and electric motors resulted in an estimated 182.8 GWh savings and 70 MW demand reduction in 2010, which is relatively low due to the limited number of models removed that are affected. The energy saved due to MEPS adoption for gas stoves and water heaters was estimated at 9575 toe (401.0 TJ) 1 in 2010. The projections for 2030 indicate a more substantial impact.
