No country has directly measured the actual energy savings resulting from efficiency standards, but many studies--mostly in North America--have indirectly observed savings. Methodological and practical obstacles to observing savings include the difficulty of defining baseline energy use and isolating the impact of technical improvements in efficiency from other changes in usage patterns. Laboratory...
An energy test procedure is the technical foundation for all energy efficiency standards. It provides manufacturers, regulatory authorities, and consumers a way of consistently evaluating energy use. The ideal test procedure reflects actual usage conditions without compromising reliability and cost-effectiveness. Unfortunately, because these goals are contradictory, every test procedure is a compromise...
