Abstract

This report provides background data upon which residential lighting fixture energy conservation programs can be built. The current stock of residential lighting is described by usage level, lamp wattage, fixture type, and location within the house. Data are discussed that indicate that 27% of incandescent residential fixtures are responsible for over 80% of residential lighting energy use, and that justify targeting these fixtures as candidates for retrofit with energy-efficient fixtures. Fixtures determined to have the highest energy use are hardwired (1) ceiling fixtures in kitchens, portable fixtures in living/family rooms, hardwired fixtures in dining rooms, and hardwired fixtures outdoors. An assesment of the market for residential fixtures shows that nearly half of new residential fixtures are imported, about 60% of new fixtures sold are hardwired, and about half of all new fixtures sold are for ceiling installation.
