Energy-saving benefits of automatic lighting controls
The energy-saving potentials of various control strategies were investigated at two demonstration sites. A continuously dimmable system was installed at the Pacific Gas and Electric building in San Francisco and an on/off switching system was installed at the World Trade Center in New York. Automatically switching the lights on the basis of occupancy reduced daily lighting energy use by 10 to 26%. Using natural daylight to supplement electric lighting reduced lighting energy consumption an additional 16 to 30% in daylit areas. A simple cost/benefit analysis is presented that allows building energy managers to determine the cost-effectiveness of different lighting control strategies for particular design applications.
