- Abstract
- Lighting in commercial buildings is the single largest user of electric energy, typically ranging from 25 to 50 percent of total building electrical energy requirements. In 1980, 2.8 x 10(15) Btu of energy was used for lighting, for a total cost of over $40 billion annually. Therefore, an overall increase in lighting efficiency of one percent would produce a savings of $400 million a year.
