Bilevel switching, in which alternate rows, fixtures or lamps are separately circuited and independently controlled, has been demonstrated in one study to produce 22 percent energy savings in private offices.
The U.S. Department of Energy (DOE) predicts that solid-state lighting will achieve efficacies as high as 160 lumens per watt and provide most of our general lighting needs within the next 20 years, thereby reducing the nation’s energy costs by 6–7 percent.
Between 1984 and 2003, the percentage of people directly using a computer at work more than doubled to nearly 57 percent. The widespread adoption of computers not only changed office environments but also best practices in lighting and, by extension, office lighting technology.
