Lighting in commercial buildings accounts for close to 71 percentage of overall lighting electricity used in the U.S. Lighting consumes close to 35 percentage of the electricity used in commercial buildings in the U.S. Lighting systems produce large amounts of heat as well as light. Lighting is the largest source of waste heat (HEAT GAIN) inside commercial buildings. Finally, lighting is the single largest cost component of a commercial building’s electricity bill!

WHICH IS MORE COST EFFECTIVE AND TIMELINESS? RESIDENTIAL ENERGY SAVING? RENEWABLE ENERGY? OR LIGHTING RETROFIT FOR COMMERCIAL BUILDINGS?
