System Overview

Lighting accounts for about 17% of the total electricity consumption of commercial buildings in the United States.1 Effective lighting systems involve the integration of lighting technologies with the building as a whole – across the lifecycle of a building. Green technologies and design strategies are more conducive to energy and financial savings, and improved human health, productivity, and satisfaction.

Cost Savings

U.S. buildings spend more than $37 billion annually on electricity for lighting. Significant savings are possible through more efficient lamps, lighting controls, and better use of daylighting.
