The Leadership in Energy and Environmental Design (LEED) Green Building Rating System™ promotes a whole-building approach to sustainability by recognizing performance in five key areas of human and environmental health: sustainable site development, water savings, energy efficiency, materials selection, and indoor environmental quality.
Energy savings offer the most credits of any LEED category. And lighting accounts for about 40% of the energy use of a typical commercial facility. So lighting can contribute directly toward LEED certification. Facility managers are increasingly seeking out high-efficiency lighting solutions, such as fluorescent and compact fluorescent lamps, electronic ballasts, and occupancy sensors—and integrating daylighting into their system where possible to minimize the dependence on electric lighting.
