Developed by the U.S. Green Buildings Council, the Leadership in Energy and Environmental Design (LEED®) Green Building Rating System advances the adoption of sustainable green building and development practices through the implementation of universally understood and accepted tools and performance criteria. LEED® promotes a whole-building approach to sustainability by acknowledging performance in five crucial areas of human and environmental health: sustainable site development; water savings; energy efficiency; materials selection; and indoor air quality.
