The United States Green Building Council’s (USGBC) Leadership in Energy and Environmental Design (LEED^®)program sets a definitive standard for what constitutes a ‘Green Building’. The program is based on nationally accepted energy and environmental standards and principles that strike a balance between known effective practices and emerging technologies. The U.S. Green Building Council is the governing body for LEED^® and is the nation’s foremost coalition of leaders from across the building industry working to promote buildings that are socially and environmentally responsible, profitable, and healthy places to live and work.
