U.s. Green Building Council: Leadership in Energy & Environmental Design

LEED is a program for green building certification. Buildings are rated on a points system in one of five categories, including building design and construction, interior design and construction, building operations and maintenance, neighborhood development, and homes. The impact of a building on people's health and the environment are paramount to getting certification.
