Established by the U.S. Green Building Council, Leadership in Energy & Environmental Design (LEED) recognizes buildings and neighborhoods that save energy, use fewer resources, reduce pollution, and contribute to healthier environments for their occupants and the community. The level of LEED certification earned is determined by the number of credits achieved in key areas within each of the LEED credit categories, including sustainable sites, water efficiency, energy & atmosphere, materials & resources, indoor environmental quality and innovation & design process.
