LEED for Homes: United States Green Building Council
LEED for Homes is a voluntary rating system that promotes the design and construction of high-performance green homes. LEED is an internationally recognized green building certification system which provides third-party verification that a building or community was designed and built using strategies aimed at improving performance across all of the metrics that matter most: energy savings, water efficiency, CO2 emissions reduction, improved indoor environmental quality, and stewardship of resources and sensitivity to their impacts.
