Leadership in Energy and Environmental Design (LEED) is a voluntary green building rating system originally developed in the United States by the U.S. Green Building Council (USGBC). In Canada, the program has been adapted and is administered by the Canada Green Building Council (CaGBC). There are five principal LEED credit categories, including: Sustainable Sites, Water Efficiency, Energy and Atmosphere, Materials and Resources, and Indoor Environmental Quality with four possible levels of certification (certified, silver, gold and platinum). In addition, there are different building categories such as New Construction, Existing Buildings, Core & Shell, Commercial Interiors, Retail, Homes, Neighbourhoods, Schools, and Healthcare. While some have criticized the rating system for being bureaucratic, it has been instrumental in bringing awareness to sustainable architecture and raising the standards of building design & construction.
