The Leadership in Energy and Environmental Design (LEED) is being encouraged and accelerated globally due to creation and implementation of accepted tools and criteria of environmental performance (Hodge, 2004). Leadership in Energy and Environmental Design refers to a third-party certification program and a known benchmark for operation, construction and design of green buildings of high performance. Leadership in Energy and Environmental Design -Gold certification is recognized as the second highest in the system.
Whole- building approach to sustainability has been promoted by Leadership in Energy and Environmental Design due to its consideration in five key areas: water savings, sustainable sites, materials and resources, energy and atmosphere and indoor environmental quality. Environmental impacts have been reduced by identifying and managing environmental footprints in Canada as given by the LEED. Leadership in Energy and Environmental Design has enabled building owners and operators in Canada to have an immediate and measurable result on performance of buildings (Statistics Canada, 2004).
