LEED (Leadership in Energy and Environmental Design) is a benchmark for the design, construction, and operation of green buildings. It provides building owners tools to improve building performance in areas like energy savings, carbon savings, water use reduction, and cost savings. LEED aims to promote sustainability through establishing standards, recognizing environmental leadership, and stimulating green competition to raise awareness of green building benefits and transform the building market.
