Leadership in Energy and Environmental Design (LEED) is a widely recognized green building certification program that promotes sustainable construction practices. Developed by the U.S. Green Building Council (USGBC), LEED provides a framework for designing, constructing, and operating buildings that are environmentally responsible and resource-efficient. LEED certification is based on a point system, where projects earn points for various sustainable features, such as energy efficiency, water conservation, and the use of sustainable materials. Buildings can achieve different levels of certification, including Certified, Silver, Gold, and Platinum, depending on the total points earned.
