LEED Certification Developed by the U.S. Green Building Council (USGBC), the Leadership in Energy and Environmental Design (LEED) is a green building certification program focused on the design, construction, operation, and maintenance of green buildings, homes, and neighborhoods, which aims to help building owners and operators be environmentally responsible and use resources efficiently. LEED certification is a globally recognized symbol of sustainability achievement and leadership. To achieve LEED certification, a project earns points by adhering to prerequisites and credits that address carbon, energy, water, waste, transportation, materials, health and indoor environmental quality. Projects go through a verification and review process and are awarded points that correspond to a level of LEED certification: Platinum (80+ points) Gold (60-79 points) Silver (50-59 points) Certified (40-49 points)
