Developed by the U.S. Green Building Council (USGBC), Leadership in Energy and Environmental Design (LEED) is a green building certification program that helps building owners and operators be environmentally responsible and resourceful. Using a rating system for design, construction, operation, and maintenance, construction professionals, engineers, and building owners lean on the LEED® framework to ensure buildings, homes, and facilities are developed and maintained with safety, health, efficiency, and cost-savings in mind. Metrics like energy savings, water efficiency, and CO2 emissions are just a few of the sustainability areas taken into consideration during the LEED® certification process. Using a point-based system, the more points accumulated by the building, the higher the level of certification. The LEED® program, developed by USGBC, is internationally recognized.
