A widely recognized and internationally used green building certification program developed by the U.S. Green Building Council (USGBC). It provides a framework for designing, constructing, operating, and maintaining sustainable and environmentally friendly buildings and communities. The goal of LEED is to promote resource efficiency, reduce environmental impact, improve indoor environmental quality, and create healthier spaces for occupants.LEED certification is a point-based rating system, where projects earn points for various sustainable features and practices implemented throughout the design and construction process. The total number of points a project earns determines its LEED certification level. There are several LEED rating systems tailored to different types of projects, such as new construction, commercial interiors, existing buildings, homes, and neighborhood development.
