LEED, which is an acronym for Leadership in Energy and Environmental Design, was developed by the United States Green Building Council for the design of high-performance, sustainable buildings and interiors. The LEED ratings system is a widely used set of standards for evaluating sustainable, environmentally responsible facility design and construction.
The LEED Building Rating System is organized into several categories:
- Energy and atmosphere
- Indoor environmental quality
- Innovation in design
- Materials and resources
- Sustainable sites
- Water efficiency
There are four different types or classifications of LEED standards:
- LEED-NC: for new construction and major renovation projects.
- LEED-EB: for existing building operations and maintenance.
- LEED-CI: for commercial interior projects.
- LEED-CS: for core and shell projects, such as the structure and foundations, the mechanical or HVAC systems, or the building exterior.
The Rating System is based on a project checklist containing 69 items, each worth one point. There are four certification categories:
- Certified: at least 26 points plus documentation.
- Silver: at least 33 points plus documentation.
- Gold: at least 39 points plus documentation.
- Platinum: at least 52 points plus documentation.
