Leadership in Energy and Environmental Design
About LEED
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 three different types or classifications of LEED standards:
- LEED BD+C: New construction
- LEED O+M: Operations and Maintenance
- LEED ID+C: Interior Design and Construction
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.
