LEED® Standards: What are they?
The LEED® ratings system is a widely used set of standards for evaluating sustainable, environmentally responsible facility design and construction.
LEED®, which is an acronym for Leadership in Energy and Environmental Design, was developed by the United States Green Building Council (USGBC) for the design of high-performance, sustainable buildings and interiors.
The LEED® Building Rating System is organized into several categories:

The Rating System is based on a Project Checklist containing 69 items, each worth one point. There are four certification categories:
The ratings are based on checklists of specific activities, some required for certification and others optional. Many items contain a minimum threshold for qualification, such as 30% reduction in water use or 75% re-use of the existing building shell. The Innovation in Design category awards points for exceptional performance that exceeds the checklists and/or for innovative performance in green building categories not specifically addressed by LEED®
