LEED Rating Systems
Rating systems are groups of requirements for projects that want to achieve LEED certification.
Each group is geared towards the unique needs of a project or building type. LEED is flexible enough to apply to all project types including healthcare facilities, schools, homes and even entire neighborhoods.
Projects earn points to satisfy green building requirements
Within each of the LEED credit categories, projects must satisfy prerequisites and earn points. The number of points the project earns determines its level of LEED certification.
Main credit categories
- Sustainable sites credits encourage strategies that minimize the impact on ecosystems and water resources.
- Water efficiency credits promote smarter use of water, inside and out, to reduce potable water consumption.
- Energy & atmosphere credits promote better building energy performance through innovative strategies.
- Materials & resources credits encourage using sustainable building materials and reducing waste.
- Indoor environmental quality credits promote better indoor air quality and access to daylight and views.
Additional LEED for Neighborhood Development credit categories
- Smart location & linkage credits promote walkable neighborhoods with efficient transportation options and open space.
- Neighborhood pattern & design credits emphasize compact, walkable, vibrant, mixed-use neighborhoods with good connections to nearby communities.
- Green infrastructure & buildings credits reduce the environmental consequences of the construction and operation of buildings and infrastructure.
Additional LEED for Homes credit categories
