About these LEED® menus and links

This directory of articles, products, and case studies is based on the credits and prerequisites of the U.S. Green Building Council's LEED Rating Systems. "LEED," for "Leadership in Energy and Environmental Design," recognizes the environmental performance of buildings at four levels: Certified, Silver, Gold, and Platinum. LEED certification is the most popular third-party endorsement of a project’s green credentials.

LEED is organized around a list of prerequisites and credits, each of which is worth one or more points. Projects get certified once they have achieved all the prerequisites and accrued enough points—the level of certification depends on how many points they earned.

There are separate LEED rating systems for different types of projects. Most of these certify projects based on their design and construction, for example: LEED for New Construction, LEED for Schools, LEED for Commercial Interiors, and LEED for Homes. One system, LEED for Existing Buildings: Operations and Maintenance (LEED EBOM) certifies projects based on their operational performance. has articles, product listings, and case studies on relating to credits in all the LEED rating systems. You can view all this information, credit-by-credit for the five primary LEED rating systems for non-residential buildings. Information on LEED for Homes in available on our sister website, More specific tips and guidance on achieving each credit, along with a user forum dedicated to LEED, is available on LEEDuser.

You can also view articles about LEED in general, and all LEED-certified projects in our database.

Note that use of this information is by no means a guarantee of earning a credit, and the Green Building Certification Institute is the only organization with the authority to award credits for a project. BuildingGreen staff have participated as volunteers in the development and implementation of this rating system, teach LEED workshops, and consult on LEED projects, so we are quite familiar with it. But it is entirely possible that USGBC staff and its contractors responsible for implementing LEED may interpret the credits differently, and that products we have identified might not qualify. If you notice any such discrepancy, please let us know by using the "send feedback" link in the footer of this or any other page.
