Green Building Certification Institute (GBCI)

The Green Building Certification Institute (GBCI) provides third-party confirmation that specific criteria related to LEED building certification and LEED professional credentialing have been met. To underscore this commitment, GBCI is undergoing the American National Standards Institute (ANSI) accreditation process for personnel certification agencies complying with International Organization for Standardization (ISO) Standard 17024. Early in 2009, GBCI assumed responsibility for administering the LEED building certification program for the more than 36,000 commercial projects seeking third-party verification of compliance with the industry's leading green building rating system.
