GBCI recognizes excellence in green building practise and performance globally through its third-party certification services and professional credentials supporting market transformation.


The Green Building Certification Institute (GBCI) is an independent, third-party organization committed to ensuring precision in the design, development, and implementation of the processes used to increase and measure green building performance (certification) and green building practice (credentialing). Established in 2008 to administer project certifications and professional credentials and certificates within the framework of the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) Green Building Rating Systems, GBCI offers the marketplace the highest-level validation that LEED building certification and LEED professional credentials have met specific, rigorous criteria.

Professional Credentialing

GBCI provides balanced, objective management of the LEED professional credentials, including the LEED Green Associate and LEED AP credentials, through structured exam development, application, registration, and delivery.
