The purpose of this report is to offer an objective summary of selected green building certification systems based on specific criteria. The review criteria were derived from EISA, the Guiding Principles for Federal Leadership in High-Performance Sustainable Buildings, other legal drivers of Federal green building, and the experience of Federal personnel who have used the certification systems. Publicly available information, both free and for purchase, was examined to document certification system information and to map each system to the review criteria. The certification system owners were offered an opportunity to provide additional information in response to the review criteria. Federal personnel who have had experience using green building certification systems were interviewed to offer anecdotal
information about their use of the systems.
