Most people in the construction industry are familiar with the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) system. LEED is the most widely known "green" building certification system. Since the LEED program began in 1993, more than 44,000 projects have been registered and/or certified in the U.S.
Despite its success, the LEED system is not without its critics who say the program is too expensive; the certification process takes too long; the documentation necessary for project certification is too bureaucratic and time-consuming; and energy savings predicted in LEED system modeling are not always achieved in actual building operations.
Other green building certification systems in the U.S. are beginning to gain traction. The most established of these alternative systems is the Green Globes Environmental Assessment and Rating System—commonly known as Green Globes. In 2004, the Green Building Initiative (GBI) acquired the U.S rights to the Green Globes building assessment and certification program and adapted it for the U.S. market as an alternative to the LEED building rating system.
