LEED-NC 2.2 Approved

In balloting that closed on October 28, 2005, the membership of the U.S. Green Building Council (USGBC) voted overwhelmingly to approve version 2.2 of USGBC’s flagship LEED^® for New Construction (LEED-NC) rating system. While other versions of LEED have been released in the interim, this vote endorses the first substantive update of the NC rating system since version 2.0 was released in May of 2000. (LEED 2.1, containing only administrative changes, was released without member ballot.) LEED-NC 2.2 will be formally released on November 11 at Greenbuild in Atlanta. Projects can be registered under LEED-NC 2.0/2.1 until December 31, after which registrations will be accepted only for 2.2. (Previously registered projects will still be able to apply for certification under the older systems.) A new exam based on LEED-NC 2.2 is expected in July of 2006.
