April 27 will also be the date for the transition of LEED project registration and certification to the Green Building Certification Institute
(GBCI), the third party that administers the LEED Accredited Professional (LEED AP) certification, the story stated.
According to the story, projects may be registered under either the new or the old LEED rating system until June 27, 2009, from which point all projects must be registered for LEED 2009.
Several versions of previous LEED AP exams will be retired and new versions will be introduced and made mandatory, the story noted.
The LEED 2009 credentials are more strict and offer extended levels of accreditation, the story added.
