LEED 2012 Postponed Until 2013, Renamed LEED v4

June 7, 2012 from American Institute of Steel Construction

In response to growing concerns from the building market, the U.S. Green Building Council (USGBC) has announced that it will postpone ballot on the LEED Rating System Development (LEED 2012) until as late as June 1, 2013. Because of the date change, the new version of LEED has been renamed to LEED v4.

The delay comes from a lack of readiness voiced by building industry professionals, many of whom are LEED users. USGBC will use this time to provide the marketplace with a full understanding of the new program prior to ballot, and will keep LEED 2009 available for three more years while the industry gradually moves to LEED v4.

“USGBC has taken a wise step back here,” commented John Cross, AISC’s vice president of marketing. “LEED 2012 contained many concepts that certainly raise the bar for green buildings, but those concepts were not necessarily well integrated with each other and current industry practices. The additional year provides a real opportunity for USGBC to not only publish the ‘greenest’ version of LEED, but also the one that will be the most accepted and used.”

In addition to the ballot date change, USGBC is committing to a fifth public comment period that will run from October 2 to December 10, corresponding with this year’s Greenbuild conference in San Francisco (which takes place November 14-16). Public forums and educational sessions will be held to help stakeholders better understand the next draft, and the event will also serve as a platform to debut new resources designed to enhance the LEED user experience.

USGBC President and CEO Rick Fedrizzi has issued a public statement about the LEED 2012 postponement, available on USGBC’s website at www.usgbc.org (direct link: http://bit.ly/NP0D8F).
