LEED 2009 will represent a reorganization of the existing LEED rating systems and will include a series of major technical advancements focused on improving energy efficiency and reducing carbon emissions, according to the U.S. Green Building Council (USGBC).
Possible changes also include weightings of LEED credits so the highest-priority credits achieve the most points, a new mechanism for incorporating bioregional credits, and a more nimble framework that supports rapid response to emerging environmental and human health issues.
LEED 2009, coupled with an expanded third-party certification program and significant enhancements to LEED Online, make up a multi-faceted initiative referred to as LEED Version 3.0.
The first public commentary period for a new version of LEED recently closed. USGBC has said it will review the comments, make revisions and then open LEED 2009 for a second comment period later this year. Then members will vote on the final draft.
