The draft of LEED 2012 will open for a 4th public comment on May 1. The draft of LEED 2012 will incorporate final technical revisions based on public comment feedback, and will incorporate credit requirements that have been positively impacted by credit documentation development. Credit documentation, reference guide and education development will continue concurrent with the public comment and ballot. Public engagement opportunities to provide feedback and assist in the refinement of this work will be announced later in April and throughout the ballot period. The 4th public comment period will run May 1 until May 15. Once the comment period process concludes, LEED 2012 will be balloted from June 1 until June 30, and launch in November.
