The U.S. Green Building Council (USGBC) has released a draft of the next version of the LEED rating systems, and has opened the first public comment period for that draft. The comment period will run from Nov. 8, 2010, to Dec. 31, 2010. According to USGBC?s website, a second public comment period is expected in mid-2011, and the rating system itself is expected to be released in November 2012. Although it had been dubbed ?LEED 2012? informally during development, after the current ?LEED 2009? system, the new version of the rating system is officially unnamed.
USGBC released the draft to EBN just before the public comment period was to open. Our analysis of what?s (mostly) the same, what?s different, and what?s totally new follows. We focused our analysis on the LEED for New Construction (LEED-NC) rating system, but readers should see the rating system draft for all the rating systems, including details on LEED-NC that we didn?t have space to discuss.
