USGBC has opened the fifth—and, it expects, final—public comment period on LEED v4, the next version of the LEED rating system. The system was referred to as "LEED 2012" for most of its development, but after the fourth public comment period (see discussion on that comment period and draft) ended with a sense among USGBC membership that the system was not ready for a member ballot, USGBC changed the rollout schedule and the name.
The public comment period is open from October 2, 2012 through Dec. 10, 2012, with the ballot planned for June 1, 2013. Anyone can submit public comments on the LEED v4 draft here or on the USGBC website, where you can also see the proposed language, credit by credit. Please post your comments on LEED v4 below!
Now that the final form of LEED v4 is taking shape and the direction that it is taking is clear, the team here at LEEDuser has written a special report to guide you through potentially confusing new concepts like EPDs, REACH, BUG ratings, and their place in LEED certification.
