The U.S. Green Building Council (USGBC) announced that a fifth
public comment period on proposed updates to the LEED (Leadership
and Energy and Environmental Design) green building rating systems
will run from October 2, 2012, to December 10, 2012, with
submission of the proposed changes to a vote by the USGBC
membership scheduled for June 1, 2013.
As noted in a prior blog post, LEED v4 was previously known as LEED
2012. LEED 2012 had been scheduled for a vote in June
2012, with a launch to take place by the end of the year.
However, balloting was deferred first to August 15, 2012, and then
to June 1, 2013. In announcing the delay, the USGBC
President commented that "we have heard repeatedly that while
our community continues to fully embrace our mission, they need
more time to absorb the changes we're proposing and to get
their businesses ready to take the step with us."
The USGBC website summarizes the anticipated changes as
New market sectors: data centers, warehouses
and distribution centers, hospitality facilities (i.e.
hotels), existing schools
and existing retail, and LEED for Homes Mid-Rise.
Increased technical rigor: revisions to credit
weights, new credit categories focusing on integrated design, life
cycle analysis of materials, and an increased emphasis on
measurement and performance.
Streamlined services: An improved LEED user
experience that makes the LEED Online platform more intuitive and
introduces tools to make the LEED documentation process
Thirty-seven credits are up for comment, including several
relating to "Building Product Disclosure and
Optimization" that are characterized as "major
changes." Some of the materials credits
have been particularly controversial. There will
undoubtedly be a number of public comments.
