USGBC Moves to Improve LEED v4

LEED v4.1, a new iteration of the green building rating system will be piloted in 2018 with the goal of smoothing over rough spots.

The latest version of LEED, LEED v4, became mandatory a little over a year ago. That was just after the U.S. Green Building Council’s 2016 Greenbuild conference. This year at Greenbuild, USGBC announced that it is fast-tracking development of a new iteration, LEED v4.1.

“LEED v4 has been out a long time,” says Corey Enck, director of LEED technical development at USGBC, told BuildingGreen. LEED v4’s development path started in 2009 and eventually stretched through six public comment periods and a beta program that began in 2013, before the system became mandatory in 2016 (see LEED 2012 Postponed to 2013, Renamed LEED v4). “A lot of the things we wrote into that need a bit of a refresh,” says Enck. “We need to make sure that LEED is still relevant and is still the leadership standard.”
