More than four years after its predecessor, and one year later than originally planned, LEED v4 will be launched at Greenbuild 2013. Was the wait worth it?
Society for College and University Planning (SCUP)'s insight:
The USGBC built in an overlap period, until June 1, 2015, in which projects can be registered to become certified under LEED 2009 or LEED v4. Then there's no wading back.
