The US Green Building Council has announced that the planned revision of the LEED green building system which was due later this year has now been delayed until at least the middle of next year. What was supposed to be called LEED 2012 is being renamed LEEDv4 (the current version, LEED 2009, was version 3).
LEED is a developing system, not a fixed standard. Previous transformations have revised and reoriented the rating system, and this has helped to advance the cause of green building. The intent of the USGBC has been to continue to push the construction industry to make buildings better. However the present perception is that the new LEED pushes too much, too fast. In his letter announcing the change, USGBC President and CEO S. Richard Fedrizzi wrote, "We intend to do everything we can to ensure that the market is ready for LEED v4 because it represents progress on both carbon reduction and human health improvements."
LEED is getting criticism from many different directions. It has been assailed by Congress, which has specifically prohibited the Department of Defense from expending any funds to achieve LEED gold or platinum certification. Arguments over standards for the certification of wood have been particularly contentious. And just this week, congressional hearings on green building science are being held.
