I am an advocate for raising the bar.
However, significant market buy-in has not occured. We need to stay at LEED 2009 levels for more than just 2 years. It should be more like 5. In this economy it's harder than ever to convince developers, owners, municipalities etc to buy into LEED.
I feel that USGBC/GBCI should wait a year or more to move into the next evolution.
My firm's primary client is the DOD who has stipulated that LEED 2009 Silver is a mandate, but now Gold-Platinum can not cost more and will not be considered a betterment. Gold and Platinum have been devalued erroniously becasue the Federal Government doesn't really understand it after 7 years.

LEED 2012 will most certainly have DOD and other Federal Agencies jump ship, not to mention those in the private sector. I emplore the community to encourage usgbc/gbci to wait for the next rollout. I would like to see LEED 2014 as version 4.
