Buried towards the bottom of an 05.04.09 email (I'm a little late here) from Peter Templeton of the GBCI, there was a rather unfortunate announcement:
"Effective June 26, 2009, credit interpretation requests (CIRs) submitted by any registered project will no longer be vetted by USGBC or its LEED Technical Advisory Groups. As a result, CIR rulings will now be applicable only to the project that submitted them. For LEED version 2 projects, rulings on CIRs submitted prior to June 26, 2009, will be honored until they are retired by USGBC or incorporated into general USGBC-issued project guidance, such as through errata or addenda."
This blog relies heavily on the public rulings (see forthcoming post on regularly occupied space for residential buildings), which have cleared up issues for me more often than I care to admit. Equally curious is who exactly will be reviewing the CIRs from this point? One would assume it's the review team for your project, but it's not expressly stated.
