First of all, I’m sorry for posting a question of the v2.0 Guide in the 2009 page, but there is no space for CS v2.0 projects anymore. I am working on a Core&Shell v2.0 project where an efficient blow-out fixture (short flush = .8 (gpf) and full flush feeds water under pressure, continuously) has been installed, but the Core&Shell v2.0 Guide does not provide a blow-out fixture baseline while the 2009 Guide does. What should I do in this case? Could I use the 2009 baseline case (3.5gpf) to submit a project that is v2.0? or I cannot attempt to this credit because the v2.0 guide does not have a baseline case for blow-out fixtures?

You are correct. LEED-CS v2.0 does not provide a blow-out fixture baseline. The project may attempt to use the 3.5 gpf baseline listed in the 2009 Reference Guide, but I would recommend submitting a LEED Interpretation to the GBCI in order to get clear direction on how to document the project’s water use reduction with this specific fixture.
