Dear all,

I am working on a LEED CS 2009 project on a 2009 Master site. Our ambition is that the next up coming project is to be a v4 project. Now the question is: can a v4 project be certified on a 2009 master site? Or do we have to "re-do" the master site which at this stage is not the preferred option, as the 2009 project is not certified yet.
