we are going to certify a businesspark consisting 30 buildings of the same type under LEED C&S in v4. Therefore the volume program seems to be very applicable.

However USGBC states on http://www.usgbc.org/cert-guide/volume that it is only available for NC, CI, RN, etc. but not for CS.
Is this information still valid, especially for v4?
What is the reason to exclude CS?

Thanks ind advance.
