I have submitted two projects for LEED C&S. In both cases the budget
case was assigned the PSZ-AC system. I used one system per zone
regardless of how the proposed model systems were assigned
zones. The proposed designs both had multiple zone systems. The
LEED reviewer agreed with how I modelled the baseline case.
