[Bldg-sim] PSZ-AC

[Chris Jones]

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.
