Re: [EnergyPlus_Support] COMIS and PA

["Michael J. Witte" <mjwitte@xxxxxxxx>]

The key point is that the COMIS simulation calculates airflows for infiltration 
and zone-to-zone mixing without any knowledge of HVAC system flows.  You can 
use COMIS to ventilate and use PURCHASED AIR to calculate the heating/cooling 
loads.
