RE: [EnergyPlus_Support] infiltration rate
Good question. The COMIS airflows are calculated independently of any pressure
imbalances imposed by the HVAC system. The COMIS model has no knowledge of
whether the HVAC system is operating or not. The ADS model can model this
interaction if this is important. See example files ADS_COMIS_House.idf and
ADS_COMIS_SmallOffice.idf.
