I was not aware of the 'ZoneHVAC:IdealLoadsAirSystem' object-it looks promising.
I am trying to implement a pre-existing EnergyPlus model in another simulation environment, so ideally I would not have to change the EnergyPlus model, but instead just extract the results that an IdealLoadsAirSystem would produce.
That being said, I can definitely delete the existing HVAC system and use the IdealLoadsAirSystem in a new file if an easier approach is not available. Thanks!
