Revision history [back]

I am working on modifying DOE reference buildings with new types of HVAC, but first am attempting to replicate the results of the METER output data from the DOE IDF within Open Studio. I am not seeing the item AirLoopHVAC:UnitaryHeatCool in Open Studio 8.3, but am currently using AirLoopHVAC:UnitarySystem instead. I am not getting matching results for the cooling electricity usage even when setting the electric reheat for this system to zero. Still using Fan:OnOff, DX CoolingCoil Single Speed, and gas heat. Can anyone explain the differences between AirLoopHVAC:UnitarySystem and AirLoopHVAC:UnitaryHeatCool so that I can better find a solution for my problem?
