Differing supply temperature is one good reason to separate zones. So I would suggest only combining those zones that have the same supply air temperature. The reason is that the coil model behavior will depend on leaving temperature. From: EnergyPlus_Support@xxxxxxxxxxxxxxx [mailto:EnergyPlus_Support@xxxxxxxxxxxxxxx] Hello, all. Then is it possible to combine the zones which have the same load and schedule into one? As I know, the cooling load and air flow rate can be added up after merging the zone. But how to set the supply air temperature? Thanks.
