Hi,

How can I make a central DOAS system (OA Ventilation) to provide OA for several AHUs? The DOAS only provides variable OA to the AHUs in each floor. The DOAS also has pre-heat coil and cooling coil to Keep the OA temperature at 50F.

Is it possible to do that in EnergyPlus or it should be a DOAS system per AHU for each floor?

The AHU includes VAV series fan powered boxes with electric resistance coils.
