[EnergyPlus_Support] Re: AHU exhaust more than supply

It is a very relevant question that I have been wondering myself as well. I want to say that it is possible to insert an exhaust fan in the return air stream. Energyplus can do it. But for the unbalanced fresh/exhaust air, I'd be curious if anyone could have done that (perhaps using EMS?). Because it seems to me that the outdoor air mixer is simply ruled by Fresh = relief and return = mixed.

Am I right? wrong?

Adjusting the pressure rise of the fan will take into account the energy of the exhaust fan, but what happens in the case of unbalanced flow entering the model from an infiltration object? does it go out the AHU exhaust? Heatrecovery could be in the system.
