[EnergyPlus_Support] Re: DOAS without return/relier air

["denergyplus" <denergyplus@xxxxxxxxx>]

Thank you very much Rechard !

But the thing is, where the air exits the building matters in my model, becuase it's a multizone air flow model. That is, the OA exits through the internal window to the next zone which is an atria as a chimney effect.

Is there a way that I can make the air flow to start from OA mixer--> zone 1 --> zone 2(atria), not allowing return air or exhaust fan operation? 

Thank you in advance!
