I have two cases; one is a retail where they dont have door (they have the gap without door, they never close a door); another one is a chicken farm, where they have long windows without crystal.

I started using an air wall with a very high infiltration to simulate mass transfer. I have never been sure about this solution.

I have found ZoneVentilation:WindandStackOpenArea object, which I think of suiting better to my cases. I also have seen AirflowNetwork object, but it needs a detail that I'll not define now.

I have doubts about ZoneVentilation:WindandStackOpenArea. It is associated to a thermal zone, not to a door or window. Then, in my case where I dont have crystals; how do I have to define the windows and doors? as an air wall or as normal windows or doors? I am not sure if defining a door as a air wall and using ZoneVentilation:WindandStackOpenAreaI'll be considering twice thermal transfer accroos the windows or doors.

I knew ZoneVentilation:WindandStackOpenArea reading that post. Really, it hasnt meaning to think in heat transfer because of exterior and interior temperature diference when the door is open, and there isnt heat transfer surface. Temperature is going to affect in the stack effect (ec. 1.38, page 584, in InputOutputReference). Thus, iin my case, door is always open, and it is indiferent about what material has the surface.
