I know a lot has been said about modelling airflow through windows and doors, but i want to ask a very specific question. Is it possible to model airflow between two zones(Not between a zone and ambient). Let us say i have an opening on a door between two zones and i want to model the effect of airflow on the ON and OFF cycles of the HVAC, is it possible to do this using ZoneVentilation:WindStackOpenArea? The airflow network seems a bit complex for me that is why i am trying to avoid it at the moment.
