Michele,
There are two tools available for determining the quantity of coupling airflow. One is Type97 (or Type98) (both of which are links between TRNSYS and a freely available software tool called CONTAM). The other is a commercially available TRNSYS add-on called TRNFlow. The idea behind both is that the Trnsys building thermal model (Type56) provides zone temperatures to the airflow model (CONTAM or TRNFlow). The airflow model takes those temperatures (as well as ambient conditions and a certain amount of building geometry with which the thermal model is not usually concerned) and computes the corresponding interzonal air flows. These are passed back to Type56, which recomputes zonal temperatures. Iteration continues until both the thermal and airflow models agree.
kind regards,
David

Hi, I m designing a church with different thermal zones and the common surfaces are set to virtual surface. I activated the coupling . What would be the ideal coupling air flow?
