You can define the coupling air flow in whatever way you like. As long as there is an adjacent surface between two zones (whether a wall or a window) you can define some air movement through that surface. You could have all the coupling air go through the wall, all of it go through the window, or you could split it in whatever proportion you like. The total air flow from one zone to the other is going to be the sum of all the individual air flows.
Also keep in mind that if you define air flow in one direction (zone A to zone B for example) this does NOT mean that there is a corresponding amount of air assumed to flow from zone B back to zone A; you must specify that separately.
Best,

Hi trnsys users,
in adjacent wall, you can define coupling air throw wall and window, if the wall has a window. If there is coupling air throw window, I understand it is not necesary to define it in wall, only in window. Am I right?
