Solve Adjacencies with AIR WALL + Adiabatic

Hey All!

I have solved adjacencies of two zones (one on top of the other, as parts of a double-skin facade) with AIR WALL as alt-Construction, and Adiabatic as alt-Boundary-Condition. I’d appreciate if someone could explain the behavior of such surfaces in terms of heat transfer as well as causing shading effect on other objects.

I guess such surfaces should let the sun in, while not letting heat transfer between their two sides. Is that correct?
