[TRNSYS-users] Type 56 boundary wall with window

[Adrien JEZEQUEL - ITF]

Dear Erik,

You can also define your wall with Identical BOUNDARY condition, and 
define your window as an "additionnal window" which will be adjacent.

I think you may also define your wall as boundary and put a wall gain, 
which will be equal to your window solar gain (you may model that in 
Studio outside Type 56 and define that gain as an input in your type 56)

If you define a ficticious zone on the other side of the wall, you will 
have to define 2 walls - at least - in that zone.

Best regards
