Thread-topic: Problem with adjacent window

Hi Toni

You can choose the orientation of the window (Front/Back). Perhaps the window direction points into the living space. This is important because you can only define interior shading in front of the window.

David

Betreff: [TRNSYS-users] Problem with adjacent window

Hi,

I am working in Trnsys18. I have a building model with two thermal zones (Wintergarten and one room) with an external window for the wintergarten and an adjacent window between the two zones. If I set the external shading factor of the external window to 1, I have no solar gains in the two zones, as it should be -> CORRECT!

I tried then to shade just the adjacent window between the two zones (int. shading factor of 1 in TRNBUILD) and I expected solar gains just in the wintergarten, but not in the room. I got solar gains in both zones. It seems that I am not able to shade completely just the adjacent window.

Which is the problem?
