I am facing a problem, and cannot decide which method should be used to solve it.
The problem, in itself is very simple:
How do you take into account the solar gains for a building with this type of solar protection :

It's a textile at about 1 meter from the facade. My building is different: the textile covers almost entirely the facade, except for several windows reserved for firefighters access. This textile is semi transparent.
Here my questions:
1/ Does this textile should be taken into account for solar gains' walls ?
2/ Is a simple solar factor sufficient? Tha fact that it's about 1 m from the facade does not interfer?
3/ How to take into account the openings in the textile in front of several windows?
I was thinking of creating a solar mask element in 3d with Tnrsys 17. But this mask, as far as I know is opaque...
This building has very low heating needs, so the way we take solar gains is very important...
Thanks in advance.
