[TRNSYS-users] TRNSYS3D Variable Shading?

[Graham Linn <grahamjlinn@gmail.com>]

Good Day TRNSYS community,

I would like to simulate a shading garden wall in TRNSYS. (Think of a
curtain wall but the outer layer is just a trellis with vines growing
on it.) Can I draw a shading wall in TRNSYS3D and vary its
transmittance based on time of the year? Or do I have to use some kind
of other shading factor input?

I would like the garden wall to cover areas besides just windows.
However, I cannot figure out how to vary the transmittance for
TRNSYS3D shading surfaces.

Thank you!
