Re: [TRNSYS-users] TRNSYS3D Variable Shading?
Graham,
I do not think it is possible to vary the transmittance of a Trnsys3D
object. You might be best off using type67 to assess the reduction in
incident solar radiation on your building facades. While type67 itself
assumes that shaders are totally opaque when calculating shaded
radiation, it also outputs the raw shading fractions for beam and
diffuse radiation. Multiplying these by a non-zero transmittance would
get you your partial shading.
Kind regards,
David

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!
Graham Linn
