I think you will have to be a little creative here. Shading
devices in Trnsys3D are assumed to be opaque as you know so I don't
think you can define the shading surface in there. You could use
Type34, which models simple overhangs and/or wingwalls. That model
also assumes an opaque shader but it gives outputs for various
shading fractions and view factors. You may be able to use those and
the unshaded radiation from your weather component to get an
estimate of the radiation that comes through your not-quite-opaque
device. Lastly, Type56 allows you to enter a shading factor for any
given window. You may be able to treat your shaders in that manner.<br>
<br>
Unfortunately, there is not a direct way to treat semitransparent
shaders unless you would care to modify Type34.<br>
Kind regards,<br>

I have posted a picture that show my 3d model in sketchup; so, as
you can see, all of the triangular surfaces (into red circle), are
made in perforated corten steel, and i need to give a shading
coefficient to their, otherwise the program will do the
simulations considering the shading surfaces opaque; but actually
they are not matt.

<br>
if someone have any ideas about how I can do.....
