[EnergyPlus_Support] Modelling of exterior fixed louvres

["josh_miarch" <jeemang@xxxxxxxxx>]

I'm wondering about the best approach to take to model a shading
device of the following composition: 

-consists of ~20 fixed louvres that span the width of the window. 
-louvres are arranged on a slope, such that the uppermost louvre at
the top of shading device is closer to the window face (237mm from the
window face at a height level with the window head) than the louvre at
the base of the sunshade (986mm from the window face at a height of
529mm above the window sill)
-louvres between the uppermost and lowermost louvres are spaced evenly
and linearly. 

My questions are: 

1. Should I simply model in the geometry of the shades directly and
use Surface:Shading:Attached, or will that result in a ridiculous
amount of processing time?
2. Are there any ways to approximate the effect of a shading device
like this that won't excessively compromise the accuracy of the
simulation?

Thanks a lot,

Josh
