I want to model the net solar gain of exterior louvers. Their dimensions and spacing can be relatively close. I want to be sure that despite their size, the shadowing and inter-reflections between slats gets accurately modeled such that the net solar gain on the interior space is accurate. (I'm aware of the BSDF alternative but am exploring straight geometry input as an alternative).
Does this statement in the Shadowing Module section of the Engineering Reference document mean that I can model shadow and reflection for exterior surfaces that are at least 1 mm between all vertices?
Note that the resolution on surfaces/shadowing is 1 mm – using resolution beyond that will result in truncation of the shadowing.
