Does anyone have a workflow to describe how to include a tubular daylighting device (e.g. Solatube) in a daylight calc? In this case a LEED calc. I am not proficient in Radiance so I'm wondering if there are any tutorials on how to include Solatube's .ies files in Diva. e.g. defining the physical TDD geometry & adding a new material or definition to the material.rad file?
Thanks you in advance!
That is not possible unfortunately, especially since right now DIVA cannot output pure Radiance primitives (such as cylinders and spheres) -- only polygons.
What simulation parameters are you using for that 18 hour effort?
Ok, I see. Actually I used the parameters that you proposed in the tutorial but now I went back to the default parameters and it goes much quicker.
