I hope everyone is safe with their families at this difficult time.
I have a question and I hope someone can help point me to the right direction or provide me with a short answer.
I made a few simulations using @chri ‘s examples for the LadayBug Comfort Tutorials.
I would really appreciate it if someone could tell me about the breps’ properties that are set in an outdoor context i. e. transmittance and reflectance, specifically the shade’s bus stop that was set here; (https://youtu.be/yIl2XhOfGUw). What are the standard properties here?
For either of the two shade benefit components (comfort benefit or energy benefit), there are no bounces considered in the analysis at all. Essentially, sun vectors are just shot out from a bunch of points on the bus stop bench or window and the component checks to see if they intersect the context shade, in which case they are ignored. If they don’t hit the context shade, then the component checks to see if it hits a cell of the analysis mesh that is being evaluated for benefit. If it hits the mesh, the “value” of the sun vector (either degrees from comfort or cooling/heating energy) is added/subtracted from the benefit of that cell.
Here’s the paper that outlines the methods used in the comfort shade benefit component:
