Solar and visual absorptance for EP simulation

@kimtse1 ,

I’m sorry that this is too large of a file for me to figure out where the material reflectance is differing between the Grasshopper definition and the IDF. Can you send me as small of a Grasshopper definition as is needed to recreate the error? Devang makes note of this in the forum guidelines that he wrote and it really helps us figure out what the issues are.
