Uh, what? Not sure what you are asking for here. You can calculate daylight factors in Radiance (for what they are worth), daylight coefficients, and all kinds of metrics. "Window cleanness" can be approximated by applying a factor the the transmissivity of the glazing, which is what Radiance expects as input. Glazing properties such as transmittance, reflectance, color and now even BSDFs can be derived from the Window6 program from LBNL.

Hello everyone. Could you please tell me if there is any crude valu in Radiance, similar to other daylight prediction or simulation methods like daylight factor correction values such as window cleanness or glass light absorbance?
Thanks alot.
