Currently, I am working on my thesis which is to optimize a facade for controlled daylight distribution in an office space of a high rise building for visual comfort. This will deal with redirecting of daylight to a greater depth, diffusing light to reduce glare near to window, and facade that reacts with the dynamic behavior of daylight throughout the year.
For this, I am using HB+ and LB+ plugins for daylight simulation. I also went through the 3-phase and 5-phase method which uses BSDF into the simulation. And I found people say the 3/5 phase method with BSDF is more accurate for daylight simulation.
I would like to know more about what are the essential steps to take care of using the 3-phase and 5-phase method. Also, I want to know how to use a BSDF material file? or how I can get or make one?
