Questions about BSDF
I understood in a simple way BSDF would be a collection of data “Spectral” (transmission, Reflection - Visible band And solar band) of a certain composition in different angles of observation
Please correct me if I am wrong. the behavior of a solar control glass is varied throughout the day depending on the position of the sun. like the image below

the catalog data that are generated by the manufacturers are laboratory data with standard illuminant of 65 and perpendicular incidence, that is the worst case in terms of performance (higher transmission and less reflection)
my first question is: When I use an annual grid sim with bsdf file in a 3 or 5 phase method, am I considering the actual position of the sun and the actual behavior of the glass in relation to the angle between the two?
if yes, I understand that it is a better approach to assessing light issues.
My second question would be: Based on the understanding that this methodology is effective for light, would it be efficient to determine the annual radiation in this way?
there is some way of accounting for the (dynamic thermal ) behavior of the glass throughout the year, with the objective that this (extra) precision could decrease the thermal load values. instead of establishing shgc fixed and a fixed transmission during the simulation
Are the energy plus and honeybee tools ready to do these calculations?
