Hello i am currently conducting an annual daylight analysis , i am configuring with the glass modifier and glass material. i found that there are 2 transmittance value input are they the same or are they different thing.
Simple answer is, modifiers are for Radiance (daylight) simulations while materials are parts of constructions for OSM/E+ (thermal) simulations.
I would not use any materals/constructions if you only want to do daylight analysis
