Solar and visual absorptance for EP simulation

Hello guys,

I run a simulation with rammed earth, so I define my own materials with EPOpaqueMat component and when I change the solar absorptance and visual absorptance coefficients because I’d like to see the impact of reflectance I don’t see any change in the operative Temperature. Is that right or I have to change also the thermal absorptance? I am looking forward to hearing from you.

Thank you in advance!
