Shading analysis glass element

Hello,
I would like to conduct a shading analysis and compare a concrete wall with a concrete wall with glass elements as the shading elements. Glass is not fully translucent. How can I take this into account in the simulation? Which elements should I use?
Thank you in advance for your help. Best regards
