Green Roof in Daylight Simulation?

this is a very helpful discussion but kindly I would like to ask a question to get more information!
If I am using ladybug and honeybee for green facades and I want to see the daylight inside the space how will be reduced as daylight not thermal so How can I add the material of greenery on the facade??
1)Should I create a double facade? I mean one for glass fo example and a panel to put material of greenery?? How to set material?
2) which type of simulation you recommend to use the radiation inside space or the illuminance one ? If you could send any example it will be very helpful

Hope to have answer first of all of how to put green facade materials and did anyone try it?

Thank you so much all for any help
