Tracking the sun's reflection off of glass

[Nick_E]

Hi All,

 

I am trying to track the light from the sun after it is reflected off of a glass skylight. I would like to link the sun’s reflected beam to a daylight system so that when I change the date or time it will show where it hits the surrounding existing buildings. I have attached a simplified model which shows the sun, the glass and an existing building. How would I go about doing this?

 

Thanks in advance for you help,
