Lighting calculations in Revit

[chimp1]

I was wondering how to perform an outdoor lighting study in Revit. I am familiar with creating a space and developing the average fc for the space.

Can I ask why you need to do it in Revit?

I think Revit does its lighting calculations as an average (likely zonal cavity method). I don't think that would be helpfull for outdoor calculations.
