I did this one super-fast so, I'm sure there are a few things I'm missing, i.e., the Drafting Room may be underlit...
Please, let me know if you see any errors.

Rigid duct illegally crosses joists east of the riser shaft. Fatal.
Rotate 2x4 lights in the architect's office for more uniform coverage.
Studio is under lit.
Wasted rigid duct in the architect's office and supply closet.

Thanks Sparky83! (I think I needed to get those mistakes out of my "system")
