Toilet Exhaust

Dear all,

I would like to double check with you if I'm modeling my toilet exhaust
correctly, in order to answer the USGBC's design review comments
properly!

* The project has exhaust fans on the roof, with ducts to each
toilet (i.e., ducted exhaust).

* Since the toilets are not conditioned, I'm placing them
arbitrarily under random AHUs.

* I am then entering the exhaust flow rate and the kW per flow as
in the attached screenshot.

1. Can someone please confirm that the above is correct?

2. I assume ASHRAE 90.1 App G3.1.2.9 (baseline fan power
corrections) applies for toilet exhausts. I think I'll have to use the
correction factors for the

"Fully ducted return and/or exhaust air systems" (125 Pa). I'll
plug in the resultant kW/cfm in the input box in the attached drawing.
Correct?

Many thanks,

Omar
