Fume hood exhaust fan process load?

I think fume hood exhaust are unregulated in 90.1 2007 thus should be process load. But just want to confirm. I do see EPAct 2005 says fume hood should not be treated as process load...

They are a process load.

Thanks Marcus. I have an another question hope you can help. We have a main AHU serving both lab and other spaces in the proposed case. In the baseline, since Lab needs to be separated from the rest of the spaces due to higher load, can we still claim the fan power pressure drop adjustment for the system serving the non lab spaces? In our design, since those non-lab spaces is served by the same system.

Maybe. Which exception to G3.1.1 are you applying? What pressure drop adjustment are you claiming?
