Showing savings for large process load

I am currently working on a building whose main function will be for painting and which will contain several large paint booths. Over 90% of the energy expended by the building will be to condition the outside air required for the painting process. The intent is to use energy recovery for the paint booth air-conditioning units. ASHRAE 90.1-2007 section 6.5.6.1 Exception c does not require energy recovery for systems that exhaust paint. My intent is to model the baseline building without energy recovery and the proposed with energy recovery and the subsequent process energy savings would be applied toward satisfying EAp2 and earning points for EAc1. Does this sound like a reasonable approach? If not, I would like to hear your suggestions. TIA.
