I remember seeing from somewhere that if the exhaust fan is not interlocked with the HVAC, it should be considered a process load and modeled the same in proposed and baseline. Could someone point me the source of this or if this is applicable to EAp2. Thanks

I don't think there is anything to point to on this issue. A fan is process if it is not directly regulated by 90.1. So I can't point you to something that does not exist.
Fans serving unconditioned spaces are process. Fans associated with HVAC systems are not process. An exhaust fan within a conditioned space that is not interlocked with the HVAC is process too.
