NC-2009 EAp2: Minimum Energy Performance
I remember reading it somewhere that exhaust fan that is not interlocked the the HVAC should be process energy (room exhaust). I wonder if anyone could point me to the source of it or if it's true or not for LEED. 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.

These last two answeres should be codified! Fantastic summary.
