Is ventilation required for Electrical Switchgear Room?
(OP)
I have a space that houses electrical switchgear. I'm planning on specifying a conventional split system to do the job. I'm wondering if I need to bring in OA by way of a duct (this would increase the cost of the total system). Section 401.3 of IMC 2009 states that ventilation is required during times when the space is occupied. The space won't ever be occupied. Is this essentially stating that I don't need OA? I know that ASHRAE has their own standard practices that encourages the introduction of OA, however, ASHRAE isn't being used by the AHJ.
Any help would be appreciated.
Thanks

Depending on your temperature requirements, could you cool the space just with outdoor air and not the split system? that may be more efficient and would ventilate.
to be sure you can ask the AHJ.
