We have a small mechanical equipment room that contains a backup diesel generator. It is being ventilated to remove exhaust and excess heat. However, ventilation rates do not meet those required per ASHRAE 62.1-2007 for an 'electrical equipment room' which seems like the closest possible space category in ASHRAE 62.1. It is unclear to me whether this is the appropriate classification, as our understanding is this classification is intended to apply to rooms with transformers and other purely electrical equipment. If not, is there a more appropriate category of space, or should we just the space to meet engineering and code requirements and not worry about ASHRAE 62.1 for that particular space?

Michael,
I agree with your interpretation of what the 'electrical equipment room' classification is intended to apply to, and I would not use that classification for this space. In fact, I would say that this type of space is outside of the scope of ASHRAE 62.1-2007, as this space is likely not intended for human occupancy. However, this does not mean that it shouldn't be exhausted, you would just need to demonstrate compliance with the applicable code requirement.
