FTE Requirement/Calculation for storage facility

If there is anyone out there that can answer this, I'd appreciate it. My client is getting antsy. Does this seem like a CIR or does anyone know of precedent for counting average occupancy for "regular occupancy"? The facility will need to be deigned to meet occupied standards, we are trying to see how much float we can put on things like temperature and how to control ventilation, but as an indoor facility it will need to meet ventilation and comfort requirements.

Thank you Tristan, that was my read as well. As far as the definition of regularly occupied, do you see (or have you seen) any wiggle room? If the spaces are designed for regular (or at least during a wide range of times, say 6AM to 11PM) occupancy for any user to enter and interact in the facility, wouldn't there be a case to be made that the design is for an occupied building? These are going to be conditioned spaces with some sort of ventilation controls and code may treat it as an occupied space... Thanks for the reply.
