I am designing a development project where I am able to calculate (per NEC) all of the building loads to a tee - except for two retail spaces. The function of the spaces is known (one an 8500 SF restaurant, the other a 3000 SF cigar store), but no part of their HVAC or electrical systems will be designed until well after the service equipment is installed.
I want to be conservative, but not TOO conservative. Give them a reasonably-sized panel that their engineer can work with. My gut (working off very little experience) says 30 w/sf for the restaurant and 25 w/sf for the cigar store (humidors, plus smoking allowed with ventilation required to exhaust up 7 stories to roof). At 208V that would be an 800A service for the restaurant and 200A for the cigars. Is that overkill? If you were selected as the fit-out designer of the spaces would you find it to be sufficient?
If the load goes up any more I'm going to need a second utility transformer - right now trying to fit it all on one. I think I'm good but any thoughts are appreciated.
