Floor Service Areas on a floor without an occupant METHOD B

Measuring a 13 story office building using METHOD B. The second floor of the building has no occupant areas. A fitness area, and a few conference rooms are Building Amenity Areas. From a previous question someone asked on December 3, 2014, I've learned that there is no Base Building Circulation on a floor without occupants. The central core of the building has the typical MVP's for elevators and stairs. My question is what about typical floor service areas, like a data room, or electrical room, or washrooms? Where on other floors they are Floor Service Area, and would be proportionately shared among the tenants of that floor, this floor has no tenants. Would they be Building Service Area in this case?

Also would the corridors on this floor without tenants be Building Service Area, Floor Service Area, or Building Amenity area?

Hi Blair,

In Method B, Floor Service Area isn't allocated to Occupants on the same floor directly like it is in Method A. Instead, all common areas (Base Building Circulation, Service & Amenity Areas) are pooled together to come up with a single load factor. Building Service Area and Floor Service and Amenity Areas are essentially the same thing since they are a remainder in the Service and Amenity Areas Column (column J) after Occupant Area and Base Building Circulation are deducted from the Preliminary Floor Area. Therefore, it doesn't really matter how you allocate your corridors. You can designate the corridors as Building Service Area, but they are really "Service & Amenity Areas" from a calculation perspective.
