Given the definition as follows:
FIRE AREA. The aggregate floor area enclosed and bounded by fire walls, fire barriers, exterior walls or horizontal assemblies of a building. Areas of the building not provided with surrounding walls shall be included in the fire area if such areas are included within the horizontal projection of the roof or floor next above.
When calculating fire area for a building with non-fire-resistance rated exterior walls, is the fire area measured from the exterior face-of-wall, or to the interior face-of-wall?
Where exterior walls are of fire-resistance rated construction, is it appropriate to measure to the interior face-of-wall?
