Conditioned Floor Area is not calculated the same as Building or Zoning Code Floor Area.
Conditioned Floor Area (CFA) is the total floor area (in square feet) of enclosed conditioned space on all floors of a building, as measured at the floor level of the EXTERIOR surfaces of exterior walls enclosing the conditioned space.
CFA is calculated from the plan dimensions of the building including the floor area of all conditioned and indirectly conditioned space on all floors. It includes lofts and mezzanines but does not include covered walkways, open roofed-over areas, porches, pipe trenches, exterior terraces or steps, chimneys, roof overhangs or parking garages. Unheated basements or closets for central gas forced air furnaces are also not included unless shown to be indirectly conditioned.
