Net Square Meter or Net Square Foot
The sum of all "assignable" areas.
"Assignable" refers to all areas on all floors of a building assigned to, or available for assignment to, an occupant or specific use. The area taken to the inside face of the external walls of a building but excluding the area of cores and corridors and loss factor. The loss factor is a sum of other “non-usable” spaces, such as thickness of an exterior wall, interior walls, wet walls, chases, trash chutes, mechanical space. The loss factor is a user assumption for what percentage of the floor area not to be counted or considered "lost" out of the "assignable" area.
Formula:
Net sq m or NSF = (Gross Floor Area - Core and Corridor area) x (1 - Loss Factor %)
