In the world of architecture, space planning, leasing and UniSpace, we use many area types as metrics.
Here are a few of our “areas” that measure our buildings.
UFA – usable floor area – The sum of the floor areas measured at floor level from the general inside face of walls of all interior spaces related to the primary function of the building. (Excluded: lobbies, fire escapes, verandahs, balconies, corridors, passages, toilet, rest rooms areas, cloak, locker areas, cleaner’s rooms, mechanical plant and equipment rooms, electrical equipment and switchrooms, tank rooms, lift motor rooms, meter cupboards, telecommunication switchrooms, refuse collection areas, loading bays and all car parks.
Note UniSpace ‘measure’ all University space in UFA for reporting and consistency (including the ‘excluded’ types)
NLA – The net lettable area of a building is the sum of its whole floor lettable areas. The whole floor net lettable area is calculated by: Taking measurements form the internal finished surfaces of permanent internal walls and the internal finished surfaces of dominant portions of the permanent outer buildings walls. (Excluded: Stairs, acessways, fire stairs, toilets, recessed doorways, cupboards, telecommunications cupboard, fire hose reel cupboards, lift shafts, escalators, smoke lobbies, plant / motor rooms and tea rooms and other service areas where all are provided as standard facilities in the building).
GFA – Gross Floor Area – The sum of all areas as per the Fully Enclosed Covered Area, but in this case measured to the outside face of the enclosing walls.
GBA – Gross Building Area – The total enclosed and unenclosed area of the building at all building floor levels measured between the normal OUTSIDE face of any enclosing walls, balustrades and supports.
FECA – Fully Enclosed Covered Area – The sum of all such areas at all building floor levels, including basements, floored roof spaces and attics, garages, penthouses, enclosed porches and attached enclosed covered ways alongside buildings, equipment rooms, lift shafts, vertical ducts, staircases and any other fully enclosed spaces and usable areas of the building.
UCA – Unenclosed covered area – The sum of all such areas at all building floor levels, including roofed balconies, open verandahs, porches and porticos, attached open covered ways alongside buildings, undercrofts and usable space under buildings, unenclosed access galleries (including ground floor) and any other trafficable covered areas of the building which are not totally enclosed by full height walls.
