Answer 6

IPMS 2 = The sum of the areas of each floor level of a Building measured to the Internal. Dominant Face, which may be reported on a Component-by-Component basis for each floor of a Building.

GIA = whole enclosed area of a building within the external walls taking each floor into account and excluding the thickness of the external walls

Question 7

What is the definition of IPMS 3? How is this different from NIA?

Answer 7

IPMS 3 = Usable floor area to the exclusive occupier. 3 elements of IPMS 3; Useable floor area (previously NIA)
· Limited floor area (additional areas that need measuring e.g. balconies/roof terraces/areas with restricted headroom = 3 main differences from NIA, yet do not make up any of the useable floor area)
· Office total (total of limited use area plus useable floor area)

NIA = usable area measured to the internal finish of the perimeter or party walls, ignoring skirting boards, at each floor level. Net internal area covers all of those areas that can be used for a particular purpose.
