Calculation Modifiers
A calculation modifier is a formula that you can apply to a space to change
the calculated results of its associated area or perimeter values. Calculation
modifiers can also be applied to a zone to change the calculated results of all
spaces attached to that zone. You might want to change calculated results for
number of purposes; for example, to account for plaster deductions or the
tiling in a bathroom.
By default, a calculation modifier is applied only to the base area and base
perimeter of the space. To apply the modifier to the net, usable, and gross
boundaries of a space, you need to create and apply a property set definition
that contains properties for the calculated area and perimeter values of the
those boundaries. For more information, see Property Set Definitions on page
3785.
Calculation modifiers work cumulatively. When you apply several different
modifiers to a space or a zone, they are all applied. Therefore, it is important
to define the order in which they are used.
Example: You have a space area of 25 square meters. You want to apply 2
different calculation modifiers to it. Calculation modifier A deducts a value
of 0.3 square meters for a column. Calculation modifier B divides the space
by 2 (in some international calculation schemes, this is used for calculating
balconies).
â– If you apply the plaster deduction first and the division second, you get
the following result:
Calculation Modifier A: 25 m

- 0.3 m

= 24.7 m

Calculation Modifier B: 24.7 m

/ 2 = 12.35 m
