How to calculate the pool area

The pool area is the abbreviation of * * * belt construction area, that is, the * * * belt construction area owned or used by users. Including elevator shafts, pipe shafts, stairs, garbage pipes, substations, equipment rooms, public halls, corridors, guard rooms, public rooms and management rooms serving the whole building, and public wall areas except the interior of the building. But in general, the pool area of buildings without elevators is 16- 18% of the building area, and that of buildings with elevators is 20-22% of the building area.

The general formula of allocation area algorithm is: allocation area = construction area of each unit × allocation coefficient = * * * total construction area/total construction area of each unit participating in allocation.
