"X" Tool: Capacity Calculations and Floorage
« on: September 06, 2007, 09:37:41 AM »
The capacity for RCI buildings is based on the volume of the building.

The Volume is calculated from the properties Occupant Size (Width, Height and Depth) and the Filling Degree:
      Volume = Width Depth Height Filling Degree

The Floorage of a building is caculated from the Volume by dividing with the floor height, 3 m:
      Floorage = Volume / 3

The Capacity is calculated by dividing the total floorage by the Floorage Requirement for each inhabitant/worker:
      Capacity = Constant + Floorage / Floorage Requirement

The Constant is 2 for industrial buildings and 3 for residental and commercial buildings.

The Floorage Requirements (per person) are listed in the table below:

Hi
Just a small correction (?)
I believe the floor height that X-PIM is using is actually 3 m.
I was looking through .xml with definitions (dated 2009-11-05) and found out that usually the formula for R&C is:
Capacity =  round( 3 + BiasedVol/(3*floorage_req))
where BiasedVol is Volume*min(1,0.51+(Volume/26000.0)**2)
It seems that Volume used for Capacity calculations is corrected downwards if it's lower than 18200 m3 (don't know why :))
Regards
G.

Quite correct! :thumbsup:
The post above was partly based on information we had before introducing the filling degree (which is 0.50 by default).

I've corrected the post now. Thanks! :)

To ensure that small buildings get small enough capacities to become growth stage 1... :)

I use PIM to do a Landmark building functional and then using SC4 Tool correcting her capacities. Is it possible to make a CO building
- 80 000
- 100 000
- 1 million
jobs. I tried several times but did not receive - why?
