Calculation packs

When determining the population of a building, Realistic Population 2 does two sets of calculations:

1. The physical size of the building's model is used to to calculate the building's floorspace.
2. This floorspace is then used to assign a population (households, workplaces, or students).

The calculations used for each of those steps (floorspace and population) are determined by calculation packs, which are collections of values that tell Realistic Population 2 how to calculate these figures. Floorspace calculations are performed by floor calculation packs, and population calculations (based on that floorspace) are performed by population calculation packs

Realistic Population 2 comes with a number of inbuilt calculation packs. Additional calculation packs can be created and edited through the mod's options panel. The default calculation pack for each service type can also be set in the options panel, and specific calculation packs can also be assigned to each different building asset through the building settings editor.

In addition to the new-style calculation packs, a Legacy option is also available. This option enables calculations according to the method used by Whitefang Greytail's original Realistic Population and Consumption mod and versions 1.x of Realistic Population Revisited.

A calculation pack can only be applied to one particular service (Residential/Industrial/Commercial/Office/School), due to the different nature of these services. This means that if you create a calculation pack for, say, Commercial, you won't be able to apply it to your factories (and vice-versa). However, you can easily use the options panel to create a duplicate of an existing pack and change the service (so although you do need to create another pack, you won't need to re-enter all your figures).

For clarity, this document (and the mod generally) use the American style of floor counting, commencing with the first floor (where British English 'ground floor' is equal to American 'first floor').
