Bill Calculation Scoring Tool

The Scoring Tool uses the same general method as the Home Energy Saver, but has an expanded resource list including wood heating

The basic calculation of energy bills is given in the following equation:

Annual Cost = Annual site energy * utility conversion[resource] * price[resource]

    Where resource is one of electricity ,natural gas ,fuel oil, or lpg

The site units and conversion factors are given in table 1.

When a building is first created default energy prices are assigned based on the state in which their ZIP code is located. The defaults energy prices are presented in table 2 below.
