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.
