1. A method, operable in a processor, for apportioning energy costs for equipment operation, said method causing said processor to execute the steps comprising:
- receiving, from at least one sub-meter, at least one energy usage and an energy demand corresponding to each of said at least one energy usage during a known period;
receiving, from a master-meter, a total energy usage and a corresponding total energy demand during said known period;
determining a residual energy usage from said total energy usage and said at least one energy usage and a residual energy demand from said total energy demand and said energy demand corresponding to each of said at least one energy usage;
determining a maximum energy demand over said known period, wherein said maximum energy demand is a maximum of an average value of said energy demand corresponding to each of said at least one energy usage determined in each of a plurality of second known periods;
determining a maximum total energy demand over said known period wherein said maximum total energy demand is a maximum of an average value of said received total energy demand determined in each of said plurality of second known periods;
determining a cost of said total energy usage based on at least said total energy usage and said maximum total energy demand;
determining a cost of said residual energy usage based on at least said determined residual energy usage and said maximum residual energy demand;
apportioning said energy costs of equipment operation based on said cost of said total energy usage and said cost of said residual energy usage; and
determining a source of energy generation of said total energy usage and each of said at least one energy usage;
retrieving a greenhouse gas (GHG) emission value associated with the source of generation of said total energy usage and each of said at least one energy usage;
determining an effective emission factor based on the determined sources of energy generation; and
determining the GHG emission based on the effective emission factor.

Abstract
System and methods for appointing energy and environmental costs to provide separate billing statements for operation of business and/or healthcare related equipment is disclosed. The method determining a cost associated with a total amount of energy consumed and a cost for operation of selected equipment with regard to usage and demand. In addition, the greenhouse gas emissions associated with the generation of the energy required to generate the total amount of energy and operate the selected equipment is also determined.
