Abstract

Systems and methods for enterprise energy automation are provided. An enterprise energy automation system determines an energy performance model for each of a plurality of building automation systems using data extracted from the plurality of building automation systems. The performance models for each of the plurality of building automation systems are used in conjunction with pricing information received from an energy supply and delivery system to determine an optimum operating strategy for the plurality of building automation systems.
