Abstract

A system for remote energy consumption system identification of a facility includes a processor, and a memory coupled to the processor. The system also includes an energy consumption database accessible by the processor. The energy consumption database includes aggregated energy consumption data associated with the facility. The system also includes a facility database accessible by the processor. The facility database includes facility data associated with the facility. The system further includes an external variable database accessible by the processor. The external variable database includes external variable data corresponding to the energy consumption data. The system also includes an analysis engine residing in the memory and executable by the processor. The analysis engine is operable to generate disaggregated energy consumption data using the aggregated energy consumption data, the facility data, and the external variable data, and identify an energy consumption system of the facility using the disaggregated energy consumption data.
