Patent ID: 8819018

Claim:
A process comprising: generating an electric power consumption signature database by: receiving into a computer processor data from an electric power consumption measuring meter and auxiliary data from a building management system; and clustering the data; wherein the meter is positioned at a measurement point in a building; the data relates to aggregate electric power consumption of a plurality of electric power consuming devices in the building; and the electric power consumption signature database comprises a steady-state load classification component and a transient shape component; after the generation of the electric power consumption signature database: receiving into the computer processor additional data from the electric power consumption measuring meter and the auxiliary data from the building management system; processing the additional data to generate a second steady-state load classification component; extracting a second transient shape component from the additional data; and combining the steady-state load classification components and the transient shape components from the electric power consumption signature database, the second steady state load classification component, the second transient shape component, and control signals and status signals associated with the plurality of electric power consuming devices; wherein the combining comprises: a summation or a product of the steady-state load classification components and the second steady state load classification component; a summation or a product of the transient shape components and the second transient shape component; a summation or a product of the control signals; and a summation or a product of the status signals.
