Patent ID: 8200456

Claim:
A system comprising: a means for defining and identifying a plurality of regions in a facility; a plurality of sensors wherein each sensor produces a load measurement indicating the amount of energy currently consumed in one of the plurality of regions of the facility; a means for determining independent variable values wherein the independent variables comprise outdoor temperature, date, time of day, and regions of the facility; a means for computing a plurality of independent variable measurements indicating the values of the independent variables at different times and for computing a plurality of load measurements indicating values of sensed load measurements at different times; a database storing the load measurements and the plurality of independent variable measurements as historical data; a similar data selector wherein the similar data selector is a Euclidean distance based similar data selector that accepts a recent measurement and produces similar historical data from the historical data, wherein the similar historical data comprises load measurements and independent variable measurements taken when the independent variable measurements were similar to the recent measurement; and a baseline estimation module that accepts the historical load data set and produces at least one baseline estimate for the recent measurement.
