Abstract
A system for utility base lining records historic values of utility loads for regions within a facility. The system also records historic values of independent variables such as outside temperature, time, date, workday versus non-workday, and occupancy. A similar data selector seeks out similar times in the past and submits the data from those times to a base line estimator which produces a baseline estimate. Differences between the current load and the estimated load can trigger alarms or investigations to determine why the utility load has changed. False alarms can occur when the utility load drifts over time. Detecting drift can help reduce false alarms or help in the investigation of alarms. A graphical user interface (GUI) can present an easily understood representation of the regions, load estimation errors, alarms, and detected drift.
