Abstract: A system for managing energy use of buildings and the like uses predicted meteorological data, for example from weather forecasts, applied to models of the energy systems of the building to predict future energy use and costs. This predicted information is used to produce automatic alerts allowing future energy use to guide current changes to reduce energy.

Abstract: An electric power usage and reporting system for collecting electric power demand readings from multiple properties which may be either commonly owned or leased by the same company, processing the demand data to generate KWH and KW information on an individual property basis and on a combined properties basis and generating a report including the KWH usage and KW demand information. The report includes information on electric power KWH usage and KW demand in the aggregate and with respect to each property and includes information on coincident KW demand in the aggregate and with respect to each property.
