Abstract

A method and system for improved energy utilization within a building or facility. The building or facility includes one or more systems each controlling one or more energy consuming devices initially operated with a normal energy consumption. The method includes receiving notification of an energy event requiring a reduction of energy consumption within the building or facility, determining an occupancy of one or more areas of the building or facility using at least one of the one or more energy consuming devices, initiating an energy reduction mode upon receipt of the notification of an energy event, and terminating the energy reduction mode at the conclusion of the energy event. The energy reduction mode initiation includes sending a first communication to at least one of the one or more systems requesting the respective systems to operate one or more of the energy consuming devices with a reduced energy consumption during the energy reduction mode. The first communication includes the determined occupancy of the one or more areas of the building or facility. The energy reduction mode termination includes sending a second communication to at least one of the one or more systems requesting the respective systems to operate one or more of the energy consuming devices with the normal energy consumption at the conclusion of the energy event.
