Classification: CPC G  H  Y | IPC G  H

Claim 7:
8. A building manager comprising:
a communications interface configured to receive time-of-use information from a smart energy grid; and
a processing circuit configured to receive inputs from a plurality of building subsystems or devices and provide outputs to the plurality of building subsystems or devices, the processing circuit providing a plurality of control algorithm modules configured to process the inputs and to determine the outputs, wherein the plurality of building subsystems or devices comprise an electric vehicle charging system operable to charge plug-in hybrid or electric vehicles (PHEVs);
wherein the processing circuit is configured to process the time-of-use information received from the smart energy grid using tiering information or prioritization information for the plurality of building subsystems or devices to generate tiered or prioritized load shedding decisions for the plurality of building subsystems or devices such that the time-of-use information affects a high priority group of the building subsystems or devices less than the time-of-use information affects a lower priority group of the building subsystems or devices wherein generating the load shedding decisions comprises determining one or more times at which to charge the PHEVs, allow charging of the PHEVs, suspend charging of the PHEVs, or restrict charging of the PHEVs;
wherein the processing circuit is configured to use the load shedding decisions to generate control signals for the plurality of building subsystems or devices and provide the control signals as the outputs to the plurality of building subsystems or devices.
