1. A computerized building management system comprising:

  • a communications interface configured to receive information from a smart energy grid;

    a processing circuit;

    non-transient computer-readable media in communication with the processing circuit;

    an integrated control layer configured to receive inputs from and to provide outputs to a plurality of building subsystems, the integrated control layer including a plurality of control algorithm modules configured to process the inputs and to determine the outputs;

    a fault detection and diagnostics layer configured to use the inputs received from the integrated control layer to detect and diagnose faults;

    a demand response layer configured to process the information received from the smart energy grid to determine adjustments to the plurality of control algorithms of the integrated control layer;

    wherein the integrated control layer, the fault detection and diagnostics layer, and the demand response layer are each computer code modules stored in the non-transient computer-readable media, wherein the computer code modules configure the processing circuit, when the modules are executed by the processing circuit, to provide the actions of the integrated control layer, the fault detection and diagnostics layer, and the demand response layer;

    wherein the smart energy grid comprises at least one of;

    (a) a smart meter configured to receive time-of-use pricing information and wherein the information received by the communications interface is the time-of-use pricing information, and (b) energy providers and purchasers configured to provide daily or hourly time-of-use pricing information to the communications interface;

    wherein the demand response layer is configured to curtail energy use of the plurality of building subsystems based on the time-of-use pricing information;

    wherein processing the information by the demand response layer and received from the smart energy grid comprises comparing pricing information to threshold information associated with adjustments for the plurality of control algorithms.
