1. A cascaded control system for controlling power consumption of a building during a demand limiting period, the system comprising:

  • an energy use setpoint generator configured to use energy pricing data and measurements of a variable condition within the building to generate an energy use setpoint during the demand limiting period; and

    a feedback controller configured to use a difference between the energy use setpoint and a measured energy use to generate a control signal for building equipment that operate to affect the variable condition within the building during the demand limiting period.
