1. A method for controlling power consumption by an HVAC system of a building, comprising:
- using an energy use setpoint as a reference input for a feedback controller;
using a measured energy use as a measured input for the feedback controller; and
using the feedback controller to generate a manipulated variable output for adjusting the operation of an HVAC device.

Abstract
Systems and methods for limiting power consumption by a heating, ventilation, and air conditioning (HVAC) subsystem of a building are shown and described. A feedback controller is used to generate a manipulated variable based on an energy use setpoint and a measured energy use. The manipulated variable may be used for adjusting the operation of an HVAC device.

11. A feedback controller for controlling power consumption by an HVAC system of a building, the controller comprising:
-
a processing circuit configured to generate a value of a manipulated variable for adjusting the operation of an HVAC device, wherein the processing circuit comprises; an error analyzer configured to receive an energy use setpoint as a reference input and to receive a measured energy use as a measured input, wherein the error analyzer is further configured to compare the reference input and the measured input, and to use the comparison to determine an error value; and an error corrector configured to receive the error value and to use the error value to generate the value of the manipulated variable. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
