A method and system for controlling an environmental management system (e.g., an HVAC system) that controls an environmental parameter of a downstream controlled space (e.g., the temperature of a room in a building). The method includes providing a feedback control loop for controlling a controlled environmental parameter (e.g., the supply air temperature), and generating a feedback control signal based on the controlled parameter and a dynamic (e.g., a time constant) of the downstream controlled space. The system includes a device for receiving a signal representative of a measured value of a controlled parameter having a time constant that is smaller than the time constant of the downstream space. The system also comprises a filter, a device for producing a control signal representative of a deviation between a filtered value and a desired value of the controlled parameter, and a device for converting the control signal into a pulsed output signal that turns the device on and off.
