A method for adjusting a plurality of controlled subsystems in a building or plant that facilitates cooperative energy usage with a utility provider. By referring to a single profile of adjustments that correspond to changes in the value of a utility signal and distributing this to each relevant controller for each subsystem, a single setback delta can be applied to each subsystem for each change in utility signal value (i.e., pricing information). Alternatively, multiple profiles can be used to provide for firmer control and thereby allow for different zones to respond differently to a single change signal sent by the utility provider.

A controller for an environmental control system, wherein the controller accesses one or more setpoints and controls the environmental control system such that one or more environmental conditions of an inside space of a user's facility/home/building are maintained in accordance with the one or more setpoints, the environmental control system further receiving one or more energy price related signals from a utility, the controller comprising:a communications unit adapted to receive one or more offset commands from a location that is remote from the user's facility/home/building, the one or more offset commands providing one or more setpoint offsets, each corresponding to a energy price related signal; and a controller for receiving the one or more setpoint offsets, and for calculating one or more setpoints for the environmental control system using the one or more setpoint offsets and the one or more energy price related signals provided by the utility. 16. A controller according to claim 15 wherein the controller selects the one or more setpoint offsets that correspond to the energy price related signal received from the utility.17. A method for controlling an environmental control system for a user's facility/home/building, the method comprising the steps of:storing one or more setpoint indicators at a location that is remote and separate from the user's facility/home/building, establishing communications with the environmental control system and providing at least selected setpoint indicators to the environmental control system; and operating the environmental control system to control one or more environmental conditions of an inside space of the user's facility/home/building in accordance with one or more setpoints, wherein the one or more setpoints are based on the selected setpoint indicators. 18. A method according to claim 17 wherein the one or more setpoint indicators are actual setpoints.19. A method according to claim 17 wherein the one or more setpoint indicators are setpoint offsets.20. A method according to claim 17 wherein the one or more setpoint indicators include both actual setpoints and setpoint offsets.21. A method according to claim 17 wherein the one or more setpoint indicators are stored in a database.22.
