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.
