ENERGY SETTING DEVICE, ENERGY SETTING METHOD, AND RECORDING MEDIUM

A reduction instruction receiver receives a reduction instruction for energy from a server. An energy setter sets, when the reduction instruction receiver receives the reduction instruction, individual target energies for the respective subsystems, the individual target energies each being a target value of a consumption energy for a corresponding subsystem such that (i) a total of individual target energies that are target values of consumption energies for the respective subsystems is smaller than a total target energy that is a target value of a consumption energy of an entirety of the subsystems, and (ii) a higher correlation among consumption energies of the respective subsystems provides an increase in a total margin energy, the total margin energy being a difference between the total target energy and the sum of the individual target energies. The control-instruction transmitter transmits control-instruction information for control of the facility device based on the set individual target energies.
