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.

Probes of a conductor length measurement device are connected to piping, and an output voltage is applied to the piping through the probes. A frequency spectrum curve is subsequently calculated by subjecting a voltage signal to FFT. Resonant frequencies of the piping are then determined from this frequency spectrum curve, and the total length of the piping is calculated on the basis of the resonant frequencies. The total length of the piping can therefore be easily measured without the need to install, for example, any measurement instruments at branch terminals.
