ENERGY MANAGEMENT

PROBLEM TO BE SOLVED: To provide an energy management system using various communication methods and protocols which communicate with an energy using apparatus and control an operational mode of the same. SOLUTION: An energy management module 100 for an energy consuming apparatus 120 is mounted on the energy management system 200. The module 100 includes a module main controller to mount a computer processor which communicates with a computer readable storage medium storing a computer executable code. When the computer executable code is executed by the computer processor, the code executes a method including a step which judges whether a demand state is a peak one or not and a step which utilizes a reduced operational mode of the energy consuming apparatus during the peak demand state and utilizes a normal operational mode of the energy consuming apparatus during a demand state other than the peak demand state. The system 200 is allowed to mount a system main controller 201 further. COPYRIGHT: (C)2010,JPO&INPIT
