A technology for achieving energy saving by efficiently controlling each of a plurality of equipment systems is proposed. The equipment control system includes an air conditioner system, a refrigerator system, a refrigerator/freezer showcase system and a central coordinator. Status data related to electric equipment provided in the systems is transmitted to the central coordinator. The central coordinator computes control data for the systems, based on the status data of the electric equipment transmitted. The central coordinator is provided with the function of computing the control data, based only on the status data of the corresponding electric equipment and the function of computing the control data, allowing for the status data of another of electric equipment in addition to the status data of the corresponding electric equipment.
