Abstract

An energy saving system acquires seat occupation information from a database of a seat occupation management system, detects equipment appliances of the places at which personnel are not seated, on the basis of the seat occupation information and transmits control information based on the detection result to an equipment control system so that unnecessary equipment appliances of the places where the personnel do not exist can be turned off. The energy saving linking system executes a processing for calculating optimal position and range in accordance with the seat occupation information, calculates an area providing the highest movement efficiency to overtime personnel and displays the calculation result.

Claims

1. An energy saving system comprising:

an equipment control system having means capable of executing control for equipment appliances inclusive of air conditioning equipment or illumination equipment through a network;

a seat occupation management system for specifying physical arrangement positions of terminals connected to network appliances on the basis of connection information to said network appliances and managing at which seat of which floor of an office a personnel using said terminal is seated; and

a server capable of being connected to both of said systems through the network,

wherein said server further includes means for acquiring operation information of said equipment appliances managed by said equipment control system, means for collating and analyzing the information acquired and means for transmitting the information analyzed to said equipment control system; and

wherein said energy saving system controls said equipment appliances on the basis of seat occupation information managed by said seat occupation management system.

2. The energy saving system according to claim 1, further comprising:

means for analyzing a seat occupation distribution at a certain point of time on the basis of the seat occupation information acquired from said seat occupation management system,

means for calculating a seat area providing high movement efficiency to the seat occupying personnel, and

means capable of displaying the calculation result.

3. The energy saving system according to claim 2 further comprising:

information terminals such as personal computers capable of being managed by said seat occupation management system and receiving a message and displaying a reception content through the network, and

means for comparing seat occupation information acquired from said seat occupation management system with the area information acquired, and judging whether or not the position of said information terminal is within said area and reporting a message corresponding to the judgment result to said server.
