Abstract

An energy service business system includes a database which stores past data about an energy consumption of a facility before taking energy-saving measures, a measurer which measures present data of the energy consumption after taking the energy-saving measures, and a calculator which calculates energy curtailment quantities facility before and after taking the energy-saving measures. The past data in the database are stored in a form correlated with data of a production quantity, and the measurer measures the present data of the energy consumption together with data of the production quantity after taking the energy-saving measures. The calculator retrieves the past data having production quantity data within a set allowable range corresponding to the measured present data having production quantity data, and calculates the energy curtailment quantities by comparing the retrieved past data having production quantity data and the measured present data having the production quantity data.

Claims

1. An energy service business system comprising:

a database which stores past data about an energy consumption of at least one of a production facility and an utility facility utilizing cold or warm heat energy before taking energy-saving measures by installing energy-saving equipment;

measuring means which measures present data of the energy consumption of the at least one of the production facility and the utility facility after taking the energy-saving measures; and

calculating means which calculates energy curtailment quantities of the at least one of the production facility and the utility facility before and after taking the energy-saving measures by installing the energy-saving equipment;

wherein the past data in the database are stored in a form correlated with data of a production quantity of the production facility before taking the energy-saving measures;

wherein the measuring means measures the present data of the energy consumption of the at least one of the production facility and the utility facility after taking the energy-saving measures together with data of the production quantity; and

the calculating means retrieves the past data having production quantity data within a set allowable range corresponding to the measured present data having production quantity data for the at least one of the production facility and the utility facility, and calculates the energy curtailment quantities by comparing the retrieved past data having production quantity data and the measured present data having the production quantity data.

2. An energy service business system according to claim 1, wherein the calculating means retrieves a plurality of the past data corresponding to a plurality of production quantities approximating the measured production quantity, performs calculations for estimating past data corresponding to the measured production quantity from the plurality of past data, and calculates the energy curtailment quantities by comparing the thus calculated past estimated data and the present data.
