Abstract:
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 a 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 and utility facility after taking the energy-saving measures; and calculating means which calculates energy curtailment quantities of the at least one of the production and utility facility before and after taking the energy-saving measures by installing the energy-saving equipment; wherein said past data in said database are stored in a form correlated with data of temperature and humidity of atmosphere as a variable characteristic of the energy consumption of the at least one of the production and utility facility before taking the energy-saving measures; wherein said measuring means measures said present data of the energy consumption of the at least one of the production and utility facility after taking the energy-saving measures together with temperature and humidity data; and wherein said calculating means retrieves said past data having temperature and humidity data within a set allowable range corresponding to said measured present data having the temperature and humidity data for the at least one of the production and utility facility, and calculates the energy curtailment quantities by comparing said retrieved past data having temperature and humidity data and said measured present data having the temperature and humidity data.
