Energy service business method and system

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.

Description

CROSS REFERENCE TO RELATED APPLICATION [0001] This application is a continuation-in-part of U.S. application Ser. No. 09 / 843,736, filed Apr. 30, 2001, the contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to energy service business method and system. [0004] 2. Description of the Related Art [0005] There is an increasing interest in the world in global warming and environmental preservation, and efforts for improvement are internationally made. For example, it is demanded to take energy-saving measures to business enterprises of plants and buildings, major energy consumers, to determine energy-saving target values, and achieve such target values within a certain period of time. [0006] Research and development efforts of energy-saving techniques are made in various fields under these circumstances, including, for example, research and development of energy-saving equipment and facili...

Benefits of technology

[0009] Accordingly, it is an object of the present invention to make it easier to apply energy-saving measures.

[0011] A first form of management is characterized in that the investment cost for energy-saving measure is derived from contribution of funds by energy service enterprises and energy conservation effect, i.e., curtailment of the energy costs. More specifically, the process comprises the steps of applying energy-saving measures to object facilities at the cost of an energy service enterprise, measuring the energy consumption after taking energy-saving measures, and calculating the amount of curtailment of the energy costs by comparing the thus measured value with the energy consumption before taking the energy-saving measures previously stored in a database, and allowing the energy service enterprise to receive at least a part of the amount of curtailment. According to this form of management, the customer, not required to make an equipment investment for taking energy-saving measures and plan collection thereof, is easier to introduce energy-saving measures. As a result, introduction of energy-saving measures is encouraged, and inhibition of global warming and preservation of environments are promoted.

Problems solved by technology

If the amount of curtailment of energy costs through energy conservation is smaller than initially expected, furthermore, investment collection would require more years, resulting in a problem of difficulty to adopt measures for achieving a high energy-saving target value.
