METHOD FOR RECOVERING ENERGY SAVING FACILITY COST AND SYSTEM FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To reduce the increase of initial costs at the time of introducing an energy saving facility, and to realize its application even when the scale or energy saving effect of the introduced facility is relatively small. SOLUTION: The reduced sum of running costs in a fixed period is predicted based on the prediction of the facility operation of a user being the target to which an energy saving facility is sold, and the calculated reduced sum is used to decide the initial costs. Also, the actual operation of a sold energy saving facility 8 is remote-controlledly monitored, and stored through a server 6 in a history data base 7. The reduced sum of the running costs in the fixed period is periodically calculated by a business provider terminal 1 based on the actual operation, and stored in a data base 2. Also, the charge based on the reduced sum is periodically communicated through an Internet 3 to consumer terminals 4a and 4b or financial institute terminals 5a and 5b, and drawn from the account of the user, and the reduced sum of the running costs is periodically collected from the user.
