Collection method of and collection system for collecting costs of energy-saving facilities
First Claim
1. A system for collecting the costs of an energy-saving facility installed to a customer, comprising:
- means for storing a predicted reduced amount of running cost of the energy-saving facilities for a predetermined period, the reduced amount calculated based on a prediction of operation of a customer;
means for monitoring an actual operational status of the energy-saving facilities;
means for calculating a reduced amount of the running cost on the basis of an actual operational status of the energy-saving facilities, the status is obtained from the remote monitoring part; and
means for collecting from the customer an amount to repay the reduced amount of the running cost which has been subtracted from the initial cost of the energy-saving facility.

Abstract
A collection method and system which restrains an increase in initial cost of energy-saving facilities. According to the invention, the reduced amount of running cost of energy-saving facilities for a predetermined period is computed based on a prediction of operation of the facilities, and an initial cost is determined. Actual operation of the energy-saving facilities is monitored, and stored in a history database. Based on the actual operation, the reduced amount of the running cost is periodically calculated and stored in a database. A business enterpriser draws the amount from the customer'"'"'s account corresponding to the reduced amount.
