摘要

PROBLEM TO BE SOLVED: To allow a building operator that is a customer to safely use an energy-saving service for reducing the operation cost (energy cost) by an energy- saving work so that the cost of the work can be donated from the reduced amount of the operation cost. SOLUTION: A part of the amount of divided payment collected from the building operator as an equivalent for the energy-saving service is reserved on the building operator side. When the energy-saving quantity for a fixed period in a building facility is less than a reduction guarantee quantity, the amount corresponding to the deficiency is canceled by the accumulated amount from the amount of divided payment. When the energy-saving quantity is less than the reduction guarantee quantity and the amount corresponding to the deficiency is larger than the amount of savings from the amount of payment by installation, the energy-saving service provider guarantees to pay the deficiency.
