PURPOSE: To reduce costs by a method wherein when a building is constructed, a hollow foundation pile is driven into the ground and at the same time heating medium is injected into the foundation pile using a heating medium injecting, extracting means or the heating medium is extracted from within the foundation pile. CONSTITUTION: Heating medium is injected from an air conditioner 6 into the hollow section 5 of a foundation pile 4 through a heating medium pipe 7a, while the heating medium is extracted from within the section 5 through a heating medium pipe 7b. Next, at this moment, heat of the heating medium stored in the section 5 is stored in the soil of great volume in the underground through all seasons for a long period of time. And as heating medium, air or other gas, or water or other liquid is used. And, if required, inner pipes, partition walls, or heat transfer tubes are inserted into the section 5 to form a heating medium passage. Further a means for accelerating heat transfer between heating medium, inner and outer walls of pile, underground, a heat collecting circuit, a temperature measuring unit, a flow regulating unit are provided. Thus, embedding of heat transfer tubes is not needed and heat can be stored for a long period of time.
