PURPOSE: A natural energy utilization method using geothermal heat, convection difference, and air circulation is provided to execute the air circulation by installing an inside air exhaust pipe, a geothermal intake pipe, and an outside air intake chamber. CONSTITUTION: An inside air exhaust pipe(71), a geothermal intake pipe(90), and an outside air intake chamber(10) are installed to execute a natural energy utilization method using geothermal heat, convection difference, and air circulation. The inside air exhaust pipe is installed on a building to utilize the convection difference. The geothermal intake pipe is installed in the underground of the building to absorb the geothermal heat. The outside air intake chamber is installed on the ground so that the outside air is flowed in. An inside air circulation passage and an outside air circulation passage are installed in the building. An opening/closing controller(22) is opened in the inside air exhaust pipe and the outside air intake chamber. The inside air is exhausted to the inside air exhaust pipe after moving up by the convection difference. The geothermal heat of the geothermal intake pipe is flowed into the indoor. The air circulation of the inside air and the outside air is executed due to the convection difference ascending current flowed from the outside air intake chamber to the geothermal intake pipe.
