A structure utilizing geothermal energy capable of effectively utilizing a thermal energy in an underground constant temperature layer while using a supplementary heater and an air conditioner and natural energies such as solar heat or solar light, wind power, and water power in order to prevent limited fossil energies such as petroleum, gases, and coal from being exhausted, wherein an insulating wall (A) formed of a plurality of insulation panels (1) connected to each other and extending from a ground surface (4) to the underground constant temperature layer (21) is buried in the ground while surrounding a building (22) adhesively to the ground exposed portion and the underground buried portion of a foundation (5).
A structure utilizing geothermal energy comprising an insulating wall buried in the ground while surrounding a foundation of a building, wherein said insulating wall extends down to a depth deeper than said building foundation integrally and continuously from the outer wall of the building so far as to reach the depth of an underground constant temperature layer, said insulating wall is buried at a location spaced from the outer side face of said building foundation, and said insulating wall is formed by a plurality of insulation panels made of a synthetic resin.
