PROBLEM TO BE SOLVED: To provide a heating and cooling system using underground heat constituted to have an underground heat space on an outer wall side of an underground building to enable heat exchange. SOLUTION: In the heating and cooling system using underground heat, first steel materials 3 are mounted on the outer wall of the underground building 2 positioned in the lower part of a ground building 1, and iron plates 15 are provided astride the first steel materials 3 on ground wall sides of the first steel materials for earth retention. A space of the first steel material 3 between inner wall members 6, 7, 8 provided inside the first steel material 3 and the iron plate 15 is used as the underground heat space 10 for retaining air with underground heat. Second steel materials 4 jointed to the iron plates 15 are embedded around the underground building 2. The air including underground heat absorbed by the steel materials is circulated in a space with the ground building 1 via the underground heat space 10, so as to perform heating and cooling.
