Abstract

PURPOSE: To effectively and efficiently melt snow by a method wherein air taken in a building is warmed by geothermal, warm air flows out from the vent opening of an inner roof material through a garret and is discharged through a space between inner and outer roof materials. CONSTITUTION: Outside air taken in through an outside air inlet 8 is warmed in a space in an underfloor 10 by geothermy through an outside air vent passage 7 running between an outer wall surface 7A and a heat insulation material 7B. The warm air is raised in an inside air vent passage 9 and reaches a garret with the warm air heat-exchanged with heat energy, generated by an indoor heating apparatus 13, through an inside air vent passage 9. Warm air flows out through a vent opening 3 of the apex of a protrusion part 1A of an inner roof material 1 of a corrugated folded plate structure where a heat insulation material is stuck on an inner surface and discharged from a drain port 6 through a flow passage 5 between outer and inner roof materials 4 and 1 formed of a crest-form stainless steel sheet to melt snow cover 18. Further, a heat storage tank 16 may be arranged in an underground if necessary.
