PROBLEM TO BE SOLVED: To provide a building with a hot air device capable of assuredly feeding hot air by efficiently using solar energy at a low cost. SOLUTION: This building 2 with a roof comprises a roof 204 and a hot air device 4. The hot air device 4 comprises a solar cell panel 6 provided on the roof 204, a water tank 30 attached to the solar cell panel 6, a housing 10 provided below the roof 204, a water tank 12 provided in the vicinity of the roof 204, a radiator 14 provided in the housing 10, a hot air outlet port 16, a fan 18, a pump 24 or the like. Then, the fan 18 and the pump 24 are driven by an electric power generated in the solar cell panel 6. Water in the water tank 30 is circulated to the radiator 14 by the pump 24. Hot air is produced by heat generated by the solar cell panel 6 and is blown out by the fan 18. |
