Abstract: PROBLEM TO BE SOLVED: To provide a livestock barn that is the livestock barn for use in cold districts and has a structure where water droplet is hard to be accumulated in an attic.SOLUTION: A ventilation fan 30 is directly mounted to a roof 14 in a comparative example in Fig. (a). The airflow becomes high right under the ventilation fan 30 and air stagnation 36 is generated in an intermediate portion between the ventilation fan 30 and the adjacent ventilation fan 30. When air gets wet and the roof 14 is cooled by the outside air at low temperature, dew condensation is caused in the back of the roof 14 in the intermediate portion between the ventilation fan 30 and the adjacent ventilation fan 30. When this dew condensation is collected, it becomes the water droplet and falls. In the embodiment in Fig. (b), the air under the roof 14 is once gathered under a roof truss 23, and then is discharged with the ventilation fan 30. Namely, the airflow can be averaged by the roof truss 23 and a narrow wall 22, and therefore the occurrence of the air stagnation 36 shown in the Fig. (a) can be suppressed.SELECTED DRAWING: Figure 5
