<P>PROBLEM TO BE SOLVED: To provide a ventilation structure wherein appearance of a building is kept favorably and ventilation efficiency is improved. <P>SOLUTION: This ventilation unit 10 for ventilation of a plurality of rooms provided in a building 1 has: a ventilation unit body 11; outside air intake piping 12 for introducing outside air into the ventilation unit body 11; and indoor air exhaust piping 14 for exhausting indoor air from the ventilation unit body 11. An exhaust port 31 opened facing the outside air is provided on a roof 3 of the building 1, at least a part of an exterior wall 2 of the building 1 is provided inside with an air passage 21 communicating to the exhaust port 31, and the indoor air exhaust piping 14 is made to communicate to the air passage 21. Thus, since the position of the exhaust port 31 is placed sufficiently far from the opening of the outside air intake piping 12, fresh outside air is introduced all the time to improve ventilation efficiency, and since there is no opening of the indoor air exhaust piping 14 provided on the exterior wall 2, appearance of the building 1 is made favorable. <P>COPYRIGHT: (C)2003,JPO |
