PROBLEM TO BE SOLVED: To provide an exhaust system for rapidly exhausting a gas leaked from a facility provided in a building out of the building without dispersing within the building by use of an air flow formed by air conditioning provided in the building. SOLUTION: In this exhaust system for exhausting a specified gas lighter in specific gravity than air, which is provided in the building having a facility treating the gas, an exhaust port 13 communicating with the outside of the building is provided above a gas generating facility 25, an outlet port 17 of air conditioning is provided on a floor 16, and an intake port 12 of air conditioning is provided on a ceiling 11, so that an air flow by air conditioning running from the floor 16 to the ceiling 11 is formed around a place where the specified gas 30 is generated. The ceiling 11 is formed with a gradient so that the exhaust port 13 is located in the highest position of the ceiling 11. The floor part of the building 10 is formed in a double floor with the floor 16 being a panel type floor, and the ceiling part is formed in a double ceiling with the ceiling 11 being a panel type ceiling.
