L building 300 square meters hotel, do you want to do tobacco control? What size fan should I use? Thank you, everyone is a master.

There is no need to control smoking. . . The eighth floor belongs to a high-rise building. The high specification stipulates that the inner walkway is more than 20m. Or there are windows on both sides of the aisle, and the window area meets the requirements of the code, so there is no need to do smoke control. In addition, it is a high-rise building. If there is no natural smoke exhaust in rooms over 65,438+000 square meters, smoke control facilities should also be made. You said that the first floor of this hotel is only 300 square meters. After the conversion, the inner walkway will not exceed 20 meters, so the smoke control can be ignored.
