What are the heights of the ninth and tenth floors of the entertainment hall? Calculate the air conditioning load, hurry up! The screenshot of the plan is as follows, please advise, there are several parts of the plan that I can't understand! The height of the story should be combined with the actual structural drawings on site, supporting the drawings of water heating and electricity, and checking the actual elevation under the beam, the height of the ceiling keel and the height of the remaining space after the ground pavement. The height at this time is the net height from the decoration floor to the ceiling;

There are two stairs on the drawing, a shared front room and a staircase front room. Nothing can be used, but it's just an aisle As for being locked without a door, that's impossible. There is no door on the drawing. In other words, this is only a schematic diagram at most, not a design drawing. You can only know what these spaces are doing by asking people who have design drawings. According to the drawing, no matter how small the bathroom is, you need at least two elevators.
