。Furthermore, a predetermined amount of air is introduced from both the left and right ventilation passages 18 in FIG.
The flow rate of air in the upward direction within the interior is significantly increased compared to conventional systems, significantly improving ventilation performance. Therefore, the living environment of each corridor 12 and each residential part of the middle class part facing the open-air part 11 is improved. In addition, the negative pressure inside the atrium 11 is reduced by the flow of a large amount of air, which eliminates the difficulty of opening and closing the doors of each dwelling unit and of drawing air into the room.
