Hot areas need to be well ventilated, and Zhou Xiang should be considered in the plan and profile design of the building. The main use rooms should be arranged on the windward side of the summer, and the auxiliary rooms can be arranged on the leeward side, and the construction structure and auxiliary measures should be used to improve the ventilation effect. When the air inlet of the room cannot directly face the dominant wind direction in summer, wind deflectors, greening and staggered plane layout can be adopted to guide the wind into the room. The layout of the openings of doors and windows should try to make the indoor airflow field evenly distributed and cover the main functional areas in the room. In hot areas in summer, large openings should be opened as much as possible to promote natural ventilation. The opening of the door and window is optimal for penetration, reducing the resistance and detour of the indoor airflow. The use of openings such as stairwells and patios to form hot-pressed ventilation to guide the airflow into the room from the openings of low-level doors and windows to organize ventilation.
