1. The form of natural ventilation air supply and exhaust should strive to meet the requirements for the formation of ventilation.
2. When the fresh air and exhaust vents of new buildings are set on the load-bearing wall, holes should be reserved during the main construction. When a new air outlet is added on the load-bearing wall of an existing building, the original design unit should be reported to the original design unit for design and verification to meet the minimum opening size and opening position requirements of the structure. If the requirements are not met, reinforcement treatment should be performed.
3. For the air inlet of natural ventilation, doors, holes, casement windows or vertically rotating windows, panels, etc. should be used according to the process characteristics. The sash used for natural ventilation should be easy to open and close manually. For window sashes that are inconvenient for manual switching or need to be adjusted frequently, switch devices should be provided.
4. Hospital buildings with shutters as natural ventilation inlets should take measures to prevent rainwater from entering.
