Ventilating a high rise building requires a comprehensive system that takes into account the building’s size, layout, and climate. The most common approach is to install a mechanical ventilation system, which uses fans to draw in fresh air from outside and exhaust stale air from inside. This system can be supplemented with natural ventilation, such as windows and vents, to provide additional air flow. Additionally, air filters should be installed to ensure that the air quality is maintained. Finally, the system should be regularly inspected and maintained to ensure that it is operating efficiently and safely.
