1. Cross-ventilation: This strategy involves using openings on opposite walls or sides of a building to facilitate natural air flow.
2. Stack ventilation: Hot air rises and cool air descends, so stack ventilation takes advantage of this natural phenomenon by creating openings at the top and bottom of a building to allow hot air to escape and cool air to enter.
3. Wind-driven ventilation: This strategy uses the natural movement of wind to induce air flow through a building.
4. Solar chimney: A solar chimney is a passive solar ventilation system that uses the sun's energy to heat air and create air flow through a building.
5. Night purging: This is the process of flushing out warm air from a building at night when the outside air is cooler, in order to reduce the internal temperature of the building.
6. Ventilation via vegetation: Strategically placing plants and greenery in a building can help to regulate temperature and improve air quality through natural transpiration.
7. Ceiling fans: Ceiling fans are a simple and effective way of improving air flow within a room, without the need for complex mechanical systems.
