Earth Air Tunnel - Circulation of the air through the ground to cool it before entering the space. The air must circulate at least 2 Meters deep below the ground surface. The pipe openings is protected to keep insects and rainwater from entering. This strategy can be used in Dry tropics. This type of ventilation does not work, if the level of the water is higher than the buried piping. Check or verify the depth before applying this technique. - The barefoot architect (A handbook for green building)
