Use of wind cones to cool a building

The optimized form of cones (also called wind cones) uses stack ventilation as well as the wind above the building to create a negative pressure at the top of the cones, which in turn creates air movement in the interior courtyard spaces at the base of the cone and draws cooler air up through the subterranean levels of the city below. At night, the wind cones reverse roles acting as inlet wind towers drawing cool night air downwards to cool the building structure.

These cones should ideally have a tapering form at the top with a wide base.
