Energy saving and natural ventilation and cooling systems
The Optimization of energy supply exploitation is not derived only from an ecological conscience, but it is a necessity deduced by the possible limited sources of supply.
The design must take into account:
- the technological aspectsbut also of building techniques which limit, naturally, the use of air conditioning systems,
- knowledgeof traditional (and ancient) tropical and Equatorial band construction techniques; all in reference to:
- wind towersknown as “Ancient Egypt” and “malqaf bâdgir” in Persia, mud brickof Yazd are better developed and preserved in the Middle Ea
Passive cooling technique of wind towers:
- evaporative cooling.
Wind Tower can dissipate heat either using:
- the temperature difference,
- natural ventilation.
To the base of the towers, connected to the central hall of the house, is often a tank containing water, which for evaporate -transpiration effect cools and humidifies the indoor areas.

Contemporary applications: flexible and integrated architecturally, the Tower of wind is often innovative aesthetic-functional trials of interesting protagonist.
Even in different climates from dry-arid, the constant change of air generated by the wind towers is a comfort factor more than relevant, because it not only lowers of the temperature, but also decreases the heat sensed and purifies the air and oxygen supply.
