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:

  1. the technological aspectsbut also of building techniques which limit, naturally, the use of air conditioning systems,
  2. 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:

  • ventilation,
  • 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.
