Badgir: Designe with Nature, A Traditional Architectural and Climate Element in Hot Dry Region of Iran

Abstract

Perfonnance and energy consumption in buildings are considered to be the most important factor in climate. Today energy consumption reduction requirement is purpose of climatic sensitivity depending on the use of natural resources and promoting comfort in life, healthy and sustainable living spaces, and sustainable building design. Nowadays sustainable design and construction strategies have great importance. Wind, as the source of renewable energy, is the vital factor in climate studies. Wind is the most significant factor used by architects in building design in order to natural ventilation. Badgir -Wind catcher or Wind tower- is a wind dependent and wind driven architectural element, as component ofEco Architecture is depending on natural, climatic phenomena and renewable energy sources. The operating system of badgir depends on the air convection and evaporation. The most important function of the Badgir is cooling the building interior with natural methods without consuming energy in hot, dry or humid areas. The most effective role of Badgir is the reduction of heat and adjustment of temperature of inner life spaces on the basis of comfort with the help of natural convection currents of clean air ventilation.
