Windcatcher as a Persian Sustainable Solution for Passive Cooling

Abstract

Currently, building energy consumptionhas become an international issue especially in developing countries. In hot arid climate,60% of total building energy consumptionin this areais associated with cooling systems. Wind as an important renewable energy can play a prominentrole to supply natural ventilation inside the building and windcatcher as a traditional technique can be implemented for this purpose. In this paper the different types of windcatchers, its performance and functionwas reviewed. It can be concluded in most area this technique can be successfully be employed and help to reduce fossil energy consumption and related CO 2 emissions.
