Windcatchers and their applications in contemporary architecture

Abstract

Natural ventilation and cooling have played an essential role in providing comfort conditions. Windcatchers are passive cooling systems and one of the most familiar elements in Iranian architecture. They can significantly influence on reduce cooling loads and supply the necessary ventilation rate of buildings. This paper aims at providing an in-depth review of the recent developments and applications of windcatchers in modern architecture. The efficiency of windcatcher is also discussed according to the windcatcher's relevant parameters, i.e., height, configuration, and cross-section. This comprehensive review reveals that these factors have significant impacts on the performance of windcatchers. It is also shown that a one-sided windcatcher is a better choice in regions with privileged wind direction. However, other types of it are better in regions with variable wind directions. Finally, windcatchers' potential for applying in the contemporary architecture and urban planning shown in the using windcatcher in contemporary buildings, windcatchers in the urban context, new designs, and new technologies of windcatchers sections.
