Abstract
Vernacular and traditional Iranian architecture has always acted rationally, harmoniously, and climate-friendly to meet the needs of the people in dealing with the environment. In addition, without harming the environment, they have achieved the best initiatives with the least facilities. For example, we can mention that the Ab-Anbars in arid and desert areas of Iran, which are used to store water in seasons with precipitation for use in the rest of the year, has been an optimal way to use natural resources and provide climate comfort. The Ab-Anbars are realized with ventilated cisterns through openings on their roof or wind-catchers to keep the water cool and provide comfortable conditions for the occupants. In order to study the essential role of natural ventilation and cooling in the Ab-Anbars, thermal analysis with CFD software was carried out to assess the effectiveness of a typical wind-catcher according to different wind directions in Yazd city. The results showed that Ab-Anbars have played an important role in reducing cooling loads and supply the necessary ventilation rate of buildings and can be used in the future for application in contemporary architecture and urban planning.
Highlights
IntroductionVernacular architecture, known as local or regional architecture, is defined as the unconscious “realization” and “embodiment” of the culture of the society with the requirements of the people in nature [1]
The main purpose of this study was to assess the effectiveness of a typical wind-catcher on the natural ventilation and cooling load of Ab-Anbars located in Yazd city, which are one of the masterpieces of the Iranian vernacular and traditional architecture, in hot and dry weather
This study showed that one of the main goals of traditional architects in Yazd in the construction of wind-catchers in the prevailing wind direction has been the maximum use of wind flow for cooling and natural ventilation of the building without using any mechanical means in hot seasons
Summary
Vernacular architecture, known as local or regional architecture, is defined as the unconscious “realization” and “embodiment” of the culture of the society with the requirements of the people in nature [1]. In the traditional housing patterns, all buildings are compatible with the climate and the geography. Iran is a vast country with different climatic zones, and, in the past, traditional builders have presented several logical climatic solutions in order to enhance human comfort. This emphasis has been one of the most important and fundamental features of Iranian architecture. Iranian architecture has been based on climate, geography, available materials, and cultural beliefs [3]
