Abstract

PurposeLife experience in hot and arid areas of Iran has proved that in the transitional seasons (spring and autumn) in which the climate is not too hot, passive cooling systems such as windcatchers (baadgir) have functioned well. This paper intends to investigate the efficiency of a single-side windcatcher as a passive cooling strategy; the case study is the Bina House windcatcher, located in Khousf town, near Birjand city, Iran.Design/methodology/approachTo achieve the aim, air temperature, relative humidity, wind data and mean radiant temperature were measured by the related tools over five days from September 23 to October 23. Then, the thermal performance of the windcatcher was examined by analyzing the effects of all these factors on human thermal comfort. Quantitative assessment of the indoor environment was estimated using DesignBuilder and its computational fluid dynamics (CFD) tool, a thermal comfort simulation method to compare the cooling potential of the windcatcher. Windcatcher performance was then compared with two other common cooling systems in the area: single-side window, and evaporative cooler.FindingsThe results showed that both windcatcher and evaporative cooler can provide thermal comfort for Khousf residents in the transitional seasons; but the difference is that an evaporative cooler needs to consume water and electricity power, while a windcatcher is a passive cooling system that uses clean energy of wind.Originality/valueThe present study, by quantitative study of single-side windcatchers in a desert region, measured the climatic factors of a historical house and compared it with thermal comfort criteria. Therefore, the results of field measurements were analyzed, and the efficiency of the windcatcher was compared with two other cooling systems, namely single-side ventilation and evaporative cooler, in the two seasons of summer and autumn (transition seasons).

单面捕风器在过渡季节的性能评价(以伊朗呼罗珊省南部Khousf镇为例)

目的:在伊朗炎热和干旱地区的生活经验证明，在气候不太热的过渡季节(春季和秋季)，诸如捕风器(baadgir)之类的被动冷却系统运行良好。本文旨在研究单面捕风器作为被动冷却策略的效率;案例研究是位于伊朗Birjand市附近的Khousf镇的Bina House捕风器。设计/方法/方法为了达到目的，我们在9月23日至10月23日的五天内，利用相关工具测量了空气温度、相对湿度、风数据和平均辐射温度。然后，通过分析这些因素对人体热舒适的影响，考察了捕风器的热性能。使用DesignBuilder及其计算流体动力学(CFD)工具对室内环境进行定量评估，CFD是一种热舒适模拟方法，用于比较捕风器的冷却潜力。然后将捕风器的性能与该地区另外两种常见的冷却系统(单面窗和蒸发冷却器)进行比较。结果表明:在过渡季节，捕风器和蒸发冷却器均可为胡斯夫居民提供热舒适;但不同的是，蒸发冷却器需要消耗水和电力，而捕风器是一种使用清洁能源风能的被动冷却系统。本研究通过对沙漠地区单侧捕风器的定量研究，测量了一座历史建筑的气候因素，并将其与热舒适标准进行了比较。因此，对现场实测结果进行了分析，并在夏季和秋季两个季节(过渡季节)将捕风器与单侧通风和蒸发冷却器两种冷却系统的效率进行了比较。

期刊介绍： The International Journal of Building Pathology and Adaptation publishes findings on contemporary and original research towards sustaining, maintaining and managing existing buildings. The journal provides an interdisciplinary approach to the study of buildings, their performance and adaptation in order to develop appropriate technical and management solutions. This requires an holistic understanding of the complex interactions between the materials, components, occupants, design and environment, demanding the application and development of methodologies for diagnosis, prognosis and treatment in this multidisciplinary area. With rapid technological developments, a changing climate and more extreme weather, coupled with developing societal demands, the challenges to the professions responsible are complex and varied; solutions need to be rigorously researched and tested to navigate the dynamic context in which today''s buildings are to be sustained. Within this context, the scope and coverage of the journal incorporates the following indicative topics: • Behavioural and human responses • Building defects and prognosis • Building adaptation and retrofit • Building conservation and restoration • Building Information Modelling (BIM) • Building and planning regulations and legislation • Building technology • Conflict avoidance, management and disputes resolution • Digital information and communication technologies • Education and training • Environmental performance • Energy management • Health, safety and welfare issues • Healthy enclosures • Innovations and innovative technologies • Law and practice of dilapidation • Maintenance and refurbishment • Materials testing • Policy formulation and development • Project management • Resilience • Structural considerations • Surveying methodologies and techniques • Sustainability and climate change • Valuation and financial investment
