Abstract

The interest to ensure thermal comfort becomes one of the major challenges in the building sector, not only for the quality of interior ambiences, but also to minimize the energy rate consumed for heating and cooling systems. Th s paper presents the advantage of using the adaptive approach and numerical simulation to assess the level of thermal comfort of dwellings of different architectural typology in hot climate. For this purpose, the method is based on in situ measurements effected on two samples of traditional and contemporary typology; using anemometer instrument, where the climatic parameters measured inside and outside samples are: ambient temperature, relative humidity rate and air velocity. The simulation work is performed by Energy-Plus software; consequently experimental tests are realized on the local material in order to know their physical and thermal characteristics. The results obtained demonstrate the efficiency of the traditional passive devices, which are able to provide a comfortable thermal ambience without referring to the air conditioning system, with an operating temperature of 30.5ºC and a satisfaction rate of 80%.

基于现场测量和动态模拟的夏季热舒适性评价——以阿尔及利亚-撒哈拉地区炎热干旱气候为例

确保热舒适成为建筑领域的主要挑战之一，不仅要保证室内环境的质量，还要尽量减少供暖和制冷系统的能耗。本文介绍了采用自适应方法和数值模拟方法评价热气候条件下不同建筑类型住宅热舒适水平的优点。为此，该方法基于对传统和现代类型学两个样本的原位测量;采用风速仪，其中测得样品内外的气候参数为:环境温度、相对湿度和空气流速。仿真工作由Energy-Plus软件完成;因此，对局部材料进行了实验测试，以了解其物理和热特性。实验结果表明，传统无源装置在不依赖空调系统的情况下，能够提供舒适的热环境，工作温度为30.5℃，满意率为80%。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
