Abstract

Abstract This paper explores the impact of balconies on the energy demand required for cooling in the arid climate zone of the city of Adrar, in Algeria. For the purpose to assess several situations of the balconies, we have chosen a parametric method based on a campaign of thermal simulations. The open and eliminated balcony type were selected and characterized by four parameters: the balcony to room ratio, the orientation, the window type, and the balcony position. A set of 100 simulations was selected randomly based on the Monte-Carlo probability technique. The final sample was corrected based on Cook’s distance which gave 85 simulations as a final sample size. A generalized regression model was performed to identify the impact of each parameter. The accuracy of the model is above 97% and the sensitivity analysis shows that the most important factor is the balcony to room ratio which could reduce the energy demand up to 26% followed by the window type (24%), the orientation (8%) and the balcony position (5%). This conclusion stresses the idea of considering the balcony as a passive solution to reduce the cooling energy demand.

探索在干旱气候地区,阳台对制冷能源需求的影响
摘要:本文探讨了阿尔及利亚阿德拉尔市干旱气候区阳台对冷却所需能源需求的影响。为了评估阳台的几种情况,我们选择了一种基于热模拟的参数化方法。选择了开放式和封闭式阳台类型,并通过阳台与房间的比例、朝向、窗户类型和阳台位置四个参数进行表征。基于蒙特卡罗概率技术,随机选取了100组模拟。最后的样本是根据库克的距离进行修正的,它给出了85个模拟作为最终的样本大小。采用广义回归模型来确定各参数的影响。模型的精度在97%以上,敏感性分析表明,最重要的因素是阳台与房间的比例,可以减少能源需求高达26%,其次是窗户类型(24%),朝向(8%)和阳台位置(5%)。这一结论强调了将阳台作为一种被动解决方案来减少冷却能源需求的想法。
