Abstract

This article conducted a comprehensive study on a three-story residential building in Yazd, Iran, which was meticulously modeled using DesignBuilder. The primary objective was to investigate the impact of BioPCMs (Bio Phase Change Materials), which are environmentally friendly materials, on the building’s thermal performance. For this purpose, BioPCM® M182/Q21 was selected due to its effectiveness in enhancing energy efficiency. The study involved a practical comparison of the building’s energy consumption under three scenarios. The first scenario represented the baseline condition where no PCM was used. The second scenario incorporated PCM into the external walls, while the third scenario extended the use of PCM to both the external and internal walls. In the second scenario, where PCM was applied only to the external walls, there was a 9% reduction in annual energy consumption. The third scenario, which utilized PCM in both the external and internal walls, resulted in a reduction of 15.5% in annual energy consumption. Additionally, when PCM was used in both the external and internal walls, the total energy consumption for cooling and heating the building decreased by 5.4% and 18.9%, respectively.

在建筑物外墙和内墙同时使用 PCM 层对年能耗的影响
本文对伊朗亚兹德的一栋三层住宅楼进行了全面研究,并使用 DesignBuilder 对其进行了细致的建模。主要目的是研究环保材料 BioPCM(生物相变材料)对建筑物热性能的影响。为此,我们选择了 BioPCM® M182/Q21,因为它能有效提高能源效率。这项研究对三种情况下的建筑能耗进行了实际比较。第一种情况是不使用 PCM 的基准条件。第二种情况是在外墙使用 PCM,第三种情况是在外墙和内墙都使用 PCM。在第二个方案中,只在外墙使用了 PCM,每年的能耗减少了 9%。第三种方案在外墙和内墙都使用了 PCM,年能耗减少了 15.5%。此外,在外墙和内墙都使用 PCM 时,建筑物制冷和供暖的总能耗分别减少了 5.4% 和 18.9%。
