By adding the insulation with phase change material (PCM), the building's thermal resistance was enhanced. Relying on the capabilities of DesignBuilder, 3584 different cases were defined to determine the effect of different input parameters on energy consumption. The results showed that instead of using insulation or PCM, it is better to use a combination of insulation and PCM. The location of PCM + insulation has a great impact on the energy consumption of the building. For the supposed climate zones, the best installation location was different. For the city of Jeddah, PCM with a temperature of 28 °C was suitable, but for Riyadh, with the increase of the setpoint temperature, it is required to install PCM with a higher phase change temperature. By choosing the best layout from the combination of PCM and insulation, the building energy consumption was reduced by 36 % and 41 %, respectively.

采用相变材料的建筑具有更好的耐热性的新结构：与普通墙壁相比，对热变化的反应更温和


通过添加相变材料（PCM）隔热层，建筑物的热阻得到增强。依靠DesignBuilder的功能，定义了3584种不同的情况，以确定不同输入参数对能耗的影响。结果表明，最好使用绝缘和 PCM 的组合，而不是使用绝缘或 PCM。 PCM+保温材料的位置对建筑的能耗影响很大。对于假定的气候区域，最佳安装位置是不同的。对于吉达市来说，温度为28℃的PCM是合适的，但对于利雅得来说，随着设定温度的升高，需要安装更高相变温度的PCM。通过选择PCM和保温材料组合的最佳布局，建筑能耗分别降低了36%和41%。
