The use of phase change material as an efficient way to use building energy has recently been discovered as this material occupies 40 % of the total carbon emissions through energy used in the building sector. In order to apply phase change materials to buildings, phase stabilization must first be achieved; some researchers have developed shape-stabilized phase change material (SSPCM). In this study, the enthalpy-temperature function based on the thermal properties of 22 types of SSPCMs were analyzed and applied to a dynamic energy simulation program. The SSPCM was applied to improve the low heat storage performance of wooden buildings along with building energy savings. The SSPCM was applied to the inner side of a 20-mm-thick external wall in a case study concerning the inside and outside of an external wall. An analysis of the annual energy consumption of buildings showed that applying SSPCM resulted in average savings of 5 %. To confirm the improvement in the heat storage performance of buildings, the indoor temperature behavior during the heating and cooling periods was analyzed. Maintaining the thermal inertia of SSPCM was found to have reduced the peak temperature in summer by 4.1 °C.

最近发现相变材料作为一种有效的建筑能源利用方式，因为这种材料占建筑部门所用能源的碳排放总量的40％。为了将相变材料应用于建筑物，必须首先实现相稳定。一些研究人员已经开发出形状稳定的相变材料（SSPCM）。在这项研究中，分析了基于22种SSPCM的热特性的焓-温度函数，并将其应用于动态能量模拟程序。SSPCM用于改善木制建筑的低蓄热性能，并节省建筑能耗。在关于外墙内外的案例研究中，将SSPCM应用于厚度为20毫米的外墙内侧。对建筑物的年能耗的分析表明，应用SSPCM可以平均节省5％。为了确认建筑物的储热性能的改善，分析了供暖和制冷期间的室内温度行为。发现保持SSPCM的热惯性可使夏天的峰值温度降低4.1°C。
