Achieving indoor thermal comfort is essential for productivity, especially in educational environments, and hence has recently attracted considerable attention. Phase change materials (PCMs) integrated into various building components have been used to improve the indoor temperature. In this study, the effectiveness of integrating macro-encapsulated BioPCMs into the walls and ceilings of lecture halls in an educational building was determined via simulation. The simulations considered a hot climate coupled with controlled night ventilation of 15 air change per hour for enhancing the indoor temperature. Using the EnergyPlus software, simulations were performed for different PCM melting temperatures (25, 27 and 29°C) and thicknesses. The PCM with a melting temperature of 27°C yielded a notable reduction (0.5–3.3°C) in the indoor temperature. Furthermore, increasing the layer thickness to 3.75 cm had little effect on the temperature, as indicated by the incomplete charging process during the night.

实现室内热舒适度对于生产力至关重要，尤其是在教育环境中，因此最近引起了相当大的关注。集成到各种建筑组件中的相变材料 (PCM) 已被用于改善室内温度。在这项研究中，通过仿真确定了将宏观封装的 BioPCM 集成到教育大楼报告厅的墙壁和天花板中的有效性。模拟考虑了炎热的气候，加上每小时换气 15 次的受控夜间通风，以提高室内温度。使用 EnergyPlus 软件对不同的 PCM 熔化温度（25、27 和 29°C）和厚度进行了模拟。熔化温度为 27°C 的 PCM 使室内温度显着降低（0.5-3.3°C）。
