The thermal comfort of occupants is a necessary requirement for any building. The present pandemic demands us to opt for natural ventilation over air-conditioned spaces to reduce the spread of the infection. This work aims to prevent air-conditioner usage in a commercial building in India during daytime office hours while simultaneously enhancing the thermal comfort of the building occupants through natural ventilation/Phase Change Material (PCM)/insulation techniques. Four building configurations, such as Building A (conventional building with no PCM and no insulation), Building B (building-integrated with PCM), Building C (building-integrated with insulation) and Building D (building-integrated with PCM and insulation) were analysed for various locations using DesignBuilder software. From the results, it is understood that insulation integration is recommended for locations with average nighttime temperatures greater than 27°C, while PCM integration is recommended for locations with an average nighttime temperature less than 27°C during the summer season. Also, nighttime cooling of the building through an air-conditioner is necessary for all locations during summer to maintain adequate thermal comfort with natural ventilation in the daytime. Finally, an appropriate PCM/insulation technique is recommended for an office building located in each location that falls under each type of climate. Hence, the selection of PCM/insulation technique is to be made based on the specific site conditions.

通过相变材料和绝缘技术为印度写字楼打造健康自然通风的室内建筑环境的途径
居住者的热舒适性是任何建筑的必要要求。当前的大流行要求我们在空调空间上选择自然通风,以减少感染的传播。这项工作旨在防止印度商业建筑在白天办公时间使用空调,同时通过自然通风/相变材料 (PCM)/隔热技术提高建筑居住者的热舒适度。四种建筑配置,例如A楼(无PCM和隔热层的常规建筑)、B楼(PCM集成建筑)、C楼(隔热层集成建筑)和D楼(PCM和隔热层集成建筑)使用 DesignBuilder 软件对不同位置进行了分析。从结果来看,据了解,夜间平均温度大于27°C的地方建议采用保温一体化,夏季夜间平均温度低于27°C的地方建议采用PCM一体化。此外,夏季所有地点都需要通过空调在夜间对建筑物进行冷却,以在白天通过自然通风保持足够的热舒适度。最后,对于位于各种气候下的每个位置的办公楼,建议采用适当的 PCM/绝缘技术。因此,PCM/绝缘技术的选择应根据具体的现场条件进行。而对于夏季平均夜间温度低于 27°C 的位置,建议使用 PCM 集成。此外,夏季所有地点都需要通过空调在夜间对建筑物进行冷却,以在白天通过自然通风保持足够的热舒适度。最后,对于位于各种气候下的每个位置的办公楼,建议采用适当的 PCM/绝缘技术。因此,PCM/绝缘技术的选择应根据具体的现场条件进行。而对于夏季平均夜间温度低于 27°C 的位置,建议使用 PCM 集成。此外,夏季所有地点都需要通过空调在夜间对建筑物进行冷却,以在白天通过自然通风保持足够的热舒适度。最后,对于位于各种气候下的每个位置的办公楼,建议采用适当的 PCM/绝缘技术。因此,PCM/绝缘技术的选择应根据具体的现场条件进行。对于位于各种气候条件下的每个位置的办公楼,建议采用适当的 PCM/隔热技术。因此,PCM/绝缘技术的选择应根据具体的现场条件进行。对于位于各种气候条件下的每个位置的办公楼,建议采用适当的 PCM/隔热技术。因此,PCM/绝缘技术的选择应根据具体的现场条件进行。
