通过实验研究和模拟分析来评估智能屋顶系统的湿热性能，该系统在夏季进行被动除湿，在冬季通过屋顶通风层进行空气循环来收集太阳能热量，以利用太阳能减少显热和潜热负荷。利用具有良好调湿性能的纤维绝热材料，可以开发出潜热和显热分离的高效空调系统。从非等效热力学的角度阐述了智能皮肤系统基于势能的被动散热和太阳能收集的基本原理。对智能屋顶的温湿度波动特性进行了实验和数值模拟。这项工作使热和水分运动的围护结构系统的综合分析。实验和数值模拟结果表明，显热和潜热的减少可以通过使用可再生能源运行的系统实现。
Experimental studies and simulation analysis were conducted to assess the hygrothermal performance of intelligent roof systems, which perform passive dehumidification in summer and solar heat collection in winter by air circulation through the roof ventilation layer to reduce sensible and latent heat load using solar heat. A high-efficiency air conditioning system separating latent and sensible heat can be developed using fibrous insulation with excellent moisture conditioning properties. The thermodynamic-potential-based fundamental principle of the intelligent skin system, which performs passive dehumidification and solar collection, was explained based on non-equivalent thermodynamics. The performance characteristics of temperature and humidity fluctuations of the intelligent roof were experimentally and numerically demonstrated. This work enables the combined analysis of heat and moisture movement in the envelope system. The experimental and numerical simulation results indicate that significant sensible and latent heat reduction can be achieved by running the system using renewable energy.
