Abstract: Building energy conservation and carbon reduction have significant implications for low-carbon development. In order to gain a deeper understanding of the application and research progress of phase change materials in building envelope materials, the selection, modification methods, and typical applications of phase change materials were sorted out. Considering that there are still certain limitations in their energy efficiency performance, the latest progress and improvement effects of phase change materials in key performance optimization such as thermal conductivity enhancement, supercooling suppression, leakage reduction and stabilization, gradient function, dual energy coupling, and collaborative regulation were analyzed, in order to provide reference for further promoting the research and application of phase change materials in buildings.
