Research direction: Advanced Building Energy Efficiency Technologies, Low-carbon Smart Building Envelopes, Sustainable Urban Building Energy Conversion and Utilization

LIU Sai, Youth Chair Professor at Southeast University, Ph.D. supervisor, leading a national-level youth talent program. He earned a Bachelor’s degree from Hunan University, a Master’s degree from the Hong Kong University of Science and Technology, and a Ph.D. from the City University of Hong Kong, followed by postdoctoral research at the City University of Hong Kong.

He is currently engaged in research on advanced building energy-saving technologies, low-carbon intelligent building envelopes, and sustainable urban building energy conversion and utilization within Professor Cao Shijie’s Sustainable Built Environment research group (https://arch.seu.edu.cn/csj/main.htm). His work emphasizes leveraging smart new technologies/ new materials to achieve efficient conversion and precise regulation of natural light and thermal energy. Spanning from individual buildings at the micro level to urban scales at the macro level, the research aims to optimize human thermal environments and promote widespread applications of zero-carbon energy solutions in architecture. In recent years, He has published multiple first-authored papers in high-impact journals such as Nature Communications, Advanced Materials, Advanced Functional Materials, Advanced Science, and Applied Energy, including three cover/back cover articles. The research achievements have been recognized with several international awards, including the Gold Medal at the Geneva International Exhibition of Inventions, Gold Prize in the China International Internet+ Innovation and Entrepreneurship Competition, and Gold Award at the Canadian International Invention and Innovation Competition.
