On June 2, 2021, all 11 venues of the 2022 Winter Olympics have passed the green building certification. Since the stage of applying for the Winter Olympics, China has solemnly promised to the international community to host a blueprint for the "Low-Carbon Winter Olympics". In the process of building the Green Winter Olympics, THTF has taken scientific research as the forerunner, deeply promoted the application of key special technologies and independent products of the "Science and Technology Winter Olympics". Through the swarm intelligence technology jointly developed with Tsinghua University, the whole process of real-time collection and analysis of the ice surface data of the "Ice Cube" is achieved to achieve more precise environmental temperature and humidity control, and create a wonderful space of "same room and different temperature" in the stadium and the auditorium. Under the goal of "carbon neutrality and carbon peaking", the THTF power of green development will be empowered by digitalization.
