Dr. Edwin Tso wins Gold Medal with Congratulations of the Jury at the Inventions Geneva Evaluation Days (IGED) 2021
“An Energy-Free, Low-Cost and High Cooling Performance Passive Radiative Cooling Technology for Building Applications” led by Dr. Edwin Tso, Assistant Professor, received the Gold Medal with Congratulations of the Jury at Inventions Geneva Evaluation Days (IGED) 2021. IGED, held from 10 to 14 March 2021, is a special edition of the International Exhibition of Inventions of Geneva due to the pandemic. It is one of the biggest global events showcasing innovations and inventions from around the world. The award obtained by Dr. Tso, at such a high international level, demonstrates the excellence of the research carried out at SEE.
To provide a sustainable and energy-saving solution to the consumption of electricity in buildings, Dr. Tso has developed a passive radiative cooling paint, using the universe as a cooling source. Unlike traditional air-conditioning systems, the passive radiative cooling paint is an energy-free and refrigerant-free cooling technology that reflects incoming solar irradiance, while emitting thermal radiation to the cold universe and achieving sub-ambient cooling.
This self-cooling technology possesses many advantages, such as a simple structure, easy manufacturing, and low cost. Directly coating this paint on a building’s roof or exterior walls will reduce its surface temperature and save on air-conditioning energy. The technology can be used for cooling automobile, in self-cooling textiles and painting roads to mitigate heat from land.
