A PolyU startup co-founded by Prof. DAI Jianguo, Management Committee Member of the Research Institute for Land and Space (RILS), initiated pilot schemes to apply “UmiCool”, a sub-ambient cooling coating developed by the team, to various building structures in Hong Kong and mainland China, hence achieving cooling and energy saving effects and reducing the reliance on air conditioning.
The UmiCool coating uses patented fluorescent cooling technology and can be painted onto the exterior walls of buildings to effectively reduce indoor temperature. Umicool absorbs UV radiation in the sunlight and converts it into infrared radiation for re-emission. It can reach up to 97% in solar reflectance, and can lower the indoor temperature by up to 4 degrees Celsius. The start-up co-founded by Prof. Dai, Umi Coating New Material Technology Co., Limited, collaborated with the Electrical and Mechanical Services Department and the Home Affairs Department of the HKSAR, to conduct pilot projects in applying UmiCool to building structures in Tung Chung and Mui Wo in Lantau Island, as well as rooftops of squatter huts in Pokfulam villages, respectively.This technological innovation was awarded several international patents and won a Gold Medal in the 2022 Geneva Inventions Expo. The startup is planning to establish a sales and production base in Foshan, Guangdong to expand its business in the Greater Bay Area. In the future, the company will expand its technology to other regions and encourage individuals to adopt environmentally friendly and energy-saving coatings.
