Company Details

i2Cool, a technology-based startup incubated by the CityU HK Tech 300 programme, aims to promote a novel energy-free and environment-friendly passive radiative cooling paint (patented in Hong Kong) for energy-saving and decarbonisation, achieving net-zero buildings. The self-developed and high-performance paint has an edge in solar reflection and thermal emission, resulting in significant sub-ambient cooling effect without consuming electricity and ozone-depleting refrigerants. We will collaborate with different parties and organisations in building, energy and paint industries to effectively demonstrate and promote our paint products. Continuous product and business upgrade will also be conducted to maintain our technical competence and business sustainability. The ultimate goal of i2Cool is to achieve remarkable environmental and social impacts, mitigating energy shortage and climate change, while facilitating overall sustainable development and economic growth in China towards carbon neutrality.

To catch up with global energy transition trends, i2Cool, co-founded by a group of young professionals and scientists from City University of Hong Kong (CityU) who are keen to protect our environment and improve quality of life of human beings through the research outcome in June 2021, is dedicated to advancing the passive radiative cooling technology for energy saving. Unlike traditional air-conditioning systems, the passive radiative cooling is an energy-free and refrigerant-free cooling technology that reflects incoming solar irradiance, while emitting thermal radiation to the cold universe, thereby achieving sub-ambient cooling.
Supported by the CityU HK tech 300 programme, i2Cool has substantially extended the application scenarios of our technology – Passive Radiative Cooling Paint, iPaint, in the past few months, which contributes to enormous amount of energy saved and carbon emissions reduced. Energy crisis is an international problem. It is crucial to facilitate sustainable energy use and electricity-saving technology around the world for possible solutions. To propel global energy transformation, i2Cool has established two strategic directions: (1) expanding into global market, and (2) developing novel, diversified energy-saving products.
