i2Cool is a tech start-up based in Hong Kong. This start-up began as a research-based project. The group had spent over seven years developing passive radiative cooling technology. After years of testing and modification, the expensive passive radiative cooling technology has successfully been converted into an affordable commercial product that everyone can benefit from. And this led to the establishment of i2Cool in June 2021. 

i2Cool has consistently followed the development strategy of "green, energy-saving, zero-carbon upgrading, carbon peaking and carbon neutrality goals innovation and development," maintained the leading position in the industry's technology through independent innovation, and contributed consistently to the development of a greener, more sustainable world.
