RADIATIVE COOLING FILM

What is Radiative Cooling Film?

Radiative Cooling Film is a self-developed, electricity-free cooling solution designed for glass surfaces by i2Cool. The material applies the principle of passive radiative cooling technology. By radiating heat to outer space through efficient solar reflection and mid-infrared emission, it effectively reduces indoor temperatures while maintaining building aesthetics and natural daylight. This enables electricity-free cooling and helps reduce air-conditioning energy consumption.

How It Works:

Specially developed for commercial and industrial glass surfaces, our Radiative Cooling Film utilizes high-performance optical microfilms to manage the thermal spectrum. It functions through two primary mechanisms: reflecting solar radiation and emitting mid-infrared heat into the cold void of space. This dual-action process significantly reduces the reliance on air conditioning, blocking UV rays and thermal heat while preserving the building’s aesthetic and viewing clarity.

Electricity-free cooling technology inspired by the Sahara
The Saharan silver ant stays cool using special surface hairs that reflect sunlight and release heat as infrared radiation. This helps it survive in the desert’s extreme heat.
Inspiration
Inspired by the skin structure with the self-cooling function of the Saharan silver ant, i2Cool invented passive radiative cooling technology that can reflect most of the solar heat while effectively emitting thermal energy as mid-infrared into open air space?
Scientific Research
After seven years of research, the i2Cool team overcame cost, production, and construction challenges to develop the Radiative Cooling Film, now available for large-scale use.
