Crystal International has been actively investing in cutting-edge energy saving initiatives, as one of the strategies heading towards net zero. To accelerate efficiency upgrades, Crystal is partnering with i2Cool Limited, an award-winning innovator in electricity-free cooling technology. As a pilot project which is currently under installation, the group is adopting the patented technology, iPaint, on the rooftops of two factory buildings at its lifestyle wear factory in China, covering a total area of over 7000 square metres.

By applying electricity-free cooling technology with zero energy consumption – iPaint, the roof surface could result in over 95% of solar reflectivity and mid-infrared emissivity, enabling dual benefits. Firstly, iPaint reduces heat absorption and promotes heat dissipation, achieving zero-energy cooling without electricity or refrigerants. It’s expected to reduce the indoor temperature beneath the roof by around 4-5 degrees Celsius, saving around 200,000 kWh electricity per year for cooling purposes.

The iPaint-applied roof surface also reflects substantial sunlight onto the back of the installed bifacial solar panels, increasing the solar power generation by around 8%.  In addition, it can also enhance weather resistance and corrosion resistance.

Commenting on the latest technology, Catherine Chiu, Vice President of Global Sustainability at Crystal International, said: “Through leveraging the technology from i2Cool, we are making a major step in further enriching our decarbonization strategies to reach net zero. We are keen to uncover more opportunities with pioneering peers to expedite our decarbonisation pace.”

This summer, the factory has also completed the second phase rooftop solar installation, in which part of the installation was building integrated, substituting the aged rain covers to stand against weathering. The total capacity of group-wide solar PV has reached to over 20MW. Crystal International will continue to solicit innovative solutions for low-carbon and greener manufacturing.
