HK Tech 300: i2Cool – From the Lab to the Community

The weather in Hong Kong is hot and humid over the summer, and indoor temperatures can be even more uncomfortable. Air-cons help but aren’t environmentally friendly, and electricity bills are expensive.

Some relief is offered in the form of a special paint developed thanks to seed and angel funding from HK Tech 300. The start-up i2Cool has developed the innovative passive radiative paint inspired by the surface hair structure of a Saharan silver ant that can resist the heat of a blazing sun. The paint simultaneously reflects most of the sunlight on an exterior wall and then dissipates the building's heat into the atmosphere through mid-infrared radiation. This process significantly drops the building's indoor temperature, saving energy and helping to achieve carbon neutrality. The paint has already been applied in buildings, storage facilities and outdoor facilities in Hong Kong.

The CityU team hopes to apply this innovative technology in Hong Kong to benefit as many people as possible such as residents in overcrowded living environments, making rooms cooler and reducing electricity use.

HK Tech 300：i2Cool — 從實驗室走到香港社區

香港夏天又熱又濕，室溫亦會隨之升高，冷氣雖可有助降溫，但冷氣費高昂，亦不環保！

獲得HK Tech 300種子及天使基金的初創團隊 — i2Cool Limited 創冷科技有限公司 ，就利用銀蟻散熱嘅原理，研發出一種製冷塗層，將塗料油上建築物外牆後，可反射大部分太陽光，將建築物的熱能以中紅外輻射方式散發到外太空，令建築物溫度降低，從而減少電力消耗及溫室氣體排放，幫助社會向實現碳中和的目標邁進！ 製冷塗層現時已先後應用於香港的建築物、恆温貨櫃箱及地盤電池系統等等。

除商業合作外，團隊更希望將技術應用於香港社區上不同地方，令更多人受惠，例如基層市民擠迫的住所，令屋內變得涼快，從而減少用電量及電費。

🎥一齊看看下他們的初創成果吧！
