iPaint 1.0

iPaint developed by i2Cool features sub-ambient cooling effect without consuming electricity and refrigerants, resulting in significant building energy saving. Using 1m² of iPaint can save at least 120 kWh of electricity and reduce 70kg CO2 emission annually, equivalent to planting 6.3 trees.

iPaint won Gold Medal with Congratulations of the Jury at the Inventions Geneva Evaluation Days (IGED) 2021


Working Principle

Inspired by the Sahara silver ant with self-cooling effects on their skin, i²Cool invented the iPaint (patented in Hong Kong and mainland China) with strong solar reflectivity (i.e., >95%) and high mid-infrared thermal emissivity (i.e., >94%). The atmosphere of the earth is transparent to mid-infrared, resulting in the thermal energy emitted from iPaint can be effectively dissipated into the cold universe (i.e., -270 ºC). Thus, the electricity-free cooling effect is achieved in iPaint.

iPaint 2.0

To achieve colour display and excellent cooling effects simultaneously, iPaint2.0 selectively reflects visible light and highly reflects the UV and near infrared.

i²Cool is developing iPanit2.0 and please stay tuned!
