Citibank Hong Kong

In its publicly released "2025 Sustainable Development Strategy", Hong Kong Citigroup has clearly stated that it will rapidly promote the transition to a low-carbon economy and has taken a series of green measures. In addition to using solar panels on the rooftop of Citibank Tower in Hong Kong, the 1200 square meter rooftop of the building is also fully coated with iPain cooling coating. After actual testing, the surface temperature decreased by 25.7 ℃ after coating, effectively slowing down the thermal gain of solar panels and improving power generation efficiency. Indoors, it can cool down by 2-6 ℃. For every 1 ℃ decrease, the energy efficiency of indoor air conditioning increases by 6% to 8%, improving the overall building energy efficiency of Citibank Tower.

The core product of Chuangleng Technology, iPain, is a non electric cooling coating that integrates principles of optics, thermodynamics, and materials science. It uses cutting-edge nanomaterials to achieve efficient sunlight reflection and mid infrared radiation, effectively controlling the absorption and release of heat, and achieving zero energy cooling without the need for external power sources and refrigerants. The porous structure formed by the combination of polymer and inorganic particles exhibits optimized optical and thermal properties, with a solar reflectance and mid infrared radiation rate of up to 95%, breaking through the technical bottleneck of traditional thermal insulation coatings. Chuangleng Technology's non electric refrigeration coating iPain has launched customized solutions for key fields such as construction, chemical industry, power communication, new energy, logistics, grain storage, and photovoltaics, helping various industries achieve green transformation.
