Citibank Hong Kong - Roof
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.
