New Colour Coating Addresses Urban Heat Islands | |
Researchers have unveiled a groundbreaking coating that combines aesthetics with functionality, designed to cool buildings and add vibrant colors to urban environments. This innovative technology could reduce reliance on energy-intensive air conditioning units, addressing both global warming and energy crises. The coating, developed by a team led by Dangyuan Lei from City University of Hong Kong, features a two-layered structure: a white base layer and a top layer enhanced with colored fluorescence. This combination not only provides a visually appealing finish but also cools surfaces by up to 1.5 °C below ambient temperatures. The study detailing this advancement was published in Advanced Optical Materials. Historically, white surfaces have been used in hot climates for their high solar reflectance, which helps keep buildings cool by reflecting sunlight. The new coating improves upon this by incorporating phosphors and silicon dioxide microspheres. Phosphors absorb sunlight and re-emit it as visible light in specific colors, maintaining high reflectance while providing vibrant hues. Silicon dioxide microspheres, significantly smaller than a pinhead, enhance solar reflectance and optimize the phosphors’ light emission efficiency.
