Researchers Develop Passive Cooling Coatings to Reduce Surface Temperatures
Researchers at the University of Illinois and Columbia University have developed innovative passive cooling coatings that reduce surface temperatures without electricity. Illinois' film lowered metal roof temperatures by over 40°F in Houston, tested ahead of the FIFA World Cup, while Columbia's pigment-free paint kept surfaces 6°C cooler than ambient air in Arizona's desert heat. Both technologies reflect sunlight and radiate heat, offering sustainable solutions to rising heat-related health risks in urban environments. These advancements remain in experimental or early deployment stages.
