U.S. Researchers Develop Passive Cooling Technologies to Reduce Urban Heat and Energy Use
Researchers across multiple U.S. institutions have developed innovative passive cooling technologies to reduce urban heat and energy use. These include a film cooling metal roofs by over 40°F in Houston, a pigment-free paint lowering surface temperatures by 6°C in Arizona, and a temperature-adaptive coating using vanadium dioxide that adjusts to seasonal changes. Additionally, modeling in Chicago showed white roofs can reduce city temperatures by nearly 2°C and cut cooling energy demand by over 16%. These advances aim to improve urban sustainability and public health amid rising heat risks.
