Climate change and concrete structures have caused record high temperatures in cities, leading to a spike in heatstroke cases and exponentially increasing power consumption in recent years.
But researchers from the University of Pittsburgh have found a simple solution to deal with the complex issue. A coat of reflective paint on buildings and pavements, according to their study, could considerably lower temperature during the summer months.
The temperature in most cities could be two to four degrees Celsius higher than in the countryside. According to studies, trapped heat in buildings intensifies heatwaves to the extent that nighttime temperatures also remain high.
Los Angeles and Athens have paved roads and roofs with reflective paint to cool down air temperature. The measure has helped reduce the temperature in both cities, but glare and reflected light from painted surfaces are reportedly causing discomfort to pedestrians.
