Study: The temperature in Riyadh can be reduced by 4.5 degrees. Light-reflecting coatings on building roofs and irrigated green spaces reduce the temperature in the city.
This is the first of its kind to examine the benefits of applying innovative heat-reducing technologies in hot cities. In the Saudi capital, Riyadh, maximum temperatures exceed 50 degrees Celsius during the summer, making it one of the hottest cities in the world. The combination of rapid urbanization and climate change is raising temperatures, with resulting increases in energy consumption.
