This Paint Reflects Sunlight On Streets To Help Keep Cities Cool

By

Different colored roads could have a significant impact on how much heat is absorbed during the summer months. For example, Los Angeles, California, will be testing out a grey “cool pavement” called CoolSeal that will likely reflect more of the sunlight and thus decrease the urban heat island that many metropolitan areas deal with. Should it be successful, it could see widespread adoption across the country.

The urban heat island (UHI) is an area in the city that’s much warmer than its surroundings. This is generated from the environment (such as extremely warm weather) and human modification. As cities get bigger, they’ll likely boost their UHI. Increasing temperature within cities creates major problems, such as impacting air and water quality with more pollutants. This affects not only our health, but the environment, as well.
