In many holiday resorts, the nearest examples being the Greek Islands and Bodrum, the houses are traditionally is white and local governments and laws prevent these buildings from being painted in other colors to protect the historical texture. Apparently ancient people also had a talent for color to live in cool cities.

Today, as temperatures continue to break records, new research suggests that cities can be made cooler. simple but very effective He offers a possible solution: painting the roofs of the houses white.

White roofs are important in combating heat

According to new research, our roofs paint white or covering with reflective layers is more effective at cooling cities than green roofs, street-level greenery and solar panels. The lead author of the study is UCL’s Bartlett Institute for Environment, Energy and Resources. Dr. Oscar Broussein his statement “Cool roofs are the best way to keep cities cool on extremely hot days” He stated that this was so.

Using a three-dimensional map of London and the surrounding area, researchers examined data from the hottest days of 2018. The study investigated temperature reduction in regions where cool white or reflective roofs were preferred. Average 1.2 degrees to 2 degrees it turned out that it was lower.

green roofs It was also revealed that it had no effect on temperatures, but caused a half-degree coolness during the hours when the highest temperatures were observed, while solar panels only provided a 0.3-degree cooler environment.
