The study looked at how the shape and layout of buildings and green spaces in cities affect how hot it gets in different parts of the city. Using high-resolution satellite data, researchers found that tall buildings spread out can help lower temperatures, while trees and green areas help cool things down too. Residential areas tend to be the hottest, while commercial and industrial zones are even hotter. Overall, the shape of buildings and greenery in a city can make a big difference in how hot it gets during the day in the summer.
