The search for a solution to the Urban Heat Island effect

The scorching heat increases water use and energy consumption for powering cooling systems in cities, leading to more emissions. As a result, researchers have been trying to find effective yet affordable solutions to tackle the issue of impermeable surfaces of buildings and roads absorbing sunlight.

The heat trapped by infrastructure increases temperatures within city limits, a phenomenon called Urban Heat Island effect.

The gray infrastructure mitigation strategy involves modifying impermeable surfaces of walls, roofs, and pavements, to counter their conventional heating effect, said a study published in Nature Communications.

A coauthor of the study said, “It’s important for the health of the planet and its people that we find a way to mitigate the heat produced by urban infrastructure.”

Researchers are gathering data on reduction in electricity consumption, heatstroke cases, and hospitalization to ascertain the strategy’s benefits.
