What is the term for the unnatural buildup of heat around buildings in urban areas?

The term that describes the unnatural buildup of heat around buildings in urban areas is known as the Heat Island Effect. This phenomenon occurs when urban regions experience higher temperatures than their rural surroundings, primarily due to human activities and alterations in land surfaces. Factors contributing to this effect include the concentration of buildings, asphalt, and concrete that absorb and retain heat, as well as the lack of vegetation that would otherwise provide cooling through shade and evapotranspiration.

The Heat Island Effect has significant implications for energy consumption, air quality, and overall urban climate, making it an important consideration in urban planning and environmental design. Understanding this effect is crucial for architects and designers aiming to create more sustainable and comfortable urban environments.
