Urban heat islands (UHI) are metropolitan areas with higher temperatures than that in the surrounding environment. The higher temperatures consequence from greater absorption of solar energy by city materials for example asphalt and concrete, that have reduced albedos and higher heat capacities than People in the natural environment. An easy technique of counteracting the UHI effect is to paint buildings and roads white, and also to plant trees in the area.

Passive solar techniques consist of orienting a building to the Sun, selecting materials with favorable thermal mass or light-dispersing Houses, and designing Areas that naturally circulate air.
