Heat Island Effect
The heat island effect is a temperature phenomenon in which heat-absorbing buildings, especially those with dark roofs and non-reflective surfaces, release heat absorbed from sunlight into the surrounding atmosphere. The resulting effect is an increase in outdoor air temperature of 2 to 8 degrees Fahrenheit in a specific area, or “island.” Increases in local air temperature caused by the heat island effect generally occur in urban areas and centers where many buildings with dark roofs are concentrated in a small area.

Some ways to combat the heat island effect include installing green roofs, using light-colored roofing and paving materials that do not absorb heat, and planting trees and vegetation.
