Urban Heat Islands are a phenomenon in which urban ambient air temperatures are 2°F to 10°F (1°C to 6°C) hotter than nearby rural areas. These conditions are created through the use of dark colored roofing and paving materials, and the removal of trees and vegetation.

These elevated temperatures can impact communities by increasing peak energy demand, air conditioning costs, air pollution levels, and heat-related illness and mortality.

Fortunately, there are measures available to reduce the negative effects of heat islands.
