Urban Heat Island: Not a Black and White Issue

The author of this article refutes comments by the U.S. Department of Energy (DOE) suggesting that reflective pavements will lessen the urban heat island (UHI) effects in cities in ways similar to reflective roofs. Pavement color, he writes, is not a good indicator of potential impact on overall UHI. He notes that the Centers for Disease Control recommends against the use of reflective pavements in schoolyards due to increased glare and increased radiation scatter. He points out that roofs and pavements do not affect urban heat in similar ways. He suggests instead that pavement design can assist in reducing potential urban summertime heat, and that open-graded asphalt pavements have been effective in reducing pavement surface temperatures. Open-graded pavement also improves the quality of storm water runoff and reduces highway noise.
