Architecture Puzzler #117
Question
An "urban heat island" is a term describing a highly developed urban area that is warmer than the surrounding countryside. This phenomenon was noted during the Summer Olympics in Atlanta, Georgia. Atlanta was how much hotter than the surrounding countryside?
Answer
Atlanta was 12 degrees Fahrenheit (6.6 degrees Centigrade) warmer than the surrounding countryside. In order to reduce the "urban heat island" effect, the State of Georgia enacted the "White Roof Amendment" requiring additional insulation for roofing systems whose surfaces do not have a test value of 75 percent or more for both solar reflectance and emissivity.
