Narrator: This is Science Today. A team of scientists at the Lawrence Berkeley National Laboratory have been testing and evaluating a variety of cool-pavement coatings, using a portion of a temporary parking lot at the Berkeley Lab. Graduate student Benjamin Mandel, who is part of the Heat Island Group, says their goal is to combat urban heat island effects, in which dark surfaces reflect sunlight and cause a significant jump in temperature.
Mandel: So, the cool pavement showcase here at Berkeley Lab is intended more as a demonstration to promote awareness and consciousness about cool pavement products that are commercially available. At UC Davis, we've installed some more pavement samples that would be suitable for a city road and in a variety of different materials, so we can actually actively monitor those samples and get results and see how they fare and perform over time.
Narrator: Mandel says one encouraging development has been the support of cool pavement measures by the Leadership in Energy and Environmental Design, or LEED. For Science Today, I'm Larissa Branin.
