The University of Technology in Sydney, Australia, has created a new roof material made up of layers of specialized plastics over a layer of silver. It reflects the sun's rays, staying 50 degrees cooler than current white roofs. "Cool roofing reduces the severity of the urban heat island problem in towns and cities and helps eliminate peak power demand problems from the operation of many air conditioners," said Geoff Smith, co-author of the research.
