Aluminum Foil-Like Material Acts as Cooling System for Buildings

According to Forbes, engineers at the University of Colorado Boulder have created a new material that works like an air conditioning system for structures—cooling rooftops with zero energy consumption.

The material, about the same thickness as aluminum foil, is rolled across the surface of a rooftop, reflecting incoming solar energy back into space while simultaneously purging its own heat. Adding to its appeal, the material is adaptable and cost-effective for use in large-scale residential and commercial applications, as it can be manufactured on rolls.

Xiaobo Yin, co-director of the research and an assistant professor at CU Boulder’s Department of Mechanical Engineering, says that by applying the material to the surface of a solar panel as much as one to two percent in solar efficiency can be recovered.

The breakthrough material was made possible by a three million dollar grant awarded by the US Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) that supports research in high-impact energy technologies.
