An equal access/equal opportunity university, Maintained by Office of Strategic Communications. Although highly desirable, full daytime sub-ambient radiative cooling in commercial-like single-layer particle-matrix paints has not been achieved. This white paint is the result of six years of research building on attempts going back to the 1970s to develop radiative cooling paint as a feasible alternative to traditional air conditioners. Tour Barbara Walters' Former NYC Apartment. By keeping surfaces cool and reducing the use of air conditioners, which are typically powered by electricity, the paint may help decrease the burning of fossil fuels. The worlds whitest paint seen in this years edition of Guinness World Records and The Late Show With Stephen Colbert keeps surfaces so cool that it could reduce the need for air conditioning. "The paint is not available on the market yet," Xiulin Ruan, the lead researcher on the project, told USA TODAY Thursday. For further discussion on this intellectual property, please contact D.H.R. It could help keep buildings cool, potentially replacing energy-intensive air . Painting roofs white isn't a new thingcities and cultures around the world have been using that technique to keep buildings comfortably cool for centuries. The original paint needed to be in a layer that was at least 400 microns thick. Trouble with this page? Purdue researchers introduce ultra-white paint, which is the coolest This paint is basically creating free air conditioning by reflecting that sunlight and offsetting those heat gains from inside your house, said Joseph Peoples, a Purdue Ph.D. student in mechanical engineering and a co-author of the work. Commercial white paints are cooler than the other, darker-colored paints, but they are still warmer than the ambient or surrounding temperature, Ruan says. We turned to interior designers, architects, and folks elsewhere in the sustainable design space to hear how they would use the product in their projects and with their clients. See how Purdue never stops in the persistent pursuit of the next giant leap athttps://purdue.edu/. The key was barium sulfate, which allowed the paint to . Journalists visiting campus should follow visitor health guidelines. Developing this paint formulation wasn't easy. Radiative cooling is a passive cooling technology that acts by reflecting sunlight and emitting radiation in the sky window. Our paint only absorbs 1.9 percent of the sunlight, whereas commercial paint absorbs 10 to 20 percent of sunlight, says Xiulin Ruan, a Purdue mechanical engineering professor and one of the studys co-authors. The research was performed at Purdues FLEX Lab and Ray W. Herrick Laboratories and the Birck Nanotechnology Center of Purdues Discovery Park. Price shouldn't be a problem, Ruan says, with a gallon costing almost exactly the same as a gallon of ordinary paint right now, approximately $30 to $40 per gallon.
