Abstract

<abstract abstract-type="graphical" xml:lang="en" id="advs201500119-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A novel material open to warm air</bold> stays below ambient temperature under maximum solar intensities of mid‐summer. It is found to be 11 °C cooler than a commercial white cool roof nearby. A combination of specially chosen polymers and a silver thin film yields values near 100% for both solar reflectance, and thermal emittance at infrared wavelengths from 7.9 to 13 μm. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgj2n0t8hxs" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
