Keeping a large building cool during hot summer months is no easy task. In addition to soaking up warmth from outside, building dwellers also have to contend with heat generated from within. It\u2019s a combination that often forces air conditioning units to work overtime.<\/p>\n

Researchers from Stanford University have come up with a new solution to help keep occupants from roasting during the summer \u2013 an extremely thin coating that works by reflecting up to 97 percent of sunlight while simultaneously radiating heat from inside the building.<\/p>\n

It\u2019s a technique that the researchers have dubbed photonic radiative cooling.<\/p>\n

\"\"<\/a><\/p>\n

The material they created consists of eight layers and is collectively just 1.8 micros thick (that\u2019s thinner than the thinnest sheet of aluminum foil). Specifically, it\u2019s made of seven layers of silicon dioxide and hafnium oxide on top of a thin layer of silver.<\/p>\n

The technology certainly sounds promising although it doesn\u2019t appear to be close to commercial use just yet.<\/p>\n

The first problem is figuring out how to transfer a building\u2019s internal heat to the exterior coating. Once it gets there, the material can expel it but getting it there is the first hurdle.<\/p>\n

The researchers\u2019 second issue is scaling. Their existing prototype is the size of a personal pizza \u2013 or in other words, nowhere near as large as it needs to be to do its job efficiently in a real-world application. The good news here is that existing production facilities are capable of scaling it up to desired sizes.<\/p>\n
