It is estimated that 10 percent of all energy used in buildings in the US is consumed through the windows, it is worth building owners about $ 50 billion annually. However, the high cost of replacement windows, or modifying their energy-saving coating is a major deterrent. The Department of Energy (DOE) US National Laboratory. Lawrence Berkeley (Berkeley Lab) seek to resolve this problem through creative chemistry - polymer temperature-reflective coating applied which is ten times cheaper than existing methods.
"The idea is that instead of hiring expensive contractors, the homeowner will be able to buy at your local hardware store and apply a coating of its own", - said Lauren Veyntkamp Berkeley lab worker. "Covering selectively reflects the infrared spectrum of
One of the remaining technical problem is to improve the accuracy of the material so that the light is strongly reflected infrared and visible light was not scattered and no haze. This will allow the coating to reflect most of the solar energy, reducing the amount of heat flowing into the building, while still remaining transparent. Using cutting-edge experiments in its window, Berkeley Lab will test and analyze the properties of the coating.
"We did not need to use a particularly cost-effective materials and raw materials for production, when we did this cover in the laboratory, but now will strive for efficiency," - said Veyntkamp. "Initially this was a research project with a chemical synthetic polymer, but the presence of a great application prospects encourages us to do it in the best way the Berkeley lab."
