RavenBrick's window filters could cut building's energy use by 40%

Abstract:
Over the past three years, a Denver startup company has developed, tested and patented a filter for windows that is expected to reduce energy consumption in buildings by 40 percent.

RavenBrick's thermoreflective filters use nanotechnology to transition from a transparent to a reflective state in response to changes in the outside temperature. The transition allows a building to use the sun as a source of free heat on cold days and block solar heat effectively on hot days.

"We want to harness the outside temperature," said Alex Burney, the company's chief executive. "That's the path to energy independence."
