RavenWindow – the latest in energy efficient windows

Raven Window 2

In the United States, buildings consume approximately 39% of the country’s energy and 68% of its electricity. To help reduce this RavenBrick have come up with RavenWindow, a “smart window” that automatically changes to reduce or increase the amount of light that passes through it depending on the temperature.

RavenWindow can increase a building’s energy efficiency up to 40%, instantly changing to a dark tint on hot sunny days or shifting to a neutral, transparent view on cooler days to let solar heat through. Using no electricity, wiring or control systems, these windows will reduce both heating and cooling costs, bring more use of natural light to the building and add a comfort factor for the people inside.

Thermoreflective filters along with nanotechnology help create the easy transitions between dark and light. This cost-effective, easy-to-install window system requires almost no maintenance and can be installed in any building. Though not yet commercially available, they’re currently being installed at the Department of Energy’s National Renewable Energy Laboratory (NREL) in Golden, Colorado. No word yet as to what the price will be but with potential savings like this, it seems like these will become the windows of choice.

RavenWindow smart windows an integral part of a building’s energy conservation strategy. Thanks to a breakthrough in smart window technology, RavenWindow automatically adapts to outside temperatures to reduce the need for air conditioning and heat. On hot days RavenWindow reflects the sun’s light and heat away from the building, keeping indoor temperatures cooler.
