Smart Windows to save energy

Bijschrift toevoegen

RavenBrick is producing new window coatings that automatically adjust to control solar gain through windows. The Raven Windows are made with a special nanomaterial coating which makes the window responsive to outdoor temperature. This intelligent window automatically blocks solar heat when the outside temperature is too hot, while delivering solar heat inside when the outside temperature is cold.

The Raven Window material is a thermo-reflective coating that is applied to the inside surface of the outer pane of glass in a double-glazed window assembly. The material is somewhat like glasses that darken when you step outside into brighter conditions. Although darker, the material is more thermally reflective, so that heat is kept out of the building during hotter times of year, but is transparent, and lets heat and light through when the temperature is colder. Better yet, unlike some other technologies, the transformation is automatic, and requires no electricity or controls.
