Sub Lambda – Pacific Northwest National Laboratory
The technology under development is a potentially low-cost, passively switchable dynamic coating for windows that is based in part on subwavelength materials. As window temperature increases beyond a specified point, the coating will reversibly block infrared radiation, but not visible light. This allows for beneficial dynamic solar heating of a building accompanied by daylighting. If successful, this technology has the potential to provide significant energy savings for commercial and residential buildings. Through Energy I-Corps, the team hopes to better understand and characterize potential market uses for its technology.
