Abstract
An electrochromic glazing assembly is disclosed with reduced near-infrared radiation transmission and reduced ultraviolet (UV) radiation transmission. The assembly may include a pair of glass or other elements confining an electrochromic medium therebetween. Near-infrared reflective means are preferably included as at least one of a semitransparent, elemental thin metal film and a low emittance coating. Preferably, the assembly reflects at least about 30% of the solar energy for Air Mass 2 in the spectral region from about 800 nanometers to about 2500 nanometers.
