Paper Abstract

The application of electrochromic materials to the control of radiant solar energy transfer into building interiors is potentially useful for reducing energy consumption. Electrochromic materials would be used as multilayer window glazings that act as variable absorptance or variable reflectance light apertures. In this article a variety of electrochromic window structures, which demonstrate variable aperture operation in both the absorptance and reflectance mode, are presented. The electrochromic and optical properties of several mate-rials, including Mo03 and Ir02, have been investigated. A high near infrared reflectance, >55%, has been measured in crystalline W03 after Li insertion. The performance of a variable aperture W03 electrochromic window has been demonstrated by calculating the spectral solar throughput in various stages of operation.
