| Abstract | In this study, the development of electrochromic (EC) glazing is described. EC devices combine optimum dynamic control of the solar radiation penetrating into buildings with a high degree of thermal insulation. The optimisation of the EC devices included the deposition of the materials (electrochromic oxide WO3, ion storage layer CeO2 or V2O5), the selection of suitable transparent conductors (K-GlassTM) and the fabrication of polymer electrolytes based on lithium salts. Electrochromic glazing prototypes with dimensions up to 40 cm ? 40 cm have been fabricated using vacuum techniques and chemical methods. The prototypes exhibit excellent optical and thermal performance, with a contrast ratio up to 1:32 (visible dynamic transmittance range Tlum, bleached=63% and Tlum, colored=2%) and coloration efficiency up to 92 cm2/C. Their durability in relation to real working environmental conditions has been assessed through indoor and outdoor testing. Such a glazing can be used in building applications to improve occupant thermal comfort, contribute to a reduction in space heating and cooling loads and allow for increased areas of fenestration thereby reducing artificial lighting loads. These factors reduce the energy demand for the building and therefore contribute to the reduction of carbon dioxide emissions. |
