Large area scaling of electrochromic glass samples can be reached only with so called "all solid states" types ,which show an inner adhesion. A very advantageous concept is the EC safety glass consisting of two coated K-glass panes which are laminated together with an ion-conducting PVB film. It has a safety glass construction and shows similar mechanical properties. Because of its inner adhesion scaling up to large areas becomes possible. The chosen electrochromic system consists of two complementary electrochromic layers, which enables important improvements in optical switching data compared to other systems. The electrochromic system works inside of the laminated double pane and is very resistant against environmental attacks. Construction as well as detailed optical switching behaviour and results of long term solar radiation control in facades tests were presented.
