Smart windows out on the market
Smart windows save energy and block out dazzling sunlight by adjusting the amount of light let in. This innovation from Uppsala has been refined for a number of years and the production of commercial deliveries is now under way at manufacturer ChromoGenics.
It looks like a normal window but between two layers of glass is a thin-film laminate which regulates how much light and radiant heat is allowed through the window pane. The laminate changes its optical properties and can change from transparent to dark.When the window is dark it lets in less solar energy and this makes it cheaper to cool the air inside.
