Vacuum insulated energy-efficient windows. This project aims to develop large vacuum insulated windows with higher insulation performance than triple glazing, the best currently available, by toughening glass to increase its strength, flatness and safety. Higher performance windows reduce energy wastage in the developed world, and vacuum glazing’s thin profile means they can be retrofitted into buildings immediately, without the delay of replacing building stock. The anticipated outcome is a major reduction in energy use for climate control in buildings, a large and rapidly growing energy sector that climate change makes unsustainable; and rapid economic, social and environmental benefits through sustainable climate control in cities.Read moreRead less
