SageGlass - A dynamic glazing that electronically tints to control the daylight and heat in buildings

SageGlass aims at providing an elegant and sustainable alternative to conventional buildings' facade solutions for architects and builders looking at solving solar control challenges without sacrificing aesthetics, energy-efficiency or comfort. SageGlass dynamically adapts its tint in response to the weather conditions and the building's needs, to manage the daylight and heat in a smart way. Spaces always benefit from daylight and a free access to views to outdoors, without suffering from glare nor overheating. This thus results in reducing the building's energy use and improving the occupants' comfort and well-being.
