SAGE Electrochromics, which was recently acquired to become a wholly owned subsidiary of Saint-Gobain of Paris, is demonstrating its newly developed advanced dynamic glass that it calls “SageGlass” at the 2013 BAU, the “World’s Leading Trade Fair for Architecture, Materials, Systems” in Munich.
SageGlass is electronically tintable to allow for modulation of light, glare, and solar heat gain. With the push of a button, or by of building automation systems or the proprietary SageClass control system, the glass can alter the solar heat gain and visible light transmission. Providing for efficient and flexible control of exterior light, SageGlass replaces blinds and motorized window shades that block light coming through windows, curtain walls, and skylights.
Using a patented technology, the glazing level of SageGlass tint is dynamically controllable from 2% to 62% of light transmittance while maintaining transparency so that outdoor views are unobstructed to maximize energy efficiency while improving the comfort and productivity of building occupants and increasing the value of the building.
According to a recent press release, SageGlass tint achieves this by managing “solar heat with a g value varying from 0.42 in its clearest state to 0.05 in the darkest state (values for a DGU with a Ug value of 1.1 W/m2.k).” The SageGlass dedicated automatic control system enables the tint to automatically adapt to outdoor luminance.
“BAU will be a terrific opportunity to showcase SageGlass’s impact on daylight and sun heat for the first time to the German market,” said SAGE SAINT-GOBAIN Europe, Director of Marketing and Sales, Kirk Ratzel.
