SageGlass Electronically Tintable Glazing
SAGE Electrochromics, Inc.
SAGE Electrochromics manufactures SageGlass, an electronically tintable exterior glazing that blocks solar heat gain while providing glare control and preserving views. SageGlass incorporates durable thin-film ceramic coatings and uses 0.28 W/ft2 to switch the glass from clear to tinted state and 0.1 W/ft2 to maintain a darkened state. Used with typical clear glass to fabricate an insulated unit, the tinting reduces the visible transmittance (Tvis) from 60% to 1%, while reducing the solar heat gain coefficient (SHGC) from 0.41 to 0.09. The company's triple-pane (Tvis 52% vs. 3%; SHGC 0.38 vs. 0.06), argon-filled and krypton-filled glazings have center-of-glass winter U-factors as low as 0.14 (R-7.1) and 0.12 (R-8.3), respectively. SageGlass can also come with a technology called LightZone, which enables one pane of glass to be tinted to different levels in three sections. SAGE is partnering with window, skylight, and curtainwall manufacturers to produce commercial and residential products that can help save energy while improving occupant comfort and control.
