High Quality Content by WIKIPEDIA articles! SAGE Electrochromics, Inc. is a specialized window glass developer based in Faribault, Minnesota. The company develops electronically tintable smart glass (also called electrochromic glass or dynamic glass), for use in building windows and skylights, that can be switched from clear to darkly tinted at the click of a button, or programmed to respond to changing sunlight and heat conditions. According to the U.S. Department of Energy’s (DOE) Lawrence Berkeley National Laboratory (LBNL), SAGE`s SageGlass technology "has the potential to reduce building heating and air conditioning equipment size by up to 25%, resulting in construction cost savings. SageGlass could also potentially reduce overall cooling loads for commercial buildings up to 20% by lowering peak power demand and may reduce lighting costs by up to 60% while providing building occupants with more natural daylight and greater comfort."
