Electrochromic glass

Edit Hook

Smart-windows possess variable tinting based on electronically stimulated pigment. They can provide substantial energy savings by reducing cooling/heating costs.

Key Differentiators

Electronically managed windows are capable of manual control, pre-set settings, and automated schedules.

Biomimicry Story

Passive pigmentation is a strategy employed throughout nature, for instance in cephalopods and many lizard species. Passive thermoregulation is an even more pervasive strategy that is present in different phylogenetic kingdoms. The electrochromic system is similar to unconscious nervous system regulation of pigment systems in many animals.

Challenges Solved

Buildings that can take advantage of natural sunlight can save on lighting and improve the quality of spaces for occupants. However, light also brings heat, necessitating cooling systems to maintain comfortable temperatures. Smart-windows can mitigate these two competing issues. SageGlass has "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."[U.S. Department of Energy’s (DOE) Lawrence Berkeley National Laboratory (LBNL)]
