SageGlass® is a variable tinting glass that can be controlled to allow the building to react to the outdoor environment, and can be fully automated.

In the clearest state, SageGlass is a very high performance IGU, with a .41 Solar Heat Gain Coefficient (SHGC) and a 60% Visible Light Transmission (VLT). In it's fully tinted state, the performance is .09 SHGC and a 1% VLT, with two intermediate points in between. SO, SageGlass blocks all of the entering the building. 2,000 square feet of SageGlass will consume the electricity of a 60-watt incandescent light bulb.

SageGlass is a sun problem solution that has no moving parts, and nothing ever to maintain. Building owners spend a lot of money on traditional means to deal with a sun problem, including static low-e glass, exterior sun control devices, blinds an/or shades, increased artificial lighting, and larger HVAC systems. Glare and heat can even dictate how the furniture is placed in a space, and where we place our flat screens. In most cases, when we can get involved early into the design of a project, SageGlass will prove to be cost neutral, often less. to the multi-component systems. More importantly, we retain the reason the glass is there in the first place, natural daylighting and a view and connection to the outdoors for the occupants.
