SageGlass is ideal for buildings where sustainability is a goal. It controls the sunlight and heat that enter a building, providing great thermal efficiency. It also means buildings can use smaller, more efficient HVAC systems, dramatically reducing energy consumption.


The US Department of Energy includes electrochromic windows like SageGlass in its roadmap to achieving zero-energy buildings. The DOE’s Lawrence Berkeley National Laboratory, which has been evaluating SageGlass for years,  considers electrochromic glazing to be the next major advance in energy-efficient technology. Researchers at the DOE’s National Renewable Energy Laboratory have said that full deployment of dynamic, highly insulating glazing can save up to five percent of the US energy budget. That’s equivalent to over 160 gigawatts of electricity generated annually by fossil fuels. Such savings could reduce CO2 emissions by 300 million metric tons.


SageGlass is a smarter, more elegant solution than sun controls such as mechanized window shades, blinds and louvers.


These add-ons result in a high carbon footprint when you factor in all the materials, transportation and operational energy they consume – a particularly big concern if you’re striving for sustainable construction. SageGlass also nearly eliminates the fading and damage caused by the sun, so you don’t need to replace interior furnishings as often, which saves resources.And at the end of its long life, SageGlass can be disposed of safely like any coated glass product (such as low-e).

More than 30% of a building’s energy goes out the window, literally. Not with SageGlass. By embracing sunlight when it’s cool outside and blocking it when it’s hot, SageGlass minimizes energy use and other expenses associated with operating a building. The US Department of Energy estimates that electronically tintable window systems are capable of providing up to:

  • a 20% savings in operating costs
  • a 24% reduction in peak demand
  • a 25% decrease in the size of HVAC systems


In fact, the National Renewable Energy Laboratory (NREL) says that if all buildings used products like SageGlass, we could save about 5% of the nation’s total energy budget each year. That’s like saving more than 160 gigawatts of electricity from fossil fuel-burning plants.


SageGlass — the industry’s first sustainable glazing solution that doesn’t compromise the view to the outdoors.
