SageGlass electrochromic glass is a sustainable solution that allows building owners and architects to solve solar-control challenges without sacrificing aesthetics.

A building can be designed to take advantage of natural daylight without compromising the connection to the outdoors, making dynamic a great fit for projects aiming to achieve sustainability certifications. By blocking sunlight on hot days and harnessing the sun’s energy on cold days, SageGlass solutions dramatically reduce energy demand and the need for HVAC, while increasing occupant comfort and well-being.


Buildings and construction together account for 36 percent of global final energy use and 39 percent of energy-related carbon dioxide (CO2) emissions when upstream power generation is included, according to the UN Environment and the International Energy Agency in their Global Status Report 2017.

Because SageGlass dynamic glass tints intelligently based on the seasons and needs, it brings significant energy savings over the course of a building’s lifecycle.

In addition to reducing the up-front material costs of shading systems, dynamic glass can also help reduce building operating costs. It reduces overall energy loads by an average of 20 percent and peak energy demand by up to 26 percent over a building’s lifecycle1.


In an age when environmental responsibility is expected, SageGlass can help you earn a wide range of credits towards green building certifications, such as LEED, BREEAM, WELL, LBC, Estidama, HQE and more.

SageGlass has a third-party verified Environmental Product Declaration (EPD), as well as a declare label, to provide architects, owners and specifiers with transparency documentation on the life-cycle environmental impact of the product. Material transparency is vital for reaching new sustainability requirements, and this EPD will make it even easier.

The EPD also helps SageGlass evaluate its own environmental impact. As part of Saint-Gobain, we use Life Cycle Assessments (LCAs) as a critical element of our eco-innovation process to identify impact-reduction opportunities at every stage of the lifecycle and quantify those reductions for improved and second-generation products.

Energy lost through conventional windows accounts for approximately 30 percent of heating and cooling energy, according to the U.S. Department of Energy. Not with SageGlass electrochromic glass. By adapting to external conditions, SageGlass minimizes energy use by reducing heating loads in winter, air conditioning in summer, and electrical lighting all year long.

Conventional windows require blinds and shades to offset the negative effects of the sun. SageGlass eliminates the need for separate solar shading systems — and the environmental impact of manufacturing, transporting, and cleaning them.
