Net-Zero Buildings and Dynamic Glass

Nov. 27, 2018

Net-Zero building design is a critical part of transitioning to a lower-carbon built environment. While such buildings number in the thousands today, the market for net-zero buildings is growing fast, at nearly 40% CAGR out to 2021 by some reports. For those less familiar, net-zero building means constructing a building that will produce as much energy (typically site, not source energy) as it consumes on an annual basis. At a very basic level that means doing two things: designing a building that has very low energy consumption and produces energy on-site. Dramatically reducing consumption becomes especially challenging when you’re also trying to design with lots of glazing to provide daylighting and views. This is where dynamic glass comes into play.

More and more Net-Zero buildings are recognizing how important dynamic glazing is as they are forced to make a choice: reduce the glazed area to hit the needed EUI levels or utilize dynamic glazing. Since ample glazing is often a critical part of the design for many buildings it becomes an easy choice. When the energy modeling is done properly, customers see how dramatic the difference between standard and dynamic glazing can be for a building. As a testament to this, Penn State University conducted research which showed that a building with a 30% window-wall ratio using typical low-e glass would consume as much energy as building with a 50% window-wall ratio using dynamic glass.1

Recent Net-Zero projects which have selected SageGlass to help meet their goals include:
