Explore the AERC case studies below to gain a better sense of how window attachment projects are used in commercial spaces and how they can improve energy efficiency, occupant comfort and more.

The 400 Market Street project utilized secondary glazing systems into the commercial office retrofit project in Philadelphia, PA. The 12-story building experienced significant energy savings as a result of the installed secondary glazing system. The whole building saw 25% building heating and cooling energy savings, and the perimeter offices of the building enjoyed an even more drastic improvement of 35-60%.

Genentech, a biotechnology company out of San Francisco, CA employed automated roller shades in their commercial office new construction project.The results of this installation led researchers to confirm that the shades helped to keep discomfort glare within the “imperceptible glare” range for occupants looking at computer monitors and that thermal conditions near the windows were “slightly cool to comfortable.”
