Case Study


Murray Associates Architects
Project manager
Pennsylvania Housing Finance Agency


Individuals and families with special housing requirements can receive assistance with home purchase and rental finance via the Pennsylvania Housing Finance Agency (PHFA). In this capacity, they also promote sustainable design and construction techniques.


HFA initially planned for LEED certification, but at the conclusion of the design phase, they challenged the architect, Murray Associates, to pursue Passive House certification. The biggest issue with their current design was the extensively glass façade, which caused solar heat gain and may make Passive House certification impossible.


The architect discovered a solution in SageGlass, Saint-Gobain'ssmartglass. The electrochromic glass manages energy silently, gathering solar heat in the winter and restricting it in the summer to lessen the need for HVAC. It also contributes to the creation of a comfortable environment with plenty of natural light and uninterrupted views of the outdoors. Furthermore, the cost of incorporating SageGlass into the design was not significantly higher than that of normal glass with mechanical shades, especially when considering user advantages and simplicity of operation for the PHFA team and staff members.

We care about building better.





Client's Words:

"If we didn’t use dynamic glass, we would have had to offset the energy loss elsewhere, such as adding solar panels or other energy saving elements to the design, and this building was right at the limit.”
