Located around a natural setting next to the Fort Davis Park in Washington D.C., the Francis A. Gregory Neighborhood Library was designed by the architectural practice of Adjaye Associates incorporating the Guardian SunGuard 68 high performance architectural glass along with the Silver 20 in order to provide the best light transmission and best views of the park.
These materials are used throughout the project covering all four sides of the library and stretching all the way to the roof supporting it. From the exterior the walls look like a chess board with alternating panels that are either reflective or transparent and this pattern was created to offer a balance between the low-E and the double insulated panels.
Aside from the aspect, the use of these materials also increases the eco-friendliness of the building, since they improve its energy performance due to the reduced solar heat gain. This feature allowed the project to receive a LEED Silver rating.
