As the first commercial Passive House retrofit in the United States, the Glasswood project demonstrates the potential for high performance, low-load buildings to transform the energy efficiency, occupant experience, and marketability of existing commercial spaces, all at an affordable cost. The owners of this historic building set out to create a restaurant on the ground floor and office space on the second floor that would offer super-efficient energy performance and superior comfort while preserving the structure's historic character. Embedded in a walkable, transit-rich neighborhood, the project revolutionized the performance of the building while contributing to the vitality of its urban surroundings. Passive House design and construction was by Hammer & Hand, with architectural design by Scott | Edwards Architecture.
