This forthcoming 691-foot, mixed-use tower in the heart of Boston contains 812,000 square feet of office space built to rigorous Passive House standards, setting a new global standard for building performance and energy conservation. Upon completion in 2023, Winthrop Center will be the largest Passive House office building in the world, modeling the most energy efficient solution for large scale buildings and leading the industry into the future.
The project team employed Steven Winter Associates, Inc. (SWA) and the Passive House Institute to assess the feasibility of achieving PH standards for a project of this scale. Because of the unique nature of this project, the Passive House Institute has agreed to use it as a PH Pilot Project intended to better understand and define the implications of building a high-rise office space to PH standards in a cold climate.
