Boston’s Financial District will soon welcome the groundbreaking Winthrop Center, a year-round, mixed-use gathering space with a suite of impressive eco-friendly credentials. Designed by Handel Architects in partnership with MIT professors, Winthrop Center will not only target LEED certifications and a WELL certification but is also expected to become the largest Passive House-certified office building in the world. The project takes COVID-19-era concerns into account with its emphasis on healthier indoor environments and will include features such as MERV 15 filtration and airtight workspaces that minimize moisture transfer and entry of contaminants.

Slated for completion in 2022, the 691-foot-tall Winthrop Center will offer over 1.8 million square feet of mixed-use programming, including 812,000 square feet of Global Class A office space, 572,000 square feet of residential space (with 321 luxury residences) and the renovation of the existing One Winthrop Square into a grand new public space with year-round programming. At the heart of the project is The Connector, a ground-floor urban “living room” wrapped in 50-foot-tall structural glass walls that opens up to Winthrop Square and Federal Street to directly engage the pedestrian realm. The gathering space will be open to the public throughout all seasons from morning to night.

To meet LEED standards, the Winthrop Center will feature a high-performance exterior envelope to minimize solar heat gain while maximizing access to natural light. The curtainwall design will be constructed with triple-glazed insulated glass windows with glass spandrel panels for an average of R-30. Responsible water usage strategies, recycling, sustainable materials use and sourcing as well as energy-efficient building operations will also be incorporated. The office and public spaces will target LEED Platinum certifications, while the building’s residential component will be designed to LEED Gold standards.

The office spaces will also target WELL Gold certification and provide occupants with a healthy indoor environment through elements such as improved air and water quality, healthier food options, encouragement of physical activity and enhanced natural lighting throughout. Office spaces are designed for flexibility to promote collaboration and connections.
