Old Colony Phases 4/5 Attains Passive House Certification

Cranshaw Construction is proud that The Anne M. Lynch Homes at Old Colony Phases 4 and 5 in South Boston have officially received Passive House certification from Phius (Passive House Institute US).

Cranshaw has been part of the ongoing redevelopment of the Boston Housing Authority’s Old Colony public housing community, including Phase 3A and now Phases 4 and 5, replacing outdated buildings with modern, energy-efficient, and healthy homes for residents. Phases 4 and 5 encompass newly constructed buildings containing 208 affordable apartments for new and returning residents.

Passive House is a rigorous building standard focused on creating structures that achieve exceptional energy efficiency, comfort, and indoor air quality. Buildings designed to meet Passive House standards use significantly less energy for heating and cooling compared to conventional construction, thanks to superior insulation, airtightness, and high-performance windows and systems. For residents, this translates into lower utility costs, improved comfort, and a healthier living environment.

In Cranshaw’s role, we worked closely with project partners from design through construction to integrate energy-efficient systems, optimize the building envelope, and monitor quality throughout construction.

Congratulations to Beacon Communities as well as their design and consultant team: The Architectural Team (TAT), New Ecology, Inc., Peterson Engineering, WaypointKLA, and McPhail Associates.

This achievement underscores Cranshaw’s ongoing commitment to building high-performance, environmentally responsible spaces that support high-quality affordable housing.
