Roxbury, MA
Passive House, 140 Centre Street
Scope/Solutions
Like all Placetailor projects, the Fort Hill Passive House is built with a focus on energy efficiency and sustainable building practices. SGH designed the structure for the five-unit, multifamily building.
The project includes the following passive strategies:
- Highly insulated and airtight enclosure with careful detailing to minimize thermal bridging
- Balanced continuous ventilation with energy recovery
- Efficient mechanical, electrical, and plumbing systems
- Hot water panels on roof for solar gain
SGH designed the wood-framed structure and highlights of our design include the following:
- Sustainably harvested wood
- Wood framing spaced at 24 in. o.c. to reduce material usage compared to typical 16 in. o.c. spacing
- Stud walls with interior and exterior stud walls, creating an interstitial space for continuous cellulose insulation between the planes
- Interior stud wall located inboard of the retaining wall, allowing for a thinner retaining wall and minimizing the volume of concrete
- Wood-framed, roof trusses with open webs, providing a cavity for continuous cellulose insulation
- Roof and floor sheathing that cantilevers over the interior stud wall, minimizing the thermal bridge to the exterior wall
- Use of foam glass isolators at structural bearing locations, reducing thermal losses through the structure

Additional Projects
Northeast
Twenty|20 at 20 Child Street
Leading the development at East Cambridge’s NorthPoint site, Twenty|20 brings 355 apartment units to the growing neighborhood. SGH consulted on the building enclosure design.
Northeast
The Lucas, 140 Shawmut Avenue
Preservation and renovation of the exterior walls, tower, and certain windows of the church and rectory led to a design that beautifully blends historical mass masonry with a modern addition and interiors. SGH consulted on the building enclosure design for the adaptive reuse project.
