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

Macallen Building Condominiums
The Macallen Building is the second phase of a 270-unit residential development in South Boston. The building contains three parking levels, a 20,000 sq ft elevated green space, and 140 units spread over an additional eleven levels. SGH was the structural engineer of record for the project.

Billiou-Stillwell-Perine House
The earliest section of the Billiou-Stillwell-Perine House was constructed in the early 1660s at a time when Staten Island was part of the Dutch colony known as New Netherland. SGH performed a condition assessment of the structure, contributed to the report, and recommended repairs.
