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

Post-Hurricane Sandy Evaluations
On 29 October 2012, Hurricane Sandy made landfall along the eastern United States seaboard, bringing high winds and a tidal surge, and causing billions of dollars in damage to our built environment. Some of the worst damage was reported in the coastal areas of New York and New Jersey.

Watermark Kendall East at 250 Kendall Street
Watermark Kendall East brings an additional 144 apartments to a new residential complex, which also includes a 321-unit tower and parking structure constructed in an earlier phase. SGH consulted on the building enclosure.
