Scope | Solutions


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
