Single Family Residential. Semiahmoo Net Positive is a "forever home" for a family retiring to the Pacific Northwest. Our clients were seeking a net zero home - one that would produce at least as much energy as it would consume.

Single Family Residential. Semiahmoo Net Positive is a "forever home" for a family retiring to the Pacific Northwest. Our clients were seeking a net zero home - one that would produce at least as much energy as it would consume. SIPs were the logical choice for creating the highly insulated, air-tight envelope needed to achieve net zero in the Pacific Northwest. SIPs always make for a more efficient build, in terms of saving time on labor during construction and saving energy for the client, once the home is ready to occupy. This home features:

  • A Tatami room, bringing an element of the Far East into this otherwise Western-style home. This will serve as a simple gathering space or a place for meditation.
  • An elevator to facilitate aging-in-place
  • A simple rectangular design to minimize exposed surface area
  • Orientation and window placement to optimize active and passive solar
  • Slab on grade with 4” foam under-slab insulation
  • Insulated concrete forms
  • Triple-pane windows
  • High-efficiency air-source mini-split heat pumps (5 heads) for heating/cooling
  • High-efficiency heat pump hot water heater
  • HERS rating of - 3 (positive energy, more than it uses)
  • Air leakage blower door test rating of 0.35
