Project Overview
Oak Harbor Hillside Res
End Use: Private Residental
Why SIPs?: We absolutely "rock it" when it comes to energy use per square foot, and SIPS are a key part of our strategy.
Benefit of SIPs: SIPs made it possible for a faster build time, tighter building envelope, better indoor air quality, better insulation values, and vapor-proof (condensation-free) wall and roof assemblies.
Innovative Design: We tucked this daylight-basement home into the side of a hill, using ICFs for the below-grade foundation walls, and SIPS for all else.
Certifications:
- US DOE Zero-Energy Ready
- EPA Indoor Plus
- Energy Star
HERS Rating: 49 without PV
Blower Door Test: .47 ACH 50
Energy Use Intensity: With a 16˚F design degree day, this 2572 s/f home requires just 20,254 btuh, for an energy-use intensity of 7.874 btuh per square foot.
HVAC: HVAC system is a Daikin Ductless heat pump, COP 3.31
Energy-Saving Materials / Energy-Efficient Products or Design Features:
- The Ang home used PlyGem HP3-Max windows, with an average U-value of .22.
- The ICF foundation features R-22.5 of insulation in the walls and R-20 rigid foam insulation under the slab.
- The main floor features a 3" concrete thermal mass slab over wood framing for heat retention from day to night. This feature alone will save up to 22% of the total heating load on an annual basis.
- 100% LED lighting
- Energy-Star Appliances
The building was oriented to optimize both passive and active solar systems - The roof was designed to hold up to 18kW of solar panels, though just 6.75kW would get it to zero energy, leaving enough additional capacity to power at least three electric cars for more than 12,000 miles per year each.
Solar Panels: Solar panels have been engineered into the project, and infrastructure is in place, but installation has not happened yet.
Client Comment: "SIPS gets it done, every time.'
