| Located on Vancouver Island in the beautiful Comox Valley, Integra is one of the premier home builders in the area. For this particular Row Home Project, the original target was the minimum required in the Crown Isle subdivision at Step Code 3. However, with help from our local Senior Energy Advisor Richard Bice, Integra decided to push forward and go beyond the minimum. Congratulations, the project ended up achieving Step Code 5 compliance!
Building characteristics include:
- Windows: High performance double glazed LowE glass with Argon gas

- Water Heating: Natural Gas condensing tankless on demand
- Ventilation: HRV 78% SRE @ 0 degree C
- Air Tightness: 1.0 ACH
- Window to wall ratio: 14.9%
- Air Barrier: exterior weather barrier for wall + poly vapour barrier for attic
- Insulation
- R-40 attic blown-in fiberglass insulation
- Above grade wall: 2×6 @ 16” o/c R-20 Batt
- Foundation: 8” concrete, 3” R-12 EPS
Builder: Integra Homes
Designer: D. Bell Designs – (darin.bell@shaw.ca)
This conventional build is an great example of how, simple geometry, low window-to-wall ratio, and excellent attention to air tightness, can achieve the higher levels of the BC Energy Step Code.
Air tightness targets can be very challenging for Row homes due to air leakage between the units. The common wall is typically the failure point, and builders struggle to detail the air barrier between the units. Integra however, has figured it out.
