Net Zero Duplex in Vancouver, BC – Lanefab Design / Build

We are excited to be working with one of Vancouver’s premier High Performance design/build construction companies Lanefab. This duplex will be CHBA Net Zero home labeled. That means the house will produce as much on-site renewal energy as it consumes on an annual basis.

Lanefab is an integrated design/build company that crafts custom homes and infill mini-homes (or “laneway houses”) with design quality & energy efficiency as core values.

Their projects are all unique; they are each built for a specific site and client and are consistently rated among Canada’s most energy efficient.

The home is utilizing the City of Vancouver’s Green Buildings policy for rezoning which allows for a floor area exclusion for Zero Emissions buildings (CHBA Net Zero, Passive House, Near Zero Emissions buildings), of 18% of the gross (or built) floor area in a two-family dwelling, or 16% in a one-family home.  This also allows for each side of the duplex to have secondary suites (4 units total).

Highlights of the home include:
Foundation slab:  9” R-36 EPS rigid under slab insulation
Foundation walls: effective R-24
Above grade walls: 2×6 + 2×4 R-31 batt – effective R-30
Ceilings: effective R-30
Windows: high performance triple glazed USI 0.90
Air barrier: Exterior taped sheathing
Air tightness: 1 ACH or lower (air changes per hour)
Heating system: Ductless mini-split air source heat pump and electric baseboards
Domestic hot water: Sanden Heat pump hot water tank
