The first CHBA Net-Zero Renovation in BC.

About this home

This Birken home is the first CHBA labeled Net Zero Renovation in BC, and the second in all of Canada! The use of energy efficient materials, construction practices that utilize the best practices of building science, and effective financing tools are required to successfully achieve affordable and cost-effective Net Zero Renovations.

This home does just that with a number of high-performance key features that promote sustainability while remaining cost-efficient. This development is built with EuroLine triple-glazed windows with a USI ranging from 0.79 to 0.85, and a SHGC ranging from 0.15 to 0.16, providing shading that prevents overheating during the summer months. All Net Zero homes are extremely airtight and well-insulated, and this Birken home is no exception, with 2×4 @ 16 26” O.C R14 Batt, 2” Neopor rigid foam above grade walls in addition to 8” concrete with R12 2lb spray foam foundation walls.

The home envelope is 34% better than an NRCan reference house, providing you with optimal insulation while prioritizing cost-efficiency and comfort. The airtightness of the home pre-renovation was 7.0 ACH (Air Changes per Hour), compared to 1.34 ACH post-renovation. Other sources of renewable energy include a 10.3 kW PV system, and high-performance heating and water systems that are all electric. This stunning development was built to last, maximizing on technology that promotes sustainable and renewable energy sources ensuring durability and peace of mind.
