Net Zero Retreat

About this home:

This modest home, set above the Columbia River wetlands, was specifically designed and built to overcome a series of interrelated challenges:

  • take in the stunning north-facing views;
  • achieve net-zero-ready standard;
  • keep embodied carbon as low as possible;
  • and do it all on a very tight budget…
  • during the historic construction materials price spike and backlog of 2020/2021.

 

We did it! Find out below.

Benefits and Features

Energy-Efficiency and Sustainability Benefits:

  • Built to BC Energy Step Code 5 and Net Zero Ready standards, this home delivered energy-efficiency on a seriously tight budget.
  • Site built, extra thick walls keep this home cool in summer and warm in winter.
  • The home’s fresh air machine (aka Heat Recovery Ventilator) and air-tight construction proved their worth during the 2024 Bruce Mountain Wildfire that threatened Wilmer while billowing smoke for weeks. Inside, this home stayed safe, comfortable, and cool.
  • A single air source heat-pump keeps this home at a comfortable temperature year round. During periods of extreme cold, a small supplementary wood-stove provides a boost, and some mid-winter ambiance.
  • Even with an EV and all electric energy, the small rooftop solar array produces enough power to zero-out the energy demand on an annual basis.
  • We lowered the carbon footprint of the home by adding 40% fly-ash to the concrete and using  all wood construction.

Design Features:

  • The gospel of green-building says no windows on the north side, but we just couldn’t look away from the 180-views of the Rockies and Columbia Wetlands – so we broke the rules and put in a huge window! Our Integrated Design Process identified energy solutions and savings elsewhere in the home to offset the energy loss, saving the best view in the Valley.
  • Designed for age in place living, this bungalow is compact, easy to access, and has everything a person needs on one floor.
  • European tilt-and-turn windows and bedroom doors provide security, energy efficiency and style.
  • Custom sandblasting of the entry door provides a personal touch and privacy.
