Edmonton-based construction company, Butterwick Project, has started the first panelized deep retrofit of a single-family home in North America.

Logan Gilmour, a software developer from the gaming world, digitally captured the dimensions of this 1,950-square-foot 1940s home using a drone and his custom photogrammetry software.

For Edmonton homeowners Jim Sandercock and Melanie Harmsma, the deep retrofit is about reducing their family’s carbon footprint, role modelling climate action for their kids and reducing their energy costs as they prepare for retirement.

Jim, who is also chair of the Northern Alberta Institute of Technology’s Alternative Energy Program, said, “We need to electrify our buildings, but it is not practical when they are drafty with minimal insulation. It would take way too much solar and be a huge draw on the grid in the dead of winter.”

Digital capture on Sandercock’s home was done in 2021. Butterwick began onsite works in May 2022 and installed the panels in mid-June. When the retrofit is complete, Jim and Melanie’s home will use 70 to 80% less energy, making it net-zero ready.

The project is one of three single-family home deep retrofits Butterwick is doing in 2022. These retrofits are funded in part by Smart Sustainable Resilient Infrastructure Association.
