In case you missed it, here is a short video of the Butterwick crew working with a crane operator to install pre-built walls on the existing home.
Even though we aren't done, the home has completely transformed.
The pre-fabricated panels, which included windows, doors, and house wrap, have been insulated. The rainscreen has been installed, which the siding will be installed over, leaving a cavity for moisture to easily drain out of the building's exterior. The whole house is now airtight. A new roof has been built right on top of the old one, insulated, sheathed and shingled.
Crews have built the new front veranda (a very apropos addition for this mature Highlands #yeg neighbourhood).
Next step - Siding!
When the project is done, this home will be 70 to 80% more efficient and net-zero ready. This means that it will be able to get all of its energy needs from renewables, like solar.
We are so looking forward to sharing what we learned about this project, the first energiesprong-inspired deep retrofit of a single-family home in North America.
Thank you to Smart Sustainable Resilient Infrastructure Association for helping fund this project.
