This one's a golden oldie - the Highlands project was one of the first energiesprong-inspired panelised residential retrofits in Canada. We FINALLY have a decent post-retrofit photo of the finished product. Check out the progression and then read the case study. buff.ly/qCVMzWW

Just posted a new case study from Heidi Mack, who lovingly deconstructed and rebuilt The Unhurried House—an 1871 farmhouse on Wolfe Island—into a #netzeroready home. Her slow, intentional approach embraced reuse, resilience, and hands-on learning. Full story here: buff.ly/t6cwt3w

🧥 New "jacket" for a 1960s bungalow 🏠

This #deepretrofit cut energy use by over 69% by wrapping the home in a high-performance building envelope.

Now draft-free, more comfortable, and one heat pump away from #netzero.

Come to Calgary with us!

Retrofit Canada's Peter Amerongen will present at the @albertaecotrust.bsky.social Environmental Gathering. The event's agenda is chock-full (or low-carbon-dense-packed-cellulose-insulation-full!) of other fantastic sessions.

@godostoyke.bsky.social used a modified Larsen truss to limit thermal bridging and hold 8" of compressed cellulose in this advanced envelope system. The innovation was essential to this #deepretrofit that made a 1971 bi-level home #netzero.

It was bound to happen! We've finally made it to the West Coast with this case study. The Fernwood #deepretrofit transformed a 1912 home into a net-positive energy residence with full electrification, enhanced insulation, and solar panels.

#netzero

Our newest case study comes to us from Manitoba's @suncertified.bsky.social . The Full Monty, an envelope-first, #netzero ready #deepretrofit guided by Passive House principles, cut the home's annual energy consumption by 70 per cent.

Another #deepretrofit case study!

The builder wrapped the home in continuous air and thermal barriers using a prairie technique called a chainsaw retrofit. With electrified mechanical and solar, the home's annual consumption dropped from 141 GJ to just 33.

This was the first #deepretrofit case study we published way back in 2020. Thanks to our brand new and improved library platform, we were able to add more data, more photos, more technical data and more info about how the owners got it done for all you retrofit enthusiasts. Link: buff.ly/9wPwVQG

Thanks to our colleague Andy Cockburn from NAIMA Canada for creating SketchUp drawings for some of our case studies.

Assets like these elevate a case study from a great story to a valuable resource for building professionals.
