Just wrapped another case study: a century-old Toronto semi-detached home sheds its gas dependence and drafts. Through a #deepretrofit, the home slashed its energy demand by over 70%.

Another case study, pipin’ hot, straight outta the high-efficiency range (powered by renewables, of course). The #deepretrofit cut this 100-year-old brick home’s energy needs by 70% with a tried-and-true combo of envelope upgrades, mechanical electrification and a dollop of solar.

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.

This phased #deepretrofit in Ontario started back in 2022. Now they've just passed the midway point - foundation, mechanical and attic are done, and the home is already using 60 per cent less energy. Check out the case study here and follow us for updates.

@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.

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.

There’s always a story behind every retrofit in our library, but our latest case study out of Quebec is particularly awesome. In 1965, a barn was converted to a home. Sixty years later, a #deepretrofit transformed it into a high-performance home.

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.
