About our On the Ground / Off the Record Events

Let's learn together. Join us for PBC's On the Ground / Off the Record (OTR).


Our Mission: strengthen the passive house movement through honest conversation. Through OTR we share mistakes, lessons learned, concerns, warnings, and other teachable moments. These talks are never recorded or available for viewing after the live event.

These online 45-minute sessions will feature one presenter sharing a single topic for 15-minutes, followed by a 30-minute discussion based Q&A.


OTR sessions are free for PBC members. Non-member fees = $10 per session. Members - contact tech support here for your free ticket code.

Boots On The Ground

Boots On The Ground (BOG) is a dynamic conference series that brings together leaders from the design and construction fields to share ideas, network, and learn about products, and new solutions to get the job done. Boots on the Ground was founded by the BlueGreen Group in 2013 who passed the torch to Passive Buildings Canada in 2018. Each event features a mini-trade show made up exclusively of sponsors, food and drink, and one hour of networking time before and after the presentations. The presentations feature three talks, each presentation a maximum of 20 minutes with no Q&A (we encourage questions during networking). We aim to have one speaker be a builder and one a designer.

While Boots On the Ground events are typically invite only, you can find our backlog of recorded presentations on our YouTube channel!


We hope to have BOG in-person events return later in 2021, pending the status of the COVID-19 pandemic.
