Join VT Group of Companies (Acacia, VerdaTech and Qualistat) with Qualistat Building Performance Consultants for Part 1 of our two-part Applied Learning webinar series on Water Ingress Testing, beginning October 7. Presented by Steven Cox.

This practical series will explore how water testing can be used as an investigation tool, from understanding applicable standards and code references to identifying common leakage locations and interpreting what testing reveals.

• Online | No Cost
• 12:00 PM - 12:30 PM (Q & A afterwards)

Part 1 – Understanding the Standards | October 7
Learn When is a water test a good choice for a building issue and what different assemblies can be tested for water ingress.

Part 2 – Water Testing in Practice | October 14
This session will focus on specific case studies of previous years, how the water testing was completed and what kind of repairs had been implemented to address the identified issues.

A movie stage needs more than just and — it also needs to stay quiet during production.

For this project, Acacia Engineering designed the system to maintain comfortable conditions while minimizing noise and allowing for rapid smoke clearing when needed.

A unique space with very specific requirements, and a great example of how HVAC design has to adapt to how a building is actually used.

A look back at a blower door test setup and some of the practical details that can make a difference in the field.

From adapting the equipment to an oversized doorway to creating a reliable seal and accounting for wind conditions, proper setup is an important part of getting accurate, repeatable test results. It’s a good reminder that airtightness testing is not just about the final number—the conditions and setup behind the test matter too.

A single component falling slightly short of a prescriptive requirement doesn’t always mean the whole design needs to change.

For this 2,200 ft² Alberta home, the proposed exterior wall assembly was slightly below the Section 9.36 prescriptive requirement. By evaluating the home through the Performance Path, the energy model showed the proposed home at 94 GJ/year compared with 100 GJ/year for the Code reference house — approximately 6% better overall.

Whole-home energy modelling can help builders understand how windows, insulation, HRV performance, heating equipment and other design choices work together, while identifying opportunities to avoid unnecessary construction changes and retain planned assemblies where compliance can still be demonstrated.

Take a look through the case study to see how the Prescriptive and Performance Paths compare.

For more information about Section 9.36 energy modelling, visit VTGroup.ca or call 403.251.0683.

Review limited to one project per builder. Subject to availability.

As we get closer to the final session of our Large Building Blower Door Testing series, we’re revisiting this earlier City of Calgary project with Dawson Wallace.

In this project, Stephen Farrell completed a pre-testing walkthrough for a multi-unit building, reviewing the testing approach, guarded blower door setup, multiple fan systems, temporary sealing requirements, and the coordination needed before testing could begin. It’s a good example of how the preparation stage leads directly into the actual testing process.

That’s exactly where our final webinar picks up. Part 3 – Testing, Results & Solutions will focus on what happens on test day, how results are interpreted, and how testing can help identify leakage and guide practical solutions.

We’ve covered the standards and we’ve covered the preparation—now it’s time to put it all into practice.

Our Large Building Blower Door Testing – Three-Part Applied Learning Webinar Series concludes on September 9 with Part 3 – Testing, Results & Solutions.
In Part 1, we looked at the standards, performance targets and metrics behind airtightness testing, and in Part 2, we focused on how to properly prepare the building and testing setup.

For this final session, I’ll take you through what happens during the actual test, how we set it up, how the results are interpreted, and how techniques such as thermography can help us better understand air leakage and building performance.
If you’ve joined us for the first two sessions, this is where the whole process comes together—and if you haven’t, you’re still welcome to join us for Part 3.
