Even as codes evolve and construction practices advance, familiar building failures continue to show up on Alberta job sites like frost in the attic, moisture behind frost walls, sweating windows, and cold rooms. Why do the same problems keep coming back, just in different forms?
This full-day seminar challenges builders, designers, site supervisors, and trades to step beyond the checklist approach to construction. We’ll explore the top 10 recurring building science failures; why they happen, how building systems interact to create them, and what actually works to prevent them.
Through real-world case studies and practical examples, you’ll learn how to shift from isolated fixes to integrated solutions. From rim joists to rain screens, HRVs to headers, every component plays a role in whole-building performance. The goal? Design and build homes that don’t just meet code, but perform better, last longer, and make sense in Alberta’s climate.
Key Topics Include:
- Why the same issues keep returning, even in new builds.
- How individual components affect whole-system performance.
The difference between solving symptoms vs. root causes. - Clear, proven solutions based on principles, not just products.
- Whether you’re working on single-family homes or multifamily projects, this seminar offers practical, systems-based strategies to break the cycle of costly callbacks and build smarter from the start.
