Module 5: Air Barriers for the BC Energy Step Code

BC Housing pre-approved 3 hours online training course, 3 cpd
We will discuss how to appreciate the importance of the building air barrier as a way of significantly improving energy efficiency with minimal construction cost implications.
We will discuss how airtightness impacts energy performance from code minimum to current practices to best practices.
We will discuss how to describe the four attributes of a correctly installed building air barrier: air impermeability, durability, continuity, and stiffness.
We will discuss how to compare the design and construction sequence considerations of typical interior and exterior air barrier systems, including key details for implementing them successfully.
We will discuss how to assess cost trade-offs of different air barrier approaches including materials, installation techniques, sequencing, and effectiveness
So ultimately, builders would be able to select an appropriate air barrier approach for a given roof, wall, floor, and party-wall assembly based on performance, cost-effectiveness, and constructability, bearing in mind current and future BCESC requirements.
We will discuss a list of the key factors that contribute to the successful installation of a complete air barrier system.
We will discuss how to manage the key wood-frame construction practices that can interfere with achieving a successful air barrier, including coordination and education for all trades interacting with the enclosure.
We will discuss how to coordinate qualitative and quantitative testing at the appropriate times and use the results to track quality control of the air barrier.
So ultimately, builders would be able to apply knowledge of the correct design and installation practices for a given air barrier approach to properly manage the planning, installation, and testing of the building’s complete air barrier.
Upon completion of this module, builders would have a better understanding of the different options when selecting an air barrier approach, and the important planning steps associated with a successful air barrier.

This course is not equivalent to the eight training modules that were developed by BC Housing to prepare builders to build to Step 3 of the BC Energy Step Code. Completion of this courses will not satisfy the step code condition placed on general contractor licenses by BC Housing.
