Course Description

This course provides students with a holistic perspective of the overall satisfactory performance of the building envelope as far as airtightness is concerned.

Supported by 30 mobile building envelope assemblies, the course will showcase various methods of improving air tightness of wood, concrete, and steel-framed buildings. Furthermore, it demonstrates how the presented methods will have an impact on moisture management, energy efficiency, and thermal comfort. In addition, all presented air barrier methods will be explored and reviewed in relation to long-term durability, adaptability to future repair and renovation.

With the focus on delivering interactive learning, this course will prepare the industry for the adoption of BC Energy Step Code.
