This course has been replaced by XZEB 1120 Airtightness and Low-TEDI Enclosures of Zero Energy/Emissions and Passive House Buildings. This course will develop knowledge of building airtightness to meet the requirements of the Upper Steps of the BC Energy Step Code including the Passive House standard. The course starts with a lecture to refresh understanding of air flow fundamentals as they relate to building enclosure assemblies and the BC Energy Step Code. In a full day students will apply this knowledge by constructing and evaluating various air barrier strategies based on sample projects. The strategies and details constructed aim to facilitate a critical comparison of the performance, constructability, and costs of different approaches to meet the airtightness (ACH) metrics of the BC Energy Step Code or the Passive House standard. Students will compare materials (membranes, insulation, tapes, fasteners, etc.) and their application in an air barrier system. Learning will cover various air barrier details (above and below grade walls, roofs, etc) and detailing solutions for interfaces, windows, and penetrations. Students will also observe a blower door test and practice locating and repairing leaks on interior and exterior air barrier systems.
- No prerequisites are required for this course.
- This course isn't currently offered through BCIT Part-time Studies. Please check back next term or subscribe to receive email updates.
Upon successful completion of this course, the student will be able to:
- Demonstrate an introductory understanding of air flow fundamentals as they relate to building enclosure assemblies.
- Be aware of the importance of planning and coordination from design through to construction and testing to meet the Part 9 requirements of the BC Energy Step Code.
- Explain selection considerations for on air barrier material and accessory durability and performance.
- Compare material properties (membranes, tapes, components, etc.) in the application as an air barrier system.
- Practice installation of various air barrier solutions to achieve the airtightness (ACH) metrics of the BC Energy Step Code and the Passive House standard.
- Compare the performance, constructability, and costs of several different air barrier approaches to meet the airtightness (ACH) metrics.
