CESA 1111 - Zero Energy Building Enclosures: Airtightness Lab (for Residential Buildings)

Centre for Energy Systems Applications Part-time Studies Course

School of Construction and the Environment

BCIT is planning for a substantial return to on-campus activity for the fall 2021 term as informed by BC Public Health Officer guidelines. Refer to each course listing for details.

Course Details

This lab course will allow students to practice installation of various air barrier system approaches to meet the airtightness requirements of the Upper Steps of the BC Energy Step Code (1.0 ACH) and the Passive House standard (0.6 ACH). Students have already developed foundational understanding of air barriers through pre-requisite courses. With eight hours in the BCIT High Performance Lab, students will work through a number of hands-on lab stations to build, test, or evaluate air barrier systems using a different approaches and materials. Lab activities will cover various air barrier details for foundations, above and below grade walls, roofs, interfaces, windows, balconies, penetrations, and more. Students will develop quality control methods and practice locating and repairing leaks in air barrier systems. Builders, tradespeople, insulators, designers, building officials, and energy advisors would benefit from this course.


Prior learning on airtightness and air barriers systems is required. Students must be registered for or have already completed any one of the following: CESA 1110, CESA 1150, CESA 1155, CESA 1160, CESA 1500, CESA 1501, CESA 1505.
