This lab course allows for hands-on practice constructing various air barrier systems and assembly details for zero energy/emissions and Passive House buildings to meet the requirements of the national and provincial zero energy (BC Energy Step Code) and Passive House standards. Students will apply a foundational understanding of zero energy/emissions building codes and standards, airtightness and low-TEDI enclosures and work through several hands-on lab stations to build, test, or evaluate various assemblies using a range of approaches and materials. Lab activities will cover air and thermal barrier approaches and details for foundations, above and below-grade walls, roofs, interfaces, windows, balconies, penetrations, and low-embodied carbon insulation material options. This course is offered in person at BCIT High-Performance Lab with some assignments through the BCIT Learning Hub. Students should prepare for light construction and wear steel-toe footwear for lab sessions. Tools are provided onsite.
