Course description

If you are a designer or builder who wants to achieve a high-performing, durable Passive House building, you need to understand control layers. Control layers are materials and systems of materials that are specially designed, selected, and detailed to control water, vapour, and air. They are placed throughout the building, from the roof, walls, and floor to the below-grade enclosure assemblies, details, and interfaces. They consist of membranes and other materials typically described as air barriers, vapour barriers, and water-resistive barriers, or collectively as critical barriers.

The design, selection, and placement of control layers can be challenging. Given the highly insulated nature of passive house buildings, even small mistakes in water and air control can create problems. Simply adding insulation to traditional wall and roof assemblies is risky, so air and vapour control practices must be adjusted to consider the assembly layers and details. Therefore, to design and construct effective passive house buildings, designers and builders must understand the building science behind control layers.

Building Enclosure Control Layers –  Session 3 of 4 Part Series

Session 3 will cover wall air control/air barrier systems and materials

This two-hour session will include 90 minutes of live web-based instruction and demonstrations plus a 30-minute Q&A.

Learning Outcomes

• Understand the challenges with building enclosure assembly design and detailing for passive house projects
• Describe and identify building enclosure control layers
• Design and sketch appropriate building enclosure control layers within passive house building enclosure assemblies and details
• Specify appropriate building materials for different control functions suitable for the higher demands of passive house projects
