ONLINE: Controlling Water and Vapour – From Rainscreens to Vapour Barriers – 26 Oct 2023
Date: Thursday October 26, 2023 from 10am – 12pm PT
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 2 of 4 Part Series
Session 2 will take a deeper dive into rainwater control and detailing as well covering vapour control for walls.
This two-hour session will include 90 minutes of live web-based instruction and demonstrations plus a 30-minute Q&A.
- 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
- Passive House Designers and Consultants
- Builders, architects, architectural technologist and engineers
- Building officials and planners
- Anyone interested in the subject
Prerequisites / required background knowledge
No prerequisites are necessary, but a basic understanding of passive house principles, including Passive House Canada 120A, would be beneficial.
