In this HCRA-approved workshop, you will learn about construction technology using a building science framework. You will study real life examples and discuss your own experiences and projects in a small group setting. The learning material will be supplemented with various instructional videos customized to the needs of the group.
Learn about the control of heat loss, air leakage, and moisture movement in buildings and learn how to avoid common defects in construction. You will be introduced to construction technology, building science theory and practice. The course will use the Canadian Homebuilder Association Builders’ Manual as a reference.
By the end of the workshop, you will be able to:
- Understand building science and its effects on building durability and occupant comfort
- Understand envelope and mechanical systems
- Discuss approaches to improving indoor air quality
- Explain the “House-as-a-system” concept
Discuss Controlling Heat Loss:
- Describe the heat loss through above and below grade assemblies
- Identify the difference between nominal and effective thermal resistance
- Find the thermal resistance associated with air films, air spaces and common building materials
- Calculate conductive heat loss through building assemblies
- Calculate effective thermal resistance
- Calculate heat loss through windows and predict condensation potential in building assemblies
Discuss Air Leakage and Indoor Air Quality:
- Describe how air moves through an enclosure and the problems it can cause
- Describe air sealing approaches
- Identify materials that can be used as a part of an air barrier system
Discuss Moisture Control:
- Identify and understand first and second planes of protection
- Describe drainage planes
- Provide details for moisture control (vapour, capillarity, bulk water, snow, and ice)
- Use psychrometrics to understand air and water vapour mixtures
