In this session, you will review the key building science and construction of low-TEDI building enclosures (airtight, thermally efficient assemblies with high performance windows and doors).  The session will focus on comparing solutions to achieve the BC Energy Step Code performance metrics (TEDI and ACH) applying knowledge of assembly durability, fire resilient and low-carbon material selection, building science, and constructability. 

Participants in this session will learn to:

• Explain the fundamentals of low-TEDI (thermally efficient) building enclosures
• Compare the materials (optimal performance, constructability, and lower embodied carbon) and construction approaches for low-TEDI assemblies (roofs, walls, below-grade) and components (windows & doors)
• Explain building science considerations in various low-TEDI assemblies
• Explain how to find or train trades to implement project low-TEDI details (high performance windows, low thermal bridge details, insulation)
