LEEP: Net-Zero Energy (NZE) Wall Guide Training

Author/Contributor: ENBIX, NRCAN’s LEEP, BILD Lethbridge

Alberta Context: These videos were recorded from NRCAN’s LEEP Net-Zero Energy (NZE) Wall guide session from March 2025 in Lethbridge. All content is relevant to Alberta.

Summary: 

The LEEP net zero energy wall guides provide seven documents designed to improve wall assembly performance for net zero energy buildings. These resources are targeted at builders, designers, architects, and building officials.

The guides aim to enhance wall performance by:

• Increasing effective R-value and reducing thermal bridging.
• Improving air tightness to minimize energy loss.
• Enhancing resiliency through moisture and vapour management.
