Net Zero Energy Ready Walls – LEEP Videos
Natural Resources Canada (NRCan), through its Local Energy Efficiency Partnerships (LEEP) program, created a package of Net Zero Energy Ready wall design guides. The four wall assembly guides presented in this series offer a variety of construction approaches to achieve energy efficient assemblies as part of a net zero energy project. Each assembly has it’s own unique benefits and drawbacks and therefore must be carefully selected and implemented.
The BCIT Zero Energy Buildings Learning Centre partnered with NRCan and RDH Building Science to fabricate a wall mockup for each guide and produce this video series to provide an overview of the content of the whole package. These videos are a great complement to the original NRCan guides.
Wall Assembly #1 – Split-Wall: Vapour permeable exterior insulation with airtight sheathing membrane
This video is for the NRCan package #1: Net Zero Energy Ready Split Insulated Wall using vapour permeable exterior insulation and an airtight sheathing membrane.
Wall Assembly #2 – Split-Wall: Low permeable exterior insulation as air and water barrier
This video is for the NRCan package #2: Net Zero Energy Ready Split Insulated Wall using low vapour permeable airtight insulation.
Wall Assembly #3 – Split-Wall: Low permeable exterior insulation with airtight sheathing membrane
This video is for the NRCan package #3: Net Zero Energy Ready Split Insulated Wall using low vapour permeable exterior insulation and an airtight sheathing membrane.
Wall Assembly #4 – Double Stud Wall: Interior and exterior air barrier with optional service wall
This video is for the NRCan package #4: Net Zero Energy Ready Interior Insulated Double Stud Wall using an interior and exterior air barrier, with an optional service wall.
Building material and product selection guide
This video introduces Appendix A of the NRCan Net Zero Energy Ready Wall Design package. Appendix A provides guidance on material selection in Net Zero Energy Ready walls.
Selection process for exterior insulation in Split-Walls
This video introduces Appendix B of the NRCan Net Zero Energy Ready Wall Design package. Appendix B presents a process to select insulation materials and determine the vapour control options for split-insulated wood-frame walls.
Getting a copy of the guides
These guides (pdf format) will be published soon and will be available on the NRCan LEEP website.
