LEEP NZE Wall Guides

This is a series of seven (7) documents: Introduction, Wall-Assembly Guide #1, #2, #3, #4, and Appendix A & B. These detailed reference guides explain the design and construction of ‘high-performance’ wall assemblies using light-frame wood construction. Four wall-types are presented, illustrated with 3D images and large-scale construction details. Each LEEP NZE wall-assembly allows a range of R-values suitable for use in tiered code compliance and Net Zero Energy construction. A selection guide for continuous exterior insulation and wall materials is included, along with detailed discussion of risk-management, ‘critical barriers’, insulation ratios, air-tightness, window installation, condensation, long-fasteners, and the variations required by Canadian Climate Zones.
