Market-Ready High-Performance Walls: Phase 1 Report

The construction of high performance or “advanced” walls represents a significant energy efficiency opportunity for the regional new home construction sector. This report documents the detailed process, components, and estimated costs of three highly energy efficient wall system archetypes:

1. Thermal Break Shear Wall (TBS);
2. 2×6 Intermediate frame with exterior rigid insulation;
3. 2×4 double stud with blown-in fibrous insulation

This is the first of two reports that NEEA commissioned Earth Advantage Inc. to produce. This first report defines the walls and market barriers. The second report provides information needed to address the barriers and provides code officials and training organizations with information they need to more actively support use of these wall types.
