Many North American jurisdictions are moving beyond ASHRAE performance requirements for exterior wall assemblies, shifting instead to a holistic, building energy performance standard (BEPS) approach. A line-item-by-line-item approach no longer yields the best results. Instead, component performance needs to be viewed across multiple facets to build high-performance exterior wall assemblies. This presentation discusses the impacts of thermal bridging on compliance with emerging building energy performance standards (BEPS), as well as ASHRAE.
1. Understand emerging building energy performance standards (BEPS), reviewing their similarities and difference compared to ASHRAE
2. Understand the non-linear effect that highly conductive wall components have on the total effective wall R-value
3. Review typical cladding attachment options, comparing their performance across categories such as price, thermal performance, constructability and installation efficiencies, and fire-resilience
