Building envelope thermal bridging guide

This guide explores how the building industry in B.C. can meet the challenges of reducing energy use in buildings, in part by effectively accounting for the impact of thermal bridging.

Version 1.1 - April 2016

Many details and assemblies were added to the thermal performance catalogue (Appendix A and B) of BETB Guide Version 1.1. The sections related to the cost benefit analysis and market transformation have been removed so that the new version focuses only on providing thermal performance data and how to utilize this information in everyday practice.

Refer to the original version of the BETB Guide released in 2014 for sections related to energy savings and cost benefit analysis (Part 2) and market transformation (Part 3: Significance, Insights, and Next Steps).  These documents are still relevant to current realities but are not material that need to be referenced in everyday practice and have not been updated since the original version of the BETB Guide.

Version 1.0 - October 2014

Most practitioners will find PART 1 and Appendices A and B to be most useful. PART 1 outlines how to effectively account for thermal bridging. Appendices A and B provide a catalog of common building envelope assemblies and interface details, and their associated thermal performance data.

Researchers and regulators will be interested in PART 2 and PART 3, and Appendices C to E. They contain the cost-benefit analysis, and discussion on significance and further insights, of using this guide to mitigate thermal bridging in buildings.
