In this backyard membrane test, three weather resistive barriers are exposed to the same situation to see how they deal with vapor diffusion. The thermometer...

This channel hosts video material in support of the BC Energy Step Code. The BC Energy Step Code is a new opt-in provincial standard that aims to create healthier, more efficient, and more comfortable new buildings. It does so by establishing measurable energy-efficiency requirements for new construction.

Minimizing thermal bridging through the building envelope is a key design aspect for achieving net-zero energy-ready (NZER) buildings. However, this can seem quite complicated for project teams, especially when much of the envelope is unknown during the early building design stage. Finding the optimal envelope solution for thermal performance that also incorporates architectural intent, cost savings, constructibility and durability is only achieved when the entire project team is engaged to collectively meet these goals. This playbook outlines good design practices for anticipating and dealing with thermal bridging in order to meet the expectations of the BC Energy [Step Code], Passive House or other NZER standards. The intent of this document is to provide guidance for design teams including developers, architects and consultants, to effectively tackle thermal bridging while meeting all project goals, not just thermal performance. 0:00 - Introduction 2:44 - Why does thermal bridging matter? 5:17 - How to set and achieve thermal bridging mitigation targets 9:06 - An example of thermal bridging mitigation for a multi-unit residential building 10:40 - Five tips to avoid thermal bridging pitfalls To access the playbook, check out 'Thermal Bridging In Net-Zero Energy-Ready Building Design' on the ZEBx.org website 'Resources' - or follow the link here: https://www.zebx.org/playbook-dealing-with-thermal-bridging-in-net-zero-energy-ready-building-design/
