This guide aims to help the B.C. construction sector realize more energy-efficient buildings by looking at current obstacles and showing opportunities to improve building envelope thermal performance. Version 1.2 expands the thermal performance catalogue with additional data for many newly analyzed assemblies and details. This includes more cladding attachment systems, window interfaces, precast concrete interfaces, wood-frame and brick veneer walls, and other thermal mitigation systems. Version 1.3 adds 99 new details and 363 new scenarios that includes generic and proprietary details and assemblies.
Video 1 – Introduction to the Building Envelope Thermal Bridging Guide
This introductory video provides an overview of the U-value calculation methodology, as well as a summary of the information contained within the BETB Guide.
This video establishes how to incorporate U-value calculations and the BETB Guide within the overall building design process.
This video demonstrates how to conduct the U-value calculations and workflow by following an example of a six-storey multi-unit residential building design.
This video highlights the finer points of specific details and assemblies, that may require additional attention for including their impacts in calculations.
