David Kayll, Building Science Specialist, and Dave Noel, Building Science Engineer, will be presenting on the recently published Building Envelope Thermal Bridging Guide, which promotes energy-efficiency in buildings by addressing the often ignored issue of thermal bridging in building envelope design. The Guide is quickly becoming a useful reference for local jurisdictions, regulatory bodies, utilities and designers in determining the thermal performance of building envelope assemblies. This presentation will provide an overview of how the Building Envelope Thermal Analysis (BETA) Guide can be used to effectively account for thermal bridging, and develop a more accurate understanding of the overall effective thermal performance of a building design. The effective thermal resistance of enclosure assemblies is essential information in evaluating building envelope thermal performance, for use in energy modeling, and to document performance and compliance for NECB code, ASHRAE 90.1, and LEED or other rating purposes. Insights from project team members relating to current design practice and next steps will also be shared.
