Happening on January 25th with Andrea Pietila and Kathleen Narbonne of RDH, join SBC for an overview of thermal bridging and a detailed review of the Deep Energy Retrofit (DER) Thermal Bridging Guide developed by RDH.

Thermal bridging is important to consider for all buildings as it can have a significant impact on a building’s thermal enclosure performance. It is an especially important part of energy modelling retrofit projects as modelling typically requires calibration to utility bills or measured end-uses. For buildings considering a deep energy retrofit such as those participating in Enbridge’s Savings by Design program, consideration of thermal bridging is required to determine the enclosure performance upgrades and their relative impact on energy use.

This document, referred to as the Deep Energy Retrofit (DER) Thermal Bridging Guide, is intended to address the complexities of predicting and mitigating thermal bridges in early design stage energy modelling for existing buildings. This Guide is supplementary to SBC’s – Part 3 Buildings Energy Modelling Guide and Deep Energy Retrofit Energy Modelling Guide and should be read in tandem.

Section 1 of this Guide provides an overview of thermal bridging and R-values as they relate to heat flow through buildings.

Section 2 of this Guide provides common thermal bridges and associated psi-values for existing buildings and potential retrofit cases that may be used in energy modelling for a DER analysis including for projects participating in the SBD program. The values presented were evaluated for existing high-rise multi-unit residential buildings of mass construction. This typology and construction type has been identified as the most common typology of future DER projects within the SBD program.

Section 3 of this guide provides steps to incorporating the thermal bridge values from Section 2 into an SBD project, following the Building Envelope Thermal Bridging Guide (BETBG) Chapter 5 – Example Utilization of the Catalogue.

This FREE webinar will provide (1) an overview of best practices to understand heat flow through buildings and minimize thermal bridging and, (2) detailed review of the Deep Energy Retrofit (DER) Thermal Bridging Guide developed by RDH.
