Description
Course Overview
This session was originally presented at the 2023 IIBEC Building Enclosure Symposium in Orlando, Florida. This course includes the recording of the session, a summative assessment consisting of 10 multiple-choice questions, and surveys required to claim continuing education credit.
Description
Codes are placing increased focus on the performance of the building enclosure. One increasingly popular concept is the introduction of backstops to limit the approach of compensating a shortfall in the thermal performance of enclosures using efficiencies from other systems. A contrast of the backstops adopted in United States and Canadian jurisdictions will take place The challenge for high-rise buildings using the case study from one of Canada’s tallest Passive House buildings will be outlined during this presentation. Examples from the Building Envelope Thermal Bridging Guide (Morrison Hershfield, Evoke, and Open Technologies 2023) will illustrate the thermal limitations of traditional spandrel design and will conclude with examples of how manufacturers are adapting to meet this challenge.

Stéphane Hoffman, PE, P. Eng., has a master's degree-level education that combines structural engineering, building science, and architecture. Hoffman brings a well-balanced consulting approach to the building envelope, blending scientific analysis with an understanding of aesthetic considerations. He is particularly adept at providing innovative design concepts and construction alternatives that provide value by improving durability and increasing energy efficiency. As a key technical leader at Morrison Hershfield, Stéphane has worked on projects throughout North America. He led the expansion of Morrison Hershfield's building science business across the United States and pioneered its facade engineering practice focusing on the conceptual design of cladding and glazing systems.
Objectives
At the conclusion of this session, participants will be able to:
- Assess the design implications for the design of enclosure backstops in US and Canadian energy codes.
- Discuss the special challenges enclosure backstops pose for high-rise buildings, especially for the spandrel assemblies in unitized glazing systems.
- Review the Building Enclosure Thermal Bridging Guide and the effective performance of spandrel assemblies commonly used in current unitized glazing system design.
- Explore recent developments to improve the thermal performance of spandrel assemblies.
- Interpret how the increasing focus on accounting for thermal bridging can be reconciled with the concept of envelope backstops.
Certificate
