This course was initially presented at the 2021 International Convention and Tradeshow. There have been significant developments in methods to quantitatively evaluate building enclosure thermal bridging. While these tools are available to the industry, it is apparent that many project teams do not know how to efficiently incorporate thermal bridging analysis as part of project design. As project teams are incorporating target value design and lean principles through an integrated project delivery, a thermal bridging analysis can bring huge value to the project. An effective analysis quantitatively identifies thermal performance and condensation risk, while working with the project team to determine the most cost-effective approach to meet the project goals. The thermal analysis can be reconciled with the owner’s project requirements, energy modeling, and HVAC design to realize the full value. This presentation will summarize the technical aspects of thermal bridging while using case studies to show how the process is used effectively to achieve maximum value.

Aluminum-framed curtainwall systems have many positive traits, though they have historically been underachievers with respect to thermal performance. Developments in recent years have improved the options and performance available on the market. This presentation will discuss various modifications that may be made to aluminum-framed curtainwall systems to improve their thermal performance. We will discuss enhancement options for both the glazing and framing systems, such as the addition of non-metal pressure plates, gas-filled insulating glass units, warm edge spacers, and other available features. We will discuss how these thermal enhancements may affect the thermal performance of the system and will also touch on related design considerations, such as weatherproofing, durability, expected service life, and other factors. Mary Arntzen, PE, joined Simpson Gumpertz & Heger Inc. (SGH) in 2015 after several years providing field and project engineering services in the construction industry. She has experience in designing, investigating, and rehabilitating building enclosure systems and provides construction-phase services. She is a project manager for various large and complex projects, often working directly with owners, architects, construction managers, and developer clients, as well as subcontractors, manufacturers, and other consultants. She has extensive experience reviewing glass-and-metal curtainwall systems, windows, roofing, plaza waterproofing, cladding, and below-grade waterproofing systems. Derek McCowan, PE, has over 17 years of experience consulting on building enclosure systems on both contemporary and historical structures. He assists clients with design, construction, and performance testing of enclosure systems at new buildings, performs investigative/forensic work at existing buildings, and provides design assistance for rehabilitation projects. He specializes in exterior wall/cladding systems, fenestration/glazing, roofing and plaza waterproofing, and also has experience with foundation waterproofing, historical masonry, and other systems. He has authored various papers and presentations and has experience as a guest lecturer at local universities. He is also an officer on ASTM Committee C24, Building Seals and Sealants. Read More

Recent evolution of building codes across Canada has certainly raised awareness of effective thermal value for building enclosures, and accurately determining this value for various assemblies is becoming a hot topic. Thermal performance requirements in building codes are generally well defined, but the industry is still learning how best to incorporate these requirements into the design process. Ever-changing and increasingly stringent code requirements also mean the goal posts are not set: regular adaptation is required. This presentation will provide clarity on these issues by answering the following questions: WHERE in Canada are there established enclosure thermal performance requirements? WHAT standards and codes have been adopted in different Canadian jurisdictions? WHEN should effective thermal performance be introduced in the design process? WHO is responsible for confirming that the thermal design is code-compliant? HOW is compliance confirmed and documented? This will include discussion surrounding the available methods of determining effective thermal performance (i.e., 1-D calculations, 2-D and 3-D computer modelling, and physical testing) and their comparable levels of accuracy. WHY does all this even matter? ​ Read More

When the Building Envelope Thermal Bridging (BETB) Guide was launched in 2014, the impact of thermal bridges were largely overlooked in North America. Comprehensive thermal calculations factoring in thermal bridging are now a requirement in many new energy codes and standards due to an increased understanding of their impact and drive to net-zero construction. The next progression is to recognize that structural requirements need to be factored into thermal calculations. This evolution requires reliable data that is readily available, so that cost effective solutions can be efficiently examined. This presentation illustrates this progression with a case study where various claddings and back-up walls are examined from a structural, thermal, and cost perspective. Design assist tools with extensive data sets are showcased to illustrate how optimization can happen early-on in design and how these tools can support specifications that encourage cost effective solutions. This presentation draws from a research project that is significantly expanding the BETB database and developing web-based applications that reduce the effort to optimize the building enclosure. This paper is supported by experience on new construction projects where these approaches have been successfully applied.

This presentation will review three building enclosure assemblies that met the building code yet failed in operation. The reasons for the failures will be explained, and live hygrothermal analyses will be run to show the causes of the failures. One of the projects in design development had an exterior wall assembly that met the building code yet was destined to fail. A live hygrothermal analysis will be run to show why the failure would have occurred. Changes were made to the exterior wall design so that it would not fail. These will be reviewed and a live hygrothermal analysis will be run to prove that it will not fail.

The design, installation, repair, or retrofitting of a metal roof is a complex process that requires skill and patience. The first segment of this presentation will provide learners with a better understanding of the different types of metal roofing, testing practices, and site conditions that are not always a one-size-fits-all when determining the manufacturing process of the metal roof. In his second and third presentations, our speaker will share his wealth of knowledge regarding metal roofing and provide the learners with invaluable tips and tricks relating to design installation, repair, or retrofitting metal roofs.   Read More
