Engineering analysis is a necessary tool to provide fire protection and safety for our buildings. The exponential number of wall assembly combinations and detailing of enclosure assemblies in the built environment prevent the opportunity to confirm fire performance through direct testing. This is especially true with the required investment of time, effort, and cost for larger-scale tests such as NFPA 285. Qualified fire engineering teams, in partnership with third-party labs and product manufacturers, offer the opportunity to extend successful test results beyond the tested specimen through an engineering analysis report. This presentation discusses the opportunities, challenges, and limitations present when considering the acceptance of test data extended to support substitution or modification to an assembly....

Understanding the performance of building materials in real-world conditions is key to a successful building design. Recent studies have shown that the commonly reported R-values of polyisocyanurate foams at room temperature may overstate their real-world performance in cooler temperatures. This decline in R-value is driven by complex phase change mechanisms, which modify the foam's insulation performance. Insulations not performing to the expected levels may result in gaps in designed building enclosure assembly performance and quality. In this course, through a theoretical framework and empirical data, it is shown that optimized polyisocyanurate foam insulation results in better insulation performance leading to improved energy savings and reduced potential for condensation. Participants are encouraged to explore innovative insulation materials, understand differences between them, and match optimal materials to specific applications, while meeting modern construction codes and regulations. By matching the right insulation materials to the application, architects can contribute to energy-efficient and cost-conscious construction practices, and help buildings reduce their impact on the environment...

The 2024 International Energy Conservation Code (IECC) fundamentally shifts how the thermal performance of building enclosures is designed and evaluated. In the 2024 IECC Chapter 4 Commercial Energy Efficiency, compliance now requires design teams to account for linear and point thermal bridging, as does ASHRAE 90.1-2022, which is incorporated by reference. This impact will notably change how design professionals consider typical building details like parapets, cladding attachments through continuous insulation, window perimeters, and more. Through a side-by-side review of previous and current requirements, this course will bolster design professionals’ understanding of the steps needed to address thermal bridges and how to incorporate these results in prescriptive path, performance path, and COMcheck compliance calculations. By examining the updated air leakage testing requirements codified in the 2024 IECC, professionals will learn to decipher whether whole-building air leakage is mandatory or if the air barrier design and verification approach will apply to their project. This course will explore the practical impacts of the new energy code requirements, reveal strategies for meeting compliance, and share tools that can help design professionals stay ahead in a rapidly changing energy code landscape.
