Description
2024 BES Session: Adaptation of Low-Slope Roof Assemblies against Projected Climate Severities: Evaluation of a New Standard
Course Overview
This session was originally presented at the 2024 IIBEC/OBEC Building Enclosure Symposium in Toronto, Canada. This course includes the following components:
- recording of the live session
- a summative assessment consisting of 10 questions
- two surveys required to claim continuing education credit
Description
The Ontario Building Code requires low-slope roof assemblies to withstand dynamic wind uplift according to the CSA A123.21 standard. This has had a major impact on the industry, obliging manufacturers to design, test, and determine the performance of complete roof assemblies. However, a recent project demonstrated a worst-case scenario: a series of errors involving a lack of site-specific wind values in the design specification, use of alternative methods of compliance presented by the manufacturer that were questionable, and poor quality of material handling and workmanship by the roofer during construction resulted in failure after strong wind events. As the industry tries to cope with these current requirements, the effects of climate change expose the built environment to more severe environmental stressors than what the code prescribes. Extreme weather events—including high wind speeds, intense rainstorms, heavy snowfalls, extended heat waves, and other stressors—are becoming more frequent and powerful. This session will discuss CSA A123.26, an optional standard that builds on CSA A123.21 in addressing the impacts of projected wind extremes and heavy rainfall. This presentation will also explore an evaluation of the CSA A123.26, which revealed some valuable lessons.
