A framework for climate resilient performance standard of commercial roofs

The National Research Council Canada (NRC) is working to integrate climate resiliency into building and infrastructure design, guides, and codes. In this article, the authors present a framework for climate-resilient design of commercial roofs that will become part of the Canadian Standards Association (CSA) A123.26, Performance Requirements for Climate Resilience of Low Slope Membrane Roofing Systems.

The detrimental effects of UV on barriers

Water-resistive barriers (WRBs) play a vital role in the performance of a wall system. Unfortunately, barriers can be undermined even before they clad the walls due to ultraviolet (UV) exposure. Understanding and minimizing the impact of UV on WRB is critical to ensuring the integrity of the wall assembly and building performance for years.

Theory of a self-drying roof

Roof enclosures have the largest litigation potential in the construction industry due to complexities in design, application, and environmental exposure. A self-drying roof enclosure would minimize the litigation potential and provide additional benefits, such as increased roof resiliency, reduced financial burden, and minimal impact on the environment.
