Roofs are subject to very extreme physical and environmental conditions. They are, for the most part, the first line of defense against exterior elements, and, in many instances, the most neglected building element. Roof maintenance does not have to be a very complicated and time-consuming endeavour.
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.
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.
High-density polyiso cover boards offer compressive strength that protects the low-slope commercial roof system from traffic, puncture, hail damage, and other impacts of weather. These easy-to-install, lightweight boards can also increase the roof system’s durability.
Japanese architect Junya Ishigami, celebrated for his experimental structures that interpret traditional architectural conventions and reflect natural phenomena, has designed the 2019 Serpentine Pavilion in London, United Kingdom.
The Al Janoub Stadium in Al Wakrah, Qatar, designed by Zaha Hadid Architects with engineering firm Aecom, incorporates cultural references to the city in an abstract manner and combines them with practical responses to the climate, context, and the functional requirements of a football stadium.
