10 Important Features of a Wind-Resilient Building

As the effects of climate change bring more extreme and intense weather events to Canada with greater frequency, the resilience of our built environment is tested, with questions raised by some as to whether wood frame buildings can stand up to high winds and tornadoes. The answer is yes, they can. This session will examine the anatomy of a wind-resilient building. Concepts from the recently published standard, CSA S520 “Design and construction of low-rise residential and small buildings to resist high wind” will be illustrated. This Standard contains best practice guidance for the design and construction of low-rise, wood-frame buildings to withstand high winds corresponding to EF-2 tornado-level wind speeds. The guidance in this Standard is based on, and written to, supplement the requirements specified in Part 9 of the National Building Code of Canada.

Learning Objectives:

  1. Participants will be introduced to the new, recently published standard, CSA S520 “Design and construction of low-rise residential and small buildings to resist high wind”.
  2. Participants will understand that additional lateral and uplift resistance considerations are necessary to ensure homes across Canada can withstand the effects of climate change.
  3. Participants will be shown prescriptive details and solutions to ensure Canada’s housing and other small buildings will be more resilient to the effects of a high wind event such as an EF-2 level tornado.
  4. Participants will review what the new standard covers and why it is a valuable tool. The standard provides:
    • Prescriptive wind design loads or guidance for developing loads so that designers can quickly complete designers which may not be directly covered by the standard.
    • Prescriptive fastening details for roof sheathing, wall sheathing, gable end wall bracing, cantilevered roof overhangs, truss over-framing.
    • Prescriptive design spans for roof joists, roof beams built-up studs on sides of openings.
    • Prescriptive design solutions for ensuring a complete uplift wind resisting load path from the roof down to the foundation.
    • Prescriptive guidance for roof covering, garage doors, fenestrations and cladding.
