CSA S505:20 PDF Download

CSA S505:20 is a standard developed by CSA Group to address the risks posed by high winds and snow drifting on northern infrastructure in Canada. The standard focuses on various aspects, including weather data, climate variables, projections, and forecasts, as well as strategies for reducing damage and adapting to climate change. It also provides guidance on improving function and accessibility and utilizing design and construction techniques.

The scope of the standard is to provide guidance to designers, builders, operators, and owners of northern infrastructure in addressing the increased risk of damage caused by higher and more frequent wind loads and associated snow drifting. It emphasizes the importance of considering climate change and its potential impacts on infrastructure.

However, it is important to note that the standard does not cover uniform snow loads on existing roofs (which is addressed in CAN/CSA-S502), the decommissioning of buildings subjected to snow or wind overload, or the detailed design of infrastructure. These topics fall outside the scope of CSA S505:20.
