OBC Division B, Part 5 requires that “…assemblies exposed to the exterior shall be in accordance with good practice such as described in CSA S478, “Guideline on Durability in Buildings”.
This means architects are responsible for understanding and applying durability concepts to environmental separations (building envelopes or building enclosures) and their structure. Failure to do so can lead to catastrophic losses and massive claims against architects. The “Leaky Condo” crisis in British Columbia in the late 1990s is an example of the widespread economic and social consequences where adherence to the fundamental concept that buildings are required to be durable was ignored by the design professions and construction industry.
The CaGBC offers a LEED credit for “Durability” based on a documented process in accordance with the CSA S478 Guideline, and the Toronto Green Roof Bylaw references the Guideline.
There must be something in this document that can be used by architects to support code compliance and good practice. This program is directed towards understanding what that is.
This program will review the content of CSA S478, Guideline on Durability in Buildings, consider some of the implications impacting architects’ designs and discuss opportunities for architects to reconsider their approach to building envelopes to improve their overall durability.
This program for the OAA is a collaboration between Pro-Demnity Insurance Company and Morrison Hershfield Limited with the objective of enhancing the design services provided by Ontario architects and reducing claims against architects where building envelopes are considered not durable
