ABSTRACT
The CSA Group has collaborated with the Canada Masonry Design Centre and York University to review current Canadian masonry standards for adaptation to climate change. An extensive and
comprehensive review of current, formative research literature, best practice guides and international standards was conducted. Consultations with masonry industry stakeholders and
academics provided guidance in the development of recommendations to standards committee members in view of the next cycle of updates to standards. Part 1 of this two-part paper discusses various avenues by which climate change is expected to affect the way in which masonry structures are designed and built. In this Part 2 paper, several proposed changes to current Canadian masonry standards are discussed, highlighting their potential impacts on design and construction practices, as well as on the masonry industry. Proposed changes include new methods for assessing requirements for corrosion protection for masonry connectors, and guidance on achieving the energy efficiency targets outlined in the National Energy Code for Buildings. Research needs are also identified in view of providing better guidance to designers on the quantification of expected durability and service life of masonry materials and related elements.
