The purpose of this 2001 study was to identify causal relationships that have resulted in building envelope problems and successes, in non-combustible high-rise residential buildings in the coastal climate area of BC. This was done by correlating building envelope performance with sources of moisture, and features of design and construction of assemblies and details. This study has facilitated the identification of key factors for successful design and construction of the building envelope assemblies and details.
