Three Failures and a Save: Case studies of building enclosure failures at three buildings, plus successful application of lessons learned and hygrothermal analysis on a fourth building.

Presenter, Len Anastasi, will review building enclosure assemblies that have experienced failures as well as a building enclosure assembly designs that would have resulted in failures and the changes to the design that avoided the failures. Basic building science and physics will be reviewed. Live hygrothermal analyses will be run to show which building enclosure assemblies work in their respective climate zones and which do not.
