Abstract
In this article, the author addresses exterior wall assemblies by presesting the scientific principles and regional variations of humidity, condensation, and water vapor from multiple sources, and their transmission through roofs, the building envelope, and other building materials. Included will be the typical sources - both intended and unintended - and their impacts on building components, based on recent forensic cases. Good design practices and construction details for dealing with typical sources will also be featured. This topic will be discussed in terms of varying heating and cooling climates in North America.
