About this course

Spend an hour learning about building assemblies with Peter Yost of BuildingGreen.

Heat dries them out, so the more we manage energy flows through our building assemblies, the more we need to manage moisture on, in, and through those same assemblies.

This lecture covers just how heat and moisture can move in building assemblies, how to manage both, and the tools that are available to evaluate or predict hygrothermal performance of building assemblies.

Great course. We have to be conscious of how our building assemblies are dealing with moisture as well as heat so that we don't end up with the unintended consequences of moisture buildup.
