B.1 Moisture and Building Sciences
Starting in the 1980's many aspects of the residential building process began to dramatically change with regards to structure, insulation and tightness in design. With every change the physics of moisture management changed dramatically. We would like to discuss these changes: the cause and the effect on the house as a system, the physics involved with managing moisture in modern homes, and how can we adapt this to today's building process?
