Control of air and moisture movement through the building enclosure can enhance indoor air quality while improving the performance and durability of the building enclosure. Results of indoor air quality research will be presented to demonstrate how airtight building enclosures reduce concentrations of indoor particulates. Because moisture in the building enclosure can also impact indoor air quality, as well as cause premature degradation of the building enclosure
assemblies, the effect of airtightness on moisture in the building enclosure assemblies will be illustrated with case studies and a discussion on an innovative approach to controlling moisture in walls of existing buildings. The session will conclude with a presentation of tools used to evaluate building materials for moisture control.

Learning Objectives:

• Recognize the effectiveness of airtight building enclosures on reducing infiltration of airborne particles.
• Appreciate the need for air and moisture control to protect the durability of building enclosures.
• Apply principles of moisture control to selection of materials for building enclosure.
• Define critical factors in the control of moisture in the building enclosure, including the need for airtightness.
