This presentation summarizes measured data on air pressures across and inside wood frame wall cavities, also included is information on air pressure equalization across wood lap siding and the relationship between air barriers and vapor retarders for moisture control. Overcoming barriers and increased integration of new findings in building science and new technologies in the codes will be discussed. After using alternative building materials and applications for 14 years in the Northern Rockies, this is an assessment of what works and what doesn't. It's all about what's right and wrong with different materials and applications. The answers may surprise you.

Monitored data will be presented from houses with intermittent ventilation and intelligent timing. Results offer a cold dose of reality about the state of new construction and identify opportunities that remain to be captured.
