Real-time ventilation and infiltration measurements were made on ten single-family homes. Seven of these had crawlspaces and were in the Pacific Northwest Two had daylight basements and were also in the Pacific Northwest. The other is an energy efficient demonstration "smart" house built in Rocklin, CA, and was built on a crawlspace. All of the homes were tested under heating season conditions. The home in Rocklin was also tested under cooling conditions. Each house was divided into multiple zones, including buffer spaces, and each test period lasted about a week. Tests were conducted to compare ventilation and infiltration during periods when the forced-air distribution system was on to those times when it was off. Special one-time tests were also done with exhaust fans operating. Detailed data was collected in each house using a real-time multi-tracer measurement system. This paper presents the results of testing on these ten buildings. Blower door test results are compared, and the ability of various models to predict infiltration for the different foundation types are analyzed.
