%X Field tests were carried out in two flat ceiling, residential attics at a dedicated test site over a two year  period. The scope of this paper is to present measurements of ventilation rates, indoor-attic exchange rates,  temperatures and wood moisture contents at various locations in the attics. Attic ventilation rates are  correlated with wind speed, wind direction, and attic-outdoor temperature difference. Wind speed is shown  to be the dominant driving force for ventilation; however, wind direction is important particularly when the  attic is sheltered.
