@article{23331, author = {Iain S Walker and Tom W Forest}, title = {Field Measurements of Ventilation Rates in Attics}, abstract = {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.}, year = {1995}, journal = {Building and Environment}, volume = {30}, number = {3}, pages = {333-347}, language = {eng}, }
