Pacific Northwest Residential Ventilation Effectiveness Study
This report provides data and conclusions about the actual performance of different types of ventilation systems as installed and operated in relatively airtight homes. Overall, this study found that total ventilation is not a determining factor in ventilation effectiveness. A key factor is the ventilation delivered to each occupied space. This is coupled with a…
