Forced air ventilation systems

Andrew Pollard, S McNeill.

This report discusses the methodology used to monitor forced air ventilation systems in 10 houses in Wellington and Christchurch, and the results of the monitoring and operation of forced air ventilation systems.

Time of operation of these forced air ventilation systems was important. At times, operation during the day would increase the moisture levels within the house while night time operation would tend to reduce moisture levels, but also reduce house temperatures.
