    Forced Air Ventilation Systems (PDF 2MB)

    Andrew Pollard, S. McNeil

    This report discusses the methodology and results from monitoring  ten forced air ventilation systems in Christchurch and Wellington. Results showed most homes were already draughty and needed no further ventilation.  Additionally, 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. Forced air ventilation system controllers could be more effective if they are better able to distinguish when favourable times to operate are.

    This presentation, given at Beacon's last research symposium, covers work done to encourage government to ban unflued gas heaters, and retail outlets to stop selling them.  It also reflects the findings of a study of forced air ventilation systems, how well they work and whether they help in creating a healthy indoor environment.

    Backgrounds the issues of healthy and unhealthy home environments and provides evidence that the home environment and health are intrinsically linked. Identifies pollutants that are of concern in new and existing homes. Reviews current knowledge and research base in New Zealand. Found that few comprehensive studies have been conducted in New Zealand and found some large knowledge gaps
