Is There a Relationship Between Ventilation and Health?

Poor ventilation can be associated with unhealthy buildings. Miller (1992), for example, highlights the association of increasing bacteriological concentration with decreasing ventilation rates, while Billington (1982) has produced an historical review of the role of ventilation in improving health and reducing the spread of illness. Studies reported by Sundell (1994) and others have shown that symptoms of building sickness can occur at all ventilation ranges. However, any link between the rate of ventilation and the occurrence of symptoms becomes very weak at ventilation rates above approximately 10 litres/s for each occupant (l/ s.p). It would be incorrect, therefore, to associate all building health related problems with inadequate ventilation. Health problems in buildings may often have much more to do with the character and source of pollutant present in the space rather than the adequacy of ventilation.
