« Poorly Ventilated Buildings Affect Air Quality and can Contribute to the Spread of Disease »

The following article published by the WHO (World Health Organisation) highlights the relationship between ventilation and airborne disease.

« Poorly ventilated buildings affect air quality and can contribute to the spread of disease… ». There has been evidence to support the fact that poorly ventilated buildings have higher risks of infectious disease transmission for patients, workers and visitors. The number of air exchanges per hour is an important factor in reducing transmission of infectious diseases. If the number of air exchanges is insufficient the risk becomes greater.

There is no doubt that the findings of this research from hospital wards and clinics will apply to a range of different environments and scenarios. For instance, public transport or any confined public space.

WHO further state that well-designed natural ventilation systems are more effective than air conditioning systems, with air conditioning systems potentially transmitting disease,especially when poorly maintained. For this reason many organisations are choosing to use natural or hybrid ventilation systems such as (Flettner’s), with the added benefit of their energy efficiency.

These alarming findings from the WHO reiterate the importance of good ventilation, especially during the current crisis.
