The importance of good indoor air quality

According to the World Health Organization (WHO) “Air pollution from both outdoor and indoor sources represents the single largest environmental risk to health globally”, and causes 7 million deaths a year, worldwide.

On average, people spend 90% of their lives indoors (and some, such as the elderly, even more). This has caused the level of indoor air pollutants to increase 2-5 times higher than outdoor levels. Indoor air pollution can lead to serious short and long-term health problems. There has also been growing evidence that air pollution impacts mental health and may be a factor in conditions such depression and bipolar disorder. It may also have a detrimental effect on children’s learning ability, patient recovery and workforce productivity. For building owners, poor indoor air quality (and poor indoor environments in general) can hit the bottom line: demands from leaseholders and tenants can result in having to carry out costly remedial works to both the building fabric and M&E systems (from lighting to climate control). This can lead to higher running costs and potentially affect market and rental values.
