ast month I mentioned poor water quality and the dangers it can pose to both human health, as well as heating plant reliability and efficiency. We focus more on it in this issue with features that cover the reduction of scale build up in a school’s water supply (p28) and UV treatment of swimming pool water (p31), both of which are intended to improve hygiene and eliminate any health risks. This month I’ve turned my attention to air quality with a visit to Waterloo Air Products’ factory and test lab. It provided a fascinating insight into the difference that a seemingly simple device, such as a grille or diffuser, can make to the airflow of an internal space and therefore the affect it can have on the occupants.


All we need is the air that we breathe L


This is a very topical subject at the moment with air quality, or rather the dangers of pollutants in the air we breathe, hitting the headlines for all the wrong reasons. Recent studies have shown that prolonged exposure to common pollutants poses a serious threat to public health. The investigations by King’s College London over the last five years have found that poor air quality can affect not just the lungs, but also many other organs in the body, including the brain. Of course there are many factors that can affect air quality, with emissions from traffic, industry and aircraft the most obvious contributors to environmental toxicity over which we have very little influence. The air inside buildings, however, whether it’s the workplace or home, can be

controlled, and as that’s where we spend the majority of our time, ensuring it’s optimised is vital to the health of all the occupants. A recent YouGov survey commissioned by the Building Engineering Services Association (BESA) reported that almost 70 per cent of office workers believed poor air quality in their place of work was having a negative effect on their day-to-day productivity and wellbeing. Factors affecting indoor air quality can include room temperature, light and noise, humidity, CO2, chemical


contaminants (volatile organic compounds – VOCs) and naturally occurring poisons. Air quality improvements can be made through the deployment of advanced HEPA and carbon- activated air purifiers to screen out harmful pollutants, but improving ventilation and paying attention to airflow in a new or refurbished building are just as important.
