FEATURE HVAC SOMETHING IN THE AIR Indoor air quality (IAQ) is a growing concern, both domestically and in the workplace. Recent research by the Royal College of Physicians, and the Building Engineering Services Association (BESA), has placed the issue firmly on the agenda for consumers, as well as those influencing the commercial and industrial sectors. David Cook of Vent-Axia explains how demand control ventilation can be instrumental in improving the air quality in our buildings. I ndoor air quality is now centre stage. The majority of people would agree that indoor air quality has always been important, but the extent to which it actually impacts our everyday environment has not always been front of mind. It should be now as indoor air quality is hitting the headlines in the press. Reporting earlier this year, the Royal College of Physicians found that around 40,000 people die annually in the UK as a result of air pollution, costing more than £20bn a year. Everyday pollutants – kitchen products, faulty boilers, open fires, fly sprays, air fresheners and second-hand smoke – exacerbate the situation, seriously impacting indoor air quality. And with health problems such as cancer, asthma, stroke and heart disease, diabetes, obesity and dementia all linked to poor air quality, it’s clear this issue must be urgently addressed. Workplace indoor air quality Adding further impetus from a workplace perspective is the recent Building Engineering Services Association (BESA) study warning that 70 per cent of office workers believe poor workplace air quality is having a negative effect on their day-to-day productivity and wellbeing. In addition, a further third are concerned that poor indoor air quality could be having a negative effect on their health. While 60 | November 2016 60-61 HVAC – Vent-Axia.indd 60 10/10/2016 16:52
