So perhaps the horrendous and rampant transmission of the Covid-19 virus could be the reality check that gets us all thinking about air quality and the effect that so many contaminants, not just viruses, have on our health and wellbeing. The benefits of good indoor air quality have
been well documented for many years, whether that is benefits to our children’s education and learning, or to the productivity and increased profitability of a company’s employees, the

importance of maintaining a good indoor climate is something that should have been on our radar long before Covid-19 forced us to consider it. Whilst there are many differing opinions and still much unknown about the transmission of this particular virus and the best methods of preventing it, there are a number of areas where there seems to be a consensus of opinion and agreement, not just in relation to virus transmission, but to optimum indoor climate generally. It now seems to be accepted without question that some of the best protection we can use is to ventilate. Historic focus on indoor climate

has largely emphasised temperature control, which is of course important in terms of comfort, but ventilation is paramount in respect to our health and wellbeing – the higher the rate of ventilation, to give maximum dilution of contaminants, the better.
This may suggest that ‘all-air’ systems are
answer, but these will often be impractical or uneconomical in terms of the plant and services size necessary to deliver sufficient levels of cooling to the building. In such cases where secondary cooling systems will be required, there are choices; those that rely on a primary air supply to function would by default always ensure
