Building occupiers including tenants, employees and landlords are becoming increasingly aware of the importance of indoor air quality for role in reducing staff sick days leading to increased profits and therefore reducing tenant churn. UV light for HVAC or Heating, Ventilation and Air Conditioning is a critical part of treating indoor air quality along with many other facets of the building including but not limited to suitable AC filters, an optimised system and a managed maintenance schedule.

What is interesting is that while most people have heard of UV light or UV lamps for treating indoor air quality, it is difficult to find anybody that can apply the product and explain the sorts of treatment on inactivation rates that would apply under a given scenario or plant, even though there is empirical evidence to substantiate HVAC UV light use.

UV lamps have vastly different levels of irradiation which directly effects inactivation rates which are all dependant on the location of the lamps, the chamber size, array pattern and layout of the UV lamps and the velocity, to mention some of the factors that need to be considered. It is a delicate balance because under sizing UV light for AC will mean the unsatisfactory inactivation while oversizing the UV lamps will use excessive power.

In some cases, where HVAC plants have been installed and/or maintained poorly without subsequent optimisation, poor air filtration, lack of fresh air introduction, moisture or other forms of contamination have persisted over a period indoor air quality testing may be required. A follow up plan can be put in place to bring the whole building and heating and air conditioning system in line with best practise.
