The importance of indoor air quality in schools and beyond

Gibbons’ HVAC Services manager Andrew Knight has been involved in a very interesting LinkedIn discussion this week, where the issue of indoor air quality (IAQ) in schools was raised.

Studies have shown that poor IAQ in schools and other educational establishments has a direct impact on pupils’ ability to learn. Poorly-maintained heating, ventilation and air-conditioning (HVAC) systems can harbour mould, bacteria and viruses which may be transferred into classrooms and other communal areas via the airstream. Inhalation of such contaminants can cause students to experience headaches and tiredness while lowering their capacity to concentrate.

With many schools located in towns and close to major roads, the concept of ‘fresh air’ from outdoors is not realistic. Therefore, building managers have a responsibility to ensure clean, healthy air is provided for students and staff alike. That’s where Gibbons comes in, with our complete air quality services for occupied spaces, including educational buildings where we have extensive experience.

Gibbons Ultraviolet Solutions

We install state-of-the-art ultraviolet germicidal irradiation (UVGI) systems for air handling units (AHUs) within HVAC equipment. Our offering includes the innovative CoilCare® and InDuct® systems:

CoilCare® applies the disinfecting power of ultraviolet C (UVC) band light to the AHU’s cooling coil, eradicating existing bacteria, mould and viruses and preventing regrowth. 

InDuct® is a specialist automated UVGI system developed for use in ductwork, where it can be remotely controlled. This solution eliminates odours, smoke and chemicals while reducing bacteria, viruses and mould.

These two systems perform both as stand-alone equipment and together as an integrated solution. Installation is quick and hassle free, while our clients enjoy return on investment within 24 months on average.

Gibbons Humidification

Complementing our Ultraviolet Solutions and HVAC departments is Gibbons Humidification, which supplies adiabatic and steam humidification systems, offering precision control, high reliability and low-energy output.

Recent outbreaks of Legionnaire’s disease in New York have meant the safety of indoor air is once again in the news. Along with a completely fail-safe system against Legionella which sees water flow shut down in the event of a malfunction, our systems do not use recycled water. In addition, our humidifiers include a UV steriliser which has a minimum disinfection rate of 99.99 per cent.

We’ve carried out humidifier installations, servicing and maintenance across Europe, serving clients in all sectors. To discuss your humidification requirements, call Steve Rix on 07966 423165 or email
