CIBSE, KS17 and indoor air quality

The Chartered Institution of Building Services Engineers (CIBSE) is a professional body that sets standards and provides best practice advice for building services engineering. CIBSE’s guidance and codes are internationally recognised, including its Indoor Air Quality and Ventilation (KS17) publication.

KS17 examines indoor air quality (IAQ) and the effect it can have on the health and performance of building occupants. The essential document includes information on “common pollutants, pollutant sources and related health issues” along with advice on “achieving optimum IAQ” and “reducing the risk of poor IAQ”.

Airborne pollutants include particles of dust and dirt, along with chemical-based fragrances and cleaning products. KS17 lists the effects of these contaminants, including lung irritation, bronchial asthma, allergic rhinitis and aggravation of eczema symptoms.

The consequences of workplace building occupants being exposed to poor-quality indoor air and developing these conditions – apart from ill health – include reduced productivity, increased absenteeism and a rise in staff turnover rates. 

Employers and building managers looking to comply with CIBSE guidelines and protect their employees can turn to innovative ultraviolet germicidal irradiation (UVGI) systems such as those provided by Gibbons Ultraviolet Solutions.

Gibbons has developed a range of solutions that use powerful ultraviolet-C (UVC) light to eradicate pollutants from the air and on surfaces within occupied spaces including offices, hotels and healthcare facilities.

Included in the Gibbons range is CoilCare®, a low-maintenance system consisting of UVC photoniser lamps mounted within the air handling unit (AHU) of a building’s HVAC system. CoilCare® destroys pollutants such as mould, germs and bacteria on the cooling coil surface and in the surrounding air, with continued use preventing re-accumulation. As well as preventing pollutants from entering occupied spaces, the system returns AHU performance to as-new, improving energy efficiency and equipment lifespan.

CoilCare® is a chemical-free solution that gives building managers peace of mind that building occupants are breathing clean, healthy air, while quick return on investment via energy savings makes it an affordable solution.
