The Association of Ductwork Control Contractors and Allied Services (ADCAS) is urging facilities and building managers to focus on ductwork as central to the importance of Indoor Air Quality (IAQ).

Ductwork is a vital element of a building management system which influences energy efficiency and IAQ. The latter has a very significant impact on occupants’ health. Poor IAQ has been linked to Sick Building Syndrome, reduced productivity in offices and impaired learning in schools.

Pollutant sources which cause low indoor air quality are both internal and external. For example, emissions from carpets and photocopiers or contaminants from traffic and industry can all impact on occupants. Ductwork and ventilation are extremely important for ensuring a good flow of fresh air. This means that keeping ductwork clean and in good repair is very important.

ADCAS President Malcolm Moss says: “Cleaning ductwork is something that needs to be scheduled regularly, and which needs to be carried out by professionals. It’s not simply about indoor air quality, but also about the safety of the building too. Poorly maintained ductwork can be a source of problems when it comes to fire safety.”

ADCAS recently published a Guide to Ductwork Cleaning & Access.  This free guide is available from the ADCAS website (www.adcas.couk) and it highlights rules that building managers should be aware of, including the BS EN 15780:2011 British and European Standard which specifies the assessment criteria for the cleanliness and cleaning procedures for both new and existing ductwork.

What’s more, the ADCAS Guide not only provides guidance to building owners, contractors and building managers on the correct cleaning procedures, but it will also help them to adhere to legislation which covers fire safety and installation standards.

Malcom Moss adds: “Ductwork is a technology that requires consistent monitoring and cleaning to ensure a pleasant and safe indoor environment. Setting out a regular and rigorous cleaning and maintenance schedule for ductwork will not only increase the productivity of occupants, but will also save money in the long-term by helping to prevent absence through sickness.”
