The booklet provides a comprehensive, 65-page overview of modern ducted HVAC cleanliness requirements, explaining why ductwork should be kept clean, and setting out some of the relevant legislative, economic and even moral reasons.
Most importantly, it details the British Standard EN 15780 and Irish Standard EN 15780 'Ventilation for buildings - Ductwork - Cleanliness of ventilation systems' measurement methods and applicable standards for various classes of indoor environment. The Cleanliness Quality Classes are given below:
Low - Rooms with only intermittent occupancy e.g. storage rooms, technical rooms, etc.
Medium - Offices, hotels, restaurants, schools, theatres, residential homes, shopping areas, exhibition buildings, sport buildings, general areas in hospitals
High - General working areas in industries, laboratories, treatment areas in hospitals, high quality offices
There is a helpful flow diagram, amongst many other resources, to help building managers understand the requirements of the standard.
It goes on to describe many of the cutting edge techniques employed by professional duct cleaners to ensure quick, thorough and cost-effective duct cleaning.
George Friend, Chief Operating Officer, of Ventilation Surveys and Services Ltd (VSS), who was recently elected President of the association, said: 'We're pleased to be able to contribute to a better understanding of the issues surrounding indoor air quality, energy efficiency and ductwork cleanliness'.
