EN 15780, a European standard which is generally translated into national standards of European countries, and VDI 6022, a German standard, are both standards that relate to the ventilation of buildings, specifically with regards to the hygiene of the ventilation systems.

EN 15780

EN 15780 is a European standard titled "Ventilation for Buildings - Ductwork - Cleanliness of Ventilation Systems." Published in 2011, it provides guidelines and requirements for the cleanliness and hygienic aspects (inorganic contamination and microbiological contamination) of ventilation systems in buildings. The standard applies to both residential and non-residential buildings and it covers topics such as the cleanliness of ductwork, filters, and air handling units (AHUs). It outlines methods for assessing the cleanliness of the systems and provides guidance on cleaning procedures to maintain proper air quality and prevent the growth and spread of contaminants.

VDI 6022

VDI 6022, first published in 2006, is a German standard issued by the Association of German Engineers (VDI) titled "Hygiene Requirements for Ventilation and Air-Conditioning Systems and Devices." It focuses on the hygiene aspects of ventilation and air-conditioning systems. VDI 6022 provides guidelines for planning, installation, operation, and maintenance of these systems to ensure indoor air quality and prevent health risks. The standard covers various topics, including air quality, system design, material requirements, maintenance, and cleaning procedures. VDI 6022 is specifically intended for non-residential buildings, such as hospitals, laboratories, and offices. The standard covers similar aspects of the ventilation system as EN 15780, including air intakes, ductwork, and filters.

Differences

One key difference between the two standards is the level of detail they provide. EN 15780 is a more detailed standard, with specific requirements and recommendations for different aspects of the ventilation system. VDI 6022, on the other hand, is a more general standard, providing guidelines that are intended to be adapted to specific situations.

Another difference between the two standards is the approach they take to risk assessment. EN 15780 requires a risk assessment to be carried out for each ventilation system, taking into account factors such as the building occupancy, the type of ventilation system, and the intended use of the building. VDI 6022 also requires a risk assessment, but the emphasis is on the identification of potential sources of contamination and the selection of appropriate control measures.

In summary, EN 15780 and VDI 6022 are both standards that provide guidelines for the hygiene of ventilation systems in buildings. EN 15780 is a more detailed standard that applies to both residential and non-residential buildings, while VDI 6022 is a more general standard that applies specifically to non-residential buildings. EN 15780 requires a risk assessment to be carried out for each ventilation system, while VDI 6022 places more emphasis on the identification of potential sources of contamination and the selection of appropriate control measures.
