DIN EN 16798-3: Standard for HVAC in non-residential buildings
Energy efficiency in non-residential buildings such as offices, factories or schools is not just vital in terms of saving money on energy bills, it’s also a crucial consideration for environmental protection and sustainability. In this regard, the DIN EN 16798-3 standard, introduced in 2017, plays a central role by setting clear performance requirements for heating, ventilation and air conditioning systems (HVAC), as well as room cooling systems within non-residential buildings.
Closely aligned with the specifications of the World Health Organization (WHO), this standard mandates adherence to specific air pollutant limits. Effective filtration should protect both people and the environment by continuously improving ambient air quality, even when air pollution levels are low. Studies show that even minor improvements in indoor air quality can have a significantly positive impact on people's health and well-being. This research underscores the great importance of having fully DIN-compliant ventilation systems in non-residential buildings.
DIN EN 13779 becomes DIN EN 16798-3
The previous standard, DIN EN 13779, was replaced in 2017 by DIN EN 16798-3:2017-11. This new standard is part of a series that addresses the clear energy assessment of buildings. Specifically focused on non-residential buildings, it encourages systems that regulate air quality and temperature. The main objectives are to simultaneously promote energy efficiency and reduce energy consumption by using optimised ventilation concepts, which are crucial both economically and ecologically.
By also adhering to the DIN EN 16890 standard, which helps determine the most suitable air filters for specific applications, operators can obtain a better overview and greater control over the most efficient and effective air filtration measures that can be used within their buildings.
The core requirements of the DIN EN 16798-3 standard
DIN EN 16798-3 sets specific performance parameters for air conditioning or HVAC systems within non-residential buildings. These parameters focus not only on the efficiency of the devices but also on their ability to improve indoor air quality without unnecessary energy consumption. According to the standard, ventilation systems must efficiently regulate air exchange in non-residential buildings, thereby ensuring minimal energy losses.
It is essential that room cooling and ventilation systems are precisely matched to the building's size and usage. Oversizing or undersizing can lead to significant energy inefficiencies. The standard specifies how these systems should be planned and operated in order to achieve optimal energy efficiency. Additionally, it also emphasises the importance of regular maintenance and inspection to help guarantee long-term high performance standards.
Outdoor air quality and filter use: Specifications of DIN EN 16798 part 3
Based on pollution levels, the DIN EN 16798-3 standard outlines classifications for both outdoor and indoor air quality, dictating the type of air filters needed for clean air in non-residential buildings.
There are three classifications for outdoor air quality:
- ODA 1: Complies with WHO guidelines and all national standards or regulations on outdoor air quality. The air is only briefly contaminated with dust, such as pollen, and is free of harmful gases.
- ODA 2: Exceeds WHO guidelines and national standards by up to 1.5 times. This may include air with a high concentration of particulate matter and/or gaseous pollutants.
- ODA 3: Exceeds all directives, standards or regulations by more than 1.5 times, and may include air with extremely high concentrations of gaseous pollutants and particulate matter.
.
According to DIN EN 16798-3, there are five classifications for indoor air quality (supply air quality – SUP). These SUP standards apply if the supply air complies with the WHO limit values and all national standards or regulations on air quality, taking various factors into account:
- SUP 1 Factor 0.25
- SUP 2 Factor 0.5
- SUP 3 Factor 0.75
- SUP 4 Factor 1 (direct compliance)
- SUP 5 Factor 1.5
The prevailing air pollution levels determine which filters should be used for smooth, safe, and energy-efficient filtration.
The recommended filter classes are based on EN 779, which was replaced by DIN EN 16890 in 2017. As DIN EN 16890 uses new approaches and mechanisms for the test process, the filter classes can only be compared approximately. If you translate the ‘old’ filter classes into the ‘new’ ones, you get the following:
The advantages of implementing DIN EN 16798-3
Implementing ventilation concepts and solutions in accordance with DIN EN 16798-3 offers many advantages. Highly effective filters help protect people from a wide variety of pollutants and harmful gases. The efficiency of a filter also impacts operating costs: 80 percent of the total costs of the filter are attributable to energy. A clean filter accounts for 25 percent of the energy consumption of a ventilation system, whereas a loaded filter accounts for a full 50 percent.
What’s more, over the long term, efficient ventilation and cooling systems enhance property value, as energy-efficient, safe buildings are increasingly in demand. Environmentally, implementing the standard results in a substantial reduction in CO2 emissions, which is invaluable when it comes to addressing the critical issue of climate change.
Practical implementation tips for improving building filtration
Implementing DIN EN 16798-3 can be challenging, especially if older systems need to be modernised or replaced. A thorough review and assessment of existing ventilation and cooling systems is a good starting point. Speaking to energy consultants for a detailed energy audit can help evaluate current systems and provide recommendations for upgrades or replacements in line with the standard. The experts at MANN+HUMMEL are available to support you with analysing the energy efficiency of your filters.
