Understanding and applying the DIN 1946-6 ventilation concept

 

Main objectives of the DIN 1946-6 standard

The DIN 1946-6 standard deals with the ventilation of residential buildings and defines the minimum requirements for room ventilation technology. Its main objective is to ensure a healthy and comfortable indoor climate in homes. Compliance with this standard is intended to improve the air quality and increase the well-being of the occupants.

The relevance of DIN 1946-6 for the planning and realisation of building projects is considerable, as this standard defines essential requirements and guidelines for the ventilation of residential buildings. The most important aspects that emphasise its significance are Ensuring air quality, avoiding structural damage, fulfilling legal requirements, energy efficiency, planning reliability, flexibility and user comfort.

Among other things, DIN 1946-6 specifies how the ventilation systems in residential buildings should be planned, designed and operated. It also defines various ventilation concepts, such as needs-based ventilation or ventilation for moisture protection, in order to cover different requirements.

Another important aim of the standard is to promote energy efficiency and optimise the energy consumption of ventilation systems. Compliance with DIN 1946-6 can also protect residential buildings from moisture damage, as it ensures correct ventilation and thus prevents mould growth.

It is crucial that planners, architects and contractors are fully aware of and implement the requirements of DIN 1946-6 to ensure that ventilation systems function properly and do not jeopardise the health of residents.

 

 

Definitions of terms according to DIN 1946-6

An important term according to DIN 1946-6 is "nominal ventilation". This refers to the air flow of outside air that is required for the normal ventilation of rooms. Nominal ventilation is a decisive parameter in the design of ventilation systems, as it forms the basis for calculating the required air volume.

Another important term is the "fresh air volume flow". This refers to the amount of fresh air that is introduced into a room per unit of time. The fresh air volume flow rate is decisive for the air quality in a room and must be calculated in accordance with the specifications of DIN 1946-6.

Other terms used in the DIN 1946-6 standard include "moisture protection (FL)" and "reduced ventilation (RL)". Moisture protection is an important aspect of preventing mould growth in rooms, while reduced ventilation is a way of reducing energy consumption when rooms are not in use. An additional term is "intensive ventilation (IL)", which means increased ventilation that is necessary for special requirements in order to compensate for high levels of indoor air pollution in the short term, for example when cooking or for rapid air exchange when there are many people in the room.

It is crucial to understand the definitions of these terms in accordance with DIN 1946-6 in order to create an efficient ventilation concept for homes that complies with the standards.

 

 

Difference between DIN 1946-6 and DIN 18017-3

DIN 1946-6 and DIN 18017-3 are two important standards in the field of ventilation technology that are often confused. However, it is important to understand their differences in order to implement the respective requirements correctly.

DIN 1946-6 specifies the minimum requirements for the ventilation of flats and residential buildings. It concerns general ventilation, hygienic requirements for air quality, protection against mould growth and moisture as well as energy consumption for ventilation.

In contrast, DIN 18017-3 deals specifically with the ventilation of non-residential buildings, such as office buildings, schools or hospitals. This standard also specifies requirements for air quality and air exchange, but takes into account the specific needs and uses of these buildings.

An important difference also lies in the calculation methods for the air exchange: while DIN 1946-6 specifies the minimum air exchange depending on the utilisation, DIN 18017-3 specifies concrete requirements for the air volume flow depending on the rooms and number of people.

It is advisable to take both DIN 1946-6 and DIN 18017-3 into account when planning and implementing ventilation systems in order to fulfil the respective requirements and ensure a healthy indoor climate.

 

Explanation of the term "increased requirements" in the context of the DIN 1946-6 standard

In the context of DIN 1946-6, the term "increased requirements" refers to special situations that require more intensive ventilation. This is necessary in the case of increased moisture or pollutant levels, low natural air exchange rates, special user requirements (e.g. for sensitive people) or in rooms used for specific purposes (e.g. kitchens, bathrooms). In order to fulfil these requirements, measures such as intensive ventilation, the use of adapted ventilation systems and careful planning and implementation of the ventilation systems are used to ensure sufficient air quality at all times.

 

Why is the creation of a ventilation concept required and who has to take care of it?

The creation of a ventilation concept in accordance with DIN 1946-6 is of crucial importance for indoor air quality and energy consumption in buildings. A well-founded ventilation concept can not only take into account health aspects, such as the prevention of mould growth and the reduction of pollutants in the air, but also achieve energy savings.

Building owners and planners are primarily responsible for drawing up the ventilation concept. They must ensure that the requirements of DIN 1946-6 are met. Architects, technical building services planners and energy consultants play an important role here, as they must integrate the ventilation concept into the overall planning of the building and ensure its technical implementation.

A ventilation concept is particularly important for new buildings, but also for refurbishments and conversions. It ensures that the ventilation system is optimised to meet the requirements of the building and that the occupants are supplied with fresh air without consuming unnecessary amounts of energy.

It is therefore essential that all parties involved address the issue of ventilation concepts at an early stage and ensure that the requirements of DIN 1946-6 are met in order to guarantee a healthy and energy-efficient indoor climate.

 

Consequences of non-compliance with DIN 1946-6: Health, structural and legal risks

Non-compliance or misinterpretation of DIN 1946-6 can have considerable health and structural consequences. Inadequate ventilation installs poor indoor air quality, which can cause health problems such as respiratory diseases and allergies in the occupants. It can also lead to moisture problems and mould growth, which can damage the building fabric in the long term and make expensive repairs necessary.

There may also be legal and financial consequences. Building projects without compliance with the standard may not receive approval or may lose existing approvals. Builders and planners could be held liable, which could install legal disputes and claims for damages. The property could lose market value and insurance companies could refuse to cover damages. In addition, inefficient ventilation systems can increase energy consumption and affect living comfort, resulting in subsequent refurbishment costs.
