As an MEP planner or architect, it is crucial to understand the intricacies and requirements of ventilation systems in order to achieve optimum results. From centralised to decentralised ventilation concepts, there are many aspects to consider to ensure effective air circulation and a comfortable indoor climate.

Why is a ventilation concept so important and who should create it? In this article, we will explore the core elements of a successful ventilation concept and provide tips on how building services planners and architects can optimise the air quality in buildings. Find out when it is best to create a ventilation concept and which steps are essential for planning. Immerse yourself in the world of ventilation concepts and learn how you can achieve the best possible result through targeted planning and implementation.

What is a ventilation concept and why is it important?

A ventilation concept is a crucial part of any construction project that ensures optimum ventilation and air quality in a building. It refers to the planning and implementation of various ventilation systems that are crucial for the health and well-being of the occupants.

A well-designed ventilation concept takes into account aspects such as air volume, air quality, the type of ventilation system, energy efficiency and sound insulation. It ensures that sufficient fresh air is supplied and stale air is extracted to guarantee a comfortable and healthy indoor climate.

By implementing a ventilation concept, numerous problems associated with inadequate ventilation can be avoided. These include moisture problems, mould growth, unpleasant odours, air pollutants and an unpleasant indoor climate.

The importance of a ventilation concept is becoming increasingly important in modern construction, as buildings are becoming ever more airtight due to energy standards. Efficient ventilation is therefore crucial in order to improve living comfort and protect the health of residents.

As a building services engineer or architect, a sound understanding of ventilation concepts is essential to ensure that the planned buildings have effective ventilation systems that meet individual requirements.

Why does a ventilation concept need to be created?

Health and comfort for occupants:

A ventilation concept must be drawn up to fulfil a number of important requirements and objectives that serve both the structural and health aspects of a building. Controlled air circulation removes moisture, pollutants and mould from the indoor air. This creates a healthy indoor climate and prevents health problems such as allergies and respiratory diseases. It ensures the continuous exchange of stale and fresh air, which reduces the concentration of pollutants, CO2 and humidity. This improves the air quality and thus the health and well-being of the occupants.

Compliance with building regulations and standards:

The creation of a ventilation concept is often required by law and must comply with applicable building regulations and standards. In order to ensure indoor air quality and protect the health of the occupants, clear guidelines for appropriate ventilation are laid down. A professionally planned ventilation concept ensures compliance with these requirements and minimises the risk of structural damage due to moisture and mould growth.

1 DIN 1946-6: Ventilation of flats

DIN 1946-6 is a central standard for the ventilation of residential buildings in Germany. It specifies the requirements for ventilation systems to ensure sufficient air quality and moisture protection.

2 EnEV and GEG: Energy Saving Ordinance and Building Energy Act

The Energy Saving Ordinance (EnEV) and the Building Energy Act (GEG) set standards for the energy efficiency of buildings in Germany. An important aspect of this is the reduction of energy consumption through efficient ventilation systems. The GEG integrates the requirements of the EnEV and the Renewable Energies Heat Act (EEWärmeG) and requires

Tightness of the building envelope: to avoid uncontrolled ventilation losses, the building envelope must be airtight.

Ventilation with heat recovery: Modern ventilation systems should be equipped with heat recovery wherever possible in order to maximise energy efficiency.

3. workplace directive (ASR A3.6)

ASR A3.6 is relevant for non-residential buildings, especially workplaces. This directive defines the requirements for ventilation in workspaces in order to ensure the health and well-being of employees. Workspaces must be adequately supplied with fresh air, whereby the air quality and CO2 content should be monitored. Ventilation systems must also be used to ensure controlled and sufficient ventilation.

4 Building regulations of the federal states

In Germany, there are different building regulations in the federal states that set specific requirements for the ventilation of buildings. These building regulations may contain more extensive provisions than the nationally applicable standards and regulations, for example on structural moisture protection. This concerns regulations to prevent moisture damage in buildings. Furthermore, ventilation systems often have to fulfil special requirements with regard to fire protection, e.g. through the installation of fire dampers.

5 Further standards and directives

In addition to the standards and regulations mentioned above, there are other guidelines that can have an influence on ventilation concepts, such as VDI 6022, a guideline on hygiene requirements for ventilation systems and equipment, which is particularly relevant in public buildings and workplaces.

In addition to compliance with standards and legal obligations, there are of course other good reasons for a ventilation concept:

Energy efficiency:

An efficient ventilation concept can contribute significantly to improving the energy efficiency of a building. Heat loss can be minimised through targeted ventilation with modern ventilation systems. This leads to a reduction in heating costs and lower energy consumption. Good air circulation in the rooms also helps to distribute the temperature evenly and ensures a pleasant indoor climate. Modern ventilation systems such as the solutions from Ventomaxx can be equipped with heat recovery, which utilises the heat contained in the exhaust air to preheat the fresh air. This saves heating energy and reduces energy costs. A targeted ventilation concept also ensures that energy losses are avoided. It prevents uncontrolled heat loss through leaks and windows, which increases the energy efficiency of the building.

Sustainability and value retention of the property:

A well thought-out ventilation concept is also very important in terms of sustainability and maintaining the value of the property. Efficient air routing and the use of modern ventilation systems can reduce energy consumption and lower CO2 emissions. This contributes to environmentally conscious building operation and ensures that the property retains its value in the long term. Good ventilation is also an important aspect for the future viability and sustainability of buildings. Energy-efficient ventilation reduces CO2 emissions and helps to conserve resources, which minimises the building's ecological footprint. Ventilation concepts also take into account future developments and requirements, such as climate change and rising energy standards.

Other issues are relevant with regard to maintaining the value of the property. For example, controlled ventilation protects the building fabric from moisture damage, which preserves the value of the property in the long term, and regular and sufficient ventilation helps to extend the service life of the building envelope and interior fittings.

Overall, a well thought-out ventilation concept makes a significant contribution to creating a healthy, comfortable and energy-efficient living or working environment. It is an integral part of modern building planning and refurbishment.

Who needs to create a ventilation concept?

The creation of a well thought-out ventilation concept is of crucial importance for every construction project, regardless of the size or purpose of the building. TGA planners and architects play a central role here. As technical building equipment suppliers, MEP planners are responsible for developing an efficient and targeted ventilation solution that complies with building regulations. They analyse the individual requirements of a building, take into account user behaviour, room sizes and specific conditions in order to create a tailor-made ventilation concept.

As architects, you in turn have the task of seamlessly integrating the ventilation concept into the overall construction project. You must ensure that the aesthetic aspects of the building are not compromised by ventilation systems. The challenge lies in harmonising the functionality and effectiveness of the ventilation systems with the architectural design.

When should the ventilation concept be drawn up?

A ventilation concept should be drawn up as early as possible in the planning process of a building project. Even in the early stages of construction planning, it is crucial to define the requirements for air quality, energy efficiency and user comfort. A well thought-out ventilation concept can help to ensure that all necessary air supply measures are taken into account at an early stage and integrated into the building structure. This minimises subsequent changes or costly retrofitting.

It is essential to draw up a ventilation concept at an early stage, particularly for new build projects. The requirements for indoor air quality, the necessary air exchange rate, noise emissions and the energy efficiency of the ventilation system should be precisely defined. The timely creation of a ventilation concept is also of great importance for refurbishment projects in order to find the best possible solution for the individual circumstances.

The integration of a well thought-out ventilation concept into the overall planning makes it possible to optimally coordinate the various trades and recognise potential conflicts at an early stage. This makes it possible to create an efficient and sustainable solution for the air supply that fulfils the requirements of the users and the legal requirements.

The most important steps in planning the ventilation concept

Careful planning of a ventilation concept is crucial to the success of a building project. TGA planners and architects should consider the following steps when creating a ventilation concept:

Analyse the building requirements: Firstly, the specific requirements of the building and its users must be identified. This includes aspects such as room size, intended use, number of people, noise protection and energy efficiency.

Determining the ventilation system: The appropriate ventilation system should be selected based on the requirements. Centralised or decentralised systems can be considered, depending on the conditions of the building.

Calculation of air volume flows: Precise calculation of the required air volume flows is essential to ensure efficient air circulation and fresh air supply.

Integration of sound insulation measures: Sound insulation is an important factor in ventilation planning, especially in noise-sensitive environments. The selection of sound-insulated fans and suitable positioning are crucial here.

Consideration of heat recovery: Heat recovery is an important aspect of an energy-saving ventilation solution. Systems with heat recovery reduce energy consumption and contribute to living comfort.

Integration of air filters: The integration of air filters into the ventilation concept ensures optimum air quality and protects against pollutants and allergens.

Ensuring room hygiene: Hygienic aspects such as preventing mould growth and ensuring a sufficient supply of fresh air must be integrated into the concept in order to keep the living and working environment healthy.


Further tips for TGA planners and architects

1. flexibility in planning: When designing a ventilation concept, it is important to remain flexible. Different building projects require customised solutions. Make sure that the chosen ventilation system fulfils the specific requirements of the project.

2 Utilise special solutions: Special solutions may be required in complex building projects. Be prepared to take innovative approaches to achieve optimal results. Think about how special requirements such as sound insulation or energy efficiency can be taken into account.

3. consider the room design: A well-designed ventilation concept should be seamlessly integrated into the overall design of the room. Make sure that the ventilation components are both functional and aesthetically pleasing.

4. correct positioning of the ventilation openings: The positioning of the vents plays a crucial role in the efficiency of the system. Ensure that the air flow is optimally channelled and that air is evenly distributed throughout the room.

5. regular maintenance and checks: Once created, a ventilation concept is not yet complete. It is important to carry out regular maintenance work and to check the system for efficiency. This is the only way to ensure optimum long-term performance.

6. working with reliable partners: Work with qualified suppliers who have experience and expertise in ventilation systems. A good partnership can help you find customised solutions and successfully implement your project.
