Why proper ventilation is important

The topic of ventilation is often underestimated, yet the air quality in closed rooms plays a decisive role in our well-being and health. Proper ventilation is not only important for fresh air, but also for regulating humidity and preventing mould growth. Regular ventilation ensures a pleasant indoor climate that has a positive effect on both our concentration and our sleep. Correct ventilation is becoming increasingly important, especially in times when buildings are becoming better and better insulated. Without sufficient air circulation, pollutants, odours and humidity can build up in rooms, which can cause health problems in the long term. A well-ventilated room, on the other hand, promotes well-being and prevents health problems. When planning a ventilation concept, it is important to consider not only the right technology, but also the individual needs of the occupants. Every room and every person has different requirements in terms of air quality, which can be optimally met by a customised ventilation system. The right duration and frequency of ventilation are crucial for a healthy indoor climate. Experts recommend fully ventilating rooms for at least 3-5 minutes to exchange stale air. The frequency of ventilation should be every 2-3 hours, depending on the size of the room, number of people, outside temperature and humidity. Rooms with many people in particular should be ventilated more frequently in order to reduce the CO2 concentration. In winter, short pulse ventilation with wide open windows is more efficient and energy-saving than long ventilation with tilted windows. Regular and correct ventilation improves well-being and energy efficiency while preventing mould growth.  

Manual ventilation is good: a ventilation system is better

In addition to conventional methods and tips for proper ventilation, such as pulse ventilation or cross ventilation, ventilation systems are playing an increasingly important role in ensuring a healthy indoor climate and the energy efficiency of a building. Controlled ventilation is essential, particularly in well-insulated and airtight rooms, in order to effectively remove humidity, pollutants and CO2 to the outside and at the same time supply fresh air. The ventilation system ensures that a constant exchange of air is guaranteed without the rooms cooling down or heating costs rising enormously. Both passive and active ventilation systems offer possible solutions. Both types offer specific advantages and contribute significantly to the quality of indoor air. Modern ventilation systems have heat recovery systems that utilise the heat from the exhaust air to preheat the fresh air supplied, resulting in significant energy savings.

Passive ventilation systems

Passive ventilation systems utilise natural forces such as wind pressure and thermal buoyancy to draw fresh air into a building and remove stale air. Here are some features and benefits of these systems:

1. Energy efficient: as passive ventilation systems require no mechanical parts, they use no electrical energy, making them an extremely energy efficient solution.
2. Low maintenance: With fewer moving parts and mechanical components, passive ventilation systems are generally lower maintenance and more durable.
3. Constant supply of fresh air: Passive systems provide a continuous supply of fresh air, which is particularly important in well-insulated buildings where natural air exchange is minimised.
4. Environmentally friendly: By utilising natural ventilation forces, passive systems contribute to a reduction in the CO2 footprint.

Active ventilation systems

Active ventilation systems, also known as mechanical ventilation systems, use fans and other mechanical components to control the supply and exhaust of air. These systems offer several advantages that contribute to improving indoor air quality.

1. Controlled air exchange rate: Active ventilation systems allow precise control unit of the air exchange rate, which is particularly beneficial in densely populated or heavily utilised spaces.
2. Heat recovery: Many modern active ventilation systems are equipped with heat recovery functions that utilise the heat from the exhaust air to preheat the fresh air. This results in a significant reduction in heating energy requirements.
3. Air filtration: Mechanical ventilation systems can be equipped with filters that remove pollutants, allergens and other contaminants from the air, which contributes to a significant improvement in air quality.
4. Automation and intelligence: Modern active ventilation systems can be equipped with sensors and intelligent control systems that automatically adjust the ventilation output based on the current air quality conditions and room utilisation.

Both passive and active ventilation systems therefore offer effective solutions for ensuring good indoor air quality. Passive systems are particularly attractive due to their energy efficiency and low maintenance requirements, while active systems score highly thanks to their precise controllability and additional functions such as heat recovery and air filtration. In combination with proven ventilation techniques, these systems can make a significant contribution to maintaining a healthy and comfortable indoor climate and should therefore always be included in ventilation planning to ensure that the indoor air is fresh, clean and pleasant at all times. A well-planned and professionally installed ventilation system can help to create a healthy and comfortable indoor climate that protects both the occupants and the building itself. Integrating 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. We are happy to support you right from the initial phase of the planning process to ensure that the ideal customised ventilation solution can be implemented together with you. Provide us with your planning documents and we will support you from the start of your project through to handover and deliver the required solutions in the form of your customised Ventomaxx ventilator.  

When should the ventilation concept be created?

The creation of a ventilation concept should be incorporated into the planning process of a building project as early as possible. 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 very important for renovation projects in order to find the best possible solution for the individual circumstances.

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:

1. 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.
2. 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.
3. Calculation of air volume flows: Precise calculation of the required air volume flows is essential to ensure efficient air circulation and fresh air supply.
4. Integration of sound insulation measures: Sound Insulation is an important factor in ventilation design, especially in noise-sensitive environments. The selection of sound-insulated fans and suitable positioning are crucial here.
5. 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.
6. Integration of air filters: The integration of air filters into the ventilation concept ensures optimum air quality and protects against pollutants and allergens.
7. 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.
