Ventomaxx The 5 most common mistakes when planning ventilation systems

Planning ventilation systems: The path to an efficient and optimally functioning ventilation system begins in the planning phase. However, mistakes are often made when planning ventilation systems, which can lead to undesirable results. In this blog post, we take a closer look at the 5 most common mistakes that can occur when planning ventilation systems and how to avoid them. Careful and thoughtful planning is crucial to ensure the smoothest possible project flow, optimal air quality and energy efficiency. Let’s dive in together and avoid the pitfalls that lurk on the way to the ideal ventilation solution.

The importance of careful planning

Careful planning of ventilation systems is crucial to ensure optimal functionality and efficiency. During the planning phase, various aspects must be taken into account, such as the required air volume, air losses, positioning of ventilation outlets and maintenance requirements. A careful analysis of the individual needs of the building and its occupants is essential to develop a customised ventilation system that works optimally. Another critical point is compliance with standards and guidelines in the field of ventilation technology. A precise knowledge of the applicable regulations is crucial in order to realise a ventilation system that complies with planning and standards. Careful planning can avoid potential errors that could lead to inefficient performance, inadequate air quality or increased energy consumption. A well-planned ventilation system not only contributes to the comfort and health of the occupants, but also to maintaining the value of the building and reducing operating costs.

Mistake no. 1: Underestimating the required air volume

Accurately calculating the required air volume is an important aspect that should not be neglected. However, this step is often underestimated. Possible consequences are an inadequate air supply and therefore an inefficient system. A common mistake is to focus solely on the size of the room. However, other factors such as the number of people in the room, the room function and potential air pollution should also be taken into account. Insufficient air volume can lead to poor air quality, which has a negative impact on the well-being of the occupants. It is important to take the time to carefully determine the required air volume for each room. Too little air volume can mean that the air is not exchanged effectively, which in turn can lead to moisture problems, bad odours and even mould. Therefore, the air volume should always be calculated according to the individual requirements and conditions of the individual project.

Mistake no. 2: Failure to take air losses into account

A common mistake in the planning of ventilation systems is the inadequate consideration of air losses. Air losses can be caused by leaks in the duct systems, incorrectly dimensioned vents or inadequate sealing. These air losses not only lead to a reduced air volume flow, but can also result in increased energy consumption and undesirable air exchange. It is important to identify all potential points for air leaks during the planning phase and to take suitable measures to minimise them. The use of high-quality, airtight materials and precise installation are crucial to avoid air leaks. Furthermore, the positioning of the ventilation outlets should be chosen so that air flows are channelled efficiently and no uncontrolled air losses occur. A precise calculation of the air volume flow in relation to duct lengths, connections and resistances is essential to ensure that the ventilation system functions optimally. Neglecting air losses can not only lead to a loss of comfort, but can also impair the efficiency and effectiveness of the ventilation system. It is therefore essential to pay particular attention to this aspect when planning ventilation systems.

Mistake no. 3: Inadequate positioning of ventilation outlets

A common mistake when planning ventilation systems is inadequate positioning of the ventilation outlets. The positioning of the outlets is crucial for effective air circulation and optimum air exchange in a building. If the ventilation outlets are not strategically placed, this can lead to uneven air distribution. Rooms that are too far away from the outlets may not receive enough fresh air, while rooms close to the outlets may have too much airflow. With this in mind, it is also important to consider the room size, the room function, the number of people in the room and other relevant factors when positioning the ventilation outlets. Careful planning and calculation are required to ensure even air distribution throughout the building. By strategically placing the ventilation outlets, you can ensure that each room is supplied with sufficient fresh air and a comfortable indoor climate is maintained. Avoid this mistake by considering the positioning of the ventilation outlets as an integral part of your ventilation planning.

Mistake no. 4: Neglecting maintenance requirements

A common mistake when planning ventilation systems is neglecting maintenance requirements. Often the maintenance of the ventilation system is not given sufficient consideration, which can lead to problems in the long term. Regular maintenance of ventilation systems is crucial to ensure optimal functionality and longevity. Dirty filters, blocked ducts or faulty fans can affect the performance of the system and, in the worst case, lead to breakdowns. It is important to include maintenance requirements in the planning of the ventilation system from the outset. This includes the selection of maintenance-friendly components, access options to all relevant parts of the system and the definition of a clear maintenance schedule. Another important aspect is the training of operating personnel or residents to ensure that regular maintenance work is carried out properly. Neglected maintenance requirements can not only lead to increased energy consumption and inadequate air quality, but also to expensive repairs.

Mistake no. 5: Not catering for individual needs

A common mistake when planning ventilation systems is not taking sufficient account of the individual needs of users. Every building and every room has specific requirements in terms of air quality and air volume. A standardised ventilation system can therefore not meet all needs. It is important to consider the individual circumstances and use customised solutions. When planning, the needs of the users should therefore be taken into account, for example with regard to allergies, odour nuisance or special health requirements. The room function also plays a decisive role – an office, for example, requires a different air quality than a bedroom. Another aspect that is often overlooked is adapting the ventilation system to the individual habits of the occupants. Some prefer a continuous supply of fresh air, while others prefer targeted ventilation intervals. By catering to these individual needs, you can increase the comfort of the occupants and ensure efficient ventilation. Ultimately, it is crucial that the design of ventilation systems is not seen as a standard procedure, but as a way of catering for the specific requirements of each project. By taking individual needs into account, mistakes can be avoided and effective, customised ventilation solutions can be created.
