Ventilation in multi-storey buildings is a topic that raises many emotions, especially in the context of buildings that have underground garages. Such spaces require special attention to the design of ventilation systems, as the introduction of adequate airflow in such spaces can make a huge difference to the health and comfort of the occupants. In addition to their role of storing vehicles, underground garages also act as storage for exhaust fumes, moisture or pollutants that must be effectively removed from the space.
The importance of ventilation in underground garages
Underground garages are an essential part of the infrastructure of many modern buildings, especially in cities where construction space is limited. In such facilities, vehicles not only park but also work, generating fumes, moisture and heat that can negatively affect air quality. In the absence of adequate ventilation, these pollutants can accumulate in the garage, which not only compromises the comfort of those using the space, but can also lead to health risks. For example, high concentrations of carbon monoxide or other gases can lead to serious health problems and, in extreme cases, even poisoning.
This is why it is so important that the ventilation in such spaces is not only efficient, but also properly designed. In many cases, designers are faced with spatial, architectural and technical constraints that can hinder the proper planning and installation of a ventilation system. In addition, changing air quality regulations and growing environmental awareness are forcing the use of modern technologies that enable efficient air exchange without unnecessary energy loss.
Challenges in designing a ventilation system
Designing a ventilation system in buildings with underground garages presents many challenges. One of the most common problems is limited space, which makes it difficult to position the ventilation ducts and other necessary system components. In residential or office buildings, designers are often faced with the need to integrate garage ventilation with other building systems, which requires adequate distances to ensure that the building structure is not compromised or its aesthetics are not affected. Often, limited space in underground garages also means that smaller ventilation units need to be used, which can affect their efficiency.
Another challenge is airflow. Ventilation of underground garages must be designed to ensure adequate air circulation in every corner of the space. For this reason, special attention must be paid to the proper location of air inlets and outlets. Inappropriate placement of these can lead to localised air stagnation that promotes the accumulation of pollutants in specific locations, increasing the risk of adverse health conditions. These problems can be exacerbated in buildings that do not have natural vents and all systems must be designed and constructed artificially.
Modern solutions in underground garage ventilation
Modern ventilation systems offer a number of solutions that can help overcome the difficulties associated with installing ventilation in underground garages. One of the most popular solutions is mechanical ventilation with heat recovery, which allows polluted air to be efficiently removed from the garage while using thermal energy. As a result, the system not only improves air quality, but also saves on heating costs. The introduction of such ventilation systems allows for a reduction in energy consumption, which is particularly important in an era of rising energy prices and an increasing emphasis on a green economy.
Another solution that can prove effective is the use of hybrid ventilation, combining natural and mechanical systems. In this case, natural airflow is used in those parts of the building where this is possible, and mechanical systems are switched on when natural ventilation is insufficient. This type of solution provides energy savings, but at the same time maintains the air quality in the garage. This is important because ventilation systems based on renewable energy are becoming increasingly popular and their installation in buildings with underground garages is a good way to improve the energy efficiency of the building.
Recommendations for investors and users
Investors planning to install ventilation in buildings with underground garages should pay particular attention to several aspects. Firstly, it is advisable to opt for ventilation systems that are able to adapt to changing conditions in the garage, for example depending on the number of vehicles or the degree of air pollution. Secondly, you should consult experienced specialists who are knowledgeable about the latest technologies and solutions in this field. Ventilation in an underground garage is a topic that requires precise planning, as an inadequately designed system may fail to fulfil its functions and, in extreme cases, create additional risks for the building’s users.
Furthermore, it is important that the ventilation system is regularly serviced and checked for efficiency. If damaged or contaminated, the ventilation can lose its effectiveness, which can lead to serious air quality problems in the garage. It is also worth bearing in mind that buildings with underground garages may need to have monitoring systems in place to keep an eye on the air quality in these spaces.
In summary, the installation of ventilation in buildings with underground garages is a complex process that requires the consideration of a number of factors, such as space, technology, regulations or energy efficiency. By using modern solutions, such as mechanical ventilation with heat recovery or hybrid ventilation systems, it is possible to create an efficient system that provides a healthy and comfortable environment in such spaces.
