Design of the building ventilation

One of the most important stages of the design of the general complex of engineering networks of the building is the design of ventilation. It is ventilation that helps to create a healthy and comfortable microclimate in a residential or public space, and to ensure the safety and stability of all technological processes in industrial and technical buildings. However, it causes almost more difficulties than all other systems taken together.

Designing the ventilation of residential buildings is the key to future comfort, which today can be achieved only with the help of modern technologies. The design of this engineering system in a private house has a lot of features, depends on the climate in the region and the features of the building design, can include both ventilation systems, including through windows, and air ducts and electric hoods. The most rational ventilation design solutions for each house are selected individually and depend on many factors.

Our task as a company is to find an ideal balance between natural ventilation and additional auxiliary systems.

House ventilation project

The design of ventilation networks of residential buildings has always required attention, but strict regulatory requirements began to be imposed relatively recently. When creating a building ventilation project , we pay attention not only to the features of the building design, but also to the materials from which its external and internal parts are made or will be made - this allows us to achieve the best result.

The design of the ventilation system in a private house is connected with many factors. For example, traditional wooden buildings breathe by themselves and leave a lot of opportunities for air flow. With the advent of more modern materials, such as brick, concrete and various types of foam blocks, the requirements for natural ventilation in the design of the house have changed, now installers and engineers need to consider many more factors and look for convenient ways of organizing ventilation to avoid the formation of excessive humidity in the house and the appearance of mold and other types of fungi, therefore, even small houses may require the installation of ventilation networks.

Hermetic windows are installed everywhere today - it preserves heat, but greatly increases humidity inside the building, therefore it is quite difficult to professionally and qualitatively design a ventilation system in modern even small private houses with such windows, and in large apartment buildings and large office buildings, the negative effect of hermetic windows is even more manifested.

To save the situation, as part of the design of the ventilation system of various types of buildings, we create supply channels to ensure stable air circulation

The modern ventilation project also takes into account the reduced level of vapor permeability of materials - insulation, clinker, vapor barriers. Natural removal of moisture under the condition of using such materials is reduced even more, therefore, designing a ventilation system, whether for a modern apartment building or a cottage, requires a more significant list of preparatory work than it may seem at first glance, so it is critically necessary to entrust this task to an experienced team, whose professionals will take into account all these nuances and you will get an impeccable result.

Norms of air exchange for the building ventilation project

Current regulations fully regulate air exchange norms, which are relevant for ventilation projects of both large high-rise or industrial buildings and small buildings of various purposes.


  • in residential premises of buildings it is 3 m3 / h per 1m2;
  • ventilation design for an apartment building implies standards for technical and non-residential premises as well - if there are no people in the room, the air exchange should be at least 0.5 m3 / h per 1 m2;
  • Clean air and regular exchange are also important.

Building regulations do not take into account all factors, so it is worth entrusting the design of ventilation to professionals in order to guarantee a good result and comfortable conditions for the life or work of people who will be in the building.

From the materials of the article described above, we have already understood that the design of the ventilation system , whether for a high-rise building or a small private house, is not only a matter of comfort, normal functioning and durability of the building, but also the health of residents or workers. Each project that we develop takes into account necessarily all the nuances - from the material of the walls to the weather conditions of the region and can be built on the basis of different types of ventilation or include several types of ventilation systems at once.

For example, the ventilation and air conditioning project of a high-rise building may include the following types of ventilation:

  • natural;
  • mechanical - hood is used;
  • combined - when the inflow is natural, and hoods are used for the return flow.

Offices usually require similar ventilation systems as residential buildings, but special warehouses and industrial production buildings very often need to supplement natural ventilation with powerful hoods and filters to ensure rapid air exchange in conditions of rapid pollution.

Our specialists create projects for any high-rise, low-rise and private one-story buildings, as well as offices or industrial buildings, focusing on the individual characteristics and all the non-obvious nuances of each project.
