Ventilation market

Lüftungsmarkt und die dezentrale Lüftung

Ventilation market

The controlled living space ventilation can be divided into three large sub-areas:

  • Decentralized ventilation systems with heat recovery
  • Central ventilation systems with heat recovery
  • Exhaust systems without heat recovery

    In terms of history, decentralized ventilation systems with heat recovery represent the latest development on the ventilation market. The first decentralized ventilation units were brought to market maturity in the 1990s and the technology has been successively developed and improved since then. Based on experience and learning curves, the manufacturers and providers from the early days to this day are leaders in this segment.

    If you compare the three sub-areas, decentralized ventilation solutions enjoy significant advantages, growing acceptance and popularity on the ventilation market. In recent years, decentralized ventilation systems have therefore recorded strong growth rates in the double-digit range, in which market shares were also taken over by central ventilation systems. In terms of volume, even more decentralized than centralized ventilation devices are now being sold. Architects / planners, installers and users particularly appreciate the simplified installation of decentralized ventilation devices, as well as user maintenance without specialist companies and the energy savings thanks to low power consumption and high heat recovery. The market itself is characterized by a high rate of innovation and a large number of newcomers, with the majority of the market being dominated by a few established system providers. In an international comparison, innovations and new technologies are accepted at different rates in the individual country markets. Due to their market structure, certain countries are more willing to accept innovations and innovations than others. In terms of decentralized ventilation, Germany is the “lead market” and has the highest number of decentralized systems in an international comparison. The following guides give you an overview of important areas in the German ventilation market.

    EnEV - The Energy Saving Ordinance

    The thermal protection and heating systems ordinance was combined by the EnEV, it is considered a means of energy and climate protection policy in Germany. Within the scope of this, the EnEV regulates the permissible personal requirements of heated and air-conditioned rooms and includes obligations for energy-efficient renovation for homeowners. With regard to the scope of the requirements, a distinction is made between the construction of a new building and the renovation of an existing building. Here you will find extensive information on the Energy Saving Ordinance.

    DIN 1946-6 - Air exchange rate in living rooms

    Modern building facades are very tight due to today’s construction, which means that there is insufficient air exchange with the usual ventilation behavior. This lack of air exchange can, however, have significant consequences such as moisture damage, mold growth or even the accumulation of pollutants. In order to ensure a sufficient exchange of air, DIN 1946-6 shows various possible solutions. Here you will find specific provisions of DIN 1946-6.

    DIBt approval & TÜV testing of ventilation devices

    The German Institute for Building Technology (DIBt) is the approval body for non-regulated building products and types and also issues specifications for mechanical ventilation devices. These specifications relate to various criteria such as the dimensions and the air volume flow of the device. The TÜV inspects the aforementioned criteria, which ultimately also forms the basis for the DIBt approval of the inVENTer ventilation units. Further information can be found in the guide to TÜV testing and DIBt approval of ventilation units.

    The energy efficiency label for ventilation systems

    The energy efficiency label uses colored efficiency scales to show the energy consumption of products and makes it easier for buyers to choose energy-efficient products. In the case of residential ventilation systems, labeling with the energy efficiency label has been mandatory since the beginning of 2016. The best efficiency class for ventilation systems is A + and the worst G, whereby these classes describe how much energy can be saved by the ventilation device compared to window ventilation. All inVENTer ventilation systems achieve energy efficiency class A. In combination with a sensor or the MZ-One controller, various models are even classified in efficiency class A +. Read everything about the energy efficiency label for ventilation systems and the classification of inVENTer’s decentralized ventilation systems in our article.
