Nowadays, sustainability is becoming increasingly important in the construction industry. Green construction projects that focus on environmental compatibility and energy efficiency are on the rise. A key aspect in the planning and implementation of such projects is ensuring optimal air quality inside buildings. This is where decentralized ventilation systems come into play, enabling efficient and environmentally friendly ventilation.
The term “decentralized ventilation” may seem abstract at first glance, but it holds enormous potential for sustainable construction. These innovative systems not only provide a supply of fresh air, but also help to reduce energy consumption and thus improve the carbon footprint.
In the following article, we take a closer look at the importance of fresh air for green construction projects and highlight the advantages and functionality of decentralized ventilation systems. Learn how this technology helps to optimize standards in sustainable construction and what impact it has on the environmental balance.
Fresh air is a crucial element for the well-being and health of a building’s occupants. The quality of indoor air is becoming increasingly important, especially in sustainable construction projects. Decentralized ventilation systems play a crucial role in ensuring a constant supply of fresh air.
Sustainable construction projects focus not only on energy efficiency, but also on the well-being of users and protection of the environment. Decentralized ventilation systems enable controlled ventilation of rooms without having to make major changes to the building structure. This not only contributes to a healthy indoor climate, but also supports the energy efficiency of the building.
The use of decentralized ventilation systems in sustainable construction projects makes it possible to implement individual ventilation solutions that meet the specific requirements of the building. Targeted control of the air supply not only increases the comfort of the occupants, but also optimizes energy consumption.
Decentralized ventilation systems offer the possibility of regulating air exchange according to demand, thus ensuring a continuous supply of fresh air. This not only contributes to the health and well-being of the occupants, but also to the sustainability of the construction project as a whole.
Overall, the importance of fresh air for sustainable construction projects is undisputed. The use of decentralized ventilation systems can improve indoor air quality, reduce energy consumption, and thus make an important contribution to holistic sustainable construction.
Decentralized ventilation systems play a crucial role in sustainable construction, as they enable efficient and demand-based ventilation of rooms. In contrast to central ventilation systems, which cover an entire building, decentralized ventilation systems work room by room and independently of each other.
These systems are based on the principle of controlled air exchange. The ventilation units continuously extract stale air and simultaneously supply fresh outside air. This process is demand-driven and ensures optimal air quality in every room.
An important component of decentralized ventilation systems are the integrated filters that filter pollutants and pollen out of the supply air. This not only improves air quality, but also protects the health of the occupants.
The use of modern fans with heat recovery also makes energy efficiency a top priority. The heat from the exhaust air is used to preheat the fresh air supplied, which leads to a reduction in energy consumption.
The flexible installation and modular design of decentralized ventilation systems enable a customized installation that is optimally tailored to the requirements of the respective construction project. This means that both new buildings and renovation projects can be equipped with sustainable ventilation solutions.
All in all, decentralized ventilation systems offer an efficient and environmentally friendly solution for sustainable construction by ensuring controlled air circulation, high energy efficiency, and improved quality of life in the rooms.
In Germany, there are a number of requirements and legally binding obligations aimed at promoting sustainable construction and reducing energy consumption and environmental impact in the building industry. These regulations are enshrined at various legal levels, from national laws to European directives. Here are some of the most important ones:
1. Building Energy Act (GEG)
The Building Energy Act, which has been in force since November 2020, combines the previous regulations from the Energy Saving Ordinance (EnEV), the Energy Saving Act (EnEG), and the Renewable Energy Heat Act (EEWärmeG). It regulates:
2. Renewable Energy Sources Act (EEG)
The EEG promotes the use of renewable energies in the electricity sector. Regulations that are relevant to buildings include those concerning the feed-in of electricity from photovoltaic systems on roofs. The EEG also regulates the remuneration for the electricity fed into the grid.
3. Federal Immission Control Act (BImSchG)
The BImSchG and the associated ordinances (e.g., 1. BImSchV) regulate, among other things, emissions from heating systems. There are requirements for the use of low-emission fuels and for compliance with limit values for pollutant emissions.
4. Building regulations of the federal states
The building regulations of the individual federal states contain specific requirements for the planning, construction, use, and demolition of buildings. These may include additional requirements for thermal, sound, and fire protection as well as accessibility. Some federal states have also introduced special regulations to promote sustainable construction.
5. Ordinance on energy-saving thermal insulation and energy-saving building services in buildings (EnEV)
Although the EnEV has now been replaced by the GEG, it is historically an important basis for the development of energy requirements for buildings. Many of its specifications have been incorporated into the GEG.
6. Climate Protection Act (KSG)
The Climate Protection Act sets out the framework conditions for reducing greenhouse gas emissions in Germany. It formulates emission reduction targets that also affect the construction sector, in particular through requirements for energy efficiency and the use of renewable energies.
7. DIN standards and technical guidelines
In addition to legal requirements, there are a number of DIN standards and technical guidelines that define specific requirements for the planning and execution of buildings. These standards include requirements for thermal insulation, ventilation technology, and sustainable building materials.
These requirements and obligations ensure that new buildings and renovations in Germany are becoming increasingly energy-efficient and environmentally friendly. It is important that builders, architects, and planners inform themselves about these legal requirements at an early stage in order to meet all requirements.

In Germany, there are a variety of subsidy options and support programs for green construction projects that aim to promote sustainable construction and support the transition to more environmentally friendly building methods. Here are some of the most important subsidy options:
1. KfW funding programs: The Kreditanstalt für Wiederaufbau (KfW) offers various funding programs for energy-efficient construction and renovation:
2. BAFA subsidies: The Federal Office of Economics and Export Control (BAFA) offers support for:
3. Funding from federal states and municipalities: Many federal states and municipalities offer their own funding programs for sustainable construction. These can include grants for energy-efficient renovations, the construction of passive houses, or the installation of solar systems.
4. Tax breaks: There are various tax incentives for energy-efficient renovations, such as tax deductibility for tradesmen’s services or special depreciation options.
5. Subsidies for electric mobility: Additional subsidies may be available for construction projects that also integrate charging infrastructure for electric vehicles.
6. EU funding: In addition to national programs, there are also subsidies at the EU level, such as those provided by the European Regional Development Fund (ERDF), which support projects related to energy efficiency and the use of renewable energies, among other things.
7. Private sector subsidies: Some banks, energy suppliers, and foundations offer their own subsidy programs or low-interest loans for sustainable construction projects.
It is advisable to contact the respective funding agencies at an early stage, as conditions and subsidy amounts may vary. An energy consultant can also provide valuable support in identifying and applying for suitable subsidies.
