Sustainability has been a central part of our corporate philosophy at Aeris from the very beginning. Our commitment to making environmentally conscious decisions is particularly evident at our energy-efficient production facility in Horgau.
For the further expansion of our production facility, we receive state support as part of the KfW funding program. In this article, we explain what exactly the funding entails and why we chose the higher KfW classification.
Sustainable construction – what’s behind KfW funding?
KfW funding supports energy-saving construction projects and sustainable renovations such as photovoltaic systems, heat pumps, and modern thermal insulation.
The KfW banking group is a state-owned promotional bank known for its extensive financing programs aimed at mitigating the economic and social impacts of the COVID-19 crisis and supporting ecological and digital progress.
KfW funding, particularly in the area of efficient buildings, is part of the German Recovery and Resilience Plan (DARP). This plan is financed by European Union funds under the Recovery and Resilience Facility (RRF) of NextGenerationEU.

Funding for the future: The importance of KfW standards
KfW 85, 75, 55, 40 (EE), (NH) and Plus – What do all these KfW standards actually mean?
In short, KfW efficiency classes indicate how energy-efficient a building is: The lower the number, the more energy-efficient and environmentally friendly the building.
Why we opted for the KfW 40 standard:
Because we are committed to sustainable and energy-saving production, we deliberately chose one of the highest KfW classifications for the expansion of our production facility in Horgau. State funding for this standard allows us to invest even more in sustainable technologies in the future.
Sustainably ahead: Our Aeris energy-efficient building
Our production facility in Horgau demonstrates that at Aeris, we have been committed to a sustainable future from the very beginning.
As early as 2007, when renewable energies were not yet a widespread topic, we already relied on photovoltaics. In recent years, we have expanded the solar systems on our roofs to such an extent that we now generate more electricity than we consume ourselves. We feed the surplus into the public grid, supplying additional households with electricity.
This goes hand in hand with the KfW's photovoltaic funding, which specifically promotes the use of renewable energies.

We also rely on innovative thermal insulation and efficient air-source heat pumps, the use of which is also funded by KfW.
The new, light-filled extension is heated and ventilated by concrete core heating and a powerful ventilation system. We generate the necessary heat with 2 large air-source heat pumps and a combined heat and power unit. These technologies ensure minimal energy consumption and maximum energy efficiency.
Although we have doubled our production area and expanded our storage area by 1/3, we now consume less energy than before. Our headquarters in Haar also follow this line: Here, too, we are 100% supplied with renewable energies.
Our path into the future
Through advanced, energy-efficient construction methods and the use of innovative technologies, we are setting new standards and contributing to ecological change in Germany. We are proud to have implemented the high KfW standard and to have built a forward-looking, sustainable building with our production facility in Horgau.
