In the STABLE research project, an energy concept for the German multi-family housing stock that is both climate-friendly and socially acceptable is to be developed.

The decision of the federal government to achieve climate neutrality in Germany by 2045 increases the pressure to replace fossil fuels and further advance climate-friendly solutions for the building sector. In this context, the STABLE research project aims to develop an energy concept for the German multi-family housing stock that is both climate-friendly and socially acceptable. Key to the success of innovative concepts is both the promotion of acceptance among tenants and the demonstration of their own opportunities for behavioral change through dialogues and active participation during the planning and implementation of measures. This is where the STABLE project comes in, as it aims to develop a procedural framework for involving all stakeholders (landlords, tenants, energy supply companies, network operators, municipalities, sponsors, etc.) with innovative dialogue formats that are designed, tested and made transferable.


Specifically, the project will scientifically accompany the renovation of a real multi-family house from planning through implementation to operation, with socially just climate neutrality being the top priority. The scientific accompaniment of the implementation ensures that existing barriers to the socially acceptable transformation of the building stock are recognized and solution strategies are developed.
The project consortium brings together the necessary experts from science and practice over the project period, thus creating a procedural framework for a socially accepted energy transition in the building sector. The continuous involvement of all stakeholders through quantitative and qualitative dialogue and participation formats ensures that the transformation takes place in the interest of society, which ensures long-term success.
As a basis for the development of a climate-friendly and socially acceptable energy concept, regulatory, economic and technical framework conditions are worked out in the project. The aim is to meet the challenge of rising financial burdens on tenants in the context of climate policy goals and future developments in energy markets. In addition, technologies for a climate-neutral energy concept and possible operating models (e.g. tenant electricity) for these technologies, including corresponding tariffs, will be analyzed.

Based on the resulting requirements for a climate-neutral and socially acceptable multi-family house, a technology selection and corresponding dimensioning will be identified using optimization calculations. The focus is on the perspective of various actors (especially landlords and tenants) in order to investigate the influence of the conflict between investment and operating costs in rental relationships.
After selecting the technologies, an energy management concept will be developed that enables the integration of innovative operating models and the involvement of tenants through user-machine interfaces.
After simulation testing, the developed concepts will be transferred to practice and applied as part of the energy renovation of a real multi-family house. This enables both a holistic examination of the real energy system and the integration of all relevant stakeholders throughout the entire planning to implementation process.
