Accompanying scientific research – Energiewendebauen

In order to support the networking of all projects funded by the German Federal Ministry for Economic Affairs and Energy in the “Energy in buildings and districts” research area, the accompanying scientific research works as an interdisciplinary research team.

A team led by Prof. Dr. Dirk Müller from RWTH Aachen University is analysing the many technology-based research and pilot projects in the “Energy in buildings and districts” research area and is preparing the results and findings across projects and in a methodically secure manner. A large, scientific database is being used to develop answers to very concrete and practical issues relating to energy-optimised buildings, energy-efficient districts as well as heating and cooling networks.

The researchers from five institutions are focussing on providing systematic quality assurance in the research. Together with all the stakeholders, they want to explore how successful research approaches can be translated more quickly into practice. In addition to purely technical and economic aspects, they also want to analyse the underlying socio-economic conditions. This is because a project’s success, the transferability of the findings and their broad impact are not determined solely by the technology or the tools used.

Together with the researchers in the numerous projects, the accompanying research is aiming to identify and assess important findings, promote knowledge and the sharing of findings, as well as identify synergies and important trends in research and technology.


The accompanying research is focussing on four main tasks: First of all, based on projects and discussions, it is intended to identify research issues relating to building energy technology. In addition, there will also be a data-based trend analysis, which will provide the basis for evaluating current technical developments and their possible potential: What is already being intensely developed and researched? Which issues will be important in the future? The answers to these will identify both trends and the technologies required in the future building sector.

How can individual solutions be combined to form an efficient overall system? What can we learn from the sum of all the projects? A systematic, inter-project analysis of all the research topics aims to answer these questions. In addition, a revised reporting system aims to ensure greater transparency and more widespread replication of the research results.
