Accompanying scientific research – EnEff.Gebäude.2050

In order to evaluate the funding initiative "EnEff.Gebäude.2050 - Innovative projects for the almost climate-neutral building stock 2050", the funded projects in the funding initiative will be scientifically accompanied. The Fraunhofer Institute for Solar Energy Systems ISE, the Bergische Universität Wuppertal and the Institute for Sustainable Technical Systems of the Albert-Ludwigs-Universität Freiburg are participating in the accompanying research in close cooperation.

The funding initiative and the associated accompanying research are being carried out against the background of the goal set by the German government to achieve an "almost climate-neutral building stock" in Germany by the year 2050. The initiative aims to strengthen the link between research and widespread application by funding not only new technologies but also concepts for the broad market introduction of technologies and processes that are already available on the market. The aim of the accompanying research is to use detailed information on all projects funded under the initiative to identify research priorities and opportunities for meaningful project networking at an early stage and to prepare the content of the projects for the public, the project executing agency and the funding agency in an appealing way.


First, the range of topics covered by the funded projects will be examined. This analysis serves as a basis for the identification of existing thematic gaps in order to achieve the goal of an "almost climate-neutral building stock". To this end, the technologies used and the objectives of the funded projects will be examined with regard to their level of energy ambition and their potential for reducing greenhouse gases. Gaps in the transfer between research and implementation are also to be identified.

From the point of view of the project partners, the reduction of the performance gap, i.e. the deviation of the energy consumption and GHG emissions measured during operation from the target and planning variables, is central to the achievement of the reduction target, which is why this is the guiding theme of the accompanying research. In order to overcome these challenges, improved quality assurance processes in all phases of construction planning and implementation up to operation are indispensable and therefore a central object of investigation.  In addition, new business models can make a decisive contribution to the achievement of objectives. Selected funding projects will be used to show what these can look like.

The scientific claim of the accompanying research is strengthened by five dissertations, which are thematically related to the accompanying research, which are being prepared at various universities within the framework of the research college EnEff.Gebäude.2050. In addition, the project has already accompanied the ideas competition for the development of concepts for an international energy competition. The work of the accompanying research EnEff.Gebäude.2050 is carried out in coordination with the accompanying research for "Energy-optimised buildings and neighbourhoods" and the project management organisation Jülich (PTJ).

The basis and at the same time task of the accompanying research is the collection and processing of relevant information from the accompanying projects on the above-mentioned topics. The information is collected by means of questionnaires and interviews. Furthermore, the assessments of the project leaders on important topics and thematic gaps of the heat transformation are collected in workshops, where the information from the questionnaires and interviews is partly reflected with the aim of networking the participants.
