Scenarios have evolved as an indispensable tool for future planning in politics, business, administration, and beyond. Between intuition-based scenario methods and mathematical modeling, the field of semi-formalized scenario methods has been established. These methods are particularly suitable for scenario topics for which only qualitative insights into the systemic interrelationships exist, but which are also too complex for mental analysis.
At the CIB-Lab we focus on the Cross-Impact Balance Analysis, which is especially designed for this type of scenarios. The CIB was developed at ZIRIUS and is now used worldwide for an algorithm-based development of qualitative and semi-quantitative scenarios. The method is thematically generic. Typical fields of application are energy, climate and sustainability research.
CIB is based on the qualitative and/or semi-quantitative elicitation of the interdependencies of a complex system using expert or stakeholder assessments and/or literature analysis. The interdependencies thus compiled define a qualitative impact network that can be evaluated according to formal consistency criteria (the CIB consistency principle), leading to "consistent scenarios" of system behavior. These can be used, for example, for planning, strategy development or intervention analysis.
The aim of the CIB-Lab is to further develop the method and enhance its potential and applicability to new fields. At the CIB-Lab, we:
- implement CIB application projects
- deal with methodological questions concerning CIB analysis, including the development and testing of method extensions
- maintain and further develop the CIB software ScenarioWizard
- maintain the method homepage www.cross-impact.de, which provides aforementioned software, method information and a bibliography
- collect and methodologically analyse published CIB applications to foster learning effects and practical recommendations for the method application
- support the international network of research institutions that apply or methodically research CIB
- advise users, supervise guest researchers, give lectures and conduct training measures.
The CIB-Lab cooperates closely with the research area "Method Development" at ZIRIUS.
Application and methodological research projects
The project deals with the influences on water demand and supply in the Peruvian Andes. At the CIB-Lab, scenarios are being developed in cooperation with local actors to provide information on the supply risks for the economic sectors and social groups concerned and to provide orientation for the hydrological model calculations of the project.

The BMBF-funded project "ENavi " investigated the interactions between technology development, forms of organization, regulation and behavior. It thus expands the focus and views energy system transformation as a profound and systemic process of technical and social change. At the CIB-Lab, leitmotifs for energy system transformation are analyzed and compatible "technospheres" constructed, and the effects of social change on electrical load profiles are researched.

As part of the AutGrid project, Fraunhofer ISE and ZIRIUS analyzed autarky developments in the energy regions. To this end, the social science part of the project used expert interviews and workshops to investigate which factors are driving energy self-sufficiency efforts and how they interact. On this basis, consistent context scenarios were calculated, which show where the regions are located, to what extent they are self-sufficient and how this could develop until 2050. For the identified scenarios, an optimization model with high temporal and spatial resolution was used to show the effects on the German energy system. The study focused on a comparison of the scenarios with regard to system costs, required network expansion, network capacity utilization and the technology portfolio.

Various activities for the use of renewable energies, energy saving and emission reduction of municipalities, regions, but also federal states can be bundled under the keyword "energy self-sufficiency". Against this background, an interdisciplinary research team of engineers and natural scientists as well as economists and social scientists prepared, carried out and interpreted simulations that determine the infrastructure required for a regional optimum. The task of the CIB-Lab was to create context scenarios that analyzed the framework conditions of self-sufficiency efforts and served as a starting point for the model simulations.

The aim of the project was to investigate perception and evaluation patterns of (qualitative) energy scenarios by potential scenario users in politics, economy and society. The scenario community often uses the concept of 'plausibility' as a means to limit the space of scenario development and evaluation. Although it presents a central term in scenario research, it remains conceptually or empirically underexplored. An interdisciplinary theory exploration of the concept was conducted. This informed a semi-experimental study that analyzed how plausibility assessments are formed for different scenario formats. The Intuitive Logics (IL) method and the Cross-Impact Balance Analysis (CIB) were used as scenario formats.

In the project City with Energy Efficiency - SEE Stuttgart, the CIB was used to develop the widest possible range of consistent scenarios for a climate-neutral city of Stuttgart in 2050. These scenarios served as a basis for the City of Stuttgart to formulate a roadmap. The ZIRIUS did not play a leading role in the scenario development, but supported the project partners methodically, e.g. by conducting a CIB training and also in the evaluation using the CIB software SzenarioWizard. ZIRIUS was also involved in the scenario development, e.g. in the creation of the cross-impact matrix and in the interpretation of the results.

The LiWa project was funded by the Federal Ministry of Education and Research (BMBF) under the programme "Research for the sustainable development of tomorrow's megacities - energy and climate efficient structures in urban growth centres". The objective of the LiWa project was to develop concepts and procedures for the sustainable planning and management of water supply and sanitation in Lima, the capital of Peru. Among other things, scenarios for the future water supply were created on the basis of hydrological simulations together with German and Peruvian partners and with the help of the CIB method. Subsequently, effective, socially acceptable measures were developed in participatory forums, which particularly take into account the effects of climate change and the promotion of energy-efficient structures.

This project dealt with the uncertainty and interdependence of framework assumptions in environmental model calculations. Model framework assumptions are often used in modeling practice without a systematic analysis of their mutual influence relationships and thus affect the validity of the model results. In this project, commissioned by the German Federal Environment Agency, it was demonstrated how the CIB procedure can be used to develop systematically constructed and internally consistent framework data sets for environmental models.

In this project, funded by the Baden-Württemberg government, a conceptual alternative to the conventional three-pillar model of sustainability was developed. Part of this was a CIB analysis that examined the systemic implications of the interactions between the different fields of action of sustainability. For this purpose, the cross-impacts between 19 sustainability criteria were collected in an expert survey. The resulting impact network was evaluated using the CIB method. A ranking of the systemic impact for the criteria was established and the key factors dominating the systemic impact were identified.

In this case study, the possibilities of integrating the effects of innovation processes into energy-economic modeling were examined. The contribution of the CIB method consisted in an analysis of the political and economic environment structures that could favor or inhibit innovation processes. For this purpose, four innovation and four energy experts developed a qualitative model of the interdependencies between political measures, entrepreneurial structures and technological developments in a series of workshops. The model was evaluated using the CIB method, transferred to innovation scenarios. On this base, the systemic effectiveness of different policy patterns was assessed.
