Modelling of individual decision processes and the influence of intermediates in regard to the diffusion of energy efficiency methods and renewable energies in the building sector

Interdisciplinary joint project in the context of the 6th energy research program of the Federal Government

The aim of the project is to understand how individual decision processes and relevant agent relationships in an energy system model for the building sectors have to be pictured. Taking aspects of technology acceptance into account, the predictive efficiency of scenarios for diffusion of energy efficiency measures and renewable heat supply systems on existing and new building stocks in Germany could be increased.

As a basis for the energy system modelling the bottom-up simulation model INVERT/EE-Lab with the agent-based investment decision module INVERT-Agents is used. In order to extend and improve the already existing module significantly, the planned project targets a strong interdisciplinary approach by integrating socio-psychological aspects into the engineering-econometric modelling. Three socio-psychological studies for three groups of players in view of Eneff/EE-methods are planned. Results of the studies are supposed to be used for the extension of INVERT-Agents:

The following stakeholder groups are addressed:
Group 1: Owner of residential buildings (i.e. self-interested owner, community associations, private landlords, professional landlords/ community associations)
Group 2: Owner of non-residential buildings and decision maker in organizations with non-residential buildings respectively (i.e. people who have essential influence on the implementation of Eneff/EE-methods in their company/authority)
Group 3: Intermediates (People who have influence on respective decisions and decision options of (potential) investors, i.e. craftsmen, energy adviser etc.)

The results of the two studies in regard to (potential) investors serve as a basis for identifying subgroups with different decision logics (different motives and barriers, differently structured decision processes, information behaviour, knowledge of and attitude towards assistance measures) within both groups. The study with intermediates is supposed to give some indication of the dependencies of their consulting behaviour and their portfolio of products concerning Eneff/EE-methods in the face of the investors. Subsequently, the multidimensional modelling is expected to picture diffusion dynamics in a better way.
