Research interests

My work focuses on researching decision-making dynamics in the energy system. Coordinated and targeted investment decisions by private building owners are particularly necessary to advance the energy transition. I use agent-based modelling and network analysis methods to investigate factors influencing these decisions in the context of changes in infrastructure.
Methods:
  • Agent-based simulation
  • network analysis

Heat Trans­ition of the Urban Build­ing Stock by In­ter­act­ive De­cision Space Ana­lysis

The project WAERMER shall apply a methodical integration of energy system optimisation on an urban level and agent-based modelling of individual investment behaviour including preferences and scope of action. It shall help identify the requirements for a successful transition of heat provision in the urban building stock towards CO2-neutrality. Building owners are surveyed about relevant factors of their investment decision making. In an iterative process, measures to incentivise individual investments can be developed and simulated as well as required adaptations to the technical energy system identified. The agent-based modelling explicitly considers the influence of energy consultants and craftspeople concerning their changing knowledge and recommendations.
