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

08/2022 - 07/2025

Dr. Krebs, Friedrich; Dr. Holzhauer, Sascha; Digel, Ivan; Kaiser, Alwina

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.
