Abstract for: Coupling System Dynamics and Life-Cycle Assessment to Assess Environmental Impacts of Residential Heating Electrification

Decarbonizing residential heating requires ensuring thermal comfort while reducing emissions. Existing studies focus either on technology diffusion or environmental impacts, but rarely integrate both, limiting system-level understanding of heating transitions. In our study, we couple system dynamics and life-cycle assessment to evaluate residential heating electrification, linking heat pump adoption, useful heat demand, and environmental impacts. A year-resolved framework enables system-level analysis under evolving background scenarios (electricity grid). The approach enables system-level assessment of heating transitions by capturing interactions between technology adoption, behavior, and environmental impacts over time. In future research, this could support more robust evaluation of policy interventions and improve understanding of drivers shaping decarbonization pathways.
