To analyze the impact of energy efficiency ex ante usually technology-based models are applied. However, because of limited knowledge about long-term technological progress, the applicability of this approach is restricted for long modelling horizons (Grupp, 1997). The objective of this study is to develop a concept that considers technology myopia in long-term energy demand modelling in the residential sector. To emphasize the added value of this study the concept will be applied to the German residential sector in terms of explorative scenarios up to 2050 focusing on electricity.enBottom-up analysisRegression analysisPatent analysisEnergy efficiencyResidential sector303600presentation
