Energy efficiency measures in buildings are essential for climate protection, but are not always recognized by the investor in common profitability calculations. To provide a quantitative scientific base for policymakers, the aim is to identify and quantify the impact of these measures on Germanyâs economy with a static open input-output model. Moreover, this investigation analyses how much the chosen base year affects the calculated macroeconomic impact, to obtain a clearer view of involved dynamics. The energy efficiency measures in buildings and their impact on energy demand and investments were simulated in the bottom-up building model INVERT/EE-Lab up to 2020. The methodological addition of this research is to identify and map the resulting impulses to the according macroeconomic sectors. Based on this stimulus a static input-output analysis is conducted using a range of base years.
