Abstract
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 Germany’s 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. The results show that efficiency measures in buildings have a significant positive effect on macroeconomic key figures. The magnitude of the calculated impact depends on chosen base year data and varies for value added and employment. As a conclusion, the macroeconomic impact constitutes a co-benefit supporting the economic attractiveness of energy efficiency. However, studies based on a single base year dataset like many computable general equilibrium models may need to reflect the errors caused by that choice.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
