Repair And Modernization Measures Are The Dominant Component Of Construction Investments. More Than 2/3 Of All Housing Construction Investments Relate To Existing Buildings. Even In Non-Residential Construction (Commercial And Public Buildings), The Existing Construction Work Now Exceeds The Volume Of New Construction. However, There Is Insufficient Data Available In Official Statistics On The Scope And Structure Of The Measures In Existing Buildings. Therefore, The Approximate Difference Calculation By The German Institute For Economic Research (Diw Berlin) Has Already Been Supplemented Six Times By An Empirical Survey. This In-Depth Survey Will Now Be Repeated A Seventh Time In Order To Ensure The Calculation Of Consistent And Reliable Time Series. The Aim Of The Research Project Is To Obtain Current, Reliable Data On Existing Measures In Residential And Non-Residential Construction. Using Primary Surveys, The Measures In The Housing And Non-Residential Stock Should Be Examined In A Differentiated Manner According To Full And Partial Renovations, Energy Measures And From A Regional Perspective. In Terms Of Methodology And Content, The Project Should Largely Be Based On The Previous Studies (Existing Investments From 2010, 2014, 2018, 2020, 2022 And 2024).
