Residential renovation in Slovenia: comparison of survey and registry data

Data on residential renovations are crucial for assessing their energy efficiency and living conditions of residents. Based on the real estate register data in Slovenia, we have information about the year of construction of buildings, as well as the year of renovation of roofs, facades, windows, and installations. However, the data for the period after 2007, when the last real estate census was conducted, is incomplete. Moreover, official surveys also have very limited data on this topic. To get more detailed insights into the renovation procedures of Slovenian households, we conducted our own survey on a web panel, which provided insights into renovation characteristics not captured by existing data sources. This contribution compares survey data on renovations with registry data and attempts to evaluate the quality of survey data.
