Ausgeschöpftes und vorhandenes Sanierungspotential auf Basis von Energieaus-weisdaten

It is suspected that the renovation rate of buildings is higher than commonly assumed due to the number of unreported renovations. Consequently, the actual savings potential achievable through renovations is lower than previously estimated. To verify this hypothesis, energy performance certificates from the ZEUS database for existing buildings in the state of Salzburg are being analyzed. This includes identifying undocumented renovation measures and quantifying the effective savings potential at the building level.

The assumption is confirmed that the building stock exhibits significantly better energy efficiency than would be expected for the respective construction periods and building types. Approximately half of the achievable savings potential through renovations has already been realized.
