- 1)Partially limited comparability due to delayed availability of actual data.
- 2)All available meter readings from tenants were taken into account. For economic units without consumption data, the water consumption was extrapolated to the total area of the portfolio on the basis of the average consumption per square meter.
- 3)Water consumption of the office locations included in the scope in the reporting period; missing values were estimated on the basis of the area and average consumption of comparable locations. Water consumption at office locations in Austria based on projections from previous years.
