1)Calculation logic according to ESRS E1–5.
2)Composed of electricity consumption in the communal areas of the portfolio and total heat consumption in the portfolio (according to energy performance certificates, calculated for residential and communal areas).
3)Calculation logic according to GRI 302–3.
4)When calculating the thermal energy used, the rental areas were extrapolated to the total building area in accordance with GEG 2020 Section 82 (2) using a 20% surcharge for the communal areas. The denominator of this key figure remains the rental space excluding communal areas. Renewable energy from electricity in each case location-based.
5)Calculation of renewable energy share based on location-based approach. Determination for Germany based on data from the German Association of Energy and Water Industries (BDEW), for Austria based on data from the Federal Ministry for Climate Protection (BMK), and for Sweden based on data from Swedenenergy (Energiföretagen Sverige).
6)For Germany, all volumes traded via Vonovia Energy Service GmbH (VESG) are 100% green electricity with proof of origin, deleted via the Federal Environment Agency's register of guarantees of origin (market-based approach). Remaining electricity volume purchased for Germany calculated according to data from the German Association of Energy and Water Industries (BDEW) (location-based approach). Calculation for Austria based on the Austrian electricity mix according to the E-Control statistics brochure 2025 (location-based approach). Calculation for Sweden based on proof of origin verified as 100% nuclear-generated energy (market-based approach).
7)Mobile combustion only (vehicle fleet) – diesel, gasoline, gas.

1)Photovoltaic systems owned by Vonovia as of December 31, electricity generation only.
2)The proportional increase in the number of plants and installed capacity can deviate from the energy generated, as the number of plants also includes plants that have already been built and will not be connected to the grid until the following year.
3)Theoretical annual emissions avoidance from energy generated by means of photovoltaic systems and fed into the general power grid. Calculated with emission factor for Electricity displacement mix PV, source: Federal Environment Agency (for Germany). Comparability with previous years is limited due to differences in emission factors per kWh of electricity over time possible to a limited extent.
