1)From 2022 incl. Deutsche Wohnen (excl. Care segment and SYNVIA).
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)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. However, the denominator of this key figure remains the rental space excluding communal areas. Renewable energy electricity in each case location-based.
4)Renewable energy district heating Germany and Sweden based on data from the respective district heating suppliers (market-based approach), for Austria location-based approach based on data from the Federal Ministry for Climate Protection (BMK).
5)Calculation based on the share of renewable energy in the Swedish electricity mix according to the Swedish Energy Agency, in the Austrian electricity mix according to the E-Control 2021 elec- tricity labeling report (location-based approach in each case). For the German region, all quantities traded via VESG using the 100% green electricity guarantee of origin, deleted via the Federal Environment Agency’s register of guarantees of origin.

1)Photovoltaic systems owned by Vonovia as of December 31; electricity generation only. From 2022 incl. Deutsche Wohnen (excl. Care segment and SYNVIA).
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.
