Through the consistent reduction of our CO2 emissions, we are doing our bit to achieve the two-degree target set by the Paris Agreement and the Swiss Federal Council’s further goal of becoming climate neutral by 2050. When it comes to existing properties, our EC/BO online system (energy controlling and business optimisation) continually records the energy consumption of 144 properties (corresponds to 93% of the total area of the property portfolio), allowing us to carry out ongoing optimisation of the heating, cooling, ventilation and lighting systems. This enables us to significantly reduce our energy consumption and our CO2 emissions. In order to increase self-production of renewable electricity in the future, the entire property portfolio was reviewed in 2019 for its suitability for the installation of photovoltaic systems and 18 properties were identified. In 2021 four photovoltaic systems with a total output of 630 kWp and a yield of around 640 000 kWh were put into operation. At the end of the year, there were 16 PV systems. In 2022, at least two further systems will be put into operation.
In 2021, two existing properties were connected to the district heating network and three new builds with renewable heat energy were put into operation. In a range of properties, Swiss Prime Site Immobilien also benefited from the improved environmental quality of district heating.
