We act with an awareness of the environment and respect for its resources – whether in terms of investments in real estate, property management or the associated services and uses.
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.
When carrying out modernisations or constructing new buildings, we promote the circular economy by reusing materials that are thought to be at the end of their life cycle. In doing so, we reduce waste and the cost of materials. One example of this is our property on Müllerstrasse in Zurich, where we are deconstructing the old aluminium facade, recycling or cleaning it and reinstalling parts of it. As a partner of Madaster Switzerland and CE2 Circular Economy Entrepreneurs, we are dedicated to the circular economy in the real estate and construction industry. In 2021, construction of Swiss Prime Site Immobilien’s pilot project for circular construction began.
When it comes to our new buildings, in the medium term we aim for emission-free construction, and in the long term we aim to use them for energy production. We construct new buildings in accordance with green building standards such as LEED, Minergie®, the German Sustainable Building Council (DGNB) or the Swiss Sustainable Building Standard (SNBS). Properties already awarded Minergie®, LEED or DGNB certifications include EspacePost in Berne, SkyKey, Media Park and Prime Tower and Platform in Zurich, Stücki Park in Basel and the Opus 1 and 2 building complex in Zug. In 2019, the Schönburg residential estate in Berne was also converted according to SNBS criteria. For our largest development project in Geneva, ALTO Pont-Rouge, we likewise adhered to SNBS requirements and are aiming to receive certification after completion in 2023. In the portfolio, 16 buildings are currently certified according to BREEAM In-Use (building, operation). The aim is to extend this certification to a around 20 more existing properties in 2022.
