Integration into direct real estate investments
PUBLICA holds a high-quality portfolio of mostly recently built Swiss real estate. Three quarters of all properties were completed after 2000. PUBLICA also adopts a responsible approach to its direct real estate investments, with a view to improving the risk/return profile of the properties and ensuring that they are as economically efficient as possible. PUBLICA views the real estate asset class from a future-oriented and holistic perspective, as part of risk management that incorporates economic, environmental and social factors. The focus is on the economic and environmental sustainability of projects and existing real estate investments. For example, PUBLICA has defined an ambitious path to reduce CO2 emissions by replacing heating systems that use fossil fuels such as oil with alternatives such as district heating or heat pumps. Where economically viable and technically feasible, PUBLICA implements further measures such as insulating the building shell or optimising operation. PUBLICA also promotes energy efficiency and renewable energies such as photovoltaic, the planting of native flora, and raising tenants’ awareness of natural resource conservation.
Residential development on Neunbrunnenstrasse in Zurich
In 2018, PUBLICA installed a photovoltaic system on the flat roofs of a residential development on Neunbrunnenstrasse in Zurich. The installation came on stream in early 2019 and supplies power to 113 apartments.
A photovoltaic system uses solar cells to convert sunlight directly into electrical energy. Solar thermal collectors, by contrast, are normally used to heat water.
The self-produced electricity is intended to meet part of the energy requirements of the rented apartments and communal areas. The city of Zurich electricity company ewz installed the equipment necessary to individually measure the electricity consumed.
The advantages of a photovoltaic system include:
- ability to generate own electricity from a renewable energy source
- lower electricity consumption from the grid
- a degree of independence from the energy supplier
- partial protection against rising electricity prices over the long term
190'000 kWh/year / 198 kW
The system produces around 190,000 kWh of solar power annually: enough to meet the electricity needs of more than 55 households and allow an electric car to travel round the world 24 times a year, covering almost a million kilometres.
