Ground-breaking ceremony for Bern’s first PlusEnergy neighbourhood
Following an extensive development phase, today's ground-breaking ceremony symbolically marked the start of construction for the high-quality and sustainable Aarerain residential estate in Ittigen-Worblaufen. Handover to the investor is expected to take place at the end of 2026.
Today’s ground-breaking ceremony symbolically marked the start of the PlusEnergy Aarerain neighbourhood in Worblaufen. Following an extensive development phase, preparations for the construction site began in September 2023.
The new development will offer 189 flats for up to 400 residents. In addition to the flats, a daycare centre and studio spaces are also planned on the ground floors, which will enliven the neighbourhood square. The project’s slope path will provide barrier-free access to the Aare area and the municipality of Ittigen’s new leisure and water sports centre. “Good things come to those who wait,” is a well-known saying,” says a delighted Marco Rupp, President of the municipality. “The Aarerain project completes the reorganisation of the Aare area in Worblaufen and fits in perfectly with our sustainable basic ideas of urban development.”
PlusEnergy neighbourhood produces energy surplus
Over the course of the year, the new housing estate will produce more energy than it consumes in accordance with the PlusEnergy neighbourhood energy standard based on weighted criteria. This will be achieved through the consistent use of photovoltaics on the roofs and façades of the six to eight-storey buildings. The PV panels on the façades will be realised in a green-blue colour and reflect the play of colours of the Aare and the surrounding area. Heat is generated by means of geothermal probes; the geothermal probes are regenerated in summer by cooling the flats via the underfloor heating.
The “PlusEnergy neighbourhood” energy standard launched by the Swiss capital region promotes sustainable development in the building sector with a simple and clear definition, thereby contributing to the implementation of the Swiss government’s Energy Strategy 2050. The cantons and municipalities are working together with renowned infrastructure companies and investors. Cantonal Councillor Christoph Ammann adds: “PlusEnergy neighbourhoods enable sustainable development – without compromising on living comfort. I am delighted when such flagship projects shine beyond the capital region.”
Close to nature and sustainable
However, the development will not only score points in terms of its positive energy balance. The sustainable project is characterised by attractive flat layouts, a natural living environment with a view of the Aare and the greatest possible preservation of the green spaces on the banks of the Aare. Keeping the green spaces free is made possible by the compact construction of the site in the eastern part of the plot. Thanks to this skilful urban planning in the sense of economical use of the land, a good half of the plot remains undeveloped and natural. The car-free neighbourhood square between the buildings offers a high quality of stay and counteracts overheating in summer with its differentiated paving and greenery.
The symbolic ground-breaking ceremony on 9 April 2024 marked the official start of the development of the Aarerain PlusEnergy district in Worblaufen, a project by Losinger Marazzi in collaboration with the CPV/CAP Coop pension fund and the municipality of Ittigen. The architecture was designed by Fischer Architekten AG. This ultra-modern residential development is scheduled for completion at the end of 2026 and will not only offer 189 flats, but also communal facilities such as a daycare centre and studios to enliven the neighbourhood.
