Losinger Marazzi, Bouygues Construction’s Swiss subsidiary, has won four projects in Switzerland worth a total of 401 million Swiss francs (€410 million). From a positive energy neighbourhood to multi-use solar energy spaces, these buildings will play a vital part in the daily lives of residents and respond to the challenges of energy transition and the low-carbon society.

AARERAIN: the first positive energy neighbourhood in Switzerland

In Worblaufen, north of Bern, the Aarerain project can claim to be Switzerland’s first positive energy neighbourhood, built for the Coop Pension Fund (CPV/CAP). This new residential neighbourhood will produce more energy than it consumes, according to the weighted criteria employed by the Positive Energy Neighbourhood standard. Systematic installation of photovoltaic panels on the roofs and facades of the six- to eight-storey buildings will make this possible. Geothermal probes will be responsible for heat production. As well as apartments, the development will include a day-care centre and workshops at ground floor level, the presence of which will help bring the neighbourhood square to life.

QUARZ’UP: a range of uses under one roof

One distinctive aspect of the Quarz’Up project, which is located in the town of Vernier, near Geneva, is the variety of uses served by its four buildings, which will accommodate several types of companies, including start-ups, local craft businesses and international high-tech players. The site enjoys sustainable energy supply, mainly thanks to centralised heat production provided by energy company SIG (Services Industriels de Genève) and photovoltaic roof panels. Constructed for Arab Bank Switzerland, Quarz’Up aims to strengthen links between economic activities and the population, thanks to the inclusion of a farm and urban greenhouses, encouraging short supply circuits. Quarz’Up will seek both Minergie® and WELL Community certifications, attesting to its commitment to the environment and to the comfort and quality of life of its occupants.

SEETALPLATZ CANTONAL ADMINISTRATIVE CENTRE : a mixed-use project that will serve the whole community

This new construction will allow around 1,450 employees of the Canton of Lucerne to work under one roof. The building has been designed for a variety of uses alongside standard office functions. It will provide reception areas for the public, a police station, restaurants and shops on the ground floor, as well as apartments and a day-care centre on the upper floors. A mixed concrete-wood structure, the project consists of a six-storey base and a tower. At the centre of the complex, a building dedicated to receiving the public will be entirely constructed in timber. Photovoltaic modules will be installed on the roofs for the production of electricity. All heat and cold will be supplied by a connection to the Seetalplatz urban heat network. The offices and restaurants will enjoy natural light thanks to the roof terrace of the atrium, and to the three internal courtyards that provide a pleasant environment. The building is being constructed for the Canton of Lucerne.

AUX ACACIAS : an integrated project in the heart of Geneva

Aux Acacias, a project located in the centre of Geneva, was designed in a competition lasting almost a year. It was selected for its urban and architectural qualities, its energy performance and its limited environmental impact, as well as its economic feasibility. The Aux Acacias complex will surround a tree-lined square with several points of access, creating an open ensemble. Built for the Acacias-Lièvre B SA property company, the project incorporates 4,000 m² of retail space intended to revitalise the neighbourhood, along with a range of while offering a variety of accommodation options over a total surface area of 36,000 m². Aux Acacias will benefit from CO2-neutral heat production.
