Bouygues Construction Wins 4 Major Projects in Switzerland

Losinger Marazzi, Bouygues Construction’s Swiss subsidiary, has won four projects in Switzerland worth a total of 401-million Swiss francs. From a positive-energy neighborhood, 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: first positive-energy neighborhood in Switzerland
In Worblaufen, north of Bern, the Aarerain project can claim to be Switzerland’s first positive-energy neighborhood, built for the Coop Pension Fund. This new residential neighborhood 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 façades of the 6-8-story buildings will make this possible. Geothermal probes will be responsible for heat production. As well as apartments, the development will include a daycare center and workshops at ground-floor level, the presence of which will help bring the neighborhood 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 a sustainable-energy supply, mainly thanks to centralized heat production 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 to serve 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 daycare center on the upper floors. A mixed concrete-wood structure, the project consists of a six-story base and a tower. At the center 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 center 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 square meters of retail space intended to revitalize the neighborhood, along with a variety of accommodation options over a total surface area of 36,000 square meters. Aux Acacias will benefit from CO2-neutral heat production.
