The leading Swiss firm in technical engineering for sustainable buildings, Amstein + Walthert, who have offices based in Geneva, created their new subsidiary in France at the beginning of March 2014 after several years of operations in the country. “The difference between Lyon and Paris or Annecy is the city’s economic dynamism and its involvement in the cleantech industry in relation to construction and sustainable development, as well as its geographical location and zone of influence. All these advantages were highlighted by Aderly, who were an essential part of our decision-making process leading to the choice of Lyon”, explains Corentin Maucoronel, Managing Director of the company.


In addition to assisting the company with its decision-making,Aderly also supported Amstein + Walthert during the different stages of setting up in Lyon – the search for office premises adapted to their needs, legal advice, recruitment of qualified staff and connections with eco-constriction networks in Lyon.


With premises in the centre of the Part-Dieu district of Lyon, the company offers high quality services in fluid engineering and assistance with sustainable construction management, including: physical and ecological aspects of buildings (environmental certifications HQE, LEED, BREEAM, DGNB), building pathology, vapour diffusion into cavity walls, condensation risks, comfort and quality of air in premises, LCA, energy management (buildings energy audits, energy renovation plans and energy optimisation in industrial processing, dynamic energy simulation, flow dynamics) and regional energy planning.


Amstein + Walthert assist their clients with their construction projects by offering the benefit of their extensive experience, unique know-how and innovative concepts developed through their R&D work with partners from the academic world. Founded in 1927, the engineering team now employs more than 650 people who work with complete independence and neutrality: 100% of the company’s share capital belongs to its managers.
Amstein + Walthert are organising a meeting on the 20th May in the Onlylyon Skyroom in the Oxygène Tower in order to present the company and its new cleantech technology for buildings developed through experience with industrial collaborators and Swiss polytechnics. The event will end with a networking cocktail party. To find out more or to take part, contact Corentin Maucoronel à
