Since it was founded in France, EOLIOS has turned computational fluid dynamics into a genuine decision-making tool for the most critical infrastructures. A look back at the journey of a consultancy that became a reference in thermal and airflow simulation, across Europe and the world.
EOLIOS Ingénierie was born of a conviction: numerical simulation can make the most complex thermal and airflow phenomena visible — and controllable. Where physical testing is expensive and fixes a single configuration, CFD opens up the field of scenarios: you compute, you compare, you optimise before you even build. From this founding idea grew a consultancy that places scientific rigour and clarity of reporting at the heart of every project.
EOLIOS came to life in France around a team of engineers convinced that computational fluid dynamics should leave the laboratories to serve real projects. The first studies — HVAC engineering, industrial natural ventilation, wind comfort — established a method: model faithfully, measure to calibrate, report clearly.
To never compromise on precision, EOLIOS invested in a hybrid computing infrastructure — in-house HPC servers, elastic power in the cloud — and structured its expertise around seven areas of expertise. The team grew with PhD engineers in fluid mechanics, one lead per discipline.
EOLIOS collaborated with Ateliers Jean Nouvel and Terrell on the Shaaran resort in AlUla; joined the Impulse Partners ecosystem; was featured in Challenges magazine and present at Data Centre World Paris. A year that anchored EOLIOS's CFD signature among architects, operators and the press.
Present at the 2024 Data Center Show (stand H90), EOLIOS multiplied the thermal digital twins of data centers, from server-room diagnosis to external simulation of the air coolers. CFD established itself as the reference tool for securing cooling and optimising PUE.
EOLIOS has 9 offices — Paris, London, Milan, Munich, Madrid, Warsaw, Casablanca and in the United States — and supports manufacturers, operators, architects and project owners on their most demanding projects, from data center to industry, from commercial buildings to critical infrastructure.
Airflows, heat transfer, pollutant dispersion, thermal stratification: so many phenomena the eye cannot perceive but which decide the comfort, energy and safety of a building. CFD turns them into clear maps and concrete decisions.
This stance — model to decide — guided EOLIOS from its very first projects and still structures each of its studies today, from a one-day consultation to the most complex R&D work.
Initially founded in France, EOLIOS Ingénierie is today a reference consultancy in thermal and airflow simulation, across Europe and internationally. From aeronautics to pharmaceuticals, from sport to energy, our studies cover a broad spectrum of sectors.
Everywhere, the same scientific demand and the same rigour of reporting: it is this consistency that has made EOLIOS a trusted partner of the largest operators and designers.
High-fidelity models, calibrated on real measurement campaigns and led by PhD engineers in fluid mechanics.
Results translated into usable maps, sections and videos: our clients decide quickly, on solid foundations.
We do not sell equipment: our recommendations serve only the performance and safety of the project.
Comfort, energy, safety, air quality: our CFD engineers turn your flow questions into concrete decisions.
