By utilizing 'Simulia', one of Dassault Systèmes' 3DEXPERIENCE platform solutions, the accommodations for the Paris Olympics were maintained at a comfortable temperature on the 26th.

Dassault Systèmes and the Société de Livraison des Ouvrages Olympiques, the French public agency responsible for long-term infrastructure and facilities, announced on the 22nd that they have joined hands to optimize the comfort of accommodation for 14,000 people in the Paris area.

Dassault Systèmes used SIMULIA to analyze accommodations and provide guidance on improving indoor comfort, taking into account France's record-breaking summer temperatures in recent years, to SOLIDEO, the public body in charge of building Olympic infrastructure.

Simulia provides multiphysics simulation capabilities for evaluating structural, fluid, electromagnetic, and motion performance in product design. Dassault Systèmes said it “enables designers to evaluate and improve designs to meet functional design requirements while reducing costs.”

Dassault Systèmes used Simulia to create a 3D model of the upper floors of one of the buildings, based on data provided by Solideo and construction partners. We simulated parameters such as ecological systems for insulation, ventilation, solar shading, and underfloor cooling to calculate indoor temperatures throughout the day.

The effectiveness of solar shading and the innovative cooling floor were demonstrated according to location and time of day. Solideo verified how each parameter in the building worked in the simulation and whether the building design as planned could optimize indoor comfort levels at any time without additional structural solutions.

“Building environmentally friendly accommodation that protects the health of athletes staying inside the building, even during extended heat waves, is a top priority for us,” said Antoine du Souich, Strategy and Innovation Director at Solideo. “Dassault Systèmes’ simulations have confirmed that we can deliver on these capabilities, both this year and in the future as the building is repurposed for new occupants.”

“Dassault Systèmes’ simulations have provided Solideo with key insights to optimize comfort inside buildings even as outside temperatures soar,” said Jacques Beltran, Vice President, Cities and Public Services, Dassault Systèmes. “With Simulia, we can simulate every scenario—from heat inside buildings to airflow inside hospitals, offices and concert halls to the outdoor heat island effect in urban areas—to understand things that other methods cannot, and contribute to a safer, healthier quality of life for our citizens.”
