The renovation of the Geoffroy Guichard Stadium in Saint Etienne touches one of the temples of football in France. The successive construction of tribunes and roof frame works mark a milestone with the passage of draft standards for the organization of UEFA European Cup 2016. The increase of space, comfort of the spectators, the continued operation during construction, the occurrence of seismicity in Saint Etienne are parameters that shape this project, whose ambition is to give a unity to the personality of the stadium.

In April 2011 a comparative survey investigation was carried out using CFD in order to improve airflow comfort in the tribunes of Geoffroy Guichard’s sports stadium in St Etienne.

Airflow comfort analysis focuses on the comfort levels in the tribunes. An analysis of the sports field was also undertaken.
