An exemplary stadium from an environmental viewpoint.
Technical performance and sustainability
This project embodies the perfect alliance between technical performance and sustainability through its key design choices:
- A structure made up of a mix of wood and steel.
- Heating and cooling generation using geothermal power, and use of natural ventilation.
- Harvesting of rainwater to water the pitch and supply water to the toilets.
- Photovoltaic power generation to make the stadium energy positive.
Collaboration with the experts from Elioth
Our teams at Elioth (Egis group) carried out specific studies on the structure and roof.
The reinforced concrete structure was analysed from several perspectives, such as the risk of earthquakes or vibrational comfort. As for the roof structure, its wood-steel makeup called for very specific studies. At Egis, we studied the modelling of the structure, the mixed-material roof structure and the elastomer bearings.
In wishing to make the stadium a lively destination both inside and outside it, the architects wished to have a transparent envelope. Our experts thus selected a membrane made from polyester fibre coated in PVC, which maintains the transparency of the building while protecting spectators from the sun.
They also contributed their know-how to maximise the environmental quality of the project. A life cycle analysis (LCA) was conducted to limit the environmental impact. By implementing a number of actions, including an 8,500 sqm solar power plant, the Allianz Riviera became the first energy-positive Euro 2016 stadium and one of the first eco-stadiums in the world.
