How can the management of buildings, transport, energy, water and waste be revisited so as to bring about more effective and cost-efficient management? Such is one of the challenges of the city of the future. Martial Chevreuil, the group’s Innovation and Development Director, was interviewed by Catherine Cappellaere for the magazine SQY Entreprises, the business journal published by the Saint-Quentin-en-Yvelines joint authority.

A challenge at the heart of engineering solutions deployed by the international group Egis. The group develops a wide range of tools to design the city of the future, its mobility, its infrastructure and its networks. “We deploy a systemic approach in our projects’ design and construction phase,” explains.
Martial Chevreuil, Innovation and Development Director. “We use simulation tools for cities, buildings and travel. We also simulate energy consumption in order to then consider the solutions that we can contribute to make the city inclusive, sustainable and emit the least greenhouse gas possible whilst not hampering its economic development.” In designing the smart city, Egis also advocates an approach where the sectors and activities within the city work seamlessly with each other. “Making the people in charge of transport and those in charge of highways work together, for example, helps to capitalise on all the potential out there and cross-reference their issues to achieve better efficiency.” Egis has designed a digital model to draw the infrastructure of a building using pooled resources. “The various engineers from all the speciality areas of building engineering contribute to the model. We can then immediately see the interactions at work, for example between all the different cabling. This can also help us to simulate the operation of the building in terms of heat performance or in its energy consumption. Our ambition is to deliver a similar model on the scale of a town by drawing on contributions from all of its stakeholders and operators.”
ROSAU is the name of a new tool developed by Egis to make the city resilient. “The aim is to anticipate damage in the event of exceptional climate events. We produce a cartography of the city’s water network and we plan for a flood disaster scenario. This helps us to identify the weak points of the network and take the necessary action in advance.” Other areas of research include the shared management of energy within a neighbourhood, and designing buildings which can be reversible in their use. Transport infrastructure is also part of the research scope, with the possibility of earmarking road lanes for specific purposes at specific periods. The city of Lyon for example is currently testing the non-exclusivity of a bus lane at certain times of the day to ease traffic congestion. “We are currently discussing these solutions with SQY, in particular to improve visiting conditions in the area for the 2024 Olympics and Paralympics.”
