Saving resources

Our energy management system

The management of water and energy consumption is a fundamental aspect of our environmental policy. An energy management system has been introduced in our entire fleet of buildings in France. This commitment resulted in our obtaining ISO 50 001 certification, renewed in 2017.

Target: reduce energy needs

Our new energy management system aims to reduce by 4% the energy consumed by our buildings over three years. Since 2018, this approach has also included fuel consumption. For the building fleet outside France, not subject to the ISO 50001 approach, we have decided to systematically conduct energy audits in order to achieve additional energy savings.

Investing in performance

Starting with the design of our buildings, we pay particular attention to the energy performance of the materials and equipment used. Our cooling systems are regularly checked and improved to limit the consumption of water in air cooling towers.
This concerted policy also applies to the management of our fleet of machinery. Almost our entire fleet of prime movers is now compliant with the Euro 6 standard and the consumption of each vehicle is closely tracked. In order to reduce the amount of fuel consumed, all our drivers are trained in eco-driving.
