Mercialys is looking to reduce its water and energy consumption with a view to limiting the environmental impact of its activities.

Saving energy

To reduce its environmental impact, Mercialys has rolled out a dedicated tool for monitoring consumption levels. Most of the sites are equipped with a centralized building management system for managing the various equipment in its centers. Alongside this, to reduce requirements for artificial lighting, Mercialys encourages natural lighting by setting up light wells when renovating its centers.

These measures are making it possible to optimize the centers’ energy efficiency.

Like-for-like, the energy intensity of Mercialys’ centers was reduced by 4% between 2015 and 2016.


Goal 2020 : Reducing energy intensity by 20% compared with 2015.

Saving water

Mercialys is working to reduce water consumption levels in its centers. Among other developments, this can be seen with the water-efficient equipment deployed, as well as the installation of rainwater recovery tanks to supply the restrooms or garden area watering networks.


Goal 2020 : Reducing water consumption by 15% compared with 2015.

Very selective sorting

Mercialys sorts waste for visitors and retailers in its centers. Bins are made available to visitors in the centers and each retailer has several units for sorting its waste (plastics, cardboard, fermentable waste, etc.).


20% of waste were recovered in 2016.


Goal 2020 : Recovering 55% of waste compared with 2015.
