Natural resources

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.

In 2019

Like-for-like, energy intensity per sq.m was reduced by 9.4% for Mercialys centers versus 2015. 


2020 goal

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 (pressure reducers, waterless urinals, dual flush systems, etc.) deployed, as well as the installation of rainwater recovery tanks to supply the restrooms or garden area watering networks.


In 2019

Water consumption was reduced by 4.3% on average versus 2015.


2020 goal

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.). Furthermore, in 2018, workshops were also held at the Quimper and Toulouse sites to understand retailers’ expectations in terms of sorting waste and to improve selective sorting rate.




In 2019

59% of waste was recovered.


2020 goal

Recovering 55% of waste.


Protecting biodiversity

Mercialys aims to help protect “urban” biodiversity: for instance, it maintains its green spaces with a “zero pesticide” approach and is committed to supporting the fight against species that harm biodiversity. In 2017, building on its progress, beehives were set up on the roof of the Galerie Espaces Fenouillet center in Toulouse. In 2018, when the honey was collected, visitors were invited to discover how the hives work and sample the honey.




2020 goal

Engage in protecting ordinary biodiversity.
