Improving energy efficiency

By improving the energy efficiency of stores, the Group reduces their electricity consumption and its indirect impact on greenhouse gas emissions. It continues working towards its target to reduce its electricity consumption per square metre of retail space by 20% between 2012 and 2020.

Reducing energy consumption is addressed through a continuous improvement process, which is based on carrying out energy audits for sites, monitoring consumption, and implementing an energy renovation programme. In France, more than 800 Géant and Monoprix stores and Casino supermarkets are covered by Energy Performance Contracts (EPCs).

Commercial refrigeration systems are one of the biggest sources of energy consumption within the group, which is well on the way to meeting its commitment to installing doors on 75% of its refrigeration and freezer units by 2020. 100% of Géant hypermarkets, 80% of Casino Supermarkets and 44% of Monoprix stores were equipped in 2016, along with 100% of new Franprix and Casino Shop stores.

In Brazil, the 140 GPA hypermarkets and 182 supermarkets underwent energy renovation work in 2015 and 2016 to switch to LED lighting and improve air conditioning and commercial refrigeration systems. In Colombia, Exito develops natural lighting, fits stores with LED tube lights and is standardizing the installation of smart meters.

Renewable energy generation continues to be developed at Group sites with the installation of solar power generation units on roofs and solar canopies at hypermarket car parks. In Colombia, two photovoltaic systems were rolled out in 2016; the one in Barranquilla is the largest in the country. 50 installations were in operation, representing a solar panel surface of 5.50.000 sq.m.

Energy efficiency is one of the criteria applied in the environmental certification of buildings. In France, 30% of shopping centres are certified Outstanding under BREEAM In-Use standard. In Columbia, Grupo Exito was awarded LEED Silver certification on two occasions for the Exito store in Cundinamarca and LEED Gold for the Viva de Riohacha shopping centre. Three Pao de Azucar stores were also LEED-certified.
