Reducing energy consumption through energy efficiency measures is today an important action to reduce costs in companies and boost their competitiveness.

Relighting in 3 stores

Leroy Merlin was supported by Helexia in the management and implementation of an efficient lighting project in three of its stores: Coimbra, Maia and Matosinhos. The execution of this relighting project corresponded to a 36% decrease in consumption and a significant reduction in maintenance costs for lighting equipment.

In this way, Leroy Merlin will avoid around 990 tons of CO2 each year and enjoy annual savings of over 95,000 euros.
