SUSTAINABILITY REPORT 2018 Energy efficiency technologies > Lighting The Ibersol group has identified advantages in swapping conventional lighting for led lighting, benefiting from a return period of 1 to 2 years, due to the sharp reduction in the facilities’ energy consumption. Besides reducing energy consumption, led technology leads to a de- crease in electrical losses in the facilities, a reduction in atmospheric pollutants and, due to its useful lifespan, a decrease in the cost linked to maintaining the installations. We replaced halogen lamps, which generate a lot of heat, and con- sequently a greater need for cooling the spaces, with led lighting solutions. This initiative led to a reduction in energy consumption, and simultaneously, was better suited to the aesthetic requirements of each space. In addition, replacing halogen lamps with led ones enabled mainte- nance costs to be reduced, as these lamps have a lifespan of up to 45,000 hours and an energy saving of up to 85%. > Electronic ballasts We chose to replace the conventional ballasts with electronic ballasts, due to the considerable reduction in energy losses. When fluorescent lamps are linked to electronic ballasts, they produce 20% more and cause the lamps to start up more gently, which increases their useful lifespan, with lower maintenance costs, without the need for starter devices. > Lighting control Control systems are an important component in the Group’s stores, aiming to ensure that the lighting operates when necessary. The light- ing integration and regulation systems fitted in the Group’s facilities enable control to be carried out by time or by occupation (presence detection) and enable switches to be installed in specific compart- ments, so that when they are unoccupied, they can be switched off locally. Switching off the lighting to save energy is one of the most 45
