Zalando, Europe's largest online dealer for shoes and clothing, inaugurated operation for its largest logistics centre until now in December 2012 in Erfurt, Germany. Several thousands of pairs of shoes and fashion articles are to be found in the walkable high racking systems spread over an area of 120,000 m². Thus Zalando Picktower is at the same time Europe's largest clothes cupboard.
The main criterion of the lighting system for Zalando was economy. Low procurement costs as well as low operating and power overheads were a main point of focus for the decision-makers. Preview analyses had also shown that employees were to be found in only around 16% of all of the aisles, representing enormous savings potential for the other 84%.
A further point: Because installation with projects of this size quickly become a cost factor, rapid and simple mounting was also important for Zalando.
Today over 63 km of trunking make up the lighting of the logistics centre. Hexal®-a luminaires (1x 35/49/80 W with DALI Multiwatt ECG) from the OSRAM subsidiary Siteco are installed to DUS® trunking rails and equipped with OSRAM LUMILUX T5 lamps. Pleasant for the installers: the low weight of the luminaries. In addition, sensors for presence detection were prepared and pre-programmed as plug and play modules in the aisles to cut down on installation time and to comply with the stringent construction schedule.
The light in the aisles is dimmed to 10% of total luminance via the integrated light management system, and is only then increased within seconds when an employee enters an aisle. Compared to a solution without LMS, Zalando saves 60% of energy with the selected lighting solution.
