After a series of pan-European energy audits by Osram in the European distribution centers of Havi Logistics, Osram presented the international logistics specialist with a cross-location LED lighting concept providing up to 80% savings in energy costs thanks to efficient LED technology and intelligent light management in the cold storage centers.
Havi Logistics is active in over 30 countries in Europe, supplying restaurant chains in the system catering sector from over 60 distribution centers (DCs). A five-year sustainability initiative specified that all locations should be upgraded to a uniform, energy-efficient lighting concept.
“It's our aim to cut energy costs by using modern LED technology and integrating intelligent light management. We also want to reduce the level of heat input in the cold and deep-freeze stores caused by conventional lighting,” said Michael Buß, head of technology at Havi Logistics.
Osram Lighting Solutions (LS) carried out pan-European energy audits to analyse the locations with regard to lighting technology and energy. Osram used its so-called data logger at all German locations for precisely determining the savings potential, which documented the occupation frequency of various areas and levels of daylight and artificial light over the course of two weeks. The savings potential identified was between 20% and 80% according to the specific area.
“In this way a lighting concept could be drawn up for the various building or warehouse areas, and based on that the energy savings potential as well as investment costs and payback periods could be precisely determined according to the particular location,” said Christian Oswald, project manager at Osram.
Upgrades have recently been carried out at several logistics centers in Spain, Portugal, Poland, Sweden and Germany. One example at the Lower Saxony location of Neu-Wulmstorf, one of Havi’s largest DCs with floor space of 14,000m², used two different LED luminaires connected to a light management system. Around 50 LED highbay luminaires create a future-safe and robust lighting solution for the high warehouses and aisles between freezers that have extremely cold ambient temperatures of around -23°C. The luminaires in the freezer area are equipped with individual sensors from the "Step Control" functional package. If people or vehicles are registered in the sensor detection range, lighting is switched to 10% general illuminance and 100% work illuminance levels. If no people or vehicles are detected, the luminaires dim again to 10% general illuminance after a 30-second delay period.
Installation itself is partly very simple thanks to 1:1 replacement of the obsolete luminaires, and supplementary wiring for the light control is not required.
