Osram LED solution supports the Havi Logistics sustainability initiative
Osram Lighting Solutions has drawn up a cross-location LED lighting concept for Havi Logistics. The basis for this were pan-European energy audits previously carried out by Osram in the European distribution centers of Havi Logistics Following refurbishment of the lighting, up to 80% in energy costs are now being saved thanks to efficient LED technology and intelligent light management in the cold storage centres.

The international logistics company Havi Logistics is active in over 30 countries in Europe, supplying leading 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, applying to LED technology, modern light management, less heat input and the cutting of energy costs.
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 for precisely determining the savings potential. This 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.
LED refurbishment at the Neu-Wulmstorf location
Projects for upgrading to LED technology have recently been carried out at several logistics centers in Spain, Portugal, Poland, Sweden and Germany. For example the Lower Saxony location of Neu Wulmstorf, one of the largest DCs of Havi Logistics with floor space of 14,000m². Two different Siteco LED luminaires are used according to the building or warehouse area in Neu Wulmstorf, connected to a light management system. Around 50 Siteco NJ700 LED highbay luminaires create a future-safe and robust lighting solution for the high warehouses and aisles between the freezers that have extremely cold ambient temperatures of around -23°C. The luminaires in the freezer area are equipped with single 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 down again to 10% general illuminance following a 30-second delay period.
Delay periods reduced to a minimum
The lighting concept also includes around 300 Modario® LED luminaires lighting aisles in the dry storage facility for example. Sensor modules were integrated into the Modario® trunking rails to control the aisle lighting in sections according to movement and levels of daylight. Three sensors were integrated in each aisle.
Delay periods can be minimised thanks to the very high detection quality of sensors used in the freezer and dry storage areas. This is an essential factor for achieving energy-efficient lighting, because modification is correspondingly quick from work lighting (100% dim setting) to general lighting (10% dim setting).
High savings with a short return on investment
Replacing obsolete T8 fluorescent lamps and HID (high pressure gas discharge) lamps of the old lighting installation with an innovative LED solution now provides enormous savings in energy and carbon dioxide. The input of heat in the cold store areas has also been reduced thanks to the new LED lighting concept.
Havi Logistics now saves around 1.7 MWh of energy and over 830 tons of carbon dioxide annually in Germany. The return on investment should be paid back within approximately 2.8 years. In addition to energy savings of up to 80% according to the specific hall area, the lighting level and quality of light was also significantly improved.
