1 LED LIGHTING FOR COLD STORAGE Madrid, October 16 Maarten de Graaf Didyouknowthat? It takes 0.65KWh of air conditioning energy to cool down every 1 kwh of lighting heat.

7 Business case 1 Global Phamarceutical Company Background. Existing building Project started in 2010 as pilot site for world wide roll-out for energy efficient lighting. Overall goal was toestablishif itwouldbepossibletoimplementled lightingworld-widewitha ROI of < 3 years, without compromisingthe qualityof lighting. It concerned an existing Global Distribution Centre. Warehouses 12 meters Warehouses 6 meters Cold Storage 12 meters Offices, meeting rooms, hallways and restaurant Loading docks and parking areas and outside lighting. In totalmore then6000 lampswerereplacedbyled lighting

9 Annual Savings leading to 2.8 years ROI Additional savings After implementing dynamic switching with motion detectors, additional energy savings of 40% were realized. (=16% of the original energy consumption) Because the LED lighting does not generate much heat, there are substantial savings in air-conditioning. Based on the extra aircosaving, the energy saving result of the coldstoreis now > 100% according to the customer.

The clientneededlightinglevels up to1000 lux in theirproductionarea forcamera qualitycontrol.
