Modernised Zumtobel Factory in Lemgo Saves 50% on Energy

Author: SSLDesign News Staff

July 8, 2010... Zumtobel completed the renovations of plants 1 and 2 at its manufacturing sight in Lemgo, Germany. Zumtobel says that the extensive renovations have improved the working conditions of around 500 staff and boosted productivity and quality. At the same time the renovations cut energy consumption by 50%.

The company managed to optimize the lighting of the plants by cleverly combining daylight and artificial lighting. Skillfully adding the abundant and free daylight provided the greatest scope to make savings.The number of existing skylights in the factory was increased by around 40% in order to increase the amount of incident daylight.

The lighting consistently used daylight-based luminaire control. The external daylight sensor installed on the building's roof measures the amount of incident daylight depending on the position of the sun. The Luxmate Professional lighting management system supplements this daylight with just enough artificial light to achieve the target illuminance level of 500 lux. This reduces the lighting installation's power requirement by up to 60%, depending on the time of day and prevailing brightness.
