Intelligent lighting technology saves energy
The branch of AGRAVIS Technik Weser-Aller GmbH in Walsrode is brand new. The site in the Honerdingen commercial area has been properly fitted out for performance and service in line with customer requirements. There are lots of new and used agricultural machinery, small devices, accessories and spares on the 15,000-square metre site. Customers and employees will find very few light switches in the building.

"In many rooms they are simply not needed," says Norbert Wöhlke, representative of AGRAVIS Technik Weser-Aller GmbH. In offices and meeting rooms, as well as in wet areas and cahnging rooms, the lights are only activated by sensors when really necessary – i.e: if someone is this these areas. When the rooms are exited, the light quickly turns off. Energy-saving LEDs are used in all lights in the site. The Walsrode branch is the first technology site of the AGRAVIS Group with a fully integrated LED lighting concept, in which the individual elements communicate with each other.
"LEDs have long been the standard lighting for new buildings and modernisation," stresses Jörg Fahrenhorst, head of Energy Service at AGRAVIS Raiffeisen AG. The procurement costs, that have now fallen considerably, are typically amortised over a few years.
AGRAVIS Raiffeisen AG worked with Sonertec GmbH from Dörpen as a partner in the development and realisation of individual LED concepts. "We have been active in the LED area since 2009 and offer a full service from light planning and selecton of LED elements to commissioning and training for installation companies," explains Sonertec shareholder Marc-André Themann. He is convinced of the market potential of the technology and expects demand to grow further in the coming years – although government subsidies have been reduced considerably. "LEDs no longer need this support," says Themann.
in order to develop a suitable lighting concpet for the technology site in Walsrode, the entire building was simulated in 3D. The results are clear. The various LED lights – panels, light ribbons, damp-proof lights – ensure consistent, practically glare-free and shadow-free lighting everywhere. "Working is very pleasant," reports agricultural machine mechanic Daniel Seemann, as he services a tractor and no longer needs additional hand torches. In the workshop, the LED light ribbons are controlled depending on the amount of natural light. The prescribed light strength is therefore always guaranteed. This saves energy costs and ensures work is safe.
In the spare parts warehouse, the sensors are controlled so accurately that only the lights directly around the warehouse employee work at full strength, all the others are dimmed to 30 percent power.
Nobody has to worry any more that LEDs are cold light. "We use pleasant light colours, which correspond to the working environment," says Marc-André Themann. 50,000 operating hours are realistic for these lights, say the experts. "And they are almost maintenance-free." The energy service of AGRAVIS Raiffeisen AG can check how the energy consumption in Walsrode develops against comparalbe locations. This will make the advantage of intelligent LED lighting visibly clear.
