Since 1995, the Neckarsulm site has regularly been certified in accordance with the Eco-Management and Audit Scheme (EMAS) of the European Union, and it was once again certified in 2014. A key factor for certification is that evidence is provided of compliance with applicable law and of continual improvements in environmental protection. The Audi site in Neckarsulm therefore searches for new solutions in many areas, for example to reduce energy consumption, CO2, dust and solvent emissions, and to increase waste recycling while minimizing total waste.
The logistics center at Audi Böllinger Höfe, which went into operation in March 2014, is a good example of the compatibility of economic, ecological and social sustainability. The new logistics center brings together the processes of five previous logistics sites. This consolidates the flow of goods, reduces transport and transfers truck traffic from the city of Heilbronn into the industrial area. Construction work in the city of Heilbronn, for example for the 2019 Federal Garden Show, made use of the earth removed when building the logistics center. In cooperation with experts and the local environmental associations of NABU and BUND, Audi has taken ecological compensatory measures such as a biotope with ponds and vegetation planted as a protected area for amphibians. An amphibian guidance system has also been installed.
With the building itself, the focus was placed on energy efficiency. In addition to plenty of daylight, LEDs are used to illuminate the logistics center, switched by light sensors and presence controls. The building’s efficient ventilation retains heat in combination with generally lower heating requirements. Water is partially heated with solar energy and the material lifting devices feed energy back into the system. An energy management system identifies high energy consumers in the system so that countermeasures can be taken to further reduce energy consumption.
Audi uses greywater for internal sprinkler systems and processes rainwater to be used at the center, so that less drinking water is required.
