With 168 production sites in 32 countries and 19 main development centers in 9 countries, the ZF Group is one of the world’s leading automotive suppliers. ZF continually strives to enhance the efficiency of its global production sites. Sustainability is a core component of ZF Group‘s strategy, with goals such as achieving complete climate neutrality by 2040. To minimize their environmental impact, conserve resources, and improve their bottom line through efficient energy management, the ZF Group decided to implement an energy management system in accordance with the international standard ISO 50001. Previously, the lack of detailed data on their energy consumption made it difficult for them to track their sustainability efforts and goals. They were unable to monitor the progress of their mandatory sustainability targets for electricity, gas, compressed air, and water consumption. The only data available came from monthly energy bills, reported up to two months after the energy was consumed, which made it impossible to take timely countermeasures. Real-time, detailed data from their plants was not available to the ZF Group.
