The energy efficiency project at Weidmüller Interface GmbH & Co. KG is based on optimizing energy efficiency in the entire production system. This relates to both optimizing existing equipment and buildings, but also to cutting the energy required by existing machines and buildings when these are newly bought or procured. In the case of the individual machines and systems, attention is paid to achieving an optimum level of effectiveness and to possible recovery of the energy employed. The focus was on energy optimization for the transformers and the use of process heat. For the buildings, the focus was on heating, ventilation and cooling including intelligent control. 

Energy consumption for the energy-optimized systems compared to systems with conventional technology: : 55%, compared to total energy consumption in 2011: 28%.
