Since the third expansion stage was completed, the Dortmund stadium is among the largest stadiums in Europe. For its smooth operation, the sports venue in the Ruhr area relies on the smart pump technology provided by the Wilo-Stratos Maxo.
At 62 metres high, the eight yellow floodlight towers on the Signal Iduna Park are a distinctive feature of the Dortmund skyline. With space for 81,365 fans, Dortmund’s stadium is the biggest in Germany – the legendary south stand, known as the “Yellow Wall”, is Europe’s largest standing-only terrace.
“In times of increasingly scarce resources and increasing environmental pollution, it is of course essential for us to take up and deal with ecological consequences as well”, states Carsten Cramer, BVB-CEO. “We consider responsible energy use and the associated reduction of harmful emissions to be our fundamental and essential economic goals. This includes increasing energy efficiency.”
In terms of water supply and disposal in general, football stadiums have a very heterogeneous performance profile. During the game water use drops significantly, however, it increases dramatically at half-time, not least because of the heavy use of sanitary facilities at this point. For many years the home of Borussia Dortmund has counted on the energy efficient, reliable and high-performance products of Dortmund technology company Wilo. From the water supply for the VIP areas, to the changing room heating and the undersoil heating system: Wilo product solutions create a green environment. Since 2019, new Stratos Maxo models have been providing the supply for the south stand.
The new Stratos Maxo for HVAC and drinking water applications in large buildings offers an Energy Efficiency Index (EEI) of ≤ 0.19 to ≤ 0.17 depending on the model. This is based on optimised energy-saving functions like Multi-Flow Adaptation and No-Flow Stop. With its high connectivity, the Stratos Maxo can be flexibly integrated into a wide variety of applications.
