Sporting challenges: Grundfos and stadiums

Meeting demands

Spectators flock to stadiums to cheer on their teams and experience the emotion of winning and losing. The players and athletes feel the weight of expectation and the pressure of competition. All the while, the infrastructure and systems installed in stadiums work together to ensure everything runs smoothly so the athletes and spectators can concentrate on the joy of sport.

The pressure is on
One of the biggest challenges in modern stadiums comes when there is a break in the action. While the action is unfolding in front of the spectators, there is practically no demand for water; but as soon as there is a break in the action, the demand for water increases dramatically. This places massive demand on the pumping and control systems in the stadium to be able to deliver the required water pressure level. How Grundfos has met this challenge in stadiums around the world is one of the themes you can read about here.

Multi-purpose flexibility
Stadiums are often also multi-purpose arenas that can host concerts and other events. Many stadiums are also integrated into larger complexes containing other sports halls and arenas, as well as offices, parking, hotel and conference facilities, shopping and more. A complex pump system integrated with a complex hydraulic system allows optimisation of the whole system and maximizes energy efficiency, as demonstrated by the SAP Arena in Mannheim, Germany, which is featured in this article.

The playing surface
Top footballers and other athletes require an absolutely smooth and even playing surface in the best possible condition to deliver their best performances. At the same time, modern stadium design often deprives a grass pitch of light and air. This, combined with the multi-use of many stadiums, places even greater demands on the optimization of the drainage and watering installations.

Take a look at just a few of the many stadiums around the world that have chosen to install Grundfos systems to meet these challenges.

The Bird’s Nest

One of the largest stadiums on the planet
Opened in 2008 the National Stadium in Beijing is commonly known as the Bird’s Nest, due to the 36 km of unwrapped steel that envelops the stadium and its roof, making the stadium resemble a gigantic bird’s nest. The stadium seats 91,000 spectators and is one of the largest enclosed spaces in the world.

Four corners
As one of the largest stadiums on the planet, the Bird’s Nest presents one of the greatest challenges for a pressure boosting solution. The stadium designers answered the challenge by installing Grundfos pumps and controllers. Installed in each of the four corners of the stadium, a Grundfos Hydro 2000 MEH pressure boosting solution ensures a steady supply of water. The Hydro booster systems control the 18 Grundfos CR/CRE multi-stage pumps that form the basis of the pressure boosting solution. Each pump has its own control box.

Drinking water
Grundfos pumps also supply drinking water to the spectator seating areas. Eight complete Grundfos Hydro 2000 ME water supply systems make sure that not one of the 91,000 spectators will go away thirsty. A further 16 electronically speed-controlled CRNE multi-stage pumps around the stadium guarantee reliable supply to all 12 sections of the National Stadium.

Unique specifications
The Bird’s Nest is a unique stadium with unique design specifications. With its extensive experience in stadium solutions, Grundfos was able to meet the specification requirements. Coupled with a strong service team in China, a high-level of reliability and energy-efficiency, Grundfos was the obvious choice for this fantastic project.

SAP Arena

Flexibility required
The SAP Arena in Mannheim, Germany is a great example of a modern, multi purpose and multi-functional stadium complex. With a total floor area of 48,300 yd2 (44,200 m2) the arena is home to events ranging from ice hockey and handball matches to concerts and conferences.

Conversion
To maximize utilization of the arena, fast conversion from ice rink to handball pitch, concert hall or theater stage is essential. Using state-of-the-art technology, the stadium can be converted from one purpose to another in less than 12 hours, allowing the arena to host completely different events over the course of a single weekend.

Single-source supplier
When it comes to state-of-the-art technology in the field of pumps, Grundfos is right at the front of the field. This was one of the reasons why the SAP Arena contractor Imtech Deutschland chose to single-source the pump solution to Grundfos. By single sourcing, the contractor ensured technological compatibility and easy maintenance. And with a full range of pumps for building services, Grundfos was in position to supply all types of pumps and controllers.

Speed-controlled
The arena’s main pumps are all speed-controlled and equipped with frequency converters, so they operate in the optimum output range at all times. This provides energy savings and simplifies the overall network by eliminating the need for expensive control valves, while also making hydraulic adjustments more straightforward.

All area access
Grundfos supplied the pumps for all areas of the stadium, including the water supply, heating, refrigeration and air-conditioning. With Grundfos controllers installed, the pumps in the heating and refrigeration sectors could also be seamlessly integrated in the arena’s central monitoring system by LON-Bus, allowing them to be monitored for faults around the clock.

Luz Stadium

A sporting cathedral
The design of the Luz Stadium in Lisbon, Portugal was based on the image of a cathedral. For many fans, football is almost a religion and the stadiums where matches are played are its cathedrals, where fans can worship their idols.

More than football
While the Luz Stadium is the largest sports arena in Portugal, with room for 65,200 spectators, it is also a multi purpose venue. For the players it provides four locker rooms, warm-up areas with a conditioning system that replicates the external temperature for players to exercise in, leisure areas for players as well as saunas and medical facilities. But with a total interior area of around 179,000 yds?/gal (150,000 m?/l), it also comprises restaurants, shopping areas and other non-sporting facilities.

Keeping the pitch perfect
Grundfos supplied the irrigation pumps that ensure the pitch is in perfect condition at all times. Grundfos NB pumps and a Hydro pressure boosting system keep the advanced irrigation system running, so it can irrigate different sized sectors and irrigation outlets simultaneously.

Air conditioning and more
The stadium itself and the indoor hall use independent centralized air conditioning systems featuring Grundfos TP and LM pumps. These are completely automated and integrated with the centralized technical management equipment via Delta 200 control panels. Grundfos also supplied a Hydro2000 MF 3xCR8-100 pressure booster system, as well as the pumps for the wastewater drainage, heating and ventilation systems.

Global and local
In Portugal, Grundfos was able to draw on a wealth of experience in supplying reliable, energy-efficient and high-quality pumping solutions for sporting stadiums around the world. This was coupled with a strong local presence that could guarantee on-going technical support and maintenance services once the solutions were installed. Combining global experience and know-how with local presence is one of the main reasons why Grundfos is often chosen as the preferred pump supplier for stadiums and sporting events around the world.
