1. Allianz Arena, Germany
When it comes to advanced stadiums, the first thing that comes to mind is the Allianz Arena in Germany. It is located in the northern part of Munich, Germany. It was officially opened in April 2005. Since the 2005/06 season, it has become the new home of Bayern Munich and Munich 1860. The stadium cost a total of 340 million euros to build.

From a distance, the stadium looks like a translucent shell. German fans gave it a very vivid nickname: Schlauchboot . The facade of the stadium is composed of 2,874 ETFE materials, of which 1,056 can shine during the game. More than 300,000 LED lights are placed in the arena shell, allowing 16 million colors to be displayed. The interesting point is that the stadium will light up a different color for each game-such as red for the Bayern Munich home game; blue for the Munich 1860 home game; white for the German national football team; when the stadium is a neutral ground, White will also be used. Because the stadium at night is a huge luminous body, the Munich police insist on the use of monochromatic lighting (only white, blue, and red) for the stadium to prevent drivers from being distracted by changes in lighting.

Let’s talk about the ETFE material used externally. EFTE has the characteristics of high dirt resistance and easy cleaning, so dust is not easy to attach to the stadium facade, and the main dirt on the facade can usually be cleaned by rainwater. The cleaning cycle of EFTE materials is about 5 years. ETFE can also adjust the degree of shading and light transmittance by controlling the amount of inflation, effectively using natural light, and at the same time playing the role of heat preservation and heat insulation.

In addition, the Allianz Arena also has a huge sensor network, which can sense potential fire hazards.
The stadium is equipped with 4600 detectors responsible for detecting fire, and there are also 600 manual call points in the audience area, which can artificially sound the fire alarm. If the alarm is true, the signal will be sent directly to the fire department in Munich. In addition to the advanced design of the stadium, the Allianz Arena is also the first stadium in Europe to adopt a smart ticketing system. Fans can quickly enter the stadium through smart tickets and use the tickets as electronic wallets. The familiar “Siemens” also cooperates with Allianz Stadium, the direction of cooperation is the intelligent building infrastructure and energy management of Allianz Stadium, digital enterprise and Internet of Things solutions, stadium maintenance solutions, etc.
2. Veltins Arena (Veltins Arena)
Veltins Arena is located in Gelsenkirchen, Germany. It is the home stadium of the Bundesliga team Schalke 04. The original name of the stadium was Arena AufSchalke. On July 1, 2005, the naming rights of the stadium were given to the famous German brewery Veltins. The ceiling of Veltins Stadium is switchable fiberglass, coated with PTFE (non-stick coating), supported by 24 steel supports.
The roof can not only block rain and snow, but also reduce the sound inside the stadium by 105 decibels. In this way, you can dedicate yourself to the game and shout to your heart’s content.
In addition to the roof, the south stand of the stadium, the turf, and the supporting irrigation system and heating system can all be moved to the outside.
The turf can be irrigated and heated through a series of metal pipes 25 cm wide and 300 meters long. At the same time, the pipes can also move back 16 meters along with the turf and irrigation system to expand the stadium capacity.
3. Saint-Petersburg Stadium
The St. Petersburg Stadium is like a spacecraft parked on the shore of the Gulf of Finland. The spacecraft is about 79 meters high, has seven floors, and has a dome supported by eight large masts.
This stadium can also play a trick to “move the world.”
The retractable part of the stadium roof uses ETFE material, which can protect the stadium in bad weather and can also be used for projection purposes. Therefore, the stadium can hold events throughout the year, even in severe winter, the temperature in the stadium is still 15 degrees Celsius.
In addition, the venue is also equipped with a hot air inflatable membrane structure, which can melt snow in winter.
The lawn in the field adopts a swing-out type, which can be moved by a sliding pitch motor.
When large-scale events such as concerts are held, the lawn will be moved outdoors, which not only expands the space for the audience, but also protects the lawn to the utmost extent.
