Abandon? Ex. Military? Shelters? World war? There are too many words to describe the Flak Tower in Vienna. Some people who know Flak tower always says that tower is not maintained and make scene of Vienna become so bad. In different perspective, there are big potential aspect that we can do to this towers and give them new identities and become landmark of the city. Nowadays, there is big issue about alternative energy in the world and Vienna was selected to host the PREMIER WIND ENERGY EUROPE EVENT. This event held by EWEA (European Wind Energy Association) in 2013. It is a conference about wind energy with several wind energy experts to discuss new wind energy development issues and new markets for wind power distribution. In combination with this event, it is a big chance to introduce a new energy in Vienna with wind farming ideas.
There are many advantages that exist in the Flak tower. The size of the tower in comparison with surrounding buildings will be positive issue to make this building become wind tower. The average height of the surrounding buildings are 4-6 floors, but Flak towers are about 10 floors height. The tower can catch strong wind and turn it into energy. The characteristics of these can be use to its advantages. The tower has a vertical space which can use to distribute the winds to all levels of the building. Moreover the advantage of these structures was not much use of a vertical column so as to maximize the potential of wind without any hindrance from the columns.
In the energy sector, the application of technology can be used to maximize the potential of wind. The implementation of wind farming concept to these Flak towers are using some of the wind catcher like a wind scoop, Wind turbine, and Regenedyne. The first element to catch the wind into this building is wind scoop. Process from this tool is to catch the wind from the environment with some shape to maximize wind gain. Mounting of this tool depends on tower location and city wind direction. Additionally, a big energy catcher from this building is Regenedyne. This tool is like an propeller which spins on the top of the roof to catch the wind. This tool is divided into several parts like wind catcher (sometimes like wind blocker to make directions to the winds), wind turbine (to process the energy from the wind), and energy storage to save the energy from the process. After being collected, energy is put into a storage and used to meet the building’s energy needs and Vienna’s energy needs.
Apart from producing energy, Flak towers can represent Vienna’s heritage. Vienna is the city of music. Mechanisms inside these towers can produce music by the wind collected. For example, using music box as the idea, a “plug and play” box can be constructed where visitors come and readjust the pegs in different slots. As the central core rotates with the wind, music is produced. In addition, wind chimes inscribed with names of the heros from the wars, are hung on the exterior, as light breeze passes thru, calming sounds vibrates in the air.
On the interior, the levels are divided into three zones according to the strength of the wind. From top to down and from strong to light, the top floors are research laboratories for wind farm, in the middle, are exhibition halls, and on the lower floors, symposium halls. The construction and materials used in the interior can help to reflect or divert wind to enhance visitors’ experience.
Making use of the height of these towers, wind farm is a practical solution to these abandoned towers. In addition, topics discussed at the 2013 PREMIER WIND ENERGY EUROPE EVENT can be put into use and researches can continue even after the event. Moreover with St. Stephensdom church located in the middle of the three pairs of towers, music produced by wind collected in these towers can enhance and echo the sound from the bell towers of the church. With the combination of Vienna’s music heritage and modern day energy solution, attention will be drawn not just to the Flak towers but to Vienna.
