It’s a piece of fillet: with a mirror-like view of the Kiel Fjord and centrally located. If only the spectacular new property and building were not so surrounded by small and large streets! “The so-called KoolKiel building is a mixed hotel and residential building. We have a high level of traffic noise and commercial exposure here. Here is the KVG warehouse, where buses leave in the morning and evening and where we have a high level of noise or emissions, “says Klaus-Peter Juhl. He talks about a showcase project for urban development in Kiel. The husband of the Environmental Protection Agency has been accompanying her for a long time. It will be an 18-storey building with an extremely jumpy glass façade and the aesthetics of a Rubik’s cube. The design comes from the office of a well-known architect in Rotterdam – it would be really stylish if it were not for the constant noise from the townspeople, the bus depot and the swimming pools with parking spaces next door.
“If you look at the overall noise, we know from the study that we can easily get into the area that is dangerous to health – at least in terms of health care. That’s why we need to react. We’re giving planners or “Investors have something to help them make sure you can stay in your living room or bedroom even with the window open,” says Juhl.
Glass facade as sound insulation against city noise
We are in the office of Klaus-Peter Juhl in the city center. There are maps with red noise lit by traffic in Kiel. And there, two screens show the KoolKiel Tower with all its colors and clear beauty: the rugged façade allows for balconies and terraces. Inside and outside can hardly be distinguished. What stands out are the glass loggias. “The glass can be pushed sideways so you can use the outside area as you like – for sunbathing or the like. Otherwise sunbathing is not possible in this form. Then you have the traffic or other noise directly in bedroom or living room.There is the possibility of protecting areas with curtain-type glass facades, which means that you have a glass facade about 50 centimeters in front of the window that serves as sound insulation.This leads to a significant improvement of noise protection, “says Henning. Busch from the acoustics office of the same name on the keel.
“Urban Area”: Enabling living and business side by side
Busch is currently planning with these influential discs in the Mühlen district of Bad Kleinen: “It’s farther away and not as urban as the project in Kiel,” he says. “It is a former mill complex that was used to distribute and process grain. I think the grain came by train. And now there is a former not-so-present barn.” Gray like the GDR, but soon the nucleus of a new living district on Lake Schwerin. The thing is near the wide train tracks, which looks like a lot of noise. Further, an old mill is hidden and open green spaces can be seen. “You can probably imagine that if you are on the top floor, you have a beautiful view over the lake on one side. But on the other hand there is a lot of noise. It may not be so wonderful from the view. Now this has to be revived and there is speculation as to whether “urban area” opportunities can help here, “says Henning Busch.
Here, too, houses must take obstacles. In addition, Henning Busch shows a porous stone – a sound insulation material for the facade that brings good results with the windshield and air in the middle. The term “urban area” is important, he says. It is quite young and makes it possible to live in a noisy situation. The people there are protected in such a way that they can live and work side by side.
Compromises and mutual considerations
The acoustic engineer puts on the table plans for another quarter. In the urban area of Elmshorn there is a redevelopment area in which were the old facilities of the Kibek carpet factory. “These are big areas, a big skyscraper,” says Henning Busch. “It has been reused as a general residential area and there are areas adjacent to other industrial facilities. The flats are definitely under stress. An industrial facility that is doing something non-stop day and night makes noise, but you can fix it in a way. “Reduce the level, the ‘urban area’ creates opportunities there.”
All these processes gained momentum only as a result of the long-standing desire to live in the city and its densification. And even if many people think the opposite because of Corona: Without compromise, it is actually no longer possible in cities. “It’s always a duty to show mutual consideration,” says Henning Busch. “It’s like living in a palace. I can not wait to hear nothing from my neighbors. If one of the neighbors is celebrating, sometimes it’s noisy until nightfall. You can reduce this with structural measures, do not run away.” .
