Which is the highest industrial building in the world?
I believe, it is the building of Unit K of Niederaussem Power Station (
http://www.statik.bv.tu-muenchen.de/...ekraftwerk.htm ), which is 172 metres tall. The exhaust of these power station are conducted through world's highest cooling tower ( 200 metres) in the air.
Unit K of Niederaussem Power Station is the highest "real" building in Germany outside Frankfurt/Main.
