Exclusive penthouses in the old city between the university and the Baltic Sea
Greifswald in Mecklenburg-Western Pomerania, Germany: In this vibrant university and hanseatic city, there is an unusual overlap in the centre of life of young and old. Some 12,000 students shape the urban landscape alongside agile senior citizens who love the Baltic Sea flair against a historic backdrop. In terms of living space in the exclusive historic old city, this means one thing: It's scarce! This is why the 6-million-euro project which was developed on the last free site of an industrial wasteland proved so successful. Not least because the living standards offered complement the highly sought-after surrounds.
Integrated system offering guaranteed quality
The development which dovetails harmoniously in the old city comprises three multi-storey buildings with a total of 81 flats, including penthouses with generously sized roof-top terraces, whirlpools and wellness showers.
The floor heating, laid with Fonterra Base snap plates creates a wonderfully warm environment. The hot water from the small district heating connection flows in zinc-coated steel pipes (Prestabo).
Drinking water hygiene was also the focus of attention. The challenge: The whirlpools and wellness showers considerably increase the need for hot drinking water (PWH) at times. On the other hand, the regular water exchange must be ensured even if used irregularly.
Ideally designed with Viptool Engineering
To solve these issues, using the Viptool Engineering program various simulation calculations were performed which ultimately led to, in part, considerably optimised nominal sizes: In the main distributor made of stainless steel (Sanpress Inox) where with a conventional design DN 76 would be necessary, it was possible to reduce to DN 64 whilst retaining the same supply quality. The connecting lines from the flow-optimised piping system Raxofix could be installed as DN 12 instead of DN 15 everywhere with the exception of the flats with wellness bathrooms. Overall this equates to enhanced drinking water quality and reduced material costs.
