Badhus – Industrilandskapet i Norrköping Norrköping har behov av ett nytt badhus. Centralt i staden, längs Motala ström, finns Industrilandskapet som till stor del består av kulturell och vetenskaplig verksamhet men har en lång historia av textilindustri. Det nya badhuset är placerat i detta område; på ett befintligt vattenkraftverk. Syftet med projektet är att tillvarata Industrilandskapets kontrastrika själ, förstärka de rum och potentiella mötesplatser som finns samt ge Norrköping en möjlighet till friskvård och sportutövande. Målet är att visa hur en ny byggnadskropp relaterar och anpassar sig till den kulturella, platsspecifika och historiska kontexten. Byggnaden intar formen av en rektangel som skjuter upp ur slänten, likt en bergsrygg som sluter platsen. Byggnadskroppen aktiverar befintliga kvalitéer såsom den gamla stenbelagda trappan i väster och universitetsparken vid vattnet i söder. Byggnadens norra sida syftar till att ta emot och avsluta rutnätstaden i skala och uttryck. Den södra sidan av byggnaden tillsluter och definierar strömrummet med sin långsträckta fasad. Byggnadens interiör vänder sig utåt mot strömrummet så att det inifrån skapas en öppenhet åt söder gör industrilandskapet till en del av byggnaden. På entrévåningen ligger bassängerna vars vattenytor är visuellt kopplade till Motala ström i flera nivåer. Sutterängplanet inhyser omklädningsrum, det befintliga kraftverket samt fysioterapiavdelning med motionssal. / Public Bath – The Industrial Landscape in Norrköping   Norrköping is in need of a new public bath. In the centre of the city, along Motala ström, the industrial landscape is located. This area hosts cultural and scientific activities but has a long history of textile industry. The new public bath is located in this area on an existing water power plant. The aim of the project is to maintain the contrasty soul, enhance the spaces and potential venues that already exist and give Norrköping a possibility for wellness and exercising. The goal is to show how a new building adjusts and relates to the site specific and historical context. The building is shaped as a rectangle rising from the slope. It activates existing qualities such as the old stone stairs in the west. The north side of the building aims to receive and end the grid city in scale and expression. The south side with the long façade defines the river space. The interior faces the river and creates openness towards the south. Thereby the industrial landscape becomes part of the building. The swimming pools are located on the entrance floor and the surfaces of the water are visually linked to the river. The changing rooms, the power plant and the physiotherapy are placed in the basement.

Phosphorous (P) has been found to be the limiting nutrient in freshwater systems, directly affecting rates of planktonic growth. The P circulation is very complex, and its pathways through lake systems are difficult to determine. Motala Ström is the biggest watercourse in the south-east of Sweden and an important source of P to the Baltic Sea. The aim of this study is to conduct a P mass balance analysis of the lakes Roxen and Glan over a period of time. The analysis will also include a quality control of the concentrations data. The P concentration data used in this investigation were collected from the Motala Ström River Association, consisting of seasonal or monthly concentration data of Tot-P during the period 1960-2010. Daily water flow data used in this study were modelled by the Swedish Meteorological and Hydrological Institute (SMHI) using the S-HYPE model. P concentration deviations from monthly averages at each sampling station were calculated, followed by a seasonal Mann Kendall trend analysis. At five out of eight sampling stations, negative trends were detected, indicating decreasing concentrations. The exception was the outflow from lake Glan, Stångån and Finspångsån. Linear interpolation of P concentration data was performed to create daily data for the period 1980-2010. Following interpolation, daily transport values were calculated and summed up to annual values. Lake Roxen has acted as a source of P during the whole period 1980-2010, except for one year. Lake Glan has acted as a source during 22 of the 31 years. There is a tendency of Glan to become more of a source over the years, which is in line with the deviation observations, but variation between years makes it necessary to analyse also future data in order to establish any possible trend in P transports. Before construction of wastewater treatment plants, the lakes were certainly sinks of phosphorus. But at least for Roxen, the switch from sink to source was completed before 1980.
