The solarCity (in the Solar City or Solar City maps ) is a district created on the drawing board that offers around 4,000 people living space. It is located in the Linzer Feld on the Danube in Upper Austria and belongs to the Pichling district of Linz .
The social housing was built in a low-energy way, the basic idea in the planning was that fossil fuels contribute to the greenhouse effect and therefore their use should be avoided.
location
SolarCity is located in the northeast of the Pichling district in the south of Linz, on the Traun , not far from its confluence with the Danube. It belongs to the Pichling cadastral community.

History: planning and construction
In 1990 there were around 12,000 people looking for an apartment in Linz . The Pichling area, with its generous amount of space, its proximity to the Traunauen with small bathing lakes and the existing residential structure of single-family houses, offered an ideal place to expand the city. The architect Thomas Herzog , who built the Design Center Linz at the time , established contact with the internationally known architects Richard Rogers and Norman Foster . They designed inexpensive, energy-saving apartments for the settlement and entrusted the execution to the local architects.
Planning for the project began in 1992, and from 1999 the 1,300 apartments were built in stages over a period of six years. The total cost of the project was 190 million euros, almost two-thirds of which went to residential construction and the costs of infrastructure only made up one-third of the total.
Infrastructure
The center of solarCity is the local square with a bank, department store, tobacco shop and coffee shops. The employees of the district office and the pastoral care center take care of interpersonal issues . Families and children are taken care of by the family center, two kindergartens and the school center, which includes an elementary school, a secondary school and an after-school care center. In the north of solarCity there is a local recreation area directly afterwards . Since September 2005 solarCity has been connected to the public transport network by line 2 of the Linz tram ; It takes you to downtown Linz within half an hour.
Supply and disposal concepts
In terms of environmentally friendly settlement development, supply and disposal were included in the overall considerations when planning solarCity.
power supply
At least one third of the hot water in solarCity is generated by solar energy. The remaining two thirds are covered by district heating.
Sanitation
Most of the wastewater generated is disposed of via the municipal wastewater network . A rainwater management system with hollows, trenches and retention basins ensures that the rainwater seeps away on site.
The alternative wastewater disposal is still in the experimental stage, currently in 88 residential units and the school, disposal by means of urine separation.
The separate drainage and collection of wastewater enables the extraction of concentrated fertilizer from urine and the remaining wastewater can be cleaned efficiently. For the time being, urine can after the upper Soil Protection Act has not yet been applied to agricultural land and must therefore currently still be introduced into the public sewer system .
Gray water and faeces are drained together. The solids are then separated from the liquid in the compost separator. The pre-composted contents of the separator are used as fertilizer in agriculture. The remaining nutrient-poor wastewater is treated in a plant -based sewage treatment plant . If the sewage treatment plant has positive discharge values, the aim is to discharge the treated wastewater into the Aumühlbach.
Awards
- In 1998 the United Nations ( UNCHS ) announced a competition to improve the living environment, solarCity received the “best practice” award.
- In 1999 it was nominated for the Environmental Award 2001 by the Earth Society Foundation , an NGO based in New York.
- At the second international conference business and municipality - new partnerships for the 21st century in Bremen in April 2001, a jury of experts from the bremen initiative selected solarCity as one of the five best projects in the world in category 1 of the bremen partnership award .
