Salina Raurica Ost Masterplan, Pratteln , Switzerland

The Salina Raurica East site is located in the border triangle of Switzerland, France and Germany in the canton of Basel-Landschaft. Not far from Basel City and situated directly on the Rhine, it is embedded regionally and supra-regionally in the catchment areas of other major Swiss, French and German cities. At the transition from the more densely populated Basel conurbation to the more scenic settlement areas of the Basel region and Aargau, a diverse, lively neighborhood is to be created which, as an alternative to the urban neighborhood, is oriented both to the very widespread desire for living "in a rural context" and to the objectives for a resource-saving, contemporary, dense residential and working neighborhood. For this reason, the development area makes use of the spatial, infrastructural and social potentials that already exist in large numbers on site today. The equal mobility of all road users also plays a key role in the development of the district.
In order to ensure the energy-sustainable development of the area, an energy concept was developed in variants for the operation of the buildings and their use to be CO2-neutral. It was essential to consistently include locally available regenerative energy sources in the considerations and to combine the heat and electricity sectors in a sensible way:
Waste heat is used for heating purposes and to provide hot water for domestic use, for example from buildings or the neighboring wastewater treatment plant, the third largest in Switzerland.
Photovoltaic systems generate electricity; power-to-gas (P2G) systems are used to store this energy. Geothermal energy and ground water are used as sources and for sinking heat.
Combined heat and power generation regeneratively provides district heating.
Further tasks were the analysis of small-scale air flows within the area and, based on this, the development of measures to reduce the heat island effect.
With regard to the residential development, the so-called building massing was also of importance in order to be able to prove that all flats are gaining daylight in a way that is appropriate for their intended use.
