Bredella direkt am Bahnhof Nord in Pratteln Mitte


The new district is to be developed on the basis of a holistic sustainability concept. This encompasses the following three domains: environment, social affairs and economy.

Although energy is a very important subject here, it is only one among many. For meeting the goal of building a district in line with the 2000-watt-society model, the underlying urban development concept is not the primary factor. The planning of the individual buildings and how they are built are of far greater importance. On the neighbourhood-plan level, the following aspects are most important in the context of the desired sustainability:

Quality of life

Inward densification of the settlement area is a key measure in sustainable planning, as it can prevent further consumption of cultivated and natural land. High-quality structural densification leads to diversity and interconnection, thus contributing to the quality of life and helping to create a sense of identity. 


A diverse range of possible uses allows many everyday purchases to be made in the new district itself or nearby, and on foot. This leads to an enlivening of the public space and enables contact between residents. The number of car trips to neighbouring centres is reduced and sustainable mobility, via bicycles, public transport and car sharing, becomes more attractive. A mobility concept shall define additional measures for optimisation of traffic flows and coordination of the various modes of transport (train, bus, tram, car and bicycle). Only with a mobility concept, will it also be possible to reduce the high number of car parking spaces that the building code currently still demands, as well as the number of not-particularly-sustainable parking spaces underground.

Energy generation

A third of the demand for electricity is to be covered by rooftop photovoltaic systems. Additional photovoltaic systems on the buildings are conceivable.

Energy supply

Bredella is in the territory of an energy network with sufficient potential to cover the basic demand for heat (heating and hot water). As a supplement or alternative to this, an anergy network is also conceivable. This is based on the fact that different uses also have different energy requirements, which can be used synergistically: Residential uses have a higher demand for heat than for cold.

For almost all other uses, the reverse is true, i.e. waste heat is generated, which can be used to heat flats if heat exchangers are used to transfer it to the anergy network and distribute it, then a heat pump is used to bring it to the desired temperature for heating the flats. Water storage tanks and/or borehole heat exchangers can be integrated into this anergy network for storage of heat during the summer months.


Today, the necessity of developing the settlement area in a climate-friendly way is hardly disputed anymore. In order to prevent a built structure from overheating in the summer months, a very wide range of measures are to be taken. The most important are as follows: thermal insulation of all buildings in summer by means of interior thermal storage mass, night cooling, outdoor sun protection, shaded places in the outdoor space, pools, greening of the outdoor space and of roofs, and purposefully planned ventilation of the entire site.

Fewer sealed surfaces

Bredella's outdoor spaces are to be made rich in variety and close to nature. An ecological compensation area along the tracks and flat green roofs make an additional contribution to the neighbourhood's biodiversity. Today's grey and almost completely sealed industrial site is to become central Pratteln's green lung.
