Inden Seeviertel: The whole life cycle at a glance

The construction industry is one of the major consumers of resources in Germany. With the new "Seeviertel" development area, the municipality of Inden in the Rhenish lignite mining area, together with RWE Power, the Aachen Kathy Beys Foundation and the Entwicklungsgesellschaft indeland GmbH development agency, has made it its goal to halve the consumption of resources. As the first estate of this kind in Germany, Seeviertel shows how energy efficiency and the conservation of resources can be integrated into district development from the ground-breaking ceremony on.

With the Inden-Seeviertel Factor X development area, the project partners intend to demonstrate how a residential area can be built and lived in in a way that saves resources. "Factor X" means that, when building and living in the development, resources are used X times more sparingly than in conventional buildings. In Seeviertel, the estate will mostly be "Factor 2": In comparison with conventional estates in the region, the buildings in the new district will save at least 50 per cent of greenhouse gas emissions, non-renewable primary energy and raw materials across a life cycle of 50 years. It is even estimated that a "Factor 4" model house in the Seeviertel area will achieve 75 per cent savings. But it is not only the environment and the climate that benefit. The homeowners themselves also benefit from a building that functions for several generations and provides flexible habitability for every situation in life. This reduces energy consumption and costs.

Engine for progress:

  • preventing 4,375 tonnes of GHG over the entire life cycle
  • 50% less resource consumption
  • the first estate of its kind in Germany
  • comprehensive optimisation of energy use and raw material consumption

On the 21st of September 2015, KlimaExpo.NRW included Seeviertel-Inden as the 114th step in its showcase of achievement.

Holistic optimisation of the estate's life cycle

At Seeviertel-Inden, because of the holistic approach taken by the project partners, a particularly resource-friendly estate is being created, which has been optimised for its entire life cycle. "When planning, we discovered that there are many different ways of achieving the Factor 2 standard. In order to provide the property owners and architects with creative leeway, we have developed a construction handbook that explains the different design options. One can, therefore, check quite easily whether a house achieves the required 50 per cent of resources used in conventional housing," explains Klaus Dosch, Project Manager.

In addition to this, roads and pathways are primarily made of recycled materials from the demolition of villages in the Inden opencast mining area and other domestic construction products are given preference. This strengthens regional added value and the project also makes a positive contribution to structural change in the region.
