52459 Inden: The aim of the settlement development was to use valuable resources more efficiently by a factor of 2 when building and living. Raw materials and building constructions were selected according to their environmental consumption and long-term costs. Regional building materials, timeless architecture, durable and maintenance-friendly constructions were given priority. Completion: 2018
| Size | 36 CU |
| Completion | 2018 |
| Project | new housing estate, EFH, 2-storey |
| Special features | The aim of the settlement development is to be at least a factor of 2 more efficient with regard to the resources of non-renewable primary energy, CO2 and non-renewable raw materials over a life cycle of 50 years than a KfW 55 (EnEV 2009) comparative building constructed in the usual local manner. The innovative approach is not only to use the service life of buildings to calculate resource consumption, but also to carry out a cradle-to-site analysis, which also includes the service life of building components and their transport distance from the manufacturer to the construction site. The settlement is the first settlement in Germany to carry out a simplified life cycle assessment with regard to resource consumption.
The first "Factor 4 House"The construction area is home to Germany's first "Factor 4 House", which will reduce resource consumption by a factor of 4 or 75% over its entire life cycle. During KlimaExpo.NRW until 2022, the building will be used as an office and exhibition building for the Factor X Agency. The topping-out ceremony was held at the end of 2017. |
| Energy | Holistic optimization of energy use. Avoidance of 4,375 t of greenhouse gases over the entire life cycle. |
| Building materials / Building Biology |
Holistic optimization of raw material consumption. Use of recycled building materials, partly timber construction. |
| Free space | Specifications in the B-Plan for garden design with native woody plants |
| Development | The building materials of the development were also optimized as far as possible with regard to energy, CO2 and non-renewable raw materials. Areas not driven on by cars e.g. in water-bound cover. |
Video (2018) "Factor X Settlement Inden Seeviertel"
| 2:33 min 12/17/2018 |
The construction sector is one of the biggest consumers of resources in Germany. With the "Seeviertel" new housing development, the municipality of Inden in the Rhenish lignite mining region, together with RWE Power, the Aachen-based Kathy Beys Foundation and the development company indeland GmbH, has set itself the goal of halving resource consumption. As the first settlement of its kind in Germany, the Seeviertel demonstrates how energy efficiency and resource conservation can be integrated into neighbourhood development right from the ground-breaking ceremony.
