Pilot Projects for Energy Efficient Cities

Pilot projects are to show how energy efficiency in communities can be improved via intelligent use and networking of innovative technologies, planning and management methods. The EnEff:Stadt research initiative identifies assessment criteria and concepts as well as planning aids for municipalities and other actors, such as the housing industry and public utilities. In the context of the initiative, exergetically and economically optimised combinations of measures are developed for defined quarters. The implementation of these measures acts as an example and their effects are measured.The research is carried out in typical housing schemes. Development results are tested and assessed in typical city quarters. At the same time, the realisation of energy concepts and their monitoring and measurement is intended to implement the concept of integral planning. The aim is a minimum 30 percent reduction in primary energy use in the entire quarter through consistent application of new technologies and intelligent planning. The transfer of research and development results will provide the specific expertise needed to meet the urban development challenges of the future.

Model city district refurbishment: Weingarten West, Freiburg

The planning, implementation and measurement-based analysis of the energy-oriented refurbishment of the Freiburg city district Weingarten West is all being realised with the goal of a 30% reduction of primary energy consumption. The passive-house-standard refurbishment is to be demonstrated with the example of a 16-storey high-rise building. One key objective is stronger networking of the parties involved: building society, energy supplier and tenants.

Ludmilla energy-plus housing estate, Landshut

Energy-plus buildings epitomise the energy efficient integration of buildings with systems equipment. The aim of the project is to conduct building- and energy-oriented investigations by means of intensive monitoring. In addition to assessing the district concept in terms of the energy utilisation, the impact of energy-plus housing estates on the energy supplier’s electricity grid will also be considered.

Energy-based optimisation of the Hamburg Water Cycle in the Jenfelder Au urban neighbourhood

The new Jenfelder Au urban neighbourhood is being created on the site of a former army barracks in the Hamburg district of Wandsbek. It will provide a total of 770 accommodation units for around 2,000 residents. This pilot project aims to intelligently combine urban wastewater management with energy provision and urban design aspects.

Energy Strategy Berlin Adlershof 2020+

With the cluster project High Tech – Low Ex, a concept for an energy-efficient further development of the Berlin Adlershof science quarter was developed from 2011 to 2013 with the aim of achieving 30 % primary energy consumption compared with “business as usual”. The project is being realised in several sub-projects until 2016.

The Community of Wüstenrot: Energy-independent by 2020

Wüstenrot is set to become energy-independent by 2020: scenarios for the development of renewable energies are being calculated based on a 3D urban model, strategies for economically utilising this potential are being developed and measures for increasing the energy efficiency of the existing building stock are being investigated. An energy-plus housing estate is being implemented as a model, which will have cold local heating provided via an agrothermal power plant and intelligent load management.
