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.
After comprehensive energy refurbishment of residential buildings or moving into energy-efficient new buildings, a deviation of the real energy demand from the energy demand calculated ex-ante can often be observed (performance or energy-efficiency gap). That means that the observed actual consumption is higher on average than the target consumption determined using static or dynamic calculation methods.

A new mixed-use urban district is being created in Oberursel which shall be used to develop and test an energy-plus concept for districts. Housing and commercial areas are planned on a roughly three-hectare site on Zimmersmühlenweg. Standards for energy-plus districts are being formulated that are based on the energy-plus standard for individual buildings.

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.
