New EnEff:Stadt projects online

Two energy-efficient urban districts in Landshut and Weimar are currently being focussed on by the EnEff:Stadt research initiative. Researchers are closely monitoring the Ludmilla housing estate in Landshut, which has been built using "energy-plus" construction, as part of the "+one" pilot project. In terms of refurbishing existing building stock, old buildings in inner city areas with a mixed structure pose a particular challenge. The "Old Zöllner District" model project in Weimar intends to demonstrate the economic and technical feasibility of providing highly efficient, energy-oriented refurbishment.

As part of the research initiative funded by the German Federal Ministry of Economics and Technology, assessment criteria, concepts and design tools have been developed for local authorities, the housing sector and the energy industry, and tried and tested in typical urban districts. At the same time, the realisation of energy concepts and their monitoring and measurement is also intended to implement the concept of integral planning. Through the consistent use of new technologies and intelligent planning procedures, the aim is to reduce the primary energy used throughout the district by at least 30 per cent.

Energy-plus housing estates will become increasingly widespread in future new-build schemes. The research project will assess the entire concept behind the housing estate in terms of its energy utilisation and also consider the impact of energy-plus housing estates on the energy supplier’s electricity grid.

Based on the integrated climate protection concept developed by the city of Weimar, the "Old Zöllner District" project intends to demonstrate the economic and technical feasibility of providing a highly efficient, energy-oriented refurbishment of old buildings in inner-city areas with a mixed structure. It is planned that the decentralised, largely self-sufficient energy supply shall use a large proportion of renewable energies.
