09. Oct 2013 - Germany, Austria, Switzerland: Three energy-efficient cities cooperate

more details

Their population density and infrastructure means that cities make a considerable contribution to the development of energy efficiency. Energy-efficient and CO2-mitigating structures used in the utilisation and supply of energy can be achieved more cost-effectively and quickly if as many projects as possible are initiated as part of a holistic concept with many parallel measures. For this reason the “Energy-efficient cities” cooperation between Karlsruhe (D), Salzburg (A) and Winterthur (CH) was launched at the end of September. The aim of this D-A-CH collaboration is to intensify energy efficiency measures in the municipal regions and to promote mutual learning through the regular professional exchange of experiences and ideas. The German contribution, “Energy efficiency in Karlsruhe”, is also a pilot project in the EnEff:Stadt research initiative.

Project in two phases

It is intended to achieve the goals of the cooperation in two phases. In the first phase (concept phase), as many players as possible will be focussed on in order to prepare the ground for a concerted second investment and organisational phase. The second phase is aimed at implementing as many of the planned projects as possible and examining and sharing their criteria for success among the three cities.

Collaboration for cities of the future

With their cooperation, the cities of Karlsruhe, Salzburg and Winterthur are planning to promote research and development in the field of energy efficient cities. The D-A-CH project is being funded until the end of 2014 by the German Federal Ministry of Economics and Technology, the Austrian Federal Ministry for Transport, Innovation and Technology and the Swiss Federal Department of the Environment, Transport, Energy and Communication. This shall be followed by a five-year investment and implementation phase from 2015.
