The CONCERTO project in Redange, Luxembourg covers more than a tenth of the area of the country. The Redange canton is an agricultural area with ten villages and 14,000 inhabitants. Together with other communities, its objective is to switch over to renewable energy supply.

Redange already has a reputation in Luxembourg as a pioneer in energy efficiency and renewable energy. The project activities are a further step in the direction towards greater sustainability.

In Słubice the CONCERTO project is developing a biomass master plan. The district heating company is planning to modernise the town´s heating plant and change the coal burning heating system into a biomass systems. In addition, a study about the area´s biomass potential will be elaborated in order to create local markets for wood, energy crops, biogas, short rotation willow and straw.

The association of municipalities Weilerbach is located close to Kaiserslautern in western Germany. It is a rural area – the district covers eight villages from Reichenbach-Steegen in the West to Rodenbach in the East. Weilerbach´s aim is to become a zero emission village by achieving CO2 neutrality by 2015.

Tulln, a town of 14,000 people at the river Danube in Lower Austria, has an excellent basis for its participation in CONCERTO. It has worked for a number of years on becoming more sustainable and on reducing its greenhouse gas emissions. Tulln installed a biomass-based district heating system and the municipality supports private citizens who want to install solar collectors. In addition, much of its electricity is generated by hydropower. Tulln aims to consolidate and build on this process.

Zaragoza is together with Lyon one of the 2 cities involved in the RENAISSANCE project, part of the Concerto Initiative. The project involves El Picarral, an existing community in need of building refurbishment and urban re-generation, and Valdespartera, a new community. Both are linked by the integrated political commitment of all actors and a common set of performance criteria.

Grand Lyon Urban Community is the 2nd conurbation of France and is located in the heart of the Rhone-Alps Region, which is at the peak of sustainable energy development in France. The Grand Lyon demonstrates through its direct participation in this project its will to make environment-friendly urban and building design a major axis of its commitment toward sustainable development.

Zagorje is showing that locally available, low-valued renewable energy resources can be capitalized. In Zagorje´s case, it is water from abandoned mines. A system is being put in place that will use geothermal energy from mine-water to heat a youth centre and a primary school. The water has a temperature of around 33 to 34 degrees Celsius and will also be the source of cooling energy that is provided for the commercial buildings and a planned swimming pool.

Through its participation in the CONCERTO project, the Dutch city of Heerlen uses heat energy stored in old mineshafts for the heating and cooling of buildings.

The last miner left the mines in Heerlen in 1976. Since then the former mineshafts have been filled with geothermally heated ground water, which has a different temperature at different depths and can therefore be used for both - heating and cooling.
