Stadt Ulm – Toprunner in the South § Ulm is a university town in Baden-Württemberg at the river Danube, located south-east of Schwäbischen Alb. § Ulm has 120. 000 Inhabitants, the central town about 100. 000 inhabitants. § The tower of the cathedral is with 161, 53 m one of the highest in the world. § A famous son of the town is Albert Einstein, born hier in 1879 Klimastadt Ulm – dank Biomasse / D.

Stadt Ulm – Aktiv Passiv § Science Park II does not only host global companies such as Daimler, Nokia, or Siemens, but also the worldwide biggest passiveenergy office building § On the occasion of the World Exhibition EXPO 2000 the project „sun fields“ was constructed in Ulm. With 110 single family buildings it was at that time the biggest passive -house settlement worldwide. In the meantime, 50 single houses have been added. Further passivehouse settlements are in planning. Klimastadt Ulm – dank Biomasse / D. Danks / 05. 06. 2008
Ulm – City in a Climate Alliance § In 1993 Ulm has joined the Rio Climate Alliance. The city has committed to reducing its CO 2 emissions, serving as indicator for overall environmental impact, by 50% compared to 1987 levels. § Like other cities, the city of Ulm is unlikely to reach this target. Generally, despite a great number of activities, all efforts are levelled out by steadily increasing traffic volumes. § The only hope of the city lies now with our company Fernwärme Ulm Gmb. H. Thanks to our district heating system, based almost entirely on CHP, extensive use of surplus heat and use of CO 2 -neutral fuels, significant progress allows to demonstrate significant progress and success.

FUG - Guidelines § The best energy is the one that is not being used. § The remaining energy should be used as efficiently and climate-friendly as possible. § Independence from imported energies. Klimastadt Ulm – dank Biomasse / D. Danks / 05. 06. 2008
Anteil der regenerativen Energien § Germany 2004 Heat supply 4, 2 % Electricity supply 9, 3 % § Germany 2020 (declared intentions) Heat and electricity supply 20 % each § FUG 2005 50% share of renewable energies, incl. Energy from the MHKW Donautal § Outlook FUG from 2011 80% share of renewable energies Klimastadt Ulm – dank Biomasse / D. Danks / 05. 06. 2008

Intake of surplus heat FUG is open to concepts from private investores: § § § Since 1996 FUG buys surplus heat from saw dust from a big wood manufacturing plant. § In 2 month, a 1, 7 km preinsulated pipe (under construction) will connect a a biogas plant in Gögglingen that is twice that size. § A further biogas plant is in the authorisation process. Since 1997 FUG buys surplus heat from a waste incineration plant Since 2006 surplus heat from a private biogas plant with a capacity of 500 k. W is being fed into the network Wiblingen eingespeist.
