Klimastadt Ulm – dank Biomasse / D. Danks / 05.06.2008
Ulm is a university town in Baden-Württemberg at the river Danube, located south-east of Schwäbischen Alb.
Ulm has120.000 Inhabitants, the central town about 100.000 inhabitants.
The tower of the cathedral is with161,53 m one of the highest in the world.
A famous son of the town is Albert Einstein, born hier in 1879
Stadt Ulm – Toprunner in the South

Science Park II does not only host global companies such as Daimler, Nokia, or Siemens, but also the worldwide biggest passive-energy office building
On the occasion of the World Exhibition EXPO 2000 the project „sun fields“ was constructed in Ulm. With110 single family buildings it was at that time the biggest passive-house settlement worldwide. In the meantime, 50 single houses have been added. Further passive-house settlements are in planning.

Ulm – City in a Climate Alliance
In 1993 Ulm has joined the Rio Climate Alliance. The city has committed to reducing its CO2 emissions, serving as indicator for overall environmental impact, by 50% compared to 1987 levels.
The only hope of the city lies now with our company Fernwärme Ulm GmbH. Thanks to our district heating system, based almost entirely on CHP, extensive use of surplus heat and use of CO2-neutral fuels, significant progress allows to demonstrate significant progress and success.
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.

Die Fernwärme Ulm GmbH
FUG is THE heat supplier in Ulm:
ca. 45 % of the entire heat demand of the city is being produced by FUG.
Shareholders of FUG are:- Energie Baden-Württemberg AG (EnBW)- Stadtwerke Ulm/Neu-Ulm GmbH (SWU) Holding 50% each
FUG employs approx. 200 people
District heat supply in Ulm since 1950
The Technical Director FUG, Mr. Dieter Danks, has just been reelected for the 6th time by all environmental associations as chairman of the Local Agenda 21 in Ulm

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.

Intake of surplus heat
FUG is open to concepts from private investores:
Since1996 FUG buys surplus heat from saw dust from a big wood manufacturing plant. 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 kW is being
fed into the network Wiblingen eingespeist . 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.

Konsequentes Handeln nach den FUG - Leitlinien
The best energy is the one not being used
Reservation of construction areas exclusively for passive houses
Identification of refurbishment areas, going hand in hand with refurbishment of existing building stock
Optimisation of district heating grid– conversion from steam
Independence from imported energies Operation of planst with Biomass, Waste and (remaining)
coal Use of surplus heat
Supply remaining heat as efficient and environmentally and climate friendly as possible
