3 Our projects in Speyer Kaserne Normand District heating / wood chips / solar heating Kaserne Normand Retrofit Schlachthof Solar district heating Yachthafen Speyer Heat pump using waste heat from sewer Seite 3

4 Innovative Energy Projects in Speyer PV-systems solar heating use of waste heat district heating geothermal energy many individual projects / no "masterplan" CHP combined heat and power generation Seite 4

5 Energy strategy for the city of Speyer Energy and climate protection guidelines (City council) voluntary commitment to reduce carbon emissions by - reducing energy consumption - increasing use of renewable energy Climate protection strategy work packages: - analysing actual situation (energy balance) - finding potentials for energy savings - defining a package of measures Seite 5

6 Financing.. a support programme of the development of "climate protection strategies" financing a "climate manager" implementation of energy saving technologies Seite 6
