Bad Hersfeld is a small city with about 30.000 inhabitants situated in the middle of Germany. Climate Protection has been on the political agenda in Bad Hersfeld since quite a while. In 1997 the Wuppertal Institute elaborated a first energy and CO2 balance for the city, which was updated in 2007. With the compilation of the CO2 balance it was shown that the emissions in Bad Hersfeld almost stayed at a constant level between 1997 and 2006.
The result was sobering for the local authority. Although some single measures had been implemented, there was no improvement of the CO2-balance.
It was concluded that a successful climate protection strategy needs a comprehensive concept comprising all sectors and a periodic monitoring. Bad Hersfeld commissioned the Wuppertal Institute to develop feasible measures to reduce the CO2 emissions drastically and instruments to overcome existing barriers. In a close cooperation with the City Council and the local municipal utility a climate protection concept was compiled that is rather ambitious for a city of this size.
In consideration of the regional peculiarities12 concrete measures and 7 accompanying measures build the core of the concept with a main focus on energy efficiency (final energy), combined heat and power (CHP) and renewable energies. Another important part of the concept is a municipal support programme to develop the endogenous efficiency potentials and renewable energies in the region. Further to these planning instruments, information and networking activities are compiled as well as a variety of suggestions for a climate protection marketing (Wagner 2008).
Some of these measures that were developed in an iterative and cooperative process between the responsible actors in Bad Hersfeld and the Wuppertal Institute are transferable to other cities and towns. The impeding factors in Bad Hersfeld like the user-investor dilemma, the low capital of small housing associations or the large stock of listed historical buildings, are typical for cities of this size.
The general conditions for local authorities in Germany have changed fundamentally during the last decades. Not only do municipalities compete with each other for employment, prestige and competitive advantages, they also face increasingly higher demands by their citizens, for instance in the area of climate protection.
Therefore, every municipality has to consider various economic, social and ecological determinants in its decision-making processes. With respect to public buildings, an economically-oriented cost-benefit-analysis alone is not adequate due to a municipality's role as "consumer and role model". To identify measures with a broader benefit, a multicriteria analysis (MCA) has been used to analyze energy efficiency measures in public buildings for the city of Dortmund.
For several years Dortmund has committed itself to implement energy efficiency measures and improve the energy performance of its building stock. Nevertheless, a benchmark analysis still shows a high energy saving potential that cannot be tapped with the existing measures and instruments. Therefore, a package of measures has been developed in close cooperation with the city of Dortmund, ranging broadly from measures of energetic retrofitting and green IT to behavioral change of building occupants.
In the MCA these measures have been assessed according to ten different criteria such as innovativeness, cost effectiveness, external costs, CO2 reduction potential, local value or effort of implementation. Three different scenarios ("City as Role Model", "City as Homo Oeconomicus", "City as Climate Protector") show different municipal perspectives.
The analysis has shown that the greatest benefit for municipalities, regardless of the municipal perspective, is yielded by measures such as voluntarily enhanced minimum standards for new or for energetic retrofitting of public buildings, the procurement of energy-efficient office equipment, the expansion of heat generation from renewable energies and the usage of private capital in participatory projects like "Solar&Save".
Klimaschutzkonzept für den Kreis Nordfriesland : Vertiefungsband ; die Energie- und CO2-Bilanz
(2011)
Belgien hat einen nationalen Energieeffizienz Aktionsplan (National Energy Efficiency Action Plan, NEEAP), der ein Energiesparziel von 27,5 TWh für das Jahr 2016 in Gebäuden, Verkehr und Kleingewerbe setzt. Rund 62 % der geplanten Energieeinsparungen sollen demnach in Flandern, 30 % in der Wallonie und 8 % in Brüssel-Hauptstadt erreicht werden. Zur Erreichung der Ziele soll jede Region eigene Anreize und Vorschriften in Bezug auf Energieeffizienz entwickeln. Das Energieleitbild ist somit in die Zielvorgaben der Wallonischen Region eingebunden.
Das langfristige Ziel der DG geht über diese Zielvorgabe hinaus und hat zum Kern die bilanziell "energieautarke DG". Dazu bedarf es einer auf Dauer angelegten und breit gefächerten Energieplanung mit konkreten und messbaren Teiletappen und -zielen. Die Erarbeitung eines regionalen Energieleitbildes stellt daher die Basis aller weiteren Schritte und Maßnahmen dar.
Vor diesem Hintergrund hat die DG das Wuppertal Institut im Rahmen einer öffentlichen Ausschreibung beauftragt, ein Energieleitbild für die Region zu erstellen. Dieses Energieleitbild beinhaltet folgende Elemente:
Bestandsaufnahme: Hier erfolgt eine Bewertung der energetischen Ist-Situation in der DG. Die Datenerhebung erfolgte in enger Kooperation mit dem Auftraggeber.
Potenzialanalyse: In der Potenzialanalyse werden die theoretischen Einsparpotenziale und die Möglichkeiten zur verstärkten Nutzung erneuerbarer Energieträger dargestellt.
Vision: Hier wird ein Bild einer positiven Entwicklung der DG anhand eines narrativen Szenarios entworfen.
Umsetzungs- und Fahrplan: Diese Pläne beinhalten Vorschläge für Maßnahmen und Aktionen zum Erreichen der Zielsetzungen, sowie mögliche Umsetzungszeiten.
Finanzierungsplan: Der Finanzierungsplan beinhaltet zahlreiche Vorschläge zur Finanzierung.
