Multicriteria analysis : identifying benefit optimized energy efficiency measures in public buildings

  • 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 inThe 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".show moreshow less
