    Description: Purpose To accomplish the national and international climate goals, building renovation and optimisation of their energy and resource efficiency are essential. Thus, reliable information on the building stock (BS) is necessary. Most previous building typologies are focussing on residential buildings and the operational phase. This paper shows the development of a methodology for generating non-residential building (NRB) typologies for life cycle inventory analysis (LCI) of building constructions. Hereby, archetypes of office, administration and department (OAD) buildings are developed, exemplarily for the German NRB stock. The methodology can further be utilised for quantity surveying of urban material stocks, related recycling scenarios and waste management. Furthermore, the exemplarily generated archetypes provide necessary information for the estimation of realistic refurbishment scenarios. Methods Approaches for the development of NRB archetypes, the descriptions of associated building materials and the LCI of BS were analysed and integrated into a methodology. It provides a clear path on the classification in building usage categories and determination of relevant building parameters for conducting LCI studies. Its aim is the creation of NRB typologies, presenting construction materials and building geometry in a useful way for life-cycle assessments (LCA). To demonstrate the methodology’s usability, it is applied to a case study with the sample of 161 OAD buildings, provided by the German NRB database ENOB:dataNWG. In combination with relevant literature on BS archetypes and materials, a sample OAD building typology has been created. Results and discussion Minimum data requirements for conducting simplified LCI calculation of BSs were identified by analysing existing LCA methods, like the German BNB system. Important clusters for developing NRB archetypes were determined: building usage category, building construction types and building age. These data gaps between required information for simplified LCA studies and available information in ENOB:dataNWG were identified, and solutions for closing these data gaps were proposed and tested. Since building archetypes must reflect the overall BS, uncertainties were discussed. The ENOB:dataNWG database was not completed at the time this paper was written, so comprehensive uncertainty analyses are important next steps. Conclusions This methodology development forms the groundwork for creating LCI building typologies for simplified LCA studies. It shows practically how to deal with a BS database and illustrates which typical values can be chosen for closing data gaps. The methodology was tested on an exemplary sample of OAD buildings. Based on this case study, the methodology concept was proven useful for the generation of a NRB typology.

    Description: European coal mining regions face massive transformational challenges. The necessity of climate protection only intensifies a trend, prevalent in all of Europe: coal mining has been losing its economic importance over the last decades. Fewer and fewer people are employed in the sector. Coal regions face the challenge of how to facilitate a just transition, and which perspectives to develop for a future beyond coal. Against this background this study analyses the current situation in four key European coal mining regions, namely: Aragon in Spain, Lusatia in Germany, Silesia in Poland and Western Macedonia in Greece. The study provides a brief summary of the regions' socio-economic structure, including the respective role of coal mining. An assessment of how existing European structural instruments, specifically the European Structural and Investment Funds (the ESI Funds) are utilised in the region, forms the core of the study.

    Description: Der Gebäudebereich steht nicht nur aufgrund seiner Umweltwirkungen vor großen Herausforderungen. Bei der Einhaltung der Klima- und Nachhaltigkeitsziele spielen auch die mit langen Lebens- und Nutzungsdauern von Gebäuden einhergehenden Investitionszyklen eine entscheidende Rolle. Politische und planerische Maßnahmen werden bislang hauptsächlich im Rahmen von Effizienz- und Konsistenzstrategien entwickelt und umgesetzt, um Umweltwirkungen zu minimieren. Die Suffizienzstrategie erfährt im Vergleich dazu eine deutlich geringere Aufmerksamkeit. Ziel dieses Vorhabens ist es deshalb, Suffizienz für den Gebäudebereich zu definieren, geeignete technische und organisatorische Ansätze zu ihrer Unterstützung zu identifizieren sowie Vorschläge zu ihrer Verankerung in politischen und rechtlichen Rahmenbedingungen und Instrumenten zu erarbeiten und exemplarisch darzustellen.

    Description: Seit Einführung der ersten Wärmeschutzverordnung in den 1970er Jahren als Antwort auf die Ölkrise sind die energetischen Anforderungen an Gebäude kontinuierlich gestiegen. Heute werden sie im Gebäudeenergiegesetz (GEG) geregelt, das aktuell erneut novelliert wird. Trotz dieser kontinuierlichen Verschärfungen der Anforderungen ist der Endenergiebedarf von Wohngebäuden in Deutschland in den letzten Jahrzehnten kaum gesunken. Ein wesentlicher Grund hierfür ist die ebenso kontinuierlich steigende Wohnfläche pro Person.

    Description: Since the introduction of Germany's first Thermal Insulation Ordinance in the 1970s in response to the oil crisis, requirements for the energy performance of buildings have consistently increased. Today, these are ruled by the German Building Energy Act, which is currently being amended. Despite this continuous tightening of regulations, the energy consumption in German housing has hardly decreased. The continuous increase in residential space per person is a significant reason for this.

    Description: Der hier vorliegende Klimaschutz-Aktionsplan 2030 für die Stadt Mannheim beschreibt Maßnahmen und Reduktionspfade für eine Minderung der Treibhausgasemissionen auf Mannheimer Stadtgebiet zur Erreichung der Klimaneutralität im Jahr 2030. Die Basis hierfür bildet die Energie- und CO2-Bilanz aus dem Jahr 2020. In einem ersten Schritt wurden mit dem wissenschaftlichen Begleitkreis mögliche Reduktionspfade in den verschiedenen Sektoren und eine Definition für den Begriff der Klimaneutralität diskutiert. Mit dem Lenkungskreis wurden im nächsten Schritt acht Handlungsfelder festgelegt, für die in einzelnen Strategiegruppen die Maßnahmen entwickelt wurden. Weitere Vorschläge kamen aus der begleitenden öffentlichen Beteiligung. In diesem breit angelegten Beteiligungsprozess sind letztlich 81 Maßnahmen in acht thematischen Handlungsfeldern entstanden, von denen 34 als Maßnahmen von besonderer Priorität definiert wurden.
