Die Umweltauswirkungen von Teil-, Miet- oder Tauschangeboten aus dem Bereich der Sharing Economy werden zumeist aus einer Nachhaltigkeitsperspektive betrachtet und dementsprechend mit einer Verminderung des Ressourcenverbrauchs sowie einer gesteigerten Ressourceneffizienz verbunden. Handelt es sich bei Sharing Economy tatsächlich um eine ressourcenschonende, energieeffiziente und für den "Massenmarkt" geeignete Konsumalternative oder haben wir es vielmehr mit einer kurzzeitigen Nischeninnovation einzelner Lifestyle-Communities zu tun?
Zahlreiche Untersuchungen prognostizieren einen erheblichen Anstieg des globalen Ressourcenverbrauchs in den nächsten Jahrzehnten, wenn es nicht zu grundlegenden Veränderungen der Wirtschaftsweise kommt. Gegensteuern ist möglich durch politische Maßnahmen und einem Umdenken sowohl in der Produkt-Dienstleistungs-Entwicklung, bei der Gestaltung von Wertschöpfungsketten als auch im Konsumverhalten. Das Projekt BilRess identifiziert und entwickelt Angebote für alle Bildungsbereiche zum Thema Ressourcenschonung und Ressourceneffizienz.
Die in diesem Artikel vorgenommene Bestandsaufnahme der verschiedenen Bildungsangebote und die Analyse der Bildungsbereiche zeigt eine Vielzahl von Verbesserungsmöglichkeiten und Anknüpfungspunkte zur Implementierung von Ressourcenschonung und -effizienz in die unterschiedlichen Bildungsbereiche. Dabei wird immer wieder deutlich, dass die einzelnen Bildungsbereiche nicht isoliert betrachtet werden können. Die herausgearbeiteten Handlungsempfehlungen fließen in die Erstellung einer "Roadmap Ressourcenbildung" ein.
A continuing trend of global urbanization leads to a geographical concentration of population and social activities that causes a regional compression of concomitant resource and energy consumption. This paper argues that a Sustainable Living Lab infrastructure (SusLab) in urban areas facilitates a systematic integration of user's consideration in the design and development of Product-Service Systems (PSS) that enables changes of daily routines in favor of urban wealth development and conservation of ecosystem services. The authors build on the Sustainable Consumption and Production (SCP) Model of the Wuppertal Institute that provides a theoretical framework of sociotechnical rearrangements towards urban sustainability transition. Therefore, a reconfiguration of social practices and PSS in a desired direction according to social, ecological and economic concerns is reconsidered on the micro level in line with efficiency, consistency, and sufficiency strategies. The authors introduce an assessment framework for urban sustainable development and illustrate multifarious concepts of PSS that are aiming to decouple wealth development from resource and energy consumption in urban areas.
Many technical solutions have been developed to enhance the energy efficiency in buildings. However, the actual effectiveness and sustainability of these solutions often do not correspond to expectations because of the missing perspective of design, user's real needs, and unconsidered negative side effects of their use (rebounds). With the aim to help address these challenges, this paper presents results of a longitudinal living lab study and proposes a user-centered building management system (UC-BMS) as a prototype for office buildings. Based on mixed methods, UC-BMS was co-developed, tested, and evaluated in Germany in up to six office buildings, 85 offices, and within two heating periods. The results demonstrate that such user-oriented approach can save up to 20% of energy while maintaining or even improving comfort and work productivity. The findings show three main areas of intervention and elements of UC-BMS: (1) How interactive design and feedback systems (e.g., air quality) can stimulate ventilation practices and energy efficiency in offices and (2) supporting heating system optimization e.g., by better understanding office behavior. (3) Finally, an office comfort survey was conducted to enable communication between facility management and office users and thus limiting complaints and adapting the heating system towards actual office user needs.
It is widely accepted that environmental awareness is essential, yet does not inevitably lead to responsible use of resources. Additional factors on the individual level include the meaning constructed by the term "resources" and the individual and social norms that influence the relevant behavior. Current didactic concepts do not take into account such aspects. Therefore, this article uses a didactic-psychological approach for designing an educational concept for raising awareness for a responsible use of natural resources. Combining insights of environmental psychology and of constructivist didactics, a general principal of "norm-oriented interpretation learning" is outlined to enrich the didactic debate on responsible and efficient resource use. Based on the presentation of a qualifying module for resource efficiency consultants as a practical example of resource education, a new didactical approach, namely "open-didactic exploration" (short form: ODE) is introduced. The article discusses the theory-based elements of ODE and illustrates a step by step process for designing educational materials. This adds to the theoretical debate about a didactic design for resource oriented education. Furthermore, this method can be directly used by practitioners developing education and training material (e.g., teachers, trainers in vocational education). The Wuppertal Institute developed and applied this method in numerous projects. The conclusion and outlook discusses future expectations and scope of the introduced ODE method as a contribution to foster "norm-oriented interpretation learning", suggesting perspectives for further development.
Die explosive Verbreitung des Corona-Virus über die Welt brachte ein Realexperiment globaler Dimension mit offenem Ausgang hervor. Gesellschaften formieren sich, kosmopolitisch verschränkt, als Hygienegesellschaften. Zwischen striktem Lockdown und minimaler Begrenzung gehen sie je eigene experimentelle Wege. Dabei wird der Raum des Experimentellen bisher eher defensiv gestaltet, was in der Konsequenz zur Begrenzung experimenteller Räume sowie zur schleichenden Delegitimierung von Kontrollpolitiken der Pandemie führt. Die These dieses Beitrags lautet, dass solche Legitimationsprobleme umso eher gelöst werden können, je eher Strukturen resilienten Experimentierens entworfen und institutionalisiert werden. Ein wichtiges Ergebnis der Überlegungen ist, dass die resiliente Gestaltung experimenteller Räume zur Bewältigung solchen Krisengeschehens nur gelingen kann, wenn neben top-down verordneten Kontrollen sich eine bottom-up-Kultur sozialen Experimentierens entfalten kann. Dies setzt auf Seiten der Zivilgesellschaft ebenso wie von staatlicher Seite die Fähigkeit und den Willen zu Partizipation und Kooperation voraus. Entsprechende Ansatzpunkte werden dafür identifiziert.
A key factor to energy-efficiency of heating in buildings is the behavior of households, in particular how they ventilate rooms. Energy demand can be reduced by behavioral change; devices can support this by giving feedback to consumers on their behavior. One such feedback device, called the "CO2 meter", shows indoor air-quality in the colors of a traffic light to motivate so called "shock ventilation", which is energy-efficient ventilation behavior. The following effects of the "CO2 meter" are analyzed: (1) the effect of the device on ventilation behavior within households, (2) the diffusion of "CO2 meter" to other households, and (3) the diffusion of changed behavior to households that do not adopt a "CO2 meter". An agent-based model of these processes for the city of Bottrop (Germany) was developed using a variety of data sources. The model shows that the "CO2 meter" would increase adoption of energy-efficient ventilation by c. 12% and reduce heating demand by c. 1% within 15 years. Technology diffusion was found to explain at least c. 54% of the estimated energy savings; behavior diffusion explains up to 46%. These findings indicate that the "CO2 meter" is an interesting low-cost solution to increase the energy-efficiency in residential heating.
Resource efficiency in production and technological innovations are inadequate for considerably reducing the current use of natural resources. Both social innovations and a complementary and equally valued strategy of sustainable consumption are required: goods must be used longer, and services that support collaborative consumption (CC) patterns must be extended. "Using rather than owning" strategies, such as product sharing, have the potential to conserve resources. Based on the results of different German studies, this article highlights the resource-saving potentials of CC patterns and recommendations proposed for policies and further research questions. The purpose of this paper is to show that a general resource-saving potential can be realized by "use rather than own" schemes, depending on the application field and the framework for implementation. CC is suitable for making a positive contribution to achieving the Factor 10 target by playing an important role in changing consumer patterns.
Social innovations, which transform resource intensive routines and practices into low-resource ones, combined with socio-technically designed transition paths, which are created around sustainability and environmental criteria, are milestones for implementation and diffusion of SCP (Sustainable Consumption and Production). This paper analyses such processes based on eight key components in order to evaluate and explain transformation and transition towards a sustainable lifestyle. Actors on all levels of society are included in this approach, creating a whole framework. Global megatrends, such as climate change, demographic change or resource scarcity will be put into relation with current policies and production trends, which play an important role for the development of transition pathways and future scenarios. This will enable us to work out guidelines and ideas on how to create a more sustainable society specifically.
