Neun Doktorandinnen und Doktoranden und sieben Professorinnen und Professoren waren in das Kolleg eingebunden, die sich in verschiedenen Forschungsthemen und -bereichen mit dem Energiebewusstsein in der Stadt- und Regionalplanung beschäftigten. Die vorliegende Arbeit beschäftigt sich mit dem Thema der Post-Oil-City und der Frage, wie bisher vom Autoverkehr beanspruchte Räume in Zukunft für die städtische Innenentwicklung genutzt werden können. Dabei wird die Identifizierung dieser Räume durch die Verwendung und neuartige Kombination von Methoden ermöglicht. Raum, seine Funktion, Nutzung und Gestaltung sind eng mit dem Thema der energiebewussten und nachhaltigen Stadt verwoben. Global gesehen ist der Verkehr für 25% des zugeführten Energieverbrauchs verantwortlich (Sumantran et al., 2017, S. 49). Das ist mehr als der gesamte Energieverbrau...

Nine doctoral students and seven professors were involved in the program. The present work deals with the topic of the post-oil city and the question of how urban spaces previously occupied by car traffic can be used for urban inward development in the future. The identification of these spaces is thereby made feasible through the novel combination and application of several methods. Space, its function, use, and design are closely interwoven with the topic of the energy-consciousness and sustainable city.From a global perspective, transport is responsible for 25% of the energy consumed (Sumantran et al., 2017, p. 49). This is more than the total energy consumptio...

Ziel ist es, Optimierungsstrategien für Führungsformen und Knotenpunkte durch Erfassung des gegenwärtigen Zustandes und Simulationen von Variationen in Living Labs zu entwickeln. Der Ansatz verfolgt Methoden im realen und virtuellen Raum. Die aus den Erkenntnissen entwickelten Werkzeuge und Empfehlungen für eine moderne Stadt- und Verkehrsplanung sollen helfen, durch gute Infrastruktur die Attraktivität des Zu-Fuß-Gehens und Radfahrens zu steigern, speziell vor dem Fokus der Reduktion von Stress und Konflikten. Oftmals bilden diese eben ein persistierendes Hemmnis in der Gruppe der unentschlossenen Radfahrerinnen, Radfah...

While there is consensus about its necessity, politicians, administrations, and citizens have to deal with the effects of infrastructure construction on a local level. The success of participation depends on several factors, to some of which digital tools (e.g., online communication or Virtual Reality visualization) can contribute. Decisions can be improved by reducing the complexity of technical knowledge, simplifying data processing, picturing results in an intuitive way, and making participation more attractive. This chapter focuses on the potential of visualization tools. It describes and evaluates two case studies from the perspective of the executing organization on the one hand and the involved citizens on the other hand: the Forbach Pumped-storage Power Plant and the Traffic development in Herrenberg. However, digital instruments cannot obviate the need for a tailor-made conc...

In general, cities are complex systems being a ``heterogeneous mosaic'' of a variety of cultures and functions, characterised by diverging perceptions and interests (ibid). The juxtaposed perceptions and interests in relation to ongoing spatial processes of change create a particularly complex situation. Thus, for planning processes we are in need of approaches that are able to cope not only with the urban complexity but also allow for participatory processes to empower citizens. This paper presents the approach of using Digital Twins in virtual reality (VR) for civic engagement in urban planning, enriched with quantitative and qualitative empirical data as one promising approach to tackle not only the complexity of cities but also involve citizens in the planning process.

Thus we are creating post oil scenarios using Paris as a case study to simulate the transition from fossil fuels to renewable energy as well as reduction of path distances (“city of short distances”) in order to find out more about how urban planning can influence developments incorporating the idea of reducing primary energy demand and emissions. These scenarios include actual urban development and master plans as well as detailed test planning for certain neighbourhoods. Based on these scenarios we analyse the effects of urban planning on energy and environment by developing a combination of methods for creating a decision and planning support tool.

Herein used approach enables to empower citizens in a novel way using digital, emerging technologies. Until now Digital Twins have been mainly used in the field of engineering and their implementation for towns only have been recently discussed (Batty, 2018). A Digital Twin is a digital representation enabling comprehensive data exchange and can contain models, simulations and algorithms describing their counterpart and its features and behaviour in the real world (Kuhn, 2017). We present the development and test application of a Digital Twin in Virtual Reality for the 30,000 people town of Herrenberg in Germany. Our modelling approach includes a mixed method with 3D models, simulations, 3D mapping and computational analysis with space syntax as a socio-spatial approach. For citizen participation the Digital Twin was embedded in the collaborative visualization and simulation environment "COVISE". The Digital Twin for Herrenberg was exposed to approximately 1,000 citizens using a mobile and stationary Virtual Reality environment. For verification and consolidation, a survey was carried out. The results demonstrated that the use of this method and technology could be very supportive in participatory and collaborative processes. A criticism of Digital Twins is that they abstract only a limited set of variables and processes and rarely includes any of the processes that determine how the city works in terms of its social and economic functions (Batty, 2018). We therefore conclude the paper with a discussion of the presented results and further research direction how to include more social and economic functions using a synthetic population model. Digital twins for towns will help urban planners and designers to understand and inform about impacts of intended urban change with citizens having a voice and the opportunity to influence public decisions for smart, sustainable cities. This democratic decision-making process empowers people to reach public consensus.

They are also characterized by diverging perceptions and interests of citizens and stakeholders.

Connected to the field of smart cities and citizens, we present in this paper, the prototype of an urban digital twin for the 30,000-people town of Herrenberg in Germany. Urban digital twins are sophisticated data models allowing for collaborative processes. The herein presented prototype comprises (1) a 3D model of the built environment, (2) a street network model using the theory and method of space syntax, (3) an urban mobility simulation, (4) a wind flow simulation, and (5) a number of empirical quantitative and qualitative data using volunteered geogra...
