Item Digital Twin, Microclimate Simulations, and Dynamic Visualization of the Central Library of TU Dortmund University(2024-03-19) Kirsten, Jens; Pham, Nhat Anh; Range, Leonard-Louis; Schröer, Kai; Wickert, Konstantin; Winter, Nadine; Thinh, Nguyen Xuan; Latko, JasminThe term Digital Twin essentially describes the creation of a virtual replica and its net- working with its real physical counterpart. In the context of the digitization efforts of municipalities, the term is now increasingly being used in the context of spatial planning. There, great potential can be assumed, especially against the backdrop of the advancing climate change, for example with regard to the simulation and visualization of climate impacts in urban spaces. Even if this potential seems to be clearly outlined, at least on paper, it is still unclear how this potential can be leveraged in practice. Also unclear is the positive contribution that can be expected from the high spatial detail of digital building models to the accuracy of often coarsely modeled climate simulations. Therefore, this study aims to identify the application potential of Digital Twins of buildings in the context of spatial planning by means of a literature review and to iden- tify possibilities of combining the process of Digital Twin creation with microclimate simulations in an explorative case study using the example of the Central University Li- brary of the TU Dortmund. One focus of the work is the dynamic visualization of the Digital Twin and the climate simulation results. To this end, a unified conceptual under- standing of Digital Twins will be established and practical examples of how the term is understood and its potential applications will be presented. Subsequently, the work pro- cess from the creation of a laser scan-based, detailed 3D building model to the execution of various microclimate simulations and dynamic visualization possibilities of the Digital Twin is presented. The discussion of practical examples of Digital Twins in spatial planning showed that their practical application is still in an early stage. It also became clear that the under- standing of the term Digital Twin in practice and research often differs and that in many practical cases, including the results of this work, the term Digital Shadow should rather be used. As for the microclimate simulations, the effects of three variations of the model- ing on the simulation results could be illuminated. According to this, the size of the study area, but also the spatial resolution of the whole model seem to have a low influence on the results, while the influence of the LoD could not be clearly clarified. Finally, several tools for dynamic visualization of the results could be successfully applied in the context of the work. However, it became clear that their application requires certain technical knowledge (e.g. programming languages), which in turn may deter many spatial planners from using them.Item Development and use of Digital Twins for campuses in Dortmund and Bến Cát for climate adaptation measures(2023-07-02) Böse, Lena; Czech, Ole; Eismann, Flemming; Hohle, Christian; Kanelias, Jan; Maiwald, Lea; Michaelis-Braun, Raphael; Mintzlaff, Laura; Quante, Beeke; Schumacher, Ben Luca; Schwarz, Yannic; Sommer, Alina; Wiegand, Sophie Christine; Wissen, Marit; Thinh, Nguyen Xuan; Karakus, SinanClimate Change is the leading cause for the warming of the atmosphere, land, and oceans. As a result, urban areas are particularly affected by the urban heat island phenomenon, which has a significant negative impact on human health, energy consumption and everyday life. To mitigate the effects on the environment and residents, researching new technologies such as Digital Twins in Smart Cities can be crucial. This research aims to evaluate the effectiveness of the usage of Digital Twins for developing climate adaptation measures to mitigate urban heat island effects. A key element of this evaluation is analyzing the potentials and limitations of the Digital Twin technology, emphasizing the creation process of a Digital Twin as well as the application and its usage. A Digital Twin is created for a building on the campus of the TU Dortmund University and the Vietnamese- German University. The methods of laser scanning and 3D modeling serve as a foundation for the creation process of the Digital Twins. To analyze the effect of climate adaptation measures on built environment, microclimatic simulations are conducted. The results of the research including the 3D model and the microclimatic simulations are visualized in a geoinformation map. The evaluation process revealed multiple challenges in the development process and the usage of the Digital Twin technology. The main areas for improvement were identified in terms of data availability, data interoperability, and mesh creation. However, it is important to note that Digital Twin appears to have a significant potential for future urban development.Item Identifizierung geeigneter Flächen für Hochwasserrückhaltebecken und Versiegelungsverbotszonen: Eine GIS-basierte Analyse im Ahrtal(2022-08-01) Eickelmann, Johanna; Engels, Sofie; Franzmann, Hannah; Gayko, Noemi; Hijazi, Alaa; Hölzner, Robin; Hövel, Simon; Kneilmann, Maja; Knipper, Tim; Niehues, Marc; Paßlick, Oskar; Pilarczyk, Sabrina; Schlott, Mira; Schmidt, Melanie; Schultze-Schlutius, Theo; Wrase, Till; Thinh, Nguyen Xuan; Schaefer, Mathias; Kruse, PhilipDie folgenschwere Hochwasserkatastrophe im Juli 2021 verdeutlicht die Notwendigkeit zur Verbesserung der Hochwasser- und Überflutungsvorsorge in den betroffenen Regionen des Ahrtals. Ziel der Arbeit ist es, unter Verwendung einer multikriteriellen Bewertungsmethodik auf regionaler Maßstabsebene, potentielle Standorte für Hochwasserrückhaltebecken und Versiegelungsverbotszonen zu identifizieren. Durch eine Erhöhung der Wasserspeicherkapazitäten in der Landschaft und eine Reduzierung der weiteren Versiegelung in hochwassergefährdeten Bereichen sollen bei zukünftigen Starkregenereignissen die Schäden in den betroffenen Regionen des Ahrtals minimiert werden. Die angewandte Methodik stützt sich auf kriterien- und indikatorenbasierte Analysen mit einem Geo-Informationssystem (GIS) und einer mathematischen Optimierung mittels Compromise Programming (CP). Dies dient der transparenten und nachvollziehbaren Kompromisslösung verschiedener Belange. Die Gewichtungen der einzelnen gewählten Kriterien und Indikatoren basieren auf Erkenntnissen einer Feldforschung im März 2022 und auf dem Fachwissen von Expert:innen unter Verwendung der Gewichtungsmethode Analytic Hierarchy Process (AHP). Im Zuge der Feldforschung konnten die ermittelten Flächen hinreichend überprüft werden. Insgesamt konnten zwölf Standorte für Hochwasserrückhaltebecken, welche eine Fläche von 150 ha aufweisen, sowie acht potentielle Versiegelungsverbotszonen mit einer Fläche von 57,78 ha identifiziert werden. Die Diskussion zu den Analyseergebnissen und den ermittelten Flächen kann beispielsweise als Abwägungsgrundlage bei der Verbesserung der Hochwasservorsorge dienen. Des Weiteren stellt die konzipierte Bewertungsmethodik ein reproduzierbares Schema für die Standortsuche der gewählten Hochwasser- und Starkregenvorsorgemaßnahmen in vergleichbaren Regionen dar.Item Studentische Wohnbedürfnisse und Möglichkeiten ihrer Realisierung in der Stadt Dortmund(2018) Bertram, Maie; Gastmeister, Robin; Kops, Alexander; Lübbers, Johanna; Meissner, Stephanie; Rettmann, Jule; Schellenbach, Felix; Siemensmeyer, Nora; Volmer, Carlin; Schulte, JanItem Urban Water - Umsetzung der EG-WRRL im städtischen Raum(2006-01-26T17:24:10Z) Gesenhoff, Julia; Schüler, AnkeItem Verkehrssystem Kiel: fit für die Zukunft?(2006-01-26T17:23:08Z) Baumgart, Sabine; Holz-Rau, ChristianItem Neue Möglichkeiten der Regionalplanung(2006-01-26T17:21:57Z) Kanafa, Kamila; Tum, CarstenItem ecomoebel - Innovation zur rechten Zeit, am rechten Ort(2006-01-26T17:19:50Z) Drenk, Dirk; Faltz, Laura; Fehsenfeld, Martin; Stottrop, DariaItem Scharnhorst-Ost - it isn't lost!(2006-01-26T17:17:11Z) Baumeister, Theresa; Englender, Gerard; Knappik, Magdalena; Lins, Julian; Lollert, Fabian; Plöger, Erik; Richling, Moritz; Schmid, Katrin; Schneider, Andreas; Ternka, Adrian; Pfefferle, Julian; Wanczura, Sylvia; Stierand, Rainer; Sinz, Alexandra
