Im Zuge des fortschreitenden Klimawandels ergeben sich besondere Herausforderung für Städte. Um diese sowohl im Hinblick auf bestehende Klimaschutzziele als auch im Sinne der Klimaanpassung zukünftig
nachhaltig zu gestalten, besteht ein großer Handlungsbedarf. Um einzuschätzen, welche Maßnahmen dafür sinnvoll sind, werden in dieser Arbeit eine Reihe von Dimensionen untersucht. Es handelt sich um die
Bereiche, Sanierung, Energieträgermix, PV-Anlagen, Bäume sowie der motorisierte Individualverkehr. Die Untersuchung erfolgt in Form einer Sensitivitätsanalyse. Zusätzlich sollen auch mögliche Wechselwirkungen
zwischen diesen Themen untersucht werden. Da Städte sehr heterogen in ihren Strukturen sind, werden die Dimensionen am Beispiel von vier Quartieren mit jeweils unterschiedlichen Archetypen analysiert. Die
Berechnungen werden mithilfe von Simulationsprogrammen durchgeführt. Als Vergleichskennwerte werden CO2-Emissionen und Energiebedarfe herangezogen. Daneben wird auch der Einfluss auf die Lebensqualität der Bewohner beleuchtet. Insgesamt kann dabei festgestellt werden, dass durch Änderungen in diesen Dimensionen sowohl der Energiebedarf als auch die CO2-Emissonen stark gesenkt werden können. Dabei treten zwischen den Dimensionen Bäume und PV sowie Bäume und Sanierung Wechselwirkungen auf. Diese sind klein. Die stärksten Effekte in Bezug auf CO2-Reduzierungen stecken in der Dimension Energieträgermix, gefolgt von Sanierung. Die schwächsten Effekte sind in der Dimension Bäume zu verzeichnen. Diese haben dafür wiederum starke Auswirkungen auf das Mikroklima und die Lebensqualität der Bewohner. Insgesamt
sind auch zwischen den Quartiersarchetypen Unterschiede sichtbar. So weisen Ein- und Zweifamilienhausquartiere das größte Änderungspotenzial auf, während neue Innenstadtquartiere das niedrigste Potenzial zeigen. Insgesamt ist aber in allen Quartieren das Änderungspotenzial durch Anpassung der Dimensionen hoch.
Die Bachelorarbeit befasst sich mit der Untersuchung von Strategien zur Reduktion des Kühlbedarfs und thermischer Belastungen in Innenräumen durch Haushaltskühlgeräte. Ziel ist es, das Potenzial der Abwärme solcher Geräte zu analysieren und innovative Ansätze für deren Wärmeabführung zu entwickeln.
Die Arbeit umfasst eine detaillierte Potenzialanalyse, die zeigt, dass handelsübliche Kühlgeräte durch gezielte Abwärmeabführung zur Verbesserung der thermischen Behaglichkeit beitragen können. Mithilfe thermischer Simulationen und experimenteller Messungen werden verschiedene Szenarien untersucht, darunter Haushaltsanwendungen sowie alternative Einsatzbereiche wie kleine Gewerbeeinheiten.
Die Ergebnisse verdeutlichen, dass die gezielte Abführung der Abwärme im Sommer eine signifikante Reduktion der Raumtemperatur bewirken kann, während sie im Winter zur Heizungsunterstützung genutzt werden kann. Durch den Versuchsaufbau konnte die Machbarkeit des Konzepts an einem Einzelgerät demonstriert werden. Zudem zeigen die wirtschaftlichen Analysen, dass es sich hierbei um eine kostengünstige Nachrüstlösung handelt, die eine effiziente Alternative zum Einbau eines Klimageräts in kleingewerblichen Anwendungen darstellt.
Die Ergebnisse der Arbeit bieten nicht nur einen Beitrag zur Steigerung der Energieeffizienz in Gebäuden, sondern setzen auch den Grundstein für weiterführende Untersuchungen zur Optimierung, Skalierung und Ausarbeitung dieses Systems.
Bioswales are a sustainable solution for climate change adaptation and stormwater management, enhancing urban resilience. Urban areas face increasing risks of flooding and environmental challenges due to extensive impermeable surfaces and inefficient drainage systems.
Recent advancements in Building Information Modelling (BIM) provide powerful tools for designing nature-based solutions tailored to local conditions. However, their potential in the context of bioswale design remains underexplored. Integrating bioswales into urban infrastructure presents several challenges, including soil permeability, existing drainage systems, topography and land slopes, land-use constraints, and the need to develop workflows that address technical, ecological, and social dimensions.
This study employs an inductive approach, combining qualitative and quantitative methods to evaluate the design and implementation of bioswales. The research includes a case study of Breitscheidstraße in Stuttgart, where Civil 3D and InfoDrainage were used to model and analyze the effectiveness of bioswales in stormwater management. The case model analysis of Breitscheidstraße demonstrates how bioswales, as part of Sustainable Urban Drainage Systems (SuDS), can effectively retain stormwater volumes, unlike the existing drainage system, which failed under similar scenarios with a rainfall intensity of 35 mm/h. Bioswales also introduce cultural and recreational functions to the area.
This research expands the understanding of bioswale performance and their contribution to urban resilience. The developed bioswale design toolbox for my case study provides practical recommendations for urban planners and landscape architects, enabling solutions tailored to diverse environmental scenarios. Leveraging modern modeling tools like BIM ensures precise adaptation of bioswales to site-specific characteristics and project requirements. The integration of advanced design and analysis approaches improves the efficiency of bioswale implementation, contributing to the sustainable development of urban environments.
Das sog. „kompakte Hofhaus“ wurde als neuartiger Hofhaustyp an der HFT Stuttgart entwickelt und untersucht. Zu Quartieren addiert stellt er den Bewohnern bei geringem Landverbrauch urbane Lebensräume zur Verfügung und kann hohe Dichte, Nutzungsdiversität sowie ein hohes Maß an Privatheit und Wohnqualität in Innen- wie Außenräumen miteinander vereinigen, in Neubau- wie in Bestandsituationen. Hinsichtlich der Ziele knüpft diese Forschung damit unmittelbar an die Stuttgarter Weißenhofsiedlung von 1927 an.
Urban centres are undergoing a transformation towards becoming Smart Sustainable Cities, with the integration of physical, digital, and human systems at the forefront. Smart Mobility, a crucial component of this development, integrates technology in urban areas to improve quality of life, environmental protection, and urban mobility. It aims to improve issues of urban transportation and environmental preservation, particularly in the last mile of urban journeys. The research also aims to answer the research question What are the guidelines for planning micromobility infrastructure to improve last mile connectivity in cities?
The research focuses on the Smart Mobility component of Smart Cities and addresses the issues with a specific focus on last-mile connectivity in urban transportation. The research objective is to investigate the potential of micro-mobility options such as e-scooters and e-bikes to improve sustainability and provide essential connectivity. This master thesis employs a mixed-method approach to investigate the critical factors that contribute to the success of micro-mobility infrastructure projects, user needs, and challenges, and provides practical recommendations for local authorities and urban planners. The research includes a comprehensive literature review, survey analysis, and explanatory case studies of Amsterdam and Copenhagen, in order to gain a deeper understanding and provide essential connectivity. However, this also highlights the need for better infrastructure and regulations to fully integrate these new modes of transportation into existing transit networks.
The effectiveness of the developed guidelines is validated through a comparison with the strategic plans of the Metropolitan Transportation Authority (MTA) for micro-mobility and last mile connectivity infrastructure. This comparison provides insight into how the guidelines align with the transportation infrastructure deployment and operation plans of the MTA, which are essential for ensuring the safety, efficiency, and accessibility of the transportation system while taking into account the needs of different stakeholders.
This thesis offers a comprehensive understanding of how to plan and implement micro-mobility infrastructure to enhance last-mile connectivity in cities and serves as a valuable resource for urban planners and transportation departments. Further research should be undertaken to explore how the guidelines provided in this study can be implemented in different micromobility options with varying transportation systems and urban structures.
Creating an immersive Augmented Reality (AR) experience requires aligning the digital content with the real environment where the digital content appears and interacts in a similar way to a real object. For that, the virtual object must persist in its position across sessions and be occluded completely or partly depending on whether a real-world object is in the line of sight. This research makes use of the cutting-edge technology available in the field of AR/MR, the Microsoft HoloLens 2.0, where the in-device Time of Flight (ToF) camera is used to scan the environment to create a Spatial Map. LOD1 city model enriches the Spatial Map and in addition, is used as an occlusion mask via a custom rendering pipeline. Spatial Anchors can be tracked using the Simultaneous localization and mapping (SLAM) used in conjunction with World Locking Tools to anchor the whole scene to the real-world coordinates. The developed occlusion effect is used in urban planning scenarios to introduce a new area design featuring a car-free environment. The proposed method is evaluated based on performance indicators including the number of Frame Per Second (FPS) since it’s highly correlated to user comfort. The findings of the users’ study demonstrate that the occlusion effect achieves its purpose since most of the participants reported enhancement in the depth perception and overall experience by enabling the occlusion screening.
Urban planners and designers often use grayscale masking filters to highlight a selected urban feature and its context without the overwhelming information. With the rising interest in applying augmented reality (AR) technology into the field of urban planning for increasing social engagement, this thesis aims to develop an outdoor mobile AR application that visualizes the urban environment using the mentioned grayscale masking filters. The application is able to apply the grayscale masking filter to the designated buildings in Nordbahnhof, Stuttgart when the device's camera is pointing to them. State of the art of outdoor mobile AR technologies are studied and reviewed. This thesis proposes the concepts and methodology of the video-based AR visualization and the development of the app. The implementation of the concepts and methodology is documented and the implementation process and result are evaluated.
In the Architectural Design Process (ADP), the communication of design ideas between professionals and stakeholders is a complex task that currently still uses outdated methods. Despite advances in the use of Computer-Aided Design (CAD) and Building Information Modelling (BIM)
tools, products are still presented in 2D on flat screens or paper, leaving too much information for the end user to interpret. The use of Augmented Reality (AR) and Mixed Reality (MR), which allow the overlay and direct interaction of digital objects with the real environment, is shown to be one of the key factors for the next breakthrough in technology for the development of the Architecture, Engineering and Construction (AEC) industry. This research uses the concept of serious gaming to propose a workflow for the development of an AR/MR prototype application for the Microsoft HoloLens2 head-mounted device (HMD). This, through the use of the Unity game engine and its native video game development functionalities, is able to capture the interactions made in an architectural design project and transfer them to be executed in Autodesk Revit BIM software in a studio case of office layout design. The results of a first approach test user experience survey conducted, suggest that the proposed approach can facilitate the communication of ideas between the architect and the end user, makes it easier to understand the design proposal versus traditional methods, and that it shows potential for use in AEC.
Das Projekt INSPIRER zielte darauf ab, Augmented Reality (AR) zur interaktiven Bürgerbeteiligung in der Stadtplanung einzusetzen. Durch eine standortbezogene Visualisierung von Planungsentwürfen konnten Bürger*innen geplante Veränderungen direkt vor Ort erleben. Der entwickelte AR-Client mit einem innovativen Point Cloud Matching-Tracking-System ermöglichte eine präzise Platzierung und Stabilisierung virtueller Inhalte ohne GPS.
Im Rahmen des Projekts wurde ein 3D-Stadtmodell-Server entwickelt, der Bestands- und Entwurfsdaten verwaltet. Dies erlaubte die nahtlose Integration von Stadtplanungsmodellen in AR-Anwendungen. Ein zentraler Anwendungsfall war die Visualisierung eines geplanten Kreisverkehrs in Fellbach, wobei die AR-App es ermöglichte, das 3D-Design des neuen Stadtbereichs direkt vor Ort zu erleben.
Die Forschungsergebnisse wurden evaluiert und zeigen, dass AR-basierte Beteiligungsformate das Verständnis und die Akzeptanz von Stadtplanungsprozessen erheblich verbessern können. Die entwickelte Technologie wurde veröffentlicht und als Open Access zugänglich gemacht, um zukünftige Entwicklungen in der digitalen Bürgerbeteiligung zu unterstützen.
Integrating Building Information Modeling (BIM) and Geographic Information Systems (GIS) offers transformative potential for managing urban infrastructure within the framework of smart cities. The thesis explores the integration of BIM and GIS through three stages: a literature review to identify challenges and opportunities, a prototype model demonstrating practical applications, and actionable guidelines to support stakeholders in urban planning and infrastructure management.
A literature review establishes the theoretical foundation, highlighting the complementary roles of BIM and GIS, existing standards like ISO 19650 and CityGML, and the barriers to seamless integration, including data interoperability, semantic inconsistencies, and technical complexities. The review further examines key concepts such as BIM dimensions, and LOD concepts in BIM and GIS, which define the granularity of information at various stages of project workflows. Additionally, widely adopted classification systems, such as UniClass, OmniClass, and DIN 276, are discussed for their role in standardizing data organization and enhancing interoperability.
The study develops a prototype model, leveraging tools such as ArcGIS Pro, Revit, and GDAL, to demonstrate the integration of real-world datasets from Stuttgart, Germany. The prototype incorporates digital terrain models, cadastral data, and 3D building geometries, employing various integration methods, including direct use of BIM files, geodatabase conversion, and Building Scene Layers. These methods are evaluated for their advantages, limitations, and applicability to diverse urban planning scenarios.
The research provides actionable best practices based on insights from the literature review and prototype development. These include developing a clear understanding of project objectives, establishing standardized data workflows to address interoperability challenges, defining clear roles for stakeholders, and fostering cross-disciplinary collaboration. The recommendations highlight the importance of leveraging appropriate software solutions and ensuring consistent use of spatial reference systems throughout the project to enhance accuracy and facilitate seamless integration.
This thesis concludes that BIM-GIS integration is a critical enabler for smart city initiatives, offering a framework for managing urban infrastructure. Future research should explore the application of emerging technologies, such as digital twins and IoT, to further advance the integration of BIM and GIS in dynamic urban environments.
