Item Open Access HAUS TRADITION GLÜCK - Die Korrelation traditioneller Architektur und Stadtstrukturen mit dem subjektiven Wohlbefinden der Altstadtbewohner von Tunis(2021) Humpert, Raoul Cyril; Hannemann, Christine (Prof. Dr.)Das Haus, die Tradition und das Glück; die drei charakteristischen Termini dieser Forschung stehen explizit und markant in ihrer direkten Aneinanderreihung und sollen als Hyperonyme einer Metaebene für den folgenden Diskurs dienen. Diese setzt sich mit der Wechselbeziehung und Symbiose dieser drei Themenfelder auseinander. HAUS - als Synonym für (domestikale) Architektur und Stadtstruktur sowie Planung. TRADITION - für traditionelles Bauen und verwandte traditionelle Bräuche sowie kulturelle Gegebenheiten. GLÜCK - als Überbegriff von Wohnzufriedenheit, Lebensqualität, Glück und subjektivem Wohlbefinden in Bezug zur gebauten Umwelt. Die Zielsetzung der vorliegenden Forschungsarbeit ist die Erkenntnis darüber, ob, inwiefern und auf welche Weise traditionelle Architektur und traditionelle Stadtstrukturen das Wohlbefinden von Bewohnern beeinflusst. Prinzipiell setzt sich die Abeit somit aus zwei Teilen zusammen. Im ersten Teil, der theoretisch-konzeptionellen Rahmung, wird sich in einem (Architektur-)theoretischen Diskurs mit der Forschungsthematik auseinandergesetzt. Darauf aufbauend, wird das Konzept für die Feldforschung entwickelt. Deren Ergebnisse die Grundlage des zweiten empirischen Teils der Arbeit bilden.Item Open Access Regelungskonzepte für schaltbare Verglasungen zur Optimierung des Innenraumkomforts(2019) Husser, Marzena; Sobek, Werner (Prof. Dr.-Ing. Dr.-Ing. E.h. Dr. h.c.)Die Fassade, als Schnittstelle zwischen dem Innen- und dem Außenraum, wird mit zahlreichen Anforderungen konfrontiert. Wird im Innenraum eine thermische und eine visuelle Behaglichkeit angestrebt, so ist dies allein durch die Auslegung traditioneller Fassadenverglasungen mit invarianten Eigenschaften, ohne zusätzliche Funktionselemente und Energieeinsatz, meistens nicht möglich. Bei adaptiven Verglasungen kann die Licht- und Energietransmission in bestimmten Wellenlängenbereichen verändert werden, was neue bauphysikalische Potentiale zur Folge hat. Im Rahmen der vorliegenden Arbeit wurde eine elektrisch steuerbare Verglasung auf Flüssigkristallbasis (s.g. TN-Verglasung) behandelt. Das Ziel der Arbeit war die Untersuchung der Möglichkeiten einer Komfortsteigerung (Optimierung sowohl des visuellen als auch des thermischen Komforts) bei gleichzeitiger Minimierung des Raumenergiebedarfs durch die Anwendung unterschiedlicher Regelungsstrategien der genannten Verglasung.Item Open Access BIM for CREM: exploring the benefit of building information modelling for facility management in corporate real estate management(2022) Benn, Maximilian; Stoy, ChristianThe implementation of BIM in FM has been of steadily growing interest for academic research. Yet the benefits of BIM for the FM in CREM have, to the present day, been explored to a limited extent. As research on BIM for FM in CREM remains narrowly investigated, this study follows an exploratory approach to formulate implications for further research directions. Therefore, a four-stage procedure was adopted: (1) identification and definition of BIM uses for FM in CREM; (2) validation of the BIM uses for FM in CREM and the expert survey questionnaire; (3) assessment of each BIM use’s benefit by experts; and (4) analysis of the correlations between BIM uses’ benefit assessments and the respondents’ industries, the resulting associations, and the prioritisation for the development of BIM uses for FM in CREM. Based on that methodology, it was shown that the BIM use for FM in CREM with the highest priority for development is 46 Facilities and Equipment: Repair and Renewal. The BIM use with the lowest priority is 21 Visualisation. As a result, four implications on the development of BIM uses for FM in CREM were formulated regarding case studies, information requirements, and technical requirements, as well as process and personnel requirements.Item Open Access Nachhaltige Transformation gestalten : Baukultur in ländlichen Räumen in Baden-Württemberg(Stuttgart : Universität Stuttgart, Städtebau-Institut, Lehrstuhl für Stadtplanung und Entwerfen, 2023) Baum, Martina; Deilmann, Philipp; Königsdorfer, Richard; Ludwig, Ann-KathrinDie Studie „Nachhaltige Transformation gestalten - Baukultur in ländlichen Räumen in Baden-Württemberg“ ordnet den Baukulturbegriff geschichtlich ein und entwickelt daraus eine neue Definition mit transformativem Potenzial, die eine zukunftsgerichtete nachhaltige Perspektive auf die ländlichen Räume in Baden-Württemberg ermöglicht. Eine qualitative Bestandsaufnahme der Baukultur zeigt sowohl die Problematik als auch die Potenziale von gegenwärtigen baukulturellen Entwicklungen, insbesondere die herausragende infrastrukturelle Lage des Landes. Die einzelnen Elemente der Baukultur - Gebäude, Kulturlandschaften und Infrastrukturen - werden dabei über Kartografien und Fotografien erfasst und ausgewertet. Darauf aufbauend wurden konkrete Ziele, Kriterien und Handlungsempfehlungen erarbeitet, die eine nachhaltige Transformation der gebauten Umwelt in den ländlichen Räumen Baden-Württembergs ermöglichen.Item Open Access Granular architectures : granular materials as "designer matter" in architecture(Stuttgart : Institute for Computational Design and Construction, University of Stuttgart, 2020) Dierichs, Karola; Menges, Achim (Prof.)The thesis investigates designed granular materials in architecture. Granular materials are defined as high numbers of particles larger than a micrometre, between which mainly short-range repulsive contact forces are acting. In a designed granular material the geometry and material of the individual particle are determined by a designer. Consequently, the overall granular material can have characteristics which are novel in comparison to non-designed granular materials. In architecture, designed granular materials are understood to have new characteristics which fulfil specific architectural performance criteria. The relevance of designed granular materials in architecture is threefold. All granular materials are both fully recyclable and reconfigurable due to the fact that the individual particles are in no way bound to each other. These first two aspects alone make any granular material, whether it is designed or not, a highly pertinent strand of architectural design research. However, designed granular materials, in addition to being recyclable and reconfigurable, bear the potential for the development of entirely novel material behaviours. In the context of architecture, designed granular materials can be considered as a form of "material systems", and more specifically as a sub-group of "aggregate systems". In the wider transdisciplinary context, designed granular materials for architecture can be considered a form of "designer matter (DM)". "Designer matter (DM)" is understood as matter which is designed in its structural characteristics at its mesoscale rather than its macro- or its microscale. The current state of research into designed granular materials is presented for both architecture and granular physics, on a conceptual as well as on a project-based level. In this context the thesis aims to establish and validate a first version of a comprehensive design system for exploring designed granular materials in architecture and for interfacing with granular physics. The research development of this thesis is presented and evaluated with respect to the practical, methodological and conceptual foundations which have been laid during this phase. The methods are introduced in terms of methodological frameworks, tools and techniques and the applied research methodology. The core part of the thesis comprises a design system with a related design system catalogue as well as two case studies. The design system is established for particle systems and for related construction systems. It formulates the basic system categories and corresponding parameters. The design system catalogue is presented in the appendix and summarizes tests which investigate individual aspects of the overall design system for particle and construction systems. Each of the two case studies explores the integration of a different set of design system categories. They were conducted both through full-scale prototypes and a related set of tests with statistical repetition. Case study 1 investigates vertical structures made from a designed granular material consisting of highly non-convex particles. Case study 2 combines two designed granular materials, one consisting of convex particles and the other of highly non-convex particles, in order to form spatial enclosures. The case studies are evaluated with respect to their practical, methodological and conceptual contributions to architectural design research. The thesis is summarized and its contributions are assessed in conclusion both with respect to the field of architecture and for the field of granular physics. Further research in the field of designed granular materials in architecture can be conducted on the practical, methodological and conceptual levels of design. On the practical level, in the area of particle systems the investigation of graded granular materials, of different mechanical properties of the particles' material or of designed granular materials consisting of particles with variable geometry is highly promising. In the area of construction systems, the development of behavioural models of robotic construction is very relevant. Another key direction is for the construction systems to become increasingly simple, while the particles are progressively designed to perform parts of the construction process by themselves. On the methodological level, the integration of "inverse" design methods is the logical next step. This can be done on the basis of the proposed design system. On the conceptual level, the framework of "designer matter (DM)" needs to be further established both as a transdisciplinary model and within the field of architecture. Only then can designed granular materials be fully discussed as one form of "designer matter (DM)" in architecture. Key to any further development of the overall research field is the integration of the two fields of architecture and granular physics.Item Open Access Implementing asset information requirement templates for corporate real estate management: a study in the chemical industry(2023) Benn, Maximilian; Stoy, ChristianResearch on building information modelling (BIM) for corporate real estate management (CREM) in the chemical industry remains limited. This is largely due to a lack of documents supporting BIM adoption and implementation. The present study identifies, compares, and applies different approaches to the definition of asset information requirements (AIR) templates for facility services in the chemical industry. It subsequently translates the results into recommendations for AIR template implementation and formalises them into implementation steps. The results indicate that process diagrams are an expedient approach to the definition of AIR templates. Recommendations for their implementation concern information management software, static data prioritisation, accuracy limitations, asset types and sub-types, and stakeholder involvement. The present study contributes to the body of knowledge by identifying an expedient approach to the definition of AIR templates, providing AIR for four BIM Uses, and proposing an AIR template implementation framework for CREM in the chemical industry.Item Open Access Ludwig Hilberseimer und das Primitive in der Kunst(2018) Jüttner, Frank; Philipp, Klaus Jan (Prof. Dr. phil.)Item Open Access Autonomous robotic additive manufacturing through distributed model‐free deep reinforcement learning in computational design environments(2022) Felbrich, Benjamin; Schork, Tim; Menges, AchimThe objective of autonomous robotic additive manufacturing for construction in the architectural scale is currently being investigated in parts both within the research communities of computational design and robotic fabrication (CDRF) and deep reinforcement learning (DRL) in robotics. The presented study summarizes the relevant state of the art in both research areas and lays out how their respective accomplishments can be combined to achieve higher degrees of autonomy in robotic construction within the Architecture, Engineering and Construction (AEC) industry. A distributed control and communication infrastructure for agent training and task execution is presented, that leverages the potentials of combining tools, standards and algorithms of both fields. It is geared towards industrial CDRF applications. Using this framework, a robotic agent is trained to autonomously plan and build structures using two model-free DRL algorithms (TD3, SAC) in two case studies: robotic block stacking and sensor-adaptive 3D printing. The first case study serves to demonstrate the general applicability of computational design environments for DRL training and the comparative learning success of the utilized algorithms. Case study two highlights the benefit of our setup in terms of tool path planning, geometric state reconstruction, the incorporation of fabrication constraints and action evaluation as part of the training and execution process through parametric modeling routines. The study benefits from highly efficient geometry compression based on convolutional autoencoders (CAE) and signed distance fields (SDF), real-time physics simulation in CAD, industry-grade hardware control and distinct action complementation through geometric scripting. Most of the developed code is provided open source.Item Open Access Toward reciprocal feedback between computational design, engineering, and fabrication to co-design coreless filament-wound structures(2024) Kannenberg, Fabian; Zechmeister, Christoph; Gil Pérez, Marta; Guo, Yanan; Yang, Xiliu; Forster, David; Hügle, Sebastian; Mindermann, Pascal; Abdelaal, Moataz; Balangé, Laura; Schwieger, Volker; Weiskopf, Daniel; Gresser, Götz T.; Middendorf, Peter; Bischoff, Manfred; Knippers, Jan; Menges, AchimItem Open Access A measurement-based framework integrating machine learning and morphological dynamics for outdoor thermal regulation(2025) Alinasab, Niloufar; Mohammadzadeh, Negar; Karimi, Alireza; Mohammadzadeh, Rahmat; Gál, TamásThis study presents a comprehensive investigation into the interplay between machine learning (ML) models, morphological features, and outdoor thermal comfort (OTC) across three key indices: Universal Thermal Climate Index (UTCI), Physiological Equivalent Temperature (PET), and Predicted Mean Vote (PMV). Based on a comprehensive field measurement for 173 urban canyons, proper dataset for summer outdoor thermal condition was provided. Concurrently, six distinct ML models were evaluated and optimized using Bayesian optimization (BO) technique, considering performance indicators like weighted accuracy, F1-Score, precision, and recall. Notable trends emerged, with the CatBoost Classifier demonstrating superior performance in UTCI prediction, the Random Forest classifier excelling in PET estimation, and the XGBoost Classifier achieving optimal PMV prediction. Furthermore, the study delved into the influence of morphological features on OTC, prioritizing factors using SHAP values. Results consistently identified 90-degree orientation, street width, and 180-degree orientation as pivotal factors influencing OTC, with varying degrees of sensitivity across different classifications of thermal stress. Analysis of binary SHAP values unveiled intricate relationships between urban features and OTC indices, emphasizing the critical influence of street orientation on regulating outdoor thermal environments for UTCI and PET scenarios. Surprisingly, street width emerged as the foremost influential factor within the PMV index, challenging established trends and highlighting the complexity of thermal comfort modeling. Additionally, current research delineates the multifaceted impact of street width on microclimate dynamics, enriching our understanding of urban thermal dynamics and emphasizing its role in mitigating thermal stress within urban environments.
