title	ASCAAD 2023: C+++: Computation, Culture, and Context

summary	The ASCAAD 2023 theme focuses on Computation, Culture, and Context; a triad that is increasingly informing and reshaping the emerging dynamics of design and construction in the built environment of several regions in the Global South. Socio-cultural spheres, heritage roots, contextual relevance, and art and material culture have historically been the primary sources for design and construction innovation and uniqueness in such regions and contexts. Complex geopolitical events however have resulted in a shift towards a perplexed practice of post-modernist styles or imported Western models of design and production, coupled with some attempts to rebrand modernist and post-modernist approaches through critical regionalism and revolts against orientalist movements. Technology and computation have always been an active factor and tool in reflecting these practices. Advancements in computational design have in some ways sparked a latent intent to revive the character and heritage of rich civilizations. While this has led to growing interest within communities belonging to such rich history to adopt computational methodologies and practices, it has equally raised questions regarding authenticity, innovation and identity. Many of the recent attempts to shift away from Western-centered orientalist approaches have in reality not been that far, but have often further accentuated the superficial use of geometrical practices and pattern-based approaches in art, architecture, and urban design, characterized by stereotypical schemes in building interiors, façade screens, and spatial configurations.

summary	This article explores the correlation between the language of cinema and the architectural spatial discourse of power depicted in the film Equilibrium (Wimmer, 2002). This connection is examined through a discursive approach to communication studies. To analyze a specific sequence from the chosen film, a two-stage multimodal analysis was conducted. Initially, the visual analysis method proposed by Kress and Van Leeuwen (2006) designed for the representation of social actors, was employed. Subsequently, in the second stage, sociological and conceptual associations were drawn from the diverse semiotic resources identified in the first phase. The analyzed case revealed several intertextual relationships, among them; Hitler's figure recontextualized as an exemplifying archetype; the panopticon concept representing the spatial power dynamics; the presence of the German zeppelin symbolizing dominance and spreading propaganda through loudspeakers; the religious iconographic influence, its forms and symbols, contributing to a cultural identity inseparable from the history of the Western world.

summary	The research analyzes the impact of artificial beach nourishment in Joao Pessoa - PB, considering the increase in buildings and its environmental and social consequences. Urban beaches are particularly vulnerable to the growing effects of climate change. Artificial beach nourishment is proposed as a response to coastal erosion, but experts raise concerns about its high cost, ecosystem imbalance, destruction of fragile biomes, and impact on local communities. The research employs digital simulation (Scheer, 2014) through generative visual models as resources to analyze the beach nourishment project in Cabo Branco and Tambaú. Various visualization techniques and means are overlapped to simulate images linked to the real impacts of the proposed interventions. The study also explores the relationships between gray, green, and blue infrastructures and the effects on shading and ventilation caused by the buildings. The purpose is to understand the social, environmental, and urban dynamics' impacts on the city.

summary	The spatial distribution of urban commercial spaces significantly impacts the overall efficiency and vibrancy of adjacent neighbourhoods. As such, it is an important factor to consider during urban development. This study aims to examine the patterns of impact between commercial distributions and neighbourhood dynamics in a residential neighbourhood, based on the case study of a highly populated, thriving commercial, and culturally rich area situated in Mong Kok, Hong Kong. In this research, a series of numeric evaluations and statistical analyses of liveability and vibrancy metrics are presented, uncovering the tension created by existing commercial forms and local living patterns. This research started with multi-dimensional data mining, such as accessing planning data using Geographic Information Systems (GIS), perception data using Street View Images (SVI), and business performance data from Google; secondly, analysing the data via machine learning (ML) algorithm and statistical correlation to identify correlations overlaid with a mapping of spaces of measurable characteristics. The goal is to establish a measurable evaluation of the relationship between commercial vibrance and urban features that can further inform the impact of urban design strategies on fostering the vitality of community commercial centres.

summary	This paper discusses the potential of using data from social media and location data platforms to create cartographies that enhance our understanding of urban dynamics. Natural Language Processing (NLP) and sentiment analysis are highlighted as essential tools for comprehending and categorizing this data. The study conducted a systematic review of NLP and sentiment analysis applications in urban studies, covering 27 peer-reviewed journals and conference papers published between 2018 and 2023. The research classified applications into six categories: urban livability, governance and management, user and landscape perception, land use and zoning, public health, and transportation and mobility. Most studies primarily relied on data from social media platforms like Twitter and location data sources such as Google Maps and Trip Advisor. Challenges include dealing with irrelevant or misleading information in publicly available data and limited accuracy when analyzing sentiments of non-English-speaking populations.

title	The Role of Team Cognition in the Digital Media for Architectural Design Teams
source	C+++: Computation, Culture, and Context – Proceedings of the 11th International Conference of the Arab Society for Computation in Architecture, Art and Design (ASCAAD), University of Petra, Amman, Jordan [Hybrid Conference] 7-9 November 2023, pp. 1026-1036.
summary	This study delves into the intricacies of collaborative design teams, examining how Team Mental Model (TMM) and Transactive Memory System (TMS) correlate with the selection and elimination of ideas during the ideation phase. Utilizing team cognition theories, the research assessed the influence of various media on team decision-making and how the team's verbal interactions pertain to TMM and its relationship with decision-making. Using protocol analysis, the study examined the verbal communication processes that contribute to TMM formation, focusing on the aspects that correlated most with idea selection and rejection. The findings indicate a relationship between discussion duration and idea choice, as well as revisiting and developing ideas. Notably, the results revealed that ideas which received mixed feedback, encompassing both acceptance and rejection, signified team conflict. This research offers valuable insights into the dynamics of team ideation processes, though a more extensive examination of the specific conflicts within teams and a comparison with other studies is advocated.

title	Methodology for Improving Wind Comfort in a Cold Region Through Modular Urban Elements
source	De Luca, F, Lykouras, I and Wurzer, G (eds.), Proceedings of the 9th eCAADe Regional International Symposium, TalTech, 15 - 16 June 2023, pp. 5–14
summary	This paper discusses wind comfort improvement strategies as a crucial microclimatic issue in urban planning. The investigation used pergolas as a wind catcher/breaker element to improve wind comfort at the pedestrian level in Tallinn, Estonia, during extraordinarily windy and cold times of the year. We analyzed the impact of buildings and other surrounding elements on wind flow to design pergolas as windbreakers. Case studies include three urban areas. The wind flow has been simulated using Computational Fluid Dynamics (CFD) on the micro-climate scale using ENVI-met. The CFD analysis allowed us to understand urban wind flow phenomena and apply solutions to mitigate distress and guarantee more comfort. According to the CFD results, the urban zones show a high rate of wind speed under different meteorological conditions and, consequently, extreme wind discomfort. The analysis results of 48 scenarios based on different meteorological cases were used to select the most performative retrofit solution and provided insight into windbreak pergolas’ size, layout, and location to provide comfort. Thus, improved geometrical models of case studies were simulated and analyzed. The results showed that the designed pergolas offer high wind comfort at the pedestrian level, especially in open urban areas, and could assist municipalities, city planners, and urban designers in creating more comfortable and sustainable urban environments.

title	Gravity-Driven Sand Dynamics: A Technique for Optimizing Self-Organizing Dune Sand Patterns using Pouring, Gravity and Multi-Objective Computation
source	C+++: Computation, Culture, and Context – Proceedings of the 11th International Conference of the Arab Society for Computation in Architecture, Art and Design (ASCAAD), University of Petra, Amman, Jordan [Hybrid Conference] 7-9 November 2023, pp. 365-381.
summary	The paper offers an in-depth review of a digital/analog process for making sand-based patterns that can be computationally optimized as panels. These systems are intended for desert environments featuring dune sand as a primary material context. The paper discusses how the self-organization of dune sand can create patterns for shading and become computationally optimized for potential architectural outcomes in the form of a weather-responsive panel. Evolutionary computation assists in the methodology for performative design by incorporating weather-based analytics for sun, UV, heat, and wind. The methodology allows for material optimization that results in a series of design options that are highly responsive to local desert conditions using dune sand as the primary material. It begins with experiments in self-organizing sand sequences based on naturally occurring dune sand configurations. It then isolates the self-organizing characteristics atop localized laser-cut planes that allow the sand to pour and pile into specific configurations. The opening size and the number of openings were then studied, and configurations were frozen with a binder and used in a manifold of physical surface sequences. The project employs an optimization of these sand configurations based on the best possible arrangements for the size and number of openings that generate self-organized piles in a demonstrated desert location. The role of this computational and material process adds to the current dialogue of designing in extreme arid environments and aligns with the UN sustainability goals for sustainable communities, climate action, responsible consumption and production.

summary	Design charrettes and town hall formats are commonly used in the field of architecture to facilitate group ideation at multiple stages across a variety of stakeholders. Group ideation is critical to generate a wide range of solutions while covering all aspects of a defined problem. However, the format of group ideation often poses a multitude of challenges, including a lack of diverse ideation, difficulties in reaching consensus, imbalanced power dynamics, as well as maintaining focus throughout a group session. This paper explores how recent developments in AI frameworks could be utilized and assembled as a creative mediator in an architectural ideation process. The paper describes a framework and digital interface for AI-mediated group ideation where recent advancements in speech recognition, Natural Language Processing and Text-to-Image generation are leveraged to facilitate brainstorming processes. The paper first delves into the design of the framework and digital interface, taking into account in-person, remote and hybrid contexts, followed by the technical workflow and pilot evaluation methods used in this study. The resulting design is informed by AI-Mediated Communication, group dynamics and behavioral theories, along with core User Experience principles. The result takes the form of a visual ideation and transcription tool that allows users to ideate across conversational and visual methods.

title	Relational Fluid Dynamics: Optimizing for Airflow in Urban Form with Comparative AI Predictions
source	ACADIA 2023: Habits of the Anthropocene: Scarcity and Abundance in a Post-Material Economy [Volume 2: Proceedings of the 43rd Annual Conference for the Association for Computer Aided Design in Architecture (ACADIA) ISBN 979-8-9891764-0-3]. Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 542-548.
summary	In this paper, we propose a fast approximation of a particularly slow form of simulation: computational fluid dynamics (CFD). These tools are a crucial component in sustainability and comfort analyses, but their considerable computational requirements mean that only a small number of simulations can be undertaken for any given project—if at all. We demonstrate a predictive AI technique for estimating the results of CFD analysis; as this is nearly 300 times faster than traditional CFD methods, it can be used to quickly determine fitness within an optimization routine. In this case, the AI-predicted results have a mean accuracy of 89.0 to 90.8% relative to results derived using a traditional CFD technique. We also demonstrate an optimization technique for urban form using only predictive AI outputs for fitness. When optimizing for minimal wind velocity, randomly-placed urban aggregations eventually form recognizable vernacular solutions like wind breaks and perimeter walls. While a single prediction might only offer a rough approximation of real- world performance, optimization allows us to focus on the relative differences between predictions. This relational approach is inaccurate, of course, but clearly useful.

title	Visualization of Computer-aided Engineering Simulations on Multi-User Virtual Reality for Consensus Building
doi	https://doi.org/10.52842/conf.ecaade.2023.2.843

summary	Design plans for buildings must be proposed based on evidence and reviewed through various computer-aided engineering (CAE) simulations. The design and simulation results must be presented simultaneously in an easily understandable form, especially for non-experts such as project clients, to facilitate appropriate decision-making. This research proposes a multi-user virtual reality system that simultaneously visualizes 3-dimensional computer graphics (3DCG) models of a proposed design and the CAE simulation results. To facilitate discussions among stakeholders toward consensus-building, multiple users can immerse themselves as avatars in the 3DCG models. The position and rotation of each avatar are synchronized in real-time by stream communication through a server. The import and display of the simulation results on the model are also synchronized in real-time by a remote procedure call. A case study demonstrated that multiple users can share the simulation results and the 3DCG model displays of the proposed designs with real-time synchronization. The delay was less than 0.1 second.

title	A Nature-Inspired Experimental Method for Re-Generating Porous Architectural Systems Based on Environmentally Data-Driven Performance
doi	https://doi.org/10.52842/conf.caadria.2023.1.271
source	Immanuel Koh, Dagmar Reinhardt, Mohammed Makki, Mona Khakhar, Nic Bao (eds.), HUMAN-CENTRIC - Proceedings of the 28th CAADRIA Conference, Ahmedabad, 18-24 March 2023, pp. 271–280
summary	Weathering scenery, as one of the most representative time-consuming natural features, is associated with many characteristics through aspects of specialized morphology, porosity, adaptability, and regenerative ability. Because of its unique porous structure and majestic, randomly three-dimensional composition, it has inspired lots of creations in industrial design, art crafts, and graphic design fields. But in architectural generative design, very limited projects are related to weathering. However, in recent decades, the advancements in computer-aided design tools have made it possible to implement rigorous computational methods in complex geometrical systems. This research tries to learn from the weathering evolution and apply the characteristics in the pursuit of enriching nature-inspired architecture. The experiments will focus on one specific weathering behavior, using wind-blown particles as weathering agents, and introduce an experimental method of generating the performance-based porosity architectural system responding to environmental agents’ effects. Computational Fluid Dynamics (CFD), Bi-Directional Evolutionary Structural Optimization (BESO), and Swarm Intelligence are employed to negotiate between surface, structure, and environmental space. This study of the porosity architectural system is concerned not only with discovering new possibilities for intricate and complex nature-inspired architectural forms, but also with negotiating and considering humans and nature as equal decision-makers.

title	Genetic Algorithm-Based Building Geometric Opening Configurations Optimization for Enhancing Ventilation Performance in the High-Density Urban District
doi	https://doi.org/10.52842/conf.caadria.2023.1.251
source	Immanuel Koh, Dagmar Reinhardt, Mohammed Makki, Mona Khakhar, Nic Bao (eds.), HUMAN-CENTRIC - Proceedings of the 28th CAADRIA Conference, Ahmedabad, 18-24 March 2023, pp. 251–260
summary	The quality of the outdoor environment relates to urban ventilation performance. Poor wind conditions in high-density urban districts may lead to severe air pollution and deteriorate outdoor thermal comfort. The increase of openings in building geometry is one of the effective passive design strategies for enhancing the porosity of urban morphology and benefitting urban ventilation. However, the outdoor wind environment correlates with the opening configurations of building geometry complicatedly. For seeking the optimal opening configurations, a decision support tool is urgently needed. Our study proposes a genetic algorithm-based optimization workflow for the opening configurations of building geometry design by integrating Computational Fluid Dynamics simulation and parametric design. A residential block in Shenzhen, China is chosen as an example to show this workflow. The results demonstrate that when the porosity is 15%, the pedestrian-level mean wind speed, the wind speed dispersion, and the pressure difference between the front and rear of the downstream building can be optimized by 20.00%, 19.35%, and 183.33% on maximum. When the porosity is increased to 30%, these values are 42.22%, 16.13%, and 483.33%. The resultant opening distribution probability maps can support building design at an early stage to achieve a comfortable urban environment.

summary	Climate change has been increasing the vulnerability of cities to extreme weather events, especially those related to environmental dynamics already observed in each area. Considering that South America is one of the subcontinents that suffer the most from flooding, it is important to analyze how its cities have been preparing to face such extreme conditions. This paper aims to investigate the strategies indicated in climate action plans for mitigation and adaptation to flooding through the application of a parametric tool. To achieve this end, the methodology comprises five steps – from data collection to digital simulation. The results attained demonstrate that the strategies indicated in the plans are still very generic and incipient, so that the application of parametric methodologies of analysis and simulation can contribute to the searching for more effective and relevant actions.

title	4D Printing of Hygroscopic Wood Based Actuators for Climate Responsive Skin
doi	https://doi.org/10.52842/conf.ecaade.2023.1.439
source	Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 1, Graz, 20-22 September 2023, pp. 439–448
summary	Adaptive building systems aim to enhance user comfort and reduce energy consumption in buildings. However, sensing the environment and generating relevant motion requires complex systems. The high costs associated with the installation, maintenance, and energy consumption of traditional systems hinder their widespread adoption. A more efficient alternative can be found in nature by harnessing the intrinsic properties of materials. Recent studies inspired by pinecones showed that wood bilayers with different swelling and shrinking ratios can passively shape change in response to environmental humidity. The morphing direction is determined by fiber orientation, which can be controlled by extrusion-based 3D printers. The existing literature highlights several challenges in utilizing hygroscopic wood actuators for climate-responsive building skins, including the predictability of motion, response speed, and scalability. Hence, this research investigates the design space at both mesostructural and macrostructural levels for controlled, scaleable motion. To this end, a series of experiments were conducted in a controlled environment to observe the actuation dynamics. The experiments explored design parameters including thickness, porosity, bilayer ratio, layer orientation, and 3D printing parameters such as layer thickness and printing order. Collected data were utilized to construct a model that can predict the actuation and find the configuration for the required motion. Two implementations of this model are proposed. While the first design makes use of combined actuators for motion amplification, the latter employs pre-stressed bistability to control the timing of motion. Both designs were tested at scales of 1/2 and 1 to 1, using a wood-based filament and wood veneer as actuators, respectively. The results demonstrate that the use of multiple joined actuators significantly increases the actuation speed. Moreover, it is shown that the humidity level required to trigger the shape-shifts can be tuned thanks to the pre-stressed bistable structures. This is promising in terms of adaptability to diverse climates and enhancement of energy efficiency in buildings.

summary	This research aims to explore the use of Unmanned Aerial Vehicles (UAV) and Computer Vision as tools to collect spatial data (qualitative and quantitative) and the dynamics of use of public spaces and generate information for public managers. During the research, drones will be used to capture videos and images of a case study selected with the help of a team of project partner managers. The collected data will be translated into information for accurate and efficient decision-making, based on the use of knowledge extraction and data mining strategies. The extracted knowledge will be presented to managers as a tool prototype that helps in the design and management of public spaces present in areas with great tourist influence. The adoption of new technologies can strengthen the means of application and revitalize the global partnership for the development of innovative built environments, thus impacting on the UN's sustainable development goals.

title	Biomimetic Form-Finding Study of Bone Needle Microstructure Based on Sponge Regeneration Behavior
doi	https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_8
source	Proceedings of the 2023 DigitalFUTURES The 5st International Conference on Computational Design and Robotic Fabrication (CDRF 2023)
summary	The concept of “nature-algorithm-structure” refers to a digital design method in architecture that draws inspiration from nature, extracting its mathematical and physical conceptual models to construct structural systems with parameters. This study aims to address the challenge of parametric form-finding in reticular tension structures. By observing the phenomenon of “sponge regeneration”, we further illustrate the generation and optimization of reticular tension structures through the hierarchical structures of “monomer”-“path”-“mesh”. Tensile structural systems are rebound forms, and their analytical models must account for their nonlinear characteristics and the existence of equilibrium self-course. Starting from the growth dynamics of “sponge regeneration behavior”, this paper extracts the logic behind it: sponge monomers combine randomly into partial units under the condition of shredding and discrete, forming a single organism through aggregation. The multi-dimensional bone needle serves as a structural component, enabling multi-axis reorganization, while the multi-directional mesh surface as a morphological component realizes multi-branch reproduction, forming a natural “network tension structure”. This study focuses on the biomimetic form-finding of bone needle microstructure, drawing inspiration from sponge regeneration behavior. By analyzing the growth dynamics of sponge regeneration, we aim to develop a better understanding of the principles behind the formation of bone needle microstructure. This finding provides significant reference for the development of modern structures and promotes the bioshape and optimization of tensile structures.

summary	The water lily (EICHORNIA CRASSIPESSE) is an invasive plant that affects bodies of water throughout the world, generating serious socio-environmental problems. This research uses an experimental approach to study the feasibility of using water lilies to make biobased materials. To achieve this, a hybrid methodology was formulated based on Design Thinking and the Material Driven Design Method divided into three stages called exploratory, material, and functional. The results show a biobased biomaterial with different applicability characteristics in limited use that takes advantage of a harmful and underutilized invasive plant. Establishing its virtue to replace traditional materials. These results show that the water lily is competent as a raw material to be transformed into future materials as an alternative to current environmental problems while attacking its overpopulation.

summary	This research critically challenges the conventional perception of drawings as mere technical blueprints and delves into the intricate integration of design ideation, abstraction, and speculation with geometrical manipulations and semantic labelling. By focusing on unconventional architectural design studio experiments at the undergraduate level, the study aims to explore the role of creativity in speculative drawing. It adopts a 3- dimensional design thinking process that transcends the rigid constraints of traditional drawings and embraces the fluidity of representational norms. Furthermore, the paper elucidates on the pedagogical aspects of the design studio, including the unstructured creativity inherent in the design process. The methodology employed in this study is exemplified through different stages of the design studio, incorporating a variety of representations such as 2D, 2.5D, and 3D,encompassing scalar, geometric, and material transfigurations. To assess the outcomes of the studio, the research utilises correlation diagrams that establish connections between digital drawing features at different stages and the unstructured creativity manifested in the final design. These scatter and correlation diagrams capture the syntactic relationships between the objects within digital drawings. The findings of this study reveals insight on the nuanced interplay between intuitive, reflective, and retrospective aspects of unstructured creativity during the design ideation process. By unraveling the intricate role of digital design tools and methods this research contributes to a deeper understanding of of how design ideation is generated and manifested through the dynamic interplay of the modulating compounds of drawing objects. It highlights the significance of meaningful, conceptual, and speculative representations that directly relate to the creation of buildable forms and architectural spaces. Through its critical insights, this study paves the way for advancements in the field of CAAD and offers valuable perspective for architectural education and practice.

title	Rapid Deployable Shell Structures: Bi-layer Bending Systems for Pop-Up Architectural Morphologies

summary	Architects have often employed nature as a tool for design. However, it is not until recently nature has been examined as a system of complex mechanisms. This area of study is known as Biomimetics. This research situates itself within this field by deeply investigating one such biological system, the bi-layer bending mechanism in coiling tendrils, and exploring its relevance in architectural design. This mechanism uniquely integrates the flexibility of pliable materials with the strength of rigid materials to create rapid curling responses when stimulated. When this mechanism is translated into an architectural system, it provides the opportunity to leverage two opposing materials to create self-bending structures. Particularly, the authors found a great advantage in utilizing this system for rapidly deployable shell structures. The inventive use of this bending mechanism creates bespoke morphologies with a few simple elements, creating versatile solutions which can adapt to various conditions. Through this research, the authors investigate this mechanism in a design setting and explore its potential applications at an architectural scale. This work highlights the significance of the application of biological principles in the architecture and design discipline.
