title	Building-GNN: Exploring a co-design framework for generating controllable 3D building prototypes by graph and recurrent neural networks
doi	https://doi.org/10.52842/conf.ecaade.2023.2.431
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 2, Graz, 20-22 September 2023, pp. 431–440
summary	This paper discusses a novel deep learning (DL) framework named Building-GNN, which combines the Graph Neural Network (GNN) and the Recurrent neural network (RNN) to address the challenge of generating a controllable 3D voxel building model. The aim is to enable architects and AI to jointly explore the shape and internal spatial planning of 3D building models, forming a co-design paradigm. While the 3D results of previous DL methods, such as 3DGAN, are challenging to control in detail and meet the constraints and preferences of architects' inputs, Building-GNN allows for reasoning about the complex constraint relationships between each voxel. In Building-GNN, the GNN simulates and learns the graph structure relationship between 3D voxels, and the RNN captures the complex interplaying constraint relationships between voxels. The training set consists of 4000 rule-based generated 3D voxel models labeled with different degrees of masking. The quality of the 3D results is evaluated using metrics such as IoU, Fid, and constraint satisfaction. The results demonstrate that adding RNN enhances the accuracy of 3D model shape and voxel relationship prediction. Building-GNN can perform multi-step rational reasoning to complete the 3D model layout planning in different scenarios based on the architect's precise control and incomplete input.

title	ColorCraft: A Mixed-Initiative System for Supporting Creativity in Coloring Visual Patterns
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. 781-797.
summary	Focusing on generating, using, and exploring color schemes and applying them to visual patterns, this paper questions how co-creation systems can support artists’ creativity in coloring and explore possible UX features for such systems. Through an applied research project, we demonstrate a prototype system, ColorCraft that incorporates mix-initiative interaction methods building on an extensive literature review and expert interviews. Through ColorCraft, we propose possible UX techniques for facilitating the generation of color compositions and assigning colors to visual patterns, allowing for the exploration of alternative pattern colorings. We aim to enhance co-creative processes and provide tool features for applying colors on patterns in, e.g., graphics design, architecture, and interface design. The formative evaluation of the prototype shows promising feedback and insights for improving coloring applications. The study contributes to our understanding of problem characterization of coloring, and the artists’ expectations from tools that will augment their creative exploration of pattern coloring.

summary	During the 21st century, the figure of the elderly is increasingly central in society. It is important to promote the relationship between generations to support active and more balanced aging in the city center, without age segregation (like specific geriatric equipment), thus allowing a natural human renewal of cities, without the expulsion of younger generations to the suburbs, and the institutionalization of older people. This article will focus on some integrative experimental models of universal design combining Portuguese legislation on Residential Structures for the Elderly, Assisted Living and the Housing Law based on trends revealed by Social Support Satisfaction and Quality of Life surveys WHOQOL- BREF – WHO to this group, generating architectural design solutions through the Grammar of Form that integrate that legislation, in order to transform the paradigm of inclusive design and Housing in Portugal, into an increasingly tangible and accessible reality for everyone.

title	Damascus House: Exploring the connectionist embodiment of the Islamic environmental intelligence by design
doi	https://doi.org/10.52842/conf.ecaade.2023.2.871
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. 871–880
summary	Past studies have demonstrated that connectionist artificial intelligence (AI) has superior capabilities for style-based generative design because it automatically searches, extracts, and applies features according to the data-represented probabilistic profile of an architectural style. To further navigate its architectural affordance, this practice-led research project explores employing connectionist artificial intelligence to produce Islamic-style architectural forms that have historically revealed environmental intelligence by embedding sociocultural factors in response to the physical and human environmental design heritage. The project applies the Pix2Pix model and inverts the logic of some existing studies to predict the building plans from daylight maps. Use multi-objective optimisation algorithms to iteratively optimise factors such as building porosity, spatial quality, and microclimate, and use it as a condition to apply a Pix2Pix to generate a corresponding porosity model that is parametrised for the further design process. The model was trained on 120 augmented, paired images based on the 30 selected examples of Islamic architecture from the Damascus Atlas to capture the relationship between the massing distribution of walls and the arrangement of major elements in an Islamic courtyard house and its thermal performance. This study seeks to test if connectionist AI can be used as a generative design tool to understand the historical development of spatial relationships in Islamic courtyard houses. It focuses on non-repetitive style metrics, embedding physical and cultural factors into data representation. The resulting environmentally intelligent model adapts to the context, with optimisation being a pragmatic design guide rather than the ultimate goal. Although the inference is based on objective probabilistic facts, the influence of the informational framework interpreted by the designers must be acknowledged.

title	Game-based Platform for Daylight Analysis using Deep Learning
doi	https://doi.org/10.52842/conf.ecaade.2023.2.481
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 2, Graz, 20-22 September 2023, pp. 481–490
summary	Daylight analysis is not easy and requires skills in specific software and techniques and significant computation time. These skills are necessary for architecture education, but some students may find them challenging. For this reason, a software-free and simulation-free approach that quickly calculates daylight performance may be a more effective way for students to learn and practice architecture design. From these ideas, a game environment, which is familiar to the young generation, may enhance the excitement and engagement of education in this field. The development of a cubic builder game platform that utilizes the Deep Learning Model (DLM) to help users learn about daylight analysis within the game environment is currently underway. This paper presents the preliminary results of this study that focused on exploring methods for implementing and using DLM to predict daylight performance in a game environment. Using a drawing canvas, users can give design inputs in this environment. A framework involving three steps has been developed to combine data from the design and gaming environments. First, small-scale building models with specific design contexts and simulation data were created in Rhino and Grasshopper using LadyBugs and HoneyBee. Second, a DLM was trained on these data to make predictions. Last, developing the game environment with the well-trained DLM in Unity3D. Through analysis, the DLM's performance in game environments confirmed the potential of this approach. A building system will fully implement the game environment in future research. The DLM's predictive performance will be enhanced using more extensive and diverse data sets.

title	Mass-customisation of dwellings in the Middle East:developing a design-to-fabrication framework to resolve the housing crisis in Saudi Arabia
doi	https://doi.org/10.52842/conf.ecaade.2023.2.157
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 2, Graz, 20-22 September 2023, pp. 157–164
summary	The Saudi government is taking the initiative to modernise the country and address critical challenges. One of its primary goals is to relieve the housing deficit. One of the challenges in supplying the houses is that potential inhabitants have denied and refused to accept them due to their design failing to meet their demands. Furthermore, the government suffers from providing high-quality housing in line with people’s needs because only a few enterprises can meet the client’s needs, but only at the price of lengthy planning and building times, in addition to increased construction expenses. This research aims to propose a mass customisation design-to-fabrication workflow, which targets environmental optimisation, reduction of construction time and reduced cost and incorporates client involvement. Our research method includes conducting a survey with Saudi Arabian architecture firms to collect data about contemporary clients’ needs, analysing and reviewing mass-customisation tools & techniques, developing a bespoke algorithm capable of mass-customising housing and evaluating the algorithm through design experiments. Our findings present the advantages and challenges of our tool as well as a shape grammar of mass customised floor plan solutions.

title	A Critical Review on Research Themes and Trends in Green BIM for AEC Sector
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. 899-916.
summary	Green BIM is an emerging concept in the architecture, engineering, and construction industry that combines Building Information Modeling (BIM) technology with sustainable design principles. This approach emphasizes the importance of integrating green strategies into the design and construction process to improve the environmental performance of buildings. It enables designers, architects, engineers, and contractors to analyze the environmental impact of building materials and systems, simulate energy performance, and optimize the use of resources. The aim of the study is to conduct a bibliometric research and systematic analysis on the concept of 'green BIM'. Web of Science database was used to search for publications containing the term 'green BIM'. 252 relevant publications from the fields of construction building technology, architecture, and urban studies were analyzed. It evaluates research themes and trends in Green BIM in terms of publication and citation numbers, research areas, document types, journals, conferences, and books where publications were published, numbers of publications by country, author and co-authorship analysis, and keyword analysis. The keywords were divided into 9 clusters in the VOSviewer and each cluster was examined under a separate title. These titles are urban design, visual programming, design & construction, sustainability, energy efficiency, life cycle assessment, green BIM, project management and green building assessment. The results show that the most current keywords are being evaluated under the heading of urban studies. This situation highlights that, unlike other academic studies, priority is given to urban-scale applications of green BIM Moreover, apart from urban-scale studies, possible topics for academic research involve Life Cycle Assessment (LCA) and the integration of BIM in the LEED certification process. Currently, the industry and prominent publications prefer technical studies due to the extensive coverage of general inquiries.

title	AI-Integrated Urban Building Energy Simulation: A framework to forecast the morphological impact on daylight availability
doi	https://doi.org/10.52842/conf.ecaade.2023.2.369
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 2, Graz, 20-22 September 2023, pp. 369–378
summary	The research presents a computational framework to investigate the relationship between urban morphology and environmental performance metrics of buildings. Understanding how buildings interact with their surroundings is crucial in optimizing environmental performance. Current urban building energy simulation methods (UBES) often overlook the complex interaction between urban morphology and environmental performance across a diverse set of attributes, resulting in inaccuracies. The proposed framework integrates machine learning (ML) with physics-based simulations and includes Parametric Building Information Modeling, iterative physics-based simulations, Multi-Objective Optimization, and a graph neural network. The framework leverages the detailed analysis capabilities of physics-based simulations and the data processing strengths of ML to analyze urban morphological attributes. Evaluations indicate that the framework enhances prediction accuracy while considering the influence of urban morphology on environmental performance.

summary	The research presented in this paper focusses on the prefabrication of wood building systems using human craft and robotic machines as equal actors in collaborative fabrication processes. It uses self-developed components such as a data managing framework system to generate and exchange fabrication data between the design elements and the fabrication environment. Human robot collaboration via augmented reality (AR) technology is facilitated through a software framework and applied in the prefabrication of timber structures. Based on previous research, this iteration uses the concept of multi-actor fabrication and extends the number of human actors in the fabrication process. A case study was conducted for the collaborative fabrication of a timber structure. Five actors (four humans and one 7-axis robotic system) received instructions based on their individual skill set and collectively manufactured a timber structure in an organized workflow.

summary	Considering the architectural potential that emerges from the intersection of design principles and the evolving paradigms associated with increasingly integrated information modeling technologies, particularly in the context of computational design thinking, this research explores the concepts of shape grammar within the realm of Building Information Modeling (BIM). The primary focus of this work centers on exploring a design solution for an ephemeral, self-sustaining structure known as "camelódromo," with an inherent emphasis on the replicability of its elements. Notably, the research's significant contribution lies in applying this approach to a design process demanding the systematic consideration of variables for multicriteria decision-making. Beyond the process itself, this methodology provides more optimized solutions through alternative simulations, shedding light on previously unexplored possibilities.

summary	The microscopic universe represents a realm of intriguing possibilities, albeit one that remains largely unexplored. Promoting science through innovative approaches is vital, and the emergence of STEAM stands as a viable tool for that. Architecture, as a realm that directly impacts society, presents a unique potential to convey this new language, manifesting through building facades, walls, or urban furnishings. This study aims to unearth this potential by scrutinizing microscopic images and transposing this universe onto surfaces. The technique involves the 3D mapping of patterns extracted from micrographs and their application onto minimal surfaces. Through digital fabrication, the microcosmic and architectural realms converge within a transdisciplinary framework. This research underscores the feasibility to connect various knowledge domains, rendering them accessible to a broad audience, enabling microscopic imagery to explore, in novel contexts such as architectural ones, a playful and inclusive means of presentation.

title	Digital Structural Design for Natural Composites: A Case Study of Willow-Earth Hybrid Construction
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 282-292.
summary	As natural resources become increasingly scarce, it becomes crucial to seek solutions that promote circularity and sustainability. Embracing local materials and reinterpreting traditional architectural systems can help align the design of construction systems with these principles. Computational design methods can play a pivotal role in facilitating a transformative approach that supports the development of alternative material systems, their industrialization, and widespread adoption. This paper presents a computational design method for the structural development of a willow-earth composite construction system, aiming to advance the implementation of fully circular and waste-free building techniques through digital construction technologies. The research uses structural principles as a guiding factor for the development of the material system, and employs an integrative co-design approach to manage the reciprocal relationships between structural performance, material system behavior, and fabrication processes. By capitalizing on the advantageous interaction between willow and earth, a material system based on compres- sion-tension dualism is developed. This is achieved through digital studies of mechanical properties and computational analyses that inform the distribution, orientation, and gradation of the materials. The research incorporates feedback loops across multiple disciplines, both digital and analog, enabling a simultaneous consideration of the under- lying correlations. The research showcases the potential to expand the design possibilities for structures constructed with earth and willow composite materials. Through a distinc- tive digital workflow, it presents new avenues for sustainable and circular construction methods. The outcomes are illustrated through digital studies and a full-scale research demonstrator, providing tangible evidence of the research's advancements.

summary	Additive Manufacturing (AM) for large format building components is becoming popular. AM has allowed architects and engineers to rethink the process of manufacturing building components through lightweighting strategies associated with the processes of AM. AM allows just-in-time production of components which reduces the need for large storage space and minimizes the carbon footprint of the supply chain by bringing the production closer to the actual construction site. However, the feasibility and efficiency of large format fused filament fabrication (FFF) for large building components are still unclear. This paper presents a Computational Design for Additive Manufacturing (CDfAM) workflow of a doubly curved gyroid lattice wall as part of the research on the technological affordance of large format planar FFF for a doubly curved gyroid lattice wall and the feasibility of 3D printing without support structures.

summary	In this paper, we focus on the regeneration of the existing building stock coupled to the implementation of decarbonization policies. We propose a digital collaborative framework for the extension of buildings enabling a quick comparison of neighborhoods in the early design stages. The framework proposes the potential extendable roofs based on Geospatial information and a set of rules and further engineering analysis that are defined by the experts. The system selects the buildings that can host roof vertical extensions, with a first analysis of the expected Life Cycle Assessment (LCA) impacts based on previous LCA aggregated models.

title	A Novel Approach of Structural Modeling, Analysis and Optimization of Bearing Parts in Free-Formed Arc-Like Geometry Reconstructed from 4D Sketches
source	De Luca, F, Lykouras, I and Wurzer, G (eds.), Proceedings of the 9th eCAADe Regional International Symposium, TalTech, 15 - 16 June 2023, pp. 69–78
summary	Sketching is often used as the main approach in design of free-formed structures in very early stages of planning. Chosen materials for bearing and non-bearing parts and results of structural analysis can decisively affect the shape and form of planned geometry. The structural modelling, following finite element (FE) analysis and structural design can be very time-consuming due to still weakly regulated building information modelling (BIM) data exchange of free-formed structures. This paper describes a novel approach of structural modelling, analysis, and multi-objective optimization (MOO) of bearing elements of free-formed geometry sketched within a developed 4D semantic, mixed reality application MRSketch. The shapes of individual elements are computed from the recovered curve network and comprising boundary curves, aiming for smooth transitions and less deviation to the sketched strokes. The focus of this paper lays on the test case in which a free-form voluminous arc-like structure (similar to BUGA pavilion) has been thoroughly sketched in MRSketch. The computed geometry of the above-mentioned form is used for the structural analysis and MOO, whereby 3 different material and structure types are studied: monolithic concrete shell, plywood timber panels, and steel framework. The MOO process takes place with the goal of minimizing used material masses and de-flection of the structure. The ultimate and serviceability limit state´s (ULS and SLS) criteria acc. to Eurocodes represent MOO-constraints. Lastly, a large-scale estimate of the CO2 balance of the 3 above-mentioned construction´s variants is compiled and compared.

title	Mobilizing Publics - Reconsidering digital design as a catalyst in co-creation processes
doi	https://doi.org/10.52842/conf.ecaade.2023.1.671
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. 671–680
summary	Digital design has developed methods to address complex urban planning issues like the transformation of mobility using analytical tools and urban data. Simultaneously, such wicked problems require negotiation among involved stakeholders and situated knowledge. Even though contemporary City Digital Twin and urban data initiatives acknowledge this sociotechnical aspect (1&2), linking data analysis and participatory negotiations remains unresolved. In this paper, we bridge this gap by reconsidering digital design as a hybrid practice mediating between quantitative and qualitative approaches, between different stakeholders’ perspectives, and urban strategies (3). We explore this approach in the EU-funded New-European-Bauhaus initiative project “NEBourhoods”. Our action within this project addresses the mobility transformation of a car-centered late modernist housing estate in Munich. This initiative involves a digitally supported co-creation process, including a participatory platform, workshops, and two physical demonstrators for multifunctional mobility stations. Building upon earlier research in the context of design-decision support, collaborative design, and gamification, we discuss how these elements can be articulated as a hybrid strategy, mediating between heterogeneous aspects of urban mobility and different stakeholders’ perspectives. Firstly, we introduce spatial data analysis tools in participatory workshops with local experts and multipliers. Hence, the participants contextualize geospatial data and augment analytical data with situated knowledge. Successively we define possible locations and functions for the prototypical demonstrators. Consecutively we delve into these selected areas: Using a gamified mobile phone app, we gather information on local mobility practices and facilitate a co-creation process on the configuration of the demonstrators. Finally, the participatory app allows discussing and monitoring the implemented demonstrators and thus fosters a broader discussion on mobility transformation. In conclusion, we discuss how digital design assembles and mediates this strategy for mobility transformation. Thus, we focus on how digital tools gather and re-configure relevant perspectives, interactions, and elements in this hybrid co-creation process.

title	Conjugated Materiality – Reinstating Material Circularity via Digital Twins

summary	Industrial Revolution 4.0 offers an opportunity for the globe to rethink the meaning of building information that breaks the territorial borders of building information systems that are not based project-wise but follow a geopolitical structure. It expands the conventional thought process of being limited to a building to a city/ planetary urbanisation level. As a response to the new urban design theory, the paper posits an approach that amalgamates “Design for Disassembly (DFD)” and “Digital Twins” which have gained traction because of “Circular Economy” and “Industrial Revolution 4.0” respectively, to create an information framework for the urban ecology that focuses on system management rather than project management via “Material Passport (MP) 2.0”. It identifies the gaps within the existing MP and creates a foundational framework for the added information (termed “Material Strategies”) that needs to be a part of MP 2.0 that arise while working across systems by augmenting DFD and Digital Twins via the lens of materials. The material strategies are further investigated through a correlation matrix to understand their interdependency to finally create a JavaScript Object Notation (JSON)-based serialisation of materials to reinstate the material circularity and reduce the carbon emissions that the construction sector accounts for.

summary	Increasing interest in living materials has pushed scientists and designers to explore the potential of fungi, algae, yeast, and bacteria as part of the fabrication process. The microbially-produced biopolymer, bacterial cellulose (BC), shows great potential as an alternative building material due to its high durability, tensile strength, moisture resistance, and lightweight nature. Current BC fabrication methods primarily involve post-processing the naturally forming flat material after its growth phase. This research investigates an approach into co-designing with cellulose-producing bacteria to explore its morphogenetic tendencies in order to create intricate 3-dimensional forms. This paper looks at a fabrication approach that diverges from conventional BC material production towards form-finding by creating explorative methods that guide BC formation through the control of airflow. We present an experimental workflow with a bacteria and yeast that employs a strategy to identify parameters for guiding the morphological development of BC. To capture the form of the delicate material samples, a multi-step preservation process was developed, providing data on both the external and internal structure of the material. Photographic documentation of the growth process enabled the categorization of bacterial behavior in response to distinct environmental stimuli. Based on these obser- vations, a set of design principles was established to allow us to predict the morphological development of BC growth within a bioreactor. These experiments address a new type of unconventional computational approach to form-finding by studying the native growth mechanism of living bacteria, and offering a new perspective on our design engagement with these processes.

title	Autonomous Collaborative: Robotic Reconfiguration with Deep Multi-Agent Reinforcement Learning (ACRR+DMARL)

summary	To address the unprecedented challenges of the global climate and housing crises, requires a radical change in the way we conceive, plan, and construct buildings, from static continuous objects to adaptive eco-systems of reconfigurable parts. Living systems in nature demonstrate extraordinary scalable efficiencies in adaptive construction with simple flexible parts made from sustainable materials. The interdisciplinary field of collec- tive robotic construction (CRC) inspired by natural builders has begun to demonstrate potential for scalable, adaptive, resilient, and low-cost solutions for building construc- tion with simple robots. Yet, to explore the opportunities inspired by natural systems, CRC systems must be developed utilizing artificial intelligence for collaborative and adaptive construction, which has yet to be explored. Autonomous Collaborative Robotic Reconfiguration (ACRR) is a robotic material system with an adaptive lifecycle trained with deep, multi-agent reinforcement learning (DMARL) for collaborative reconfigura- tion. Autonomous Collaborative Robotic Reconfiguration is implemented through three interrelated components codesigned in relation to each other: 1) a reconfigurable robotic material system; 2) a cyber-physical simulation, sensing, and control system; and 3) a framework for collaborative robotic intelligence with DMARL. The integration of the CRC system with bidirectional cyber-physical control and collaborative intelligence enables ACRR to operate as a scalable and adaptive architectural eco-system. It has the potential not only to transform how we design and build architecture, but to fundamentally change our relationship to the built environment moving from automated toward autonomous construction.

title	An Integrated Method for the Mesh Representation and Segmentation of Kagome Weaving Geometries
doi	https://doi.org/10.52842/conf.ecaade.2023.1.599

summary	This research presents an integrated method for the mesh representation, and also segmentation methods of Kagome Weaving Geometries. "Kagome Weaving" refers to a traditional bamboo weaving technique where triaxial strips are interlocked to create a stable structure. However, the traditional techniques heavily rely on inherited knowledge and experience, and the complexity of the weaving process, coupled with the length limitation of bamboo, restrict its application as diverse architectural elements. The limitations also hinder the exploration of sustainability through design. To address these challenges, this research combines traditional weaving processes with computational design tools, developing a strip representation algorithm that incorporates characteristics of fabrication processes and mesh segmentation method. This integrated design process enables the exploration of fabricable geometry information for weaving at an architectural scale beyond the limitations imposed by the length of bamboo, especially during the digital prototyping stage. Moreover, it allows designers to focus on exploring various forms. Additionally, we have developed indicators for fabricable geometry information assess material efficiency and construct curvature characteristics. This study can be applied to non-structural elements in architecture, such as building facades, interior design, frames, and templates, providing designers with more efficient and feasible methods.
