title	Light Transmittance Ceramic Design-Computation with Robotics
source	Herrera, PC, Dreifuss-Serrano, C, Gómez, P, Arris-Calderon, LF, Critical Appropriations - Proceedings of the XXVI Conference of the Iberoamerican Society of Digital Graphics (SIGraDi 2022), Universidad Peruana de Ciencias Aplicadas, Lima, 7-11 November 2022 , pp. 515–526
summary	Building envelope design incorporates a range of light-related analyses, often providing an essential feedback loop for shaping an envelope’s performance, geometry, or components. This is true for solar radiation studies of envelopes, calculated irrespective of building material or assembly. Extending our light-related analysis to include diffuse lighting effects on a building interior presents an opportunity to explore the translucency, porosity, and forms of materials. Glazed architectural ceramic components fabricated using adaptive robotic manufacturing provide an opportunity to exploit material dynamics within the design and alleviate fabrication waste from molds, ultimately accelerating the production manufacturing system. In addition to analyzing the solar radiation on the building facade design, lighting effects can be engaged in profoundly different ways depending on the degree of design-production agency. The production process can be extended beyond automatic routines using robotic fabrication with levels of autonomous involvement that allow for alternative form expressions of the dynamic clay material. In addition to negotiating several design criteria, the design research will develop an aesthetic character originating from customized clay materials and robotic manufacturing processes for lighting transmittance architectural ceramics.

summary	Recently, as more and more projects on residential environment improvement in cities are actively carried out, the cases of demolishing or remodelling buildings has been increasing. Most of the target buildings for such projects are made of concrete. In order to reduce energy use as well as carbon emissions, the amount of concrete used as a building material should be reduced. This is because the concrete is the largest amount of construction waste, which the exact amount of concrete needs to be predicted. The architectural drawings are essential for the estimation and demolition of building waste, but the problem is that most of the old buildings' drawings do not exist. The 3D scanning process was performed to create the plans for such old buildings instead of the conventional method that is long time-consuming and labour-intensive actual measurement. In this study, we scanned 40 old houses that were scheduled to be demolished. The result showed that the 3D scanned drawings' accuracy - 99.2% - was higher than the ones measured by the conventional way. Through the algorithm developed in this study, the various processes of demolition, drawing measurement, and discarding quantity prediction can be solved in one process, thereby reducing work efficiently. And, considering the reliability of the research results, it is possible to reduce the economic loss by predicting the exact amount of waste in advance. After that, if the algorithm, developed in this study, can be further subdivided and supplemented to identify the materials for each part of the old buildings, it will be able to propose an efficient series of processes that distinguish between recyclable materials and wastes and thereby efficiently dispose of them. 0864108000

title	Felt and Fold - Design and manufacturing of customized nonwovens through robotic needle felting

doi	https://doi.org/10.52842/conf.ecaade.2022.1.195
summary	This paper explores the potential of robotic needle felting for customized production of nonwoven textiles and their architectural applications. The possibility to program the robotic movement and locally control fiber density and distribution allows the design of nonwoven, heterogeneous materials with graded properties not by differentiating their chemical composition, but rather controlling their mechanical structure. We propose a parametric design and fabrication workflow relying on a 6-axis robotic arm. We describe design techniques for the generation of felted surfaces with varying material properties and their translation to instructions for robotic felting, as well as the physical fabrication setup. Within our research, the ability to locally differentiate material properties is further explored to create three-dimensional folding behaviors. We study how fiber densities affect their folding ability and geometry, examine qualities of resulting edges, analyze how they affect folding and finally design targeted folded structures by informing the felting pattern. While robotic felting has not yet found significant applications in architecture, the designs and prototypes demonstrate its potential in the architectural context, as it suggests new solutions for recyclable, circular building components or surfaces.

title	Fuzzy 3D Fabrics & Precise 3D Printing - Combining research with design-build investigations

summary	We present a synergetic combination of two previously separate process technologies to create novel lightweight structures. 3D textiles and 3D printing. We will outline the development of a novel material system that consisted of flexible and foldable 3D textiles that are combined with stiff, linear 3D printed materials. Our aim is to produce material-reduced lightweight elements for building applications with an extended functionality and recyclability. Within an ongoing research project (6dTEX), we explore a mono-material system, which uses the same base materials for both the filament for 3D printing and the yarn of the fabrication of the 3D textiles. Based on preliminary 3D printing tests on flat textiles key process parameters were identified. Expertise has been established for 3D printing on textiles as well as for using printable recycled polyester materials (PES textile and PETG filament. Lastly for 3D printing on non-combustible material (alkali-resistant (AR) glass textiles and for 3D concrete printing (3DCP). The described process- knowledge facilitates textile architectures with an extended vocabulary, ranging from flat to single curved and folded topologies. Whereas the foundations are laid in the research project on a meso scale, we also extended our explorations into an architectural macro scale. For this, we used a more speculative design-build studio that was based on a more loose combination of 3D textiles and 3D printed elements. Lastly, we will discuss, how this first architectural application beneficially informed the research project.

summary	The need for increased automation of the AEC sector has been extensively documented within the architectural discipline over recent years. Far beyond economic perspectives, current advances in technology offer an increased and more direct implementation of sustainable materials. Within this research, the potential for the re-use of material with low embodied energy within automated construction will be examined. Herefore, Remote Material Deposition (RDM, firstly described in Dörfler et al., 2014) is utilized as main fabrication method, deploying varying compositions of local building debris, lime mortar, and sand, via a throwing arm. This research explores a method of continuous verification of material deployment and removal of material oversaturation to guarantee accuracy. Herefore, all instances of the robot ecology are in direct communication with one another and the user for verification, adaptation, and information. The proposed framework is examined through experimentation by designing, building, and implementing an inter-communicative network of bespoke semi-autonomous robots with all proposed parts of the system.

title	Reconfigurable Formwork System for Vision-Informed Conformal Robotic 3D Printing
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. 387–396

summary	Robotic additive manufacturing has garnered significant research and development interest due to its transformative potential in architecture, engineering, and construction as a cost-effective, material-efficient, and energy-saving fabrication method. However, despite its potential, conventional approaches heavily depend on meticulously optimized work environments, as robotic arms possess limited information regarding their immediate surroundings (Bechthold, 2010; Bechthold & King, 2013). Furthermore, such approaches are often restricted to planar build surfaces and slicing algorithms due to computational and physical practicality, which consequently limits the feasibility of robotic solutions in scenarios involving complex geometries and materials. Building on previous work (Çapunaman et al., 2022), this research investigates conformal 3D printing of clay using a 6 degrees-of-freedom robot arm and a vision-based sensing framework on parametrically reconfigurable tensile hyperbolic paraboloid (hypar) formwork. In this paper, we present the implementation details of the formwork system, share findings from preliminary testing of the proposed workflow, and demonstrate application feasibility through a design exercise that aims to fabricate unique components for a poly-hypar surface structure. The formwork system also offers parametric control over generating complex, non-planar tensile surfaces to be printed on. Within the scope of this workflow, the vision-based sensing framework is employed to generate a digital twin informing iterative tuning of the formwork geometry and conformal toolpath planning on scanned geometries. Additionally, we utilized the augmented fabrication framework to observe and analyze deformations in the printed clay body that occurs during air drying. The proposed workflow, in conjunction with the vision-based sensing framework and the reconfigurable formwork, aims to minimize time and material waste in custom formwork fabrication and printing support materials for complex geometric panels and shell structures.

title	Non-Standard Robotic 3D Printing for Architects - A comprehensive digital fabrication lab pedagogy integrating non-programmable material effects
source	Pak, B, Wurzer, G and Stouffs, R (eds.), Co-creating the Future: Inclusion in and through Design - Proceedings of the 40th Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2022) - Volume 1, Ghent, 13-16 September 2022, pp. 19–28
doi	https://doi.org/10.52842/conf.ecaade.2022.1.019
summary	The study presents a pedagogical framework familiarizing architecture students with explorations of non-programmable material effects through non-standard robotic 3D printing. The purpose of integrating such explorations in education is to train architects- to-be in embracing the challenges related to working close with architectural materials and production, requiring new stances toward the dichotomies between drawing and building, material agency and error as well as precision and lack of full control over the design outcome. The framework was evaluated in an architectural course on artistic robotic 3D printing. The results show that it achieves the aim of supporting students in addressing, in an informed and creative manner, the uncertainties of digitally aided materialization. The students explored refined material effects while acquiring practical digital manufacturing skills and critically engaging with theories and discourses on new materiality and non-standard production. Hence, the proposed pedagogy can be employed to complement the current education curricula, providing architecture students with a broader outlook necessary for fully embracing opportunities and challenges at the crossing between new materials and digital production.

title	Democratizing Stereotomic Construction through AR Technologies - A reusable mold methodology to the production of customized voussoirs using HoloLens
source	Pak, B, Wurzer, G and Stouffs, R (eds.), Co-creating the Future: Inclusion in and through Design - Proceedings of the 40th Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2022) - Volume 1, Ghent, 13-16 September 2022, pp. 225–232

summary	Mass customizing of building components allows new conditions to explore aesthetic and sustainability in architecture. However, such possibilities tend to require the use of expensive and heavy digital fabrication machinery, which is seldomly available in most regions on the planet. In this context, this paper presents a research in progress that explores Augmented Reality (AR) to support craft production of customized stereotomic components. As a portable technology, the work examines the potential of AR to materialize design solutions that are geometrically complex and variable. Considering the current research on augmented fabrication processes, this work contributes to producing variable building components for stereotomic construction with a focus on earth-based materials. Extending the findings of a recently completed PhD thesis, the work replaces the use of a robot with the HoloLens glasses and Fologram application to produce low- cost and reusable molds. This augmented fabrication setup allows the human control of the production of variable molds, ready for casting and assembly of stereotomic components. This work addresses several of the NEB and UN SDGs goals.

doi	https://doi.org/10.52842/conf.ecaade.2022.2.437
summary	The new construction that is projected to take place between 2020 and 2040 plays a critical role in embodied carbon emissions. The change in material selection is inversely proportional to the budget as the project progresses. Given the fact that early-stage design processes often do not include environmental performance metrics, there is an opportunity to investigate a toolset that enables early-stage design processes to integrate this type of analysis into the preferred workflow of concept designers. The value here is that early-stage environmental feedback can inform the crucial decisions that are made in the beginning, giving a greater chance for a building with better environmental performance in terms of its life cycle. This paper presents the development of a tool called LearnCarbon, as a plugin of Rhino3d, used to educate architects and engineers in the early stages about the environmental impact of their design. It facilitates two neural networks trained with the Embodied Carbon Benchmark Study by Carbon Leadership Forum, which learns the relationship between building geometry, typology, and construction type with the Global Warming potential (GWP) in tons of C02 equivalent (tCO2e). The first one, a regression model, can predict the GWP based on the massing model of a building, along with information about typology and location. The second one, a classification model, predicts the construction type given a massing model and target GWP. LearnCarbon can help improve the building life cycle impact significantly through early predictions of the structure’s material and can be used as a tool for facilitating sustainable discussions between the architect and the client.

title	Encoding topological optimisation logical structure rules into multi-agent system for architectural design and robotic fabrication
source	International Journal of Architectural Computing 2022, Vol. 20 - no. 1, pp. 7–17
summary	Natural phenomena have been explored as a source of architectural and structural design inspiration with different approaches undertaken within architecture and engineering. The research proposes a connection between two dichotomous principles: architectural complexity and structural efficiency through a hybrid of natural phenomena, topology optimisation and generative design. Both Bi-directional Evolutionary Structural Optimisation (BESO) and multi-agent algorithms are emerging technologies developed into new approaches that transform architectural and structural design, respectively, from the logic of topology optimisation and swarm intelligence. This research aims to explore a structural behaviour feedback loop in designing intricate functional forms through encoding BESO logical structure rules into the multi-agent algorithm. This research intends to study and evaluate the application of topology optimisation and multi-agent system in form-finding and later robotic fabrication through a series of prototypes. It reveals a supposition that the structural behaviour-based design method matches the beauty and function of natural appearance and structure. Thus, a new exploration of architectural design and fabrication strategy is introduced, which benefits the collab- oration among architects, engineers and manufacturers. There is the potential to seek the ornamental complexities in architectural forms and the most efficient use of material based on structural performance in the process of generating complex geometry of the building and its various elements.

title	Reimagining Gego: Geometrical Reconstruction of Nubes, an Undocumented and Lost Sculpture from 1974

doi	https://doi.org/10.52842/conf.ecaade.2022.2.217
summary	This paper describes a method to understand and digitally reconstruct two sculptures by Gertrud Goldschmidt, a German-born, Venezuelan artist also called Gego. Gego is best known for her series of works called “Reticuláres”. These three-dimensional and open installations, mostly hanging freely in space, are playing with the concept and perception of space as well as challenging the definition of the traditional sculpture. The paper aims to generate information about two specific structures called “Nubes” (Clouds for Spanish) to assist in a physical reconstruction for a larger exhibition about Gego and to contribute to understanding Gego’s work process. Originally, the structures were suspended from a building's ceiling as an art installation in Caracas, 1974. There are three main challenges for this reconstruction: (1) The installations exhibit a complex three-dimensional geometry. (2) Scant drawings and photographs exist. (3) Gego might not have followed her initial drawings completely when building Nubes physically, because of the mentioned complexity and due to the light and bendable material properties of the employed material. The paper describes a computational process that recreates the object’s geometry in four steps: (1) Analyse all existing media of the structure. (2) Translate found information to the digital environment of Grasshopper. (3) Use a physical simulation to derive the end state of the hanging structure. (4) Optimize and tune the simulation with an optimization algorithm for better results. This paper demonstrates the usefulness of computational tools for reconstructing lost sculptures with little documentation. In this case, these tools allow a more accurate reconstruction and contribute to a fuller understanding of the design and realization process of Gego's Nubes.

title	Is Language All We Need? A Query Into Architectural Semantics Using a Multimodal Generative Workflow

doi	https://doi.org/10.52842/conf.caadria.2022.1.353
summary	This project examines how interconnected artificial intelligence (AI)-assisted workflows can address the limitations of current language-based models and streamline machine-vision related tasks for architectural design. A precise relationship between text and visual feature representation is problematic and can lead to "ambiguity‚ in the interpretation of the morphological/tectonic complexity of a building. Textual representation of a design concept only addresses spatial complexity in a reductionist way, since the outcome of the design process is co-dependent on multiple interrelated systems, according to systems theory (Alexander 1968). We propose herewith a process of feature disentanglement (using low level features, i.e., composition) within an interconnected generative adversarial networks (GANs) workflow. The insertion of natural language models within the proposed workflow can help mitigate the semantic distance between different domains and guide the encoding of semantic information throughout a domain transfer process.

summary	This research explores the constructive and expressive capabilities of stigmergic-based creasing patterns integrating structural and ornamental conditions in fibre-composite surface tectonics, generated by the reciprocal influence of multi-agent systems and Non- Linear Time History (NLHT) dynamic structural simulation. Building upon precedents on the use of agent bodies and behavioural tectonics such as the work of Roland Snooks, our approach employs NLTH simulation for the dynamical assessment of the structural failure modes to provide information for agents behaviour and a comparative assessment of the bodies pattern contribution. Considering the obtained results, insights gained on the structural behaviour of multi-agent composite surface tectonics while attempting to explore its embedded architectural, morphological and expressive qualities are discussed.

summary	Graph-based representations of functional requirements (adjacencies, bubble diagram) are a common and useful method that supports architects in the conceptual phase of planning. However, the task of specifying the functional requirements through an adjacency graph can be challenging due to a quadratic growth of complexity in relation to the number of spaces. In turn, this increase of complexity challenges the designer searching for solutions that fulfill these functional requirements. There are systems that aim to address the difficulties related to graph-based space allocation. They, for instance, use fuzzy logic to weight the edges of a graph (i.e., specify relations between spaces) and spring systems (Newtonian gravitation model) to visually clarify the resulting proximity of all spaces according to the rules. Nevertheless, the problem of specifying large-scale adjacencies itself is omitted due to the assumption that such matrices are correctly filled in some previous steps. Moreover, the translation of the resulting graph into a spatial configuration is rarely supported. This work addresses these limitations and proposes a set of tools to assist the designer when defining the adjacency requirements and searching for design solutions that fulfill these requirements. Our approach aims to reduce the complexity of the design task by using graph centrality-based design heuristics. We discuss these heuristics and show their application in a scenario where a new spatial program needs to be allocated into an existing building.

summary	Gypsum is one of the most commonly used construction materials in cladding and non-load-bearing decoration. Recently, 3D printing technology has been involved in creating complex geometry. The particle-based method is the principal approach in 3D gypsum printing. However, the complex device and limited printable range limit the massive production of large-scale building components. This paper proposed a novel extrusion-based gypsum printing method and corresponding robotic fabrication workflow. First, several experiments are conducted to analyze the effect of different admixtures (retarder, activation agent, and accelerator) on the material setting properties. Second, a set-on-demand gypsum-based material is proposed by actively controlling multiple admixtures. Then, a process parameter-based robotic fabrication workflow is proposed, and a set of extrusion- based 3D gypsum printing equipment is built. center864108000A curved gypsum panel sample is printed as experimental verification. By comparing to the particle-based method, The test sample shows that the extrusion-based method can effectively improve the production efficiency and reduce the production cost. Therefore, the proposed method gives a relatively efficient and cost-effective way to produce recyclable gypsum material massively.

title	Fabricating lightweight ceramics by spraying clay on knitted structures
source	International Journal of Architectural Computing 2022, Vol. 20 - no. 4, pp. 693–706
summary	This research was carried out to develop a novel composite material consisting of a thread reinforcement and a clay matrix, as well as to develop a method of shaping this material into hollow spatial structures. Ceramic elements in the building industry are currently created by applying extruding, pressing and casting methods. The approach of spraying clay onto predefined knitted meshes increases the usability of digitally fabricated lightweight ceramic elements, while eliminating the need for scaffolding. In this approach, multiple layers of a fluid clay mass are sprayed onto the tensioned mesh using an industrial, six-axis robotic arm. This allows the precise application of the material and results in varying material thicknesses. Due to the complementary qualities of clay which absorbs compressive forces and threads which absorb tensile forces, lightweight structures can be created. The research involved experimenting with clay mixtures, several thread types, knitting methods and spraying techniques, as well as fabricating a 1:1 lightweight module as an architectural prototype.

summary	This research presents the development of a construction system for a solid expanded cork building envelope. The inspiration for this research is the “Cork House” built in 2019 by Matthew Barnett Howland and Oliver Wilton, who developed a Cork Construction Kit for a monolithic dry-jointed cork structure. The goal of this research is to analyze and develop different varieties of construction methods for a dry-joined cork building by combining and applying traditional masonry techniques. The objective is to generate a material-based design for cork construction elements trough prototyping and using a selection of digital tools such as 3D modeling and 3D printing. Expanded cork is a 100% plant-based material which, if applied correctly, has the capacity to be used as a load bearing, insulating and protective structure all at once. It has almost no environmental impact and is completely compostable. To maintain the material's compostable property, this construction system has to be developed without any kind of binders or mortar. Additionally, this more reduced and simplified form of construction will not only make it possible to build without any specific expertise, but at the same time ensure resources to be reused or composted at the end of building life.

title	Parametric Skin Design Method Based on Plane Crystallographic Group Operation Principle

summary	Under the dual constraints of industrialization and digitalization, the building skin and structure are further integrated to form standardized units to meet the requirements of architectural performance, industrial prefabrication and “complexity” aesthetic characteristics. The complex and diverse forms of today's building skin hide profound mathematical logic relations and operation rules of form generation. Crystallographic group with regular symmetry and the operation principles reflected by it is one of the most important rules and methods of form and pattern processing in skin design. The study of the mural symbols in ancient Egypt, the murals in the Alhambra, the manuscripts of Escher and the window lattice in ancient Chinese architecture profoundly reflects the basic operation principle of crystal group in shaping the skin form of architecture. Abundant and diverse architectural skin forms can be formed through the operation of symmetry group on basic graphic units. On the basis of clarifying the basic principle of crystal group action, the operation matrix of crystallographic symmetry group can be transformed into parameterized operation steps through programming language for visual operation, and then the skin form with high complexity and leap dimension can be generated by geometric algorithm, and the design method of building skin generation based on crystallographic group is constructed. In the selection of operation form, combined with the calculation of building performance and structure, the construction skin can be used in practical engineering is generated. Based on crystallographic group operation, the unifications of building skin and the classification simplification of components can meet the requirements of modular and unifications design in the process of building industrialization, and meet the requirements of current building industrialization and digitization. It has great research significance and value in the aspects of design and construction efficiency and material economic cost.

title	Adapting Digital Architecture Vocabulary to Reformulate Geometric Compositions of Islamic Facades - Case Study: Proposed Model for Islamic Façade through Digital Vocabulary
source	Hybrid Spaces of the Metaverse - Architecture in the Age of the Metaverse: Opportunities and Potentials [10th ASCAAD Conference Proceedings] Debbieh (Lebanon) [Virtual Conference] 12-13 October 2022, pp. 463-483
summary	Islamic architectural facades characterized by many distinguished vocabularies that formed its character; as arches, ornaments, al-Muqarnas and mashrabeya etc. However, during the modern era, the Islamic heritage regions faced many changes and transformations of its character, either by new buildings that were built according to modern or unplanned styles, or by random and unplanned developments. However, recently and with the beginning of the twenty first century and with the great breakthrough in the digital tools and techniques, it facilitates new horizons in the architectural form generation. Accordingly, the research focuses on how to investigate the positive impacts of digital technologies on Islamic Architecture. In addition to how to utilize the digital thoughts, vocabulary, and techniques to create and develop a heritage inspired vocabulary that can compromise with the traditional Islamic architecture theme. Through this, the research aims to achieve a systemization of digital design strategies to facilitate the generation of Islamic-inspired façade, to create a new Islamic architecture that can be applied within Islamic heritage regions to connect the modern buildings which located in these regions with the existing Islamic reference. To achieve that, the research starts with studying and discussing the main elements that formed the Islamic facades, to stand on the methods of formations of each element and its function of the Islamic façade, whether it is an intrinsic function or aesthetic function. Consequently, standing on the main digital theories that lead to new architectural vocabulary that can homogenate with Islamic vocabulary, through studying the concept of each digital theory, accordingly how it can be applied theoretically to create a modern façade with an Islamic spirit. The research ends with a case study for a proposed modern building that resembles most of the recent buildings in Al-Azhar Islamic region in Cairo, and how through applying some selected digital theories can result in developing and renovating this facade to match the heritage Islamic surrounding in a new digital way.

summary	The InterACT research project focuses on the use of computational design and manufacturing methods in the construction of self-build projects based on wooden structures. The goal is the interdisciplinary development and realization of a prototypical laboratory on the university campus in Cologne. At the intersection of craftsmanship and architecture, the project aims to generate, collect and share interdisciplinary knowledge. The InterACT Lab is intended to function as a hybrid learning and research space, uniting theory and practice. Moreover, the project should make the concept of networked learning and research visible beyond the academic boundaries. The entire development of the project has been set-up as a participative and collaborative learning process, involving students in the conceptual design, decision making and the production of the building components as well as in the assembly of the structure, using digital tools as a common base and connector throughout the process. The paper presents the didactic concept and discusses the findings of the various steps from the early design phase to the realization of a first prototype in scale 1:1.
