summary	The project develops pre- and post-demolition digital assessment protocols in order to better inform reclaimed material implementation in new projects. The application of the protocols are demonstrated in a pavilion constructed of reused timber (Figure 1). By facilitating the data capture, analysis, identification, and characterization of available secondary raw materials, and creating database systems for pre- and post-demolition sites, it promotes gains in high quality upcycled materials for new construction projects. Modern reality capture technologies allow for collecting high density and quality Construction and Demolition Waste (CDW) data, presenting the opportunity to also increase the reliability and trust in upcycled materials by data specifically structured to relevant actors.

title	The Impacts of Collaboration and Cordination of Architectural and Engineering Projects Developed with BIM in Reducing Design Interferences
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 783–794
summary	This paper addresses the importance and development of cultural transformations involving the design process in architecture and the advent of Building Information Modeling (BIM) in civil construction activities and how its implementation in a coordinated, collaborative and interoperable way contributes to a diagnosis of Clash Detection between diferentes design projects, before building construction, saving excessive costs and rework. Taking as its main reference the BIM Maturity Matrix of Succar (2009), the proposed BIM Project Integration Maturity Matrix contributes to the awareness of bringing designers and builders closer to design activities, to encourage the integration of design processes involving the building, to consolidate an environment of ease of communication between participants, the organization of documentation and, above all, prioritize the compatibility between projects to avoid conflicts, excess costs and rework, resulting in a higher quality of the final project.

title	Immersive Variations: Connecting Architectural Sensitivity with Parametric Design through Collaborative Virtual Reality Environments
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 1017–1028
summary	Undergraduate design studies for digital fabrication and non-standard architecture are complex as their participants are usually far from systems thinking and have a basic level of confidence in the use of advanced digital tools. Furthermore, in the face of high formal complexity, the understanding of the structural system and its effects for the inhabitant are not evident. This work presents an implementation of Virtual Reality to introduce Latin American architecture university students to digital fabrication and parametric design, taking as its main premise that during the initial design stage, the designed architecture using virtual reality techniques and spatial perception can engage students to appreciate the value in these new designs, formulating new arguments and paradigms to further contribute to their training as contemporary professionals.

title	The Biomimicry Design Lens Method Applied to the Development of a Temporary Pavilion Inspired by the Victoria Amazonica
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 1423–1434
summary	Combining Biomimicry and Parametric Design, this research aims to detail the design process of an ephemeral pavilion which uses the method Biomimicry Design Lens, proposed by Biomimicry 3.8. The experiments developed in this paper followed the method’s diagram insights and it was guided by the ‘Biology for Design’ diagram in a non-sequential order in the design process. The pavilion is located in the Serpentine Gallery, and it was bio-inspired by the ribs of the inferior face of the Victoria amazonica leaf, a natural morphological structure that was translated into a quadrangular grid characteristic of the waffle structure. Finally, the parametric implementation allowed the development of several morphological experiments.

summary	This research demonstrates the development of a hybrid FRP-timber wall and slab system for multi-story structures. Bespoke computational tools and robotic fabrication processes allow for adaptive placement of material according to specific local requirements of the structure thus representing a resource-efficient alternative to established modes of construction. This constitutes a departure from pre-digital, material-intensive building methods, based on isotropic materials towards genuinely digital building systems using lightweight, hybrid composite elements. Design and fabrication methods build upon previous research on lightweight fiber structures conducted at the University of Stuttgart and expand it towards inhabitable, multi-story building systems. Interdisciplinary design collaboration based on reciprocal computational feedback allows for the concurrent consideration of architectural, structural, fabrication and material constraints. The robotic coreless filament winding process only uses minimal, modular formwork and allows for the efficient production of morphologically differentiated building components. The research results were demonstrated through Maison Fibre, developed for the 17th Architecture Biennale in Venice. Situated at the Venice Arsenale, the installation is composed of 30 plate like elements and depicts a modular, further extensible scheme. While this first implementation of a hybrid multi-story building system relies on established glass and carbon fiber composites, the methods can be extended towards a wider range of materials ranging from ultra-high-performance mineral fiber systems to renewable natural fibers.

title	Affective Cartographies for Smarter Cities
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 1295–1306
summary	This paper focuses on the study of affective and digital cartographies and on relating them systematically with their design applications. The research is based on the Design Science Research strategy, through the following logical structure: (1) Problem identification; (2) Communication; (3) Definition of the objective of the solution; (4) Artifact design, development and implementation; (5) Demonstration and Evaluation. The results presented correspond to phases (1), (2) and structuring of (3). The categorization was based on the principles: (a) dynamism (dynamic vs. static), (b) responsiveness (immediate vs. non-immediate), (c) implementation domain (hard vs. soft), and (d) affective aspect (quantitative vs. qualitative). This was synthesized in a chart, which was submitted to the analysis of a group of 4 experts from a public urban planning entity, and possible applications of affective cartographies in urban projects were obtained. Those were confronted with reality from the overlapping of the problems listed with the synthesis chart, positioning such cartographies as to their vocations.

title	A Shape Grammar Implementation: The Case of Fishing Villages in Santa Catarina
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 725–736
summary	The fishing villages of the Santa Catarina state, in Southern Brazil, have been suffering from a process of transformation that accompanies the replacement of the activities related to artisanal fishing in order to insert the dynamics of tourism. Aiming to preserve the underlying logic responsible for generating these self-built settlements, a shape grammar was elaborated and implemented in a visual programming environment to test its efficiency in reproducing the compositional language of the villages. The method involved the historical context and constructive typologies analysis, which made it possible to extract the corresponding rules regarding the spatial configuration of the corpus. The result emerged as a descriptive grammar, which later was implemented in a parametric modeling environment, algorithms in C# were used to generate the compositions with the aid of computational strategies based on random numbers, stochastic research and object-oriented programming.

title	Reuse of Ceramic Roof Tiles: Enhancing New Functional Design Possibilities Through the Integration of Digital Tools for Simulation, Manufacture and Assembly
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 1475–1486
summary	The material qualities of ceramic roof tiles have provided new formal interpretations that induced a new functional use—a wall. By disassembling ceramic roof tiles from roofs and assembling them into walls, its circularity potential was enlarged. This paper explores the potential use of ceramic roof tiles, as a single element type, in the definition of wall design systems and patterns of composition that comply with design for manufacture, assembly and disassembly (DfMA-D) requirements, through the development of a shape grammar and implementation through parametric models. The new shape grammar extends the compositional patterns already produced and the redefinition of the connection systems by incorporating DfMA-D requirements into the shape grammar rules sets new combinatorial patterns aligned with European Union goals for building circularity. The parametric models automate the generation of design solutions and extend the design process to the assembly and disassembly stages using robotic fabrication techniques.

title	The Digital Design Build - Modes of Experiential Learning in the Pandemic Era
source	A. Globa, J. van Ameijde, A. Fingrut, N. Kim, T.T.S. Lo (eds.), PROJECTIONS - Proceedings of the 26th CAADRIA Conference - Volume 2, The Chinese University of Hong Kong and Online, Hong Kong, 29 March - 1 April 2021, pp. 41-50

summary	In recent years, academia has deviated from the lecture-based model to a hybridized system of instruction and experiential learning. Experiential learning aids students in understanding collaborative processes in architectural praxis and exposes them to engaging learning opportunities, a critical component of architectural studio education (Nijholt et al. 2013). During the COVID-19 outbreak, students are barred from accessing on-campus facilities. This causes a redevelopment of curricular delivery and disrupts experiential learning which heavily relies on in-person interaction. It is imperative for instructors to retain experiential learning in the transition to virtual instruction. This paper explores experiential learning within virtual platforms for instruction. Through outlining the implementation of technologies, capitalizing on connectivity, and maximizing opportunity for digital problem solving, the authors posit a framework that other educators may adopt. The paper concludes with a case study of a virtual design-build project, and the various techniques implemented in retaining experiential learning during the pandemic.

summary	This paper will propose the integration of multi-view stereo and time of flight technologies and components. Through the spatial point cloud sensor, the changes of objects in the space are converted into digital point clouds, which are feedback on the virtual interface. To make the virtual and physical will continuously communicate and feedback in space, which we established a correction tool for the integration of virtual and physical. The agent-based sensor computing method combines the fabrication process of visual sensors and behavior, from virtual object control to fabrication machines. In this tool, users can explain the reasons for design decisions by visualizing process and process-related information. It allows virtual and physical previews and feedback in real time, and finds out the differences between the two and makes real-time corrections. Solved the correction problem of coexistence.

summary	Augmented Reality (AR) has the potential to create a paradigm shift in the production of architecture. This paper discusses the assembly and evaluation of a bamboo prototype installation aided by holographic instructions. The case study is situated within the framework of AR-driven computational design implementation methods that incorporate feedback loops between the as-built and the digital model. The prototype construction aims to contribute to the ongoing international debate on architectural applications of digital technology and computational design tools and on the impact these have on craftsmanship and architecture fabrication. The case study uses AR-aided construction techniques to augment existing bamboo craftsmanship in order to expand its practically feasible design solution space. Participating laypersons were challenged to work at the interface of technology and material culture and engage with both latest AR systems and century-old bamboo craft. This paper reflects on how AR tracking can be used to create a constant feedback loop between as-built installations and digitally designed source models and how this allows for the real-time assessment of design fidelity and deviations. The case study illustrates that this is especially advantageous when working with naturally varying materials, like bamboo, whose properties and behaviour cannot straightforwardly be accurately simulated digitally. The paper concludes by discussing how augmented feedback loops within the fabrication cycle can facilitate real-time refinement of digital simulation tools with the potential to save time, cost, and material. The augmentation of onsite available skills facilitates the democratisation of non-standard architecture design production.

summary	Bacterial cellulose is a bio self-assembled organic material with unique features such as great tensile strength, biodegradability, and renewable potential that has made it worthwhile for different fields of industrial development research. Since the past decade, in the field of architecture also, enormous efforts were done to reach the desired guided shape of bacterial cellulose with optimized structural features. However, all these efforts are in their infancy. To reach the adaptive architectural bio-component, we need something beyond static prototyping. Therefore, we investigate the specific type "Bacterium Glucoacetobacter xylinus(BC)" cellulose growth procedure by syncing the culture medium (cellulose growth environment) to a virtual stimulating environment to introduce the computational architectural design process based on dynamic biological structures. This research presents the smart design process via the syncing of CAD environment and growth environment to create a framework that provides data analysis that the implementation of its outcomes can revolutionize the bio-digital fabrication process.

title	Digital Fabrication of Growth - Combining digital manufacturing of clay with natural growth of mycelium
source	A. Globa, J. van Ameijde, A. Fingrut, N. Kim, T.T.S. Lo (eds.), PROJECTIONS - Proceedings of the 26th CAADRIA Conference - Volume 1, The Chinese University of Hong Kong and Online, Hong Kong, 29 March - 1 April 2021, pp. 753-762
doi	https://doi.org/10.52842/conf.caadria.2021.1.753
summary	In this paper we will demonstrate that a digital workflow and a living material such as mycelium, make the creation of smart structural designs possible. Ceramics industries are not as technically advanced in terms of digital fabrication, as the concrete or steel industries are. At the same time, bio-based materials that use growth as a manufacturing method, are often lacking in basic research. Our interdisciplinary research combines digital manufacturing - allowing a controlled material distribution, with the use of mycelial growth - enabling fibre connections on a microscopic scale. We developed a structure that uses material informed toolpaths for paste-based extrusion, which are built on the foundation of experiments that compare material properties and observations of growth. In this manner the tensile strength of 3D printed unfired clay elements was increased by using mycelium as an intelligently oriented fibre reinforcement. Assembling clay-mycelium composites in a living state allows force-transmitting connections within the structure. The composite named 'MyCera' has exhibited structural properties that open up the possibility of its implementation in the building industry. In this context it allows the design and efficient manufacturing of lightweight ceramic constructions customized to this composite, which would not have been possible using conventional ceramics fabrication methods.

title	Landscape Visualization by Integrating Augmented Reality and Drones with Occlusion Handling to Link Real and Virtual Worlds - Towards city digital twin realization
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 2, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 521-528
doi	https://doi.org/10.52842/conf.ecaade.2021.2.521
summary	In the field of urban architecture and design, augmented reality (AR)-based landscape visualization is useful for building consensus among stakeholders at the design stage. An integrated AR and drone method can visualize future and past landscapes from an aerial perspective but has to address the problem of occlusion, where a 3D virtual model is displayed in front of the real-world objects. In this study, we propose an AR and drone integrated landscape visualization method to handle occlusion by linking the drone's location information in the real world and the camera in the virtual world. The method uses a 3D model of an existing building, which is part of the city model, to represent the 3D model of the design target as if the target were behind the existing building in the real world. Users can use the perspective of the drone, which flies along a set route, to examine the future landscape with high accuracy, as visualized using AR with occlusion handling.

summary	The integration of VR in the creative process has caused a profound shift in the use of modeling tools and abstraction. How do instantaneous experiential feedback, body awareness, the triggering of spatial sensations, and traveling in real-time from an object-scale to a habitable-scale affect modeling in VR? This research explores the tensions and exchanges between the physical and the digital relative to spatial perception when designing in VR. The work produced by participants involved in a digital design workshop developed around these topics will be presented. In response to a written provocation, participants modeled three-dimensional dreamscapes in VR using Oculus Medium. Participants explored the connection between the body and its movements to measure, model, and control phenomena when animating virtual scenes. This research contributes to the teaching and implementation of modeling in a virtual environment by exploring the inherent possibilities of VR in relation to the conceptualization of spaces.

summary	This study introduces a Grasshopper tool prototype that empowers designers, researchers, and managers to evaluate a design's possible impact on users, compare design alternatives and alter them to better support teamwork as a desired qualitative outcome. This prototype, called TALCAT, is part of an approach called Functional Scenario Analysis (FSA) developed in SimTigrate design lab where stakeholders articulate their needs in brief plain-language statements, then the design research team turns these into criteria for design and specific metrics for measuring designs. Here we present the implementation of TALCAT in a number of Mayo primary-care clinic layouts to analyze, compare, and dynamically visualize teamwork affordance of layouts to support informed design decisions. TALCAT allows very rapid assessment of multiple metrics and allows what-if-testing of new designs as well as constructing new metrics. Moreover, it can address the validity issue in the field by providing consistency in data collection across multiple projects.

summary	This research presents a vision-based Tangible User Interface that was designed to facilitate the investigation of urban spaces. The analogue-digital process made use of inexpensive paper material and commonly accessible technology like a modern camera-enabled phone. Citizens will use a paper-cutting approach to shape the urban space within an urban block and use the phone as the processing agent communicating with a server in the cloud. A three-dimensional visualisation of the urban block may then be viewed on the phone or the computer. A prototype implementation has been developed that allows simple urban massing to be generated. Preliminary tests with groups of users showed promising results. Instead of a conventional design workshop engagement, participants were able to set up the tool in their own time and space and work collaboratively in small groups to developed diverse types of urban layouts.

summary	This article addresses the development and experimentation of a remote application method to help users in social distancing to assess the quality of their creative environments. Therefore, theoretical and practical procedures were adopted to understand the metrics that enhance the creative performance and well-being of environments, and their implementation for spatial analysis through digital instruments and processes. As a result, a set of semi-autonomous and self-applicable tools was developed for collection, processing, visualization and interaction of information regarding the user experiences and environment, making it possible to easily identify problems and potentialities for the elaboration of interventions suited to each situation.

title	Point Cloud Segmentation for Building Reuse - Construction of digital twins in early phase building reuse projects
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. 327–336
doi	https://doi.org/10.52842/conf.ecaade.2023.2.327
summary	Point cloud processing has come a long way in the past years. Advances in computer vision (CV) and machine learning (ML) have enabled its automated recognition and processing. However, few of those developments have made it through to the Architecture, Engineering and Construction (AEC) industry. Here, optimizing those workflows can reduce time spent on early-phase projects, which otherwise could be spent on developing innovative design solutions. Simplifying the processing of building point cloud scans makes it more accessible and therefore, usable for design, planning and decision-making. Furthermore, automated processing can also ensure that point clouds are processed consistently and accurately, reducing the potential for human error. This work is part of a larger effort to optimize early-phase design processes to promote the reuse of vacant buildings. It focuses on technical solutions to automate the reconstruction of point clouds into a digital twin as a simplified solid 3D element model. In this paper, various ML approaches, among others KPConv Thomas et al. (2019), ShapeConv Cao et al. (2021) and Mask-RCNN He et al. (2017), are compared in their ability to apply semantic as well as instance segmentation to point clouds. Further it relies on the S3DIS Armeni et al. (2017), NYU v2 Silberman et al. (2012) and Matterport Ramakrishnan et al. (2021) data sets for training. Here, the authors aim to establish a workflow that reduces the effort for users to process their point clouds and obtain object-based models. The findings of this research show that although pure point cloud-based ML models enable a greater degree of flexibility, they incur a high computational cost. We found, that using RGB-D images for classifications and segmentation simplifies the complexity of the ML model but leads to additional requirements for the data set. These can be mitigated in the initial process of capturing the building or by extracting the depth data from the point cloud.

summary	The developments in recent technologies through Industry 4.0 lead to the integration of digital design and manufacturing processes. Albeit manufacturing continues to increase its importance as design input, it is generally considered at the last stages of the design process. This misconception results in a gap between digital design and fabrication, leading to differences between the initial design and the fabricated outcome in the context of architectural tectonics. Here, we present an artificial intelligence (AI)-based approach that aims to provide a basis to bridge the gap between computation and fabrication. We considered a case study of a 3D model in two stages. In the first stage, an intuitive and top-down design process is adopted, and in the second stage, an AI-based exploration is conducted with three cases derived from the same 3D model. The outcomes of the two stages provided a dataset including different design parameters to be used in a decision tree classifier algorithm which selects the manufacturing method for a given 3D model. Our results show that generative design simulations based on manufacturing constraints can provide a significant variety of manufacturable design alternatives, and minimizes the difference between design alternatives. Using our proposed approach, the time spent in form-finding and fabrication can be reduced significantly. Additionally, the implementation of decision tree classifier learning algorithm shows that AI can serve designers to make accurate predictions for manufacturing method.
