title	PRONTO KIDS CHAPECo: digital prototyping and fabrication workshops focused on the perception of the built environment for children in the public school system
source	SIGraDi 2020 [Proceedings of the 24th Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Online Conference 18 - 20 November 2020, pp. 775-782
summary	The inclusion of digital fabrication and prototyping in the school environment contributes significantly to learning, stimulating the cognitive process of students. The objective is to introduce concepts of these technologies to students from municipal public schools, relating to the built environment. The action research procedure is developed through practical workshops in a university's laboratory. The workshops promoted clarification about digital technologies for children, encouraging them to reflect on elements that promote improvement in the built environment. The approach with technologies since the beginning of citizen education, points to societies aware of the transformations in the environment in which they live.

title	Holonavi - A study on User Interface for Assembly Guidance System with Mixed Reality in a Timber Craft of Architecture
source	D. Holzer, W. Nakapan, A. Globa, I. Koh (eds.), RE: Anthropocene, Design in the Age of Humans - Proceedings of the 25th CAADRIA Conference - Volume 1, Chulalongkorn University, Bangkok, Thailand, 5-6 August 2020, pp. 691-700

summary	This paper introduces ideas to use Mixed Reality (MR) technologies in craftsman's work of architecture.One of the backgrounds of this study is emerging technology of Mixed Reality becoming much easier to use recently with new devices such as Microsoft Hololens. Among many possible applications of this technique in architectural work, we particularly choose Japanese traditional timber joinery 'Kumiki' as a model case of complicated architectural work.We found that people need a certain sense of 3D recognition and knowledge about right order of assemble. That is what we can suggest for users with our MR guidance system named 'Holonavi' which can show appropriate information in 3D vision in real time. The aim of our research is to find useful knowledge about effective ways and sufficient information to guide users. As a conclusion, we found that guidance with MR technology gives users to have a recognition more effectively for take of right action when they are moving their viewpoint around the object and when they located in the range of reachable distance to the objects. It is the first achievement for use of 'Holonavi' to let people feel more fun to craft something by their hands aided by computer.

title	Shape Grammars as a Method to Introduce Computational Thinking in Design - The case of tiles
source	Werner, L and Koering, D (eds.), Anthropologic: Architecture and Fabrication in the cognitive age - Proceedings of the 38th eCAADe Conference - Volume 1, TU Berlin, Berlin, Germany, 16-18 September 2020, pp. 693-702
doi	https://doi.org/10.52842/conf.ecaade.2020.1.693
summary	For architects and other artists, shape grammars, that are part of the computational thinking concept, have been an effective initial tool of transition between the realm of design and the classic computer. The dissemination of computer science and its mindset is only possible when it is supported by adequate pedagogical processes. The presented paper demonstrates an adequate transposition of art solutions (part of tile panels by Athos Bulcao and Maria Keil) into a computational structure where innovative notations are defined in some aspects. To that end, it allows their implementation in the computer through a suitable programming language and uses those same notations to generate other solutions within the same universe of interest and research. Furthermore, an intellectual process is exposed allowing to structure the information, particularly regarding to form, to different frameworks, placing itself as an opportune methodological structure that can guide other similar experiences.

title	Designing with Uncertainty - Objectile vibrancy in the TOROO bamboo pavilion
source	D. Holzer, W. Nakapan, A. Globa, I. Koh (eds.), RE: Anthropocene, Design in the Age of Humans - Proceedings of the 25th CAADRIA Conference - Volume 2, Chulalongkorn University, Bangkok, Thailand, 5-6 August 2020, pp. 507-516
doi	https://doi.org/10.52842/conf.caadria.2020.2.507
summary	This paper challenges digital preoccupations with precision and control and questions the status of tolerance, allowance and error in post-digital, human-centred architectural production. It uses the participatory action research design-and-build project TOROO, a light-weight bending-active bamboo shell structure, built in Hsinchu, Taiwan, in June 2019, as a demonstrator project to discuss how protean digital design diagrams, named 'vibrant objectiles,' are capable of productively absorbing serendipity throughout project crystallisation processes, increasing designer agency in challenging construction contexts with high degrees of unpredictability. The demonstrator project is then used to discuss future research directions that were exposed by the project. Finally, the applicability of working with 'vibrant objectiles' is discussed beyond its local project use. Common characteristics and requirements are extracted, highlighting project setup preconditions for which the scope covered by the architect needs to be both broadened and relaxed to allow for feedback from design implementation phases.

title	Integrating Design Studio Teaching with Computation and Robotics in Hong Kong
source	D. Holzer, W. Nakapan, A. Globa, I. Koh (eds.), RE: Anthropocene, Design in the Age of Humans - Proceedings of the 25th CAADRIA Conference - Volume 2, Chulalongkorn University, Bangkok, Thailand, 5-6 August 2020, pp. 343-350
doi	https://doi.org/10.52842/conf.caadria.2020.2.343
summary	There is a persistent need among Hong Kong Architecture students to develop greater aptitude for critical and design thinking. The mechanics of criticality entail observation, reflection and the development of a knowledgeable response. This important process aligns with a tool-based iterative design research approach, where a cycle of action, observation, reflection, and reaction can take place. In order to complement fundamentals in architectural design, a focus on tools and tool-making approaches toward the development of a critical architectural proposal needs to be incorporated into core curriculum. Through the integration of robotics, automation and computational design approaches into the design studio environment, tool making for producing architectural media (drawings and models) can most effectively be explored. With an emphasis on design and programming tools for component fabrication and assembly, students can develop their own criterion for evaluation as a knowledge-based response to their investigations and proposed architectural systems.

title	Design Process for a Soft Flexible Palm - Improving grasp strength in an anthropomorphic end effector for collaborative robots in construction
source	Werner, L and Koering, D (eds.), Anthropologic: Architecture and Fabrication in the cognitive age - Proceedings of the 38th eCAADe Conference - Volume 2, TU Berlin, Berlin, Germany, 16-18 September 2020, pp. 423-432
doi	https://doi.org/10.52842/conf.ecaade.2020.2.423
summary	This paper describes an iterative design process to create an anthropomorphic end-effector for a collaborative robot in construction. The focus is on improving the palm or juncture of the handlike end effector. Anthropomorphic end effectors typically have stiff, rigid palms that only provide support to the fingers rather than being an active part of the end effector. This research contributes to new knowledge through a detailed investigation of the role the palm has in improving the grip strength and control. This control and strength is essential for operating tools commonly used on construction sites. Consequently, the paper asks the question and investigates if a flexible palm could provide added support and grip for end effectors needed for complex processes.Via an action-based research method, the paper uses soft robotic techniques to experiment with a range of pneumatic iterative solutions to create a functioning palm, inspired by the human hand. The resulting end effector will aim to mimic the behaviours of the human hand.This investigation, its proposed hypothesis, methodology, implications, significance and evaluation are presented in the paper.

summary	Waning of vigorous discourses about the idea of space as essence in architectural design concurred with the emergence of digital architecture. The notion of space was replaced with the underlying notion of form facilitating optimization of performances and form-generation in digital design ever since. Within the context of digital architecture, the current research investigates a formal method to reintroduce spatial aspects, based on dynamics of architectural space in relation to form, into digital design processes. Accordingly, a computational framework is devised employing the idea of space as dynamic field conditions, in order to capture dynamic interrelation of architectural space with architectural form. That is, spatial dynamics are regarded as data embedded in architectural space, that can imply operational aspects of spatial experiences and / or stimulate corporeal engagements with experiential space, as concepts as action potentials and affordances do (Rasmussen 1964). As a result, the research aims to contribute to the body of knowledge that endeavour to systematize architectural sensibilities that are implicit in design processes by externalization utilizing computation.

title	Digital Stupefaction - Seduction and Complacency of Digital Techniques
source	D. Holzer, W. Nakapan, A. Globa, I. Koh (eds.), RE: Anthropocene, Design in the Age of Humans - Proceedings of the 25th CAADRIA Conference - Volume 2, Chulalongkorn University, Bangkok, Thailand, 5-6 August 2020, pp. 351-360
doi	https://doi.org/10.52842/conf.caadria.2020.2.351
summary	Digital design techniques have saturated architectural discourse in the past forty-plus years from modelling to simulation and fabrication. Digital or Computational Design now forms part of the standard architectural curriculum, promising efficiency in modelling, design, advancing site analysis and ease of fabrication. Alongside these promises, we as educators begin to witness a new level of complacency governed by the use of the digital tools; we call this Digital Stupefaction. With the increasing 'smartness' of digital tools, what is the risk of shifting away from the focus of what students should/could know, and what information they embody? Is it still relevant to be able to draw on intrinsic background knowledge, or tacit knowledge in action, when everything can be analysed and verified on the fly (or even pre-selected via AI)? How can educators respond to these challenges by adjusting the way they deliver subjects associated with digital design?

summary	In parametric design-oriented elective courses given in the architecture departments, most of the parametric designs generally remain at the modeling stage and cannot pass to the design application stage. In this study, this situation was determined as a research problem. Therefore, an experimental method within the scope of the parametric design course was considered. The applied method was discussed and the result product was evaluated. The applied method not only overcame the research problem, but also helped students to develop creativity and collaborative competency.

title	Methodology for the abstraction and morphological experimentation of nature’s patterns: an application case of morphology research subject in Industrial Design program
source	SIGraDi 2020 [Proceedings of the 24th Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Online Conference 18 - 20 November 2020, pp. 217-222
summary	Forms in nature have been emerging in response to different requirements, in a complex and dynamic ecosystem. Architects and designers have usually used references from nature for their projects; in industrial design education, the use of nature’s referents allows to expand the morphological possibilities for product design and systems. In this paper, a methodological proposal for the abstraction and morphological transformation of nature’s patterns is presented, highlighting the advantages of parametric design and additive manufacturing technologies for morphological experimentation, in the context of the first application case of morphology research subject in the Industrial Design program at Universidad Pontificia Bolivariana.

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	Modeling of steel and precast concrete components based on BIM systems and their application for the teaching of Architectural Design
source	SIGraDi 2020 [Proceedings of the 24th Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Online Conference 18 - 20 November 2020, pp. 652-659
summary	This paper addresses the development of parametric components based on BIM (Building Information Modeling) tools and their application for the teaching of architecture and urban designs, in a discipline focused on housing typology. As a didactic and research method, the use of industrialized building technologies in steel and precast concrete for production efficiency and low maintenance is associated with the idea of the studio as a laboratory for verification and experimentation. The system was improved for two years, and provided students with greater constructive control, basic feedback on the budget, and mastery of representation, while they investigated alternative design concepts and new components.

title	Visualise Energy Saving Potentials in Settlement Development: By linking transport and energy simulation models for municipal planning

doi	https://doi.org/10.52842/conf.ecaade.2024.2.079
summary	To achieve Sustainable Development Goals, in addition to the switch to sustainable energy sources and energy-efficient buildings, transport offers a major lever for reducing energy consumption and greenhouse gases. The increasing demand for emission-free mobility (e.g. through electromobility) but also heat pumps has a direct impact on the electricity consumption of buildings and settlements. It is still difficult to simulate the effects and interactions of different measures as sector coupling concepts require comprehensible tools for ex ante evaluation of planning measures at the community level and the linking of domain-specific models (energy, transport). Using the municipality of Bruck an der Leitha (Austria) as an example, a digital twin based on an open data model (Bednar et al., 2020) is created for the development of methods, which can be used to simulate measures to improve the settlement structure within the municipality. Forecast models for mobility (Schmaus, 2019; Ritz, 2019) and the building stock are developed or applied and linked via the open data model to be able to run through development scenarios and variants. The forecasting and visualisation options created in the project form the basis for the ex-ante evaluation of measures and policies on the way to a Positive-Energy-District. By identifying and collecting missing data, data gaps are filled for the simulation of precise models in the specific study area. A digital, interactive 3D model is created to examine the forecast results and the different scenarios.

summary	In architectural design, evolutionary multiobjective optimization algorithms (EMOA) have found use in numerous practical applications in which qualitative and quantitative aspects can be transformed into fitness functions to be optimized. This paper shows that they can be used in an architectural plan design process that starts from a more traditional approach. The benchmark case uses a novel construction system, called Ac.Ca. Building, with a vast architectural and technological database, arleady validated, to generate architectural plan for a residential towerbuilding with a parametric approach and EMOA. The proposed framework differs from past research because uses spatial units with high level of architectural and tecnological definition.

summary	Gamification is the application of game-oriented design approaches or game-inspired mechanics to otherwise non-game contexts. Mobile guiding system is the design process of information interactions. It is the integration of information design, interaction design, and sensorial design. The e-learning system of mobile guide is able to be loaded gamification concepts and let mobile learning interestingly, diversely, and validly. The problem of the research was if we combined the concept of gamification design into museum guide services with augmented reality for non-commercial purposes, it also provided the same benefits to the promotion of museum learning and knowledge, integrating mobile devices as navigation media. It would improve more users to participate in a museum and use the guide system actively, and then arise their interest and achievement. The result was to establish a preliminary model for developing a museum mobile guide system of gamification design and augmented reality.

summary	Style transfer is a design technique that is based on Artificial Intelligence and Machine Learning, which is an innovative way to generate new images with the intervention of style images. The output image will carry the characteristic of style image and maintain the content of the input image. However, the design technique is employed in generating 2D images, which has a limited range in practical use. Thus, the goal of the project is to utilize style transfer as a toolset for architectural design and find out the possibility for a 3D modeling design. To implement style transfer into the research, floor plans of different heights are selected from a given design boundary and set as the content images, while a framework of a truss structure is set as the style image. Transferred images are obtained after processing the style transfer neural network, then the geometric images are translated into floor plans for new structure design. After the selection of the tilt angle and the degree of density, vertical components that connecting two adjacent layers are generated to be the pillars of the structure. At this stage, 2D style transferred images are successfully transformed into 3D geometries, which can be applied to the architectural design processes. Generally speaking, style transfer is an intelligent design tool that provides architects with a variety of choices of idea-generating. It has the potential to inspire architects at an early stage of design with not only 2D but also 3D format.

summary	As we continue to discover the potential of social media data as an insightful source for academic research, the majority of previous work tends to focus on the density of socio-spatial relations as the foundation for understanding urban phenomena. This paper extended those approaches by introducing the concepts of diversity and inclusiveness through an investigation of the 'differences' within the networks of relations that are inherent to social media data. The author constructs a diversity measure based on the variety of home locations of social media user visitors to each geographical location in the city. This home location, in its turn, is derived from each user's digital spatio-temporal footprint. This proposed method demonstrates that through the visualization of this diversity measure, 'social hubs' (which are frequently visited by different groups of people) were able to be located that would otherwise be overlooked in conventional data analyses that focus only on density. As such, this research expands the usefulness of social media as a practical tool to help understand urban processes by making the concept of diversity - a key consideration in many planning and design contexts - measurable and mappable.

summary	Virtual reality (VR) and augmented reality (AR) have been proposed to be additional architectural design mediums for at least 25 years (Dagit, 1993). Despite rapid technical and technological development, it has not been adopted into architectural design practices as compared to academia and research. Surveys from the American Institute of Architects (AIA) and Royal Institutes of British Architects (RIBA) demonstrate the state of architectural practices; 72% of architects and 65% of architects respectively are not using any kind of virtual, augmented, or mixed reality in their practices(RIBA and Microsoft, 2018; Hampson, 2020). In this paper, the authors investigate the state of practices, issues, challenges, and opportunities of the utilization of virtual, augmented, and mixed realities in six architectural practices in the Danish context. Three of the practices are large architectural practices, one medium-sized practice specializing in institutional, healthcare and cultural architecture, and one firm designing private family houses, kindergartens, daycares and places for people with disability and, one experimental design studio. All these practices have used VR/AR in their projects to various degrees. In recent years Danish architectural practices have been involved in various VR/AR-based exhibitions, demonstrations, and tool developments to promote the usage of the same in design practice. Through a set of qualitative interviews with personnel from key architectural practices, the authors would like to demonstrate the present state of practices. The investigation explores the usage of VR and AR in Danish architecture practices by identifying challenges and opportunities regarding skill levels, architectural typology, use cases, toolchains, and workflow and shows similarities and differences between traditional and VR-based design processes. The main findings show how VR/AR-based visualization helps architects to perceive spatiality and also ushers creativity through immersion and overlays.

summary	In recent years, there has been a growing interest in adopting circular approaches in the built environment, specifically reusing existing buildings or their components in new projects. To achieve this, drawings, laser scanning, photogrammetry and other techniques are used to capture data on buildings and their materials. Although previous studies have explored scan-to-BIM workflows, automation of 2D drawings to 3D models, and machine learning for identifying building components and materials, a significant gap remains in refining this data into the right level of information required for digital twins, to share information and for digital collaboration in designing for reuse. To address this gap, this paper proposes digital guidelines for reusing precast concrete based on the level of information need (LOIN) standard EN 17412-1:2020 and examines several CAD and BIM modelling strategies. These guidelines can be used to prepare digital templates that become digital twins of existing elements, develop information requirements for use cases, and facilitate data integration and sharing for a circular built environment.
