summary	This presentation argues that the concepts of “tools” and “material”, in relation to it use in contemporary architectural design education, can be understood as “instruments” within design processes. The difference between them relies on, its design knowledge abstraction levels, and its mechanisms to capture, manipulate and produce design knowledge. In addition, an initial exploration of Distributed Cognition concept, in order to redefine the use of instruments in design process as Cognitive Instruments, is presented. Furthermore, a more comprehensive framework for design knowledge is presented, including a specific examination of design instruments an its role indesign processes. In the conclusions possible effects derived from the use of “instruments” in design processes are explored.

summary	This research explores new ways to integrate manufacturing knowledge in to design phases. Through the use of design for manufacturing (DfM) concept, and looking at relations between its potential application in component design and its implementation using digital manufacturing technologies, the author implemented a DfM model that varies from previous models by incorporated learning in the process. This process was based on; a knowledge systematization process; and the incremental development and refinement of design heuristics and metrics. Subsequently the attempt on this research is twofold. One is to realize a process to capture and organize manufacturing knowledge, and second to organize that knowledge and make it available as a DfM model for component design using specific CNC technology.

title	Variaciones intensivas: diseño paramétrico de edificios en altura basado en análisis topológico [Intensive variations: parametric design of tall buildings based on topological analysis]
source	SIGraDi 2010_Proceedings of the 14th Congress of the Iberoamerican Society of Digital Graphics, pp. Bogotá, Colombia, November 17-19, 2010, pp. 129-132
summary	Several building works have demonstrated the possibilities of architectural design based on structural performance. This work discusses some examples and digital design strategies that approach this issue, as well as an exercise for a tower generated through topological optimization. That experience presents alternatives for a traditional office tower in Santiago, Chile, the Torre Santa Maria, based on generative design strategies for the incorporation of structural and environmental requirements to define parametric models. The experience and the capabilities studied reveal an intensive variation of architectural shape. This approach challenges conventional building regularity and suggests new ways of designing based on material performance.

title	Does the Debate on Stress Effect Lead Evacuation Simulation Models to Different Performances?
doi	https://doi.org/10.52842/conf.caadria.2013.179
source	Open Systems: Proceedings of the 18th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2013) / Singapore 15-18 May 2013, pp. 179-187
summary	There exists a long time debate over the rational state of the evacuees in the evacuation simulation. Sime et al. insisted that the evacuees behave rationally in most cases. Following this argument Arthur and Passini concluded that if a setting works well under normal conditions, it will have a better chance of working well in emergency conditions. Such an argument for rational decision-making makes statistical models, such as Utility Maximizing Model (UMM), acting as proper framework for choice modelling in evacuation. However, on the other side, some people pointed out that there exists panic in the evacuation and bounded rationality theory, represented by pruned Decision Tree Model (DTM), should be adapted in choice modelling instead. Such a debate over stress effect causes hesitations and uncertainties when researchers try to select a proper model framework for their practical simulation. This study compared the performances (prediction accuracies) of the UMM and DTM with the same set of choice data collected in a virtual evacuation experiment. With a similar level of performance on both sides, it is suggested that the on-going debate does NOT bring any difference to the choice modelling in practical evacuation simulation. It is time to improve the performance rather than to continue the debate.

title	Towards a Computational Spatial Knowledge Acquisition Model in Architectural Space
source	Global Design and Local Materialization[Proceedings of the 15th International Conference on Computer Aided Architectural Design Futures / ISBN 978-3-642-38973-3] Shanghai, China, July 3-5, 2013, pp. 256-266.
summary	Existing research which is related to spatial knowledge acquisition often shows a limited scope because of the complexity in the cognition process. Research in spatial representation such as space syntax presumes that vision drives movement. This assumption is only true under certain conditions and makes these models valid only in specific scenarios. Research in human spatial cognition field suggests that the spatial information perceived by the individual is not equal to the visual appearance of the space, a straightforward way to represent this cognition process quantitatively is lacking. Research in wayfinding usually assumes a certain degree of familiarity of the environment for the individual, which ignores the fact that the individual sequentially perceives information during wayfinding and the familiarity of the environment changes during the wayfinding process. In this paper, a conceptual spatial knowledge acquisition model for architectural space is presented based on the continuous spatial cognition framework. Three types of local architectural cues are concluded to relate common architectural elements to the continuous spatial cognition framework. With all relations in the proposed conceptual model quantitatively described, a computational model can be developed to avoid the aforementioned limitations in spatial representation models, human spatial cognition models and wayfinding models. In this way, our computational model can assist architects evaluate whether their designed space can be well perceived and understood by the users. It can help enhance the way-finding efficiency and boost the operational efficiency of many public buildings.

title	Biocentric Design: Mapping Optimal Environmental Variables for Moss Propagation on Urban Bioreceptive Surfaces
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. 1251–1262
summary	The biocolonisation of urban building surfaces by mosses is a ubiquitous and naturally occurring phenomenon that encapsulates immense ecological value for both current and future challenges of life in cities. The miniature ecosystems facilitated by mosses capture atmospheric pollutants and maintain local biodiversity by providing shelter and nutrients for a highly diverse set of organisms across all kingdoms of life. Early establishment and growth of bryophyte communities appear to be influenced by a dynamic mix of biotic and abiotic factors, while environmental cues modulate physiological responses and biochemical exchanges. A prototype monitoring device was designed to measure carbon dioxide uptake under variable light, humidity, and temperature conditions during a 3-week experiment. By providing a non-destructive tool for understanding and visualising the impact of environmental variables on photosynthetic behaviour, the device contributes to a biocentric design practice, where an organism’s ecological needs begin to drive the development of bioreceptive micro-environments.

summary	One of the most important natural resources for the urban sustainability is water. For this reason, the incorporation of appropriate strategies to manage water resources from buildings and urban planning is necessary. In this work a series of parametric criteria are defined, with which by using design software it proposed generating optimal forms in certain scenarios for high hydric performance in urban residential complexes. The examples developed demonstrates strong influences of dwelling density by the construction block and permeable outdoor surfaces, as well as local infrastructure for water recovering.

source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 804-807
summary	This research focuses on an approach to describe principles in non-destructive floor space relocation within the domain of revitalization. With the aid of mathematical rules, which are executed by the use of a computer, solutions to floor space relocation problems are generated. Provided that “design” is in principle a combinatorial problem, i.e., a constraint-based search for an overall optimal solution, an exemplary method is described to solve such problems.

summary	The existent and idle stock of buildings is extensive. However, significant information about these buildings is hardly available. The real estate owners are usually not known by prospective customers and they can be elicited only with substantial effort. But even if data about a building is available, it is difficult to valuate it precisely, because there are no standard classification techniques available, which would also consider the subjective subsequent requirements of the interested parties. The question whether a building is suitable for a certain subsequent use is therefore hard to answer. It involves an extensive expenditure of time and manpower. No reliable statement about a prospective reuse of a building can be made on site by prospective clients, i.e. buyers or renters. Therefore, we examined the technology needed by the customer to accomplish in-situ ad-hoc analyses of existing buildings. These technologies are namely remote sensing devices using georeferenced data, Location-Based Services and web-based optimization techniques. The aim is to give prospective clients the possibility to visit a building and run an in-situ usability simulation. To accomplish this, building information will be transferred between the building and the client through the use of common communication devices. These devices automatically connect to server-based applications, which compare the requirements of the prospective customer with the existing building and run remote simulations on concrete further utilization. By the use of georeferenced data alternative locations of unused buildings can be integrated into the simulation as well.

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.

title	DIFFERENCE BETWEEN EXPERT AND NOVICE DESIGNERS: AN EXPERIMENTAL STUD
source	Human Behaviour in Design, edited by U Lindemann, Springer, Berlin, pp 42-51.
summary	This chapter investigates the differences in performance between an expert and a novice in terms of their respective strategic knowledge. We examined conceptual design protocols of an expert and a novice, and found that the expert’s cognitive activity and productivity in the design process were almost three times as high as the novice's. The possible reason for this is the difference in their strategic knowledge. The expert’s cognitive processing is structured such that it stays within the limits of human short term memory. This provides empirical evidence for a different strategic knowledge that may be developed with experience. The expert's strategic knowledge allows him to use a smaller number of processes and to form different groupings of processes.

title	A cooperative model using semantic works dedicated to architectural design
doi	https://doi.org/10.52842/conf.caadria.2005.094

summary	Architectural cooperative design as well as information modeling have been active research areas for several decades. The use of systems adapted to the cooperative design assistance for the building domain is complex. This results from the complexity of the cooperative work (difficulties in tracking actor’s work, lack of most of the required information, coordination problems, implicit nature of most of the construction activities, etc.) The main objective of our research in these domains is to develop a tool that helps the management of a building project and aids cooperative design. So, in the first part of this article, we propose to view the exchanging data mode and cooperation tools in the building domain. The second part of this article illustrates the existing cooperative design models. Then we justify the interest shown in a new model of cooperative design where the relational organization of the project and the semantic meaning of works are taken into account. Finally, we use this new model for defining a design-aided tool, to deduce advantages and limits of the “Virtual Cooperative Project”.

summary	The use of technology instigates student interest. Thus, the possibilities offered by the technologies should be presented to students during their professional training. This paper aims to propose to teachers a change in the approach of 'geometry' contents through the use of BIM, Augmented Reality, Virtual Reality, Rapid Prototyping and Digital Fabrication. The methodology chosen was Systematic Review of Literature and literature review without meta-analysis. It presents an overview of the applicability of such technologies in teaching, as well as possibilities little explored. The results indicate that 'geometry' teaching can benefit from the great potential offered by Information and Communication Technologies.

title	Abstract but Tangible, Complex but Manageable
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	In the VR-DIS research program, an innovative design-information modelling technique has been proposed that is based on features. In this modelling technique, the designer is invited not only to model the form and spatial aspects of his or her design, but also to model the structure of the data behind the design. The designer is offered a way to control how abstract design data is structured and stored. In this way, the designer is given the power to model concepts like conformity, contrast, and scale on the formal data level, and this for both graphical and non-graphical design characteristics. Further, the designer is invited to input formal descriptions of own design concepts, and use these personal concepts during the design process. With this new information modelling technique, we expect that the designers will be better capable to handle the complexity of linking diverse kinds of information involved in a design process. This new way of computer aided design offers a unique design freedom: any design concept becomes addressable. On the other hand, this technique also puts the responsibility for the content of the CAD database entirely in the hands of the designer. In order to be able to enjoy the design freedom fully and at the same time handle the responsibility over the design database, a computer tool is needed that shows the precise content of the database, and that is easy and quick to interact with. Only with such a tool, the designer will be capable of keeping the complex data model in pace with his or her design reasoning. To realise this requirement, a “feature browser” has been developed with a 3D graphical user interface. It shows the data objects as 3D blocks, mutually linked by rubber-band arrows that closely reflect the database structure. The whole forms an interactive 3D graph. The intuitiveness and user friendliness of the interface was improved by adding features like the visualisation of the browsing history, the visualisation of link-semantics, and animated visual feedback effects. The hardware part of the interface is worked out as a Fish Tank VR set-up. This hardware configuration improves the experienced realism of the displayed 3D objects up to a feeling of physical presence. The interface as a whole therefore provides a highly attractive display of the abstract design data; abstract but tangible. It is a tool in which complex data structures can be explored and controlled: complex but manageable.

summary	The purpose of this work is to design a spatially-aware tangible interface for interactive 3D visualization. We explore an integrated platform whereby digital representations are integrated with physical artifacts. Our work provides a means to display separated perspective views of a design on multiple-projection physical planes. Users can directly interact with the physical planes to view digital information. By coupling physical artifacts with digital representations, the view of 3D information is mapped to physical space. Our work reduces the cognitive load on novice designers, and enhances the user's capability of understanding the relationships between multiple design representations.

summary	Physarum Polycephalum is a widespread eukaryotic microbe capable of producing effective networks between food particles to solve spatial planning problems. This paper investigates a previous algorithm for simulating Physarum Polycephalum. An open-source tool named Physarealm is developed for simulation in Rhino's graphical algorithm editor, Grasshopper. The tool adopts a previous stigmergic multi-agent algorithm for simulation and expands its boundary into three dimensions. In addition, this tool adds some custom rules, thus giving the designer more creative control over the produced results. Two research projects have applied this tool in the design process. The first project mainly takes advantage of the tool's path-planning ability, while the second one utilizes its aesthetic values, demonstrating the potential of the tool for further applications.

summary	Recent developments in digital fabrication have made increasingly intelligent use of machine visioning and 3D scanning. These technologies enable ever-higher resolution digital models of physical material, and present opportunities for physical material to gain agency in the design process. Digital design workflows using such technologies require ever-greater computing power as the resolution of digitized models increases, and high-fidelity 3D scanning systems become cost-prohibitive, creating obstacles to widespread use. Twinned assemblage uses consumer-grade photogrammetry software, lowering the cost of equipment required, and presents a series of distillation methods that strategically reduce the fidelity of data digitally describing a physical object. Distillation methods discussed include reducing a mesh to a low-poly geometry, identifying the location and orientation of an object's largest faces, and creating 2D sections, among others. These methods can be designed intentionally to extract or highlight certain qualities in digital models, that in turn inform aggregation strategies generated through computational simulation. This paper presents several examples of such aggregations in a variety of materials, conveying benefits and challenges of the process. Such methods present opportunities for granting agency to physical materials in the design process, and for the democratized use of digitizing technologies.

title	Aspen Leaves as a Biological Role Model for a Triboelectric Wind Energy Harvesting Building Facade System
doi	https://doi.org/10.52842/conf.ecaade.2024.2.597
source	Kontovourkis, O, Phocas, MC and Wurzer, G (eds.), Data-Driven Intelligence - Proceedings of the 42nd Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2024), Nicosia, 11-13 September 2024, Volume 2, pp. 597–606
summary	Biological role models are a growing focus of research in wind energy harvesting technology. Rotational elements (blades)are well known but there have been limited studies looking at galloping instability (fluttering effect) for electricity harvesting via the triboelectric effect. Some previous studies have demonstrated the potential of galloping blades, or triboelectricity, by coupling with piezoelectric systems. However, there are not any known studies that have studied the potential architectural implementation of these systems in building applications. Here, a bio-inspired mechanism is presented that combines bio-mechanical properties observed in the distinctive fluttering of the Aspen (Populus Tremuloides) leaves, to test the potential for adaptive building facade systems that can produce electricity in response to the low-speed winds found in urban environments. The research outlines the principles behind the distinctive fluttering pattern of the Aspen leaf, also known as torsional galloping, and shows a 3DP strategy to create functional models that can replicate its motion. The bio-inspired actuator was subsequently coupled with a proof-of-concept triboelectric set-up to evaluate its potential for energy harvesting. Lastly, a speculative design for an urban building application was proposed to assess the technical and aesthetic implications of these types of systems. We hope that this initial investigation can contribute towards the future development of smart, adaptable, and sustainable integrative façade systems that will use local environmental conditions to harvest energy and therefore reduce reliance on non-renewable energy.

With computer graphics, 3d digital models can be used during the design process to verify these functions. Thus, the goal of this paper is to compare and analyze the different digital 3D models obtained (built virtually or through 3D scanning) of a cobogó existing in the Brazilian market, so that visual and lighting differences can be observed, and how these differences can impact the design process.
