title	Critical points for change - A vital mechanism for enhancing the conceptual design process
doi	https://doi.org/10.52842/conf.ecaade.2006.098

summary	The Conceptual design is not a linear process; it consists of sub-processes, levels of refinement, which are individual but interact with each other. Each level of refinement corresponds to the types of media and tools used during conceptual design. Architects take advantage of a broad palette of tools and media for design, because each tool has its own strengths and weaknesses and provides an additional value—an added level of vision—to the architect. This closely relates to the notion of Critical Points for Change (CPC) a contribution this study makes towards a better understanding of the uniqueness of the conceptual design process. CPC are crucial moments when the architect suddenly becomes able to “see” something which drives him to go back and either alter his idea and refine it or reject it and pursue a new one. They are crucial parts of the design process because they are a vital mechanism for enhancing design. This characteristic of the nature of the conceptual design process is independent of the tools. Nevertheless, the right tools play an extremely important role. The distinctive capabilities of each tool allow the architect to deal successfully with CPC and overcome the points in the design process where he or she feels “stuck.”

title	Reciprocal Transformations Between Music and Architecture As a Real-Time Supporting Mechanism in Urban Design
doi	https://doi.org/10.52842/conf.ecaade.2015.1.493
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 1, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 493-499
summary	The more complex our cities become the more difficult it is for designers to use traditional tools for understanding and analyzing the inner essence of an eco-system such as the contemporary urban environment. Even many of the recently crafted digital tools fail to address the necessity for a more holistic design approach which captures the virtual and the physical, the immaterial and the material. Handling of massive chunks of information, classification and assessment of diverse data is nowadays more crucial than ever before. We see a significant potential in combining the fields of composition in music and architecture through the use of information technology. Merging the two fields has the intense potential to release new, innovative tools for urban designers. This paper describes an innovative tool developed at the Technical University of Crete, through which an urban designer can work on the music transcription of a specific urban environment applying music compositional rules and filters in order to identify discordant entities, highlight imbalanced parts and make design corrections. Our cities can be tuned.

title	Analog vs. Digital: why bother?
source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 117-128
summary	Architects take advantage of a broad palette of tools and media for design, analog and digital, because each tool has its own strengths and weaknesses and provides an additional value—an added level of vision—to the architect. This closely relates to the notion of Critical Points for Change (CPC) a contribution this study makes towards a better understanding of the uniqueness of the conceptual design process. CPC are crucial moments when the architect suddenly becomes able to “see” something which drives him to go back and either alter his idea and refine it or reject it and pursue a new one. They are crucial parts of the design process because they are a vital mechanism for enhancing design. The right choice and smooth combination of design tools, analog and digital, is critical for the design outcome. Using multiple tools allows the designer to overcome the possible influences and limitations imposed by a single tool. The current and evolving landscape is illustrated by coexistence, complementing and evolution of tools. The answer to the pseudo-dilemma of analog or digital is both.

summary	This article describes the experiences in the teorical – practical course “Computer Asisted Design – Level II” in the Architecture career, offer by the LTAD - FAU – UCV. We gave as models to the students of our course real art works, located and visitable in the universiy campus, offering the construction of detailed digital files of them, that will be publish in Internet. Files that can be use in the inventary and conservation of those art works. Important exercise if we consider that this art works are part of theUNESCO Human Cultural Patrimony (http://www.unesco.org). We want that our University asumes this iniciative as integral part of the inventary, conservation and divulgation of the art works integrated to the buildings in the UCV Campus.

title	Function representation in geometric modeling: concepts, implementation and applications
source	The Visual Computer, 11 (8) 429-446
summary	Geometric modeling using continuous real functions of several variables is discussed. Modeling concepts include sets of objects, operations and relations. An object is a closed point set of n-dimensional Euclidean space with a defining inequality f x x xn ( , ,..., ) 1 2 0 °Ÿ . Transformations of a defining function are described for the set-theoretic operations, blending, offsetting, bijective mapping, projection, Cartesian product and metamorphosis. Inclusion, point membership and intersection relations are described. In the implemented interactive modeling system, we use highlevel geometric language that provides extendibility of the modeling system by input symbolic descriptions of primitives, operations and predicates. This approach supports combinations of representational styles, including constructive geometry, sweeping, soft objects, voxel-based objects, deformable and other animated objects. Application examples of aesthetic design, collisions simulation, NC machining, range data processing, and 3D texture generation are given.

title	Bio-digital aesthetics as value system of post-Anthropocene architecture
source	International Journal of Architectural Computing vol. 18 - no. 2, 120-140
summary	It is timely within the Anthropocene era, more than ever before, to search for a non-anthropocentric mode of reasoning, and consequently designing. The PhotoSynthetica Consortium, established in 2018 and including London-based ecoLogicStudio, the Urban Morphogenesis Lab (Bartlett School of Architecture, University College London) and the Synthetic Landscape Lab (University of Innsbruck, Austria), has therefore been pursuing architecture as a research-based practice, exploring the interdependence of digital and biological intelligence in design by working directly with non-human living organisms. The research focuses on the diagrammatic capacity of these organisms in the process of growing and becoming part of complex bio-digital architectures. A key remit is training architects’ sensibility at recognising patterns of reasoning across disciplines, materialities and technological regimes, thus expanding the practice’s repertoire of aesthetic qualities. Recent developments in evolutionary psychology demonstrate that the human sense of beauty and pleasure is part of a co-evolutionary system of mind and surrounding environment. In these terms, human senses of beauty and pleasure have evolved as selection mechanisms. Cultivating and enhancing them compensate and integrate the functions of logical thinking to gain a systemic view on the planet Earth and the dramatic changes it is currently undergoing. This article seeks to illustrate, through a series of recent research projects, how a renewed appreciation of beauty in architecture has evolved into an operational tool to design and measure its actual ecological intelligence.

summary	Ubiquitous computing enables us to decipher the biosphere’s anthropogenic dimension, what we call the Urbansphere (Pasquero and Poletto 2020). This machinic perspective unveils a new postanthropocentric reality, where the impact of artificial systems on the natural biosphere is indeed global, but their agency is no longer entirely human. This paper explores a protocol to design the Urbansphere, or what we may call the urbanization of the nonhuman, titled DeepGreen. With the development of DeepGreen, we are testing the potential to bring the interdependence of digital and biological intelligence to the core of architectural and urban design research. This is achieved by developing a new biocomputational design workflow that enables the pairing of what is algorithmically drawn with what is biologically grown (Pasquero and Poletto 2016). In other words, and more in detail, the paper will illustrate how generative adversarial network (GAN) algorithms (Radford, Metz, and Soumith 2015) can be trained to “behave” like a Physarum polycephalum, a unicellular organism endowed with surprising computational abilities and self-organizing behaviors that have made it popular among scientist and engineers alike (Adamatzky 2010) (Fig. 1). The trained GAN_Physarum is deployed as an urban design technique to test the potential of polycephalum intelligence in solving problems of urban remetabolization and in computing scenarios of urban morphogenesis within a nonhuman conceptual framework.

summary	This article provides support for Universities dedicated to Architecture and Urbanism to implement a Robotic and Digital Fabrication Unit, based on the experience of laboratories in Chile and Brazil. Public funding agencies often promote "technological innovation" associated with "Industry 4.0" which requires a conceptual understanding of this framework. The authors address the industrial robot as a central element of research projects associated with robotic techniques, and creative processes. In summary, this article discloses a repertoire of technological alternatives and installation considerations, with a detailed review on how to set up a robotic unit for academia, for teaching, research and design development, in the context of Southern Creative Robotics.

summary	This paper describes and reflects about a workshop activity in the field of Digital Manufacturing technologies to build responsive shelters that interact with their users and the environment. It addresses a teaching strategy intended to overcome tooling or the simple use of instruments and proposes instead to frame the production of objects using a new language, or a new operative strategy, directly linked to the production of the objects. It addresses a teaching strategy behind the workshop two main levels: first, by the development of technical skills by means of an operative action directly linked to the production of the object, and not apart from the action of making it (as in learning first and applying later). And second - and no less important -, it helped foster the maturation of critical thinking arising from the creation of a dynamic object of architecture - with moving parts and programmed to respond to its users.

summary	The following text reports a workshop activity performed at LAMO3d - Laboratório de Modelos 3d e Fabricaç?o Digital, PROURB FAU UFRJ that addresses the instrumental domain within the new digital manufacturing capabilities such as 3D printing, laser cutting and parametric design, and on the other tries to overcome the activity as a mere technical training. This concern implies a larger effort that goes towards the incorporation of a coherent discourse and has the ability to validate within the contemporary setting these new operative actions.

title	Urban Morphology and Solar Incidence in Public Spaces - an Exploratory Correlation Analysis Through a CIM System
source	García Amen, F, Goni Fitipaldo, A L and Armagno Gentile, Á (eds.), Accelerated Landscapes - Proceedings of the XXVII International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2023), Punta del Este, Maldonado, Uruguay, 29 November - 1 December 2023, pp. 1655–1666
summary	The walkability of open spaces has been highlighted in current discussions about the production of designed environments in urban contexts (Matan, 2011). To contribute to this theme, this work selects the environmental comfort of open spaces as its element of study. The production of urban space was investigated, specifically in regard to urban morphology, understanding that city design directly influences environmental comfort (Jacobs, 1996). This work addresses the geographic context of low latitudes, specifically in hot and humid climate zones of Brazil, and, in this context, according to NBR 15220 (national performance standards), shading is one of the main comfort strategies, so solar incidence was the approached environmental phenomenon. Thus, this work presents a digital system that performs exploratory analysis on the correlations between urban form indicators and environmental performance indicators, specifically solar incidence. The method consists of three steps: urban form modeling (1), indicator measurement (2) and correlation analysis (3). In the first stage, different spatial sections of a city in Brazil were represented in the digital environment (1). This work’s implementation instrument is based on a City Information Modeling framework (Beirao et al., 2012). Visual Programming Interface (VPI) and Geographic Information Systems (GIS) tools were used, in addition to a Relational Database Management System (RDBMS). Then, for each urban clipping, the values of morphological indicators and the incidence of solar radiation were measured (2). Based on the values of the indicators, an exploration of their correlation was carried out by statistical methods (3). The results of the correlation analysis and their correspondent scatter plots are presented. Finally, possible applications of the results for the creation of prescriptive urban planning systems are discussed, seeking to promote a sustainable urban environment.

summary	In the context of the fourth industrial revolution, not all regions have the same access to technology for project development. These technological limitations do not necessarily result in worst projects and, on the contrary, can stimulate creativity and human intervention to overcome these shortcomings. We report here the design of a small pavilion with scarce budget and an ambitious goal to qualify a space through tactical urbanism. We develop the project in a multidisciplinary partnership between academy and industry, designing, manufacturing and assembling Tornado Pavilion, a complex structure using combined HIGH-LOW technologies, combining visual programming with analog manufacture and assembly. The design strategy uses SIMPLEXITY with ruled surfaces strategy to achieve a complex geometry. Due to the lack of automated mechanical cutting or assembly, we used human expanded abilities for the construction; instead of a swarm of robots, we had a motivated and synchronized swarm of students. The pavilion became a reference for local population that adopted it. This process thus shows that less or almost nothing (Sola-Morales 1995), need not to be boring (Venturi 1966) but less can be much more (Kolarevic 2017).

summary	The use of computer-aided design combined with robotics and evolutionary principles of optimization, during the architectural design process, is discussed in this paper. The research is based on the examples of four case studies out of six projects designed during the Experimental Design Studio: ROBO Studio and a parallel seminar on optimization techniques on Architecture for Society of Knowledge Master course at Warsaw University of Technology, Faculty of Architecture. The project’s main goal was to combine robotic prototypes construction with an optimization process executed in parallel within one design procedure. The results of the course and the discussion about the impact of both factors on the architectural design process are presented in this paper.

summary	The paper presents an educational method used in teaching design of high-rise buildings in the city center. The author outlines the processes developed by students, the tools they used and the final results of design studio project and the supporting seminar, focused on exploring information processes in design. For the purpose of the design studio the students developed their own generative strategies that allowed incorporating optimization procedures into the design process. Within the framework of the seminar classes students developed individual optimization tools with the use of genetic algorithms in order to explore the search space and select the best possible architectural solutions for the specified criteria. The students used the above-mentioned tools mostly during the building's form-finding design stage or attempted to optimize just the building structure.

summary	When designing buildings in dense city centers, a very important step is to study the nearest surroundings of the plot, in order to enable the best possible placement of the building. Many aspects must be taken into account including urban, legislative, environmental and aesthetic factors. These factors, in particular the legislative ones, depend on local conditions. This article describes a methodology for the analysis of insolation of surrounding buildings in the context of local building regulations. A procedure is described that significantly accelerates this phase of the design process and permits integrating it with an optimization process concerning the location of the building on the plot. Examples of application of that procedure are presented and their limitations and capabilities are discussed.

title	Computing Rebar Layouts Aligned with the Principal Stress Directions: A Distance-Constrained Tracing Approach
source	ACADIA 2023: Habits of the Anthropocene: Scarcity and Abundance in a Post-Material Economy [Volume 2: Proceedings of the 43rd Annual Conference for the Association for Computer Aided Design in Architecture (ACADIA) ISBN 979-8-9891764-0-3]. Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 140-152.
summary	Reducing the consumption of carbon-intensive materials such as rebar steel is crucial to mitigate the environmental impact associated with architectural surfaces built with reinforced concrete. While digital fabrication and modern structural analysis tools offer opportunities to decrease rebar consumption, new computational approaches to create material-minimizing rebar layouts are required to effectively harness such potential. This paper presents a computational method to generate rebar layouts aligned with the principal stress directions on architectural surfaces. This method combines a rein- forced concrete design module based on current structural engineering codes, and a distance-constrained algorithm with adaptive seeding that iteratively traces evenly spaced rebars that follow a structurally optimal force flow. After its application to a flat slab and a folded shell, we demonstrate that the principal stress-aligned rebar layouts require up to 32% less steel than a single orthogonal rebar grid to resist an applied load. Our work highlights the potential of integrating design computation and structural engineering to advance research in the field of digital reinforcement, and to foster envi- ronmentally-aware design practices.

summary	3D sampling is a robust new strategy for exploring and creating designs. 3D textures are sampled and mixed almost like music to create new multifunctional surfaces and material microstructures (Figure 1). This paper presents several design cases performed using 3D sampling techniques, demonstrating how they can be used to explore and enhance product ideas, variations, and functions in subtle and responsive ways. In each case, design variations are generated and their mechanical behavior is evaluated against performance criteria using computational simulation or empirical testing. This work aims to promote creativity and discovery by introducing irregular geometric structures within trial-and-error feedback loops.
