summary Recently, prototyping enabled by CNC technology has found its way into design practice where concepts can be quickly and economically tested through multiple design iterations that closely approximate the realities of oneto- one construction. This has lead to the promise of renewed research in tectonics and constructional techniques where the traditional concepts of craft and the joint, that were once married to the hand, can be rediscovered through the agency of mass customization. If we apply the lineage of the trait—a representational and cognitive tool to marry complex form with the exigencies of construction—pedagogical approaches can be developed that extend the current interest in intricate surface, structural morphology and geometry towards a robust materiality rooted in componentry, the joint, and part-to-whole relationships. This paper will introduce several threads from the twentieth century that have informed these tendencies in contemporary design practice, emerging from the well spring of Viollet-le-Duc. The thesis is supported by undergraduate model-based research employing digital design and fabrication techniques.

summary En informatique graphique, la méthode la plus courante pour saisir un bâtiment consiste à dêcrire et à stocker en base de données les "pleins": les murs, planchers, composants. Cette procédure est vite fastidieuse, et ne permet pas réellement une véritable conception assistée par ordinateur. KEOPS expérimente une autre méthode qui consiste à décrire l'esquisse par ses "vides", c'est-à-dire les volumes des locaux en trois dimensions. Le logiciel opère automatiquement la transformation "filaire" en composants et ouvrages du bâtiment en exploitant un savoir technologique. Le benéfice? La réduction spectaculaire du temps de saisie et un logiciel de C.A.O. enfin opérationnel en bâtiment.

summary L'institution architecturale est organisée à partir du postulat d'une incommunicabilité de l'architecture ("I'espace indicible" de Le Corbusier, par exemple), ce qui ne facilite pas l'enseignement ni l'exercice professionnel. Comme l'ont montré divers travaux théoriques, ce postulat n'a rien de nécessaire, bien qu'il joue un rôle institutionnel historiquement situé. Une activité pratique de communication de l'architecture par la vidéo conduit à la même conclusion: bien des opportunités existent d'exploiter les techniques médiatiques contemporaines pour les mettre au service de l'architecture, de son enseignement et des pratiques professionnelles. La présentation s'appuie sur quinze ans d'expérience d'enseignement et de production de vidéos dans l'Ecole d'architecture de l'Université de Genève ayant permis la réalisation d'une centaine d'émissions sur l'architecture, la construction et l'urbanisme.

summary Mais ou en est l'architecture? Elle mute. Le grand air frais qui avait été amené par le Mouvement .- Moderne lorsqu'il était jeune, entre les deux guerres et quelques années après la guerre, s'était tiédi et avait fini par servir d'alibi aux pires médiocrités industrielle et bureaucratique: c'était toujours la faute de la Charte d'Athènes... Ceci reposait sur toutes sortes de contre-vérités et de malentendus qui ne sont pas encore tous levés actuellement et sont encore souvent enseignés dans nos écoles.

summary Nous qui devons enseigner à nos élèves les techniques du dessin traditionnel avons trop souvent recours à des recettes et normes mnémotechniques venues des ateliers et studios d'art traditionnels. De telles stratégies, souvent personnelles et intransférables, s'appuyant sur de longues heures de pratique, sont difficilement assimilables pour des élèves qui ne disposent pas de tant de temps pour s'entraîner, ni d'une telle expérience perceptive; dans le meilleur des cas, il en résulte un dessin stéréotypé ou, s'il est brillant, c'est que l'élève savait déjà dessiner. Comme nous considérons que le dessin traditionnel et le CAD sont les deux outils fondamentaux qui permettent à tout architecte d'exprimer ses idées, il nous a semblé opportun de chercher les points communs entre ces deux disciplines. Dans un discours illustré de dessins d'auteurs divers, nous essaierons de démontrer comment, si nous utilisons exactement les mêmes critères que ceux qui régissent un ordinateur dans l'interprétation de ce qu'il voit, le résultat de la représentation est pleinement expressif et efficace. Si nous sommes capables de rationaliser cette méthodologie et de la transmettre à nos élèves, nous aurons répondu à notre double objectif: leur enseigner à dessiner par des techniques traditionnelles, dûment rationalisées et comprendre un peu mieux le fonctionnement des ordinateurs.

summary What sort of interfaces will allow, in the future, to manage the evolution of information and knowledge generation? What new scenarios would emerge in contemporary architecture when the access to a multidimensional architectural database is open and it is written and visited by anyone, anywhere in earth? Internet evolution is fast and unpredictable, propelling deep changes at different levels of our society. Spinoffs, unexpected outcomes are result of those changes, unfolding uncertain, unstable scenarios. This paper discusses the question of what could be the way to organize the process of registering, documenting and online publishing, native digital, three-dimensional content of Architecture, assuming the critical issue of information integration.

title The Use of Diagrammatic Reasoning to Aid Conceptual Design in Building Information Modeling (BIM)
doi https://doi.org/10.52842/conf.ecaade.2021.2.039
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. 39-48
summary Architectural design is an intellectual activity where the architect moves from the abstract to the real. In this process, the abstract represents the logical reasoning of how architectural form is configured or structured, while the real refers to the final physical form. Diagrams become an integral part of the conceptual design stage because they mediate between those two realms. Building Information Modeling (BIM) can reallocate the effort and time to emphasize conceptual design. However, many consider BIM a professionally-oriented tool that is less suitable for the early design stages. This research suggests that architectural design reasoning can be achieved using constraint-based parametric diagrams to aid conceptual design in BIM. The study examines several techniques and constructs a framework to use diagrams in the early design stages. This framework has been investigated through Villa Stein and Citrohan House by Le Corbusier. This study addresses two roles of diagrams: the generative role to create various design solutions and the analytical one to conduct an early performance study of the building. Our research contributes to the discussion on the ways designers can use digital diagrams to support the architectural design process.

summary Brazil has so many historical cities with important architectural heritage. Some of them are remains of the colonial times and aggregate beautiful buildings such as, palaces, public buildings and churches in baroque style, legacy of the Portuguese colonization. Despite of its cultural value, most of these building sets are under several kinds of threats. This paper discusses about the experience on digital photogrammetric restitution of the building façades of Pelourinho, a neighborhood in the historical center of Salvador, the capital city of the State of Bahia. The architectural documentation is an important way to preserve and safeguard its memory, besides being an effective educational process about the meaning of preservation and cultural heritage.

summary This paper presents and discusses the relationship between the concepts of Smart Cities and City Information Modeling (CIM). It conveys the notion that these are complementary and not competing concepts, as one might think at first glance. On the other hand, the paper demonstrates the importance of these concepts to overcome the challenges to the cities of the 21st century, from findings contained in official documents published by the United Nations (UN), to analyze the growth of world population and the emergence of new cities to house population groups. Finally, this paper argues that the CIM with an inducing factor for the Smart City is an important resource to help improve the quality of life in cities.

summary This paper describes the Pelourinho Project realized past July in Salvador, during the 1st International Conference on 3D Laser Scanning for Heritage Documentation. The Pelourinho located at the historic center of Salvador, is an impressive wide set of buildings listed by UNESCO as World Heritage. The text contains a quickly overview about the 3D laser scanning technology, shows how data are captured and what they stored and what they means. The 3D laser scanning model, another kind of 3D geometric model is called point cloud and represents an excellent way to store data of some particular constructions. Because its irregular shapes it is very arduous to survey and represent these constructions by any other method. The point cloud model is an excellent way to represent with integrity and accuracy these particular complex shapes like the colonial baroque churches in Brazil. [Full paper in Portuguese]

title Hybrid Art > Synthesized Architecture
source SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary This paper investigates possible intersections between some contemporary artistic modalities and architectural practice. At first, it describes and discusses different uses of art in architectural history. Through the analyzes of Le Corbusier’s artistic and architectural practices, it observes the limits of looking at art as only ‘inspiration’ for architectural form and points to the necessity of surpassing this formal approach. More than bringing pictorial ‘inspiration’, art, as a experimental field, can change our architectural procedures and approaches - a much richer and powerful addition to the development of architecture. It discusses then, the confluence of architecture, information and communication technologies. Very commonly present in our contemporary life, not only on the making of architecture – computer drawings and modeling of extravagant buildings – nor in ‘automated rooms’ of the millionaire’s houses. Televisions, telephones and computers leave the walls of our houses “with as many holes as a Swiss cheese”, as Flusser has pointed. The architecture has historically manipulated the way people interact, but this interaction now has been greatly changed by new technologies. Since is inevitable to think the contemporary world without them, it is extreme urgent that architects start dealing with this whole universe in a creative way. Important changes in architecture occur after professionals start to research and experiment with different artistic medias, not limiting their visions to painting and sculpture. The main hypothesis of this paper is that the experiments with new media art can bring the field of architecture closer to information and communication technologies. This confluence can only take form when architects rise questions about technology based interaction and automation during their creative process, embodying these concepts into the architecture repertoire. An educational experience was conducted in 2007 at UFMG Architecture School, in Brazil, with the intention of this activity was to allow students to research creatively with both information technology and architecture. The students’ goal was to create site-specific interventions on the school building, using physical and digital devices. Finally, the paper contextualizes this experience with the discussion above exposed. Concluding with an exposition of the potentialities of some contemporary art modalities (specially the hybrid ones) in qualifying architectural practices.

doi https://doi.org/10.52842/conf.acadia.2000.017
source ACADIA Quarterly, vol. 19, no. 4, pp. 17-24
summary Some views of design are the act as puzzle making, problem solving, evolutionary, and decision-making. All these focus on form generation as constructive, therefore characterizing design as a path-planning problem through a space of possibilities. Design problems consist sets of information divided into initial, intermediate, and goal states. Design in its simplest state consist of a set of operators, sequences (or paths) between initial and goals states. In this paper, I present design algorithms for Le Corbusier because of his distinct compositional techniques particularly for his “White Villas” in which some elements have been identified to recursively occur.

summary This paper tries to evaluate the quantitative e qualitative aspects of the uses of the computational simulation for the analysis of enclosed environments light designs, and its feasibility in teaching in Architectural and Urbanism courses. The importance of this paper is associated with the determining of the illumination levels and its effects. Simulations were made with the Lightscape software in a specific room and their results were compared with the experimental measurements taken in that place. From this comparison it was possible to make the analysis of the software characteristics and to evaluate the advantages or disadvantages of its uses. The results confirm its feasibility as a tool for illumination simulation and its adequate uses in the teaching of environmental comfort. The good correlation achieved in visual effects derived from the lighting design and also the information of values related to illuminance and luminance for the simulated space support this affirmative.

summary Computer-Aided Design (CAD) has become more and more part of the common architectural practice. Some designers have explored (in the past) different aspects, especially formal ones, allowed by these new information technologies. This paper’s goal is to explore the invention that would be specific to this new architectural practice. The hypothesis is to go back to the specificity of the image and to examine its evolution. This analysis will be done with reference to the « cycle of images » of the French philosopher Gilbert Simondon, described by means of stages and levels. This particular way of thinking will allow us, besides an overview of all those images in a genetic diagram, to reveal what can enable the passage from one level to another. We call this : “invention”.

summary Le Corbusier notes in Vers Une Architecture that, because we look at the creation of architecture with eyes which are 5'-6" from the ground, it is imperative to "deal with aims which the eye can appreciate, and intentions which take into account architectural elements." (Le Corbusier 1927) Architecture is a three-dimensional entity that we experience as much through movement as repose. Therefore, it is essential that the computer technology used to design architecture enables the consideration of both aspects of this experience. This paper presents several ways in which animation is used to enhance the design process.

summary Cet article est consacré à la modélisation procédurale de configurations architecturales. Les outils de CAO actuels reproduisent et figent la pratique traditionelle du projet architectural, leurs modèles de représentation sous-jacents sont considérablement éloignés de la représentation usuelle de l'objet architectural. Il nous apparaît que les modes d'accès et de constitution "alternatifs" du modèle informatique (description textuelle et modélisation procédurale) représentent un champ d'expérimentation privilégié susceptible de questionner ces problèmes de représentation du savoir architectural. Nous commencerons par l'examen de modélisations par description textuelle (notamment de façades néoclassiques et de l'architecture palladienne) pour ensuite nous intéresser à une série de modélisations procédurales à base de connaissances architecturales. Nous verrons enfin comment cette réflexion, dans un cadre pédagogique, confronte nos étudiants à la fois à l'analyse architecturale, à une approche de la programmation structurée ou orientée-objet ainsi qu'à une utilisation "critique" des outils de conception assistée.
