title Samba Reception Desk: Compromising Aesthetics, Fabrication and Structural Performance in the Design Process
source Achten, Henri; Pavlicek, Jiri; Hulin, Jaroslav; Matejovska, Dana (eds.), Digital Physicality - Proceedings of the 30th eCAADe Conference - Volume 2 / ISBN 978-9-4912070-3-7, Czech Technical University in Prague, Faculty of Architecture (Czech Republic) 12-14 September 2012, pp. 255-263
summary The present paper describes an integrative design experiment in which different types of models were used in order to achieve a design that compromises aesthetics, lightness, fabrication, assembly and structural performance. It shows how an integrative approach, through the use of both virtual and physical models, can provide valuable feedback in different phases of the design and fabrication process. It was possible to conclude that the design method used allowed solving many problems and had a significant impact in the resulting object.

title Python on the Landscape of Programming Tools for Design and Architectural Education
source SIGraDi 2017 [Proceedings of the 21th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-956-227-439-5] Chile, Concepción 22 - 24 November 2017, pp.237-241
summary Currently most professional modeling and computer graphics software packages embed a scripting language. This is an early report on collecting data about software applications and coding tools geared towards the educational environment, preparing a listing for further evaluation and analysis of platforms. An increase in the adoption of Python as the embedded scripting syntax in many established tools can already be recognized, therefore the creation of educational materials on Python for design and architectural education merits further attention. Other insights on the educational potential of the available tools might be gained by advancing the data collection and evaluation work.

summary This paper evaluates the use of Scan-and-Solve plug-in for structural analysis in Rhinoceros’s environment. A reception desk parametrically modeled was evaluated with Scan-and-Solve and with Ansys. From the results, we concluded that the main difference between the programs is that Ansys allows more detailed definition of the connections between parts of the object. Besides the virtual models, the results were showed with a physical model printed with the rapid prototypes techniques. The paper describes the integration of parametric modeling, structural analysis and rapid prototyping procedures in the design process.

title Free-form Ceramic Vault System - Taking ceramic additive manufacturing to real scale

summary The use of Additive Manufacturing (AM) for the production of architectural components has more and more examples attesting the possibilities and the advantages of its application. At the same time we seen a fast grow of the usage of ceramic materials to produce fully customised architectural components using Layer Deposition Modelling (LDM) [1] techniques. However, the use of this material, as paste, leads to a series of constraints relative to its behaviour when in the viscous state, but also in the drying and firing stages. Thus, when ceramic dries, the retraction effects may be a barrier to the regular use of this material to build future architectural systems. In this sense, it is important to study the material behaviour and know how to control and use it as a primary construction material. To do that we present the challenges and outcomes of project Hexashade, a ceramic vault shading system prototype whose geometry and internal structure is defined according to the solar incidence. This paper explain how we expect to build a real scale self-supporting prototype.

summary The instantaneous nature of globalized information has brought places closer together and homogenized space, eliminating regional differences. Contemporary urban architecture and the technical-scientific- informational quality of the human-made environment innovates the rationality of the dominant actors in society. The field of telecommunications has developed substantially in the last 30 years, and today we are participants in a digital era, that has not only shortened distances but revolutionized the concepts of time and space. Telematics is a fundamental element of cities at the end of the millennium and has become a new instrument of social control. Electronic vigilance systems, as an application of telematics, are now widely used in cities, and a new urban space is being configured based on this dynamic. This paper is an introductory essay on the topic, which is essential in the understanding of urban spatial dynamics, and its objective is to point out fields for future research.

summary This paper discusses the experience of the initial phase of introduction of the BIM paradigm in the undergraduate program in Architecture and Urbanism (evening course) of FAUFBA. We started from the premise that BIM should be adopted gradually and integrated with the various subjects of the course, and should be initiated through the disciplines of graphic representation. The proposal for this course is presented and practices are discussed, as they were experienced in the discipline of Computing and Design II, which deals with this paradigm. It was observed that BIM process requires significant changes, as it encountered some initial resistance from the students. However, this approach increases the understanding of building and facilitates the project documentation. Furthermore, the understanding of the scope of the paradigm was crucial to the effective use of the adopted tool.

summary In the recent decades, the high-resolution remote sensing, through 3D laser scanning and photogrammetry benefited historic buildings maintenance, conservation, and restoration works. However, the dense surface models (DSM) generated from the data capture have nonstructured features as lack of topology and semantic discretization. The process to create a semantically oriented 3D model from the DSM, using the of Building Information Model technology, is a possibility to integrate historical information about the life cycle of the building to maintain and improving architectural valued building stock to its functional level and safeguarding its outstanding historical value. Our approach relies on an ontology-based system to represent the knowledge related to the building. Our work outlines a model-driven approach based on the hybrid data acquisition, its post-processing, the identification of the building' main features for the parametric modeling, and the development of an ontological map integrated with the BIM model. The methodology proposed was applied to a large-scale industrial historical building, located in Brazil. The DSM were compared, providing a qualitative assessment of the proposed method.

summary The purpose of this research is to develop a process capable of optimizing the capture of light in a circumscribed space, using a responsive system of skylights. Research is focused on the design of irregular dome-like pavilion spaces circumscribed by curved surfaces, but the envisioned process might be applied to other functional, formal, and spatial typologies. The design of the pavilion starts with the generation of a surface, later tessellated into a matrix of skylights depending on the geographic location and sun orientation. In the constructed pavilion, the skylights react to the variation of daylight intensity during the day to satisfy specified internal lighting needs. Simultaneously, the integration of conception and fabrication using digital tools (CAD-CAM) facilitates the construction of a non-standard, parametric geometry, thereby diminishing the costs of production and allowing for personalization, while assuring global sustainability.

summary The Building Information Modelling (BIM) technology enabled improvement in the design, construction and maintenance stages highly. In the field of existing buildings, including historical assets, this technology has not yet had the same impact. This paper presents a methodology to create an intelligent digital model for an outstanding building from modern architecture in Brazil using multiple reality-based technologies. The fusion of the different point cloud raw data generated a high-resolution Dense Surface Model (DSM), the base of an accurate and detailed parametric Model. This study demonstrated the potential of digital surveying, including low-cost sensors, and BIM for built heritage documentation.

summary This paper presents the example of the reconversion of an important tram station from the origins of electricity in Portugal that was still in use until the late 1990’s but became redundant since then. Its significant urban presence and the importance of preserving the memory of the old trams that were still in use some years ago in Lisbon, led to an innovative solution, combining public value and heritage protection. In 2011, the Lisbon City Council agreed to give the building and its site for university use, namely to be transformed into a student’s facility, as a study, leisure, recreational and cultural space of the IST, open 24h a day. This new university building, located just one block away from the traditional IST compound, was called IST Learning Center and extended the notion of campus outside its walls and into the city’s urban fabric.

source SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 377-384
summary This research investigates the cognitive design processes used by architects in conceptualizing design ideas using traditional and digital media. Data were gathered from: an initial design process of two groups of individuals using both design media to complete two videotaped isomorphic tasks; questionnaires; analysis of the retrospective verbal protocols about these tasks. The results indicate that the traditional media still presents advantages against the digital media due to limitations on the state of the art of hardware and software and on the lack of understanding and well handling of the computer by the architects. Some advantages related to the use of traditional media were: it furnishes the architect with more comprehensive perception regarding the relationships between visual, spatial and organizational aspects of the design process, whilst stimulating the production of several alternative solutions, avoiding, therefore, premature crystallizations of design solutions, and a more comprehensive understanding of the design tasks.
