summary Humanity is currently facing an environmental crisis driven by our reliance on fossil fuels and our indiscriminate use of global resources. To address this we investigate the development of a sustainable new material, nano-cellulose. Nano-fibrillated Cellulose (NFC) is a highly renewable material processed from wood fibres. In this research we present a new method for processing renewable Nano-fibrillated Cellulose into a bulk material. Presently, traditional wood fibre is utilized extensively; it is used in the production of paper, clothing, and buildings. This research asks if wood fibre could be utilized in applications that go beyond its traditional uses? Using an iterative approach, the research reveals the challenges of working directly in the processing and production of nano-fibrillated cellulose, a high-performance bio-polymer requiring no adhesives and no petrochemicals as a finished product. The paper presents these experiments and discusses the feasibility for using nano-cellulose in building products.

summary This paper analyses how architecture became a pioneer discipline in digital interactivity research. It describes how that pioneer research derives from a lineage of researchers whose work spans more than two decades beginning in the early fifties. Military funds enabled the creation of the first computer graphic interfaces that evolved into a "drawing machine", the first interactive CAD, that made possible the role of architecture as a pioneering discipline in interactivity research. It is expected to demonstrate that the same architecture that nowadays uses mainly interactive digital design was one of first disciplines to research interactivity addressing a gap in the study of the link between architecture and interactivity.

source SIGraDi’2000 - Construindo (n)o espacio digital (constructing the digital Space) [4th SIGRADI Conference Proceedings / ISBN 85-88027-02-X] Rio de Janeiro (Brazil) 25-28 september 2000, pp. 38-40
summary In the earl’s nineties, when the www start to be popular, it had a configuration given by the academics. This sites worked as a data base where you could get specific information. In a very fast way the commercial sites get in to the www just to be there with a strong institutionally presence. In the middle nineties the possibility of incorporate sound and video to the Internet give the possibility to the appearance of entertainment sites as an option for television. During the last year we saw a new change in the digital landscape of the Internet, the commercial sites start to move trough a new concept: the e-commerce. The WWW is not just a way of communication, it is a distribution channel. In a society where the information is one of the most required commodity, the bit is not just information, is the digital tool for the new global economy. Because the laws of the market does not agree with the anarchic and chaotic spirit that give the first breath to the net of nets, this phenomenon make a great impact in the Internet. The subject of this work is the study of this phenomenon and to analyze the behavior of this “new kids on the Net” and the alternatives facing the advance of the market trough the right of free access to information.

summary Current research departs from the WikiHouse an open-source constructive system that enables self-construction and customization in engineered wood. The public platform favours the design and construction using CNC technology and digital manufacture. However, the system application and form vocabulary are bounded to orthogonal profiles geometry. Current research intended to automate the system in an algorithm and to expand the design to curved geometries, what was tested using digital fabrication in 1:1. The system developed allows the personalization of solutions of shell-like geometries that might use less material in more robust solutions, opening new design possibilities for the system.

summary This paper addresses the impact of digital support on the management and organization of information, with the aim of demonstrating its usefulness in connecting data during collection and systematization processes in scientific research. The research methodology involves practical simulation, correlating content obtained from a systematic literature review with the functionalities of the Obsidian 1.3.5 software. The results highlighted the advantage of a more intuitive visualization of the interconnection between information and the predominant identification of significant key topics, allowing a clear understanding of the main areas of focus in the articles analyzed. The mapping also made it possible to group themes by their affinity, revealing thematic clusters and facilitating the identification of recurring patterns. In this sense, the study emphasizes the benefits for researchers of incorporating digital resources into the process of development of scientific productions.

title Sistema interativo para análise das relações de afinidade entre o círculo e a elipse [Interactive system for analysis of the circle and ellipse affinity relations]
source SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 258-260
summary This paper will try to establish a dialogue between the process of rational geometric construction and the intuitive process of discovering shapes. This will involve: a geometric principle that works as a geometric generation law and two interactive macros. The geometric principle is the affinity between circles and ellipses. The macros, developed in VisualLisp languagefor AutoCAD, allow the students to construct 3D abstract structures. In order to provide support for the student in the task of analysing the 3D structures a methodology has been established to classify shapes giving each one an alphanumeric string. The string reflects the transformation order during the creation of each spacial structure. With the aid of interactivity it is intended that this exercise in discovering space creates a tension allowing the rational and intuitive states of mind overlap.

title The Nazca Lines and their Digital Architectural Representation
doi https://doi.org/10.52842/conf.caadria.2007.x.r9m
source CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary This paper relates to a digital architectural design experience in 2005 for the Nazca Competition. Nazca is an archaeological site situated about 400 kilometers south of Lima, Peru. It is a large desert with gigantic millenary geoglyphs carved on the surface, which can only be seen clearly from above. The Nazca geoglyphs are made up of hundreds of lines, spirals and triangular plazas, as well as zoomorphic figures like birds, fish, spider, etc. The Nazca Competition asked for an observatory-lodge of approximately 1.000m2 with 20 rooms, communal bathrooms, supporting areas and an observatory tower of at least 100 meters. The observatory-lodge was designed using a digital representation technique called "Genetically Constructed Structures". The structure was created using the geometric principle of the affinity of two conic sections: circle and ellipse. The form was produced transforming the circle and the ellipse by performing basic geometric transformations (translation, rotation, reflection and scaling). According to this technique, the sequence of transformations was codified in the form of an alphanumerical string, metaphorically named the "DNA structure". The code was inserted as extended data into the entities which shaped the structure profiles. The algorithms were programmed with AutoLISP language. The "DNA code" allowed the structure to be constructed and deconstructed from any point, generating many different forms, to be studied and compared. One year later, the same 3D model was used to test another digital technology called "musical box" where their geometrical points are captured, read and translated into musical parameters, generating music. In this paper we will present the graphical form of the tower as well as the music associated.

title Fachada Cinética: aplicando aritmética modular para controlar padrões de movimento [Kinetic facade: applying modular arithmetic for controlling movement patterns]
source SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 388-391
summary This article reports the experience of creating a support application for designing kinetic facades. The tool´s goal is the creation of a visual simulation system that permits full control over the movement of geometric patterns. In this case, we try to control the variation of polarized glasses used on architectural facades. The study presents a modeling technique of geometrical grids created and controlled by modular arithmetic operations. The programmed algorithm allows performing periodic geometric patterns. The research is aimed at formalizing a library of patterns and types of possible movements through ratings and an abstract symbolic representation.

title A framework for speech-oriented CAD and BIM systems
source The next city - New technologies and the future of the built environment [16th International Conference CAAD Futures 2015. Sao Paulo, July 8-10, 2015. Electronic Proceedings/ ISBN 978-85-85783-53-2] Sao Paulo, Brazil, July 8-10, 2015, pp. 381.
summary This article discusses the development of a Speech Oriented Graphics Interface embedded in CAD and BIM software. The aim is to provide the means to work with complex 3D BIM models with minimal touch operations. We can cite the growing need for tools and user interfaces to assist designers in handling complex models, minimizing the risk of producing changes accidentally. In this area, the integration of a graphical database in BIM applications can be seen as an advantage over traditional CAD applications. However, we can note a difficulty in this integration, due to the need to maintain the constant levels of mental concentration required in order to effectively manage a larger inter-connected graphical database. Specifically in this area, voice interfaces can help by avoiding the need of "touch" to work with the 3D models, looking for improving its robustness and consistency. In addition, SR is used in order to reduce cognitive stress among the users, trying eliminating the need to memorize and remember commands, names and locations in GUI interfaces.

title Explicitando a estrutura do prédio em modelos BIM [Giving an explicit definition of a building structure in BIM models]
source SIGraDi 2016 [Proceedings of the 20th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-956-7051-86-1] Argentina, Buenos Aires 9 - 11 November 2016, pp.459-465
summary This paper presents an API implementation for a BIM program written in .NET platform. The goal of this application is to launch the structure of a building automatically. The automation creates and controls the building's structural elements types using external text files with a dual purpose of being the source of information and to be the explicit description of the project. Our target is to create a definition of semantics that integrate the application with a voice user interface (VUI). The present version of the work is focused on a conventional and compact building type.

title BIM Ontology. Some Aspects of Project Knowledge: the Building, IFCs and STOs.
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. 433–446
summary This article reports on the methodology for creating an ontology constructor application (API). The API writes the ontology in OWL (Ontology Web Language). To implement the system, two elements were used: 1) a set of Excel spreadsheets that contain the hierarchical and logical structure of classes, object properties, data properties, and instances for testing purposes. These elements will define the ontological axiomatics within a well-defined BIM domain; and 2) a mechanism for processing the spreadsheets, programmed in Dynamo with DesignScript language. The mechanism reads the content of the spreadsheet and writes it in OWL format using the Manchester syntax. The work is introduced remembering some key concepts present in research carried out in this field of computer science during the 80s and 90s. The use of ontologies aims the integration of BIM data and Semantic Web, to operate digital construction environments within the Open Linked Data paradigm.

summary This research investigates the adequacy of the contemporary professional formation to professional practice in the construction market. The work investigates the teaching of building and structures design in schools of architecture and civil engineering in Belo Horizonte. There is evidence that the use of contemporary information technology such as BIM (Building Information Modeling) enables integrated teaching of architecture and engineering, allowing simultaneous work. The hypothesis is that there is a mismatch between contemporary teaching and practice and methodological changes seeking simultaneous practice, respond adequately to contemporary assumptions of learning. The confirmation of this hypothesis subsidizes developments for future research.
