Abstract and Figures

Parametric design and digital fabrication are becoming an ubiquitous tool to contemporary architecture and implies a different method of detailing. With this new perception of the contemporary detail we have developed a façade sun shade using fractal geometry as a generative system. Fractals are complex shapes generated with simple rules, so is relatively easy to change the final geometry when we work with parameters. The design process made possible the creation of many solutions using parametric definitions. Those solutions were physically modeled using rapid prototyping which we consider as an essential tool to the design process. This method also involved analysis and testing of the design using software and the physical models. With this project it was possible to conclude that when working with digital fabrication architects need to incorporate a new set of skills, and that collaboration between professional is extremely important.

LAMO seminar/workshop >> Em busca da forma, sistemas generativos (Form finding & generative systems) sought to deepen the theoretical and practical development of generative algorithms in design. It proposed to explore the advances of mathematics at the end of the 20th century, namely information theory and general systems theory. These advances provided a new set of techniques to find design solutions. Although these techniques have already been applied in areas such as engineering, graphic design and urbanism —given their mathematical and computational nature — their application in architecture is still scarce. This event sought to translate computational techniques, such as cellular automata, L-systems, genetic algorithms and shape grammars, for generative form finding tools. The idea was to understand through experimentation how these techniques can be applied to solve design problems. The event was preceded by a research and was supported by an international scientific committee, gathering a group of researchers experienced in the referred techniques. This article describes the methodology, studying the results, evaluating the potentialities and limitations of each technique, considering future developments. This is a publication following the presentation at the 4th Formal Methods of Architecture in Porto in 2018.

A modelagem paramétrica baseada em objetos constitui paradigma natural e essencial da Modelagem da Informação da Construção (BIM), potencializando a automação e contribuindo para a manutenção da consistência entre as informações do modelo. Estudos de sua potencialidade e aplicação prática ao projeto estrutural são importantes para a difusão do conceito entre os profissionais desta disciplina. O presente trabalho visa explorar a modelagem paramétrica baseada em objetos em BIM, no contexto do projeto de estruturas, por meio do estudo de caso de fundações tipo tubulão, utilizando a plataforma Autodesk Revit. O delineamento do estudo de caso segue: (i) apresentação de conceitos e etapas da modelagem paramétrica baseada em objetos no Revit; (ii) detalhamento do processo de modelagem paramétrica baseada em objetos de uma Família de fundações tipo tubulão; (iii) aplicação da Família modelada no contexto de um modelo real. O trabalho apresenta conceitos, estratégias e práticas para a modelagem paramétrica de elementos estruturais, além de um mapa de processo que descreve a utilização de objetos paramétricos no contexto de um projeto estrutural que tire proveito da modelagem paramétrica baseada em objetos em BIM. Foi observado que a modelagem paramétrica baseada em objetos em um ambiente BIM para projetos estruturais é tecnicamente viável e apresenta vantagens e benefícios a serem explorados pelos profissionais da área. Entretanto, a estrutura rígida de classes a nível de categoria na plataforma Revit restringe a modelagem paramétrica baseada em objetos oferecida exigindo soluções paliativas.

Este trabalho aborda a confecção e avaliação de elementos de fachada que utilizam as características da geometria fractal, e tem como objetivo averiguar se estes elementos potencializam a utilização da luz natural. Desta forma, dez elementos de fachadas foram desenvolvidos a partir de regras de fractais lineares, utilizando ferramentas de modelagem tridimensional, paramétricas e plug-ins, que permitissem recriar algumas das regras de composição dos fractais. Esses elementos foram submetidos em uma composição homogênea em um ambiente virtual construído para simulações dinâmicas, sendo avaliados nas orientações Norte e Sul. Seus resultados foram agrupados em planilhas e gráficos, possibilitando uma avaliação individual de cada composição presente nos diferentes elementos. Os resultados encontrados mostraram que os elementos desenvolvidos com as características fractais apresentam respostas diferenciadas para cada elemento e iterações, demonstrando que a utilização desta geometria como uma forma de controle solar, pode potencializar as condições lumínicas do ambiente interno, além de ampliar o leque de alternativas para o design de componentes compositivos para fachadas. Com o algoritmo desenvolvido, também pode-se selecionar os componentes com mais potencialidades para a determinada localidade simulada, permitindo que em futuros estudos ele possa ser alterado em diferentes parâmetros, potencializando suas atribuições como elemento de fachada.

Considerando a importância do controle da radiação solar e admissão da luz natural no desempenho das edificações, os elementos de controle solar, quando corretamente aplicados, podem contribuir significativamente com o conforto e a eficiência energética no ambiente construído. Paralelamente, destaca-se na produção arquitetônica contemporânea o crescente emprego de ferramentas computacionais no suporte às decisões de projeto. Nesse contexto, o objetivo desta pesquisa é analisar a admissão de radiação solar e o desempenho lumínico de elementos de controle solar desenvolvidos com modelagem paramétrica e algoritmos evolutivos. A metodologia foi organizada em quatro etapas: (1) modelagem paramétrica dos elementos de controle solar; (2) simulações computacionais referentes à admissão de radiação solar e ao desempenho lumínico; (3) otimização através de algoritmos evolutivos; e (4) análises de mascaramentos gerados por simulação computacional. Os aplicativos utilizados foram a suíte de modelagem paramétrica Rhinoceros3D+Grasshopper; o plug-in de desempenho ambiental Diva-for-Rhino; a ferramenta de algoritmos evolutivos Galapagos Evolutionary Solver; e as ferramentas de geometria da insolação do plug-in Ladybug. Os resultados demonstram que os elementos desenvolvidos foram capazes de controlar seletivamente a admissão de radiação solar, além de melhorar a distribuição da luz natural nos ambientes de análise, destacando-se respectivamente a importância dos componentes direcionais e horizontais. Por fim, os mascaramentos demonstram, complementarmente aos resultados das simulações, que a compreensão da geometria da insolação apresenta-se imprescindível para o desempenho dos elementos de controle solar.

The Aviva Stadium, Dublin, is the first stadium to be designed from start to finish using commercially available parametric modelling software. A single model in Bentley’s Generative Components was shared between architects and engineers, which allowed the optimised design of form, structure and façade. The parametric software was extended where necessary to integrate with structural analysis and to automate fabrication. By reducing the overhead associated with design iterations, this approach allowed detailed exploration of options and early identification and resolution of potential problems. In this paper, the authors add to the body of scientific knowledge by describing in detail the methods which led to the construction of the Aviva Stadium.This paper is written in light of the completed building and provides information on the generation and control of the envelope geometry, development and analysis of structure and documentation for construction. Whilst these components have been discussed independently previously, here these aspects are drawn together for the first time and are presented alongside thoughts on the manufacturing and construction processes from the project architect.

Fractal architecture is a complex and elusive concept that can mean different things in different contexts. Drawn from architecture, mathematics and complexity science – and with diverse origins and applications in each discipline – fractal architecture is of interest both as an isolated concept and as an example of how knowledge is developed and exchanged between disciplines. The objectives of the present work are essentially epistemological; they are concerned with tracing and critiquing the way in which ideas shift between disciplines and the hybrid concepts that are formed in this process. The central thread traced through this work is fractal architecture and the primary knowledge domains in which it is investigated are architectural theory, design and mathematics. In the process of unravelling this thread, the present work seeks to answer the question of whether or not, from any perspective, fractal architecture is a useful or meaningful concept?

The paper introduces and discusses current developments in architectural discourse, design theory, digital design models and techniques and their relations to design pedagogy. The evolution of design knowledge in architectural theory and praxis is explicated and its implications for required changes in design education are presented. The theoretical influence of architectural concepts is presented through historical references in digital architecture. This structure of design concepts is proposed as a medium of design education. An experimental design studio on: ‘Design as research: the exploration of digital architectural concepts’ is presented as a pedagogical framework for educating the digital architect and a series of research and design programs carried out in an experimental design studio demonstrates this framework.

This article communicates results of an experimental pedagogical strategy aiming at both, introducing and taking advantage of new technologies in an architectural design studio. One of the reasons for the notorious unfriendliness of CAD software to the design process comes from the attempt to imitate traditional pen and paper design on the computer. While the whole process could be completely different when performed in a digital environment offering powerful form generation and knowledge modelling possibilities. the proposed teaching method is based on the following principles: (1) emphasis on new methods of designing made possible by the use of computer; (2) communicating the design process, and not only the final result; (3) exploring parametric design for generation of different formal expressions of a design concept; (4) using visual programming to create inter-object relations, etc. A comparison of this experimental approach to other approaches used in design studios (digital or traditional), proves that the architectural results obtained are largely related to the chosen medium and the tools of work. In our opinion, this teaching approach proves to be promising for introducing considerable qualitative changes in the architectural profession, and this way in our built environment as well.
