title Architectural shape generating through environmental forces
source T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 875- 886
summary In this paper we present a new parametric approach based on environmental constraints, in order to generate digital models of architectural shape, directly within a three dimensional geo-referenced environment. Those constraints may be regarded as force fields with a specific spatial dimension. The system allows user, through implementation of specific generative procedures, to manage interactive architectural design processes. The designer is able to explore all possible infinite scenarios and the various possible design alternatives, by changing the parameters values and verifying in real time the results of the changes. Two experiments are presented.

summary This project examines a non-traditional method of construction generated through a digital design process that leverages digital fabrication techniques related to masonry construction. Where as architects’ use of computers first affected shape and structure, it is now additionally affecting material, construction, and craft. This design proposal explores these concepts through the production of a wall using simple configuration and reconfiguration of a repeated module adaptable to differing and unique contexts and site conditions. The masonry module is designed and built through the exploration of a CAD-CAM process. The prototypes produced investigate the repetition of a single module unit, manipulated and interlocked resulting in a continuous surface that is more than just the sum of its individual parts. The material, construction and craft of each unit informs and challenges the entire project to question the making of the masonry module into a wall.

summary We investigate the recent coincidence of rapid global urbanization and unprecedented formal freedom in architectural design and ask whether this coincidence is an uneasy one. To study an extreme case of the new exotic geometries made possible through CAAD, we employ algebraic surfaces to experimentally design architecture in an university-based research and experimental design project. Such surfaces exhibit unprecedented complexity and new geometric and topological features yet are highly sound and harmonious. We continue and extend our research presented at the eCAADe 2009 conference in Istanbul.

summary We describe the exploration of the manifold novel shapes found in algebraic geometry and their application in architectural design. These surfaces represent the zero-sets of certain polynomials of varying degrees. They are therefore very structured, coherent and harmonious yet at the same time geometrically and topologically highly complex. Their application in design is mostly unprecedended as they have only recently begun to become accessible through novel software tools. We present and discuss experimental student design and research projects where shapes found in algebraic geometry were developed into pavilion designs. We describe historic precedents for the inspiration of art and architecture through mathematics and show how algebraic surfaces can be used to expand architects’ sculptural vocabulary, make the utmost of three-dimensional sculptural qualities, employ shapes that have a strong internal structure, transcend the imaginable and explore polynomials as a new kind of shape-making tool.

title An Urban Grammar for Praia: Towards Generic Shape Grammars for Urban Design
doi https://doi.org/10.52842/conf.ecaade.2009.575
source Computation: The New Realm of Architectural Design [27th eCAADe Conference Proceedings / ISBN 978-0-9541183-8-9] Istanbul (Turkey) 16-19 September 2009, pp. 575-584
summary This paper presents a shape grammar for planned urban spaces intending an implementation for generative urban design. This implementation will form part of an urban design support tool defined to formulate, generate and evaluate urban designs. The goal is to formulate urban program descriptions according to context conditions using a description grammar and generate alternative design solutions using a shape grammar. The generation is guided by several evaluation processes performed by an evaluation module. In this paper we are focusing on the definition of the generic shape grammar using an existent urban plan as a case study. The aim is to encode the design moves of the urban designer into generic grammar rules amenable for specific instantiations through the customization of rule parameters.

title Grammars of designs and grammars for designing - grammar-based patterns for urban design
source T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009
summary Analytical work has demonstrated the potential of shape grammars for capturing rules embedded in existing design styles, and generating designs within such styles that match given design contexts. However, the creation of grammars for new design styles, from exploratory rules to design synthesis, remains elusive. The combined use of patterns and discursive grammars is here proposed as a way of encoding the semantics behind recurrent urban design operations and enable the development of a tool to support the creation of new grammars. The idea is that by exploring the combination of generative patterns designers may arrive at new grammars.

title Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
source Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 247-264.
summary The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called “gingerbread houses”, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

title Digital Craft Meets the Ancient Art of Ceramics: Would the Bauhaus Approve?
source SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary The Bauhaus was founded upon the controversial premise that emergent mechanical processes offered new and creative ways to explore materials. Today, we encounter equally tendentious scenarios where the designer often appears one step further removed—automated CNC machines are driven by computational machines. Like the early activities of the Bauhaus some view digital pursuits with suspicion; however, digital design/fabrication is the “Nächster Bauhaus Bewegun” offering opportunities for design innovation equal in significance to that of the Bauhaus. This paper partially examines the theoretical implications of digital design/fabrication, then presents a collaboration between an architect and artist re-examining the architectural cladding possibilities using digital tools to shape one of mankind’s most venerable materials—ceramics.

source T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 105-118
summary This paper deals with 3D modeling of complex architectural elements for virtual 3D scene reconstruction based on images or point clouds. It presents a new method at the opposite of classical photogrammetry and lasergrammetry techniques: parametric components are created and then adapted to the measured data. We have conceived and developed a parametric shape generator tool for virtual 3D reconstruction of cultural heritage monuments. We present the geometrical study on the cupola shapes with all their diversity. It is illustrated with the Suleymaniyé Mosque in Turkey. The results are promising. The modeling time is greatly reduced.

source SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary The objective of the present research was to study the use of animation techniques as a tool for the design process. The study started with a literature review about the different possible applications of animation techniques in architectural design. Four main categories of applications were found: (1) space representation and “walk through”, (2) simulation of articulated elements and kinetic structures, (3) visualization and analysis of functional aspects of the buildings, such as circulation and fire escape, and finally (4) the generation of novel shapes. The second part of the research consisted of a design exercise in which animation techniques were used to generate a shape. For this purpose a wind simulator was used in 3DMAX. Next, Paracloud software was used to automatically generate a rib structure that allowed to produce a scale model of the shape with a laser cutter.

source SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary This study intends to propose a new use of the shape grammar: verify the influence of a certain architect’s language over another architect’s language. Some Brazilian modern architecture critics suggest the existence of an influence of Wright’s prairie houses over Artigas’ early work, but the methods used to reach to this conclusion are always empirical and not very objective. The present work aims to confirm this influence in a more rational manner, comparing Wright’s prairie houses grammar developed by Koning and Eizenberg (1981) to Artigas’ first phase grammar that will developed in this work.

summary The current work reports a methodology of analysis applied to the furniture collection of a museum which gathers items manufactured in the nineteenth century. The eclectic feature given to this collection has demanded the construction of a reasoning that points towards the formal frameworks, coming from different styles that were established through history. To answer this requirement, techniques of formal decomposition are used from the resources of photography and tridimensional modeling, thus promoting the comprehension of the geometric shape from the identification of element generation and composition rules. The speeches constructed in such analytical processes rely on conceptual maps structures as a proposal for systematizing the information about the furniture.

summary Shape grammars have been used in architecture for analysis and synthesis - in the first case, mainly for the characterization of styles and in the later for the generation of novel compositions. The present research proposes the use of shape grammars for establishing guidelines for the requalification of historical areas that have lost their original characteristics due to improper renovations. In order to develop and test the proposed method, a study was carried out in a small Brazilian town called Monte Alegre do Sul. The town was chosen because its original urban morphology, developed in the XIXth century, is still relatively well preserved, although part of the original façades have been transformed. The objective of the research is to develop a shape grammar to set guidelines for the requalification of the already renovated façades in Monte Alegre do Sul.

summary We are here, in Chicago, not to talk about what we know, but what we do not know. We are here to share ideas and to speculate about what the world might look like if it were challenged, rethought, and rebuilt. We are here to uncover, piece by piece, a sense of our own ambitions for an architecture influenced by today but motivated by tomorrow. We are all speculators and dreamers. We find places for dreaming in our work, our models, our essays, our lectures, our research, and our teaching. Through these activities we speculate on the architecture of tomorrow. Sometimes these speculations hold great promise, while at other times they do not – certainly much of what we do can be improved, refined, qualified, quantified, and genuinely benefit from being computed. This could be horrifying; it could set the scene for an engineered architecture if we do not adapt.But architecture is changing and responding to very fresh and different ways of thinking. As a movement, young architects are questioning their inheritance and establishing new values, new methods, and new forms of practice. We might best think of these young architects as the Generation X of architecture – a generation who shapes discourse through technological, social, and environmental lenses. From its smallest technical process to its highest level of thought, this conference represents the spirit of this movement.

title Dynamic Relaxation of Tensegrity Structures

source Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 553-562
summary The structural hierarchy inherent to tensegrities enables a building skin that performs on multiple levels simultaneously. While having one function in the global building mechanics, its individual components can work as self-contained systems balancing tensile and compressive forces locally within them. The behavior of elements under load is linear and thus describable analytically. When these are aggregated in a tensegrity however, the performance of the assembly as a whole is non-linear. In order to investigate further these relationships a method of dynamic relaxation will be developed. This tool allows for simulation and load analysis of a complex tensegrous network, based on the relationships between force, stiffness and dimension formulated by Young and the computational means provided by a parametric/associative modeling environment. This research investigates the possible formfinding through computational means of a double-layer tensegrity grid.

summary In experimenting with digital processes for simulating the behavior of tension-active cable nets, a method was developed for creating informed geometries by utilizing computational meshes that carry properties of structure, space, and material. A spring-based particle system provided the dynamics to simulate the flow of tension force through the geometry. Particular functions were scripted to embed logics for fabrication and analysis of spatial parameters. This formulated a lightweight, reactive design tool for which multiple cable net morphologies could be quickly generated. This paper will describe the experiments in creating the method to generate such cable net morphologies, and discuss the potential application for this computational framework to apply to other architectural systems.

source T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 37-50
summary Building design is today a major social, economic and environmental challenge. Design is also a source of innovation and an important economic driving force that requires the collaboration of professionals from various fields of expertise. But the traditional linear approach in design has shown its limits, and it often leads to non optimal design solutions and buildings with inadequate performances. This paper aims to validate a computer supported collaborative workspace that facilitates the participation, in an integrated approach, of the various members of a construction project team. The goal of the research is to be part of the evolution of work practices in design.

summary This paper details a series of preliminary explorations into the concept of kinetic tensegrity grids that can respond to stimuli by changing their shape, porosity, and transparency. The research presented explores double-layer tensegrity grids that utilize 3D “compressed” components. A case study demonstrates their applicability to the formation of sophisticated building envelopes that can actively or passively respond to changes in the environment. A computational form-finding tool is introduced to study design variations in real time. This tool is shown to expand the design spectrum by supporting increased complexity and revealing unexpected design potential. This research is significant as it outlines a practical methodology for conceiving responsive building systems. In particular, it illustrates an approach that synthesizes design concerns with engineering and fabrication goals.
