summary “Ce n’est point le navire qui naît de la forge des clous et du sciage des planches. C’est la forge des clous et du sciage des planches qui naissent de la pente vers la mer et croissance du navire” (Saint-Exupéry, 1948). The paper describes and analyses a course held at Stuttgart University, Germany dealing with the application of parameters in an architectural design process and the transformation of this process into a relational digital model. The course is introduced with special emphasis on its tasks, aims and the implicit didactic concept. It is also investigated if and how a design approach resulting from the identification and determination of parameters can lead to a creation of a unique shape. Finally the impact of the practical exercises for the final design is evaluated. The course’s structure is enhanced by the “Vorklasse” from Bauhaus and the conviction that using software is taught most effectively by working on an own specific project. At the very beginning the students get the chance to gain experiences with parameters through preliminary practical exercises, like folding and modelling and analysing. Then the use of the software is taught in several compact sessions in parallel to the design process. The impact of the early practical exercises on the subsequent design process is remarkable. Special attention is therefore given to this aspect. The aim of the lessons is to produce a proposal for the design task. The proposal is then to be presented as a parametric model representing either the global shape or a constructive detail.

title Soft Façade: Steps into the Definition of a Responsive ETFE Façade for High-rise Buildings
doi https://doi.org/10.52842/conf.ecaade.2007.567

summary Façade systems are to a great extent responsible for both the energy-performance and overall aesthetic qualities of a building. The study presented in this paper explores the tectonic integration of a distributed computer network and the façade of a high-rise tower through the use of ETFE cushions, exploiting the soft nature of this material to embed a sensor network to provide touch-responsive changes of opacity in the façade, potentially improving the energy-efficiency of a building, and promoting a novel kind of dialogue between a space and its inhabitants. We propose that the inclusion of computer networks and displays in the built environment necessarily leads to new design philosophies that solve tectonically the dialogue between traditional materials and technological devices, and we put forward the first results of a research into a novel implementation of electrochromic ‘smart’ cushions that allows for changing opacities of the façade elements of a building in response to human touch.

summary Residents’ active participation is necessary for a feasible community design from the planning stage to maintenance and management. it is necessary to show information related to a plan efficiently to facilitate understanding, and to consider a plan in a limited time. The purpose of this study is to develop a Community Space Design system (CSDS) that can use GIS data and Real-time simulation, in order to support comprehension of 3D area information during continuous development. Using CSDS, participants were able to treat various GIS data fixed, and a subject called the division and the disaster prevention of a community, which the object ground is holding can be understood visually on the same 3D space as real space. Because their solution was found, the design was accepted quickly.

summary To depict characteristics of historical buildings, digital archives must display visual information about structures and their construction. This study defines the components used for three-dimensional (3D) models of framework construction. Framework construction has heretofore portrayed structures through animation using VHS or Hi-Vision video. This paper describes a method to facilitate exhibition through interactive simulation using animation and real-time images. Furthermore, a Tablet MR can be used as an effective simulation tool for studying historical buildings in on-site models. For education about historical wooden-framework architecture, increased interactive potential according to users’ needs will be increasingly necessary.

title Visual-Physical Grammars
source SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary This paper introduces new visual-physical design grammars for the design and manufacture of building assembly systems that provide visually rich, culturally resonant design variations for housing. The building systems are intended to be tailored for particular cultures and communities by incorporating vernacular, decorative design into the assembly design. Two complementary areas of computational design research are brought together in this work: shape grammars and digital fabrication. The visual or graphic aspects of the research are explored through shape grammars. The physical design and manufacturing aspects are explored through advanced digital design and fabrication technologies and, in particular, build on recent work on mono-material assemblies with interlocking components that can be fabricated with CNC machines and assembled easily by hand on-site (Sass, 2007). This paper describes the initial, proof-of-concept stage of this work: the development of an automated, visual-physical grammar for an assembly system based on a vernacular language of Greek meander designs. A shape grammar for the two-dimensional Greek meander language (Knight, 1986) was translated into a three-dimensional assembly system. The components of the system are uniquely designed, concrete “meander bricks” (Figure 1). The components have integrated alignment features so that they can be easily fitted and locked together manually without binding materials. Components interlock horizontally to form courses, and courses interlock vertically in different ways to produce a visual variety of meander walls. The assembly components were prototyped at desktop scale with a layered manufacturing machine to test their appearance after assembly and their potential for design variations (Figure 2). Components were then evaluated as full-scale concrete objects for satisfaction of physical constraints related to concrete forming and component strength. The automated grammar (computer program) for this system generates assembly design variations with complete CAD/CAM data for fabrication of components formed from layered, CNC cut molds. Using the grammar, a full-scale mockup of a corner wall section was constructed to assess the structural, material, and aesthetic feasibility of the system, as well as ease of assembly. The results of this study demonstrate clearly the potentials for embedding visual properties in structural systems. They provide the foundations for further work on assembly systems for complete houses and other small-scale structures, and grammars to generate them. In the long-term, this research will lead to new solutions for economical, easily manufactured housing which is especially critical in developing countries and for post-disaster environments. These new housing solutions will not only provide shelter but will also support important cultural values through the integration of familiar visual design features. The use of inexpensive, portable digital design and fabrication technologies will allow local communities to be active, cooperative participants in the design and construction of their homes. Beyond the specific context of housing, visual-physical grammars have the potential to positively impact design and manufacture of designed artifacts at many scales, and in many domains, particularly for artifacts where visual aesthetics need to be considered jointly with physical or material requirements and design customization or variation is important.

summary This paper proposes a computational method for visualizing animated human reactions to physical conditions that are described in a synthetic architectural model. Its goal is to add a sense of place to the geometry, and augment the representation of its spatial quality for designers and audience. Spatial qualities in architectural design cannot be fully evaluated solely by observing geometrical constructs without reference to inhabitants placed inside. However, imagining what happens to those inhabitants and appreciating their movement is difficult even for trained architects. The proposed method introduces a walking scale figure in a geometric model. Through agent-based computation, it moves inside the model and displays various behaviors in reaction to spatial characteristics such as transparent surface, opaque surface, perforation and furniture. This method lays a foundation for developing a new kind of software that overcomes the shortcomings of current design tools.

title Rapid Craft: Material Experiments towards an Integrated Sensing Skin System

source Expanding Bodies: Art • Cities• Environment [Proceedings of the 27th Annual Conference of the Association for Computer Aided Design in Architecture / ISBN 978-0-9780978-6-8] Halifax (Nova Scotia) 1-7 October 2007, 182-191
summary The distinction between matter (mechanics) and information (electronics) in the context of responsive building skins has promoted unique design protocols for integrating sensor technologies into material components. Such a distinction results in applications of remote sensing after the process of material fabrication. Sensors are commonly perceived as electronic patches which initiate mechanical output with response to electrical input. This work seeks to establish a novel approach to the application of electronics in building skins, which prioritizes material selection, behavior, and fabrication technology in relation to the required task, over postproduction sensor integration. The term “Rapid Craft” is proposed to describe such design protocols which couple material behavior and fabrication in the design of responsive skins. Rapid Craft is a designation for the incorporation of craft materialization knowledge within the framework of CNC processes of fabrication. A light-sensing inflatable skin system is developed as a working prototype, which demonstrates such an approach.

summary The distinction between material behavior (mechanics) and material response (electronics) in the framework of responsive building skins has promoted unique design protocols for integrating sensor technologies into material components. Such a distinction results in the implementation of remote sensing devices post the process of material fabrication. Sensors are commonly perceived as electronic add-on patches which initiate mechanical output with response to electrical input. This work seeks to establish a novel approach to the integration of electronics in building skins which prioritizes material selection, behavior and fabrication given a required task, over post-production sensor application. The term “FAB Finding” is proposed to describe an instrumental methodology facilitating the coupling of CNC fabrication processes with material organization and behavior. It offers a design mentality which emphasizes the nature and the effects brought about by the use of specific fabrication processes which are by definition inherent in the design product and its behavior. A light-sensing inflatable skin system is developed as a working prototype demonstrating such an approach.

title Get Real Towards Performance-Driven Computational Geometry
source International Journal of Architectural Computing vol. 5 - no. 4, pp. 663-684
summary In historic design conventions geometry has traditionally promoted descriptive manifestations of form. Beyond the realm of geometry, the concept of performance which may inform such manifestations also carries important potential for design generation. This work explores the relation between geometry and performance from a computational-geometry perspective. It does so by revisiting certain analytical tools offered in most of today's 3-D modelers which support the evaluation of any generated surface geometry specifically curvature and draft angle analysis. It is demonstrated that these tools can be reconstructed with added functionality assigning 3-D geometrical features informed by structural and environmental performance respectively. In the examples illustrated surface thickness (as a function of structural performance) is assigned to curvature values, and transparency (as a function of light performance) is assigned to light analysis values. In a broader scope this work promotes a methodology of performance-informed form generation by means of computational geometry. Vector and tensor math was exploited to reconstruct existing analytical tools adapted to function as design generators.

Resinimpregnation patterns are applied to 2D pre-stretched form-active tension systems to induce 3D curvature upon release. This method enables form-finding based on material properties, organization and behaviour. A digital tool developed in the Processing environment demonstrates the simulation of material behaviour and its prediction under specific environmental conditions. Finally, conclusions are drawn from the physical and digital explorations which redefine generative material-based design computation, supporting a synergetic approach to design integrating form, material and environment.

We explored a process in making tabletop models with digital fabrication machines and thin plywood sheets. Each was built from combination of predetermined wood joining techniques and structures. These models are believed work as simulation of full scale constructs that inform CAD modeling. Results illustrate the limited potential of parametric modeling and inform fabrication and assembly of design variations.

summary This paper will present a prototype open source CAD system developed recently by a join effort among Harvard, CMU, and MIT. The system is composed of an expandable user interface, a data structure that supports 2D and 3D objects, image processing capabilities, animation, network communication (TCP/IP), serial interface, and file processing modules that can be expanded. The idea was to develop seed modules that can interact with one another in order to be modified, expanded, or new ones added. The language used is Processing and the setup is made to be implemented in an open source format (i.e. GNU and Google Code). The system is an open source universal architectural CAD system that will hopefully serve as the software standard for education and practice.

title The Role of GIS in Documenting Bahrain’s Historic Cities

summary Geographic information systems have long been established as useful tools for urban planning. The aim of this study is to put forward applications of GIS (Geographic Information Systems) to urban conservation in cities with architectural heritage. The study presents a specific database design to be integrated within a GIS, and the methodology of gathering data for such a database. This study concerns Bahrain’s architectural heritage, which includes many significant historic buildings as well as an overall traditional character of Bahrain’s old towns. This heritage is endangered due to extensive new urban development and the general neglect over the past decades. The study also describes an experimental database that is implemented for documenting the urban character of the old towns of Manama and Muharraq. This database was tested during a partial visual survey of Manama. It is hoped that this database will be the nucleus of a long-term process of urban conservation in the Kingdom of Bahrain. The work described here is part of a larger study conducted by the UNDP (United Nations Development Program) and the municipal government in Bahrain. A group of international experts in urban planning, urban design, and historic preservation also presented their own specific recommendations. The author of this paper was responsible for designing the GIS that helps in documenting the historic cities of Bahrain. This report proposes the development of a geographic information system for urban conservation planning. The system supports planning specialists and decision makers in their areas of work, such as the creation of urban conservation zones and redevelopment strategies. The system documents existing structures and their present conditions in order to assist in decisions regarding their preservation, restoration, and possible reuse. Such a system will also help the municipalities in regular heritage management tasks.

title Materializing Design: contemporary issues in the use of cad/cam technology in the architectural design and fabrication process
source Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 317-326
summary While the ability to produce and quantify design and fabrication information has been greatly enhanced by advances in CAD/CAM technology over the last several decades, a practical link between what can be modelled virtually and what can be built physically has yet to be realized. The process of parsing complex design information and translating it into a format that can be utilized by those responsible for its fabrication is a many-stepped process, in some cases made increasingly difficult by the same technology intended to simplify the process. The use of CAD/CAM technology in the architectural design process requires ongoing consideration as its use becomes increasingly pervasive in the design process. Within the context of contemporary architectural practice and discourse, what is the degree of fidelity between design information and fabrication information? How are advances in accessibility to, and the capability of CAD/CAM technologies affecting the role of the architect in the overall building process? Does CAD/CAM offer unique and undiscovered possibilities to re-associate the designer with the builder, or simply a process of more efficiently automating the design and construction process? Our work builds upon issues of the fundamental differences that CAD/CAM technologies introduce to design practices; issues that were raised at the very outset of CAD/CAM’s introduction to architectural design. Employing parametric design software, we design and construct a speculative façade system for a high-rise tower which is then fabricated at a reduced-scale with various two-axis CAM technology. We use relational and constraint-based logics in order to create models of parametric assemblies of discrete components which are translated into machine-ready formats, fabricated and re-assembled, in a process modelled on that typically followed in the construction of a real building project.

The prototypes themselves are user interactive objects employing Nickel Titanium Shape Memory Alloy.

summary This paper introduces a practical approach to constructing a hybrid 3D metrical–topological model of a university campus or other extended urban region from labeled 2D floor plan geometry. An exhaustive classification of adjacency types is provided for a typical infrastructure, including roads, walkways, green-space, and detailed indoor spaces. We extend traditional lineal techniques to 2D open spaces, incorporating changes in elevation. We demonstrate our technique on a dataset of approximately 160 buildings, 800 floors, and 44,000 spaces spanning indoor and outdoor areas. Finally, we describe MITquest, a web application that generates efficient walking routes.
