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	Shape grammar transformations have been used for developing new design styles by the systematic modification of grammars that encode existing styles. We make use of a style description scheme to aid grammar transformations for goal driven style change. A rule base was authored for the design of Greek temple facades, and was augmented with a style description scheme. These were tested at a student workshop wherein students were asked to develop grammars based on given style briefs. Results gained from the workshop confirmed that most students were able to assemble and transform grammars successfully. The method was found to be useful for teaching style and grammars to students and novice designers.

summary	Applications of information technology (IT) in the architectural profession have greatly increased in the past decades, ranging nowadays from concept design to automated construction. There are countless applications in the architecture practice that go well beyond representation, such as BIM software, generative design systems, and rapid prototyping and fabrication. For this reason, IT has been a frequent graduate research topic. In the present research academic graduate theses that dealt with IT in architecture since 1999 were surveyed and categorized, with the purpose of comparing the topics, applications and methods that are studied in Brazil and abroad. We hope that the differences found will help Brazilian architecture schools to update their IT curriculum, overcoming old prejudices against the use of computers in the creative phases of design.

title	A Theoretical Framework for the Implementation of Building User’s Lifestyle in nD CAD System
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. 595-606
summary	People’s lifestyle, traditions and culture affect the way they live, interact with the built environment and erect buildings. Lifestyle influences the physical characteristics of the space such as: organization of spaces, distances between spaces and location of spaces. Taking lifestyle aspects into account by architects would provide comfortable environment that is tailored to people needs and aspirations. On the other hand, rapid developments in computer modeling of buildings since 1960, led to the invention of 3D CAD systems that are capable of modeling the physical volume, shape and form of buildings and helping project team members to virtually visualize buildings. 4D CAD systems went beyond the mere 3D modeling of the physical building as they link the 3D virtual building model with other building’s information such as construction process, cost estimation etc. The nD CAD research that emerged in the late 1990s proposed endless dimensions of CAD modeling that would include the building regulations’ requirements, basic user needs and client requirements. This paper argues that it would not be enough to model the client requirements and some of user/ occupant’s physical and environmental aspects as it does not reflect the real utilization of the building by building’s user and the way that he/ she likes to live. This research aims to define the lifestyle characteristics of the architectural space and its boundaries. It suggests that various aspects of the user’s lifestyle such as degree of privacy, flexibility and adaptability required for each space, organization of internal spaces and style of spaces should be implemented in the future nD CAD models. Such implementation would enable designers to consider real life scenarios, model the real needs of people and provide the adequate end product for them.

title	Procedural Design of Urban Open Spaces

summary	This paper presents a novel approach for the automatic creation of vegetation scenarios in real or virtual 3D cities in order to simplify the complex design process and time consuming modeling tasks in urban landscape planning. We introduce shape grammars as a practical tool for the rule-based generation of urban open spaces. The automatically generated designs can be used for pre-visualization, master planning, guided design variation and digital content creation in general (e.g. for the entertainment industry). In a first step, we extend the CGA shape grammar by Müller et al. (2006) with urban planning operations. In a second step, we employ the possibilities of shape grammars to encode design patterns (Alexander et al., 1977). Therefore, we propose several examples of design patterns allowing for an intuitive high-level placement of objects common in urban open spaces (e.g. plants). Furthermore, arbitrary interactions between distinct instances of the vegetation and the urban environment can be encoded. With the resulting system, the designer can efficiently vegetate landscape and city parks, alleys, gardens, patios and even single buildings by applying the corresponding shape grammar rules. Our results demonstrate the procedural design process on two practical example scenarios, each one covering a different scale and different contexts of planning. The first example illustrates a derivation of the Garden of Versailles and the second example describes the usage of high-level rule sets to generate a suburbia model.

summary	Urban Design processes need to adopt flexible and adaptive procedures to respond to the evolving demands of the contemporary city. To support such dynamic processes, a specific design methodology and a supporting tool are needed. This design methodology considers the development of a design system rather than a single design solution. It is based on patterns and shape grammars. The idea is to link the descriptions of each pattern to specific shape rules inducing the generation of formal solutions that satisfy the pattern. The methodology explores, from the urban designer point of view, the capacity of a shape grammar to codify and generate urban form (Duarte et al, 2007). This paper defines the ontology of urban entities to build on a GIS platform the topology describing the various components of the city structure. By choosing different sets of patterns the designer defines his vision for a specific context. The patterns are explicated into shape rules that encode the designer’s interpretation of the pattern, and operate on this ontology of urban entities generating solutions that satisfy the pattern’s concept. Some examples of the topological relations are shown.

summary	This paper presents an experience of collective digital fabrication and parametric modeling of furniture made with recycled plastic waste, inspired by natural elements of the Brazilian northeast. In addition to conventional joinery techniques, we highlight the technologies of rapid prototyping (PR) and digital fabrication (FD) (Volpato, 2007, Pupo, 2008; Pupo, 2009); as tools that promote a paradigm shift, both in the design process and in production and materialization (Kolarevic, 2005), allowing recycled plastic to have new applications. We started with a brief review of digital fabrication processes in Brazil, emphasizing collaboration in design and execution. Then, we contain the recycling of plastic and the need for actions for its best destination. Finally, we present a sustainable and collaborative design experience: the modeling and digital fabrication of furniture, entirely produced from recycled plastic, called “Banco Cabaça”.

title	Tagging Your Body Virtually : Represent a place making process with social network
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. 543-558
summary	This research focuses on the virtual environment of place making. In this paper we would like to emphasize that the place making should be stressed collective views in order to obtain the design application of possibilities. However, in past researches there has been no study that tried to collect the collective views by digital ways. Accordingly, this paper proposes a response thought the Spatial Intention. It could be used to represent the human of body experience. The "moving" and "standing" are appropriate to two main considerations. Both of these could be connected to the action of "focus" and "choice." these leads to a sequential relationship of place production. The positive significance of the spatial intention lies in the convertibility of physical experience could be implied with a specific understanding. It also could be used to mold the place of knowledge structure. Thereby in order to verify the reliability of the above, we made a social network of virtual environment and used the rapid prototyping method to develop a prototype system. Implementing on the Chinese garden of the actual case, we found that the tag could concentrate as an entire sense in somewhere of place. These tags also could be shared remotely through the social network. Different tags in the sharing mechanism could collage out a place of collective views. This perspective would be used to assist designers to understand the sense of place. It also would be applied to find out the environmental design of possibilities in the future studies.

doi	https://doi.org/10.52842/conf.caadria.2007.x.a9l
summary	Shape grammar has been shown to be a frame of work applicable to design issues in various fields. Almost all published grammars work only on the bottom level of shape replacement, however in practice, when using grammars to generate designs, the designer may work on different levels of abstractions, concerning about the hierarchy of the design as well. This suggests that, to make the generating process more coherent, the grammar itself need be able to work on different levels, too. This paper introduces the research work that aims at proposing a set of guidelines for writing shape grammar with which the designer could write structured shape grammars that will be easily automated for generating designs.

doi	https://doi.org/10.52842/conf.acadia.2008.458
summary	Prototype manufacturing as an educational tool has been very successful at the college level in architecture and engineering design. This paper discusses an innovative inquiry-based learning approach rather than the problem-based learning models commonly utilized by other similar programs. For example, several research-funded technology projects (e.g., Cappelleri et al. 2007) look at involving students in problem-based learning exercises (e.g., building robots); however, these exercises (while providing valuable experiences) have predetermined outcomes ingrained by the teachers, the project structure, and the components used to construct the devices. Therefore, inquisitive and creative problem solving is limited to the “kit-of-parts” in their approach to solving the problem. The inquiry-based CADCAM pedagogy model is more concerned with the process of solving a problem through the vehicle of prototyping than with the specificity of the design project itself. This approach has great potential. First, the need to solve the problem drives learning on multiple levels, integrating interdisciplinary ideas into the problem and solution. Second, the problem interlocks disciplines through inquiry knowledge building in team exercises. Finally, it encourages diversity and flexibility by allowing students to look at problems from multiples perspectives and points of view.

summary	Presently, only a small percentage of people in the world typically hire an architect to design and build a home which is tailored to their preference. Besides the architect’s fee, clients also need to wait an interminable time for design and construction. Factory-made prefabricated housing systems tried to solve this problem previously. However, most pioneers failed to address the issues of variability and individual needs (Kieran & Timberlake, 2004). Plants closed because they produced more than the market demand, and prefabricated housing provided less flexibility than the traditional stick-built housing. The advanced digital technology makes it possible to communicate design ideas and concepts to others more effectively. The project delivery process leads itself to customization, embodying principles of lean production (Pine, 1993), flexible computer-integrated design interaction with clients, and reduced cycle times; all effecting rapid response between consumers and producers.

source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
doi	https://doi.org/10.52842/conf.caadria.2007.x.k9q
summary	There is a continuous and urgent need for disaster relief in Thailand and countries suffering from floods and tsunami impact. Based on this issue, design and planning software for temporary housing project has been developed, as well as the process and guideline for implementation. This paper describes a unique coupling of interactive 3D virtual environment with parametric designing in order to manage disaster relief project more efficiently. Architects and planners can use the functionality of software on both design simulation and project evaluation aspects. We need to provide correct information to help people making decision when they are in disaster. So the disaster relief decision support system must offer proper information of crisis management focused on people, place, and process. One of the main features of software is the relationship modeling of essential factors such as number of people, houses, budget, time, and space. This automatic temporary houses generation and space planning is simulated for land use and layout plan design with cost estimation analysis. The system components were proposed to a new disaster relief system in alternative approach. Using community-based development will not cost budget but required people participation. Our software’s space coordination will start and centered from available space in school or temple with sufficient infrastructure. After essential factors are inputted, appropriated number of temporary houses, public facilities, and management guideline will be generated to support further planning decision. Our core system was developed on Java and Swing Technology, empowered by real-time 3D rendering CAD engine. In addition, “Virtools” as our Authoring Tools was applied to improve design interaction and explore rapid software prototyping. At the end, we discuss the comparison between real situations in Thailand and appropriate design standardization, which should be reconsidered how to manage crisis with the limitation of time and budget from government.

title	Sketch-based Methods for Researching Building Layouts through the Semantic Fingerprint of Architecture
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. 85-102.
summary	The paper focuses on the early stages of the design process where the architect needs assistance in finding reference projects and describes different aspects of a concept for retrieving previous design solutions with similar layout characteristics. Such references are typically used to see how others have solved a similar architectural problem or simply for inspiration. Current electronic search methods use textual information rather than graphical information. The configuration of space and the relations between rooms are hard to represent using keywords, in fact transforming these spatial configurations into verbally expressed typologies tends to result in unclear and often imprecise descriptions of architecture. Nowadays, modern IT-technologies lead to fundamental changes during the process of designing buildings. Digital representations of architecture require suitable approaches to the storage, indexing and management of information as well as adequate retrieval methods. Traditionally planning information is represented in the form of floor plans, elevations, sections and textual descriptions. State of the art digital representations include renderings, computer aided design (CAD) and semantic information like Building Information Modelling (BIM) including 2D and 3D file formats such as Industry Foundation Classes (IFC) (IAI, 2010). In the paper, we examine the development of IT-technologies in the area of case-based reasoning (Richter et al., 2007) to provide a sketch-based submission and retrieval system for publishing and researching building layouts including their manipulation and subsequent use. The user interface focuses on specifying space and their relations by drawing them. This query style supports the spatial thinking approach that architects use, who often have a visual representation in mind without being able to provide an accurate description of the spatial configuration. The semantic fingerprint proposed by (Langenhan, 2008) is a description and query language for creating an index of floor plans to store meta-data about architecture, which can be used as signature for retrieving reference projects. The functional spaces, such as living room or kitchen and the relation among on another, are used to create a fingerprint. Furthermore, we propose a visual sketch-based interface (Weber et al., 2010) based on the Touch&Write paradigm (Liwicki et al., 2010) for the submission and the retrieval phase. During the submission process the architect is sketching the space-boundaries, space relations and functional coherence's. Using state of the art document analysis techniques, the architects are supported offering an automatic detection of room boundaries and their physical relations. During the retrieval the application will interpret the sketches of the architect and find reference projects based on a similarity based search utilizing the semantic fingerprint. By recommending reference projects, architects will be able to reuse collective experience which match the current requirements. The way of performing a search using a sketch as a query is a new way of thinking and working. The retrieval of 3D models based on a sketched shape are already realized in several domains. We already propose a step further, using the semantics of a spatial configuration. Observing the design process of buildings reveals that the initial design phase serves as the foundation for the quality of the later outcome. The sketch-based approach to access valuable information using the semantic fingerprint enables the user to digitally capture knowledge about architecture, to recover and reuse it in common-sense. Furthermore, automatically analysed fingerprints can put forward both commonly used as well as best practice projects. It will be possible to rate architecture according to the fingerprint of a building.

title	The Creation of Urban Form: A Normative Approach to Modelling
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
doi	https://doi.org/10.52842/conf.caadria.2007.x.t8k
summary	The aim of this research project is to develop a methodological process that allows the designer to assemble and create various scenarios representing an urban environment through the utilization of economical computer based methods. During the last decade different techniques have been developed to address the needs of visualisation of urban areas many being based on photographic and photogrammetric systems. The demand for 3-D urban models continues to grow and although new technologies have undoubtedly reduced the time needed for the construction of a 3D model, there are still some remaining problems related to data quality and the level of the dimensional accuracy. On the basis that these problems are primarily related to software and hardware constraints and in conjunction with the fact that the richness and complexity of an urban space is difficult to represent in a 3D context, there is a growing interest in the modelling of the urban fabric which is not dependant on heavily capitalised technology for its data. The core principle of the current research project is summarised in the process of deploying a mechanism, which will allow the visualisation of urban form without loosing its quality and architectural characterisation. This technique suggests that a selection of various building types can be collected and described by their architectural elements, textures, scale and dimensions. From each group of buildings a library of fragmented architectural components can be then derived. The accomplishment of this methodology is the formulation of a 'grammar' comprised of a characteristic ‘syntax’ and its associated ‘vocabulary’. Therefore the expected outcome of this research is an approach that would allow the designer to create easily and quickly not only any desired building but additionally any imaginary cityscape.

summary	Special effects technology can facilitate dynamic sketching in the early stage of a design project without needing time-consuming effort. This form of sketching was tested in a design studio taught by the author. The study of dynamic materials and oceanfront site conditions set the stage at the beginning of a design process for a more comprehensive analysis later on. On the one hand, the risk of using special effects tools is that the visual look can seem convincing, but the apparent result is based upon an overly simplified set of assumptions. On the other hand, the use of such technology can be very stimulating to the design imagination without requiring complex analysis that may bog down the free flow of ideas. Once a greater commitment is made to a particular design proposal, more complete physical analysis and modeling can be undertaken to help avoid the risk of false first impressions. In the studio, cloth simulation was used to develop the design of tension membrane structures (tents) that retracted and unfurled in a series of complex movements. Fluid dynamics effects were used in the design and development of related boat dock facilities. A wind-tunnel simulation tool was used to explore the performance of the tension-membrane fabrics under varied wind loads. The visualization techniques were complemented by ¼ to ½ scale assembled components created by rapid prototyping. The use of an actual wind-tunnel further tested the prototypes in some cases. On the whole, quickly implemented special effects were the starting point for reacting to and developing some initial design concepts and served as the basis for more complete physical modeling of prototypes later on. Using animation as a design method is well established in other work (Hirschberg 06). Animation is also a helpful way to work out the step by step assembly of complex architectural form (Mark 95). The special effects tools permit a larger range of initial design alternatives to be initially considered that are subsequently narrowed down by physically based prototypes that are more predictive of real world performance.

title	Teaching 3D Generative Virtual Architecture with VIPA CONSTRICTOR

summary	CONSTRICTOR is a novel teaching and learning tool to introduce students of architecture to the fundamentals of computational design. It was developed within an EC funded e-learning project, VIPA (Virtual campus for virtual space design Provided for European Architects). In this paper, we describe the general structure and technology of CONSTRICTOR and its application within the course “Synthetic Constructions II”) that aims at familiarizing students with concepts like cellular automata, swarms, shape grammars, path finding etc. CONSTRICTOR allows students to observe simulations, navigate through them and change the parameters that define and control them, thereby developing an understanding for the rules that govern their virtual environments. They can also change the geometry used in the simulations and work with and export their results. Students can modify the simulations at code level, combine them or write entirely new simulations. Finally some of the student work performed during and after the course is described, and an outlook for future work and further developments around the VIPA courses and the constrictor software will be given.

title	The New Architecture of Phase Change: Speculations on Ice Rapid Prototyping

summary	The paper presents speculative avenues for constructing 3-D ice models at various scales using traditional fabricating methods and modern CNC and rapid-prototyping techniques. Canada has a long history of using ice and snow for the construction of houses (igloo), ice palaces, and ice roads, in some cases dating back thousands of years. These techniques will be reviewed and evaluated for their suitability in modern uses. Computer-driven ice imaging and production methods present many opportunities and challenges. On the software side, we will speculate on how to use parametric software for form-finding; on the hardware side, we will reflect on how to translate these models into task planning for ice-building machines. Initially, these machines will be off-the-shelf robots and rapid prototyping machines, but we envision using specially constructed “cold irons,” “re-icing” robots, and automatic “ice bricklaying” machines. Vapour deposition on a substrate is envisioned as well. An overview of the design and adaptation of water delivery systems, through drip or spray nozzles, as well as methods of cooling water through natural or artificial means will be given. The role of additives (for colour and / or strength) will be outlined.
