summary This paper suggests that Portuguese historical cities were based on a structured knowledge-based process from where it’s possible to retrieve not only a generative parametric urban grammar but also to construct a computational model capable to generate Portuguese planimetric proportionate and symmetrical urban grammar. The grammar is described graphically and discursively, followed by the introduction of a 2D shape grammars interpreter UrbanGENE. The 2D shape grammar interpreter will allow the user to interact with the genetic and generative principles of Portuguese historical urban design from 16th to 18th century and additionally be deployed in urban history teaching and learning.

summary This paper describes a new methodology of deriving innovative hybrid designs using shape grammars of heterogeneous designs. The method is detailed within three phases of shape grammars: analysis, synthesis and evaluation. In the analysis phase, the research suggests that original rules of each design component are grouped in subclass rule sets to facilitate rule choices. Additionally, adding new hybrid rules to original rules expands the options available to the grammar user. In the synthesis phase, the research adopts state labels and markers to drive the design generation. The former is implemented with a user guide grammar to ensure hybridity in the generated design, while the latter aims to ensure feasible designs. Lastly evaluation criteria are added to measure the degree of innovation of the hybrid designs. This paper describes the derivation of hybrid minaret designs from a corpus of heterogeneous traditional minaret designs.

summary This paper shows the first results of a prototype implementation of a generative urban design tool. This implementation will form part of a design support tool for a GIS based platform defined to formulate, generate and evaluate urban designs. These three goals, formulation, generation and evaluation are integrated by connecting three modules developed individually for each goal. In this paper we focus on the implementation of the generation module showing a prototype developed on the Integrated Development Environment (IDE) of AutoCAD Civil 3D. This implementation attempts to encode the design moves of the urban planner into design patterns supported on grammar formalisms which allow for design synthesis and design exploration in the field of urban design.

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.

summary The present paper describes the design process of a new prototypical building for the State University of Campinas, with the use of shape schemata and rules. The use of this construct or method made the design process more intelligible for the students who took part in the project and helped managing the team work. We expect that these rules will also allow the automation of the production of design alternatives and construction drawings for new buildings in the campus.

summary Nowadays, a large set of involved planning parties are heavily demanded with the definition of holistic in kind requirement specifications for urban planning sites – so called future cities. However, the resulting amountof specifications for a specific building project poses a great challenge to designers and planners especially when it comes to include this information into their design proposals for a sustainable urban development. These design performance criteria are traditionally expressed in textual and numerical planning guidelines and which are making it difficult to establish a comprehensive and holistic view onto the domain itself. Therefore we present in this paper a design guide visualization method to overcome this situation for the evaluation of design specification and urban layouts in a qualitative and quantitative manner.

summary Graphic designers always take both time and efforts when they are creating a decorative pattern with complicated curves and a great deal of motifs. Although there are many sourcebooks of decorative patterns, the satisfaction of the results couldn’t accomplish with designer’s requirements. Thus, graphic designers need a faster and easier system to create decorative patterns in classical style. There are a few effiencient methods to analysis curves and surfaces in the development of shape grammars. The purpose of this research is to develop Vine Grammar based on shape grammars. The vine grammar analyses principles hidden in the language of deisgn works to create the order, then generates design by using Bézier curves. This research also presents the development of a decorative pattern generative system called Shlishi by using FLASH Action Script 2.0. The grammar can be applied with computers and to verify rules quickly by Shlishi. The intention of this research is to make graphic designers to use these rules to create decorative patterns of plants in classic style and to produce satisfactory results for designer more efficiently or to make the results the source materials for the follow-up design works.

summary This paper describes a teaching experience conducted and carried out as part of the architectural coursework of the first year students. The workshop is the first of three planned to take place during the course of the first year studio. It aims at introducing new ways of thinking as well as introducing students to the new pattern of architectural education; It also helps communicating and-if required- unlearning accumulative conceptions that were unconsciously gained by the lack of practice, ignorance of actuality or simply by the accumulation of images and ideas in their minds over the years. A grammatical approach was chosen to develop the described methodology, based on the shape grammars system in general, and on one of its basic skills of seeing/understanding shapes & extracting elements of the visual composition in particular

summary This paper develops a formal approach to investigate the evolution of a Korean traditional pattern, Bosangwhamun. The approach employs the structure of symbolic memes embedded in the pattern as a framework of hierarchical decomposition of a pattern to describe an evolutionary development process of a given pattern with a set of rules in shape grammar as style changes. Further, the formal descriptions of the given pattern become the basis for generating its variations. With this process, the validity of the rules and their appropriateness in the representation of Bosangwhamun are examined.

summary This paper integrates traditional techniques with the parametric approach in ceramic fabrication by outlining several key parameters in both the traditional and digital ceramic fabrication process, and investigating how these parameters can accommodate parametric variation from the digital model. Findings from three experiments with different parameters suggest a promising landscape for traditional ceramic fabrication to be more compatible, not only with the parametric variation in digital modeling, but also with customized digital fabrication.

title Interweaving Grammar: Reconfiguring Vernacular Structure Through Parametric Shape Grammar
source International Journal of Architectural Computing vol. 8 - no. 2, 93-110
summary This paper re-examines the interweaving method to demonstrate how architectural computation can reinterpret the advantages of this traditional crafting techniques for its geometrical compatibility and rule generativity. Firstly, the technique analyzes and reconfigures load distribution of a traditional interwoven surface to mimic its structural principle. Secondly, from this structural reconfiguration, the study applies parametric shape grammar to define interweaving rules. The rules generate various patterns with rigid local materials that fit the size of human hand. The experiment in this study shows that interweaving grammar can generate ornamental-structural components with three different load distributions, three different segmented materials and in three different spatial dimensions (point, line and plane).

summary Cities all over the world are challenged by increasing the quality of life of urban citizens in order to ensure sustainable urban development. However, a lot of policies and planning fail in integrating environmental aspects in a way that makes them applicable for design leading to rather unsustainable developments. This paper presents an approach to integrate ecological parameters into urban design using a procedural, shape grammar driven modeling and visualization system. Design specifications and ecological goals given in the Masterplan of MASDAR City derived as an application example for the workflow. We used the concept of ecosystem services to break down the ecological process knowledge to design rules and meaningful, quantifiable spatial indicators. Our results demonstrate the application of the proposed approach covering different planning scales (district and building level). The integrated model suits as an assessment tool that can be used to test urban design alternatives on the ecological functioning as a starting point for architects.

summary Al-kazzaz et al (2010) described hybrid adaption technique to generate innovative designs from heterogeneous precedents using shape grammars. An evaluation of the degree of innovation in the hybrid designs gave feedback to grammar users before and after applying a rule. Innovation was assessed using variables derived from the internal structure of the grammar such as: the number of antecedents in the corpus having the same rule; the number of rules in a subclass rule set having the same geometry; etc. However, the validity of the innovation assessment was unclear and the use of the feedback measures was not demonstrated. Accordingly, this study aims to verify the credibility of the innovation measures and to identify the independent variables that a user can control to achieve a significant impact on each innovation measure as a dependent variable.

summary Behavioural Surfaces is a thesis project in Architecture discussed on December 2010 at the University of Florence. The project explores the surfacespace relationship in which a surface condition, generated from intensive datascapes derived from environmental data, is able to produce spatial differentiation and modulate structural and environmental preformance. Exploiting material self-organization in sea sponges as surfaces that deploy function and performance through curvature modulation and space defi nition, two different surface definition processes were explored to organize the system hierarchy and its performances at two different scales. At the macroscale, the global shape of the building is shaped on the base of isopotential surfaces while at a more detailed level the multi-performance skin system is defi ned upon the triply periodic minimal surfaces (TPMS).

summary Increasingly, digital architectural data will become available through information technology. Yet until now, there were no satisfying methods to query this data for architectural purposes. This paper introduces an information retrieval system for parcels that not only allows searching for specific attributes, but also includes properties of shape and context of the building plots. An automatically generated index stores the relevant spatial properties as normalized bitmap images on several layers. When a query is started, only this index has to be queried and not the complete database. The search process can be controlled through a graphical interface that incorporates the user’s sketches. The retrieved parcels are presented as a sorted list of vector drawings including their contained buildings. With the simplified access to these case-studies, quality and efficiency of the architectural design process could be increased.

summary The main intention of this paper is to propose a theoretical framework for an integrated design methodology which incorporates natural morhogenetic principles for the realisation of fibre composite structures. Stress, in these processes, becomes the driving force of shape modification and fibre articulation, while the material thresholds become a driver of generative evolution. The inferences and results of such an approach will be looked into using a case study of a composite monocoque shell bridge design.

We propose a geometry processing framework to approximate (rationalize) a given shape by one or multiple strips of ruled surfaces. We discuss techniques to achieve an overall smooth surface and develop a parametric model for the generation of curvature continuous surfaces composed of ruled surface strips. We illustrate the usability of the proposed process at hand of several projects, where the pipeline has been applied to compute NC data for mould production and to rationalize large parts of free-form facades.

The following paper focuses on new techniques for visualizing work processes and developments for large-scale landscape designs. The integration of these processes within a teaching environment stands at the forefront. In this context, the use of programmed tools and the immediate translation of preliminary design ideas to models using the Mini Mill in the studio allow students to investigate and test new approaches. Next steps will be explored through the use of parametric design tools.
