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.

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	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 ‚Äúgingerbread houses‚Äù, 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	A grammar-based system for the participatory design of urban structures [A grammar-based system for the participatory design of urban structures ]
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	We propose a three-step participatory design cycle for the early urban design phase that can be integrated into the digital design chain. Step one involves a visualization method that is implemented as an interactive card-based interview technique for the collaborative requirement specification of urban designs. In step two these specifications are a) translated into simplified GIS data and then b) implemented into a grammar-based system together with the corresponding design regulations. The final outcome is a generative and iterative urban model, which includes buildings, building blocks, transportation networks and open spaces that visually communicates spatial impacts of urban design proposals.

title	Monitoring urban design through generative design support tools: a generative grammar for Praia
source	Proceedings of 15 Congresso da APDR, Cidade da Praia, Cabo Verde.
summary	Abstract Urban planning and design has a considerable impact on the economic performance of cities and regions. It is a complex process that extends for a long period and involves many participants. The lack of integrated tools to support this process hampers the ability to maximize the response of plans to contextual conditions while using the least resources. This paper describes research that aims to develop such a tool, integrating formulation, generation, and evaluation capabilities. It is focused on the generation module which relies on the encoding of Urban Induction Patterns (UIP) using shape grammars. A grammar for the extension plan of the city of Praia is presented as one of the case studies used to support UIP definition and illustrate its application. The paper also discusses how the proposed tool can be used for developing and monitoring urban plans.

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.

title	An urban grammar for Portuguese colonial new towns in the 18th century
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 describes the morphological urban order underlying Portuguese treatises and Portuguese urban cartographic representation produced from 16th century to 18th century. The historical documentation suggests that Pythagorean-Euclidian geometry appears to be a crucial ingredient for the understanding of Portuguese urban design-thinking and urban design-making. To unveil the genesis of the morphological urban order present in the Portuguese colonial plans of the eighteenth century, a descriptive method, Shape Grammar has been adopted. Shape Grammar, as method, supports the analysis of the form-making logic and has proved to be powerful in shape analysis, description, interpretation, classification, evaluation and generation of a design language.

summary	In this paper, we suggest a generic city description model suited for purposes like semi-automatic city modeling and urban layout evaluation. The generic city model refers to basic vital functions of a (computable) city. Feature patterns are used to extend the generic city model with global and local characteristics. The Hellenistic cities serve as a platform for a first implementation to test a semi-automatic city model generation. As a result four cities are reconstructed as a first example of our ongoing work, Miletus, Knidos, Priene and Olynthus. Future work will deal with the application of the generic city model to the performance simulation of contemporary urban layouts.

summary	This paper main goal is to depict the generative principles of 16th -18th century Portuguese colonial urban design described from its Pythagorean-Euclidean geometrical genesis and correspondent logical rules and operations. These origins were found in Portuguese compendiums and treaties on practical geometry, architectural and military engineering from the sixteenth through the eighteenth century. The study attempts to show that rigorous operative geometrical discourse is inseparable from social knowledge, whereby form is the operative result of abstract mental processes and logical visual reasoning associated to ideas of growth and reproduction of order.

source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The street system is an important component of the city ontology created for a generative urban design tool and should be able to integrate the many visions or interpretations that designers or other urban design agents may have about streets. This paper describes several characteristics of the street system, with its components organized into object classes which are the shape sets of algebras used by a generation module to generate street network representations that can be assessed by a GIS platform.

summary	The paper presents a framework for parametric and generative design based on shape grammars, implemented inside a 3d animation tool. A simple description is given on how animation works, along with parity features between shape grammars and animation tools. Work covered in previous papers by the writer, namely how the designer constructs individual tools from simple animation mechanisms is here expanded in a framework of algebras that not only function in geometric dimensions but also in time.

title	A Prototype System for developing two- and Three-Dimensional Shape Grammars
doi	https://doi.org/10.52842/conf.caadria.2009.717
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 717-726
summary	A number of researchers have developed shape grammar systems, with a variety of aims. These systems all help users (to varying degrees) to run grammars, but not to develop grammars. However, we believe that developing grammars is also work and needs to be supported. A system to do this would make it easier and more convenient for people using grammars to do design work. Following the generate-test model, we design and implement a prototype system that supports the user in editing grammars, testing grammars, and switching easily between the two types of activity. We emphasize the graphic nature of the task: the user is all the time working with graphic objects, namely shapes.

summary	We propose and describe a working computer implementation for shape grammars that handles embedding relations in two dimensional shapes. The technical framework proposed explores a graph data structure to temporarily represent boundary elements of shapes and how they are assembled. With the associated algorithms, this structure enables a systematic search for parts. The employment of user defined constraints allows for an interactive search. In accordance with the continuous character of shapes, the study puts forth a practical part detection method, which extends to non-deterministic cases.

title	Multi-touch - the future of design interaction
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. 557-572.
summary	The next major revolution for design is to bring the natural user interaction into design activities. Graphical User Interfaces (GUI) brought a new approach that was more effective compared to their conventional predecessors. In recent years, Natural User Interfaces (NUI) have advanced user experiences and multi-touch and gesture technologies provide new opportunities for a variety of potential uses in design. Much attention has been paid to leverage in the design of interactive interfaces. The mouse input and desktop screen metaphors limit the information sharing for multiple users and also delayed the direct interaction for communication between each other. This paper proposes the innovative method by integrating game engine ‘Unity3D’ with multi-touch tangible interfaces. Unity3D provides a game development tool as part of its application package that has been designed to let users to focus on creating new games. However, it does not limit the usage of area to design additional game scenarios since the benefits of Unity3D is allowing users to build 3D environments with its customizable and easy to use editor, graphical pipelines to openGL (http://unity3d.com/, 2010 ). It creates Virtual Reality (VR) environments which can simulates places in the real world, as well as the virtual environments helping architects and designers to vividly represent their design concepts through 3D visualizations, and interactive media installations in a detailed multi-sensory experience. Stereoscopic displays advanced their spatial ability while solving issues to design e.g. urban spaces. The paper presents how a multi-touch tabletop can be used for these design collaboration and communication tasks. By using natural gestures, designers can now communicate and share their ideas by manipulating the same reference simultaneously using their own input simultaneously. Further studies showed that 3Dl forms are perceived and understood more readily through haptic and proprioceptive perception of tangible representations than through visual representation alone (Gillet et al, 2005). Based on the authors’ framework presented at the last CAADFutures, the benefits of integrating 3D visualization and tactile sensory can be illustrated in this platform (Chen and Wang, 2009), For instance, more than one designer can manipulate the 3D geometry objects on tabletop directly and can communicate successfully their ideas freely without having to waiting for the next person response. It made the work more effective which increases the overall efficiency. Designers can also collect the real-time data by any change they make instantly. The possibilities of Uniy3D make designing very flexible and fun, it is deeply engaging and expressive. Furthermore, the unity3D is revolutionizing the game development industry, its breakthrough development platform for creating highly interactive 3D content on the web (http://unity3d.com/ , 2010) or similar to the interface of modern multimedia devices such as the iPhone, therefore it allows the designers to work remotely in a collaborative way to integrate the design process by using the individual mobile devices while interacting design in a common platform. In design activities, people create an external representation of a domain, often of their own ideas and understanding. This platform helps learners to make their ideas concrete and explicit, and once externalized, subsequently they reflect upon their work how well it sits the real situation. The paper demonstrates how this tabletop innovatively replaces the typical desktop metaphor. In summary, the paper addresses two major issues through samples of collaborative design: firstly presenting aspects of learners’ interactions with physical objects, whereby tangible interfaces enables them constructing expressive representations passively (Marshall, 2007), while focussing on other tasks; and secondly showing how this novel design tool allows designers to actively create constructions that might not be possible with conventional media.

title	A Digital Incorporation of Ergonomics into Architectural Design
source	International Journal of Architectural Computing vol. 7 - no. 2, 235-253
summary	A project that is particularly designed for digital studio settings is described. Facilitated by multiple computer modeling and animation software, the project incorporates concepts and applications of ergonomics and kinetics as two ingredients and concept generators with problem-based learning techniques into architectural designing. Reflections about the project and its outcomes are reported and discussed. The results indicate that considerations of ergonomics, flexibility, mobility and responsiveness in dynamic structures and their interactions with users can enrich and optimize generated designs. Similarly, the application of problem-based designing approach seems to foster critical thinking of participants and improve their involvement in collaborative design processing.

title	Teaching Systems-Thinking with Algorithmic Process: Introduction to computation and programming with processing programming language
source	Digitizing Architecture: Formalization and Content [4th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2009) / ISBN 978-99901-06-77-0], Manama (Kingdom of Bahrain), 11-12 May 2009, pp. 37-46
summary	This research investigates how algorithm design and scripting as pedagogy can affect generalized design ability and understanding. Logical, systematic thinking is considered foundational in developing architectural design aptitude and is explicit when designing algorithms. The course work presented mandates the construction of process rather than product. Scripting is implemented not as a means to an end but rather a medium for exploration. More valuable than formal generator or problem-solver, these scripted designs test direct aesthetic implications. Further tested is the role of animation in de-linearizing the design process. By isolating the algorithm as topic, technique, and concept, scripting skills and the produced artifact are extendable and are translatable to other media. Algorithm design is presented as a 2-dimensional but temporal endeavor: students script an animate, interactive vector-based image. This facilitates the transition from algorithm to spatial experience while also readying students for form-based explorations. The 2-d temporal exercise is of a similar order of complexity to a 3-dimensional static condition. Pieces of the animation structure are provided as a canvas, specifically the ability of the viewer to manually control a single parametric variable that affects the visual output through a user-interface element. The following and final project of the course expands upon the technique of scripting image in the design of an experience by collaging video, images and animation.

title	Preliminary Concept Design (PCD) Tools for Laboratory Buildings, Automated Design Optimization and Assessment Embedded in Building Information Modeling (BIM) Tools.
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. 451-476.
summary	The design of laboratory buildings entails the implementation of a variety of design constraints such as building codes; design guidelines and technical requirements. The application of these requires from designers the derivation of data not explicitly available at early stages of design, at the same time there is no precise methodology to control the consistency, and accuracy of their application. Many of these constraints deal with providing secure environmental conditions for the activities inside laboratories and their repercussions both for the building occupants and population in general, these constraints mandate a strict control over the building‚Äôs Mechanical Equipment (MEP), in particular the Heating Ventilating and Air Conditioning (HVAC) system. Due to the importance of these laboratory designers are expected to assess their designs not only according spatial relationships, but also design variables such as HVAC efficiency, air pressure hierarchies, operational costs, and the possible implications of their design decisions in the biological safety of the facility. At this point in time, there are no practical methods for making these assessments, without having constant interaction with HVAC specialists. The assessment of laboratory design variables, particularly those technical in nature, such as dimensioning of ducts or energy consumption are usually performed at late stages of design. They are performed by domain experts using data manually extracted from design information, with the addition of domain specific knowledge, the evaluation is done mostly through manual calculations or building simulations. In traditional practices most expert evaluations are performed once the architectural design have been completed, the turn around of the evaluation might take hours or days depending on the methods used by the engineer, therefore reducing the possibility for design alternatives evaluation. The results of these evaluations will give clues about sizing of the HVAC equipment, and might generate the need for design reformulations, causing higher development costs and time delays. Several efforts in the development of computational tools for automated design evaluation such as wheel chair accessibility (Han, Law, Latombe, Kunz, 2002) security and circulation (Eastman, 2009), and construction codes (ww.Corenet.gov.sg) have demonstrated the capabilities of rule or parameter based building assessment; several computer applications capable of supporting HVAC engineers in system designing for late concept or design development exist, but little has been done to assess the capabilities of computer applications to support laboratory design during architectural Preliminary Concept Design(PCD) (Trcka, Hensen, 2010). Developments in CAD technologies such as Building Information Modeling (BIM) have opened doors to formal explorations in generative design using rule based or parametric modeling [7]. BIM represents buildings as a collection of objects with their own geometry, attributes, and relations. BIM also allows for the definition of objects parametrically including their relation to other model objects. BIM has enabled the development of automated rule based building evaluation (Eastman, 2009). Most of contemporary BIM applications contemplate in their default user interfaces access to design constraints and object attribute manipulations. Some even allow for the application of rules over these. Such capabilities make BIM viable platforms for automation of design data derivation and for the implementation of generative based design assessment. In this paper we analyze the possibilities provided by contemporary BIM for implementing generative based design assessment in laboratory buildings. In this schema, domain specific knowledge is embedded in to the BIM system as to make explicit design metrics that can help designers and engineers to assess the performance of design alternatives. The implementation of generative design assessments during PCD can help designers and engineers to identify design issues early in the process, reducing the number of revisions and reconfigurations in later stages of design. And generally improving design performance.

summary	The paper which is proposed here will introduce an ongoing research project aiming to research data mining as a methodology of knowledge discovery in urban feature analysis. To address the increasing multi-dimensional and relational complexity of urban environments requires a multidisciplinary approach to urban analysis. This research is an attempt to establish a link between knowledge discovery methodologies and automated urban feature analysis. Therefore, in the scope of this research we apply data mining methodologies for urban analysis. Data mining is defined as to extract important patterns and trends from raw data (Witten and Frank, 2005). When applied to discover relationships between urban attributes, data mining can constitute a methodology for the analysis of multi-dimensional relational complexity of urban environments (Gil, Montenegro, Beirao and Duarte, 2009) The theoretical motivation of the research is derived by the lack of explanatory urban knowledge which is an issue since 1970‚Äôs in the area of urban research. This situation is mostly associated with deductive methods of analysis. The analysis of urban system from the perspective of few interrelated factors, without considering the multi-dimensionality of the system in a deductive fashion was not been explanatory enough. (Jacobs, 1961, Lefebvre, 1970 Harvey, 1973) To address the multi-dimensional and relational complexity of urban environments requires the consideration of diverse spatial, social, economic, cultural, morphological, environmental, political etc. features of urban entities. The main claim is that, in urban analysis, there is a need to advance from traditional one dimensional (Marshall, 2004) description and classification of urban forms (e.g. Land-use maps, Density maps) to the consideration of the simultaneous multi-dimensionality of urban systems. For this purpose, this research proposes a methodology consisting of the application of data mining as a knowledge discovery method into a GIS based conceptual urban database built out of official real data of Beyoglu. Generally, the proposed methodology is a framework for representing and analyzing urban entities represented as objects with properties (attributes). It concerns the formulation of an urban entity‚Äôs database based on both available and non-available (constructed from available data) data, and then data mining of spatial and non-spatial attributes of the urban entities. Location or position is the primary reference basis for the data that is describing urban entities. Urban entities are; building floors, buildings, building blocks, streets, geographically defined districts and neighborhoods etc. Urban attributes are district properties of locations (such as land-use, land value, slope, view and so forth) that change from one location to another. Every basic urban entity is unique in terms of its attributes. All the available qualitative and quantitative attributes that is relavant (in the mind of the analyst) and appropriate for encoding, can be coded inside the computer representation of the basic urban entity. Our methodology is applied by using the real and official, the most complex, complete and up-to-dataset of Beyoglu (a historical neighborhood of Istanbul) that is provided by the Istanbul Metropolitan Municipality (IBB). Basically, in our research, data mining in the context of urban data is introduced as a computer based, data-driven, context-specific approach for supporting analysis of urban systems without relying on any existing theories. Data mining in the context of urban data; ‚Ä¢ Can help in the design process by providing site-specific insight through deeper understanding of urban data. ‚Ä¢ Can produce results that can assist architects and urban planners at design, policy and strategy levels. ‚Ä¢ Can constitute a robust scientific base for rule definition in urban simulation applications such as urban growth prediction systems, land-use simulation models etc. In the paper, firstly we will present the framework of our research with an emphasis on its theoretical background. Afterwards we will introduce our methodology in detail and finally we will present some of important results of data mining analysis processed in Rapid Miner open-source software. Specifically, our research define a general framework for knowledge discovery in urban feature analysis and enable the usage of GIS and data mining as complementary applications in urban feature analysis.

summary	Departing from a case analysis extracted from the context of didactic practices directed to the initial stages of Architectural Project learning, the necessity of limiting a conceptual net which expresses an updated geometric knowledge is assumed in order to sustain the characterization activity of the architectonic shape. For the case which was analyzed one identifies, through the light of traditional project approaches and from those originated from practices of digital graphic representations and shape grammars, a set of concepts and procedures that allows to explicit a knowledge structure considered able to support and strengthen the activity in question. Such structure is represented through conceptual maps that allow observing, visually, the amplification of concepts which in this study are identified with the geometric vocabulary and repertoire. It faces the necessity of recognizing a terminology to explicit such elements and, thus, experimenting the usage of established taxonomy in the context of architecture. In the present study, a metacognitive approach is added, associating practices of Geometric Modeling and Shape Grammars to the mechanisms of deductive and inductive metacognition, respectively. This perspective of analysis is proposed to contribute for the disciplinary integration: project and representation centered on the construction of a geometric vocabulary and repertoire to architecture.
