summary This article seeks an adequate manner to stand for a generative process in architecture. The processes of typology development in a vernacular architecture is adopted. As a proper cultural object, a type is perceived as a general principle of creation, a supra-individual mechanism. In that context, there are some issues concerning the research problem: how to adequately represent a poiesis? The related theories to support this research development are distinct. However, the theoretical framework point out shape grammar as a base for generative process representation in architecture. A generative system that operates with the same generative logic is proposed.

summary Recently we developed a prototype general shape grammar system, called Grammar Environment (Li et al. 2009). It differs from other systems in that it aims to support designers who design with shape grammars. One task of such a system is to support users in editing shapes. The guidelines that we followed in developing Grammar Environment suggested that the shape editing system should both be integrated into the system and be powerful as a drawing tool. This seemed to be contradictory. We decided to make two shape editors: one stronger on integration, the other on drawing power.

summary This paper presents a shape grammar for planned urban spaces intending an implementation for generative urban design. This implementation will form part of an urban design support tool defined to formulate, generate and evaluate urban designs. The goal is to formulate urban program descriptions according to context conditions using a description grammar and generate alternative design solutions using a shape grammar. The generation is guided by several evaluation processes performed by an evaluation module. In this paper we are focusing on the definition of the generic shape grammar using an existent urban plan as a case study. The aim is to encode the design moves of the urban designer into generic grammar rules amenable for specific instantiations through the customization of rule parameters.

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

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

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.

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.

summary In this paper, the dominant definitions of intelligence are explored in order to establish a set of working principals towards the development of higher order computational design processes in architecture. A review of intelligence as it has been understood over the last 60 years since Alan Turing (1950) first asked the question “can machines think?” shows the question of intelligence is far from clearly understood. Principals of intelligence however can be identified within the neurophysiological and artificial intelligence (AI) communities that differ significantly from the notion of intelligence as it is commonly used in architecture typically relating to the phenomena of emergence and critical point material physics. While distinct, these definitions provide a foundation for understanding intelligence specifically in computational architecture at a moment when it is necessary to develop a foundational taxonomy of systems thinking and processes. Through critiquing the principals of intelligence as it is understood in these different discipline areas, the thesis of this paper is that it is possible to frame a productive general theory of intelligent systems applicable to design processes, while simultaneously distinguishing the goals of design oriented higher order computational systems from those goals of general Artificial Intelligence research.

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’s 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.

title To Colour the Virtual World - Difficulties in Visualizing Spatial Colour Appearance in Virtual Environments
source International Journal of Architectural Computing vol. 7 - no. 2, 289-308
summary This paper discusses the problems of visualizing colour appearance in an interactive virtual environment (VE) from the viewpoint of practice based architectural research. The discussion is based upon the research information project Virtual Colour Laboratory (VCL), the aim of which is to visually present and demonstrate existing research results on spatial colour phenomena for educational purposes, in the shape of a software application. During the work on this project, various problems connected to the visualization of colour appearance have emerged which are discussed in relation to current research on spatial experience and visual appearance in VEs. The aim of the paper is to focus on the importance of colour appearance in digital modelling as well as to highlight the problems of visualizing colour appearance interactively. The term colour appearance is used here as a general concept for the perceived colour of a surface or object.

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

title 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.

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 One approach to perform the design for production of masonry with BIM tools is to explicitly represent the wall elements. However, this strategy decreases the application performance because of model complexity. Generative Modeling is a modeling paradigm aimed at defining rules and applying them for generating models. The masonry block placement is associated with a set of rules, making the use of generative modeling a viable solution to implicitly represent the blocks. This paper presents some preliminary results of our research on investigating if Generative Modeling can help in the representation of masonry modulation and for the proposal of a shape grammar for representing its basic elements.

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 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.

summary NP-hardness of parametric subshape recognition for an arbitrary number of open terms is proven. Guided by this understanding of the complexity of subshape recognition, a framework for computation-friendly parametric shape grammar interpreters is proposed, which is further detailed by a sub-framework over parametric two-dimensional rectangular shapes. As both the proof of NP-hardness and rectangular sub-framework invoke elements in graph theory, the relationship between shape and graph grammars is also explored.
