title	Open Ontology: A Self-Organizing Tool for Knowledge Acquisition in a Case Library
doi	https://doi.org/10.52842/conf.caadria.2008.328

summary	This paper is aimed to establish a sufficiently formalized, expandable metadata authoring tool of a case library based on ontology methodologies of AI. This tool cannot only self-organize facts of cases’ features, but can also guide users to arrange those facts into a formalized structure to facilitate design reasoning. Then knowledge experts, such as design instructors or project managers, can apply this tool to author and organize metadata of cases’ features in order to build knowledge templates for special situations. Beginners, such as students or assistants, can apply those templates to indicate and analyze facts of collected cases’ features and acquire essential knowledge in solving problems. Finally, through easily recognized semantic relations of metadata, facts of cases’ features can be self-organized, and the system can apply data mining techniques to detect and discover hidden knowledge patterns among facts of cases’ features.

title	A study about facades from historical brazilian town using shape grammar
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
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. The use of shape grammars proposed here starts with the definition of a set of rules for characterizing the original style of an area. Based on these rules, the main characteristics of the area are confirmed, such as siting, proportions between walls and openings in the façades, overall dimensions constraints, and so on. Next, the rules of the grammar are transformed, to allow the use of contemporary building materials, as well as the incorporation of contemporary living styles in the new design. Rules must take into account two cases: original buildings that have been inadequately transformed, and buildings that have been completely torn down and will replace been completely replaced by new constructions. Both cases need to be harmonious with the remaining original buildings, however without simply copying the existing style. In both cases, rules have been used to establish the guidelines for the renovations, which resulted in modern urban environments that resemble the original historical sites in terms of spatial relations and proportions. They also create an appropriate environment for the observations of the preserved original buildings, which would otherwise look like aliens in a completely transformed neighborhood. The latter case is very common in most Brazilian cities, especially in the case of São Paulo, where houses from the late 1800´s and early 1900´s are flanked by high rise apartment buildings. In order to develop and test the proposed method, a study will be 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 re-adaptation of the already renovated façades and reconstruction of other ones in Monte Alegre do Sul.

title	Road hierarchy and speed limits in Brasília/Brazil
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	This paper aims at exploring the theory of the Social Logic of Space or Space Syntax as a strategy to define parameters of road hierarchy and, if this use is found possible, to establish maximum speeds allowed in the transportation system of Brasília, the capital city of Brazil. Space Syntax – a theory developed by Hillier and Hanson (1984) – incorporates the space topological relationships, considering the city shape and its influence in the distribution of movements within the space. The theory’s axiality method – used in this study – analyses the accessibility to the street network relationships, by means of the system’s integration, one of its explicative variables in terms of copresence, or potential co-existence between the through-passing movements of people and vehicles (Hillier, 1996). One of the most used concepts of Space Syntax in the integration, which represents the potential flow generation in the road axes and is the focus of this paper. It is believed there is a strong correlation between urban space-form configuration and the way flows and movements are distributed in the city, considering nodes articulations and the topological location of segments and streets in the grid (Holanda, 2002; Medeiros, 2006). For urban transportation studies, traffic-related problems are often investigated and simulated by assignment models – well-established in traffic studies. Space Syntax, on the other hand, is a tool with few applications in transport (Barros, 2006; Barros et al, 2007), an area where configurational models are considered to present inconsistencies when used in transportation (cf. Cybis et al, 1996). Although this is true in some cases, it should not be generalized. Therefore, in order to simulate and evaluate Space Syntax for the traffic approach, the city of Brasília was used as a case study. The reason for the choice was the fact the capital of Brazil is a masterpiece of modern urban design and presents a unique urban layout based on an axial grid system considering several express and arterial long roads, each one with 3 to 6 lanes,

title	Frameworks for Practical Parametric Design in Architecture
doi	https://doi.org/10.52842/conf.ecaade.2008.847
source	Architecture in Computro [26th eCAADe Conference Proceedings / ISBN 978-0-9541183-7-2] Antwerpen (Belgium) 17-20 September 2008, pp. 847-854
summary	This paper is aimed at the development of a theoretical framework that addresses practical applications of parametric design that have been observed in architectural practice. Existing theoretical frameworks are not aimed at addressing this specific use of parametric tools but do provide a set of key themes. Based on these themes a simplified structure is presented here as a means for tackling architectural design development tasks. This is then used in order to examine a case study; the parametric design tasks involved in the design development and documentation of the new Lansdowne Road Stadium in Dublin Ireland. This project was undertaken in collaboration with HOK Sport Architects. The findings from this examination are used to discuss proposals and implications for a practical framework for parametric design in architecture.

title	Collaborative Financial Feasibility With CAAD For Residential Development
doi	https://doi.org/10.52842/conf.caadria.2008.594
source	CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 594-600
summary	Computer Aided Architectural Design software is a necessary tool for the architectural design of a visible object or model. In residential development, an estimation of time/cost corresponding to the design is needed in order to complete its successful project. But available feasibility supporting tools usually lacks ability to share their information. To solve this limitation, this research proposes a design of Graphic User Interface (GUI) for collaborative financial feasibility through an architectural design process in housing project. The development of the GUI starts from collecting some information and requirement from National Housing Authority of Thailand. A heuristic decision making approach based on financial analysis are then designed for both design processes and feasibility processes of the project. Finally, design of the GUI is an integration of CAAD engines, design standards and financial feasibility analysis. Proposed GUI for collaborative financial feasibility is also tested and verified with some information from sample past projects of the National Housing Authority. From the experimental results, This GUI allows designers to improve the design of the project in real-time by inspecting the result of their design via the part of the architectural design-oriented GUI called myMonitoring and Scratch Pad. Together with planning, collaborative financial feasibility is focusing on the four main financial parameters which illustrated the possible chance of the project: Net Present Value (NPV), Benefit-Cost Ratio (B/C), Internal Rate of Return (IRR), and Payback Period. The core system was developed on Java Technology such as JSP and Swing empowered by 3D game engine. In addition, “Virtools” as an authoring tool was applied to improve interactive 3D virtual environment and explore rapid online system prototyping.

source	International Journal of Architectural Computing vol. 6 - no. 3, pp. 261-277
summary	This paper describes a system for searching and retrieving urban design drawings developed or contracted by public or governmental entities. We assume that in governmental public programs with similar goals recreating solutions is a daily action, which is, clearly, an unnecessary waste of time and resources. The system presented in this paper aims at concentrating and organizing this information in order to allow urban planners and designers to search for existing solutions to their projects and answers to their current needs.

title	Architectural Brand valuations through a tag-based learning machine.
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	Brand is a set of associations related to an object from a particular source (Libai 2008). Such an object can be a product, person or service. Architecture is both service and product. However architectural Branding has never been clearly defined. This probably happens due to the lack of tools to measure the architectural Brand. This paper explores a direction to evaluate the architectural Brand by using computational methods in order to offer a better understanding regarding the awareness, reputation and prominence of the architectural firm. The methodology is based on case studies in which the brands of different types of architectural firms are analyzed, measured and compared to each other through a two-part process: a. the development of one tool to statistically measure the architectural Brand and b. the interpretation of the results of the measurements. a. Learning machine In order to make these brand measurements within a specific group of people or images, this paper develops an interactive tool that uses an image database. The tool constitutes a learning machine; it makes a hypothetic hierarchical categorization of the image database into + and – using an initial sample and it proposes to the user the first image of the list; finally, the user validates the image by confirming or not the machine’s guess. In this image database, each image is described as an array of attributes (tags). Tags can be generated either by the architectural firm itself or can emerge by users. b. Evaluation of results This interactive, user-friendly tool is drawing a user’s preference by proposing similar images from the database based on a learning process from the user input (initial sample and feedback); alternatively, it can be used as a questionnaire for quantitative research. Moreover, this tool categorizes photos of similar content. This research focuses on the following issues as parameters of the effectiveness of the process: o Simplicity of the database organization through computation. o Top-down Vs. Bottom-up tagging of works/ images mechanism. o Future use of the image database. o Transformation of the image database while becoming larger. o “Market” segmentation or not. o Combination of the tool with other Brand measurement tools. o Combination of the tool with other image databases. The outcome of this approach can provide an analysis and metric of the brand strength of different architectural firms. Furthermore, it can help architectural firms to understand better how they are perceived by others in order to improve their brand image and associations.

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	Exploring Weaire-Phelan through Cellular Automata: A proposal for a structural variance-producing engine
source	SIGraDi 2016 [Proceedings of the 20th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-956-7051-86-1] Argentina, Buenos Aires 9 - 11 November 2016, pp.710-714
summary	Complex forms and structures have always been highly valued in architecture, even much before the development of computers. Many architects and engineers have strived to develop structures that look very complex but at the same time are relatively simple to understand, calculate and build. A good example of this approach is the Beijing National Aquatics Centre design for the 2008 Olympic Games, also known as the Water Cube. This paper presents a proposal for a structural variance-producing engine using cellular automata (CA) techniques to produce complex structures based on Weaire-Phelan geometry. In other words, this research evaluates how generative and parametric design can be integrated with structural performance in order to enhance design flexibility and control in different stages of the design process. The method we propose was built in three groups of procedures: 1) we developed a method to generate several fits for the two Weaire-Phelan polyhedrons using CA computation techniques; 2) through the finite elements method, we codify the structural analysis outcomes to use them as inputs for the CA algorithm; 3) evaluation: we propose a framework to compare how the final outcomes deviate for the good solutions in terms of structural performance and rationalization of components. We are interested in knowing how the combination of the procedures could contribute to produce complex structures that are at the same time certain rational. The system developed allows the structural analysis of structured automatically generated by a generative system. However, some efficient solutions from the structural performance point of view do not necessarily represent a rational solution from the feasibility aspects.

summary	In this research project we explore the defined design and application of digitally fabricated wall panels for room-acoustical architectural interventions. In Particular, we investigate the room-acoustical criteria applying to everyday used spaces. We present a digital design and fabrication process developed to create non-standardised panels and two case studies which apply this process on the acoustical improvement of a specific room situation. Our aim is to find correlations between digitally fabricated surface structures and sound- aesthetical characteristics, in order to utilise these for the architectural design.

title	Rivalry between the collective use of IT tools and working methods of design teams Comparison of research outcomes
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	Nowadays a high variety of IT tools is available for communication purposes in design processes on individual and group level. Despite this, the exchange and sharing of design documents collectively in design and engineering teams might be limited mainly, due to habits, preferences, working methods and rivalry between the collective use of IT tools in such product development. Changes in habits and preferences for collective use of IT tools might be realized by training and management power. However, adoption of collectively to be used tools, like project websites, is depending heavenly on the attractiveness for users in daily work. Based on empirical research outcomes it is indicated that rivalry between collective used tools and differences in working methods of users might be main barriers for attractiveness of these tools in daily work. Applying a framework for analyzing and categorizing of the frequency of use of IT tools for team communication, the authors explain the appearance of rivalry between tools, limiting the effectiveness in daily work and not affecting team communication and performance. By comparison of working methods in different sectors authors explain the necessity of changes in working methods in design and engineering in the building & construction industry on organizational and inter-organizational level for successful adoption of collectively to be used IT tools in team communication.

source	CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 510-517
summary	With this project I propose that embodiment can be more emphasized and better supported in space-design frameworks. This paper presents background on several theories of embodiment since the beginning of the twentieth century to recent developments of the concept in tangible and social computing and anticipate that this reveals pathways for designing new embodiment framework systems for architecture. I suggest that architecture and interactive computing can share a common theoretical foundation in embodied interaction. The main thesis is for designers to use the body as an interface to understand how the interaction between a person and his/her surroundings arises and how our embodiment reveals other rich spatial qualities during the conception phase of design. This paper proposes a conceptual framework for embodied interaction based on the creation of real-time systems in order to instigate a framework for interactive processes that can help designers understand architecture phenomena and the performance of space. I present a design experiment on embodied performance space entitled “Body Tailored Space” where the boundaries of the human body are metaphorically extended into surrounding membranes.

summary	The core idea of this research is the incorporation of the morphogenetic principles found in natural systems in the generation of fibre-composite structures by exploiting, at the maximum, the intrinsic performative capacities of the material system in use. The intention is the integration of form, material, structure and program into a multi-performative system that will satisfy simultaneously several, even conflicting objectives, in order to achieve an optimal compromise. This process involves the combination and implementation of concepts and methods based on precedent studies in the field of biomimetics, as well as form-finding digital and physical experiments that inform a coherent design methodology, leading to a structural system able to be fabricated using cutting-edge technology.

title	Designing (tools (for designing (tools for ...))))
source	RMIT University, Melbourne
summary	Outcomes of innovative designing are frequently described as enabling us in achieving more desirable futures. How can we design and innovate so as to enable future processes of design and innovation? To investigate this question, this thesis probes the conditions, possibilities and limitations of toolmaking for novelty and knowledge generation, or in other words, it examines designing for designing. The focus of this thesis is on the development of digital design tools that support the reconciliation of conflicting criteria centred on architectural geometry. Of particular interest are the roles of methodological approaches and of biological analogies as guides in toolmaking for design, as well as the possibility of generalising design tools beyond the contexts from which they originate. The presented investigation consists of an applied toolmaking study and a subsequent reflective analysis using second- order cybernetics as a theoretical framework. Observations made during the toolmaking study suggest that biological analogies can, in informal ways, inspire designing, including the designing of design tools. Design tools seem to enable the generation of novelty and knowledge beyond the contexts in and for which they are developed only if their users apply them in ways unanticipated by the toolmaker. Abstract The reflective analysis offers theoretical explanations for these observations based on aspects of second-order cybernetics. These aspects include the modelling of designing as a conversation, different relationships between observers (such as designers) and systems (such as designers engaged in their projects), the distinction between coded and uncoded knowledge, as well as processes underlying the production and the restriction of meaning. Initially aimed at the development of generally applicable, prescriptive digital tools for designing, the presented work results in a personal descriptive model of novelty and knowledge generation in science and design. This shift indicates a perspective change from a positivist to a relativist outlook on designing, which was accomplished over the course of the study. Investigating theory and practice of designing and of science, this study establishes an epistemological model of designing that accommodates and extends a number of theoretical concepts others have previously proposed. According to this model, both design and science generate and encode new knowledge through conversational processes, in which open-minded perception appears to be of greater innovative power than efforts to exercise control. The presented work substantiates and exemplifies radical constructivist theory of knowledge and novelty production, establishes correspondences between systems theory and design research theory and implies that mainstream scientific theories and practices are insufficient to account for and to guide innovation.

title	INTERVIEW TECHNIQUES FOR MEASURINGINDIVIDUALS’ MENTAL REPRESENTATIONSSPACE-TIME CHOICESAn outline of three IT-based survey methods

summary	A better exploration of human decision making is a necessary condition to understand individual activity-travel choices. With the advent of mental model theory a conceptual framework of individuals’ causal knowledge of the environment and its links to the behavioural choice outcome was available. Accordingly, interview techniques had been developed in order to elicit mental representations from individuals’ mind. Although these techniques delivered reliable and useful results, it turned out quickly, that they could not be applied to large-scale surveys. Hence, this paper will report on the development of three IT-based interview techniques, which are promising avenues to measure mental representations in an efficient and flexible way.

title	Knowledge Acquisition in Parametric Model Development
source	International Journal of Architectural Computing vol. 6 - no. 4, 435-451
summary	This paper addresses the development of parametric models in contemporary architectural practice. A parametric model can be regarded as a representation of a solution space and in order to structure this, a description of the problem is required. Architectural design tasks are typically ill structured, the goals may not be defined and the means unknown. Moving from an incomplete problem description to a functional parametric model is a difficult task. This paper aims to demonstrate that through a combination of knowledge acquisition and capture a parametric model can develop from an incomplete problem description. This demonstration draws on existing strands of design theory which are then used to outline a theoretical framework. This framework is then used to examine a case study of a live project and practical examples of the described theory in action are given. The practical observations are the result of a case study involving the author as a participant and observer working with HOK Sport to develop a cladding geometry solution for Lansdowne Road Stadium in Dublin.

summary	The goal of the paper presented below is to discuss partial results of a research which has been financed by the state sponsored agency FAPESP since 2007. Inserted in the research line Design Process, it aims to analyse connections between design process in electronic art and architecture, concerning the creation of mixed media spatialities, as well as present how each field can get the benefits from this analyses. Based on Grounded Theory methodology, a method of qualitative research which aims to understand “reality” from the meanings attributed by people for their experiences, the research has been started collecting data from bibliographical references, interviews with media artists, theoreticians and curators of electronic art and visits to media labs. Interviews and visits of media centers were taken in Europe while the researcher was as an exchange student in the Interface Culture Department in Kunstuniversität Linz, from March to September of 2008. By crossing data collected from the interviews and visits, with the cybernetic social system theory by Niklas Luhmann, and the discussion of an example of mixed media spatiality creation in the art field, this paper analyses how creative processes in digital era depends on different interdisciplinary relationships and how collaborative approaches are needed nowadays in the arts and architectural areas, seeing that artworks are always being influenced by their respective specific “mediality”. The aim of this paper is to discuss the relevance of the use of the cybernetic theory in digital culture, when concepts like participation, interaction and communication are some of the keywords, towards a “collective and distributed authorship”, and their reflects in the contemporary spatiality. The special interest in the comparison of art experience and second order cybernetics as a reference to architecture field is one of the findings of the paper. And, concerning the practical implication, due to cybernetics’ constant questioning of viability, adaptability and recursion, it should be able to point some ways to architects and artists´ works, especially if we consider that they never work in “ideal” conditions.

summary	Technically-oriented architectural spaces today are getting complicated because the building contains a number of electronic facilities and complex structures. Furthermore, the advent of the ubiquitous environment enabled the building to provide various services to users and accelerated the importance of architectural visualization as problem-solving and communicating tools. It is recommended that architectural visualization has been more intuitive and effective to support the design decision and collaboration. In this manner, this paper intends to define the role of current architectural visualization with considerations of previous research and related works in the practical field and proposes the appropriate method of architectural visualization. Also, in order to evaluate our idea, we recommend a prototype system based on dynamic and semantic representation with the avatar. It is a kind of simulator for the design of ubiquitous smart space and can deliver to users the better comprehension in how technological oriented space will be constructed and utilized.
