title The Meaning of BIM

summary The paper is a position paper, not a report about a research project. It concerns the paradigm-shift that is taking place in the CAAD software and its implications for the business of architecture and more importantly, for the education of future members of the profession. Twenty years ago the use of CAAD software as a replacement for hand drafting was starting. Since then the transformation is complete: hardly a final project in the universities is drawn by hand. Currently, we are witnessing a second paradigm shift and its name is BIM. The meaning of BIM is rooted in two significant differences to current CAAD software and this will have implications for teaching and practicing architecture. The first difference is the way the software structures information in the CAAD file. The standard way to save CAAD information was to organise simple geometric objects according to membership in groups and to sort them according to a layer-metaphor, which primarily controlled the visibility of the geometric elements. Three-dimensional modelling is/was nothing more than the same structure with a more complex geometry. BIM software changes this structure by storing classes of geometries and then to store the specific values of individual geometries according to factors that can be determined by external or internal logical factors. The implication for architects is that we have the chance to be the people in control of the building information model, so long as we invest the time and energy to fully understand what is happening to the building information during the planning process. If we ignore this, the real danger exists that the last control of the building’s final configuration will be usurped. As educators we are currently teaching students that will be leaving the schools in 2012 and beyond. By then, the paradigm-shift will be in full motion and so it behoves us to consider which skill sets we want the next generation of architects to possess. This means not just teaching students about how to use particular BIM software or how to program a certain parametric/genetic algorithm in a form-finding process. We need to teach our students to take the leadership in building information management and that means understanding and controlling how the building information flows, how the methodologies that are used by the consulting engineers affect our building models, and knowing what kind of logical inconsistencies (internal or external) can threaten the design intention.

title Automated Cost Analysis of Concept Design BIM Models

summary AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.

summary The paper discusses mathematical form generation as an academic methodology to develop new approaches to architectural design. The academic design studio ‘Math objects’ investigates the relationship between complex 3d-surfaces and mathematics in order to expand the formal repertoire of architecture. It claims that the process of form generation can be seen as an autonomous entity, which is independent from an overall strategy or any a priori meaning. Architecture has always originated from a concept, eventually progressing towards a certain form. This methodology has been reversed. The paper discusses two studios undertaken in the last year, led by Daniel Baerlecken and Olaf Kobiella at the TU Braunschweig, Germany.

title Computing And Manipulation In Design - A Pedagogical Experience Using Symmetry
source SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary The concept of symmetry has been usually restricted to bilateral symmetry, though in an extended sense it refers to any isometric transformation that maintains a certain shape invariant. Groups of operations such as translation, rotation, reflection and combinations of these originate patterns classified by modern mathematics as point groups, friezes and wallpapers (March and Steadman, 1974). This extended notion represents a tool for the recognition and reproduction of patterns, a primal aspect of the perception, comprehension and description of everything that we see. Another aspect of this process is the perception of shapes, primary and emergent. Primary shapes are the ones explicitly represented and emergent shapes are the ones implicit in the others (Gero and Yan, 1994). Some groups of shapes known as Semantic Shapes are especially meaningful in architecture, expressing visual features so as symmetry, rhythm, movement and balance. The extended understanding of the concept of symmetry might improve the development of cognitive abilities concerning the creation, recognition and meaning of forms and shapes, aspects of visual reasoning involved in the design process. This paper discusses the development of a pedagogical experience concerned with the application of the concept of symmetry in the creative generation of forms using computational tools and manipulation. The experience has been carried out since 1995 with 3rd year architectural design students. For the exploration of compositions based on symmetry operations with computational support we followed a method developed by Celani (2003) comprising the automatic generation and update of symmetry patterns using AutoCAD. The exercises with computational support were combined with other different exercises in each semester. The first approach combined the creation of two-dimensional patterns to their application and to their modeling into three-dimensions. The second approach combined the work with computational support with work with physical models and mirrors and the analysis of the created patterns. And the third approach combined the computational tasks with work with two-dimensional physical shapes and mirrors. The student’s work was analyzed under aspects such as Discretion/ Continuity –the creation of isolated groups of shapes or continuous overlapped patterns; Generation of Meta-Shapes –the emergence of new shapes from the geometrical relation between the generative shape and the structure of the symmetrical arrangement; Modes of Representation –the visual aspects of the generative shape such as color and shading; Visual Reasoning –the derivation of 3D compositions from 2D patterns by their progressive analysis and recognition; Conscious Interaction –the simultaneous creation and analysis of symmetry compositions, whether with computational support or with physical shapes and mirrors. The combined work with computational support and with physical models and mirrors enhanced the students understanding on the extended concept of symmetry. The conscious creation and analysis of the patterns also stimulated the student’s understanding over the different semantic possibilities involved in the exploration of forms and shapes in two or three dimensions. The method allowed the development of both syntactic and semantic aspects of visual reasoning, enhancing the students’ visual repertoire. This constitutes an important strategy in the building of the cognitive abilities used in the architectural design process.

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.

title What is the state of digital architectural design?
source SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary What is the state of digital architectural design? The ubiquity of the computer in architecture can be seen in the many computer based presentations from famous architectural practices. BIM (Building Information Modelling) is the key word and we can see implementations in very ambitious projects all over the world. Glossy magazines show the results of this kind of architecture and predict that this is the future of our profession. But when we go out into the “small world” (in Europe) and talk with architects in small firms, there is a very different reality – at least at the moment. Although they all agree that the computer is crucial for their work, it is a love/hate relationship for many them. Most still use the computer purely as a drafting device and AutoCAD is still the dominant tool. Although many of them agree with the statement that you can use the computer for design, only a minority really use the computer as a design tool in the early design stages. To find out more about the reality of the use of computers in design in “small town Europe” we have been undertaking two different kinds of research over the past 4 years. The first one is an educational experiment using first year’s students to find out about the different qualities of designing with and without the computer. The results have been presented at previous conferences and, since we are doing a last run of these experiments this year, we will update and finalise our findings in this paper. To make it comparable to previous years, we use largely the same settings using the same type of student (first year) and the same project/site. We will also be comparing the results for students designing ‘freestyle’ ie in the way that they want against the previous years controlled groups. The second strand of research we have followed is a survey amongst practitioners and some of the above statements came out of this survey. We did this survey using a web questionnaire and focused on a particular region of Europe. Although the numbers of participants for this survey were quite satisfying we are re-running the survey in a different region and country to see whether there are significant differences. The results of our research and our experience as teachers and architects leads us to the main question of how we can give recommendations on how to teach design the new generation of architects. In many aspects most of the teaching that is done in our faculties is still strictly divided into teaching design and teaching computer skills. The crucial question for architectural education are the implications of the ubiquity of the computer will have especially in the field of design. We will try to give some suggestions for these effects this could have on our teaching. In the long run, this is the only way to avoid some of the pitfalls and bring the benefits of computers in design to our small architectural firms. The paper will present a summary of the results of our research and try to propose an answer to the question: “What is the state of digital design in small town Europe?”

summary Since Hugh Ferris in 1922 started with a series of massing studies the visualization of zoning planning began to be a topic for architects. Setbacks, plot area ratio, maximum building height, and other important attributes must be handled by the architect to fulfill the law, the needs of the clients and his own inspiration. This paper presents the problem of envelope design for high-rise isolated housing buildings, as well as a new Decision Support Systems tool based on the platform of a BIM software, that allows to simulate several options for building envelope according to the parameters required by the city Zoning Planning. These options deliver reliable data and geometry, to be analyzed in real time for the architects, engineers, builders, government and the client in the early stages of the building’s design.

source First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 35-40
summary The digital factor is a challenge to regain the meaning of Design on Architecture, in addition to evaluating its possible extension and transformations. Digital could be an answer for the actual needs of architectural design: Architecture should be digital because digital is profit. Digital could help to understand architectural design as ""verified conception"" through the concept of computational modelling: Architecture should be digital because digital goes in line and not against design tradition. Digital could enhance the didactic dimension, really important for students: Architecture should be digital because is actual. Digital offers cognitive and ontological value for the design and new skills for the designer: Architecture should be digital because digital is a catalyst of new and creativity. Digital reshapes constructed architecture introducing new aesthetic paradigms: Architecture should be digital because digital is the mental landscape as reference point for the actual theoretical phase of Architecture … There are several answers to the question: “Why Architecture should be digital?”, but without rigor and critical dimension cannot be any digital benefit in architectural landscape, and the main risk could be that the “representation” prevails over ""the fact"".

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.

summary This paper describes how designers can be supported in the early stages of designing through more flexible representations. It presents situated agency as a means to address this problem. Interpretation is a necessary process to give meaning to data before creating a representation. A framework for situated interpretation agents is outlined, with a focus on push-pull and the process of situation. An example for creating a CAAD representation from a raster image is used to illustrate this framework. This research lays a foundation for further work on situated interpretation agents.

summary This paper presents a new system that supports automatic path planning for walkthrough in building models, using information retrieved from Building Information Modeling (BIM). It can automatically generate a path that explores all or part of the rooms in a building. During a real-time walkthrough, users will be able to follow the path while interactively controlling their viewing angles. That way, users can take guided tours while simultaneously looking around to examine the spaces. We expect the system to be useful in design review because BIM models of design can be easily brought into the system that allows reviewers to start walkthrough immediately and interactively. The significance of the work is that the system has potential applications for visualization of complex building design.

summary This paper discusses the preliminary findings of an ongoing research project aimed at developing a technological, operational and strategic analysis of adopting BIM in AEC/FM (Architecture-Engineering-Construction/Facility Management) industry as a collaboration tool. Outcomes of the project will provide specifications and guidelines as well as establish industry standards for implementing BIM in practice. This research primarily focuses on BIM model servers as a collaboration platform, and hence the guidelines are aimed at enhancing collaboration capabilities. This paper reports on the findings from: (1) a critical review of latest BIM literature and commercial applications, and (2) workshops with focus groups on changing work-practice, role of technology, current perception and expectations of BIM. Layout for case studies being undertaken is presented. These findings provide a base to develop comprehensive software specifications and national guidelines for BIM with particular emphasis on BIM model servers as collaboration platforms.

title Creation of an Evolutive Conceptual Know-how Framework for Integrative Building Design
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. 435-450.
summary Low productivity of the building sector today is attributed to the fragmentation of tasks, disciplines and responsibilities, as well as to the resistance to adopt integrative work processes and digital means. The increased complexity of architectural projects and the aroused social consciousness for sustainable environment calls for integrative design collaboration. Thus, there is need for a Conceptual Framework combining work processes, technological means and policy aspects. According to the literature, integrative multidisciplinary design is a strategy resulting in high performance buildings nurturing sustainable way of living (Reed et al. 2009, Krygiel & Nies 2008). Responding to the increased technological complexity of our built environment, as well as to the objective of meeting multiple criteria of quality, both necessitating multidisciplinary collaboration during design, Building Information Modeling (BIM) is seen as a powerful means for fostering quality, augmenting productivity and decreasing loss in construction. Based on recent research, we can propose that a sustainable building can be designed through an integrative design process (IDP) which is best supported by BIM. However, our ongoing research program and consultations with advanced practitioners underscore a number of limitations. For example, a large portion of the interviewed professionals and construction stakeholders do not necessarily see a link between sustainable building, integrative design process and BIM, while in our opinion, their joint use augments the power of each of these approaches taken separately. Thus, there is an urgent necessity for the definition of an IDP-BIM framework, which could guide the building industry to sustainable results and better productivity. This paper defines such a framework, whose theoretical background lays on studies in social learning (activity theory and situated action theories). These theories suggest that learning and knowledge generation occurs mainly within a social process defined as an activity. This corresponds to the context in which the IDP-BIM framework will be used, its final objective being the transformation of building design practices. The proposed IDP-BIM framework is based on previous research and developments. Thus, firstly, IDP process was well formalized in the Roadmap for the Integrated Design Process‚ (Reed et al.) which is widely used as a guideline for collaborative integrative design by innovating practices in USA and Canada. Secondly, the National Building Information Modeling Standard (NBIMS) of the USA is putting an enormous effort in creating a BIM standard, Succar (2008) recently proposed a conceptual framework for BIM, but BIM ontology is still under development (Gursel et al 2009). Thirdly, an iterative design process bound to gating reviews (inspired from software development processes) was found to be successful in the context of multidisciplinary design studios (reported in our previous papers). The feedback from this study allowed for modifications and adjustments included in the present proposal. The gating process assures the good quality of the project and its compliance to the client's requirements. The challenge of this research is to map the above mentioned approaches, processes and technologies into the design process, thus creating an integrated framework supporting and nurturing sustainable design. The IDP-BIM framework can be represented by a multidimensional matrix linked to a semantic network knowledge database: - the axes of the matrix being the project timeline, the design process actors and building stakeholders (architect, engineers, client, contractor, environmental biologist, etc.), or different aspects of building performance (environmental, functional, social, interior environment quality, cost, etc.); and - the knowledge database providing multiple layers of semantic support in terms of process, domain knowledge, technology and workflow at a given moment of the project and for a given actor or building aspect. The IDP-BIM framework is created as an evolutive digital environment for know-how and will have an established protocol for regular updates. The paper will firstly present the state of the art in IDP and BIM. Secondly, it will expose the methodology used for the definition of the Framework, followed by a description of its structure, contents and digital implementation. Then, some scenarios for the use of the Framework will be shown as validation.

title Networked mobilities and new sites of mediated interaction
source First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 279-286
summary This paper takes point of departure in an understanding of mobility as an important cultural dimension to contemporary life. The movement of objects, signs, and people constitutes material sites of networked relationships. However, as an increasing number of mobility practices are making up our everyday life experiences the movement is much more than a travel from point A to point B. The mobile experiences of the contemporary society are practices that are meaningful and normatively embedded. That is to say, mobility is seen as a cultural phenomenon shaping notions of self and other as well as the relationship to sites and places. Furthermore, an increasing number of such mobile practices are mediated by technologies of tangible and less tangible sorts. The claim in this paper is, that by reflecting upon the meaning of mobility in new mediated interaction spaces we come to test and challenge these established dichotomies as less fruitful ways of thinking. The paper concludes with a research agenda for unfolding a ‘politics of visibility’, engaging with the ambivalences of networked mobilities and mediated projects, and critically challenge of taken for granted interpretations of networked mobilities.

summary Environmental and residential destruction caused by urbanization and land development raises a serious issue. In addition, advanced technology has quickly changed the structure of cities, followed by revolutionary changes are growing faster these days and this requires us to turn our attention into developing a symbiotic eco-city, which will make it possible for further sustainable development. In this regard, it grows much more important to manage a flood of information from various intelligent devices and systems for environmental maintenance. The structure and meaning of modern info-oriented cities have changed their focus from tangible materials and resources, or energy into intangible information and knowledge. Now it has become the most important on how to manage and utilize a vast amount of information in order to strengthen the competitiveness and improve the life quality. This study finds methods for an effective city management and planning, or visualization of information for ecology-friendly education in order to provide a comfortable city life and develop a cleaner city, by efficiently managing information on several ecology protection areas and their sauces of pollution in the centre of a city. The goal is to help city managers or planners to be better aware of environmental information related to their work.

title Tempus Fugit: Transitions and Performance in Activated Architecture
source First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 245-251
summary Meaning in architecture has isotropic instances of realization, one that can unfold during the design process and one that can be layered onto the artifact of the building; its components and forms constitute a communication flow that emerges from an abstract form of description to its physicality. The internal cognition of this condition situates the subject as the third element, one that identifies the meaning from the extant building to its proxy meaning. In this manner, narrative and aesthetics perform the actualizations (the spatial and physical sequences) so that the occupant may understand its implications.1 Architecture is thus a one-directional flow of information (the building is an inert object from which meaning is derived, its physicality is static). Even in process-driven design, the synthesis of the many and the ordered, is evident in the materiality of the architectural manifestation; the building, although presented as a result of process cannot be separated from the reading of the generative operations. 2 Rather than continue in this manner of constructing meaning from an extensive coding (joining a concept to an object) or the instantiation (producing one from a larger field of possibilities) from a version, we suggest a dialectic that is bi-directional, or even multinodal, that is, continually self-renewing in meaning and material configuration with the active participation of the occupant. This representation is one that is time-based.

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 A Study of The Effects of Placeness on Collaborative Virtual Workplace
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. 572-578
doi https://doi.org/10.52842/conf.caadria.2008.572
summary So far, there is no empirical study on how ‘placeness’ can affect virtual workplace model. This problem has continuously been overlooked. The research objectives are to verify the effectiveness of ‘workplace metaphor’ and to find out factors that constitute ‘placeness’, the properties of being a place, in collaborative virtual workplace. An experiment was conducted to test the framework. At the end, different virtual workplace settings can result in dissimilar user behavior in terms of teamwork and attitude toward the workplace as disparate settings imply different requirements on function, organizational culture, and social meaning. In conclusion, if architectural elements are carefully applied to the virtual office, it cans strengthen teamwork and enhances social interaction.
