title A FRAMEWORK FOR BUILDING DESIGN PROCESS MODELING WITH PARAMETER-BASED DESIGN STRUCTURE MATRICES
source In C. J. Anumba (Ed.), Innovative Developments in Architecture, Engineering, and Construction. (pp. 25-31). Rotterdam: MillPress
summary Architecture/Engineering/Construction (AEC) industry is one of the multidisciplinary domains in which collaboration among related parties is utmost important. While the knowledge needed for building processes are distributed among the different participants from diverse disciplinary backgrounds, the product of their activities, i.e. the building itself, must be highly integrated. Despite the intense flow of information between design professionals, there is a lack of research to better understand and manipulate these flows. Furthermore, most of the current process modeling tools in the AEC industry do not enable analyses of iteration in the process and they represent the process at high levels with very little information at lower levels. In order to resolve the issues mentioned above, this paper introduces the use of parameter-based dependency structure matrix as a process modeling and system analysis tool for building design. The method reveals insights into the process structure, optimum sequence of parameter decisions, iterative cycles and concurrency in the process. A knowledge management framework for parameter-based DSM applications is proposed and the application of the framework is demonstrated through a real life building design problem.

title The Digital Environment of Urban Dynamic Analysis
source International Journal of Architectural Computing vol. 1 - no. 3
summary Urban sprawl and complexity are increasing at an alarming rate causing huge energetic waste and affecting the quality of life of people and life on earth in general. This paper proposes Urban Dynamic Analysis as a feasible approach to address this negative phenomenon. Urban Dynamic Analysis is a multidisciplinary holistic method that inquires into temporal relations between structures and related characteristics in cities. A range of simulation tools are being adapted and developed aiming to assess different morphological configurations of urban spaces, to improve the welfare of citizens and to optimise energy consumption. All these tools are based on digital image utilization, with simple computational techniques.

title Mass-Customization in the Design of 4,000 Bus Stops
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. 265-278.
summary In Hawaii, ‚"TheBus‚" has been a main transportation system since 1971. Considering the high cost of living in Hawaii and the absence of a rail system, the use of ‚"TheBus‚" has been an instrumental vein of the city life in Honolulu with rhythmical pauses at about 4,000 bus stops in Honolulu. However, existing undifferentiated bus stops are developed from a cost effective mass production system so that they have been problematic for satisfying specific needs from various site conditions. In this research, an integrated computational method of mass-customization for designing 4,000 bus stops is introduced. According to various site conditions, the design of each bus stop is customized. Unlike the mass‚Äêproduced bus stops commonly seen in cities today, the proposed computational method in this paper produces bus stop design outcomes that fit into the physical characteristics of the location in which they are installed. Mass-customization allows for the creation and production of unique or similar buildings and building components, differentiated through digitally‚Äêcontrolled variation (Kolarevic, 2003). The employment of a computational mass‚Äêcustomization in architectural design extends the boundary of design solutions to the satisfaction of multi-objective requirements and unlimited freedom to search alternative solutions (Duarte, 2001; Caldas, 2006). The computational method developed in this paper consists of 1) definition of a prototype, 2) parametric variation, 3) manual deformation, and 4) simulation based deformation. The definition of a prototype is the development of a basic design to be transformed for satisfying various conditions given from a site. In this paper, the bus stop prototype is developed from the analysis of more than 300 bus stops and the categorization of the existing bus stops according to their physical conditions, contextual conditions, climatic conditions, and existing amenities. Based upon the outcome of the analysis, the design variables of a bus stop prototype are defined. Those design variables then guide the basic physical parameters for changing the physical configuration of the prototype according to a given site. From this, many possible design outcomes are generated as instances for further developments. The process of manual deformation is where the designer employs its intuition to develop the selected parametric variation. The designer is compelled to think about the possible implication derived from formal variation. This optional process allows every design decision to have a creative solution from an individual designer with an incidental quality in aesthetics, but substantiated functional quality. Finally the deformation of the selection is guided and controlled by the influence of sun direction/ exposure to the selection. The simulation based deformation starts with the movement of the sun as the trigger for generating the variations of the bus stop prototype. The implementation of the computational method was made within the combination of MEL (Maya Enbedded Language), autodesk MAYA and Ecotect environment.

title Spatial Understanding in Immersive Virtual Environments
source International Journal of Architectural Computing vol. 1 - no. 4
summary In this study, we examined the perception and understanding of spatial volumes within immersive and non-immersive virtual environments by comparison with representation using conventional media. We examined the relative effectiveness of these conditions in enabling the translation to a tangible representation, through a series of design experiments. Students experienced, assessed, and analysed spatial relationships of volumes and spaces and subsequently constructed real models of these spaces. The goal of our study is to identify how designers perceive space in Virtual Environments (VEs). We explore issues of quality, accuracy and understanding of reconstructing architectural space and forms. By comparison of the same spatial performance task undertaken within a Head Mounted Display, screen-based and real 2D environment, we are able to draw some conclusions about spatial understanding in immersive VE activity.

summary This paper explains the experience performed by a group of architecture students during a short term worksop, trying to explore the potentials of new approaches and digital technics applied to urban and architectural design. The main purposes were: the inclusion of objetive information and quantitative data of material significance in order to assist the generation and structuring of the design process. The notions of "diagram", "field conditions", "contextual logistic" and "animation" were the conceptual categories employed to approach the dinamic conditions and time related logics as critical aspects of the flexibility associated with material organizations.

title The pattern of Internet use for information management by architectural practices in the UK
source Cardiff University, Welsh School of Architecture Cardiff, UK
summary In recent history, architects have experienced problems related to the use and management of new innovations. The Internet presents one such challenge. It offers considerable expansion in types of communication and sources of business information and connects people and businesses around the globe. As is argued in this research, these services could play a positive role in architectural practice. This research examines the use of the Internet by architectural practices in UK in order to reveal how aware they are of the opportunities it presents, the extent to which they are taking advantage of them, and the problems they are experiencing. A field study was conducted of two types of practices: RIBA private practices and local authority practices. A number of research tools were used to inspect how these practices are using the Internet to manage various types of information that used and produced in the practice, namely: the acquisition of web information, the exchange of the practice’s information through the web and the presentation of the practice’s information on the web. Explanations for the results were sought by correlating variables from the questionnaire study, using simple statistical tests. The field study shows that many Internet services are unpopular among architects, and that practices have problems in adopting and using the technology. The pace at which the Internet is being absorbed and accepted by practices is slow. The study suggests that possible causes are: the little knowledge of users’ about IT, the poor resources of the practice, and old or imperfect Internet installations and the absence of the Internet support to the architect’s activities. The research argues that there are a number of links between these negative factors which make the practice unable to utilize the Internet and to manage the practice’s information through the Internet. To break these links, the research suggests that practices should adopt a specific management strategy to promote more utilization of Internet services in the office and to manage information. Practices need to make certain changes to the way they manage the Internet and work with it, if they plan to integrate the Internet more successfully into their practice. The research discusses techniques for improving practice management which would help practices to digest Internet technology and to use it more effectively in the practice.

title Close encounters of the architectural kind
source Design Studies, Volume 24, Issue 4, 2003, pp. 313-326
summary Throughout their career architects collect an extensive record of architectural cases, which they use as a source of inspiration and knowledge during design. Being novices, student architects do not yet have such a record. In order to compensate for this lack of knowledge, teachers in architecture engage their students into realistic yet simulated projects and introduce them to relevant architectural precedents for these projects. Within the realm of AI, case-based reasoning (CBR) stresses the importance of cases too. So far, however, applications that flow from CBR research have rarely found their way into architecture. The experiment that is reported in this article examines the conditions under which CBR technology can be useful in architectural education. The results show that in order for students to benefit from this technology, it should supply cases that are closely related to the project at hand. These results are consistent with psychological theories of knowledge representation in novices.

summary Confronted with the changing educational landscape, our architecture program faces the need for integration: integration of CAAD-related subjects into the curriculum, but above all integration of the curriculum as such. This inspired the idea to view ICT as an ally in tuning various courses to each other by what unites them all: the concrete architectural project. Within the scope of a two-year pilot project, we examined whether and how the use of ICT could improve the integration between a exemplary course, seminar and design studio. Despite evident links between the three, students and teachers used to consider these as separate entities. Without ignoring the individual character of each, the pilot project aimed at initiating a process of synergetic and cumulative knowledge development, whereby ICT played various roles. Across the board, the objective to stimulate a synergy among different components in the curriculum has been partially realized. Questions arise, however, as to who will take care of the extra tasks brought about by the use and maintenance of ICT after the project has ended.

summary This paper is aimed to establish the visual links of correlations among design cases in a case library for architecture, CBA. The study found that the keywords extracted from cases usually present certain information related to design concept, knowledge, problems or situations; and therefore, the links of those keywords can represent the correlations of those concepts or knowledge. Then the links of keywords can help users to understand the correlation between those concept or knowledge and further to prompt the correlation of cases where contain the design concepts or knowledge. Based on the previous works, the collected cases are clustered by the semantic relationships of keywords extracted from cases and the links of cases are presented with the links of keywords. Furthermore, the links of those keywords and the ranking of those linkages can be visualized to represent the correlation among cases for helping users to retrieve appropriate cases and facilitate associative reasoning based on the information embedded in those cases. The interface implementation and feedbacks are discussed.

summary This paper deals with the CUMINCAD-repository (Cumulative Index on CAD), which was set up in 1998 and has served the CAAD-community since then as an important source of archived domain related information. CUMINCAD contains over 5,000 entries in the form of publications in the field of Computer Aided Architectural Design. The number has been growing steadily over the years. To date only advanced search mechanisms have been provided to access these works. This may work out well for a just-in-time location of a reference, but is inadequate for just in case browsing through the history of CAAD. For such applications, a hierarchical browsing interface, like one in Yahoo or DMOZ.org is envisioned. This paper describes how the keyword categories were defined and how a moderate, distributed effort in defining the categories will allow machine-identified classification of the entire data set. The aim of the paper is to contribute to building up a wide spread consensus on what the appropriate keyword categories in CAAD are, and what sub-topics should sit below the main keyword categories.

title ArDOT: A tool to optimise environmental design of buildings
source Building Simulation 2003 (Eighth IBPSA Conference). Eindhoven, Netherlands
summary Environmental design of buildings involves ‘finding the optimum’ solution satisfying predefined objective(s) (e.g., reduction in operating/capital cost, maximisation of daylighting etc.). A number of computer based simulation models exist to assist professionals in finding this optimum through building performance assessment. Contemporary practices involving building simulation require enormous effort to prepare input, extract output, and visualize data, which restricts designers from realizing the full potentials offered. In most cases, rules of thumb are applied and experienced guesses are made; simulation software is used only to validate the assumptions, which do not necessarily lead to the intended optimum. Moreover, these tools have been developed as simulation engines, which is inadequate to visualize the compounded and interdependent effect of a large number of design variables.

The authors believe that to realize the potential offered by building simulation software, a new breed of DBSs (Decision Based Systems) is needed coupling existing simulation engines with formal optimisation methods through neutral data standards (BPM – building product models) for seamless integration. This paper first elaborates on the previous attempts at solving integration issues related to the design process and simulation; also attempts at finding the limitations. Secondly, formulation of design problems as optimisation has been discussed with reference to the different stages of design. Thirdly, for effective integration of activities among stakeholders and processes, the use of client/ server oriented building product model has been proposed to overcome the limitations of file-based prototypes. Analysis and discussions based on the above aspects form as justification for ArDOT, an Architectural Design Optimisation Tool under development at IRUSE, National University of Ireland, Cork. Combining all three aspects into one makes ArDOT unique, which is essentially an enhanced decision making tool for the design of energy efficient buildings.

summary In this paper, we describe the research we undertake to investigate the perception and comprehension of spatial volumes within immersive, non-immersive virtual environments and physical models and their translation to a tangible representation. We set up two related design experiments to investigate the outcome of creation, interpretation and communication of architectural design. One, being the analysis of a cubic structure, based on three-dimensional (3D) interlocking volumes and spaces; and the other, being the design of a 3D-maze together with text -based communication. Collaboratively participants create, assess and analyse spatial relationships of volumes and spaces of a 3D maze structure or construct models of these spaces. The objective of our study is to identify how designers perceive space in Virtual Environments (VE) and communicate design ideas by using VE versa conventional methods of two-dimensional depictions such as paper and pen or 3D representations such as physical models. We investigate issues of quality, accuracy, understanding, communicating and rebuilding of designed or experienced architectural compositions.

summary As light is increasingly perceived as a factor of quality of urban life, it is not surprising that cultural heritage buildings and even civil engineering works are being more and more often illuminated at night. The designers of the projects are revealing a nocturnal vision of the buildings which is often a reflection of the architecture: rhythm, pattern, evenness, symmetry, composition, axes, and so on. The idea of developing a "lighting-modeller" is based upon this assertion. Thus, if we express the needs in terms of functionalities, we can conclude that the hierarchical structure of the architectural edifice can fit in with a "lighting-structure". As a result, concepts like hierarchy, linking, grouping, networking, linearity-polarity, are the basis of the objects and functions that are effective for the great majority of buildings and projects. This "lighting-modeller" can then lead beyond its simulation capabilities to become a design conception tool: hypothesis and variants are quickly realized and tested, and technical data (illumination data, visual comfort) can be obtained as well.

summary Architects and planners will increasingly have to deal with developments in urban sites where existing context is a critical part of their design considerations. It is therefore important that architects can envision the potential of emerging technologies as means to assist architectural design in the changing face of our build environment. The objective of this paper is to examine the opportunities which image-based modeling (IM) can offer to the architectural design in a context -rich urban built-environment by providing better means of representation of the design context. By drawing relations from the available precedents and the research findings, the paper provides insights into how IM application can create stronger visual awareness of the context, in order to assist design within such condition. This paper shows that the reliability of the IM models in terms of geometric accuracy and rendering quality decreases as the physical scale of the subject increases. The best result is generated from modeling small objects in studio environment as compare to creating larger architectural objects in exterior conditions.

summary By setting up collaborative design processes in architecture it is possible to considerably improve the integration of customer needs and ideas into the programming phase of a building project. Our design process includes active collaboration between customers, users and other stakeholders as well as the use of virtual environments in conceptual design. The output from the process is treated as visualised input to the architectural programming. The work presented focuses on developing digital tools to support this collaborative design dialogue. We have developed an extremely “easy to use” digital modelling tool called “ForeSite Designer”. The tool enables the users to build layouts of prefabricated components on a building site in 2D. This 2D layout can then instantly be exported to a lit-up real time 3D environment in the computer game “Half-Life.” ForeSite Designer has been used in a several design events with different settings. This paper presents the tool and one project where it was utilized. The results show that ForeSite Designer can promote dialogue and collaborative design work among the participants. We have also found that it is important how the virtual environment and its components are visually designed in order to support the dialogue and collaborative design work.

title THE CONTRIBUTION OF STRUCTURAL ACTIVITIES TO SUCCESSFUL DESIGN
source International Journal of Computer Applications in Technology , 16:2/3, pp. 122-126
summary Examining case studies in design teaching and their analysis; we identify the role of structural activities and other solution searching activities in design learning and problem solving. The case studies follow students working on the same problem under two conditions – one group is taught using traditional face-to-face teaching while the other group is additionally supported by a text-based web board. The design activities of two students were followed in each condition through a semester; followed by in-depth interviews at the end of semester. The results show that cases with above average design work involved more structural activities than the mediocre cases. It also showed that design problem dissections are more organized in the better cases. These successful cases engaged in textual expression of their design solutions. Computer tools for design should therefore support multiple representations of design work.

summary Design is the activity of making explicit proposals for a change from some existing state to some future state which more closely approximates to mankind's concept of the ideal. As such it embraces a wide spectrum of human endeavour; the outcomes of design activity are part and parcel of our everyday life and are determinants, for better or worse, of our man-made future. In common with all complex human functions the activity of design is ill-understood: it involves the most rational and systematic process of human thought and also the most intuitive and conjectural leaps within the human mind.

title Vision, Plan and Reality
source Aarhus: Aarhus School of Architecture, PhD Thesis
summary How come, that there is often a gap between what is considered good urban design and the built reality of the urban environment? This is the question which the thesis aims to investigate. It has often been stated that urban development can no longer be controlled, and the reason for this has been ascribed, among other things, to the power of the market, postmodern pluralism, or simply to the increased complexity of society. Yet, to decline on the capacity of urban design to guide urban development on such accounts, is to give up on urban design altogether. Rather, if urban design is incapable of achieving what it is aiming at, something must be wrong with it. Thus, the basic argument of the thesis is, that the answer to this question must be sought within urban design itself, rather than within the context in which it operates. In order to approach the research question, the thesis is organized as a twofold investigation, consisting of both an empirical study of the practice of urban design – in the form of a detailed case study of two urban development histories – and a study of the theoretical foundations for this practice. As urban design is regarded as an interdisciplinary activity, the theoretical study is organized as a threefold investigation of urban design theory, planning theory, as well as urban theory. As urban design in practice must consider what the built environment should be like as well as how it is developed, it must include normative as well as procedural considerations. Thus, the issues of normativity and process are central to the understanding of urban design. These issues therefore constitute the foci of both the empirical and the theoretical study.

summary Architectural education has often been criticised for producing students that seem to lack the practical knowledge needed to create architecture that is fit for purpose, safe and a delight to users. Unfortunately, owing to the complexities of society, technology, practice and academia, design teachers are struggling to balance the teaching of basic practical concerns for making architecture with teaching students how to think critically and abstractly. This paper suggests a resolution that places the computer at the center of the relationship between student and tutor. It suggests a digital teaching tool that detects and interprets the marks students make when sketching. The digital design coach then presents the student with related issues allowing a comprehensive reading of the digital sketch. The student, more aware of the issues involved, engages in more intelligent and wellinformed dialogue with tutor.

title Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools

summary Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call “business views”. We propose a 4 steps-method to compose business views. The first step identifies the users’ business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user’s interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.
