title	Design Informatics: a case based investigation into parametric design scripting and CNC based manufacturing techniques
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	The research paper exemplifies a novel information integrated design technique developed at ONL (Oosterhuis and Lenard), Netherlands, specifically appropriated for manifesting complex geometric forms. The ‘informed design technique’, apart from being highly instrumental in conceptualizing and generating the geometric component constituting architectural form in a parametric manner, is also efficiently utilized for precise computer aided manufacturing and construction of the speculated form. Geometric complexities inherent in contemporary architectural constructs and the time spent in appropriation of such topologies, fueled the ‘informed design’ approach, which caters to issues of timely construction, precision oriented design and production (visual and material) and parametric modeling attuned to budgetary fluctuations. This designresearch approach has been tested and deployed by ONL, for conceiving ‘the Acoustic Barrier’ project, Utrecht Leidsche Rijn in the Netherlands and is treated as a generic case for exemplifying the ‘informed design’ technique in this research paper. The design methodology encourages visualizing architectural substantiations from a systems perspective and envisages upon a rule based adaptive systems approach involving extrapolation of contextual dynamics/ground data in terms of logical ‘rules’. These rules/conditionalities form the basis for spawning parametric logistics to be mapped upon geometric counterparts exemplifying the conception. The simulated parametric relations bind dimensional aspects (length, width, height etc.) of the geometric construct in a relational manner, eventually culminating in a 3D spatial envelope. This evolved envelope is subsequently intersected with a ‘parametric spatio-constructive grid’, creating specific intersecting points between the two. A pattern of points attained from this intersection: ‘the point cloud’ serves as a generic information field concerning highly specific coordinates, parameters and values for each individual point/constructive node it embodies. The relations between these points are directly linked with precise displacements of structural profiles and related scaling factors of cladding materials. Parallel to this object oriented modeling approach, a detailed database (soft/information component) is also maintained to administer the relations between the obtained points. To be able to derive constructible structural and cladding components from the point cloud configuration customized Scripts (combination of Lisp and Max scripts) process the point cloud database. The programmed scriptroutines, iteratively run calculations to generate steel-wire frames, steel lattice-structure and cladding panels along with their dimensions and execution drawing data. Optimization-routines are also programmed to make rectifications and small adjustments in the calculated data. This precise information is further communicated with CNC milling machines to manifest complex sectional profiles formulating the construct thus enabling timely and effective construction of the conceptualized form.

title	TOWARDS A WEB-BASED URBAN STREET SIMULATOR FOR PEDESTRIAN BEHAVIORS STUDY WITH AGENT-BASED INTERFACES
source	CAADRIA 2006 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Research in Asia] Kumamoto (Japan) March 30th - April 2nd 2006, 295-302

summary	The urban planning has largely placed the street users at the centre of infrastructural design, with significant implications for the perceived attractiveness of user environments. The urban designers faced with the task of designing such spaces and needs a tool that will allow different designs to be compared in terms of their attractiveness as well as their effectiveness. Therefore, this paper depicts an agent interface approach for creating a street simulator of user behaviors in urban street environments. We implemented the agent interface as individual-based simulation in the proposed project called "SCALE” (A Street Case Library for Environmental design). The project is demonstrated to find out differences between the simulation and the existed environment. The methodology and findings are reported.

title	A Constraint-Based Building Bulk Design Support
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 278-282
summary	We introduce an architecture practice-oriented implementation strategy of constraint-based methods called BDS (Building Bulk Design Support) to supporting bulk analysis during the architectural programming phase. We examine the optmization problem of site coverage and building massing according to a set of standard planning and zoning regulations, and try a problem solving approach based on the paradigm of constraint satisfaction problems. The case study, which is focused on the paticipatory planning of very low-income dwellings within the Latin American context, serves as testbed for a prototypical application of the adopted methodology. The BDS constitutes a novel approach on computer-aided bulk analysis, regarding this particularly relevant context of application. In the case of participatively planned low-income housing projects, efficiency regarding time and cost of planning directly affects dwellers’ quality of life, whereas elementary programming tasks such as bulk analysis lack appropriate state-of-the-art technological support. Traditional architectural planning methods demand a large domain-specific knowledge base and skillful planners. A planning process, which is mainly driven by the formulation of planning-relevant constraints and sets of solution alternatives, suggests to avoid architects’ traditional procedure of: 1. Create an (yet not necessarily valid) instance of the eventual design solution by directly choosing specific values for its shape parameters. 2. Evaluate its validity by confronting the designed model to a set of applicable constraints, which have to be satisfied. Instead, the constraint-based design methodology poses a search procedure that operates in a space of pertinent constraint sets. A computer-aided interactive search procedure to find more valid design solution alternatives in less time and with less effort is particularly qualified to supply efficient support for participatory planning activities carried out between dwellers and planners. The set of solutions for a building-bulk design problem is constrained by both a large complex system of planning and zoning regulations and the geometry of the eventual design solution itself. Given a considerable amount of such regulations, a regular size geometric constraint satisfaction system proved to be capable of providing a highly efficient, interactive modeling and evaluation tool for the formulation in real time of valid solution alternatives for an ordinary building-bulk design problem. A BDS implementation will constitute one system module of a larger integrated system model called Esther. A BDS tool shall interact with other functional modules, like e.g. the FLS (Floor plan Layout Support), which also uses constraint-based design methods.

title	Critical Environmentalism and the Practice of Re-Construction
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	This research focuses on the implications and applications of “critical environmentalism” as a quintessential epistemological framework for urban interventions while implementing digital applications that foster collective, round-table approaches to design. Essentially centering the environment (Umwelt) as an encompassing and interconnecting catalyst between multiple disciplines, philosophies, and modes of inquiry and technologies, the framework reciprocally fosters individual and critical identities associated with particular places, belief systems, and their participants as a primary concern. Critical environmentalism promotes a comprehensive, reciprocally unifying epistemological framework that can significantly inform architectural interventions and the tethered use of its technologies in order to foster increased vitality and a certain coinvested attention to the complexities of the greater domain. Grounding the theory in pedagogical practice, this paper documents an approach to urban design and architectural education, implemented as a case-study and design scenario, where divergent perspectives amalgamate into emergent urban configurations, critically rooted in the conditional partialities of place. Digital technologies are incorporated along with analogical methods as tools to integrate multiple perspectives into a single, working plane. Engaging the above framework, the approach fosters a critical (re)construction and on-going, co-vested regeneration of community and the context of place while attempting to dialogically converge multiple urban conditions and modes-of-thought through the co-application of various digital technologies. Critically understanding complex urban situations involves dialogically analyzing, mapping, and modeling a discursive, categorical structure through a common goal and rationale that seeks dialectic synthesis between divergent constructions while forming mutual, catalyzing impetuses between varying facets. In essence, the integration of varying technologies in conjunction, connected to real world scenarios and a guiding epistemic framework cultivates effective cross-pollination of ideas and modes through communicative and participatory interaction. As such it also provides greater ease in crosschecking between a multitude of divergent modes playing upon urban design and community development. Since current digital technologies aid in data collection and the synthesis of information, varying factors can be more easily and collectively identified, analyzed, and then simultaneously used in subsequent design configurations. It inherently fosters the not fully realized potential to collectively overlay or montage complex patterns and thoughts seamlessly and to thus subsequently merge a multitude of corresponding design configurations simultaneously within an ongoing, usable database. As a result, the pedagogical process reveals richly textured sociocultural fabrics and thus produces distinct amplifications in complexity and attentive management of diverse issues, while also generating significant narratives and themes for fostering creative and integrative solutions. As a model for urban community and social development, critical environmentalism is further supported the integrative use of digital technologies as an effective means and management for essential, communicative interchange of knowledge and thus rapprochement between divergent modes-of-thought, promoting critical, productive interaction with others in the (co)constructive processes of our life-space.

title	Adaptive Generative Patterns: design and construction of Prague Biennale pavilion
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	This paper describes an experimental practice-based research project that considered design process, implementation and construction of a pavilion built to be part of the Performative Space section of the International Biennale of Contemporary Art, Prague 2005. The project was conceptualized as a time-bound performative situation with a parasite-like relationship to its host environment. Its design has emerged through an innovative iterative process that utilized digital simulative and procedural techniques and was formed in response to place-specific behavioral challenges. This paper presents the project as an in-depth case-study of digital methods in design, mass customization and unified methods of production. In particular, it considers the use of Voronoi patterns for production of structural elements providing detail on programming and construction techniques in relationship to design aspirations and practical constraints.

summary	The work presented here discusses an ongoing research in constructing a knowledge representation system founded on CAAD document repositories and investigating the network of concepts constructed by CAAD research. The approach does not rely on conceptual models or theories about CAAD research, rather a formal semantics amenable to decidable reasoning on the corpus of research in CAAD. A web-based demonstration application is illustrated in the paper in which we discuss two propositions about CAAD research discovered in the process of our investigations.

doi	https://doi.org/10.52842/conf.ecaade.2006.770
summary	This paper explains the parameters and methodology at the heart of an ongoing research project that seeks to verify whether one can trace back the genesis of any given artefact or work of art by means of computer-aided modeling. In its endeavour our research team Computer Assisted Design Research Group (GRCAO) aims to initiate and propose novel methods of modeling design processes. This approach is exemplified by a case study dealing with rose tracery designs adorning Gothic cathedrals of 12th and 13th Century Île-de-France. A computerized model reenacting their design process was developed along with an interface enabling the translation of the designer’s intentions into a virtual design space. The stated goal of this research project is to evaluate empirically to what extent our modeling strategies can grasp a given artefact as a logical and articulate ensemble. Furthermore, we seek eventually to determine whether this kind of software programme would prove an adequate tool in the development of the architectural designer’s cognitive abilities.

title	A framework towards designing responsive public information systems
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 767-782
summary	"Evolving effective responsive systems, and creating a credible interface between the work and the user, requires an awareness of many different types of user, contexts and functions as well as the phenomenological aspects of social and environmental conditions." (Bullivant, 2006). Responsive design and interactive architecture operates at the intersection of Architecture, Arts, Technology, Media Arts, HCI and Interaction Design in a physical context suggesting ways in which the existing physical environments can be augmented and extended adding a greater level of depth, meaning and engagement with the world around us. Through a series of case studies, this paper explores a number of principles which may be applied to the design of responsive environments of which public information systems form part. Divided into three main sections, the paper first explains how responsive environments have addressed the application of public information systems, secondly, through a series of case studies, precedents are highlighted which lead to development of principles for developing designs for responsive environments. The third section discusses and elaborates on these principles which have been developed based upon our own interpretations and grouping of precedents and approaches towards interaction design. This paper contributes towards the field of responsive environments and interactive architecture through an analysis of case studies to infer a framework from which responsive environments may be created and developed.

title	A Framework of Haptic Design Parameters for Architects: Sensory Paradox Between Content and Representation
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. 685-700.
summary	Architects‚Äîlike other designers‚Äîtend to think, know and work in a visual way. In design research, this way of knowing and working is highly valued as paramount to design expertise (Cross 1982, 2006). In case of architecture, however, it is not only a particular strength, but may as well be regarded as a serious weakness. The absence of non-visual features in traditional architectural spatial representations indicates how these are disregarded as important elements in conceiving space (Dischinger 2006). This bias towards vision, and the suppression of other senses‚Äîin the way architecture is conceived, taught and critiqued‚Äîresults in a disappearance of sensory qualities (Pallasmaa 2005). Nevertheless, if architects design with more attention to non visual senses, they are able to contribute to more inclusive environments. Indeed if an environment offers a range of sensory triggers, people with different sensory capacities are able to navigate and enjoy it. Rather than implementing as many sensory triggers as possible, the intention is to make buildings and spaces accessible and enjoyable for more people, in line with the objective of inclusive design (Clarkson et al. 2007), also called Design for All or Universal Design (Ostroff 2001). Within this overall objective, the aim of our study is to develop haptic design parameters that support architects during design in paying more attention to the role of haptics, i.e. the sense of touch, in the built environment by informing them about the haptic implications of their design decisions. In the context of our study, haptic design parameters are defined as variables that can be decided upon by designers throughout the design process, and the value of which determines the haptic characteristics of the resulting design. These characteristics are based on the expertise of people who are congenitally blind, as they are more attentive to non visual information, and of professional caregivers working with them. The parameters do not intend to be prescriptive, nor to impose a particular method. Instead they seek to facilitate a more inclusive design attitude by informing designers and helping them to think differently. As the insights from the empirical studies with people born blind and caregivers have been reported elsewhere (Authors 2010), this paper starts by outlining the haptic design parameters resulting from them. Following the classification of haptics into active, dynamic and passive touch, the built environment unfolds into surfaces that can act as ‚Äúmovement‚Äù, ‚Äúguiding‚Äù and/or ‚Äúrest‚Äù plane. Furthermore design techniques are suggested to check the haptic qualities during the design process. Subsequently, the paper reports on a focus group interview/workshop with professional architects to assess the usability of the haptic design parameters for design practice. The architects were then asked to try out the parameters in the context of a concrete design project. The reactions suggest that the participating architects immediately picked up the underlying idea of the parameters, and recognized their relevance in relation to the design project at stake, but that their representation confronts us with a sensory paradox: although the parameters question the impact of the visual in architectural design, they are meant to be used by designers, who are used to think, know and work in a visual way.

title	Multi-criteria evolutionary optimisation of building enveloped during conceptual stages of design
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 497–506
doi	https://doi.org/10.52842/conf.caadria.2012.497
summary	This paper focuses on using evolutionary algorithms during conceptual stages of design process for multi-criteria optimisation of building envelopes. An experiment is carried out in optimising a panelled building envelope. The design scenario for the experiment is based on the scenario described in Shea et al. (2006) for the building envelope of the Media Centre Building in Paris. However, in their research, the optimisation process only allowed panel configuration to be optimised. In this paper, the task is to approach the optimisation of the envelope of the same building, assuming it to be in the early phases of the design process. The space of possible solutions is therefore assumed to be much wider, and as a result both external building form and internal layout of functional activities are allowed to vary. The performance intent of the experiment remains the same as that of Shea et al. (2006), which was to maximise daylight and minimise afternoon direct sun hours in the building at certain specific locations.

title	Adapting Digital Technologies to Architectural Education Need
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	Adapting digital technologies to architecture school settings is a topic of universal interest. Properly construed, adapting digital technologies to architectural education emanates from philosophical underpinnings. For architectural programs, the scientific-artistic attribute notion can be a powerful reference for mapping program mission, goals, and curriculum. A program plan developed with scientific-artistic attributes of performance in mind can tap on the use of digital media from the perspective that the media has scientific-artistic characteristics itself. Implementation of digital technologies adaptation can be challenged, among other things, by scarcity in resources. This paper focuses on the role of digital equipment resources in adaptation. A case in point is the use of digital technologies at the Architecture and Environmental Design Studies (Arch/EDS) Program of Bowling Green State University. The study considered the utilization by the third and fourth year design studio students of the digital resources at the Center for Applied Technology, a College based, but University wide serving unit. The objective of the study was to build up a theoretical understanding of the adaptation problem and come up with strategy guidelines for adapting digital media resources to architectural education. A survey of students and interviews with the Center’s personnel were methods used to collect data. The study has placed the adaptation problem in a philosophical context, turned out a set of theoretical generalizations about digital utilization, and suggested strategy adaptive guidelines. Beyond facilitating adaptation specific to the Arch/EDS Program, the results of the study are bound to affect digital adaptation in a general sense.

title	Component Based Design and Digital Manufacturing - A DfM Model for Curved Surfaces Fabrication using Three Axis CNC Router
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 342-350
doi	https://doi.org/10.52842/conf.ecaade.2006.342
summary	Through the use of design for manufacturing (DfM) method and looking at the relations between its potential application in architectural production and its implementation using digital manufacturing technologies, we analyze building construction processes and explore, in more detail curved surface fabrication using two dimensional cutting and three dimensional milling processes. Afterwards a DfM model for curved surfaces fabrication using three-axis computer numerical control (CNC) router is proposed. The proposed DfM model relies fundamentally in two supporting factors; the implementation of design heuristics that integrates production knowledge and the availability of some design related to production evaluation metrics. Subsequently, we test and refine the model using structured design experiences. This was accomplished by capturing new design heuristics and detecting useful evaluation metrics for production. In the final part of the research, a refined DfM model was tested in a component design case study. The case study is based on producing a curved surface module on wood for an existing proprietary component based wall system. As a summary, we conceptualize from this top-down development approach to create a design for manufacturing model that integrates design and construction in architecture, based on three possible applications fields: Design processes improvement, building production process improvement, CAD-CAM tools development. Our purpose is to provide better foundational constructs and approaches for integrating design with manufacturing in architecture.

title	Designing with Machines: solving architectural layout planning problems by the use of a constraint programming language and scheduling algorithms
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	In 1845 Edgar Allan Poe wrote the poem “The Raven”, an act full of poetry, love, passion, mourning, melancholia and death. In his essay “The Theory of Composition” which was published in 1846 Poe proved that the poem is based on an accurate mathematical description. Not only in literature are structures present that are based on mathematics. In the work of famous musicians, artists or architects like Bach, Escher or Palladio it is evident that the beauty and clarity of their work as well as its traceability has often been reached through the use of intrinsic mathematic coherences. If suchlike structures could be described within architecture, their mathematical abstraction could supplement “The Theory of Composition” of a building. This research focuses on an approach to describe principles in architectural layout planning in the form of mathematical rules that will be executed by the use of a computer. Provided that “design” is in principle a combinatorial problem, i.e. a constraint-based search for an overall optimal solution of a design problem, an exemplary method will be described to solve problems in architectural layout planning. Two problem domains will be examined: the design of new buildings, as well as the revitalization of existing buildings. Mathematical and syntactical difficulties that arise from the attempt to extract rules that relate to the process of building design will be pointed out. To avoid conflicts relating to theoretical subtleness a customary approach has been chosen in this work which is adopted from Operations Research. In this approach design is a synonym for planning, which could be described as a systematic and methodical course of action for the analysis and solution of current or future problems. The planning task is defined as an analysis of a problem with the aim to prepare optimal decisions by the use of mathematical methods. The decision problem of a planning task is represented by an optimization model and the application of an efficient algorithm to aid finding one or more solutions to the problem. The basic principle underlying the approach presented herein is the understanding of design in terms of searching for solutions that fulfill specific criteria. This search will be executed by the use of a constraint programming language, which refers to mathematical as well as to integer and mixed integer programming. Examples of architectural layout problems will be presented that can be solved by the use of this programming paradigm. In addition to this, a second programming approach resulting from the domain of resource-allocation has been followed in this research. It will be demonstrated that it is as well possible, to aid architectural layout planning by the use of scheduling algorithms.

summary	Computer tools have been used by experts for a wide range of activities including design and planning, historical conservation, urban management, education, and marketing and promotion. However, the difficulty of using these tools has meant that they have only been used by experts and their benefits have not been available to the public when engaged in participative design exercises. This paper reviews the extent of computer tool usage within urban design and goes on to propose a new way of utilizing digital tools in order to involve non-experts. The work that is presented here takes the form of an experiment which compares the traditional participative design approach with one that employs a three-dimensional digital approach. The setting for the experiment is based on the design of student housing on the University of Bath campus in the United Kingdom. Findings from the experiment demonstrate that the digital toolkit that is proposed has considerable potential to aid the process of participatory design.

summary	Previous research has established virtual reality provides users with unique experience. However, litter is known how users interact with virtual reality enabled interfaces differently from other conventional interfaces and how user-system interaction with virtual reality contributes to usability. This paper proposes a theoretical frame work to better understand the usability and user experience of a virtual reality enabled interface from an integrated view of information science and human-computer interaction. Based on the framework, an experimental case study was conducted. The context was taken from an Internet based virtual reality system where viewers are asked to evaluate design of furniture. In this paper, an overview of the research method and analysis is presented.

title	A Collaborative Digital Design Workshop: an ANN-based paradigm approach
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	This paper relies on observation and analysis an internationally digital design exchange activity, “The FCU & Bartlett School of Architecture, university college London (UCL) digital architecture workshop” to propose an educational model based on the artificial neural network (ANN). We expect that the results of this work can lead to the establishment of a scoring mechanism that can "adapt" to the difficulty of assigned problems and assess students' progress. An international technological exchange workshop based on the theme of digital design is helpful to attain an accelerated heightening in the quality and experience of education. This is going to be an educational trend and increasingly prevalent in the future. A successful educational curriculum in digital design relies on a concerted effort amongst curriculum framework, learning activities, and course content. While, an internationally exchange digital design workshop is different from traditional "semester-based" units of curriculums. The short-term educational models are required high degrees interaction and collaboration. On the other hand, artificial neural network system that is context aware in ill-defined and complex environments is highly adaptive. It can extract, interpret and use the context information and adapt its functions to obtain an optimal correspondence between “context change” and “desired goal” efficiently. Therefore, an ANN-based pedagogical mechanism is able to encourage students to select relatively difficult design problems and promote more design originality, interaction and collaboration.

summary	In this paper, we will discuss the system environment that supports management and conservation works for historical landscape and architecture. The proposed system enables both 3D map based spatial data management in urban scale and VR model based landscaping in street scale in one Web system. Moreover users can share their comments in those 3D spaces at any locations and any time. We set up this system for the historical City of Kanazawa. The system is gong to be assessed in the actual landscape planning project.

title	An Analysis of the Applications of Rapid Prototyping in Architecture
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	Rapid prototyping (RP) techniques are widely used within the design/manufacturing industry and are well established in manufacturing industry. These digital techniques offer quick and accurate prototypes with relatively low cost when we require exact likeness to a particular scale and detail. 3D modeling of buildings on CAD-systems in the AEC sector is now becoming more popular and becoming widely used practice as the higher efficiency of working with computers is being recognized. However the building of scaled physical representations is still performed manually, which generally requires a high amount of time. Complex post-modernist building forms are more faithfully and easily represented in a solid visualization form, than they could be using traditional model making methods. Using RP within the engineering community has given the users the possibility to communicate and visualize designs with greater ease with the clients and capture any error within the CAD design at an early stage of the project or product lifecycle. In this paper, the application of RP in architecture is reviewed and the possibilities of modeling architectural models are explored. A methodology of developing rapid prototypes with 3D CAD models using methods of solid freeform manufacturing in particular Fused Deposition Modeling (FDM) is presented and compared against traditional model making methods. An economical analysis is presented and discussed using a case study and the potential of applying RP techniques to architectural models is discussed.
