title	Planning of Environments for People with Physical Disabilities Using Computer Aided Design
source	Lund Institute of Technology, School of Architecture
summary	In the area of environment adaptations for people with physical disabilities, it is of vital importance that the design is optimized considering the human-environment interactions. All involved persons in such a planning process must be given sufficient support in understanding the information, so that everyone can participate actively. There is an apparent risk that discussions will be kept between experts, due to difficulties in understanding the complex and technical adaptation issues. This thesis investigates the use of computer-based tools for planning/designing environments for physically disabled people. A software prototype, and a method to use such a tool in the planning process, was developed and evaluated, based on the findings from six case studies of real planning situations. The case studies indicated that although such a tool would support the design, as well as the dialog between the participants, a certain level of technical and economical efficiency must be obtained. To facilitate the professional planner's work, an important issue is to maintain a large library of 3D objects. With the latest prototype implementation, it was found that such a planning tool can be produced, even when using consumer-oriented computers. One previous critical factor, interactive manipulation of 3D objects, can now be achieved if utilizing modern graphic cards with 3D acceleration. A usability test was performed to evaluate the prototype's basic operations, involving two groups of future users: five occupational therapist students, and four persons with major physical impairments. It was found that although the usability was satisfactory for the basic tasks, several items needed to be improved or added in future versions. It is important with an integrated support for manikins, in order to evaluate, e.g., wheelchair accessibility, reach ability, positioning of handrails, etc. This thesis reviews and compiles published anthropometrical and biomechanical data into a uniform segment-by-segment structure, in order to aid the design and modifications of manikins. The compilation was implemented as a spreadsheet document. An MRI investigation of the neck-shoulder region was performed on 20 healthy Scandinavian, female volunteers, measuring various musculoskeletal properties. These measurements can be used for further refinements of manikin specifications and biomechanical models.

title	Computational Specification of Building Requirements in theEarly Stages of Design
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	We have been exploring computational techniques to help building designers to specify design requirements during the early stages of design. In the past, little has been accomplished in this area either in terms of innovative computational technologies or the improvement of design performance.The prospect of improving design productivity and creating a seamless process between requirements specification and formal design are our primary motivations. This research has been conducted as partof a larger project entitled SEED (Software Environment to Support Early Phases in Building Design). SEED features an open-ended modular architecture, where each module provides support for a design activity that takes place in early design stages. Each module is supported by a database to store and retrieve information, as well as a user interface to support the interaction with designers. The module described in this paper, SEED-Pro (the architectural programming module of SEED), is a workingprototype for building design requirements specification. It can be used by other modules in SEED or by design systems in other domains, such as mechanical engineering, civil engineering, industrial designand electrical engineering. Our approach to SEED-Pro is divided into two phases: core, and support functionalities. The core functionalities operate in an interactive mode relying on a case-based approach to retrieve and adapt complex specification records to the problem at hand. The supportfunctionalities include the case-base, the data-base, and the standards processing environment for building specification tasks. Our findings indicate that SEED-Pro: (1) is a tool that structures the unstructured domain of design requirements; (2) enables the integration of design requirements with the rest of the design process, (3) leads to the creation of complex case-bases and (4) enables the observation of their performance in the context of real world design problems.

title	Classification of Precedents - A Hybrid Approach to Indexing and Retrieving Design Cases in SEED (a Software Environment for the Early Phases of Building Design)
source	CAADRIA ‘98 [Proceedings of The Third Conference on Computer Aided Architectural Design Research in Asia / ISBN 4-907662-009] Osaka (Japan) 22-24 April 1998, pp. 435-444
doi	https://doi.org/10.52842/conf.caadria.1998.435
summary	An efficient indexing of past solutions is crucial to case-based design (CBD) systems performing complex retrieval on large case-bases. This paper suggests a hybrid approach to the indexing and retrieval of design precedents. The suggested approach accounts for the issues of classification manifested in architectural discussions on type and CBD literature. The indexing scheme integrates description-logic based representation for classification and an object-based representation for precedents. The hybrid scheme constitutes a basis for the implementation of a generic case indexing and retrieval mechanism for SEED.

title	Informing Public Participation in Neighborhood ScalePlanning and Design
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	Neighborhood scale planning and design in many areas of the United States has been evolving toward a system of negotiated priorities and agreements. Common models include public workshops and design 'charrettes' which bring diverse stakeholders (citizens, land owners, developers, consultantsand public officials, for example) together to develop a mutually acceptable plan. Crucial to the quality and effectiveness of the outcome are decision support tools that help this diverse audience understand, communicate, collaborate and make decisions about complex and often emotional issuesof land use and design. Net Energy Communities (NEC), the project summarized in this paper, creates a suite of computer based tools for this purpose. NEC links three types of computer software — the spatial data manipulation, modeling and visualization capabilities of Geographic Information Systems (GIS), the illustration and information retrieval capabilities of multimedia relational databases and, the simulation and comparison capabilities of spreadsheet-based calculation models;into four tools — a site modeller, an elements of neighborhood database, a scenario modeller and ascenario calculator. This paper reports on the NEC project as an example of decision support tools for public participation using illustrations and examples from a 420 acre demonstration neighborhood design in progress for the City of Corvallis, Oregon, USA.

summary	Mesh segmentation has become an important and well-researched topic in computational geometry in recent years (Agathos et al. 2008). As a result, a number of new approaches have been developed that have led to innovations in a diverse set of problems in computer graphics (CG) (Sharmir 2008). Specifically, a range of effective methods for the division of a mesh have recently been proposed, including by K-means (Shlafman et al. 2002), graph cuts (Golovinskiy and Funkhouser 2008; Katz and Tal 2003), hierarchical clustering (Garland et al. 2001; Gelfand and Guibas 2004; Golovinskiy and Funkhouser 2008), primitive fitting (Athene et al. 2004), random walks (Lai et al.), core extraction (Katz et al.) tubular multi-scale analysis (Mortara et al. 2004), spectral clustering (Liu and Zhang 2004), and critical point analysis (Lin et al. 20070, all of which depend upon a weighted graph representation, typically the dual of a given mesh (Sharmir 2008). While these approaches have been proven effective within the narrowly defined domains of application for which they have been developed (Chen 2009), they have not been brought to bear on wider classes of problems in fields outside of CG, specifically on problems relevant to generative architectural design. Given the widespread use of meshes and the utility of segmentation in GAD, by surveying the relevant and recently matured approaches to mesh segmentation in CG that share a common representation of the mesh dual, this paper identifies and takes steps to address a heretofore unrealized transfer of technology that would resolve a missed opportunity for both subject areas. Meshes are often employed by architectural designers for purposes that are distinct from and present a unique set of requirements in relation to similar applications that have enjoyed more focused study in computer science. This paper presents a survey of similar applications, including thin-sheet fabrication (Mitani and Suzuki 2004), rendering optimization (Garland et al. 2001), 3D mesh compression (Taubin et al. 1998), morphin (Shapira et al. 2008) and mesh simplification (Kalvin and Taylor 1996), and distinguish the requirements of these applications from those presented by GAD, including non-refinement in advance of the constraining of mesh geometry to planar-quad faces, and the ability to address a diversity of mesh features that may or may not be preserved. Following this survey of existing approaches and unmet needs, the authors assert that if a generalized framework for working with graph representations of meshes is developed, allowing for the interactive adjustment of edge weights, then the recent developments in mesh segmentation may be better brought to bear on GAD problems. This paper presents work toward the development of just such a framework, implemented as a plug-in for the visual programming environment Grasshopper.

title	Digital Architecture in CAD studio and Internet-based competition
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	Architectural design has been changing because of the vast and creative use of computer in different ways. From the viewpoint of designing itself, computer has been used as drawing tools in the latter phase of design (Mitchell 1977; Coyne et al. 1990), presentation and simulation tools in the middle phase (Liu and Bai 2000), and even critical media which triggers creative thinking in the very early phase (Maher et al. 2000; Liu 1999; Won 1999). All the various roles that computer can play have been adopted in a number of professional design corporations and so-called computer-aided design (CAD) studio in schools worldwide (Kvan 1997, 2000; Cheng 1998). The processes and outcomes of design have been continuously developing to capture the movement of the computer age. However, from the viewpoint of social-cultural theories of architecture, the evolvement of design cannot be achieved solely by designers or design processes. Any new idea of design can be accepted socially, culturally and historically only under one condition: The design outcomes could be reviewed and appreciated by critics in the field at the time of its production (Csikszentmihalyi 1986, 1988; Schon and Wiggins 1992; Liu 2000). In other words, aspects of design production (by designers in different design processes) are as critical as those of design appreciation (by critics in different review processes) in the observation of the future trends of architecture.Nevertheless, in the field of architectural design with computer and Internet, that is, so-called computer-aided design computer-mediated design, or internet-based design, most existing studies pay more attentions to producing design in design processes as mentioned above. Relatively few studies focus on how critics act and how they interact with designers in the review processes. Therefore, this study intends to investigate some evolving phenomena of the interaction between design production and appreciation in the environment of computer and Internet.This paper takes a CAD studio and an Internet-based competition as examples. The CAD studio includes 7 master's students and 2 critics, all from the same countries. The Internet-based competition, held in year 2000, includes 206 designers from 43 counties and 26 critics from 11 countries. 3 students and the 2 critics in the CAD studio are the competition participating designers and critics respectively. The methodological steps are as follows: 1. A qualitative analysis: observation and interview of the 3 participants and 2 reviewers who join both the CAD studio and the competition. The 4 analytical criteria are the kinds of presenting media, the kinds of supportive media (such as verbal and gesture/facial data), stages of the review processes, and interaction between the designer and critics. The behavioral data are acquired by recording the design presentation and dialogue within 3 months. 2. A quantitative analysis: statistical analysis of the detailed reviewing data in the CAD studio and the competition. The four 4 analytical factors are the reviewing time, the number of reviewing of the same project, the comparison between different projects, and grades/comments. 3. Both the qualitative and quantitative data are cross analyzed and discussed, based on the theories of design thinking, design production/appreciation, and the appreciative system (Goodman 1978, 1984).The result of this study indicates that the interaction between design production and appreciation during the review processes could differ significantly. The review processes could be either linear or cyclic due to the influences from the kinds of media, the environmental discrepancies between studio and Internet, as well as cognitive thinking/memory capacity. The design production and appreciation seem to be more linear in CAD studio whereas more cyclic in the Internet environment. This distinction coincides with the complementary observations of designing as a linear process (Jones 1970; Simon 1981) or a cyclic movement (Schon and Wiggins 1992). Some phenomena during the two processes are also illustrated in detail in this paper.This study is merely a starting point of the research in design production and appreciation in the computer and network age. The future direction of investigation is to establish a theoretical model for the interaction between design production and appreciation based on current findings. The model is expected to conduct using revised protocol analysis and interviews. The other future research is to explore how design computing creativity emerge from the process of producing and appreciating.

title	Java collaborative interface for architectural simulations A case study on wooden ceilings of Krakow
source	International Conference On Conservation - Krakow 2000, 23-24 November 1998, Krakow, Poland
summary	Concern for the architectural and urban preservation problems has been considerably increasing in the past decades, and with it the necessity to investigate the consequences and opportunities opened for the conservation discipline by the development of computer-based systems. Architectural interventions on historical edifices or in preserved urban fabric face conservationists and architects with specific problems related to the handling and exchange of a variety of historical documents and representations. The recent development of information technologies offers opportunities to favour a better access to such data, as well as means to represent architectural hypothesis or design. Developing applications for the Internet also introduces a greater capacity to exchange experiences or ideas and to invest on low-cost collaborative working platforms. In the field of the architectural heritage, our research addresses two problems: historical data and documentation of the edifice, methods of representation (knowledge modelling and visualisation) of the edifice. This research is connected with the ARKIW POLONIUM co-operation program that links the MAP-GAMSAU CNRS laboratory (Marseilles, France) and the Institute HAiKZ of Kraków's Faculty of Architecture. The ARKIW programme deals with questions related to the use of information technologies in the recording, protection and studying of the architectural heritage. Case studies are chosen in order to experience and validate a technical platform dedicated to the formalisation and exchange of knowledge related to the architectural heritage (architectural data management, representation and simulation tools, survey methods, ...). A special focus is put on the evolution of the urban fabric and on the simulation of reconstructional hypothesis. Our contribution will introduce current ARKIW internet applications and experiences: The ARPENTEUR architectural survey experiment on Wie¿a Ratuszowa (a photogrammetrical survey based on an architectural model). A Gothic and Renaissance reconstruction of the Ratusz Krakowski using a commercial modelisation and animation software (MAYA). The SOL on line documentation interface for Kraków's Rynek G_ówny. Internet analytical approach in the presentation of morphological informations about Kraków's Kramy Bogate Rynku Krakowskiego. Object-Orientation approach in the modelling of the architectural corpus. The VALIDEUR and HUBLOT Virtual Reality modellers for the simulation and representation of reconstructional hypothesis and corpus analysis.

title	Prototypical Laboratory Design to Support Learning and Teaching
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	Collaboration between designers and scientists is an unusual combination to undertake the prototypical design of a teaching laboratory funded by Howard Hughes Medical Institute. The zoologists are developing a cooperative learning and interactive teaching pedagogy to make learningscience a process of critical inquiry and discovery. The industrial and interior designers are paying attention to the design issues of function and environmental support for teaching and doing the work required in a three-hour, hands-on beginning science learning space. Using both qualitative andquantitative research methods, the designers are able to determine a framework for making design decisions in prototypical beginning science environments. This framework is being developed as a guideline for designing similar environments at other institutions of higher learning. Videotape analysis precedes the research to uncover the underlying problems of the existing space and to formulate the questions for the research. Elements of a case study and an evaluative study integratewith the design process to form the basis of an intensive investigation of design issues for a beginning science teaching laboratory. Using two pretests as a baseline, the posttest data evaluates the success orfailure of the prototypical design. Both the pretests and the posttest evaluate the physical attributes of the old and new learning environment related to a beginning laboratory course in Zoology at Arizona State University.

title	Evaluating Office Buildings with MOLCA(Model for Office Life Cycle Assessment)
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	MOLCA (Model for Office Life Cycle Assessment) is a project that aims to develop a tool that enables designers and builders to evaluate the environmental impact of their designs (of office buildings) from a environmental point of view. The model used is based on guidelinesgiven by ISO 14000, using the so-called Life Cycle Assessment (LCA) method. The MOLCA project started in 1997 and will be finished in 2001 resulting in the aforementioned tool. MOLCA is a module within broader research conducted at the Eindhoven University of Technology aiming to reduce design risks to a minimum in the early design stages.Since the MOLCA project started two major case-studies have been carried out. One into the difference in environmental load caused by using concrete and steel roof systems respectively and the role of recycling. The second study focused on biases in LCA data and how to handle them. For the simulations a computer-model named SimaPro was used, using the world-wide accepted method developed by CML (Centre for the Environment, Leiden, the Netherlands). With this model different life-cycle scenarios were studied and evaluated. Based on those two case studies and a third one into an office area, a first model has been developed.Bottle-neck in this field of study is estimating average recycling and re-use percentages of the total flow of material waste in the building sector and collecting reliable process data. Another problem within LCA studies is estimating the reliability of the input data and modelling uncertainties. All these topics will be subject of further analysis.

title	An Experimental Design System for the Very Early Design Stage
source	Timmermans (ed.) Proceedings of the 4th Conference on Design and Decision Support Systems in Architecture and Urban Planning, Maastricht
summary	The concepts of the experimental design system that are discussed are feature modeling and geometrical constraints. The main technique for creating the user environment is Virtual Reality. Feature modeling forms the basis for managing the design data. To start with, data storage is implemented in a Relational Data Base Management System. Along with this a (traditional) interface is developed for managing the data. Data management consists of feature type creation and feature type instancing. Features are used to define building elements, their relationships and additional constraints. Apart from the design data, geometrical data are stored. Possible design solutions can be limited using geometrical constraints. Specifying connection types between building elements result in a set of solutions for the position of the bounding boxes of the building elements in space.

title	A Research on Housing in Ankara-Turkey
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	The subject of this research contains an opinionnaire study and its results obtained from 30 houses in Ankara-TURKEY in which the people have middle and upper middle income so as to identify their favourites and criticsm about housing, regarding to their both houses and environment as well as tomake the definition of ideal houses and environment. Totally 30 subjects of which 21 are female and 9 are male which represent middle and upper middle incomed people. The average age of the subjects whose age range vary between 21 and 70 is 41. In the study, firstly, the opinionnaire questions were prepared and the housing in which the middle and upper middle incomed people live were determined as socio-economic level to be examined. Next permission and time reservation were requested fromthe owner's of housing to implement the study. During the times which have been determined by the subjects, the following procedure has been followed reading of the opinionnaire forms by myself and recording of responses of the subjects exactly, drawing of reliefs and plans of house, taking pictures of outer views and surroundings of housings. Tendencies of users' against various conditions have been transformed into numerical values from 1 to 7 in a scale with 7 column. In the light of above information; Considering the country conditions it was observed that these housing were excessivelylarge and were built for ostentation purposes, not for functional purposes. Usefulness, that is to say, design of house is in the bottom of the criteria list and it is not an important factor to choose the house, form another part of interesting findings of this study. Another significant result has been observed due to users desire about their house. Although the rising of design which was in 6th rank among the reasons to prefer a house was not an effective criteria on users' attitudes merely to have ahouse, this criteria was the 1st rank (87 %) among reasons due to the advantages that were provided for the users with respected to design and functionality as a result of meticulous studies of architects.Users' criticisms on their vicinity have shown variations according to their sexes.As a result of this research that were initiated to define the ideal house and environment concepts; interesting and detailed data about users' tendencies in the scope of both house and settling are available in "Findings" part of this study. Rising of desing criteria which was the 6 th rank amongcriteria's to choose a house, to 1st rank has brought the following conclusion: since the users are not able to act consciously due to the consideration of the properly owing action much more important,the main duty here is performed by the planner. Hence, starting from the assumption that users living in housings are extremely sensitive to their houses and especially environments, provision of public participation via this kind of opinionnaire studies while creating new environments, may contribute to create such environments in which people can live.

title	Conjoint Analysis and Virtual Reality - A Review
source	Timmermans (ed.), 4 Ih Design and Decision Support Systems in Architecture and Urban Planning Conference.
summary	This paper describes a review of an ongoing research project which aims to develop a conjoint analysis and virtual reality (CA&VR) system as part of a design information system in virtual reality. The research project aims to develop a design system that can be used for interactive design and evaluation of design alternatives. A virtual environment model and dynamic virtual objects representing the different design aspects of interest can present a design. The different design aspects are called attributes. Each attribute level is a different state of the concerned virtual object. In the case of a virtual walk through a building design, the system can be viewed as a visual simulation of the environment. The CA&VR system has the potential advantage that individuals' preferences can be measured in designed hypothetical choice situations. As part of the ongoing research project, principles underlying the CA&VR system will be illustrated by simple examples. The status of this research project, both in retrospect and in prospect will be described.

title	Visual Communication in Urban Planning and Urban Design
source	Working Paper 2; Centre for Advanced Spatial Analysis Working Papers; London; June 1998
summary	This Case Study documents the current status of visual communication in urban design and planning. Visual communication is examined through discussion of standalone and network media, specifically concentrating on visualisation on the World Wide Web (WWW). First, we examine the use of Solid and Geometric Modelling for visualising urban planning and urban design. This report documents and compares examples of the use of Virtual Reality Modelling Language (VRML) and proprietary WWW based Virtual Reality modelling software. Examples include the modelling of Bath and Glasgow using both VRML 1.0 and 2.0. The use of Virtual Worlds and their role in visualising urban form within multi-user environments is reviewed. The use of Virtual Worlds is developed into a study of the possibilities and limitations of Virtual Internet Design Arena's (ViDA's), an initiative undertaken at the Centre for Advanced Spatial Analysis, University College London. The use of Virtual Worlds and their development towards ViDA's is seen as one of the most important developments in visual communication for urban planning and urban design since the development plan. Secondly, the role of photorealistic media in the process of communicating plans is examined. The process of creating photorealistic media is documented, and examples of the Virtual Streetscape and Wired Whitehall Virtual Urban Interface System are provided. The conclusion is that, although the use of photo-realistic media on the WWW provides a way to visually communicate planning information, its use is limited. The merging of photorealistic media and solid geometric modelling in the creation of Augmented Reality is reviewed. Augmented Reality is seen to provide an important step forward in the ability quickly and easily to visualise urban planning and urban design information. Third, the role of visual communication of planning data through GIS is examined in terms of desktop, three dimensional, and Internet based GIS. The evolution to Internet GIS is seen as a critical component in the development of virtual cities that will allow urban planners and urban designers to visualise and model the complexity of the built environment in networked virtual reality. Finally, a viewpoint is put forward of the Virtual City, linking Internet GIS with photorealistic multi-user Virtual Worlds. At present there are constraints on how far virtual cities can be developed, but a view is provided on how these networked virtual worlds are developing to aid visual communication in urban planning and urban design.

summary	The use of computers in the analysis of architectural structures has at present become indispensable and fairly routine. Researchers & professionals in architecture and engineering have taken advantage of current computer technology to develop richer and more comprehensive interactive interfaces in systems designed to analyse structural behaviour. This paper discusses a research project which attempts to further enrich such computer interfaces by embodying emotion or mood (affective) components into them and assessing the effects of incorporating these into multimodal learning modules for students of architecture at the University of Hong Kong. Computer structural analysis is most often used to determine the final state of a structure after full loading, but can also be used very ably to depict the time-history behaviour of a structure. The time-dependent nature of this process of behaviour provides an excellent opportunity to incorporate emotion cues for added emphasis and reinforcement. Studying time-history behaviour of structures is a vital part of classroom learning in structures and this why such emotion cues can have significant impact in such an environment. This is in contrast to the confines of professional engineering practices where these cues may not be as useful or desirable because oftentimes intermediate time history data is bypassed as a blackbox and focus is placed primarily on bottomline analysis results. The paper will discuss the fundamental basis for the establishment of emotional cues in this project as well as it's implementation-which consists mainly of two parts. The first involves 'personifying' the structure by putting in place a structure monitoring system analogous to human vital signs. The second involves setting up a 'ladder' of emotion states (which vary from feelings of serenity to those of extreme anxiety) mapped to the various states of a structures stability or condition. The paper will further elaborate on how this is achieved through the use of percussion, musical motifs, and chord progression in resonance with relevant graphical animations. Initially in this project, emotion cues were used to reinforce two structural behaviour tutoring systems developed by this author (3D Catenary Stuctures module & Plastic Behaviour of Semi-rigid Steel Frames module). These modules were ideal for implementing these cues because both depicted nonlinear structural behaviour in a mainly time-history oriented presentation. A brief demonstration of the actual learning modules used in the project study will also be presented together with a discussion of the assessment of it's effectiveness in actual classroom teaching.

title	The Grid Sketcher: An AutoCAD Based Tool for Conceptual Design Processes

summary	Sketching with pencil and paper is reminiscent of the varied, rich, and loosely defined formal processes associated with conceptual design. Architects actively engage such creative paradigms in their exploration and development of conceptual design solutions. The Grid Sketcher, as a conceptual sketching tool, presents one possible computer implementation for enhancing and supporting these processes. It effectively demonstrates the facility with which current technology and the computing environment can enhance and simulate sketching intents and expectations. One pervasive and troubling undercurrent, however, is the conceptual barrier between the variable processes of human thought and those indigenous to computing. Typically with respect to design, the position taken is that the two are virtually void of any fundamental commonality. A designer’s thoughts are intuitive, at times irrational, and rarely follow consistently identifiable patterns. Conversely, computing requires predictability in just these endeavors. Computing is strictly an algorithmic process while thought is not always so predictable. Given these dichotomous relationships, the computing environment, as commonly defined, cannot reasonably expect to mimic the typically human domain of creative design. In this context, this thesis accentuates the computer’s role as a form generator as opposed to a form evaluator. The computer, under the influence of certain contextual parameters can, however, provide the designer with a rich and elegant set of forms that respond through algorithmics to the designer’s creative intents. The software presented in this thesis is written in AutoLISP and exploits AutoCAD’s capacious 3D environment. Designs and productions respond to a bounded framework where user selected parametric variables of size, scale, proportion, and proximity, all which reflect contextual issues, determine the characteristics of a unit form. Designer selected growth algorithms then arbitrate the spatial relationships between the unit forms and their propagation through the developing design. While the Sketcher implements only the GRID as an organizational discipline, many other paradigms are possible. Within this grid structure a robust set of editing features, supported by the computer’s inherent speed, allows the designer to analyze successive productions while refining ever more complex solutions. Through creative manipulation of these algorithmic structures ideas eventually coalesce to formalize images that represent a given design problem’s solution set.

title	Conceptual Structural Design Through Knowledge Hierarchies
source	Carnegie Mellon University, Department of Civil and Environmental Engineering, Pittsburgh
summary	Computer support for conceptual design still lags behind software available for analysis and detailed design. The Software Environment to Support the Early Phases in Building Design (SEED) project has the goal of providing design generation and exploration capabilities to aid in the conceptual design of buildings, from architectural programming and layout to enclosure design and structural configuration. The current work presents a component of the efforts of the SEED-Config Structure group in providing computer support for conceptual structural design. The Building Entity and Technology (BENT) approach models data about building elements in a general, hierarchical form, where design evolution is represented by the growing specificity of the design description. Two methods of system-supported design generation are provided: case-based reasoning and application of knowledge rules. The knowledge rules, termed technologies, and how they are specified and used are the primary focus of this thesis. In the BENT approach, conceptual structural engineering knowledge is modularized into technology nodes arranged in a directed 'AND/OR' graph, where OR nodes represent alternative design decisions and AND nodes represent problem decomposition. In addition, nodes in the graph may also be specified as having AND/OR incoming arcs thus reducing the duplication of nodes and enhancing the representational power of the approach. In order to facilitate the incorporation of new knowledge into the system, and verify and/or change the knowledge already in the system, the data model and the interface allow for dynamic creation, browsing, and editing of technology nodes. Design generation through the use of the knowledge hierarchy involves the conditional application of nodes according to the design context as represented by the building element(s) under consideration. Each application of a technology node expands the design of building elements by increasing the detail of the design description or by decomposing the elements into less abstract components. In addition, support for simultaneous design of multiple elements and for iteration control are also provided. An important feature of the BENT approach is that the generative knowledge (i.e., the technology hierarchy) is detached from the information repository (i.e., the database of entities which make up the building). This allows the technology hierarchies to be used in a modular fashion from building problem to building problem.

title	A methodological approach to object modelling in the architectural designprocess
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	The paper describes a first prototype constructed in search for a central object model. It presents all possible data, concepts and operations concerning the architectural design process in the early phases.A central model of the process of design is essential: going from one design phase into another, the model describes geometrical shapes, abstract concepts like space and activity, concrete physical building elements and the basic operations all these entities undertake. Emphasis is put on combining all these different viewpoints, thus enabling the designer to use a broad range of design strategies. The aim is to help him and not steer or even hamper his creative process. Information necessary toassist the user of the system concerning energy calculation, stability checks etc can be extracted. By means of appropriate interfaces not only those tests built on top of the system but also existing software packages can make use of the model’s object structure. The implemented object model is one of the cornerstones of the IDEA+ project, aiming to provide an Integrated Design Environment for Architecture.

title	CAAD System with Integrated Quantity Surveying, Energy Calculation, and LCA
source	Proceedings: Green Building Challenge 98, Vancouver, Canada. Vol. 2, 68 - 75
summary	In the framework of the German LEGOE project, an integrated tool is developed for computer aided architectural design (CAAD), quantity surveying (catalogue of building elements), life cycle cost calculation and estimation (construction and refurbishment), direct energy consumption (heating, hot-water, electri-city) and environmental impact assessment (mass flows and effect oriented evaluation). During the design process the architect works in his usual CAAD environment with building elements (e.g. one m2 of outer wall) which in turn are composed of detailed construction specifications, energy and mass flow coefficients and cost data. These elements are part of an independent catalogue of elements with all their relevant data. The different application programs use the same basic data and write the specific results into a project-specific database called a PDB which allows the comparison of these data to reference data from other projects. Evaluation and visualisation programs refer to the PDB only.
