title	The BAS*CAAD Information System for Design principles, Implementation, and a Design Scenario
source	Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 149-164
summary	The objectives of the BAS-CAAD-project are to investigate into theories and methods for computer aided architectural design, with emphasis on requirements of early stages of the design process. Information systems can be characterised as static or dynamic concerning the definition of classes in the model schema, and concerning classification of model objects. The paper presents the BAS-CAAD system, a prototype software that implements the conceptually most important features of a dynamic information system for design. The BAS-CAAD information system is built on a generic ontological framework. The system allows a free combination of attributes, supporting the incremental way that knowledge is built up during design. It provides a generic library structure that allows definition of objects classes in different levels of generalisation that may originate from international standards or the individual designer. For example, in the construction context, it allows modelling of buildings and their parts, as well as user organisations and user activities. The function of the system is illustrated in two scenarios.

title	Digital Environments for Learning and Collaboration Architecture, Communication, Creativity, Media and Design Process
source	Media and Design Process [ACADIA ‘99 / ISBN 1-880250-08-X] Salt Lake City 29-31 October 1999, pp. 40-52
doi	https://doi.org/10.52842/conf.acadia.1999.040
summary	Digital networks are gaining importance as environments for learning and creative collaboration. Technical achievements, software enhancements, and a growing number of applicable principles make it possible to compile complex environments that satisfy many aspects necessary for creative collaboration. This paper focuses on three issues: the architecture of collaborative environments, communication in these environments and the processes inherent to creative collaboration. The information architecture of digital environments looks different from physical architecture, mainly because the material that it is made out of is information and not stone, wood or metal and the goal is to pro-vide appropriate paths and views to information. Nonetheless, many analogies can be drawn between information architecture and physical architecture, including the need for useability, aesthetics, and consistency. To communicate is important for creative collaboration. Digital networks request and enable new strategies for communicating. Regarding the collaborative creative process we have been able to detect principles and features that enhance this process, but there are still many unanswered questions. For example, the environment can enable and improve the frequency of surprise and coincidence, two factors that often play decisive roles in the creative processes but cannot be planned for in advance. Freedom and transparency within the environment are other important factors that foster creative collaboration. The following findings are based on numerous courses, which we have taught using networked environments and some associated, research projects that helped to verify their applicability for architectural practice.

summary	This paper introduces the commonality between diversity in the biological world and diversity in artifact design. It proposes a computational model of design development based on the analogy with the phenomena and principles of developmental biology. The model is feature based and is capable of varying design in logic, geometry, attribute and phase. Examples demonstrate this biological analogy and its benefits for design development.

title	Knowledge-Aided Design System for Intelligent Building Design
source	CAADRIA '99 [Proceedings of The Fourth Conference on Computer Aided Architectural Design Research in Asia / ISBN 7-5439-1233-3] Shanghai (China) 5-7 May 1999, pp. 305-312
doi	https://doi.org/10.52842/conf.caadria.1999.305
summary	In the age of information technology, architectural design problems become increasingly complex, the finding of optimal solutions has become more difficult and obscure. Computer-aided design techniques have been applied to solve these ill-structured design problems; however, most of these applications have been used for graphical automation. Design improvement in quality has not been achieved using traditional computer programs. To handle the critical design decision problems, design systems need to be structured based on theoretical problem solving models. This would enable the design system to handle the problem solving design knowledge as well as the various technological aspects and geometrical representations. A theoretical model, knowledge-aided design, is proposed. Knowledge-aided design is a conceptual and theoretical model based on fundamental principles of design. It provides a problem-solving environment and a procedure for knowledge-based computer-aided architectural design based on cognitive science and artificial intelligence techniques. As a partial implementation of the theoretical model, the development of knowledge-aided design system for intelligent building design is described.

summary	Information is everywhere. We are flooded by information and one can observe peoples problems handling the amount of information. The relational table as the mean to present information as well as simple html pages are having their obvious depts. Therefore, people are looking into three-dimensional representations and entire virtual environments to visualize data contents. Within this papers it is proposed to visualize information and information structures in a dynamic fashion. Therefore, we will have a look at some principles of dynamic representations as well as the metaphors and methods used to enables dynamic representations. With Autonomous Objects in Sculptor and inforMotion two examples are implemented in our research projects using dynamic data visualization.

title	Developing an Algorithm for Topological Transformation
source	SIGraDi’2000 - Construindo (n)o espacio digital (constructing the digital Space) [4th SIGRADI Conference Proceedings / ISBN 85-88027-02-X] Rio de Janeiro (Brazil) 25-28 september 2000, pp. 203-205
summary	This research intends to test the architectural application of Jean Piaget’s clinical observations, described in the book: The Child’s Conception of Space (Piaget, 1956), according to which topology is an ordering discipline, active in the human psyche. Earlier attempts, based on the principles of graph-theory, were able to cover only a narrow aspect of spatial relations, i.e. connectivity, and were mostly a-perceptional, visually mute. The “Spaceprint” method, explained and illustrated in co-author’s book: Thought Palaces (Magyar, 1999), through dimensional reduction, investigates volumetric, 3D characteristics and relationships with planar 2D configurations. These configurations, however, represent dual values: they are simultaneously the formal descriptors of both finite matter and (fragments of) infinite space. The so- called “Particular Spaceprint”, as a tool of design development in building, object, or urban scales, with the help of digital technology, could express - again simultaneously - qualities of an idea-gram and the visual, even tactile aspects of material reality. With topological surface-transformations, the “General Spaceprints”, these abstract yet visually active spatial formulas can be obtained.

title	The light and colour significance in urban environment perception
source	Simulation of Architectural Space - Color and Light, Methods and Effects [Proceedings of the 4rd European Architectural Endoscopy Association Conference / ISBN 3-86005-267-5] Dresden (Germany), 29 September - 1 October 1999, pp. 50-56
summary	My contribution deals with light and colour effects in wider dimensions of architecture. It analyses their significance in urban environment perception from the application aspect of progressive tools of its forming and creative completion, i.e. the perceptual homomorphous iconic simulations in laboratory conditions. The work focuses on questions of light and colour perception, showing several principles and phenomena valid in visual perception systems. The structure of the perceived picture is interpreted in its four components: colour, motion, form and spaciousness. Each of the components is shown with relevant biological reactions and their reflections in subjective perception processes. The selected image examples document some manifestations of urbanistic structures and spaces experience transformation in natural and artificial lighting conditions. The emphasis of my contribution lies on some demonstrations from the laboratory experiment in investigating the illumination and colour influence on the architectural design quality, and on examples of alternative methods of visual interpretation on endoscopic modelling simulation outputs. The conclusion of my work formulates some knowledge and statement of objective colour and light modelling simulation assets in architectural design quality.

title	An Epistemological and Systems Approach to Digital Technology Integration in Architectural Curriculum
source	Media and Design Process [ACADIA ‘99 / ISBN 1-880250-08-X] Salt Lake City 29-31 October 1999, pp. 16-26
doi	https://doi.org/10.52842/conf.acadia.1999.016
summary	Architectural institutions around the world have been faced with the question of digital technology integration for the last one decade. Numerous attempts have been made by those institutions to utilize and harness the new technology by trial and error methods. Although much has been said and done about the computer as a tool and a medium, there is a great paucity of well-considered and holistic theoretical frameworks that have been successfully applied in architectural curricula. The emergence of digital technology as an environment and as an overarching system has NOT been a much understood or acknowledged fact. This lack of systemic wisdom, in the digital technology integration process, is always punished by the system. In this paper, I intend to 1.) Outline the epistemological, philosophical, pedagogical and operational issues of digital technology integration efforts undertaken at Kansas State University. 2.) Meditate a systemic and holistic framework of principles, paradigms, proposals and strategies from a systems point of view that could be applied at other educational institutions. In contradistinction to the analytical, hierarchical and prosthetic approaches frequently adapted by the architectural institutions, I propose a systems approach and an ecological paradigm to understand and comprehensively integrate digital technology with architectural curricula. While many of the ideas brought under the framework may not be new, the framework itself is a new proposition. The framework draws heavily from Jean-François Lyotard’s postmodern pedagogical work, Deleuze and Guattari’s post-structural notions of “rhizome”, and Gregory Bateson’s expositions of ecological and systems approach.

title	Design Gaming, Designing Games - Learning Design through Game Playing and Game Making
source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 28-33
doi	https://doi.org/10.52842/conf.ecaade.2002.028
summary	This is an ongoing effort to make design learning fun and constructive. The process of designing, in many respects, is very similar to playing games: exploring possibilities under certain constraints. Since 1999, the “designing as game playing” concept has been used in architectural design studios and related courses in my institution. In the early years, preexisting games or games created by instructors were used. These games were played in a junior-year course that emphasized design decision-making and design collaborations. In recent two years, design game making has been used as a vehicle for senior-year student to strengthen their analytical skills. So far, students have developed games of Mario Botta, Le Corbusier (Villa Savoy), Aldolf Loos, Mies van der Rohe, and Richard Meier. Two more games are underdevelopment: the games of Isosaki and Tadao Ando. Some of these games have been used in freshman-year courses to introduce certain principles of form composition. Playing design games enables students to gain design knowledge as well as to be able to view design constraints constructively as special characteristics on the game board that may turn to their advantages rather than as useless stumbling blocks. Designing games requires students to analyze existing designs in great details as well as to be able to organize certain relationships of these details into operable rules that could produce new designs. The experience of teaching “games and design” to-date has been a very fruitful one. Future work will focus on design gaming for freshman students and game designing for senior students, as well as the interaction between the freshmen (game players) and the seniors (game designers).

title	Representing Floorplans for Interactive Evolutionary Design
source	AVOCAAD Second International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-02-07] Brussels (Belgium) 8-10 April 1999, pp. 343-346
summary	Computer tools that provide support in the early explorative phase of architectural design are rare. In order to explore the solution space of a design problem, architects in general rely on the use of paper and pencil. We are developing a system which will assist the designer in the exploration of a particular design problem, focusing initially on 2D floorplans. The format chosen for this system is one in which the computer, in interaction with the designer, "evolves" designs. A major obstacle associated with the use of an evolutionary approach is the adequate representation of a floorplan in a genome. We propose a tree-structure in which the nodes represent organising-principles that dictate how the leaves attached to it are organised. Figure 1 shows an example of a tree with four levels; the terminal nodes represent the elements to be placed. The first level no only represents an organising-principle, but also a contour; this contour is either fixed (e.g. dictated by the environment) or free to evolve. On either side of the tree-structure two interpretations of this tree are shown.

title	Modelling architectural design information by features : an approach to dynamic product modelling for application in architectural design
source	Eindhoven University of Technology
summary	Architectural design, like many other human activities, benefits more and more from the ongoing development of information and communication technologies. The traditional paper documents for the representation and communication of design are now replaced by digital media. CAD systems have replaced the drawing board and knowledge systems are used to integrate expert knowledge in the design process. Product modelling is one of the most promising approaches in the developments of the last two decades, aiming in the architectural context at the representation and communication of the information related to a building in all its aspects and during its complete life-cycle. However, after studying both the characteristics of the product modelling approach and the characteristics of architectural design, it is concluded in this research project that product modelling does not suffice for support of architectural design. Architectural design is characterised mainly as a problem solving process, involving illdefined problems that require a very dynamic way of dealing with information that concerns both the problem and emerging solutions. Furthermore, architectural design is in many ways an evolutionary process. In short term this is because of the incremental approach to problem solving in design projects; and in long term because of the stylistic development of designers and the continuous developments in the building and construction industry in general. The requirements that are posed by architectural design are concentrated in the keywords extensibility and flexibility of the design informationmodels. Extensibility means that designers can extend conceptual models with definitions that best suit the design concepts they wish to utilise. Flexibility means that information in design models can be structured in a way that accurately represents the design rationale. This includes the modelling of incidental characteristics and relationships of the entities in the model that are not necessarily predefined in a conceptual model. In general, product modelling does not adequately support this dynamic nature of design. Therefore, this research project has studied the concepts developed in the technology of Feature-based modelling, which originates from the area of mechanical engineering. These concepts include the usage of Features as the primitives for defining and reasoning about a product. Features have an autonomous function in the information model, which, as a result, constitutes a flexible network of relationships between Features that are established during the design process. The definition of Features can be specified by designers to formalise new design concepts. This allows the design tools to be adapted to the specific needs of the individual designer, enlarging the library of available resources for design. In addition to these key-concepts in Feature-based modelling as it is developed in the mechanical engineering context, the project has determined the following principles for a Feature-based approach in the architectural context. Features in mechanical engineering are used mainly to describe the lowest level of detail in a product's design, namely the characteristics of its parts. In architecture the design process does not normally follow a strictly hierarchical approach and therefore requires that the building be modelled as a whole. This implies that multiple levels of abstraction are modelled and that Features are used to describe information at the various abstraction levels. Furthermore, architectural design involves concepts that are non-physical as well as physical; Features are to be used for modelling both kinds. The term Feature is defined in this research project to reflect the above key-concepts for this modelling approach. A Feature is an autonomous, coherent collection of information, with semantic meaning to a designer and possibly emerging during design, that is defined to formalise a design concept at any level of abstraction, either physical or non-physical, as part of a building model. Feature models are built up entirely of Features and are structured in the form of a directed graph. The nodes in the graph are the Features, whereas the arcs are the relationships between the Features. Features can be of user-defined types and incidental relationships can be added that are not defined at the typological level. An inventory in this project of what kind of information is involved in the practice of modelling architectural design is based on the analysis of a selection of sources of architectural design information. This inventory is deepened by a case study and results in the proposition of a categorisation of architectural Feature types.

title	The comparison of animation, virtual reality, and scenario scripting in design process
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	Design media is a fundamental tool, which can incubate concrete ideas from ambiguous concepts. Evolved from freehand sketches, physical models to computerized drafting, modeling (Dave, 2000), animations (Woo, et al., 1999), and virtual reality (Chiu, 1999; Klercker, 1999; Emdanat, 1999), different media are used to communicate to designers or users with different conceptual levels¡@during the design process. Extensively employed in design process, physical models help designers in managing forms and spaces more precisely and more freely (Millon, 1994; Liu, 1996).Computerized drafting, models, animations, and VR have gradually replaced conventional media, freehand sketches and physical models. Diversely used in the design process, computerized media allow designers to handle more divergent levels of space than conventional media do. The rapid emergence of computers in design process has ushered in efforts to the visual impact of this media, particularly (Rahman, 1992). He also emphasized the use of computerized media: modeling and animations. Moreover, based on Rahman's study, Bai and Liu (1998) applied a new design media¡Xvirtual reality, to the design process. In doing so, they proposed an evaluation process to examine the visual impact of this new media in the design process. That same investigation pointed towards the facilitative role of the computerized media in enhancing topical comprehension, concept realization, and development of ideas.Computer technology fosters the growth of emerging media. A new computerized media, scenario scripting (Sasada, 2000; Jozen, 2000), markedly enhances computer animations and, in doing so, positively impacts design processes. For the three latest media, i.e., computerized animation, virtual reality, and scenario scripting, the following question arises: What role does visual impact play in different design phases of these media. Moreover, what is the origin of such an impact? Furthermore, what are the similarities and variances of computing techniques, principles of interaction, and practical applications among these computerized media?This study investigates the similarities and variances among computing techniques, interacting principles, and their applications in the above three media. Different computerized media in the design process are also adopted to explore related phenomenon by using these three media in two projects. First, a renewal planning project of the old district of Hsinchu City is inspected, in which animations and scenario scripting are used. Second, the renewal project is compared with a progressive design project for the Hsinchu Digital Museum, as designed by Peter Eisenman. Finally, similarity and variance among these computerized media are discussed.This study also examines the visual impact of these three computerized media in the design process. In computerized animation, although other designers can realize the spatial concept in design, users cannot fully comprehend the concept. On the other hand, other media such as virtual reality and scenario scripting enable users to more directly comprehend what the designer's presentation.Future studies should more closely examine how these three media impact the design process. This study not only provides further insight into the fundamental characteristics of the three computerized media discussed herein, but also enables designers to adopt different media in the design stages. Both designers and users can more fully understand design-related concepts.

title	APPLICATION OF SPATIAL DESIGN ABILITY IN A POSTGRADUATE COURSE
source	Full-scale Modeling and the Simulation of Light [Proceedings of the 7th European Full-scale Modeling Association Conference / ISBN 3-85437-167-5] Florence (Italy) 18-20 February 1999, pp. 75-82
summary	Spatial Design Ability (SDA) has been defined by the author (1983) as the capacity to anticipate the effects (psychological impressions) that architectural spaces or its components produce in observers or users. This concept, which requires the evaluation of spaces by the people that uses it, was proposed as a guideline to a Masters Degree Course in Architectural Design at the Universidad Autonoma de Aguascalientes in Mexico. The theory and the exercises required for the experience needed a model that could simulate spaces in terms of all the variables involved. Full-scale modeling as has been tested in previous research, offered the most effective mean to experiment with space. A simple, primitive model was designed and built: an articulated ceiling that allows variation in height and shape, and a series of wooden panels for the walls and structure. Several exercises were carried out, mainly to experience cause -effect relationships between space and the psychological impressions they produce. Students researched into spatial taxonomy, intentional sequences of space and spatial character. Results showed that students achieved the expected anticipation of space and that full-scale modeling, even with a simple model, proved to be an effective tool for this purpose. The low cost of the model and the short time it took to be built, opens an important possibility for Institutions involved in architectural studies, both as a research and as a learning tool.

title	Automated Cost Analysis of Concept Design BIM Models

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

summary	Since 1991 Virtual Reality has been used in student projects in the Building Information Technology group. It started as an experimental tool to assess the impact of VR technology in design, using the environment of the associated Calibre Institute. The technology was further developed in Calibre to become an important presentation tool for assessing design variants and final design solutions. However, it was only sporadically used in student projects. A major shift occurred in 1997 with a number of student projects in which various computer technologies including VR were used in the whole of the design process. In 1998, the new Design Systems group started a design studio with the explicit aim to integrate VR in the whole design process. The teaching effort was combined with the research program that investigates VR as a design support environment. This has lead to increasing number of innovative student projects. The paper describes the context and history of VR in Eindhoven and presents the current set-UP of the studio. It discusses the impact of the technology on the design process and outlines pedagogical issues in the studio work.

summary	The VR-DIS project aims to provide design support in the early design stage using a Virtual Reality environment. The initial brief of the design system is based on an analysis of a design case. The paper describes the process of analysis and extraction of design knowledge and design concepts in terms of Features. It is demonstrated how the analysis has lead to a classification of design concepts. This classification forms one of the main specifications for the VR-based design aid system that is being developed in the VR-DIS programme. The paper concludes by discussing the particular approach used in the case analysis and discusses future work in the VR-DIS research programme.
