title	Modeling Architectural Forms through Replacement Operations
doi	https://doi.org/10.52842/conf.acadia.1989.103

summary	Replacement operations, where an element at any topological level may be replaced by another element at the same or different topological level, are defined. Their potential as design tools which may be incorporated in a CAD system is investigated and demonstrated through the experimental implementation of two such operations in MARCOS, a Modeling Architectural Compositions System. MARCOS has been written in C. It is highly interactive and runs on an Apple Macintosh IIx. The two operations which have been implemented are the face -> volume and volume -> volume replacements. They were chosen for their potential as generators of architectural forms. Examples of architectural compositions produced through the use of replacement operations are also illustrated.

title	Interactive design of parameterized 3D models by direct manipulation
source	Delft University of Technology
summary	The practical applicability of a computer-aided design system is strongly influenced by both the user interface and the internal model representation. A well designed user interface facilitates the communication with the system by offering an intuitive environment for for specification and representation of model information. An internal model representation, capable of storing geometric, topological and hierarchical dependencies between components in a model, increases the efficiency of the system by facilitating modification and elaboration of the model during the different stages of the design process. The subject of this thesis is the integration of a high level parameterized model representation with direct manipulation interface techniques for the design of three-dimensional objects. A direct manipulation interface enables the user to specify a model by interaction on a graphical representation, as an alternative for an abstract and error-prone apha-numerical dialogue style. A high level model representation is obtained by using a procedural modeling language with general purpose control structures, including arithmetic and logical expressions, repetition, conditionals, functions and procedures, and dedicated data types such as coordinate systems, geometric primitives and geometric constraints. The language interpreter is interconnected with a graphical interface, an incremental constraint solver and a geometrical modeler, using visual programming techniques. The developed techniques are implemented in a modeling system called GeoNode. The system incorporates paradigms of object-oriented design, with respect to both the user interface and to the system implementation. The applicability of the presented techniques is illustrated by examples in application domains such as solid modeling, kinematic analysis, feature modeling and top-down design.

title	A Primitive-Instancing Interactive 3-D Modeling System for Spatial Design Studies
source	The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [CAAD Futures ‘89 Conference Proceedings / ISBN 0-262-13254-0] Cambridge (Massachusetts / USA), 1989, pp. 457-468
summary	The authors have developed a basic, interactive, primitive-instancing 3-D modeling system (CAADF), which is based on a high-speed 3-D color graphic workstation, and have tested its potential ability to support spatial design studies in an architectural design studio. After- a review of work performed by a student with the system, this paper concludes that this system provides an attractive environment for spatial design studies which conventional CAD systems have not achieved. The interactive process of 3-D modeling in perspective or isometric view images and the dynamic viewing utility are the most successful features of the system. In contrast to those advantages, the resolution of color graphic display is a limitation of the system. The authors conclude that if sufficiently many appropriate 3-D geometric primitives are supported by a CAD system, a primitive instancing method can significantly reduce the work entailed in object modeling.

title	Using high-level constraints to aid space planning applications in computer-aided design
source	University of Toronto, Department of Computer Science
summary	This thesis describes a system that aids in solving space planning and layout design problems through an innovative use of constraints. Space planning problem solving is aided by constrained manipulation, a trial-and-error approach, and modelling the scaling properties of objects. Constraints are used to model various physical properties of solid objects (including gravity and friction) and to control the way in which objects scale. The system runs on a Silicon Graphics workstation supporting interactive, real-time, 3-dimensional graphics that aid in visualizing designs. The problems handled by our prototype are restricted to objects representable with rectangular solids oriented along the cartesian axes. This system was used by designers and novice computer users to solve a studio layout problem. Constraints were found to aid in the manipulation of objects by providing predictable behaviour for objects. The test results indicate that subjects learn the behaviour of objects easily and use this information in useful ways. In addition, there are indications that constraints can reduce users' cognitive loads at the user interface level. The coupling of constraints with the interactive, 3-dimensional aspect of the system encourages the use of the system at earlier stages of the design process than simple geometric drafting systems.

title	Light Table: An Interface To Visual Information Systems
source	The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [CAAD Futures ‘89 Conference Proceedings / ISBN 0-262-13254-0] Cambridge (Massachusetts / USA), 1989, pp. 229-238
summary	A primary aim of the Light Table project was to see if a combination of the optical laser disc, local area networks, and interactive videographic workstation technology could bring a major visual collection, (such as the Rotch Visual Collections of the Massachusetts Institute of Technology), to a campuswide population of undergraduate users. VIS (Visual Information System) is the name being given to the new genre of information technology. Much research and development effort is currently being applied to areas where the image has a special significance, for example in architecture and planning, in graphic and fine arts, in biology, in medicine, and in photography. One particular advance in the technology of VIS has been the facility to access visual information across a distributed computer system via LAN (Local Area Networks) and video delivery systems, (such as campus TV cable). This advance allows users to retrieve images from both local and remote sources, dispatching the image search through the LAN, and receiving the images back at their workstation via dedicated channels on the campus TV cable. Light Table is the title of a system that acts as a computer-based interactive videographic interface to a variety of visual information systems described in the body of this paper. It takes its name from the traditional, back- lit, translucent light table that lecturers use to assemble and view collections of slides for talks and seminars. The component of Light Table which is being reported in greatest detail here, a software outcome called Galatea, is a versatile and robust system capable of controlling video devices in a networked environment.

title	A model appraising the performance of structural systems used in sports hall and swimming pool buildings in greece
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	The selection of the best performing structural system (among steel, timber laminated, concrete, fabric tents) for medium span (30-50m) sports halls and swimming pools in Greece formed the impetus for this research. Decision-making concerning selection of the structural system is difficult in this sector of construction, as was explained in the "Long Span Structures" conference (November 1990, Athens. Greece). From the literature it has been found that most building appraisals end up at the level of data analysis and draw conclusions on the individual aspects they investigate. These approaches usually focus on a fraction of the problem, examining it very deeply and theoretically. Their drawback is loss of comprehensiveness and ability to draw conclusions on an overall level and consequently being applicable to the existing conditions. Research on an inclusive level is sparse. In this particular research project, an inclusive appraisal approach was adopted, leading to the identification of three main variables: resources, human-user-satisfaction, and technical. Consequently, this led to a combination of purely quantitative and qualitative data. Case studies were conducted on existing buildings in order to assess the actual performance of the various alternative structural systems. This paper presents the procedure followed for the identification of the research variables and the focus on the development of the model of quantification. The latter is of vital importance if the problem of incompatibility of data is to be solved, overall relation of findings is to be achieved and holistic conclusions are to be drawn.

title	The Computerized Design Firm
source	The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [CAAD Futures ‘89 Conference Proceedings / ISBN 0-262-13254-0] Cambridge (Massachusetts / USA), 1989, pp. 317-332
summary	This paper is not just about the future of computerized design practice. It is about what to do today in contemplation of tomorrow-the issues of computercentered practice and the courses of action open to us can be discerned by the careful observer. The realities of computerized design practice are different from the issues on which design education still fixes its attention. To educators, the present paper recommends further clinical research on computerized design firms and suggests that case studies on the matter be developed and utilized as teaching material. Research conducted by the author of this paper indicates that a new form of design firm is emerging-the computerized design firm-totally supported and augmented by the new information technology. The present paper proceeds by introducing an abridged case study of an actual totally electronic, computerized design practice. Then, the paper concentrates on modelling the computerized design firm as an intelligent system, indicating non-trivial changes in its structure and strategy brought about by the introduction of the new information technology into its operations - among other considerations, different strategies and diverse conceptions of management and workgroup roles are highlighted. In particular, this paper points out that these structural and strategic changes reflect back on the technology of information with pressures to redirect present emphasis on the individual designer, working alone in an isolated workstation, to a more realistic conception of the designer as a member of an electronic workgroup. Finally, the paper underlines that this non-trivial conception demands that new hardware and software be developed to meet the needs of the electronic workgroup - which raises issues of human-machine interface. Further, it raises the key issues of how to represent and expose knowledge to users in intelligent information - sharing systems, designed to include not only good user interfaces for supporting problem-solving activities of individuals, but also good organizational interfaces for supporting the problem-solving activities of groups. The paper closes by charting promising directions for further research and with a few remarks about the computerized design firm's (near) future.

title	Systems Thinking, Systems Practice
source	John Wiley & Sons, Chichester
summary	Whether by design, accident or merely synchronicity, Checkland appears to have developed a habit of writing seminal publications near the start of each decade which establish the basis and framework for systems methodology research for that decade."" Hamish Rennie, Journal of the Operational Research Society, 1992 Thirty years ago Peter Checkland set out to test whether the Systems Engineering (SE) approach, highly successful in technical problems, could be used by managers coping with the unfolding complexities of organizational life. The straightforward transfer of SE to the broader situations of management was not possible, but by insisting on a combination of systems thinking strongly linked to real-world practice Checkland and his collaborators developed an alternative approach - Soft Systems Methodology (SSM) - which enables managers of all kinds and at any level to deal with the subtleties and confusions of the situations they face. This work established the now accepted distinction between hard systems thinking, in which parts of the world are taken to be systems which can be engineered, and soft systems thinking in which the focus is on making sure the process of inquiry into real-world complexity is itself a system for learning. Systems Thinking, Systems Practice (1981) and Soft Systems Methodology in Action (1990) together with an earlier paper Towards a Systems-based Methodology for Real-World Problem Solving (1972) have long been recognized as classics in the field. Now Peter Checkland has looked back over the three decades of SSM development, brought the account of it up to date, and reflected on the whole evolutionary process which has produced a mature SSM. SSM: A 30-Year Retrospective, here included with Systems Thinking, Systems Practice closes a chapter on what is undoubtedly the most significant single research programme on the use of systems ideas in problem solving. Now retired from full-time university work, Peter Checkland continues his research as a Leverhulme Emeritus Fellow. "

title	A digital Procedure of Building Construction: A practical project

summary	In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

title	Knowledge Based Interpretation of Architectural Drawings
source	Massachusetts Institute of Technology, Department of Civil Engineering, Cambridge, MA
summary	Architectural schematic drawings have been used to communicate building designs for centuries. The symbolic language used in these drawings efficiently represents much of the intricacy of the building process (e.g. implied business relationships, common building practice, and properties of construction materials). The drawing language is an accepted standard representation for building design, something that modern data languages have failed to achieve. In fact, the lack of an accepted standard electronic representation has hampered efforts at computer intergration and perhaps worsened industry fragmentation. In general, drawings must be interpreted, by a professional, and then reentered in order to transfer them from one CAD system to another. This work develops a method for machine interpretation of architectural (or other) schematic drawings. The central problem is to build an efficient drawing parser (i.e. a program that identifies the semantic entitites, characteristics, and relationships that are represented in the drawing). The parser is built from specifications of the drawing grammar and an underlying spatial model. The grammar describes what to look for, and the spatial model enables the parser to find it quickly. Coupled with existing optical recognition technology, this technique enables the use of drawings directly as: (1) a database to drive various AEC applications, (2) a communication protocol to integrate CAD systems, (3) a traditional user interface.

title	Vector Field Representation for the Evaluation of Multiple Performance Variables
source	1990. 6, [7] p., [3] p. of ill. includes bibliography
summary	A vector field representation is proposed to simulate the spatial distribution of four building system performance variables: light, sound, radiant heat, and air flow. From this simulation, a measure of the impact of adding, deleting, or modifying an object in the field is computed. This measure serves as a passive evaluation of the user/designer's decision to modify the location or dimensions of the object in a space. This process of simulation-evaluation is performed by a performance module (PM), which is viewed as a component of a CAAD System (Computer Architectural Aided Design). This paper describes the motivation, objectives, methodology and preliminary results of the approach

title	Virtual Reality and the Future of Publishing Archaeological Excavations: the multimedia publication of the prehistoric settlement on Tsoungiza at Ancient Nemea
source	New York: The Metropolitan Museum of Art
summary	The Nemea Valley Archaeological Project is a study of settlement and land use in a regional valley system in Greece extending from the Upper Paleolithic until the present. Active field research was conducted by four teams between 1981 and 1990. The first component was a regional archaeological survey. Second, and closely related to the first, was a social anthropological study of modern settlement and land use. Next was a team assigned to excavate the succession of prehistoric settlements of Ancient Nemea on Tsoungiza. Last, historical ecologists, a palynologist, and a geologist formed the environmental component of the research. As a result of advances in electronic publishing, plans for the final publication of the Nemea Valley Archaeological Project have evolved. Complete publication of the excavation of the prehistoric settlements of Ancient Nemea on Tsoungiza will appear in an interactive multimedia format on CD/DVD in Fall 2000. This project is planned to be the first electronic publication of the American School of Classical Studies at Athens. We have chosen to publish in electronic format because it will meet the needs and interests of a wider audience, including avocational archaeologists, advanced high school and college students, graduate students, and professional archaeologists. The multimedia format on CD/DVD will permit the inclusion of text, databases, color and black-and-white images, two and three-dimensional graphics, and videos. This publication is being developed in cooperation with Learning Sites, Inc., which specializes in interactive three-dimensional reconstructions of ancient worlds http://www.learningsites.com. The Nemea Valley Archaeological Project is particularly well prepared for the shift towards electronic publishing because the project's field records were designed for and entered in computer databases from the inception of the project. Attention to recording precise locational information for all excavated objects enables us to place reconstructions of objects in their reconstructed architectural settings. Three-dimensional images of architectural remains and associated features will appear both as excavated and as reconstructed. Viewers will be able to navigate these images through the use of virtual reality. Viewers will also be able to reference all original drawings, photographs, and descriptions of the reconstructed architecture and objects. In this way a large audience will be able to view architectural remains, artifacts, and information that are otherwise inaccessible.

summary	Conventional computer systems currently used by architecture and landscape architecture are not addressing complex decision making, system interface, dynamic manipulation and real time visualization of data. This paper identifies a strategy by which Canadian Schools could form a supportive network, incorporate and expand their research development. Within this larger framework schools would have better tools, a larger research base and access to funding as a group. The following discussion is an idea of what we at the Canadian Schools need to do differently over the next five years in our research and teaching in order to make a unique contribution to our fields.

summary	The capacity of most computer-aided design systems is inadequate to represent landscape architectural ideas and compute landscape scenes quickly. As part of our teaching agenda, we decided to write software for the Silicon Graphics Iris workstations to tackle this problem directly. This paper begins with a discussion of our concerns about the use of CAD tools in the representation of landscape architectural space. Secondly, we discuss the approach that Toronto takes to computing and teaching with particular emphasis on the use of computers to support an integrated representational work environment. Finally, a fourth-year design studio that used our software is reviewed. Static illustrations of the system are presented here, although there is a videotape that demonstrates the dynamic nature of the system.

summary	Environmental designers, design educators and design students using computers are a constituency with a set of requirements for database structure and flexibility, for knowledge representation and inference mechanisms, and for both graphical and non-graphical operations, that are now articulatable and to-date largely unmet. This is especially so in the area called 'preliminary' or 'schematic' design, where our requirements are related to, but different from, those of our colleagues in mechanical and electrical engineering, whose needs have dominated the notable developments in this area. One manifestation of these needs is in the peculiar form of graphics called diagrams , and the ways in which environmental designers (architects, landscape architects., urban designers) use them. Our diagrams are both similar to and different from structural, circuit, or logical diagrams in important ways. These similarities and differences yield basic insights into designing and design knowledge, and provide guidance for some necessary steps in the development of the next generation of CAD systems. Diagrams as a form of knowledge representation have received little scrutiny in the literature of graphic representation and computer graphics. In the following sections I present an overview of the theoretical basis for distinguishing and using diagrams; examine some of the computational requirements for a system of computer-aided diagramming; describe a prototype implementation called CBD (Constraint Based Diagrammer) and illustrate one example of its use; and speculate on the implications and potential applications of these ideas in computer-aided design education.

For the prosecution of the data files were generated inprograms attended by such computer as: AutoCAD R14 and 2000, Microsoft Word, Microsoft PowerPoint and MicrosoftAccess 2000, CorelDRAW V9.0 and Corel PHOTOPAINT V9.0.The investigation is related with the work developed in the class of Graphic Calculation II, belonging to the Departmentof Communication of the School of Architecture of the Faculty of Architecture and Design of The University of the Zulia(FADLUZ), carried out from the year 1999, using part of the obtained information of the works of the students generatedby means of the CAD systems for the representation in three dimensions of constructions with historical relevance in themodern architecture of Maracaibo, which are classified in the work of The Other City, generating different types ofisometric views, perspectives, representations photorealistics, plants and facades, among others.In what concerns to the thematic of this investigation, previous antecedents are ignored in our environment, and beingthe first time that incorporates the digital graph applied to the work carried out by the architects of “The Other City, thegenesis of the oil city of Maracaibo” carried out in the year 1994; of there the value of this research the field of thearchitecture and computer science. To point out that databases exist in the architecture field fits and of the design, alsoweb sites with information has more than enough architects and architecture works (Montagu, 1999).In The University of the Zulia, specifically in the Faculty of Architecture and Design, they have been carried out twoworks related with the thematic one of database, specifically in the years 1995 and 1996, in the first one a system wasdesigned to visualize, to classify and to analyze from the architectural point of view some historical buildings of Maracaiboand in the second an automated system of documental information was generated on the goods properties built insidethe urban area of Maracaibo. In the world environment it stands out the first database developed in Argentina, it is the database of the Modern andContemporary Architecture “Datarq 2000” elaborated by the Prof. Arturo Montagú of the University of Buenos Aires. The general objective of this work it was the use of new technologies for the prosecution in Architecture and Design (MONTAGU, Ob.cit). In the database, he intends to incorporate a complementary methodology and alternative of use of the informationthat habitually is used in the teaching of the architecture. When concluding this investigation, it was achieved: 1) analysis of projects of modern architecture, of which some form part of the historical patrimony of Maracaibo; 2) organized registrations of type text: historical, formal, space and technical data, and graph: you plant, facades, perspectives, pictures, among other, of the Moments of the Architecture of the Modernity in the city, general data and more excellent characteristics of the constructions, and general data of the Planners with their more important works, besides information on the parcels where the constructions are located, 3)construction in digital format and development of representations photorealistics of architecture projects already built. It is excellent to highlight the importance in the use of the Technologies of Information and Communication in this investigation, since it will allow to incorporate to the means digital part of the information of the modern architecturalconstructions that characterized the city of Maracaibo at the end of the XX century, and that in the last decades they have suffered changes, some of them have disappeared, destroying leaves of the modern historical patrimony of the city; therefore, the necessity arises of to register and to systematize in digital format the graphic information of those constructions. Also, to demonstrate the importance of the use of the computer and of the computer science in the representation and compression of the buildings of the modern architecture, to inclination texts, images, mapping, models in 3D and information organized in databases, and the relevance of the work from the pedagogic point of view,since it will be able to be used in the dictation of computer science classes and history in the teaching of the University studies of third level, allowing the learning with the use in new ways of transmission of the knowledge starting from the visual information on the part of the students in the elaboration of models in three dimensions or electronic scalemodels, also of the modern architecture and in a future to serve as support material for virtual recoveries of some buildings that at the present time they don’t exist or they are almost destroyed. In synthesis, the investigation will allow to know and to register the architecture of Maracaibo in this last decade, which arises under the parameters of the modernity and that through its organization and visualization in digital format, it will allow to the students, professors and interested in knowing it in a quicker and more efficient way, constituting a contribution to theteaching in the history area and calculation. Also, it can be of a lot of utility for the development of future investigation projects related with the thematic one and restoration of buildings of the modernity in Maracaibo.

title	SEED: A Software Environment to Support the Early Phases in Building Design
source	Proceeding of IKM '94, Weimar, Germany, pp. 5-10
summary	The SEED project intends to develop a software environment that supports the early phases in building design (Flemming et al., 1993). The goal is to provide support, in principle, for the preliminary design of buildings in all aspects that can gain from computer support. This includes using the computer not only for analysis and evaluation, but also more actively for the generation of designs, or more accurately, for the rapid generation of design representations. A major motivation for the development of SEED is to bring the results of two multi-generational research efforts focusing on `generative' design systems closer to practice: 1. LOOS/ABLOOS, a generative system for the synthesis of layouts of rectangles (Flemming et al., 1988; Flemming, 1989; Coyne and Flemming, 1990; Coyne, 1991); 2. GENESIS, a rule-based system that supports the generation of assemblies of 3-dimensional solids (Heisserman, 1991; Heisserman and Woodbury, 1993). The rapid generation of design representations can take advantage of special opportunities when it deals with a recurring building type, that is, a building type dealt with frequently by the users of the system. Design firms - from housing manufacturers to government agencies - accumulate considerable experience with recurring building types. But current CAD systems capture this experience and support its reuse only marginally. SEED intends to provide systematic support for the storing and retrieval of past solutions and their adaptation to similar problem situations. This motivation aligns aspects of SEED closely with current work in Artificial Intelligence that focuses on case-based design (see, for example, Kolodner, 1991; Domeshek and Kolodner, 1992; Hua et al., 1992).

title	Generative and Evolutionary Techniques for Building Envelope Design
source	International Conference on Generative Art
summary	The authors have been involved in the use of generative techniques for building envelope design since 1968 and the use of genetic algorithms since 1990. Recent work has focused on incorporating optimisation functions into form generating processes in order for new forms responding to varied design environments to be created and determined. This paper will summarise the authors’ previous work in this field and explain the theory behind this approach, and illustrate recent developments. While the initial implementation of a new building envelope design system is reported in more details in a related paper at this conference, this paper outlines its main features and points out the direction at which it is to be fully developed and further improved.
