title Requirements for Developing an Information System for Architecture
source CAAD futures ‘87 [Conference Proceedings / ISBN 0-444-42916-6] Eindhoven (The Netherlands), 20-22 May 1987, pp. 149-170
summary This paper discusses possibilities of developing new tools for architectural design. It argues that architects should meet the challenge of information technology and computer-based design techniques. One such attempt has been the first phase of the development of an architectural design information system (ADIS), also an architectural design decision support system. The system should benefit from the developments of the artificial intelligence to enable the architect to have access to information required to carry out design work. In other words: the system functions as a huge on-line electronic library of architecture, containing up-to-date architectural design information, literature, documents, etc. At the same time, the system offers necessary design aids such as computer programs for design process, drawing programs, evaluation programs, cost calculation programs, etc. The system also provides data communication between the architect and members of the design coalition team. This is found to be of vital importance in the architectural design process, because it can enable the architect to fit in changes, brought about in the project by different parties. Furthermore, they will be able, to oversee promptly the consequences of changes or decisions in a comprehensive manner. The system will offer advantages over the more commonly applied microcomputer based CAAD and IGDM (integrated graphics database management) systems, or even larger systems available to an architect. Computer programs as well as hardware change rapidly and become obsolete. Therefore, unrelenting investment pressure to up-date both software and hardware exists. The financial burden of this is heavy, in particular for smaller architectural practices (for instance an architect working for himself or herself and usually with few or no permanent staff). ADIS, as an on-line architectural design aid, is constantly up-dated by its own organisation. This task will be co-ordinated by the ADIS data- base administrator (DBA). The processing possibilities of the system are faster, therefore more complex processing tasks can be handled. Complicated large graphic data files, can be easily retrieved and manipulated by ADIS, a large system. In addition, the cost of an on-line system will be much less than any other system. The system is based on one model of the architectural design process, but will eventually contain a variety of design models, as it develops. The development of the system will be an evolutionary process, making use of its users' feed-back system. ADIS is seen as a step towards full automation of architectural design practices. Apart from being an architectural design support system, ADIS will assist the architect in his/her administrative and organisational activities.

title The Digital Design Process: reflections on architectural design positions on complexity and CAAD
source Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary These instructions are intended to guide contributors to the Second Architecture is presently engaged in an impatient search for solutions to critical questions about the nature and the identity of the discipline, and digital technology is a key agent for prevailing innovations in architectural design. The problem of complexity underlies all design problems. With the advent of CAD however, Architect’s ability to truly represent complexity has increased considerably. Another source that provides information about dealing with complexity is architectural theory. As Rowe (1987) states, architectural theory constitutes “a corpus of principles that are agreed upon and therefore worthy of emulation”. Architectural theory often is a mixed reflection on the nature of architectural design, design processes, made in descriptive and prescriptive terms (see Kruft 1985). Complexity is obviously not a new issue in architectural theory. Since it is an inherent characteristic of design problems, it has been dealt with in many different ways throughout history. Contemporary architects incorporate the computer in their design process. They produce architecture that is generated by the use of particle systems, simulation software, animation software, but also the more standard modelling tools. The architects reflect on the impact of the computer in their theories, and display changes in style by using information modelling techniques that have become versatile enough to encompass the complexity of information in the architectural design process. In this way, architectural style and theory can provide directions to further develop CAD. Most notable is the acceptance of complexity as a given fact, not as a phenomenon to oppose in systems of organization, but as a structuring principle to begin with. No matter what information modelling paradigm is used, complex and huge amounts of information need to be processed by designers. A key aspect in the combination of CAD, complexity, and architectural design is the role of the design representation. The way the design is presented and perceived during the design process is instrumental to understanding the design task. More architects are trying to reformulate this working of the representation. The intention of this paper is to present and discuss the current state of the art in architectural design positions on complexity and CAAD, and to reflect in particular on the role of digital design representations in this discussion. We also try to investigate how complexity can be dealt with, by looking at architects, in particular their styles and theories. The way architects use digital media and graphic representations can be informative how units of information can be formed and used in the design process. A case study is a concrete architect’s design processes such as Peter Eisenman Rem Koolhaas, van Berkel, Lynn, and Franke gehry, who embrace complexity and make it a focus point in their design, Rather than viewing it as problematic issue, by using computer as an indispensable instrument in their approaches.

title Natural Language Interface for CAAD System
source CAAD futures ‘87 [Conference Proceedings / ISBN 0-444-42916-6] Eindhoven (The Netherlands), 20-22 May 1987, pp. 137-148
summary This work explores issues involved in the development of a natural interface for man-machine dialogue in architectural design processes. A hand-touch on an interactive surface is suggested as the best natural-language interface for architectural CAD systems. To allow the development of a rich range of hand-touch natural-language for communicating information and commands to the computer, it is proposed to develop a new type of a touch-panel, for which a set of specifications is presented. A conceptual design of an architectural workstation, having the described touch-panel, is presented. This workstation is characterized by the integration of the entire range of control and communication facilities required for any architectural task into a single interactive unit. The conceptual model for this workstation is the standard size drawing board, on which the architect is accustomed to spread documents, drawings, books and tools, shuffle them around and interchange them freely by using the natural-language interface developed in this work. The potential of the suggested hand-touch natural-language and the proposed workstation are demonstrated by a case-study.

summary L'institution architecturale est organisée à partir du postulat d'une incommunicabilité de l'architecture ("I'espace indicible" de Le Corbusier, par exemple), ce qui ne facilite pas l'enseignement ni l'exercice professionnel. Comme l'ont montré divers travaux théoriques, ce postulat n'a rien de nécessaire, bien qu'il joue un rôle institutionnel historiquement situé. Une activité pratique de communication de l'architecture par la vidéo conduit à la même conclusion: bien des opportunités existent d'exploiter les techniques médiatiques contemporaines pour les mettre au service de l'architecture, de son enseignement et des pratiques professionnelles. La présentation s'appuie sur quinze ans d'expérience d'enseignement et de production de vidéos dans l'Ecole d'architecture de l'Université de Genève ayant permis la réalisation d'une centaine d'émissions sur l'architecture, la construction et l'urbanisme.

title Expertise of the Architect
source November, 1987. [13] p. unevenly numbered : ill. includes bibliography
summary One of the areas where the expertise of the seasoned architect comes out is in the initial structuring of design problems. During problem structuring the parameters and processes used in design are defined. Experienced architects modify these parameters both in global and local levels as a function of the success of their research process. Experienced architects also rely on 'scenarios' acquired through pervious experiences with similar problems to initialize their problem structures or to redefined them

title Geometrical Fundamentals for Design and Visualization of Spatial Objects
source CAAD futures ‘87 [Conference Proceedings / ISBN 0-444-42916-6] Eindhoven (The Netherlands), 20-22 May 1987, pp. 171-178
summary Every architectural object is a 3-dimensional entity of the human environment, haptically tangible and optically visible. During the architectural process of planning every object should be designed as a body and should be visualized in pictures. Thus the parts of construction get an order in space and the steps of construction get an order in time. The ideal planning object is a simulated anticipation of the real building object, which is to be performed later on. The possibility to relate the planning object immediately to the building object relies on the fact that they both have the same "geometry" This means: both can be described in the same geometric manner. Creating and visualizing spatial objects is based on geometrical fundamentals. Theoretical knowledge and practical control of these fundamentals is essential for the faultless construction and the realistic presentation of architectural objects. Therefore they have to be taught and learned thoroughly in the course of an architectural education. Geometrical design includes the forming of object- models (geometry of body boundaries), the structuring of object-hierarchies (geometry of body combinations) and the colouring of objects. Geometrical visualization includes controlling the processes of motion, of the bodies (when moving objects) and of the center of observation (when moving subjects) as well as the representation of 3-dimensional objects in 2- dimensional pictures and sequences of pictures. All these activities of architects are instances of geometrical information processing. They can be performed with the aid of computers. As for the computer this requires suitable hardware and software, as for the architect it requires suitable knowledge and capabilities to be able to talk about and to recall the perceivable objects and processes of the design with logic abstracts (language of geometry). In contrast to logical, numerical and textual informations the geometric informations concerning spatial objects are of much higher complexity. Usually these complexes of information are absorbed, processed and transmitted by the architect in a perceptive manner. The computer support in the field of geometry assumes that the processing of perceptions of the human consciousness can be converted by the computer as a framework of logical relations. Computer aided construction and representation require both suited devices for haptical and optical communication and suitable programs in particular.

summary A well-known Finnish novel characterizes the agrarian way of life by the following words: In the beginning there was a marsh, a hoe and John. John turned the marsh into a fertile corn field by means of the Finnish "sisu" or perseverance. We may draw a parallel to architectural design and say that in the beginning there was the idea of the architect only after that came various tools. Nevertheless, the method of visualization - image in its many forms - is something quintessential in architectural planning and design: it plays a central role as a tool for the designer's own thinking and evaluation, in general communication of planning, and in the communication between the designer and other parties of the planning process. Different sketches give directly visual interpretations to different consequences. The needs for the communication of planning in itself have grown along with the manifold development of public communication. Accordingly, the communication of planning has to compete with the highly-developed commercial communication.

doi https://doi.org/10.52842/conf.acadia.1987.019
summary A pilot experiment was conducted in the use of microcomputers and Computer Aided Design (CAD) software for architectural design education. The CAD workstations were incorporated into two consecutive semesters of the third year design studio and consisted of TANDY 3000 HD (tm) microcomputers with 20 megabyte hard disks, digitizer tablets, digitizer mice, enhanced graphics capabilities, dot-matrix printers and multi-pen plotters. Software packages included the Personal Architect (tm), VersaCAD (tm), DataCAD (tm), word processing software etc. Student to machine ratio of 4 to 1 was maintained and the use of the equipment was made available to students for approximately 20 hours per day.

Design assignments neither emphasized nor required the use of CAD techniques, as the experiment was designed to measure the students' acceptance of and adaptation to the use of CAD tools. The objective was to "teach" design in the traditional sense of a design studio, while making the computer an integral part of the setting in which the student learned designing and problem solving.

Measurements were made of (1) time for the "fundamentals" learning curve, (2) time for a "basic competence" learning curve, (3) hours utilized by categories of type of use, (4) hours utilized by equipment and software type, and (5) progress in design ability as evaluated by the traditional jury review methods.

doi https://doi.org/10.52842/conf.acadia.1994.039
summary Several studies have discussed the limitations of the available CAAD tools and have proposed solutions [Brown and Novitski 1987, Brown 1990, Degelman and Kim 1988, Schuman et al 1988]. The lack of integration between the different tasks that these programs address and the design process is a major problem. Schuman et al [1988] argued that in architectural design many issues must be considered simultaneously before the synthesis of a final product can take place. Studies by Brown and Novitski [1987] and Brown [1990] discussed the difficulties involved with integrating technical considerations in the creative architectural process. One aspect of the problem is the neglect of technical factors during the initial phase of the design that, as the authors argued, results from changing the work environment and the laborious nature of the design process. Many of the current programs require the user to input a great deal of numerical values that are needed for the energy analysis. Although there are some programs that attempt to assist the user by setting default values, these programs distract the user with their extensive arrays of data. The appropriate design tool is the one that helps the user to easily view the principal components of the building design and specify their behaviors and interactions. Data abstraction and information parsimony are the key concepts in developing a successful design tool. Three different approaches for developing an appropriate CAAD tool were found in the literature. Although there are several similarities among them, each is unique in solving certain aspects of the problem. Brown and Novitski [1987] emphasize the learning factor of the tool as well as its highly graphical user interface. Degelman and Kim [1988] emphasize knowledge acquisition and the provision of simulation modules. The Windows and Daylighting Group of Lawrence Berkeley Laboratory (LBL) emphasizes the dynamic structuring of information, the intelligent linking of data, the integrity of the different issues of design and the design process, and the extensive use of images [Schuman et al 19881, these attributes incidentally define the word hypermedia. The LBL model, which uses hypermedia, seems to be the more promising direction for this type of research. However, there is still a need to establish a new model that integrates all aspects of the problem. The areas in which the present research departs from the LBL model can be listed as follows: it acknowledges the necessity of regarding the user as the center of the CAAD tool design, it develops a model that is based on one of the high level theories of human-computer interaction, and it develops a prototype tool that conforms to the model.

summary The thesis of this paper is that architects work in a manner that is antithetical to problem-solving because they cannot explicate desired effects prior to their realization through the design process. In an attempt to clarify architecture's uncommon mode of action the author suggests that instead of specifying what they are trying to accomplish prior to their attempts to accomplish it as problem-solver do, architects treat design as a search for the most appropriate effects that can be attained in a unique context. They seek sets of combinatorial rules that will result in an internally consistent fit between a kit of parts and the effects that are achieved when those parts are assembled in a certain way

title Thonet Chairs Design Grammar: a Step Towards the Mass Customization of Furniture
source Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 181-200.
summary The paper presents the first phase of research currently under development that is focused on encoding Thonet design style into a generative design system using a shape grammar. The ultimate goal of the work is the design and production of customizable chairs using computer assisted tools, establishing a feasible practical model of the paradigm of mass customization (Davis, 1987). The current research step encompasses the following three steps: (1) codification of the rules describing Thonet design style into a shape grammar; (2) implementing the grammar into a computer tool as parametric design; and (3) rapid prototyping of customized chair designs within the style. Future phases will address the transformation of the Thonet’s grammar to create a new style and the production of real chair designs in this style using computer aided manufacturing. Beginning in the 1830’s, Austrian furniture designer Michael Thonet began experimenting with forming steam beech, in order to produce lighter furniture using fewer components, when compared with the standards of the time. Using the same construction principles and standardized elements, Thonet produced different chairs designs with a strong formal resemblance, creating his own design language. The kit assembly principle, the reduced number of elements, industrial efficiency, and the modular approach to furniture design as a system of interchangeable elements that may be used to assemble different objects enable him to become a pioneer of mass production (Noblet, 1993). The most paradigmatic example of the described vision of furniture design is the chair No. 14 produced in 1858, composed of six structural elements. Due to its simplicity, lightness, ability to be stored in flat and cubic packaging for individual of collective transportation, respectively, No. 14 became one of the most sold chairs worldwide, and it is still in production nowadays. Iconic examples of mass production are formally studied to provide insights to mass customization studies. The study of the shape grammar for the generation of Thonet chairs aimed to ensure rules that would make possible the reproduction of the selected corpus, as well as allow for the generation of new chairs within the developed grammar. Due to the wide variety of Thonet chairs, six chairs were randomly chosen to infer the grammar and then this was fine tuned by checking whether it could account for the generation of other designs not in the original corpus. Shape grammars (Stiny and Gips, 1972) have been used with sucesss both in the analysis as in the synthesis of designs at different scales, from product design to building and urban design. In particular, the use of shape grammars has been efficient in the characterization of objects’ styles and in the generation of new designs within the analyzed style, and it makes design rules amenable to computers implementation (Duarte, 2005). The literature includes one other example of a grammar for chair design by Knight (1980). In the second step of the current research phase, the outlined shape grammar was implemented into a computer program, to assist the designer in conceiving and producing customized chairs using a digital design process. This implementation was developed in Catia by converting the grammar into an equivalent parametric design model. In the third phase, physical models of existing and new chair designs were produced using rapid prototyping. The paper describes the grammar, its computer implementation as a parametric model, and the rapid prototyping of physical models. The generative potential of the proposed digital process is discussed in the context of enabling the mass customization of furniture. The role of the furniture designer in the new paradigm and ideas for further work also are discussed.

title Spatial reasoning: improving computational efficiency
source Automation in Construction 9 (4) (2000) pp. 361-367
summary When spatial data is analysed the result is often very computer intensive: even by the standards of contemporary technologies, the machine power needed is great and the processing times significant. This is particularly so in 3-D and 4-D scenarios. What we describe here is a technique, which tackles this and associated problems. The technique is founded in the idea of quad-tesseral addressing; a technique, which was originally applied to the analysis of atomic structures. It is based on ideas concerning Hierarchical clustering developed in the 1960s and 1970s to improve data access time [G.M. Morton, A computer oriented geodetic database and a new technique on file sequencing, IBM Canada, 1996.], and on atomic isohedral (same shape) tiling strategies developed in the 1970s and 1980s concerned with group theory [B. Grunbaum, G.C. Shephard, Tilings and Patterns, Freeman, New York, 1987.]. The technique was first suggested as a suitable representation for GIS in the early 1980s when the two strands were brought together and a tesseral arithmetic applied [F.C. Holdroyd, The Geometry of Tiling Hierarchies, Ars Combanitoria 16B (1983) 211–244.; S.B.M. Bell, B.M. Diaz, F.C. Holroyd, M.J.J. Jackson, Spatially referenced methods of processing raster and vector data, Image and Vision Computing 1 (4) (1983) 211–220.; Diaz, S.B.M. Bell, Spatial Data Processing Using Tesseral Methods, Natural Environment Research Council, Swindon, 1986.]. Here, we describe how that technique can equally be applied to the analysis of environmental interaction with built forms. The way in which the technique deals with the problems described is first to linearise the three-dimensional (3-D) space being investigated. Then, the reasoning applied to that space is applied within the same environment as the definition of the problem data. We show, with an illustrative example, how the technique can be applied. The problem then remains of how to visualise the results of the analysis so undertaken. We show how this has been accomplished so that the 3-D space and the results are represented in a way which facilitates rapid interpretation of the analysis, which has been carried out.

title Success Strategies for Design Professionals
source New York, McGraw-Hill
summary As consultants with the opportunity to analyze literally hundreds of professional design firms, we have found the search for ideal management methods challenging. Each time we've observed a format that appears to work well for some or many firms, an exception has soon appeared, contradicting what looked like a good rule to follow. For example, some firms do outstanding work organized as project teams, others are very successful with a departmentalized project structure, and still others get good results with a studio format. One of the major puzzles for observers has been finding a relation between the project delivery system used by firms (that is, "how we do our work") and how the organization itself is operated (that is, "how we structure and run the firm"). After years of study and trial and error, a model has begun to emerge that holds promise for creating some order among these issues. At the heart of this model is the recognition that although no one strategy fits all firms, there is a family of understandable principles from which almost any firm of design professionals can devise its own best strategy. We call these the SuperPositioning principles. This book sets forth the theory, a set of master strategies derived from it, and some thoughts on how to put the principles to use. We look forward to further learning in the years ahead from the experience of professionals who apply the principles in their own firms.

summary The workshop is an institution, available for use by the public and established at the Laboratory of Housing in the Art Academy's school of Architecture for a 3 year trial period beginning April 1985. This resumé contains brief descriptions of a variety of representative model projects and an overview of all projects carried out so far, including the pilot projects from 1983 and planned projects to and including January 1987. The Full Scale Model Workshop builds full size models of buildings, rooms and parts of buildings. The purpose of the Full Scale Model Workshop is to promote communication among building's users. The workshop is a tool in an attempt to build bridges between theory and practice in research, experimentation and communication of research results. New ideas and experiments of various sorts can be tried out cheaply, quickly and efficiently through the building of full scale models. Changes can be done on the spot as a planned part of the project and on the basis of ideas and experiments achieved through the model work itself. Buildings and their space can thus be communicated directly to all involved persons, regardless of technical background or training in evaluation of building projects.

summary The School of Architecture at Lund Institute of Technology was augmented by the establishment of the Computer Studio in 1987. As a result the school now has a device for teaching and research in the architects' use of computers. We are now conducting several research projects as well as courses and an education project. The third and fourth years of the education at the school of architecture are arranged as education projects instead of traditional lecturing. The students choose from projects that are organised by different departments at the School of Architecture. The issue is that the students will ask for instruction when felt needed, and that learning will therefore be more efficient. The Computer Studio has conducted such a project during the first half of 1989. We have tried to encourage the students to use our different computers and programs in new and creative ways. One of the issues of the computer project is to teach the students how computers are used at the architects offices today as well as expected future developments. The students shall be acquainted well enough with present and future possibilities to make good choices when deciding upon buying computers for architectural use. Another issue is to develop new ways of making and presenting architecture by using computers. As a group the teachers at the school of architecture have a very restrictive attitude towards the use of computers. We hope that our project will open their minds for the possibilities of computers, and to engage them in the development of new ways to use computers creatively in architecture. An interesting question is if the use of computers will yield different outcomes of he students' work than traditional methods. An object for research is whether the added possibilities of considering different aspects of he design by using a computer will make for higher quality of the results.

summary Many constraint satisfaction problems are combinatorically explosive, i.e. have far too many solutions. Optimization techniques may help in selecting solutions for consideration, but a reasonable measure of optimality is not always at hand. The branch & sample algorithm is presented as an alternative to optimization. If the constraints themselves limit the solution set sufficiently, the algorithm finds all solutions, but otherwise a suitable number of solutions (determined by the user) is generated, such that each new solution has a maximal distance to those already generated. The distance measure used is a so called ultrametric distance expressible in terms of the search tree: solutions are viewed as m-tuples of fixed length, each of whose m decision variables corresponds to a level in the search tree. The distance between two solutions is the number of edges from their leaf nodes to the closest common predecessor node in the tree. For problems whose decision variables depend on each other (as is often the case) the set of solutions generated in this way corresponds well to the intuitive notion of a 'representative sample.' The principles of Branch & Sample are first introduced informally, then the algorithm is developed by stepwise refinement, and two examples of its use are given. A fully tested application-independent implementation of the algorithm in C is given as an appendix

summary The working performance of computers and of numerous online-services today are being decentralized and used in networks. The interpersonal exchange of messages and hence electronic mailflow from one computer to another is gaining an increasing significance with the growth of the numbers of PCs being used. At the same time, new low-cost forms of organization and communications are being created. Message Handling as the term for the exchange of locally independent messages and news goes, is being introduced to the individual working place on a worldwide scale with the powerful PTT-Data Packet Switching Networks and the new communications protocols like the X.400 as well as the public electronic mail servers, which are available via telephone.

title An Evaluation of Programming Languages and Language Features for Engineering Software Development
source International Journal of Engineering with Computers. Springer-Verlag, 1988. vol. 3: pp. 183-199
summary Also published as 'Procedural Programming Languages for the Development of CAD and CAE Systems Software,' in the proceedings of ASME International Conference on Computers in Engineering (1987 : New York, NY). The scope of engineering software has increased dramatically in the past decade. In its early years, most engineering applications were concerned solely with solving difficult numerical problems, and little attention was paid to man- machine interaction, to data management, or to integrated software systems. Now computers solve a much wider variety of problems, including those in which numerical computations are less predominant. In addition, completely new areas of engineering applications such as artificial intelligence have recently emerged. It is well recognized that the particular programming language used to develop an engineering application can dramatically affect the development cost, operating cost. reliability, and usability of the resulting software. With the increase in the variety, functionality, and complexity of engineering software, with its more widespread use, and with its increasing importance, more attention must be paid to programming language suitability so that rational decisions regarding language selection may be made. It is important that professional engineers be aware of the issues addressed in this paper, for it is they who must design, acquire, and use applications software, as well as occasionally develop or manage its development. This paper addresses the need for engineers to possess a working knowledge of the fundamentals of computer programming languages. In pursuit of this, the paper briefly reviews the history of four well known programming languages. It then attempts to identify and to look critically at the attributes of programming languages that significantly affect the production of engineering software. The four procedural programming languages chosen for review are those intended for scientific and general purpose programming, FORTRAN 77, C, Pascal, and Modula-2. These languages are compared and some general observations are made. As it is felt important that professional engineers should be able to make informed decisions about programming language selection, the emphasis throughout this paper is on a methodology of evaluation of programming languages. Choosing an appropriate language can be a complex task and many factors must be considered. Consequently, fundamentals are stressed
