title A Hypermedia Model for Supporting Energy Design in Buildings

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.

title Near- Real-Time Control of Human Figure Models
source IEEE Computer Graphics and Applications. June, 1987. vol. 7: pp. 52-60 : ill
summary Includes bibliography. Animating human figures is one of the major problems in computer animation. A recent approach is the use of dynamic analysis to compute the movement of a human figure, given the forces and torques operating within and upon the body. One of the problems with this technique is computing the forces and torques required for particular motions: this has been called the control problem of dynamic analysis. To develop a better understanding of this problem, an interactive interface to a dynamics package has been produced. This interface, along with a collection of low-level motion processes, can be used to control the motion of a human figure model. This article describes both the user interface and the motion processes, along with experiences with this approach

title A Knowledge-based Approach to Mathematical Design Modeling and Optimization
source engineering Optimization. 1987. vol. 12: pp. 91-115
summary Optimization is a well understood process in design domains. Designers formulate their design problems as single criterion or multicriteria optimization problems and then select an appropriate optimization algorithm to search for the optimal values for the design variables. The formulation and algorithm selection procedures have been considered to be activities which relied on substantive human knowledge. This paper describes a computer system, OPTIMA, which formulates design optimization problems from a pseudo-English description into canonical algebraic expressions. It then recognizes the formulation and selects appropriate algorithm(s) for its solution. Finally, it runs the selected algorithm(s) and sends the results back to the original descriptions. Areas of expert knowledge involved in carrying out the above tasks are identified. Such knowledge is explicitly encoded in the system. The basic philosophy and key features of the system are described and are illustrated with examples

title Innovation and Creativity in Knowledge-based CAD
source Amsterdam: North-Holland, 1987. pp. 435-465
summary The authors examine the creativity of knowledge-based design systems from a narrow information processing perspective. As a property of the design process innovation and creativity can be identified by observing both the quality of the product, and also the characteristics of the process itself. The key theme running through the discussion is the acquisition of knowledge as the key to understanding creativity. This involves not only the ability of a system to acquire knowledge, but also its ability to control its own processes and change its own structure. In order to discuss this view a model of design systems is put forward in which a distinction between interpretative and syntactic subsystems for innovation and creativity is made

summary Architectural design is not a science nor a technology. Architectural design is a praxis of both. It embodies knowledge coming from a large range of varied domains, like policy, culture, economy, environmental science, psychology, ..., but it must be clearly distinguished from Bach. It has little to do with the knowledge development or with a better understanding of physical phenomena. Architectural design is a creative activity generating products that intend to achieve: (-) the fulfilment of individual and social needs; (-) serve certain purposes; (-) in order to change the world. // It is a purposeful activity intervening directly on the built environment in order to intentionally modify it. Therefore, teaching architectural design can reasonably be organized as a training for action and, by contrast, the knowledge attainment becomes a relatively secondary objective.

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.

title Study Drawings in Architectural Design: Applications for CAD Systems

doi https://doi.org/10.52842/conf.acadia.1987.157
summary To guide their future development, research and teaching in computer-aided design must look beyond the technical capabilities of computer systems to establish a theoretical foundation based on known processes in design. This paper suggests that such a theoretical foundation can be derived by analyzing architectural study drawings -- defined as the rough drawings that architects make in the exploratory stages of design -- to determine their epistemelogical properties. The analysis brings forward concepts from a number of disciplines related to the structure of human knowledge to identify five properties of study drawings. Based on these properties, the paper proposes strategies for application to the next generation of research and teaching in CAD systems.

source Proceedings of the 1st European Full-Scale Workshop Conference / ISBN 87-88373-20-7 / Copenhagen (Denmark) 15-16 January 1987, pp. 7-17
summary An often repeated statement of the nature of the result of our general construction activities in general says that any building and environmental arrangement could be seen as a pure experimental product. The building, in this sense, is nothing but one single full-scale experiment started afresh each time, unfortunately, we could add, without the consistent follow-up measures. In view of this way of understanding the building process you might deduce the interest in a more anticipating attitude.and behaviour, namely the mock-up method or the full-scale design process, based on the philosophy that in a situation of uncertainty you had better try before than after. An underlying presumption is, however, that generally there is a lack of knowledge about the consequences by transferring spatial and design ideas from. drawings to one to one realization. A lack of knowledge not only-among lay, people but also among professionals. The mock-up practice can also to the same extent be derived from a pure investigative interest with the aim to virtually analyze general or specific problems in the* relationship man and the built environment, particularly buildings and spatial settings on the micro level. That means the use of the full-scale method for the search for basic design knowledge. In this sense the mock-up activities started in Sweden.

title Unsupervised Dynamic Concurrent Computer-Aided Design Assistant
source Los Angeles: UCLA
summary The increasing capability of computer-aided architectural design systems has strengthened the role that the computer plays in the workplace. Due to the complexity of developing new techniques and research, these systems are undertaken mostly by scientists and engineers without significant architectural input (Willey, 1991). The design concept of these systems may be based on a well-defined and well-understood process, which is not yet realized in architectural design (Galle, 1994). The output of such research may not be easily adapted into the design process. Most of the techniques assume a complete understanding of the design space (Gero and Maher, 1987) (Willey, 1991). The description or construction of the design space is always time and space consuming, and the result can never be complete due to the ever-changing nature of architectural design. This research intends to initiate a solution for the above problems. The proposed system is an unsupervised-dynamic-concurrent-computer-aided-design assistant. The “unsupervised” means the learning process is not supervised by the user because it is against the designer's nature to “think-aloud” in the design studio and it also increases the work load. It is dynamic because the size of the knowledge base is constantly changing. Concurrent means that there are multiple procedures active simultaneously. This research focuses on learning the operational knowledge from an individual designer and reapplying it in future designs. A computer system for this experiment is constructed. It is capable of The preliminary result shows a positive feedback from test subjects. The purpose of this research is to suggest a potent computational frame within which future developments may flourish.

summary --- Also published in Artificial Intelligence Developments and Applications edited by J. S. Gero and R. Stanton, North-Holland Pub. 1988. The combination of a heuristic driven search and a tree systems inference technique to induce context-free design grammars is presented. This is achieved by searching for the most useful interpretations of each design in a sample set and discovering regularities in their tree systems representation. The knowledge induced is represented as an accepting tree systems automation and generative grammar. Examples from the domain of architectural design are given

title BIM and Teaching in Architecture: Current thinking and approaches
source De Luca, F, Lykouras, I and Wurzer, G (eds.), Proceedings of the 9th eCAADe Regional International Symposium, TalTech, 15 - 16 June 2023, pp. 105–115
summary Increasing use of BIM has represented a continuing shift in traditional assumptions on how we navigate the design process. BIM is affording the student the ability to gain a greater understanding of their design ideas via the exploration of scale, spatial organisation and structure, amongst many other design layers, in increasing levels of detail, at the same point in the design process. Architectural education is at a delayed tipping point where architectural students are increasingly looking towards BIM to streamline their design process drawn by the production of realistic visualisation, but with a lack of knowledge and skill in its application. With a lack of guidance and understanding around the application of BIM, the use of BIM in this manner overlooks the potential of BIM to construct and test virtual simulations of proposed schemes, to support design enquiry. A historical concern for the pedagogy constructed around the students’ design process is the application of methods and techniques that support the progression through the design process, (Ambrose, 2014; dash mei & Safari, 2018). This study examines the design process of architectural students and the interaction between analogue and digital methods used in design. These primary modes of communication, offer the opportunity to query the roles and rules of traditional architectural conventions around ‘problem finding’ and ‘problem solving’, challenging the ‘traditional’ design process examined by pioneers like Bruner (1966) and Schon (1987). These approaches are distilled from the findings of the study and presented as guidance to those teaching in architectural aBIMemia to align pedagogic goals to methods of abstraction in this new era of design education reconsidering digital methods in design.

title The Computer Model "BGRAF": A Cognitive Approach to Emergency Egress Simulation
source University of Michigan
summary During the past decade, fire safety researchers have come to the understanding that human factors in fires play an important role in controlling the spread of fire; and in decreasing the number of fire casualties in buildings. With the current developments in computer technology, computer modeling of human behavior in fires emerged as an effective method of research. Such computer modeling techniques offered the advantage of being able to experiment with hypothetical fires in buildings without Note endangering human life. Consequently, a study to develop a computer model that will simulate the emergency egress behavior of people in fires was undertaken. Changes in the information processing capacity of the individual as a result of time pressure and stress was considered as part of the emergency egress decision process. Theories from environmental psychology identified a range of cognitive factors, such as visual access in buildings, architectural differentiation, signage and plan configuration that affect way finding and route selection in buildings. These factors needed to be incorporated into emergency egress models. The model was based on the integrated building data base of the CAD system developed at the University of Michigan, Architecture and Planning Lab., which provided a comprehensive building definition, and allowed both graphic and tabular output. Two actual fire incidences were simulated as part of the validation study. These studies have stressed the importance of the cognitive aspects of the physical environment as a factor in emergency egress. A goal structure that represented the total decision process during fires was incorporated into the model. This structure allowed the inputting and testing of a variety of goal structures by using actions as model blocks. The objectives of the model developed in this study can best be summarized as to study and eventually to predict the route selection and exiting behavior in fires, with the purpose of using such information in making building design and code development decisions, and in suggesting action sequences that will best support the safety of the occupants of a building under different emergency conditions.

title A Knowledge-Based Approach to Engineering Information Retrieval and Management
source London, UK: Chapman and Hall Ltd., 1987. pp. 267-295
summary Building design, construction, operation, maintenance, and control are all processes that have achieved various levels of computer use. Although the degree of computerization varies significantly, one common aspect of the computing needs of each process is an abundance of data in the form of tables, standards, project definition information, catalogs, etc. In most cases this data is stored in files which are independently used for input to stand-alone single-process application programs, such as a structural analysis application. The utility of these independent files is therefore limited to a single application. As concepts of integration of engineering applications evolved, the use of databases and database management systems (DBMS) increased. A number of issues of significant concern emerged. First, there is a need to retrieve data from many independent, possibly widely distributed databases. Second, there is a need for a uniform means of doing so. Third, such databases routinely undergo dynamic change. Changes in a database schema commonly result from the evolution of a design, from changes in the design process itself, and from changes in other subsequent downstream processes. Such continuing changes must be reflected in the database schemas and they subsequently require that application programs be updated and that online users be educated on a continuing basis. This chapter describes a knowledge-based expert system that provides access to and integration of the many underlying databases needed to support the building design/construction process. The unique aspect of the expert system presented in this chapter is its capture of the knowledge that an experienced human user incorporates in his search for data in a database, i.e., it seeks to identify and use the generic knowledge needed to operate a DBMS to retrieve data. This knowledge is used by the interface to enable both the online users and the application programs to request data without knowing the data's location or precisely how to ask for it. Further, the interface makes use of mechanisms that allow the user to request data without knowing the exact name by which it is stored in the database. In doing so it formalizes the levels of complexity of that knowledge and points out the multidisciplinary applications of the research results

summary My point of departure is a long standing interest in close human communication. I have been much interested in the multiplicities of communicative levels between persons sharing daily life, e.g. spouses in a household. In the mid-sixties I was working with the first videotapings of marital dyads in a laboratory setting. The "interplay- analysis" which I developed at that time, however, was hampered by the lack of contextual naturalism in the setting. Since - working in the field of "altered states of consciousness" - I came to question the adequacy of studies of extra-ordinary states, in view of the lacking methodology for dealing even with the ranges of the variable ordinary states of mind over the 24-hour cycle in everyday life, and their potential relation to the micro-structure of the habitual ongoing activities of members of a household.
