title	Precedents: Memory Structure in Design Case Libraries
source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 273-287
summary	The paper presents an approach to a memory structure of design ideas in a library of design precedents. A model of case memory for design is developed. The model is composed of distinct chunks of knowledge called design stories. A formalism for the design story is proposed which represents the linkage between design issue, concept and form in stories. Stories are structured in memory according to a semantic network. The lexicon of the semantic network acts as a memory index. The memory structure and indexing system are demonstrated to enhance search and to support crosscontextual browsing and exploration in the precedent library. The approach is demonstrated in a pilot design aid system in the task domain of early conceptual design in architecture.

title	Case-Based Reasoning
source	San Mateo, CA:Morgan Kaufmann
summary	Case-based reasoning systems store information about situations in their memory. As new problems arise, similar situations are searched to help solve them. The author places special emphasis on applying case-based reasoning to complex real-world problem- solving tasks such as medical diagnosis, design, conflict resolution, and planning. The approach combines cognitive science and engineering, and is based on analysis of both expert and common- sense tasks. Guidelines for building case-based expert systems are provided.

summary	Major metropolitan areas and constituent independent jurisdictions face the problem of providing efficient transportation for their residents and in-and out commuters. A typical trip taker spends considerable time on the road to reach the workplace and other destinations. Though it may seem counter-intuitive, adding more links to existing road networks and/or increasing traffic capacity by adding lanes does not necessarily decrease travel times (eg. Braess' paradox). But it is certain that a dense redundant network of roads would provide a trip taker with alternate routes when traffic incidents occur. These types of questions raise the question of, how to evaluate the flow characteristics of the entire road network of a jurisdiction and its larger region in keeping the traffic moving? Further, how may the impact of adding more links/ lanes or the blocking of existing links! lanes be best measured? To answer these and related questions, we propose a methodology to evaluate a fitness criteria for road networks based on Kauffman's biological NK model (1993). We specify a transportation road traffic flow landscape analogous to the fitness landscape of the NK model. Using the transportation road traffic flow landscape we derive a road fitness index that can be used to evaluate either the entire road network's traffic flows or subparts of such network's traffic flows. We explore the possibility of investigating traffic flow landscapes to search for optimal routes to clear traffic. Finally we describe an approach for applying the theoretical framework developed in the paper to the traffic conditions on the road network of the city of Fairfax, Virginia.

title	Open Simulation Environments: A “Preference-Based” Approach
source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 195-214
summary	This paper introduces in conceptual, algorithmic and implementation terms, the notion of an "open" simulation environment as a "multidirectional" approach to computer-aided performance modelling. A "preference- based" formalization of design intentions/criteria is proposed to cope with the "ambiguity" problem through dynamic control of degrees of freedom of relevant design-related parameters during the interactive design process. A prototypical realization of an open simulation environment called "GESTALT' for simultaneous treatment (parametric manipulation) of various design and performance variables is demonstrated. Some preliminary results of computer-assisted generation of performance-responsive designs are presented.

title	Grow: Generative Responsive Object for Web-based design - Methodology for generative design and interactive prototyping
doi	https://doi.org/10.52842/conf.ecaade.2014.2.587
source	Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 2, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 587-594
summary	This paper is part of the research on Generative Design and is inspired by the ideas spread by the following paradigms: the Internet of Things (Auto-ID Center, 1999) and the Pervasive/Ubiquitous Computing (Weiser, 1993). Particularly, the research describes a number of case studies and, in detail, the experimental prototype of an interactive-design object: “Grow-1”. The general assumptions of the study are as follows: a) Developing the experimental prototype of a smart-design object (Figure 1) in terms of interaction with man, with regard to the specific conditions of the indoor environment as well as in relation to the internet/web platforms. b) Setting up a project research based on the principles of Generative Design.c) Formulating and adopting a methodology where computational design techniques and interactive prototyping ones converge, in line with the principles spread by the new paradigms like the Internet of Things.

title	PARADISE: An Intelligent CAD System architecture
source	The Int. Journal of Construction IT 1(3), pp.1-24
summary	This paper presents the architecture of an intelligent CAD system called PARADISE. The motivation is in addressing the lack in architectural computing that has to do with intelligent assistance of design at the early stages. A schema for representing and integrating design knowledge and graphical data called the Design Model (DM) is presented. Following which, work done in developing the CAD-based front end of PARADISE called the graphic subsystem (PGS) is described. The emphasis is at providing tools which facilitate the creation and manipulation of form and spaces at early design stages. We then describe the functionalities of our geometric reasoner (PGS) is described. The geometric reasoner is responsible for all reasoning between the syntax of design drawings and its related semantics. We highlight, in particular, the reasoning of implicit spaces.

summary	The application of computer--based technique to support architectural design has often concentrated on matters of representation. Typically, this means computer-aided drafting, and less frequently, computer-aided modeling and visualization. The promise of new computer-based tools to support the process of design has thus far failed to produce any significant tool that has had a widespread impact on the architectural profession. Most developments remain in university based research labs where they are used as teaching instruments in CAD courses or less often in design studios. While there are many reasons for this lack of dissemination, including a reluctance on the part of the architectural profession itself, the primary obstacles deal with difficulties in explicating design knowledge, representing this knowledge in a manner that can be used for design, and providing an intuitive and effective user interface, allowing the designer to easily use the tool for its intended purpose. This study describes a system that has been developed to address a number of these issues. Based on research findings from the field of Artificial Intelligence which expounds on the need for multiple techniques to represent any complex area of knowledge, we have selected a particular approach that focuses on multiple techniques for design representation. We review this approach in depth by considering its many facets necessary when implementing a knowledge-based system. We then partially test the viability of this approach through a small case study, implementing a knowledge-based system for designing stairs. While this effort only deals with a small part of the total design process, it does explore a number of significant issues facing the development of computer-based design assistants, and suggests several techniques for addressing these concerns.

title	Analogy, Exploration and Generalization: Three Activities for Knowledge-Based Architectural Design Systems
source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 255-272
summary	We propose in this article a system architecture based on reasoning through analogy with past cases or situations. Starting with a project and a sketch provided by the user, the system locates analogous situations in the past and uses these to improve a problem's description. A sufficiently improved description will in turn activate a constraint-satisfaction mechanism. Previous situations are stored in a memory bank of objects that match the description of past problems to the generic descriptions of past solutions. Three mechanisms can be distinguished within the system: an analogy mechanism collects hypotheses about the variables and constraints to be satisfied in past situations, an exploratory mechanism searches through the solution space, a generalizing mechanism looks at experiences and memorizes only what is needed to collect hypotheses.

source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 405-421
summary	The integrated design, construction, and management of buildings are described as being of unlimited complexity. The data structures required to support these tasks cannot be predefined and have- to be worked out during the design process. An instrument that integrates weakly and strongly structured data is necessary. A4 proposes - as a minimal structuring mechanism - the position of information in a dataspace. It offers diverse additional and optional structuring mechanisms. Examples from different domains show the particular strengths of the A4 integration model.

title	Case-Based Structural Design - using weakly structured product and process information
source	Chalmers University of Technology, Division of Steel and Timber Structures, Publ. S 00:7, Göteborg
summary	Empirical knowledge plays a significant role in the human reasoning process. Previous experiences help in understanding new situations and in finding solutions to new problems. Experience is used when performing different tasks, both those of routine character and those that require specific skill. This is also the case for structural designers. Over 50% of the work done by the designer on a day-to-day basis is routine design that consists of modifying past designs (Moore 1993). That is, most of the design problems that the designer solves have been solved before, in many cases over and over again. In recent years, researchers have started to study if cases (information about specific problem-solving experiences) could be used as a representation of experiential knowledge. Making use of past experience in the form of cases is commonly known as Case-Based Reasoning (CBR). A requirement for Case-Based Design (Case-Based Reasoning applied in design) to be successful is that the design information is computerized. One information type used in structural design that is starting to become computerized is the one in design calculation documents. Such information is weakly structured (which holds for much of the information representing experience) and it contains both product and process information. In this thesis it is shown how the weak structure of this information can be used to subdivide it into components, which in turn makes it possible to apply the object-oriented abstraction principles also to this kind of information. It is also shown how the detailed design process can be represented and how this representation can facilitate automatic acquisition, retrieval of relevant old design information, and adaptation of this information. Two prototypes BridgeBase and ARCADE have been developed, where the principles described above are applied. Using ARCADE, the more general of these two prototypes, it is presented how information in computerized design calculation documents, gathered from real projects, can serve as containers and carriers for both project information and experience. The experience from the two prototypes shows that Case-Based Design can be usable as a tool for structural engineers.

source	Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 256-261
summary	Idea association is an important behavior to generate diverse ideas during brainstorming. Through three linking principles (similarity, contrast and contiguity), idea association involves a dynamic linking process between ideas and design cases. Based on the knowledge representation issue-concept-form proposed by Oxman (1993), three interactive patterns between ideas and design cases are investigated. Finally, some computational mechanisms for supporting the linkage of idea association are discussed.

summary	IPER (hypertext for the knowledge of building patrimony) is the result of a research developed with C.N.R. (National Research Institute). The aim of IPER is to provide the knowledge, the description and the management of one or more historical buildings for public or private institutions. IPER allowed us to improve our methodology of building analysis, covering various disciplinary fields, in two different systems. (1.) the first one, synthetic and suitable for a group of historical buildings, (2.) the second one, complex and particularly made for monumental buildings. // This experience is related to the new regulation of teaching architecture in Italy made in 1993. The main novelty is the introduction of the laboratories with the contemporary presence of two or three teachers of different disciplines, working together with the students on the same project with different approaches. This opportunity allowed us to introduce the "knowledge engineer" as a teacher in the laboratory of building technology. IPER is given to the students with the aim of experimenting and solving the theoretical and practical difficulties that students of different years may encounter in the knowledge and representation of buildings and in the organisation of all the data from the case study.

title	The Evolution of an Interface for Choreographers Evolving Design
source	Proceedings of ACM INTERCHI'93 Conference on Human Factors in Computing Systems 1993 pp. 115-122
summary	This paper describes the evolution of the interface to Life Forms, a compositional tool for the creation of dance choreography, and highlights some of the important lessons we have learned during a six year design and implementation period. The lessons learned can be grouped into two categories: 1) Process, and 2) Architecture of the Interface. Our goal in developing a tool for choreography has been to provide computer-based creative design support for the conception and development of dance. The evolution was driven by feedback from the choreographers and users who were members of the development team, combined with our knowledge of current thinking on design and composition. Although the interface evolved in a relatively unconstrained way, the resulting system has many of the features that theoretical discussion in human interface design has projected as necessary. The Life Forms interface has evolved incrementally with one major discontinuity where adoption of a new compositional primitive required a completely new version. The choreography and composition of a dance is a complex synthesis task which has much in common with design. Thus, the lessons learned here are applicable to the development of interfaces to such applications as computer aided design.

title	Exploring Structural Morphology Using CAD
doi	https://doi.org/10.52842/conf.ecaade.1993.x.d1k
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
summary	Often in the design process the student's imagination is restricted by their inability to visualise, model or accurately sketch ideas for innovative structural systems. By using CAD as a design tool it is possible to explore the morphology of complex structures and to be able to produce perspective drawings of them with relative ease. Within AutoCAD there is a small library of standard three-dimensional objects and surfaces that can be called upon to generate more complex forms. However, to further facilitate the architectural design process, an extended library of innovative structural forms would allow the professional designer, or student, greater design freedom and any increase in the palette of structural forms available should stimulate creativity. As practical examples, the paper describes how students have been encouraged to experiment with the use of structures which can only be physically modelled with difficulty and which are also difficult to represent on the two- dimensional surface of the drawing board unless the geometry has previously been determined by the methods described. These are (i) Reciprocal Frame three-dimensional beam grillage structures and (ii) plate domes created from lattice structures by point-to- plane duality. The problem, of representation of these structures has been overcome, in the first case, by generating AutoLISP procedures to draw the complex three-dimensional geometrical form automatically in AutoCAD and, in the second case, by the development of the computer program CADual.

title	Component-Based, Three-Dimensional "Working Drawings"
doi	https://doi.org/10.52842/conf.acadia.1993.141
source	Education and Practice: The Critical Interface [ACADIA Conference Proceedings / ISBN 1-880250-02-0] Texas (Texas / USA) 1993, pp. 141-151
summary	It is now possible to communicate technical information about a building utilizing accurate threedimensional computer modeling of component assemblies of an entire building for the production of an alternative set of "working drawings." Most assembly illustrations and final appearance can be presented as output from the computer model. The use of these three-dimensional images in the practice of architecture may improve communication between the members of the building design team and, therefore, may improve the overall design integration of the various systems in a building. Additionally, this type of component model construction for the production of technical drawings offers a unique bridge over the gap between the practice of architecture and the teaching of architecture. Rather than teaching students how to "do working drawings," something all practitioners wish the academic institutions did, students would develop the ability to design, integrate, and construct complex three-dimensional assemblies and present them in a variety of ways using the standard sections, layers, view, etc. inherent in any reasonable threedimensional computer based modeling system.

title	A Tool for Conceptual Design Evaluation Based on Compliance with Site-Development Briefs and Related Planning Regulations
doi	https://doi.org/10.52842/conf.ecaade.1993.x.c6i
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
summary	The need has been established for a computer based decision support tool to use during the conceptual stages of architectural design. The main functions are to check design compliance with the requirements of local planning authorities; characteristics evaluated will include building size, height, plot ratios, circulation and accessibility, and the preservation of natural features on site. This tool is being developed to operate under AutoCAD environment; the construction industry standard computer aided design software, following standard layering convention, integrated command lines, and pull-down menus. In addition to the common graphical output; i.c. plans, elevations and three dimensional models, it will generate textual analysis in report format to use as part of the Environmental Impact Analysis of proposed development. The tool's functions will be based upon the result of two types of field studies. First, interviews and questionnaires will be carried out with architects and planners of both private and public sectors. These will cover issues related to the performance of Computer Aided Architectural Design applications with regard to the evaluation of design schematics, and decision-making for the production of data for environmental statements. Second, field observation and participation will be carried out to observe decision-makers behaviour during assessment of building design proposals. A prototype is currently under development and will be tested against the expectations of the tool designer, Ashraf Ismail, and a team of professionals to be involved in the field studies. A critical analysis of the prototype design methodology and the study findings will be documented in the research thesis to be presented in June 1995.

doi	https://doi.org/10.52842/conf.ecaade.1993.x.h2e
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
summary	The main objective of this paper is to explain the process of knowledge acquisition utilising the method for the decomposition of the components of a system to extract design rules. The furnished drawing of a dwelling is considered as the language of a designer. These drawings contain the semantic knowledge that can be called general architectural know-how. This paper bases on the decomposition of the syntax of a room image. The syntax of a room image consists of walls, windows, circulation zones and furniture such as beds, wardrobes, commodes, dressing tables, etc. The syntax of a room image has some linkages. The designer put the syntax together with the joints of circulation zones as a grammar to match. The existing relations between the objects in a design can be called grammar. An experiment is applied to three classes of a CAAD course organised by the Turkish Chamber of Architects. The living room is given already furnished in the experiment and the rest of a dwelling is expected to be furnished. In the first phase, the experiment is applied on two different classes in different times. It is interesting that the same grammar is used by 6 of 8 couple of designers for 3 different types (A, B and D) of bedrooms. Only one of the bedrooms of C type) has different design styles in spite of looking much like each other. In the second phase, for the third class of 6 groups, plan is modified slightly. In this case all of the 6 couples of designers use the same grammar for 2 alternatives of D type bedroom for parents. An original method is applied in the elicitation of the knowledge in this experiment. The properties of the objects and their links are represented by a semantic network graph. This paper also presents the grammar of the furnished rooms and shows the density of preferences. Design rules are extracted from these drawings of a furnished dwelling by searching for similarities in the plans designed by different designers. The designers have some specifications about the grammar of furnishing and an image schema of the proposed room in their minds, depending on their education and experiences. During the design of a room, designers look for differences and the similarities existing in the syntax of the proposed room image and the image of furnished room on the screen. If these images match with each other, the designers satisfy with the result This paper investigates the image schemata of the designers by evaluating their drawings. Some design rules are represented by means of image schemata. Matching the joints of circulation zones, the designers put the syntax of different image schemata together and they can illustrate different alternatives, restricted by the translation of these image schemata.

summary	In this paper, we describe work on a CAD package we are developing for use in virtual reality. Although this research is only preliminary, it demonstrates some advantages of designing in virtual reality. We describe these advantages in terms of ecological approach to perception, focusing on two of the implications of this approach: the role of perception-action coupling in producing true direct manipulation, and the desirability of providing perceptual information about the affordances of objects in the design environment.

title	Comparative Evaluation of Four Daylighting Software Programs
source	1998 ACEEE Summer Study on Energy Efficiency in Buildings Proceedings. American Council for an Energy-Efficient Economy
summary	By the mid-1980's, a number of software packages were under development to predict daylighting performance in buildings, in particular illumination levels in daylighted spaces. An evaluation in 1988 by Ubbelohde et al. demonstrated that none of the software then available was capable of predicting the simplest of real daylighting designs. In the last ten years computer capabilities have evolved rapidly and we have four major packages widely available in the United States. This paper presents a comparative evaluation from the perspective of building and daylighting design practice. A contemporary building completed in 1993 was used as a base case for evaluation. We present the results from field measurements, software predictions and physical modeling as a basis for discussing the capabilities of the software packages in architectural design practice. We found the current software packages far more powerful and nuanced in their ability to predict daylight than previously. Some can accurately predict quantitative daylight performance under varying sky conditions and produce handsome and accurate visualizations of the space. The programs differ significantly, however, in their ease of use, modeling basis and the emphasis between quantitative predictions and visualization in the output.
