title	Toward a procedure of computer simulation in the restoration of historical architecture
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	In the field of architectural design, “visualization¨ generally refers to some media, communicating and representing the idea of designers, such as ordinary drafts, maps, perspectives, photos and physical models, etc. (Rahman, 1992; Susan, 2000). The main reason why we adopt visualization is that it enables us to understand clearly and to control complicated procedures (Gombrich, 1990). Secondly, the way we get design knowledge is more from the published visualized images and less from personal experiences (Evans, 1989). Thus the importance of the representation of visualization is manifested.Due to the developments of computer technology in recent years, various computer aided design system are invented and used in a great amount, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and collaboration, etc. (Lawson, 1995; Liu, 1996). The conventional media are greatly replaced by computer media, and the visualization is further brought into the computerized stage. The procedure of visual impact analysis and assessment (VIAA), addressed by Rahman (1992), is renewed and amended for the intervention of computer (Liu, 2000). Based on the procedures above, a great amount of applied researches are proceeded. Therefore it is evident that the computer visualization is helpful to the discussion and evaluation during the design process (Hall, 1988, 1990, 1992, 1995, 1996, 1997, 1998; Liu, 1997; Sasada, 1986, 1988, 1990, 1993, 1997, 1998). In addition to the process of architectural design, the computer visualization is also applied to the subject of construction, which is repeatedly amended and corrected by the images of computer simulation (Liu, 2000). Potier (2000) probes into the contextual research and restoration of historical architecture by the technology of computer simulation before the practical restoration is constructed. In this way he established a communicative mode among archeologists, architects via computer media.In the research of restoration and preservation of historical architecture in Taiwan, many scholars have been devoted into the studies of historical contextual criticism (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000). Clues that accompany the historical contextual criticism (such as oral information, writings, photographs, pictures, etc.) help to explore the construction and the procedure of restoration (Hung, 1995), and serve as an aid to the studies of the usage and durability of the materials in the restoration of historical architecture (Dasser, 1990; Wang, 1998). Many clues are lost, because historical architecture is often age-old (Hung, 1995). Under the circumstance, restoration of historical architecture can only be proceeded by restricted pictures, written data and oral information (Shi, 1989). Therefore, computer simulation is employed by scholars to simulate the condition of historical architecture with restricted information after restoration (Potier, 2000). Yet this is only the early stage of computer-aid restoration. The focus of the paper aims at exploring that whether visual simulation of computer can help to investigate the practice of restoration and the estimation and evaluation after restoration.By exploring the restoration of historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example), this study aims to establish a complete work on computer visualization, including the concept of restoration, the practice of restoration, and the estimation and evaluation of restoration.This research is to simulate the process of restoration by computer simulation based on visualized media (restricted pictures, restricted written data and restricted oral information) and the specialized experience of historical architects (Potier, 2000). During the process of practicing, communicates with craftsmen repeatedly with some simulated alternatives, and makes the result as the foundation of evaluating and adjusting the simulating process and outcome. In this way we address a suitable and complete process of computer visualization for historical architecture.The significance of this paper is that we are able to control every detail more exactly, and then prevent possible problems during the process of restoration of historical architecture.

title	Computational Design Instruction: Toward a Pedagogy
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. 302-316
summary	The computer offers enormous potential both in and out of the classroom that is realized only in limited ways through the applications available to us today. In the early days of the computer it was generally argued that it would replace the architect. When this idea became obsolete, the prevailing opinion of proponents and opponents alike shifted to the notion of the computer as merely adding to present design capabilities. This idea is so ingrained in our thinking that we still speak of "aiding" design with computers. It is clear to those who grasp the real potential of this still new technology - as in the case of many other major technological innovations - that it continues to change the way we design, rather than to merely augment or replace human designers. In the classroom the computer has the potential to radically change three fundamental ingredients: student, instruction, and instructor. It is obvious that changes of this kind spell out a commensurate change in design pedagogy. If the computer is going to be more than a passive instrument in the design studio, then design pedagogy will have to be changed, fundamentally. While the practice of computing in the studio continues to be a significant I aspect of architectural education, articulation of viable pedagogy for use in the design studio is truly rare. In this paper the question of pedagogy in the CAD studio will be considered first. Then one particular design studio taught during Fall 1988 at Carnegie Mellon University will be presented. Finally, we shall return to issues of change in the student, instruction, and instructor, as highlighted by this particular experience.

title	Expert Systems for Detail Design in Building
source	CAAD futures ‘87 [Conference Proceedings / ISBN 0-444-42916-6] Eindhoven (The Netherlands), 20-22 May 1987, pp. 117-126
summary	Computer-Aided Architectural Design (CAAD) requires detailed knowledge of the construction of building elements to be effective as a complete design aid. Knowledge-based systems provide the tools for both encapsulating the "rules" of construction - i.e. the knowledge of good construction practice gained from experience - and relating those rules to geometric representation of building spaces and elements. The "rules" of construction are based upon the production and performance implications of building elements and how these satisfy various functional criteria. These building elements in turn may be related to construction materials, components and component assemblies. This paper presents two prototype knowledge-based systems, one dealing with the external envelope and the other with the internal space division of buildings. Each is "component specific" and is based upon its own model of the overall construction. This paper argues that "CAAD requires component specific knowledge bases and that integration of these knowledge bases into a knowledge-based design system for complete buildings can only occur if every knowledge base relates to a single coordinated construction model".

title	Engaging Intuitive Visual Thinking in Urban Design Modelling: A Real-Time Hypothesis
source	Computing in Design Education [ACADIA Conference Proceedings] Ann Arbor (Michigan / USA) 28-30 October 1988, pp. 87-97
doi	https://doi.org/10.52842/conf.acadia.1988.087
summary	This paper will present prototypical software being used in the teaching of urban design to students and for use by professionals in the early stages of a project. The system is intended to support a heuristic approach to design. That is, it supports a process of refining ideas and understandings through a process of trial and error. The support or aid to design comes in the form of a didactic real-time programme. Its power lies in its ability to provide instantaneous response to operations on the data that can allow one to develop threedimensional spatial ideas in an intuitively driven manner. This condition appears to occur for both novice and expert computer operators. The presentation will present our experience to-date in using conventional computer graphic tools to represent design ideas and contrast it with a video demonstration of our prototypical dynamic urban design modelling software for the Silicon Graphics IRIS computers.

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	Expert systems in Engineering Design : the Concept of Prototypes and their Application
source	Symposium on Knowledge Based Systems in Civil Engineering. 1988. pp. 37-45
summary	CADLINE has abstract only. This paper addresses the question of what sort of schemata do experts in engineering design use to allow the commencement and continuation of a design. It is suggested that a conceptual schema labelled prototype can be used to capture this expertise. Prototypes are generalizations at different levels of design experience and provide the bases of an approach to designing with computers. They structure design experience to make it applicable in similar situations. The paper elaborates the concept and briefly describes an application

summary	The formation of our vision for a computer-integrated design studio is outlined. The ways in which our experience in teaching with computers in a variety of settings and in developing our own computer tools has contributed to this is explained. The next step in actualization of our vision is the creation of a design curriculum and a computerized studio which support the integration of this new technology into the traditions of architectural education.

summary	The development planning of the full-scale laboratory at the Vienna University of Technology was already presented to the third E.F.A. Conference in Lund (1990). Exchange of experience has greatly encouraged us to take all measures necessary for an immediate provisional operation. Working experience was of considerable significance regarding reconstruction work having repeatedly been postponed ever since 1988. This paper deals with the Vienna full-scale laboratory in its ultimate form and all the equipment designed therefore. Summarizingly, the further measures for operation are being considered.

title	SOLAREXPERT : A Prototype Expert System for Passive Solar Energy Design in Housing
source	Canberra: Aust NZ Solar Energy Society, 1987. vol.II: pp. 361-370. Also published in People and Technology - Sun, Climate and Building, edited by V. Szokolay, Univ. of Queensland, Brisbane, 1988
summary	Passive solar energy design is not an exact science in which a set of analytical procedures can be followed to produce results. Rather it depends heavily on subjective parameters and experience collected over time which is heuristic by nature. At present this knowledge is available in books but while this knowledge is comprehensive, it is unstructured and not always easy to make use of. A computer-based system allows for flexible interactive dialogue and for the incorporation of analytical procedures which may be required. This paper describes work on SOLAREXPERT, a prototype expert system to aid designers in passive solar energy design for single dwellings. The system operates at a strategic level to provide basic advice on the form of construction and types of passive solar systems and at a spatial zone level to provide more detailed advice on sizes and materials. It allows for modification of the information entered so that users may explore several possibilities

summary	--- Also printed in 1989 Civil Engineering Systems 6(1&2):11-20. Engineering is concerned with much more than calculation and numeric analysis. It is concerned with ideas, concepts, judgement and deploying experience which cannot be represented numerically. All of these appear to be outside the realm of traditional engineering computing. Engineers make use of knowledge about objects, events and processes and make declarative statements about them which are often written down symbolically. These limitations of traditional computing in civil engineering can be overcome by expert systems. In this paper a number of expert systems dealing with analysis, design and knowledge acquisition in the field of civil engineering are presented

doi	https://doi.org/10.52842/conf.acadia.1988.035
summary	Recent research at the Corps of Engineers Construction Engineering Research Laboratory (CERL) investigated embedded computer-based instruction for AutoCAD. The results of this study, which are the focus of this paper, indicated that the only factor which correlated with success in completing the final test was previous experience with another CAD system. Those who knew another CAD system had higher scores and required less than half the time to complete the lessons. Presumably their conceptual knowledge about CAD transferred to the new software environment, even though the Corps' study showed that they were initially biased against learning the new system. Such biased attitudes have been observed when users are asked to learn a second similar software of any kind. Architects who are deeply involved in computer-aided design have stated that one must learn to program the computer to build the conceptual framework for the creative process. We at CERL agree that an understanding of underlying graphics concepts is essential to the designer. Our research shows that giving students the freedom to explore an existing software program can result in the development of conceptual knowledge. Interviews also reveal that students can invent ways to meet individual objectives when "guided discovery" learning is encouraged.

title	The Application of Cognitive Psychology to CAD Input/Output
source	Proceedings of the HCI'88 Conference on People and Computers IV 1988 p.477-488
summary	The design of usable human-computer interfaces is one of the primary goals of the HCI specialist. To date however interest has focussed mainly on office or text based systems such as word processors or databases. Computer aided design (CAD) represents a major challenge to the human factors community to provide suitable input and expertise in an area where the users goals and requirements are cognitively distinct from more typical HCI. The present paper is based on psychological investigations of the engineering domain, involving an experimental comparison of designers using CAD and the more traditional drawing board. By employing protocol analytic techniques it is possible to shed light on the complex problem-solving nature of design and to demonstrate the crucial role of human factors in the development of interfaces which facilitate the designers in their task. A model of the cognition of design is proposed which indicates that available knowledge and guidelines alone are not sufficient to aid CAD developers and the distinct nature of the engineering designer's task merits specific attention.

source	Reconnecting [ACADIA Conference Proceedings / ISBN 1-880250-03-9] Washington University (Saint Louis / USA) 1994, pp. 39-49
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.

title	Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
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. 247-264.
summary	The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called ‚Äúgingerbread houses‚Äù, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

title	Concept Design Games
source	Design Studies, Volume 9, Number 3, 1988, pp. 12-23
summary	This paper describes our work on using games as a tool for research in design theory and methods. Games offer a means of isolating certain aspects, or concepts, of designing for purposes of scrutiny. A game provides an environment for a group of players, acting with individual goals and a shared program, to make and transform complex configurations, free of functional requirements. Adjusting game parameters emphasizes different concepts. We have developed nine games that explore a variety of concepts of general interest to those concerned with organizing physical configurations. Beyond these particular concepts, we argue that games are a useful way to couch studies in design theory and methods.

title	A new paradigm for life-cycle management of kit-of-parts building systems
source	UNIVERSITY OF MICHIGAN , PhD
summary	The research described in this dissertation brings together various technologies in manufacturing and information management and suggests a new paradigm for the design, manufacture, and lifetime use of artifacts using kit-of-parts systems and rule-based assembly. The questions are asked: If architects, designers, and users were given direct online connection to real-time design information sources and fabrication processes, and have the ability to monitor and control the current state of designed objects throughout the objects' lifetime, how would the entire life-cycle of a product be affected, and how would design processes change? During the course of the research described in this dissertation, a series of simulations and experiments were conducted which produced a computer-based simulated design, manufacture, and use environment wherein these questions could begin to be answered. A kit-of-parts model building system was devised which could be used to design model buildings in virtual form by downloading virtual representations of the components from the Internet and assembling them into a desired form. The virtual model building could then be used to order the manufacture of real components online, and remotely controlled robots used to assemble the actual building on the site. Through the use of special hardware manufactured into the components, real-time remote monitoring and control of the current state of the finished model building was affected during the building's lifetime. The research establishes the feasibility of an online life-cycle environment where a virtual representation of an artifact is created and used to both manufacture a real-world counterpart and also monitor and control the current state of the real-world object. The state-of-the-art of pertinent technologies were explored through literature searches and experiments. Data representation, rule-based design techniques, robotics, and digital control were studied, and a series of design principles established which lend themselves toward a life-cycle management paradigm. Several case studies are cited which show how the design principles and life-cycle management environment can be applied to real buildings and other artifacts such as vehicles and marine structures. Ideas for expanded research on the life-cycle management paradigm are cited.

title	Seat preference in public squares and distribution of the surrounding people: An examination of the validity of using visual simulation
source	Motion, E-Motion and Urban Space [Proceedings of the 7th European Architectural Endoscopy Association Conference / ISBN-10: 3-00-019070-8 - ISBN-13: 978-3-00-019070-4], pp. 151-163
summary	Public squares are shared by people who use them for various purposes. When people choose seats in a square, they unconsciously evaluate not only the physical characteristics of the space but also the distribution of others already present (Hall, 1966; Sommer, 1969; Whyte, 1988). Knowing the hidden rules of this behaviour will be important in designing squares that remain comfortable even in crowded situations. Most past studies of seat choice preference have reported on statistical tendencies derived from observations of subject behavior in actually existing sites (i.e., Abe, 1997; Imai, 1999; Kawamoto, 2003). However, they provide no clear theoretical model for explaining the basic mechanisms regulating such behaviour. The present study conducts a series of experiments in both real and virtual settings in order to extract quantitative relationships between subjects’ seat preferences and the presence of nearby strangers and to clarify what factors influence their seat choices.
