title	Design Knowledge, Environmental Complexity in Nonorthogonal Space
source	New York: John Wiley & Sons, 1992. pp. 273-291 : ill. includes bibliography
summary	Mechanization and industrialization of society has resulted in most people spending the greater part of their lives in enclosed environments. Optimal design of indoor artificial climates is therefore of increasing importance. Wherever artificial climates are created for human occupation, the aim is that the environment be designed so that individuals are in thermal comfort. Current design methodologies for radiant panel heating systems do not adequately account for the complexities of human thermal comfort, because they monitor air temperature alone and do not account for thermal neutrality in complex enclosures. Thermal comfort for a person is defined as that condition of mind which expresses satisfaction with the thermal environment. Thermal comfort is dependent on Mean Radiant Temperature and Operative Temperature among other factors. In designing artificial climates for human occupancy the interaction of the human with the heated surfaces as well the surface-to-surface heat exchange must be accounted for. Early work in the area provided an elaborate and difficult method for calculating radiant heat exchange for simplistic and orthogonal enclosures. A new improved method developed by the authors for designing radiant panel heating systems based on human thermal comfort and mean radiant temperature is presented. Through automation and elaboration this method overcomes the limitations of the early work. The design procedure accounts for human thermal comfort in nonorthogonal as well as orthogonal spaces based on mean radiant temperature prediction. The limitation of simplistic orthogonal geometries has been overcome with the introduction of the MRT-Correction method and inclined surface-to-person shape factor methodology. The new design method increases the accuracy of calculation and prediction of human thermal comfort and will allow designers to simulate complex enclosures utilizing the latest design knowledge of radiant heat exchange to increase human thermal comfort

title	Shape recognition in three dimensions
source	Environment and Planning B: Planning and Design 19 : 585-603
summary	The subshape recognition problem for three-dimensional shapes under linear transformations is considered. The problem is analysed in a series of cases, some that provide a determinate number of solutions and others that have indeterminately many solutions. Procedures for its solution for general shapes are developed. Difficulties posed by strict adherence to rational transformations are examined. As a corollary, an outline of a procedure for determining the symmetries of a shape is presented. Subject

title	Alternatives to Syntactic Paradigms in CAAD: Using Random Numbers in Layout Generation and Spatial Modeling.
doi	https://doi.org/10.52842/conf.ecaade.1992.497
source	CAAD Instruction: The New Teaching of an Architect? [eCAADe Conference Proceedings] Barcelona (Spain) 12-14 November 1992, pp. 497-510
summary	The paper provides instances of graphic techniques using random numbers in layout generation and spatial modelling. Leaving aside more elaborate methods based on shape grammars and syntactically oriented schemes, direct graphic procedures useful in computer aided architectural design are discussed. Drawings presented show how aleatory input can influence the appearance of computer generated forms.

title	Variational surface modeling
source	Computer Graphics, 26, Proceedings, SIGGRAPH 92
summary	We present a newapproach to interactivemodeling of freeform surfaces. Instead of a fixed mesh of control points, the model presented to the user is that of an infinitely malleable surface, with no fixed controls. The user is free to apply control points and curves which are then available as handles for direct manipulation. The complexity of the surface's shape may be increased by adding more control points and curves, without apparent limit. Within the constraints imposed by the controls, the shape of the surface is fully determined by one or more simple criteria, such as smoothness. Our method for solving the resulting constrained variational optimization problems rests on a surface representation scheme allowing nonuniform subdivision of B-spline surfaces. Automatic subdivision is used to ensure that constraints are met, and to enforce error bounds. Efficient numerical solutions are obtained by exploiting linearities in the problem formulation and the representation.

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	On the Limitations of Shape Grammars: Comments on Aaron Fleisher’s Article “Grammatical Architecture?”
doi	https://doi.org/10.52842/conf.acadia.2003.279
source	Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 279-287
summary	Shape grammars were introduced by Gips and Stiny in 1972. Since then, there have been many articles and books written by them and their associates. In 1992, Aaron Fleisher, a professor at the School of Planning, MIT, wrote a critique of their work in an article titled “Grammatical Architecture?” published in the journal Environment and Planning B. According to him, Gips, Stiny and later Mitchell, propose a hypothesis that states that shape grammars are presumed to represent knowledge of architectural form, that grammars are “formable,” and that there is a visual correspondence to verbal grammar. The strong version of “the hypothesis requires that an architectural form be equivalent to a grammar.” Fleisher considers these hypotheses unsustainable, and argues his case by analyzing the differences between language, and architecture, and by dealing with the concepts of lexicons, syntax and semantics. He concludes by stating that architectural design is negotiated in two modalities: the verbal and the visual, and that equivalences are not at issue; they do not exist. If there is such thing as a language for design, it would provide the means to maintain a discussion of the consequences in one mode, of the state and conditions of the other. Fleisher’s observations serve as the basis of this paper, a tribute to him, and also an opportunity to present an outline to an alternate approach or hypothesis to shape grammars, which is “nonlinguistic” but “generative,” in the sense that it uses production rules. A basic aspect of this hypothesis is that the only similarity between syntactic rules in language and some rules in architecture is that they are recursive.

title	A computer-based framework for analyzing and deriving the morphological structure of architectural designs
source	University of Michigan
summary	An approach to the acquisition and utilization of knowledge about the morphological structure of notable orthogonal building plans and other two-dimensional compositions is formulated and tested. This approach consists of two levels of abstraction within which the analysis and comparison of existing designs and the derivation of new designs can be undertaken systematically and efficiently. Specifically, the morphological structure of orthogonal building plans and other two-dimensional compositions is conceived as a language defined by shape grammar and architectural grammar corresponding to the geometric and spatial structures of the compositions. Lines constitute the shape grammar and walls and columns the architectural grammar. A computer program named ANADER is designed and implemented using the C++ object-oriented language to describe feasible compositions. It is argued that the gap between morphological analysis and synthesis is bridged partially because the proposed framework facilitates systematic comparisons of the morphological structures of two-dimensional orthogonal compositions and provides insight into the form-making process used to derive them. As an analytical system, the framework contributes to the generation of new and the assessment of existing morphological knowledge. Specifically, it is demonstrated that it is feasible to specify an existing architectural design by a set of universal rule schemata and the sequence of their application. As a generative system, the framework allows many of the tasks involved in the derivation of two-dimensional orthogonal compositions to be carried out. As well, it promotes the use of analytical results. In conclusion, it is argued that the proposed computer-based framework will provide the research and the educator with increasing opportunities for addressing persistent architectural questions in new ways. Of particular interest to this author are questions concerning the decision-making activities involved in form- and space-making as well as the description, classification, and derivation of architecutural form and space. It is suggested that, at least in reference to the cases examined, but probably also in reference to many other morphological classes, these and other related questions can be addressed systematically, efficiently, and fruitfully by using the proposed framework.

title	Discontinuity Meshing for Accurate Radiosity
source	IEEE Computer Graphics & Applications, November 1992, pp.25-38
summary	We discuss the problem of accurately computing the illumination of a diffuse polyhedral environment due to an area light source. We show how umbra and penumbra boundaries and other illumination details correspond to discontinuities in the radiance function and its derivatives. The shape, location, and order of these discontinuities is determined by the geometry of the light sources and obstacles in the environment. We describe an object-space algorithm that accurately reproduces the radiance across a surface by constructing a discontinuity mesh that explicitly represents various discontinuities in the radiance function as boundaries between mesh elements. A piecewise quadratic interpolant is used to approximate the radiance function, preserving the discontinuities associated with the edges in the mesh. This algorithm can be used in the framework of a progressive refinement radiosity system to solve the diffuse global illumination problem. Results produced by the new method are compared with ones obtained using a standard radiosity system.

summary	Reasoning is influenced by our perception of the environment. New aspects of our environment help to provoke new thoughts. Thus, changes of what is perceived can be assumed to stimulate the generation of new ideas, as well. In CAD, computerized three-dimensional models of physical entities are produced. Their representation on the monitor is determined by our viewing position and by the rendering method used. Especially the wire-frame representations of views lend themselves to a variety of readings, due to coincident and intersecting lines. Methods by which wire-frame views can be processed to extract the shapes that they contain have been investigated and developed. The extracted shapes can be used as a base for the generation of derived entities through various operations that are called Reinterpretation Operations. They have been implemented as a prototypical extension (named Reint-Ops) to an existing modeling shell. ReintOps is a highly interactive exploratory CAD tool, which allows the user to customize criteria and factors which are used in the reinterpretation process. This tool can be regarded as having a potential to support conceptual design investigations.

title	Computer Aided Design for Wind and Seismic Forces
doi	https://doi.org/10.52842/conf.acadia.1992.187
source	Mission - Method - Madness [ACADIA Conference Proceedings / ISBN 1-880250-01-2] 1992, pp. 187-194
summary	A computer program, Lateral Design Graphs (LDG), to consider lateral wind and seismic forces in the early design stages, is presented. LDG provides numeric data and graphs to visualize the effect of building height, shape, and framing system on lateral forces. Many critical decisions effecting lateral forces and elements to resist them are made at early design stages. Costly changes or reduced safety may result if they are not considered. For example, building height, shape and configuration impact lateral forces and building safety; so does the placement of shear walls in line with space needs. But the complex and time consuming nature of lateral force design by hand makes early consideration often not practical. Therefore the objectives of LDG are to: 1) visualize the cause and effect of lateral forces; 2) make the design process more transparent; 3) develop informed intuition; 4) facilitate trade-off studies at an early stage; 5) help to teach design for lateral forces.

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

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

title	Two Approaches to Teaching Computers in Architecture: The Experience in the Faculty of Engineering in Palermo, Italy
doi	https://doi.org/10.52842/conf.ecaade.1992.295
source	CAAD Instruction: The New Teaching of an Architect? [eCAADe Conference Proceedings] Barcelona (Spain) 12-14 November 1992, pp. 295-306
summary	Teaching the use of computers in architecture poses the same kind of problems as teaching mathematics. To both there are two possible approaches. The first presents the discipline as a tool of which the merely instrumental aspect is emphasized. Teaching is limited to show the results obtainable by existing programs and how to get them. The second approach, on the contrary emphasizes the autonomous nature of the discipline, mathematics as much as computing, on the basis of the convincement that the maximum of instrumental usefulness can be obtained through the knowledge at the highest degree of generality and, then, of abstraction. The first approach changes little in the mind of the student. He simply learns that is possible, and then worthy doing, a certain amount of operations, mainly checks of performances (and not only the control of the aspect, now easy with one of the many existing CAD) or searches of technical informations in some database. The second approach gives the student the consciousness of the manageability of abstract structures of relationships. He acquires then the idea of creating by himself particular structures of relationships and managing them. This can modify the very idea of the design procedure giving the student the consciousness that he can intervene directly in every segment of the design procedure, reshaping it to some extent in a way better suited to the particular problem he is dealing with. Of course this second approach implies learning not only a language but also the capability of coming to terms with languages. And again it is a cultural acquisition that can be very useful when referred to the languages of architecture. Furthermore the capability of simulating on the computer also a small segment of the design process gives the student a better understanding both of the particular problem he is dealing with and of the very nature of design. As for the first effect, it happens whenever a translation is done from a language to another one. One is obliged to get to the core of the matter in order to overcome the difficulties rising from the different bias of the two languages. The second effect comes from the necessity of placing the studied segment in the general flow of the design process. The organisation in a linear sequence of action to be accomplished recursively in an order always varying in any design occasion is an extremely useful exercise to understand the signification and the techniques of formalisation of design problems.

title	A decision-making process for choice of a flexible internal partition option in multi-unit housing using decision theory techniques
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	Recent demographic changes have increased the heterogeneity of user groups in the North American housing market. Smaller households (e.g. elderly, single parent) have non-traditional spatial requirements that cannot be accommodated within the conventional house layout. This has created renewed interest in Demountable/Flexible internal partition systems. However, the process by which designers decide which project or user groups are most suited for the use of these systems is quite often complex, non-linear, uncertain and dynamic, since the decisions involve natural processes and human values that are apparently random. The anonymity of users when mass housing projects are conceptualized, and the uncertainty as to the alternative to be selected by the user, given his/her constantly changing needs, are some contributing factors to this effect. Decision Theory techniques, not commonly used by architects, can facilitate the decision-making process through a systematic evaluation of alternatives by means of quantitative methods in order to reduce uncertainty in probabilistic events or in cases when data is insufficient. The author used Decision Theory in the selection of flexible partition systems. The study involved a multi-unit, privately initiated housing project in Montreal, Canada, where real site conditions and costs were used. In this paper, the author outlines the fundamentals of Decision Theory and demonstrates the use of Expected Monetary Value and Weighted Objective Analysis methods and their outcomes in the design of a Montreal housing project. The study showed that Decision Theory can be used as an effective tool in housing design once the designer knows how to collect basic data.

title	Design support via simulation of building and plant thermal interaction
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	Design decision support related to building energy consumption and/or indoor climate should be based on an integral approach to the environment, the building, heating, ventilating and air-conditioning (HVAC) system, and the occupants. The tools to achieve this are now available in the form of computer simulation systems which treat the building and plant as an integrated dynamic system. Although its potentials reach beyond the area of Computer Aided Building Design, the paper describes building and plant energy simulation within the context of CABD, design decision support and design evaluation. Currently, computer simulation is only used indirectly as a design decision support mechanism; that is, its power is not delivered very efficiently to the design profession. This paper suggests some future research directions. These are aimed at providing a mechanism to overcome this problem by developing an intelligent front end' which bridges the gap between sophisticated computer simulation tools and the design profession.

title	Sculpting the Space: A Circulation Based Approach to Generative Design in a Multi-Agent System
doi	https://doi.org/10.52842/conf.caadria.2014.565
source	Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 565–574
summary	This paper discusses an MAS (multiagent system) based approach to generating architectural spaces that afford better modes of human movement. To achieve this, a pedestrian simulation is carried out to record the data with regard to human spatial experience during the walking process. Unlike common practices of performance oriented generation where final results are achieved through cycles of simulation and comparison, what we propose here is to let human’s movement exert direct influence on space. We made this possible by asking "humans" to project simulation data on architectural surroundings, and thus cause the layout to change for the purpose of affording what we designate as good spatial experiences. A generation experiment of an exhibition space is implemented to explore this approach, in which tentative rules of such spatial manipulation are proposed and tested through space syntax analyse. As the results suggested, by looking at spatial layouts through a lens of human behaviour, this projection-and-generation method provides some insight into space qualities that other methods could not have offered.

summary	This contribution deals with the question, what the simulation in full-scale can convey to the architecture students within their architecture studies. Is it predominantly their independant investigation of architectural space, an aid for decision making regarding their confrontation with "space" as such? Or should the student rather rely on his own imagination? Apart from some exeptions it is the built space that is the subject of all and every planning work, and it is then at the latest that all the advantages and shortcomings are uncovered. Spatial experiments performed is Lausanne in Vienna are introduced, special attention been given to the specific methodical procedure involved.

title	A trichotomic segmentation procedure to evaluate projects in architecture

summary	This paper illustrates a model used to construct the evaluation module for An Interface for Designing (AID), a system to aid architectural design. The model can be used at the end of every cycle of analysis-synthesis-evaluation in the intermediate phases of design development. With the aid of the model it is possible to evaluate the quality of a project in overall terms to establish whether the project is acceptable, whether it should be elaborated ex-novo, or whether it is necessary to begin a new cycle to improve it. In this last case, it is also possible to evaluate the effectiveness of the possible actions and strategies for improvement. The model is based on a procedure of trichotomic segmentation, developed with MCDA (Multi-Criteria Decision Aid), which uses the outranking relation to compare the project with some evaluation profiles taken as projects of reference. An application of the model in the teaching field will also be described.
