title	Image and Shape: Two Distinct Approaches
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 410-415
summary	This paper is the result of two researches done at the district of Campeche, Florianópolis, by the Grupo PET/ARQ/UFSC/CAPES. Different aspects and conceptual approaches were used to study the spatial attributes of this district located in the Southern part of Santa Catarina Island. The readings and analysis of two researches were based on graphic pistures builded with the use of Corel 7.0 e AutoCadR14. The first research – "Urban Development in the Island of Santa Catarina: Public Space Study"- examined the urban structures of Campeche based on the Spatial Syntax Theory developed by Hillier and Hanson (1984) that relates form and social appropriation of public spaces. The second research – "Topoceptive Characterisation of Campeche: The Image of a Locality in Expansion in the Island of Santa Catarina" -, based on the methodology developed by Kohlsdorf (1996) and also on the visual analysis proposed by Lynch (1960), identified characteristics of this locality with the specific goal of selecting attributes that contributed to the ideas of the place its population held. The paper consists of an initial exercise of linking these two methods in order to test the complementarity of their analytical tools. Exemplifying the analytical procedures undertaken in the two approaches, the readings done - global (of the locality as a whole) and partial (from parts of the settlement) - are presented and compared.

title	Generative Housing Communities - Design of Participatory Spaces in Public Housing Using Network Configurational Theories
source	D. Holzer, W. Nakapan, A. Globa, I. Koh (eds.), RE: Anthropocene, Design in the Age of Humans - Proceedings of the 25th CAADRIA Conference - Volume 2, Chulalongkorn University, Bangkok, Thailand, 5-6 August 2020, pp. 283-292
doi	https://doi.org/10.52842/conf.caadria.2020.2.283
summary	This research-by-design project explores how public housing estates can accommodate social diversity and the appropriation of shared spaces, using qualitative and quantitative analysis of circulation networks. A case study housing estate in Hong Kong was analysed through field observations of movements and activities and as a site for the speculative re-design of shared spaces. Generative design processes were developed based on several parameters, including shortest paths, visibility integration and connectivity integration (Hillier & Hanson, 1984). Additional tools were developed to combine these techniques with optimisation of sunlight access, maximisation of views for residential towers and the provision of permeability of ground level building volumes. The project demonstrates how flexibility of use and social engagement can constitute a platform for self-organisation, similar to Jane Jacobs' notion of vibrant streets leading to active and progressive communities. It shows how computational design and configurational theories can promote a bottom-up approach for generating new types of residential environments that support participatory and diverse communities, rather than a conventional top-down approach that is perceived to embody mechanisms of social regimentation.

title	The Integration of Economic Analysis and Computer-based Building Models
source	CIB W-65 Symposium. July, 1984. [19] p. : ill. includes bibliography
summary	Most current methods used to evaluate the economics of building designs are inadequate in that they focus on the evaluation of completed designs and do not assist in the development and creation of designs. They are used after most major design decisions have been made. This paper describes the first year of a two year research project (funded by the National Science Foundation, the U.S. Government) which seeks to integrate economic analysis techniques into design decision-making within the context of an interactive computer-aided architectural and engineering design system. Issues reviewed include the current state of computer software, existing economic analysis models and existing economic analysis software. A conclusion is reached that most economic analysis systems fall into the category of single purpose software and are not adaptable to the wide range of idiosyncratic evaluation models used in real estate, architecture, engineering, construction and building management. Objectives are proposed for a general purpose, interactive cost modeling system that is integrated with a geometric computer-based building model. Initial experiments with a prototype of this system at various stages of the design-construction-use process are discussed. Further development of this system as a research tool for exploring alternative economic modeling procedures is presented

title	Computer-Aided Energy Economics for Early Concept Design Analysis
source	Building Economics, International Symposium Proceedings (3rd : Canada). 1984? vol. 3: pp.46-57 : ill. includes bibliography
summary	Decisions that have the greatest impact on energy cost performance are made very early in the design process. The problem is that these early design decisions are rarely tested thoroughly until very late in design. Usually this is due to the difficulties inherent in the use of the more sophisticated analysis procedures. Hourly energy computer simulations are costly to use, often require detailed input preparation, and use large ''main-frame' computers. Easier to use energy evaluation tools such as manual calculations and simplified computer programs do not yield reliable results. This is particularly true when passive solar design solutions are being tested. However, even the sophisticated approaches often have a limited ability to comprehensively model the economic implications of the more accurate energy simulations. This paper is intended to describe efforts at the University of Michigan to develop a more integrated approach to the assessment of energy economics - one that may be used at the earliest stages of concept design. The approach taken has been to concentrate on developing interactive, easy to use computer programs to describe building design proposals. This computer-generated building model is then used to automatically generate the information required to run a large, sophisticated energy analysis program developed by the U.S. Army Corps of Engineers (BLAST). Total life cycle cost analysis is performed either using procedures within BLAST or an 'electronic spreadsheet' system. Perceived deficiencies in the current state of this energy/cost evaluation system are described, and future research directions are presented

title	Perspective Vienna – A Comparison of Planning Scenarios and Real Development
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	With the suspension of national boarders in unions of nations, cities and their regions gain in significance for the economic, social and cultural development. This is particularly valid for Vienna, which lies close to the eastern boarder of the European Union, which should fall with the enlargement of EU in the near future. Of prominent importance is therefore to obtain a comprehensive understanding between proposed and defined aims for an urban development, the related measures and their extent ofimplementations and their actual or real effects. This paper attempts to give a strategic analysis of the Viennese urban and traffic development programs, from 1962, 1972, 1984 and 1994, on the one hand, and the data analysis of the statistical year books beginning from 1960 until 2000, on the other. The results show that adjustments have been made not only in response to certain trends, but also to a change of philosophy of urban development. It can be seen that certain assumptions of, for example, economic and transport measures can have the opposite outcome in relation to the intended objectives. Hence, one main question remains to beanswered: How should Vienna deal with the challenges ahead, to secure and foster a sustainable development under such circumstances on a long-term basis. In this respect, some measures are given, which should make it possible to overcome successfully these challenges.

title	Is Design Really Social
source	International Journal of Virtual Reality, 4:1
summary	There are many who will readily agree with Mitchell's assertion that "the most interesting new directions (for computer-aided design) are suggested by the growing convergence of computation and telecommunication. This allows us to treat designing not just as a technical process... but also as a social process." [Mitchell 1995]. The assumption is that design was a social process until users of computer-aided design systems were distracted into treating it as a merely technical process. Most readers will assume that this convergence must and will lead to increased communication between design participants, that better social interaction leads to be better design. The unspoken assumption appears to be that putting the participants into an environment with maximal communication channels will result in design collaboration. The tools provided, therefore, must permit the best communication and the best social interaction. We see a danger here, a pattern being repeated which may lead us into less than useful activities. As with several (popular) architectural design or modelling systems already available, however, computer system implementations all too often are poor imitations manual systems. For example, few in the field will argue with the statement that the storage of data in layers in a computer-aided drafting system is an dispensable approach. Layers derive from manual overlay drafting technology [Stitt 1984] which was regarded as an advanced (manual) production concept at the time many software engineers were specifying CAD software designs. Early implementations of CAD systems (such as RUCAPS, GDS, Computervision) avoided such data organisation, the software engineers recognising that object-based structures are more flexible, permitting greater control of data editing and display. Layer-based systems, however, are easier to implement in software, more familiar to the user and hence easier to explain, initially easier to use but more limiting for an experienced and thoughtful user, leading in the end to a lesser quality in resultant drawings and significant problems in output control (see Richens [1990], pp. 31-40 for a detailed analysis of such features and constraints). Here then we see the design for architectural software faithfully but inappropriately following manual methods. So too is there a danger of assuming that the best social interaction is that done face-to-face, therefore all collaborative design communications environments must mimic face-to-face.

summary	Graduate Institute of Architecture, National Chiao Tung University, Hsinchu, 30050, TAIWAN The adaptation of the word cyberspace (Gibson, 1984) following the emergence of the World Wide Web Internet not only succinctly revolutionized the correlation of time and space but also poised to challenge how we view the existing spatial concept. This research tries to use protocol analysis to examine text-based cyberspace, such as bulletin board, chart rooms and so forth, and the objective of this research is to realize the spatiality of cyberspace through the cognitive point of view, and to compare the differences of the definitions and perception ways of spatiality between people with general domain and in design fields. Finally, we validate the existence of cyberspace, where the process not only allows further categorization of spatial elements concluded from the earlier study, but discover that varied backgrounds can affect how a user defines and perceives cyberspace (Strate, 1999).

title	Automatic Finite- Element Mesh Generation from Geometric Models : A Point Based Approach
source	ACM Transactions on Graphics. October, 1984. vol. 3: pp. 287-311 : ill. includes bibliography
summary	A novel algorithm for automatic finite-element mesh generation is described. It uses constructive solid geometry to provide the geometric data for the object to be meshed. The geometric definition of the object and a value for the required mesh density are the only inputs. The method consists of two stages: point generation and mesh construction over the points. It has been implemented in two dimensions and is capable of generating predominantly 'good' quadrilateral elements. Triangular elements are only created in circumstances under which quadrilateral elements are not feasible

title	A New Concept and Method for Line Clipping
source	ACM Transactions on Graphics. January, 1984. vol. 3: pp. 1-22 : ill. includes bibliography
summary	A new concept and method for line clipping is developed that describes clipping in an exact and mathematical form. The basic ideas form the foundation for a family of algorithms for two-dimensional, three-dimensional, and four-dimensional (homogeneous coordinates) line clipping. The line segment to be clipped is mapped into a parametric representation. From this, a set of conditions is derived that describes the interior of the clipping region. Observing that these conditions are all of similar form, they are rewritten such that the solution to the clipping problem is reduced to a simple max/min expression. For each dimension, the mathematics are discussed, an example is given, the algorithm is designed, and a performance test is conducted. The new algorithm is compared with the traditional Sutherland-Cohen clipping algorithm. Using randomly generated data, the new algorithm showed a 36 percent, 40 percent, and 79 percent improvement for two-dimensional, three-dimensional, and four- dimensional clipping, respectively. One of the advantages of this algorithm is the quick rejection of line segments that are invisible. In addition, this algorithm can be easily generalized for clipping against any convex viewing volume

summary	In Belgium there are two possibilities to study architecture, it can either be done at a higher institute or academy, or at a university. At the higher schools of architecture the computer equipment has just been installed during the last years, and teaching of CAAD is not yet integrated. There exists only a general computer course. At the universities hardware has been available since several years, and software has been developed. The following programs have been implemented in Liege : LPB1, LPB2, LPB3, LPB4 (energy analysis), FEASIBILITY (to obtain acceptable values for the main global parameters of a design), VOLUME, (3D modelling for building modelisation and manipulation) and TYPOLOGIE (for the determination of classes for the energetic behaviour of residential buildings).

source	ASHRAE Transactions. 1984. vol. 90: [14] p. : ill. and tables. includes bibliography: p. [7]
summary	A method for the design of fixed and movable external sunshaeds for windows is presented. The window can have any shape and be located on a wall having an arbitrary orientation. The fundamental idea is to use a computer to generate the entire envelope of the family of shading solutions that satisfies a prescribed set of shading requirements. The envelope of solutions serves as a nomogram on the basis of which sunshades are designed. Any sunshade designed following this nomogram satisfies the prescribed demands. The method creates an unlimited space of solutions, leaving the final design to the architect's imagination

summary	This paper examines analytical procedures aimed at the study of the functional condition of architectural artefacts and, as a result, the promotion of a better understanding of the connections established with spatial conditions. The goal is to contribute to the development of techniques based on computer vision of mobility and users’ interaction, producing non-arbitrary registries of their movement/navigation and occupancy/co-presence patterns via a quantitatively based analysis.Movement/navigation and occupancy/co-presence patterns were correlated with configurational properties obtained by applying the space syntax descriptive model (Hillier and Hanson, 1984). It was possible to analyse relations between the spatial configuration and the movement/navigation and occupancy/co-presence patterns, a key question within the architectural conceptual process.

source	Computer-Aided Architectural Design Futures [CAAD Futures Conference Proceedings / ISBN 0-408-05300-3] Delft (The Netherlands), 18-19 September 1985, pp. 92-102
summary	Three-dimensional computer visualization has intrigued both building designers and computer scientists for decades. Research and conference papers present an extensive list of existing and potential uses for threedimensional geometric data for the building industry (Baer et al., 1979). Early studies on visualization include urban planning (Rogers, 1980), treeshading simulation (Schiler and Greenberg, 1980), sun studies (Anon, 1984), finite element analysis (Proulx, 1983), and facade texture rendering (Nizzolese, 1980). With the advent of better interfaces, faster computer processing speeds and better application packages, there had been interest on the part of both researchers and practitioners in three-dimensional -models for energy analysis (Pittman and Greenberg, 1980), modelling with transparencies (Hebert, 1982), super-realistic rendering (Greenberg, 1984), visual impact (Bridges, 1983), interference clash checking (Trickett, 1980), and complex object visualization (Haward, 1984). The Division of Building Research is currently investigating the application of geometric modelling in the building delivery process using sophisticated software (Evans, 1985). The first stage of the project (Vanier, 1985), a feasibility study, deals with the aesthetics of the mode. It identifies two significant requirements for geometric modelling systems: the need for a comprehensive data structure and the requirement for realistic accuracies and tolerances. This chapter presents the results of the second phase of this geometric modelling project, which is the construction of 'working' and 'presentation' models for a building.

title	Visual and Spatial Analysis in Office Design
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	The demands for rapid response to complex problems, flexibility, and other characteristics of today's workplace, such as a highly trained work force, have led many organizations to move from strict hierarchical structures to a more flexible project team organization. The organizational structure is broader and flatter, with greater independence given to organizational units, in this case the project teams. To understand the relationship between project team communication patterns and the design and layout of team space, a study was conducted of an architectural office before and after a move to new space. The study involved three project teams. Information was collected on individual communication patterns; perceptions of the ease of communication; and the effectiveness of the design and layout of physical space to support these communications. In order to provide guidance for critical decision-making in design, these communication data were correlated with a series of measures for the specification of team space enclosure and layout. These group/team space measures were adaptations of existing measures of individual work space, and included an enclosure measure, based on an enclosure measure developed by Stokols (1990); a measure of visual field, based on the "isovist" fields of Benedikt (1979); and an "integration" measure, based on the work of Hillier and Hanson (1984). Results indicate both linear and non-linear relationships between interaction patterns and physical space measures. This work is the initial stage of a research program to define a set of specific physical measures to guide the design of supportive work space for project teams and work groups within various types of organizations.

doi	https://doi.org/10.52842/conf.caadria.1996.131
summary	The rapid speed of computer development brings new technologies, and these advances require innovative investigations to apply them optimally in the field of architecture. Burkett (1984) demonstrated that computer graphics can ‘provide an excellent opportunity for exploring solar issues in building redesign’. With one of the latest computer technologies, the "hyper-model” environment, this research investigates how to environment can become an aid in the design and decision support area. The research first reviews the communication between the architect and the client as described by Salisbury (1990). The review indicates that an interactive 3D hypermedia paradigm, with quick response, fast data manipulation and 3D visualization, offers a better communication media between the architect and the client. This research applies the "hyper-model” environment to design and develop a new methodology in collecting, analyzing, and presenting solar data. It also endeavors to show the possibilities of using the environment in design process.

summary	Architectural design has been changing because of the vast and creative use of computer in different ways. From the viewpoint of designing itself, computer has been used as drawing tools in the latter phase of design (Mitchell 1977; Coyne et al. 1990), presentation and simulation tools in the middle phase (Liu and Bai 2000), and even critical media which triggers creative thinking in the very early phase (Maher et al. 2000; Liu 1999; Won 1999). All the various roles that computer can play have been adopted in a number of professional design corporations and so-called computer-aided design (CAD) studio in schools worldwide (Kvan 1997, 2000; Cheng 1998). The processes and outcomes of design have been continuously developing to capture the movement of the computer age. However, from the viewpoint of social-cultural theories of architecture, the evolvement of design cannot be achieved solely by designers or design processes. Any new idea of design can be accepted socially, culturally and historically only under one condition: The design outcomes could be reviewed and appreciated by critics in the field at the time of its production (Csikszentmihalyi 1986, 1988; Schon and Wiggins 1992; Liu 2000). In other words, aspects of design production (by designers in different design processes) are as critical as those of design appreciation (by critics in different review processes) in the observation of the future trends of architecture.Nevertheless, in the field of architectural design with computer and Internet, that is, so-called computer-aided design computer-mediated design, or internet-based design, most existing studies pay more attentions to producing design in design processes as mentioned above. Relatively few studies focus on how critics act and how they interact with designers in the review processes. Therefore, this study intends to investigate some evolving phenomena of the interaction between design production and appreciation in the environment of computer and Internet.This paper takes a CAD studio and an Internet-based competition as examples. The CAD studio includes 7 master's students and 2 critics, all from the same countries. The Internet-based competition, held in year 2000, includes 206 designers from 43 counties and 26 critics from 11 countries. 3 students and the 2 critics in the CAD studio are the competition participating designers and critics respectively. The methodological steps are as follows: 1. A qualitative analysis: observation and interview of the 3 participants and 2 reviewers who join both the CAD studio and the competition. The 4 analytical criteria are the kinds of presenting media, the kinds of supportive media (such as verbal and gesture/facial data), stages of the review processes, and interaction between the designer and critics. The behavioral data are acquired by recording the design presentation and dialogue within 3 months. 2. A quantitative analysis: statistical analysis of the detailed reviewing data in the CAD studio and the competition. The four 4 analytical factors are the reviewing time, the number of reviewing of the same project, the comparison between different projects, and grades/comments. 3. Both the qualitative and quantitative data are cross analyzed and discussed, based on the theories of design thinking, design production/appreciation, and the appreciative system (Goodman 1978, 1984).The result of this study indicates that the interaction between design production and appreciation during the review processes could differ significantly. The review processes could be either linear or cyclic due to the influences from the kinds of media, the environmental discrepancies between studio and Internet, as well as cognitive thinking/memory capacity. The design production and appreciation seem to be more linear in CAD studio whereas more cyclic in the Internet environment. This distinction coincides with the complementary observations of designing as a linear process (Jones 1970; Simon 1981) or a cyclic movement (Schon and Wiggins 1992). Some phenomena during the two processes are also illustrated in detail in this paper.This study is merely a starting point of the research in design production and appreciation in the computer and network age. The future direction of investigation is to establish a theoretical model for the interaction between design production and appreciation based on current findings. The model is expected to conduct using revised protocol analysis and interviews. The other future research is to explore how design computing creativity emerge from the process of producing and appreciating.
