title The Architecture of ScarCity Game - The craft and the digital as an alternative design process

summary The Architecture of ScarCity Game is a board game used as a pedagogical tool that challenges architecture students by involving them in a series of experimental design sessions to understand the design process of scarcity and the actual relation between the craft and the digital. This means "pragmatic delivery processes and material constraints, where the exchange between the artisan of handmade, representing local skills and technology of the digitally conceived is explored" (Huang 2013). The game focuses on understanding the different variables of the crafted design process of traditional communities under conditions of scarcity (Michel and Bevan 1992). This requires first analyzing the spatial environmental model of interaction, available human and natural resources, and the dynamic relationship of these variables in a digital era. In the first stage (Pre-Agency), the game set the concept of the craft by limiting students design exploration from a minimum possible perspective developing locally available resources and techniques. The key elements of the design process of traditional knowledge communities have to be identified (Preez 1984). In other words, this stage is driven by limited resources + chance + contingency. In the second stage (Post-Agency) students taking the architects´ role within this communities, have to speculate and explore the interface between the craft (local knowledge and low technological tools), and the digital represented by computation data, new technologies available and construction. This means the introduction of strategy + opportunity + chance as part of the design process. In this sense, the game has a life beyond its mechanics. This other life challenges the participants to exploit the possibilities of breaking the actual boundaries of design. The result is a tool to challenge conventional methods of teaching and leaning controlling a prescribed design process. It confronts the rules that professionals in this field take for granted. The game simulates a 'fake' reality by exploring in different ways with surveyed information. As a result, participants do not have anything 'real' to lose. Instead, they have all the freedom to innovate and be creative.

title A functional approach to realizing decision support systems in technical regulation management for design and construction
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 Technical building standards defining the quality of buildings, building products, building materials and building processes aim to provide acceptable levels of safety, health, usefulness and energy consumption. However, the logical consistency between these goals and the set of regulations produced to achieve them is often hard to identify. Not only the large quantities of highly complex and frequently changing building regulations to be met, but also the variety of user demands and the steadily increasing technical information on (new) materials, products and buildings have produced a very complex set of knowledge and data that should be taken into account when handling technical building regulations. Integrating knowledge technology and database technology is an important step towards managing the complexity of technical regulations. Generally, two strategies can be followed to integrate knowledge and database technology. The main emphasis of the first strategy is on transferring data structures and processing techniques from one field of research to another. The second approach is concerned exclusively with the semantic structure of what is contained in the data-based or knowledge-based system. The aim of this paper is to show that the second or knowledge-level approach, in particular the theory of functional classifications, is more fundamental and more fruitful. It permits a goal-directed rationalized strategy towards analysis, use and application of regulations. Therefore, it enables the reconstruction of (deep) models of regulations, objects and of users accounting for the flexibility and dynamics that are responsible for the complexity of technical regulations. Finally, at the systems level, the theory supports an effective development of a new class of rational Decision Support Systems (DSS), which should reduce the complexity of technical regulations and restore the logical consistency between the goals of technical regulations and the technical regulations themselves.

title Designing for Pedestrians : A CAD-Network Analysis Approach
source New York: John Wiley & Sons, 1992. pp. 379-398 : ill. includes a short bibliography
summary Microcomputer techniques have been developed that combine CAD drawings with transportation network analysis software that uses spreadsheets and stand-alone programs activated from the DOS operating system. The CAD feature simplifies and improves the methods used to design pedestrian circulation facilities and evaluate the impact of new development on existing pedestrian flows. Through the use of customized software, the need for manual data entry is reduced, and the graphical display of analysis results in most intermediate steps in the process are automated. Three hypothetical case studies are presented, concentrating on proposed pedestrian circulation improvements at Penn Station, New York

summary As well as learning traditional design techniques, students in architecture courses learn how to use powerful workstations with CAD systems, color scanners and laser printers and software for the rendering, compositing and animating of their designs.

They learn to use raytracing and radiosity rendering systems to provide visual realism, alpha-channel compositing systems to put a client in the picture (literally) or the design in situ, and keyframe animation systems to allow realistic walkthroughs.

Student Presentations are now based on videos, photographic slides, slide shows or real time animation. Images (as data files) are imported into full color publishing systems for final year thesis presentation.

The architectural graphics environment at Curtin University facilitates the integration of slide and video examples of raytraced and chroma-keyed images with computer aided design techniques for architectural student presentations.

summary The goal of this paper is to study problems of the transition from traditional architectural studio teaching to CAAD studio teaching which requires a CAAD expert system as studio tutor, and to study the behavior of the student in this new environment. The differences between the traditional and computerized studio teaching and the experiences in this field are explained referring to the requirements for designing time in relation to the expertise of the student in the application of a CAD program. Learning styles and the process of design in computerized and non-computerized studio teaching are discussed. Design studio requirements of the students in traditional studio environment while doing design works are clarified depending on the results of an empirical study which explained the relations between the tutor and the student while they were doing studio critiques. Main complaints of the students raised in the empirical study were the lack of data in the specific design problem area, difficulties of realization of ideas and thoughts, not knowing the starting point of design, having no information about the references to be used for the specific design task, having difficulties in the application of presentation techniques. In the concluding parts of the paper are discussed the different styles of teaching and their relation to the CAAD environment, the transformation of the instructional programs for the new design environment, the future expectations from the CAAD programs, properties of the new teaching environment and the roles of the expert systems in design studio education.

title A Data Model Analysis of Modularity and Extensibility in Building Databases
source Building and Environment, Vol 27, No: 2, pp. 135-148
summary This paper uses data modeling techniques to define how database schemas for an intelligent integrated architectural CAD system can be made extensible. It reviews the product data modeling language EDM, then applies it to define a part of an architectural data model. Extensions are then investigated, regarding how users could integrate various design-specific packages into a uniquely configured system. Both, extension by substituting one technology for another and by adding a new evaluation application, are considered. Data modeling allows specification of a CAD database and identification of the kind of modularization that will work and what problems may arise.''

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 Creating the Electronic Design Studio: Development of a Heterogeneous Networked Environment at Harvard's Graduate School of Design
source CAAD Instruction: The New Teaching of an Architect? [eCAADe Conference Proceedings] Barcelona (Spain) 12-14 November 1992, pp. 225-240

summary The migration of design education to reliance on computer-based techniques requires new ways of thinking about environments which can effectively support a diverse set of activities. Both from a spatial standpoint and a computing resource standpoint, design studios must be inevitably reconfigured to support new tools and reflect new ways of communicating. At Harvard's GSD, a commitment to incorporating computer literacy as a fundamental component of design education enables us to confront these issues through the implementation of a heterogeneous network imbedded in an electronic design environment. This evolving prototype of a new design studio, its development and its potential, will be the subject of this paper. A new style design environment is built upon an understanding of traditional techniques, and layered with an awareness of new tools and methods. Initially we borrow from existing metaphors which govern our interpretation of the way designers work. Next we seek to extend our thinking to include allied or related metaphors such as the library metaphor which informs collections of software and data, or the laboratory metaphor which informs workspace groupings, or the transportation metaphor which informs computer-based communications such as electronic mail or bulletin boards, or the utility services metaphor which informs the provision of network services and equipment. Our evaluation of this environment is based on direct feedback from its users, both faculty and students, and on subjective observation of the qualitative changes in communication which occur between and among these groups and individuals. Ultimately, the network must be judged as a framework for learning and evaluation, and its success depends both on its ability to absorb our existing metaphors for the process of design, and to prefigure the emerging metaphors to be envisioned in the future.

title Monitoring the Dynamics of Informal Settlements in Dar Es Salaam by Remote Sensing: Exploring the Use of Spot, Ers and Small Format Aerial Photography
source CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary Dar es Salaam is exemplary for cities in the developing world facing an enormous population growth. In the last decades, unplanned settlements have tremendously expanded, causing that around 70 percent of the urban dwellers are living now-a-days in these areas. Tools for monitoring such tremendous growth are relatively weak in developing countries, thus an effective satellite based monitoring system can provide a useful instrument for monitoring the dynamics of urban development. An investigation to asses the ability of extracting reliable information on the expansion and consolidation levels (density) of urban development of the city of Dar es Salaam from SPOT-HRV and ERS-SAR images is described. The use of SPOT and ERS should provide data that is complementary to data derived from the most recent aerial photography and from digital topographic maps. In a series of experiments various classification and fusion techniques are applied to the SPOT-HRV and ERS-SAR data to extract information on building density that is comparable to that obtained from the 1992 data. Ultimately, building density is estimated by linear and non-linear regression models on the basis of an one ha kernel and further aggregation is made to the level of informal settlements for a final analysis. In order to assess the reliability, use is made of several sample areas that are relatively stable over the study period, as well as, of data derived from small format aerial photography. The experiments show a high correlation between the density data derived from the satellite images and the test areas.

title Toward a procedure of computer simulation in the restoration of historical architecture

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 Housing tenancy, data management and quality control
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 This paper deals with housing tenancy, data management and quality control. The proposed method is focused on quality characteristics of housing estates in view of rentability risks. It entails a cycle of registration, analysis and implementation of measures. The starting point is the behaviour of the housing consumer in a market-oriented context. The model is framed within theories of strategic management and marketing. Systematic registration and evaluation of consumer behaviour, by means of a set of relevant process and product indicators, can yield relevant information in the four phases of the rental process: orientation, intake, dwelling and exit. This information concerns the way in which the dwelling (characterized by product indicators) fits the needs of the consumer. The systematic analysis of the process and product indicators during the phases of the rental process makes a 'strength-weakness analysis' of housing estates possible. The indicators can be presented in aggregated form by way of a 'rentability index. The 'strength-weakness analysis' steers the intervention in the quality characteristics of housing estates. The possibilities for readjustment, however, are different. The quality control system is not only an early warning system, but also has several other functions: evaluation, planning and communication. The method described here lays a solid foundation for a decision-support system in the area of housing tenancy.

title Using conceptual modelling and an object-oriented environment to support building cost control during early design
source College of Architecture and Urban Planning, University of Michigan
summary This research investigated formal information modelling techniques and the object-oriented knowledge representation on the domain of building cost control during early design stages. The findings contribute to an understanding of the advantages and disadvantages of applying formal modelling techniques to the analysis of architectural problems and the representation of domain knowledge in an object-oriented environment. In this study, information modelling techniques were reviewed, formal information analysis was performed, a conceptual model based on the cost control problem domain was created, a computational model based on the object-oriented approach was developed, a mechanism to support information broadcasting for representing interrelationships was implemented, and an object-oriented cost analysis system for early design (OBCIS) was demonstrated. The conceptual model, based on the elemental proposition analysis of NIAM, supports a formal approach for analyzing the problem domain; the analysis results are represented by high-level graphical notations, based on the AEC Building System Model, to visually display the information framework of the domain. The conceptual model provides an intermediate step between the system designer's view of the domain and the internal representation of the implementation platform. The object-oriented representation provides extensive data modelling abilities to help system designers intuitively represent the semantics of the problem domain. The object-oriented representation also supports more structured and integrated modules than conventional programming approaches. Although there are many advantages to applying this technique to represent the semantics of cost control knowledge, there are several issues which need to be considered: no single satisfactory classification method can be directly applied; object-oriented systems are difficult to learn; and designing reusable classes is difficult. The dependency graph and information broadcasting implemented in this research is an attempt to represent the interrelationships between domain objects. The mechanism allows users to explicitly define the interrelationships, based on semantic requirements, among domain objects. In the conventional approach, these relationships are directly interpreted by system designers and intertwined into the programming code. There are several issues which need to be studied further: indirect dependency relationship, conflict resolution, and request-update looping based on least-commitment approach.

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 This paper discusses some preliminary results of several knowledge-acquisition and documentation-structuring techniques that were used to assess the working styles of architects. The focus of this assessment was on their strategic design behaviour. Hettema's Interactive Personality Model (Hettema 1979, 1989) was used to explain and interpret these results. The methods used to acquire the necessary data are protocol analysis, card sorting and interviews. The results suggest that at least three parameters can be used to explain and differentiate the strategic design behaviour of architects. These parameters are S (site-oriented), B (brief-oriented) and C (concept-oriented). A priority hierarchy of these parameters reveals six major distinguishable working styles. These results are captured in a new design model that can be used in data bank implementations.

title Maximising the Benefits of CAD Systems in Architectural Education
source The Virtual Studio [Proceedings of the 12th European Conference on Education in Computer Aided Architectural Design / ISBN 0-9523687-0-6] Glasgow (Scotland) 7-10 September 1994, p. 228
doi https://doi.org/10.52842/conf.ecaade.1994.x.u8n
summary The positive impact of Computer Aided Design (CAD) in professional architectural practice has been in focus in recent times but relatively little has been written on its significance in the education of the contemporary architect. It is common knowledge that the profession of architecture is currently undergoing enormous strains as it battles to keep abreast of trends and developments in a period of series of rapid advancement in science, technology and management (RIBA, 1992). Whilst attempts are being made to redress the shortcomings of the profession in the above context, the requirements for architectural education are yet to forge a coherent strategy for the implementation of CAD/IT in the curriculum of schools of architecture. In almost every other field, including engineering, medicine and the humanities, computing application to problem-solving and decision-making is seen as a way forward as we move into 21st century. Architectural education must integrate CAD/IT into the teaching of core modules that give the architect distinctive competence: studio design. That is one of the best ways of doing justice to the education of the architect of today and the future. Some approaches to the teaching of CAD in schools of architecture have been touched upon in the recent past. Building upon this background as well as an understanding of the nature of design teaching/learning, this paper examines ways of maximising the benefits of CAD systems in architectural education and of bringing computer aided designing into the studio not only to enhance design thinking and creativity but also to support interactive processes. In order to maximise or optimise any function, one approach is to use the hard systems methodology which utilises analytic, analogic and iconic models to show the effect of those factors which are significant for the purposes being considered. The other approach is to use the soft systems methodology in which the analysis encompasses the concept of a human activity system as a means of improving a situation. The use of soft systems methodology is considered more appropriate for dealing with the problem of design which is characterised by a flux of interacting events and ideas that unroll through time. The paper concludes that the main impediment to maximising the benefits of CAD systems in architectural education is not only the inappropriate definition of the objectives for the implementation of CAD education but also that the control subsystems are usually ill-structured and relatively poorly defined. Schools must attempt to define a coherent and consistent policy on the use of CAD systems as an integral part of studio design and evolve an in-house strategic and operational controls that enable the set objectives to be met. Furthermore, it is necessary to support the high level of productivity from CAD systems with a more efficient management system, especially in dealing with communication, data sharing via relational database, co-ordination and integration. Finally, the use of soft systems methodology is recommended as the way forward to optimising CAD systems in design education as it would provide continuous improvements while maintaining their productive value.

title Digital Architecture in CAD studio and Internet-based competition

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.

title A Graphical Feedback Model for Computerized Energy Analysis during the Conceptual Design Stage
source Texas A&M University
summary During the last two decades, considerable effort has been placed on the development of building design analysis tools. Architects and designers have begun to take advantage of computers to generate and examine design alternatives. However, because it has been difficult to adapt computer technologies to the visual orientation of the building designer, the majority of computer applications have been limited to numerical analysis and office automation tasks. Only recently, because of advances in hardware and software techniques, computers have entered into a new phase in the development of architectural design. haveters are now able to interactively display graphics solutions to architectural related problems, which is fundamental to the design process. The majority of research programs in energy efficient design have sharpened people's understanding of energy principles and their application of those principles. Energy conservation concepts, however, have not been widely used. A major problem in the implementation of these principles is that energy principles their applications are abstract, hard to visualize and separated from the architectural design process. Furthermore, one aspect of energy analysis may contain thousands of pieces of numerical information which often leads to confusion on the part of designers. If these difficulties can be overcome, it would bring a great benefit to the advancement of energy conservation concepts. This research explores the concept of an integrated computer graphics program to support energy efficient design. It focuses on (1) the integration of energy efficiently and architectural design, and (2) the visualization of building energy use through graphical interfaces during the conceptual design stage. It involves (1) the discussion of frameworks of computer-aided architectural design and computer-aided energy efficient building design, and (2) the development of an integrated computer prototype program with a graphical interface that helps the designer create building layouts, analyze building energy interactively and receive visual feedbacks dynamically. The goal is to apply computer graphics as an aid to visualize the effects of energy related decisions and therefore permit the designer to visualize and understand energy conservation concepts in the conceptual phase of architectural design.

title Visualizing Negative Space
source Mission - Method - Madness [ACADIA Conference Proceedings / ISBN 1-880250-01-2] 1992, pp. 135-139

summary Designers and artists are, by training, accustomed to reversing figure /ground relationships-' They can easily picture and sketch negative (empty) spaces in plan or profile. Such perceptual reversals help them understand the voids between buildings as the dynamic and character-forming entities they are. Traditional drawing techniques like pocheing or hatching, just emphasize the static 2 dimensional aspects of these curious spaces: many sequential or layered views are needed to define their full 3 dimensional volume. Such multiple views are costly to produce and because of the 2 dimensional medium are inherently static and flat.

This research applies and further develops an under used visualization technique that depicts negative spaces (voids) as true 3 dimensional solids. It focuses specifically on visualizing outdoor spaces defined primarily by vegetation. The preliminary results are volumetrically revealing depictions of complex spaces. They give the designer and client quick spatial feedback about the intended "'open" space in a given design.

title Visualising Sydney's Urban Green: A Web Interface for Monitoring Vegetation Coverage between 1992 and 2022 using Google Earth Engine
source Nicole Gardner, Christiane M. Herr, Likai Wang, Hirano Toshiki, Sumbul Ahmad Khan (eds.), ACCELERATED DESIGN - Proceedings of the 29th CAADRIA Conference, Singapore, 20-26 April 2024, Volume 2, pp. 515–524

summary With continued population growth and urban expansion, the severity of environmental concerns within cities is likely to increase without proper urban ecosystem monitoring and management. Despite this, limited efforts have been made to effectively communicate the ecological value of urban vegetation to Architecture, Engineering and Construction (AEC) professionals concerned with mitigating these effects and improving urban liveability. In response, this research project proposes a novel framework for identifying and conveying historical changes to vegetation coverage within the Greater Sydney area between 1992 and 2022. The cloud-based geo-spatial analysis platform, Google Earth Engine (GEE), was used to construct an accurate land cover classification of Landsat imagery, allowing the magnitude, spatial configuration, and period of vegetation loss to be promptly identified. The outcomes of this analysis are represented through an intuitive web platform that facilitates a thorough understanding of the complex relationships between anthropogenic activities and vegetation coverage. A key finding indicated that recent developments in the Blacktown area had directly contributed to heightened land surface temperature, suggesting a reformed approach to urban planning is required to address climatic concerns appropriately. The developed web interface provides a unique method for AEC professionals to assess the effectiveness of past planning strategies, encouraging a multi-disciplinary approach to urban ecosystem management.

title The Intelligent Sketch: Developing a Conceptual Model for a Digital Design Assistant

summary The computer is a relatively new tool in the practice of Architecture. Since its introduction, there has been a desire amongst designers to use this new tool quite early in the design process. However, contrary to this desire, most Architects today use pen and paper in the very early stages of design to sketch. Architects solve problems by thinking visually. One of the most important tools that the Architect has at his disposal in the design process is the hand sketch. This iterative way of testing ideas and informing the design process with images fundamentally directs and aids the architect’s decision making. It has been said (Schön and Wiggins 1992) that sketching is about the reflective conversation designers have with images and ideas conveyed by the act of drawing. It is highly dependent on feedback. This “conversation” is an area worthy of investigation. Understanding this “conversation” is significant to understanding how we might apply the computer to enhance the designer’s ability to capture, manipulate and reflect on ideas during conceptual design. This paper discusses sketching and its relation to design thinking. It explores the conversations that designers engage in with the media they use. This is done through the explanation of a protocol analysis method. Protocol analysis used in the field of psychology, has been used extensively by Eastman et al (starting in the early 70s) as a method to elicit information about design thinking. In the pilot experiment described in this paper, two persons are used. One plays the role of the “hand” while the other is the “mind”- the two elements that are involved in the design “conversation”. This variation on classical protocol analysis sets out to discover how “intelligent” the hand should be to enhance design by reflection. The paper describes the procedures entailed in the pilot experiment and the resulting data. The paper then concludes by discussing future intentions for research and the far reaching possibilities for use of the computer in architectural studio teaching (as teaching aids) as well as a digital design assistant in conceptual design.
