title	Daylight Simulation: Validation, Sky Models and Daylight Coefficients
source	De Montfort University, Leicester, UK
summary	The application of lighting simulation techniques for daylight illuminance modelling in architectural spaces is described in this thesis. The prediction tool used for all the work described here is the Radiance lighting simulation system. An overview of the features and capabilities of the Radiance system is presented. Daylight simulation using the Radiance system is described in some detail. The relation between physical quantities and the lighting simulation parameters is made clear in a series of progressively more complex examples. Effective use of the inter-reflection calculation is described. The illuminance calculation is validated under real sky conditions for a full-size office space. The simulation model used sky luminance patterns that were based directly on measurements. Internal illuminance predictions are compared with measurements for 754 skies that cover a wide range of naturally occurring conditions. The processing of the sky luminance measurements for the lighting simulation is described. The accuracy of the illuminance predictions is shown to be, in the main, comparable with the accuracy of the model input data. There were a number of predictions with low accuracy. Evidence is presented to show that these result from imprecision in the model specification - such as, uncertainty of the circumsolar luminance - rather than the prediction algorithms themselves. Procedures to visualise and reduce illuminance and lighting-related data are presented. The ability of sky models to reproduce measured sky luminance patterns for the purpose of predicting internal illuminance is investigated. Four sky models and two sky models blends are assessed. Predictions of internal illuminance using sky models/blends are compared against those using measured sky luminance patterns. The sky model blends and the Perez All-weather model are shown to perform comparably well. Illuminance predictions using measured skies however were invariably better than those using sky models/blends. Several formulations of the daylight coefficient approach for predicting time varying illuminances are presented. Radiance is used to predict the daylight coefficients from which internal illuminances are derived. The form and magnitude of the daylight coefficients are related to the scene geometry and the discretisation scheme. Internal illuminances are derived for four daylight coefficient formulations based on the measured luminance patterns for the 754 skies. For the best of the formulations, the accuracy of the daylight coefficient derived illuminances is shown to be comparable to that using the standard Radiance calculation method. The use of the daylight coefficient approach to both accurately and efficiently predict hourly internal daylight illuminance levels for an entire year is described. Daylight coefficients are invariant to building orientation for a fixed building configuration. This property of daylight coefficients is exploited to yield hourly internal illuminances for a full year as a function of building orientation. Visual data analysis techniques are used to display and process the massive number of derived illuminances.

title	Measuring user satisfaction for design variations through virtual reality
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	This paper describes Virtual Reality as an environment to collect information about user satisfaction. Because Virtual Reality (VR) allows visualization with added interactivity, this form of representation has particular advantages when presenting new designs. The paper reports on the development of a VR system that supports architects to collect opinions about their design alternatives in terms of user preferences. An alternative to conjoint analysis, that uses statistical choice variations to estimate user preference functions, is developed. Artificial Intelligence (AI) Agent technology will be implemented to build a model for data collection, prediction, and learning processes.

title	High-precision application of GPS in the field of real-time equipment positioning
source	Automation in Construction 9 (3) (2000) pp. 299-314
summary	In the frame of its research concerning real-time positioning and control of road construction equipment, the Laboratoire Central des Ponts et Chaussées, has carried out in 1996 a study to know more about the actual vertical accuracy that a real-time kinematic (RTK) global positioning system (GPS) sensor could reach, under work site conditions. This study has widely used the dedicated testing facility called SESSYL, built to perform high-accuracy and real-time evaluation tests on positioning systems. It has been performed in collaboration with the French road contractor COLAS and the Ecole Supérieure des Géomètres et Topographes (ESGT). First, there is the proposed adapted geodetic transformation procedure, compatible with the high accuracy requirements. Then, the main results of a special SESSYL tests program are presented, where the impacts of several influencing parameters on the vertical accuracy have been carefully examined. The core part of the paper is the analysis of the typical RTK GPS set of data, from which we have tried to extract two different components: a high-frequency noise, rather easy to filter, and a low-frequency bias. This bias, given its good repeatability, can be modelled and used in prediction to improve in real-time the raw accuracy of the data. As a full-scale validation of our study, a site experiment is finally described, carried out this time on a real piece of equipment (an asphalt paver) during real roadwork.

title	Data Mining - Practical Machine Learning Tools and Techniques with JAVA Implementations
source	Morgan Kaufmann
summary	Witten and Frank's textbook was one of two books that I used for a data mining class in the Fall of 2001. The book covers all major methods of data mining that produce a knowledge representation as output. Knowledge representation is hereby understood as a representation that can be studied, understood, and interpreted by human beings, at least in principle. Thus, neural networks and genetic algorithms are excluded from the topics of this textbook. We need to say "can be understood in principle" because a large decision tree or a large rule set may be as hard to interpret as a neural network. The book first develops the basic machine learning and data mining methods. These include decision trees, classification and association rules, support vector machines, instance-based learning, Naive Bayes classifiers, clustering, and numeric prediction based on linear regression, regression trees, and model trees. It then goes deeper into evaluation and implementation issues. Next it moves on to deeper coverage of issues such as attribute selection, discretization, data cleansing, and combinations of multiple models (bagging, boosting, and stacking). The final chapter deals with advanced topics such as visual machine learning, text mining, and Web mining.

title	Digital Tectonic Design
doi	https://doi.org/10.52842/conf.ecaade.2000.287
source	Promise and Reality: State of the Art versus State of Practice in Computing for the Design and Planning Process [18th eCAADe Conference Proceedings / ISBN 0-9523687-6-5] Weimar (Germany) 22-24 June 2000, pp. 287-290
summary	Digital tectonic design is a fresh approach to architectural design methodology. Tectonics means a focus on assemblies of construction elements. Digital tectonics is an evolving methodology that integrates use of design software with traditional construction methods. We see digital tectonic design as a systematic use of geometric and spatial ordinances, used in combination with details and components directly related to contemporary construction. The current approach will, we hope, lead to an architectural curriculum based on generative form making where the computer can be used to produce systems of forms algorithmically. Digital design has tended to remain abstract, emphasizing visual and spatial arrangements often at the expense of materials and construction. Our pursuit is translation of these methods into more fully realized physical qualities. This method offers a rigorous approach based on close study of geometry and building construction elements. Giving a context for this approach, historical examples employing systematic tectonic design are explored in this paper. The underlying geometric ordinance systems and the highly tuned relationships between the details in these examples offer design vocabularies for use within the studio curriculum. The paper concludes with a detailed example from a recent studio project demonstrating particular qualities developed within the method. The method involves a wide range of scales, relating large-scale gestural and schematic studies to detailed assembly systems. Designing in this way means developing geometric strategies and, in parallel, producing detailed symbols or objects to be inserted. These details are assembled into a variety of arrays and groups. The approach is analogous to computer-aided designÕs tradition of shape grammars in which systems of spatial relationships are used to control the insertion of shapes within a space. Using this approach, a three-dimensional representation of a building is iteratively refined until the final result is an integrated, systematically organized complex of symbols representing physical building components. The resulting complex offers substantial material qualities. Strategies of symbol insertions and hierarchical grouping of elements are familiar in digital design practice. However these strategies are usually used for automated production of preconceived designs. In contrast to thsse normal approaches this presentation focuses on emergent qualities produced directly by means of the complex arrays of symbol insertions. The rhyth

title	Spatial reasoning: improving computational efficiency
source	Automation in Construction 9 (4) (2000) pp. 361-367
summary	When spatial data is analysed the result is often very computer intensive: even by the standards of contemporary technologies, the machine power needed is great and the processing times significant. This is particularly so in 3-D and 4-D scenarios. What we describe here is a technique, which tackles this and associated problems. The technique is founded in the idea of quad-tesseral addressing; a technique, which was originally applied to the analysis of atomic structures. It is based on ideas concerning Hierarchical clustering developed in the 1960s and 1970s to improve data access time [G.M. Morton, A computer oriented geodetic database and a new technique on file sequencing, IBM Canada, 1996.], and on atomic isohedral (same shape) tiling strategies developed in the 1970s and 1980s concerned with group theory [B. Grunbaum, G.C. Shephard, Tilings and Patterns, Freeman, New York, 1987.]. The technique was first suggested as a suitable representation for GIS in the early 1980s when the two strands were brought together and a tesseral arithmetic applied [F.C. Holdroyd, The Geometry of Tiling Hierarchies, Ars Combanitoria 16B (1983) 211–244.; S.B.M. Bell, B.M. Diaz, F.C. Holroyd, M.J.J. Jackson, Spatially referenced methods of processing raster and vector data, Image and Vision Computing 1 (4) (1983) 211–220.; Diaz, S.B.M. Bell, Spatial Data Processing Using Tesseral Methods, Natural Environment Research Council, Swindon, 1986.]. Here, we describe how that technique can equally be applied to the analysis of environmental interaction with built forms. The way in which the technique deals with the problems described is first to linearise the three-dimensional (3-D) space being investigated. Then, the reasoning applied to that space is applied within the same environment as the definition of the problem data. We show, with an illustrative example, how the technique can be applied. The problem then remains of how to visualise the results of the analysis so undertaken. We show how this has been accomplished so that the 3-D space and the results are represented in a way which facilitates rapid interpretation of the analysis, which has been carried out.

title	Capturing Histories of Design Processes for Collaborative Building Design Development. Field Trial of the ADS Prototype
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 427-437
summary	The ADS Project - Advanced Design Support for the Construction Design Process - builds on the technological results of the previous COMMIT Project to exploit and demonstrate the benefits of a CAD based Design Decision Support System. COMMIT provides a system for storing knowledge about knowledge within the design process. It records design decisions, the actors who take them and the roles they play when doing so. ADS links COMMIT to an existing object-oriented CAD system, MicroStation/J from Bentley Systems. The project focuses on tackling the problem of managing design information without intruding too much on the design process itself. It provides the possibility to effectively link design decisions back to requirements, to gather rationale information for later stages of the building lifecycle, and to gather knowledge of rationale for later projects. The system enables members of the project team, including clients and constructors, to browse and search the recorded project history of decision making both during and after design development. ADS aims to facilitate change towards a more collaborative process in construction design, to improve the effectiveness of decision-making throughout the construction project and to provide clients with the facility to relate design outcomes to design briefs across the whole building life cycle. In this paper we will describe the field trials of the ADS prototype carried out over a three-month period at the Building Design Partnership (BDP) Manchester office. The objective of these trials is to assess the extent, to which the approach underlying ADS enhances the design process, and to gather and document the views and experiences of practitioners. The ADS prototype was previously tested with historical data of real project (Peng, Cerulli et al. 2000). To gather more valuable knowledge about how a Decision Support System like ADS can be used in practice, the testing and evaluation will be extended to a real project, while it is still ongoing. The live case study will look at some phases of the design of a mixed residential and retail development in Leeds, UK, recording project information while it is created. The users’ feedback on the system usability will inform the continuous redevelopment process that will run in parallel to the live case study. The ADS and COMMIT Projects were both funded by EPSRC.

summary	Art historians and critics have defined the style as common features appeared in a class of objects. Abstract common features from a set of objects have been used as a bench mark for date and location of original works. Common features in shapes are identified by relationships as well as physical properties from shape descriptions. This paper will focus on how the computer recognises common shape properties from a class of shape objects to learn style. Shape representation using schema theory has been explored and possible inductive generalisation from shape descriptions has been investigated.

title	A Virtual Reality Tool to Implement City Building Codes on Capitol View Preservation
doi	https://doi.org/10.52842/conf.acadia.2000.203
source	Eternity, Infinity and Virtuality in Architecture [Proceedings of the 22nd Annual Conference of the Association for Computer-Aided Design in Architecture / 1-880250-09-8] Washington D.C. 19-22 October 2000, pp. 203-209
summary	In urban planning, the urban environment is a very complicated system with many layers of building codes cross-referenced and interacting together to guide urban growth. Especially, if a new urban design is located in a historical area, additional restrictions will be imposed upon regular zoning regulations to maintain the area’s historical characteristics. Often, urban regulations read as text are difficult to understand. A tool that generates adequate urban information and a quick visualization of the design will ease decision-making and enhance urban design processes. The goal of this research project is to develop a virtual reality (VR) tool with high resolution, speedy computation, and a userfriendly environment. This project initiates an interactive visualization tool to enforce city-planning regulations on viewing access to the state capitol building in Des Moines, Iowa. The capitol building houses the Iowa Legislature and is a symbol of state power. Maintaining the view from surrounding areas will preserve the building’s monumental and symbolic meaning. To accomplish this, the City Community Development Department and the Capitol Planning Committee developed a Capitol View Corridor Project, which sets up seven visual corridors to prevent the view toward the capitol from being blocked by any future designs. Because city regulations are not easy for the public and designers to interpret and comprehend, this project intends to develop a VR tool to create a transparent environment for visualizing the city ordinances.

title	Vision-based obstacle detection and avoidance for autonomous land vehicle navigation in outdoor roads
source	Automation in Construction 10 (1) (2000) pp. 1-25
summary	An effective approach to obstacle detection and avoidance for autonomous land vehicle (ALV) navigation in outdoor road environments using computer vision and image sequence techniques is proposed. To judge whether an object newly appearing in the image of the current cycle taken by the ALV is an obstacle, the object shape boundary is first extracted from the image. After the translation from the ALV location in the current cycle to that in the next cycle is estimated, the position of the object shape in the image of the next cycle is predicted, using coordinate transformation techniques based on the assumption that the height of the object is zero. The predicted object shape is then matched with the extracted shape of the object in the image of the next cycle to decide whether the object is an obstacle. We use a reasonable distance measure to compute the correlation measure between two shapes for shape matching. Finally, a safe navigation point is determined, and a turn angle is computed to guide the ALV toward the navigation point for obstacle avoidance. Successful navigation tests show that the proposed approach is effective for obstacle detection and avoidance in outdoor road environments.

title	[Title missing]
source	International Conference on Generative Art
summary	This paper is a summary of my last degree in architecture (discussed in December 1999) with Prof. Celestino Soddu and Prof. Enrica Colabella. In this work I had the possibility to reach complexity by a generative approach with the construction of a paradigm that organizes the different codes of project identity. My general objective was to design shape complexity in variable categories : 3d space surfaces, 2d drawings and 2d textures. I was to discover the identity of one of my favourite architects of the 20th century : Antoni Gaudì, by constructing codes relative to shape complexity. I defined my particular objective in the possibility to abduct from Gaudì's imaginary reference the generatives codes that operate in the logical processing I use to create a possible species project. The next step was to verify the exact working of the new generative codes by means of 3d scenaries, that are recognizable as "Antoni Gaudì specie's architecture". Whit project processing on the generative codes and not on a possible resulting shape design, I was able to organize by my general paradigm the attributes of the project's species : different shapes, different attributes (color, scale, proportion), to get to possible and different scenarys, all recognizable by the relative class codes. I chose three examples in Barcellona built during the period 1902 to 1914 : The Parco Guell, Casa Batllò and Casa Milà are the three reference sceneryes that I used to create the generative codes. In the second step I defined different codes that operate in sequence (it is defined in the paradigm) : The generatives codes are only subjective; they are one possible solution of my interpretation of Antoni Gaudì's identity. This codes operate in four differents ways : Geometrical codes for 2d shapes Geometrical codes for interface relations Spatial codes for 3d extrusion of 2d shapes Geometrical codes for 2d and 3d texturing of generated surfaces. By a stratified application of this codes I arrived at one idea for all the generative processes but many different, possible scenaryes, all recognizable in Gaudì's species. So, my final result has made possible sceneryes belonging to related species defined previously. At the end of my research I designed a project by combination : using Antoni Gaudì's generative codes on a new 3d scenary with a shape catalyst : the Frank Lloyd Wright Guggenheim Museum of New York. In this process I created a "hybrid scenary" : a new species of architectural look; a Guggenheim museum planned by Wright with a god pinch of Gaudì.

title	Retrieval Tools in Building Case Bases
doi	https://doi.org/10.52842/conf.ecaade.2000.113
source	Promise and Reality: State of the Art versus State of Practice in Computing for the Design and Planning Process [18th eCAADe Conference Proceedings / ISBN 0-9523687-6-5] Weimar (Germany) 22-24 June 2000, pp. 113-116
summary	Most of the existing aids to building design rely on data base of cases representing solutions to problems that are thought to happen again at least in a similar way. Crucial for the success of the aid is the retrieval engine. In tour its efficiency depends on the way the cases are encoded. Whichever is this way cases will be represented at different levels of abstraction. The highest level will probably consist in an accessibility and adjacency graph. Another level could be a wire plan of the building. An easily workable representation of a graph is a square matrix. For any given building typology it is possible to write a list of encoded space types. This allows forming matrices that can be compared and their diversity measured. Here we present an algorithm that makes this job. Such an algorithm can be one of the case retrieval tools in the data base. It is likely that the designer has already some idea of the shape he wants for the building he is designing. A comparison between some geometric characteristics of the wire representation of the retrieved case and the corresponding ones of the imagined solution of the design problem can constitute a second test. The matching can be done

source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 56-60
summary	The study describes some of the aspects tackled within a current Ph.D. research where architectural applications of constructive, structural and organization processes existing in biological systems are considered. The present information processing capacity of computers and the specific software development have allowed creating a bridge between two holistic nature disciplines: architecture and biology. The crossover between those disciplines entails a methodological paradigm change towards a new one based on the dynamical aspects of forms and compositions. Recent studies about artificial-natural intelligence (Hawkins, 2004) and developmental-evolutionary biology (Maturana, 2004) have added fundamental knowledge about the role of the analogy in the creative process and the relationship between forms and functions. The dimensions and restrictions of the Evo-Devo concepts are analyzed, developed and tested by software that combines parametric geometries, L-systems (Lindenmayer, 1990), shape-grammars (Stiny and Gips, 1971) and evolutionary algorithms (Holland, 1975) as a way of testing new architectural solutions within computable environments. It is pondered Lamarck´s (1744-1829) and Weismann (1834-1914) theoretical approaches to evolution where can be found significant opposing views. Lamarck´s theory assumes that an individual effort towards a specific evolutionary goal can cause change to descendents. On the other hand, Weismann defended that the germ cells are not affected by anything the body learns or any ability it acquires during its life, and cannot pass this information on to the next generation; this is called the Weismann barrier. Lamarck’s widely rejected theory has recently found a new place in artificial and natural intelligence researches as a valid explanation to some aspects of the human knowledge evolution phenomena, that is, the deliberate change of paradigms in the intentional research of solutions. As well as the analogy between genetics and architecture (Estévez and Shu, 2000) is useful in order to understand and program emergent complexity phenomena (Hopfield, 1982) for architectural solutions, also the consideration of architecture as a product of a human extended phenotype can help us to understand better its cultural dimension.

summary	This paper proposes a group of strategies for the use of computer tools in modeling and decisions making process, particularly in those typical design projects of habitual professional labor. This design process is illustrated though a model that include promoter-investor’s interests, financial restrictions on a little consulting office, and usual design focuses on local union. These experiences are exemplified though specific projects with public and residential use developed and built in Venezuela and Chile, distant geographically but near in a same know-how of computer assisted architectural design in Latin America.

source	Emerging Technologies and Design: The Intersection of Design and Technology. Proceedings of the 2000 ACSA Technology Conference, MIT Cambridge (Massachusetts) 4-7 July 2000, pp.117-122
summary	Recently a significant philosophical split has appeared within the discipline of architecture. The split exists because the architectural profession is adopting a new digital framework, from which it can challenge the traditional cultural and technical pursuits of the discipline. This paper is about this split within the profession and about using it to develop challenging contemporary architectural forms that work to fill the ‘gap.’ So where does the split come from? Our discipline and its associated discourses have over time been informed by the technologies used to construct it, design it, and mediate it, but also constrained by these things and our understandings of them. With this in mind, one can realize that it is the technologies of the time that in fact shape the philosophical positions and styles adopted by both individual designers and entire genres. This gap isn’t an easy thing to pin down. It takes on several forms all of which seem to stem from the same source, that being the influence of information constructs on space. If anything this paper aims to uncover the differences and similarities of these constructs, and use them to understand the digital genre that presently surrounds us.

summary	Computer aided architectural design has spread throughout architecture schools in the United States as if sown upon the wind. Yet, the proliferation alone may not be a good measure of the computer’s impact on the curriculum or signify the true emergence of a digital design culture. The aura of a relatively new technology may blind us from understanding its actual place in the continuum of design education. The promise of the technology is to completely revolutionize design; however, the reality of change is perhaps rooted in an underlying connection to core design methods. This paper considers a transitional phase within a School reviewing its entire curriculum. Lessons may be found in the Bauhaus educational program at the beginning of the 20 th century and its response to the changing shape of society and industry.

summary	Shape grammars are well known approaches in design space exploration. This paper reviews the current work on shape grammars in design and suggests that considerable gains can be attained by integrating parametric shape grammar based design approaches with distributed constraint-based problem solving. Parametric grammars are represent design topologies while distributed constrain satisfaction can be used to maintain consistency and produce the space of feasible design solutions. Designers' decision making can be coordinated such that constraints cannot be violated and designs that exhibit the highest utility (value) are selected.

summary	An ever-increasing number of offices as also residential buildings are being realised by designers and investors in accordance with the concept of an intelligent building. Houses of the new generation are being constructed. This is possible thanks to dynamic progress in the development of computer and microprocessor engineering techniques. Putting into reality the idea of the 'intelligent building' will become one of the most interesting assignments of Polish building industry in the rapidly approaching XXI century. The term 'intelligent building' first appeared in the eighties. The idea behind this conception is aspiring to create a friendly, work supporting, effective environment. The revolution in telecommunications and information technology along with change in the standards of office work, have caused computer networks and modem systems of automation and protection, to invade buildings. From the technical point of view, an intelligent building is an object in which all the subsystems co-operate with each other, forming a friendly environment for man. For users of an intelligent building, the most important issue is realisation of the following aims: object management which includes both control of human resources and automation systems in the building and also efficient management of the building space in such a way that the costs of its utilisation are minimised. The possibility of optional installation of modern systems and equipment should be facilitated by the architecture itself. Therefore, the specifics of all the building elements should be taken into account right at the designing stage. The following features characterise an intelligent building: integration of telecommunication systems in the building, central management and supervision system and utilisation of structural cabling as the carrier of signals controlling most of the systems in the building. Presently, there is no building in Poland that could be characterised by the three features mentioned.

title	Investigating the Cognitive Behavior of Generating Idea Sketches. Neural Network Simulation

summary	In idea sketches, there are a number of ambiguous shapes. Designers will associate and transform some shapes into others (Liu, 1993). Then, they evaluate these shapes in terms of functions and design requirements; furthermore, they would have generated other shapes that certified the design requirements (Huang, 1999). However, not only is the idea of design composed of one element, but also consisted of varied components. The purpose of this paper is to investigate how designers generate ideas of multi-component products, and to simulate this phenomenon by neural networks. At the same time, this paper attempts to study the design cognitive behavior of idea-generating stages, and explores the designers' cognitive phenomenon. Therefore, there are two stages in this paper: First, I conduct a cognitive experiment to realize how designers generate the multi-component product and acquire the sketches that designers generated. Second, I train the neural networks to simulate the behavior of idea generation and explore the cognitive phenomenon in design sketches. As a result, networks associate one shape that trained before, and then generate a complete idea. This phenomenon is similar to the cognitive behavior of designers who saw the ambiguous shape as one shape, which was retrieved from LTM. Moreover, the neural network is examined by a rectangle, which is totally different from the training patterns. The network will associate a confused shape. But the network will associate different shapes by adjusting some critical parameters. Designers can generate variable shapes from one shape, but the signal neural network can't simulate this kind of behavior. On the contrary, this paper proposes five sequential networks to generate variable shapes from the same shape and simulates how designers develop ideas.
