title	Architectural Computing from Turing to 2000 [Conference Proceedings]

summary	The core theme of this book is the idea of looking forward to where research and development in Computer Aided Architectural Design might be heading. The contention is that we can do so most effectively by using the developments that have taken place over the past three or four decades in Computing and Architectural Computing as our reference point; the past informing the future. The genesis of this theme is the fact that a new millennium is about to arrive. If we are ruthlessly objective the year 2000 holds no more significance than any other year; perhaps we should, instead, be preparing for the year 2048 (2k). In fact, whatever the justification, it is now timely to review where we stand in terms of the development of Architectural Computing. This book aims to do that. It is salutary to look back at what writers and researchers have said in the past about where they thought that the developments in computing were taking us. One of the common themes picked up in the sections of this book is the developments that have been spawned by the global linkup that the worldwide web offers us. In the past decade the scale and application of this new medium of communication has grown at a remarkable rate. There are few technological developments that have become so ubiquitous, so quickly. As a consequence there are particular sections in this book on Communication and the Virtual Design Studio which reflect the prominence of this new area, but examples of its application are scattered throughout the book. In 'Computer-Aided Architectural Design' (1977), Bill Mitchell did suggest that computer network accessibility from expensive centralised locations to affordable common, decentralised computing facilities would become more commonplace. But most pundits have been taken by surprise by just how powerful the explosive cocktail of networks, email and hypertext has proven to be. Each of the ingredients is interesting in its own right but together they have presented us with genuinely new ways of working. Perhaps, with foresight we can see what the next new explosive cocktail might be.

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	DIAL-Europe: New Functionality’s for an Integrated Daylighting Design Tool
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	The European project DIAL-Europe started in April 2000 and intends to enhance and to enlarge the capabilities of the LesoDIAL software. The aim of this “Swiss” tool was to give architects relevant information regarding the use of daylight, at the very first stage of the design process. DIAL-Europe focuses on European standards and climatic data. Further, a Heating & Cooling evaluation module and an Artificial Lighting module will be added. The objective of the Heating & Cooling module is to indicate the implications of the user’s design on heating and cooling energy and on thermal comfort.The objective of Artificial Lighting module is to develop a tool that will give an estimation of illuminance values on the work plane and provide guidance on qualitative aspects and visual comfort as well as on switching control and integration with daylight based on generic light sources and luminaires. Furthermore, the scope of the examples of simulated rooms will be increased in order to allow the user to compare their design with more similar cases. This paper will present the state of achievement and give an overview of the first version of the DIAL-Europe software, which will beavailable at the beginning of 2002.

title	Possibilities and limitations of CFD simulation for indoor climate analysis
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	With the democratization of information and communication technologies, simulation techniques that used to be computationally expensive and time-consuming are becoming feasible instruments for the analysis of architectural design. Simulation is an indispensable ingredient of the descriptive design approach, which provides the designer with precise and accurate projections of the performance and behavior of a design. The paper describes the application of a particular class of simulation techniques, computational fluid dynamics (CFD), to the analysis and evaluation of indoor climate. Using two different CFD systems as representatives of the class, we describe: relevant computational possibilities and limitations of CFD simulation; the accessibility of CFD simulation for architects, especially concerning the handling of simulation variables; the compatibility of CFD representations of built space with similar representations in standard CAD and modeling systems, including possibilities for feedback; The relations between geometric representation and accuracy / precision in CFD simulation. We propose that CFD simulation can become an operational instrument for the designer, provided that CFD simulation does not become a trial and error game trying to master computational techniques. A promising solution to this problem is the use of case based reasoning. A case base of analyzed, evaluated and verified buildings provides a flexible source of information (guidance and examples) for both the CFD simulation and the designer.

title	Computer-aided design systems for the 21st century: some design guidelines
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 proposes nine design principles for a new generation of computer-aided design (CAD) systems that actively support the decision making and problem solving activities of environmental design. Foremost among these are: a meaningful internal object-based representation of the artifact being designed within its environmental context; a collaborative problem solving paradigm in which the human designer and the computer form a complementary partnership; and, the notion of decision-support tools rather than predefined solutions. Two prototype computer-aided design systems implemented by the CAD Research Center that embody most of these concepts are described. ICADS (Intelligent Computer-Aided Design System) incorporates multiple expert agents in domains such as natural and artificial lighting, noise control, structural system selection, climatic determinants, and energy conservation. Given a particular building design context, the agents in ICADS draw upon their own expertise and several knowledgebases as they monitor the actions of the human designer and collaborate opportunistically. KOALA (Knowledge-Based Object-Agent Collaboration) builds on the multi-agent concepts embodied in ICADS by the addition of two kinds of agents. Mentor agents represent the interests of selected objects within the ontology of the design environment. In the implemented KOALA system building spaces are represented by agents capable of collaborating with each other, with domain agents for the provision of expert services, and with the human designer. Facilitator agents listen in on the communications among mentor agents to detect conflicts and moderate arguments. While both of these prototype systems are limited in scope by focussing on the earliest design stages and restricted in their understanding of the inherent complexity of a design state, they nevertheless promise a paradigm shift in computer-aided design.

title	Construction simulation using parallel computing environments
source	Automation in Construction 10 (1) (2000) pp. 69-78
summary	The paper describes and compares alternative approaches to implementing construction simulation models within a multiprocessor computing environment. Both parallel-algorithmic and neural network based methods of simulating construction processes are considered, and compared with the conventional serial-algorithmic approach. The lines along which a simulation algorithm can be divided into tasks for parallel execution on a multiprocessor are first discussed, and the merits of each approach are identified. This is followed by a brief discourse on neural networks, their application to construction simulation, and the way in which such an implementation can be implemented within a multiprocessing environment. The merits and demerits of all approaches are discussed with particular reference to a model of an excavation system. A case study comparing the speed at which each implementation can process a simulation shows the neural approach to operate approximately two orders of magnitude faster than the alternatives. The paper concludes with an indication of future research to be conducted in this field.

title	Study of digital morphing tools during the design process - Application of freeware software and of tools in commercial products as well as their integration in AutoCAD
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	This research work examines methods of experimental designing with CAAD in a CAD laboratory with architecture students as the testing persons. Thereby the main focus is on the early phase of finding forms, in which different techniques with digital media are tried out in the didactic architectural design lessons. In these work have been traced the influences of the media employed on the design processes and combined the approaches of current CAAD research with aspects from classic design theory. For mathematical rules of proportion, atmospheric influence factors and analogy concepts in architecture, I have developed design methods which have been applied and verified in several series of seminars. (Kirschner, U.: 2000, Thesis, a CAAD supported architectural design teaching, Hamburg, school of arts). Previous experimental exercises showed that morphological sequences of modeling are effective sources for playful designing processes. In the current work these approaches are enhanced and supplemented by different morphological architectural concepts for creating shapes. For this purpose 2D based software like Morphit, Winmorph and other freeware were used. Whereas in the further development of this design technique we used 3D freeware morphing programs like zhu3D or Blender. The resulting morphological shapes were imported in CAD and refined. Ideally the morphing tool is integrated in the modeling environment of the standard software AutoCAD. A digital city model is the starting basis of the design process to guarantee the reference to the reality. The applied design didactic is predicated on the theories of Bernhard Hoesli. The act of designing viewed as „waiting for a good idea“ is, according to him, unteachable; students should, in contrast, learn to judge the „the force of an idea“. On the subject of morphology a form-generating method in the pre-design phase has been tested. Starting from urban-planning lines on an area map, two simple geometric initial images were produced which were merged by means of morphing software. Selected images from this film sequence were extruded with CAAD to produce solid models as sectional drawings. The high motivation of the students and the quality of the design results produced with these simple morphing techniques were the reason for the integration of the artistic and scientific software into the creative shape modeling process with the computer. The students learned in addition to the „bottom up “and „ top down” new design methods. In the presentation the properties and benefits of the morphing tools are presented in tables and are analyzed with regard to the architectural shape generating in an urban context. A catalogue of criteria with the following topics was developed: user friendliness, the ability of integrating the tools or as the case may be the import of data into a CAD environment, the artistic aspects in terms of the flexibility of shape generating as well as the evaluation of the aesthetic consideration of shapes.

title	Grammatical and syntactic properties of CAAD representations for the early design stages
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	CAAD representations for the early design stages have traditionally focused on aspects apparently relating to design creativity, such as flexible, effortless and rich geometric modelling. However, modelling capabilities are generally unconnected to the control and analysis of design constraints that affect the further development of the design. These usually refer to functional and spatial aspects that are only implicit in a CAAD representation of design ‘solids’. Moreover, the stability and reliability of control and analysis rely on the grammatical and syntactic quality of the representation. In particular, (a) the grammatical well-formedness of spatial and building primitives, and (b) the syntactic completeness and unambiguity of spatial relations are essential prerequisites to any meaningful analysis of aspects such as fulfilment of programmatic requirements, indoor climate, lighting or human interaction with the built environment. The paper describes a dual spatial and building element representation implemented on top of a standard drawing system. The representation attempts to minimize input requirements, while at the same time providing feedback on the grammatical and syntactic quality of the design description.

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	Desktop Radiance A New Tool for Computer-Aided Daylighting Design
doi	https://doi.org/10.52842/conf.acadia.2000.009
source	ACADIA Quarterly, vol. 19, no. 2, pp. 9-11
summary	The use of daylight for the illumination of building interiors has the potential to enhance the quality of the environment while providing opportunities to save energy by replacing or supplementing electric lighting. Moreover, it has the potential to reduce heating and cooling loads, which offer additional energy saving opportunities, as well as reductions in HVAC equipment sizing and cost. All of these benefits, however, assume proper use of daylighting strategies and technologies, whose performance depends on the context of their application. On the other hand, improper use can have significant negative effects on both comfort and energy requirements, such as increased glare and cooling loads. To ensure proper use, designers need tools that model the dynamic nature of daylight and accurately predict performance with respect to a multitude of performance criteria, extending beyond comfort and energy to include aesthetics, cost, security, safety, etc.

title	The visual harmony between new and old materials in the restoration of historical architecture: A study of computer simulation
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	In the research of historical architecture restoration, scholars respectively focus on the field of architectural context and architectural archeology (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000) or on architecture construction and the procedure of restoration (Shi, 1988, 1989; Chiu, 1990). How to choose materials and cope with their durability becomes an important issue in the restoration of historical architecture (Dasser, 1990; Wang, 1998).In the related research of the usage and durability of materials, some scholars deem that, instead of continuing the traditional ways that last for hundreds of years (that is to replace new materials with old ones), it might be better to keep the original materials (Dasser, 1990). However, unavoidably, some of the originals are much worn. Thus we have to first establish the standard of eliminating components, and secondly to replace identical or similar materials with the old components (Lee, 1990). After accomplishing the restoration, we often unexpectedly find out that the renewed historical building is too new that the sense of history is eliminated (Dasser, 1990; Fu, 1997). Actually this is the important factor that determines the accomplishment of restoration. In the past, some scholars find out that the contrast and conflict between new and old materials are contributed to the different time of manufacture and different coating, such as antiseptic, pattern, etc., which result in the discrepancy of the sense of visual perception (Lee, 1990; Fu, 1997; Dasser, 1990).In recent years, a number of researches and practice of computer technology have been done in the field of architectural design. We are able to proceed design communication more exactly by the application of some systematic softwares, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and so on (Lawson, 1995; Liu, 1996). The application of computer technology to the research of the preservation of historical architecture is comparatively late. Continually some researchers explore the procedure of restoration by computer simulation technology (Potier, 2000), or establish digital database of the investigation of historical architecture (Sasada, 2000; Wang, 1998). How to choose materials by the technology of computer simulation influences the sense of visual perception. Liu (2000) has a more complete result on visual impact analysis and assessment (VIAA) about the research of urban design projection. The main subjects of this research paper focuses on whether the technology of computer simulation can extenuate the conflict between new and old materials that imposed on visual perception.The objective of this paper is to propose a standard method of visual harmony effects for materials in historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example).There are five steps in this research: 1.Categorize the materials of historical architecture and establish the information in digital database. 2.Get new materials of historical architecture and establish the information in digital database. 3.According to the mixing amount of new and old materials, determinate their proportion of the building; mixing new and old materials in a certain way. 4.Assign the mixed materials to the computer model and proceed the simulation of lighting. 5.Make experts and the citizens to evaluate the accomplished computer model in order to propose the expected standard method.According to the experiment mentioned above, we first address a procedure of material simulation of the historical architecture restoration and then offer some suggestions of how to mix new and old materials.By this procedure of simulation, we offer a better view to control the restoration of historical architecture. And, the discrepancy and discordance by new and old materials can be released. Moreover, we thus avoid to reconstructing ¡§too new¡¨ historical architecture.

title	An application of the REN manager in the field of housing management
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	There is a continuous and urgent need for standardisation of discussion about quality of real estate. On behalf of this discussion, a tool called REN Manager has been developed. REN is an abbreviation of Real Estate Norm, a client-oriented tool for measuring, planning and communication in the field of housing management. The development of the REN Manager is a continuation of REN research-project. In this paper we start with an introduction of the REN research project. Further we focus on the application of the REN tool in the field of housing management as part of a set of tools for strategic portfolio management. After this introduction we will elaborate more about the REN and the underlying analyses. One of the essential functions of REN is the match between the demanded and offered performance of a dwelling estate. By several surveys among tenants the relevant aspects and parameters are determined. These parameters are related to the performance level of a dwelling as well as to the weight of these levels. This part of the paper deals with the results of these analyses and the problems involved in the method used. The results are used as the input for the REN Manager. At the end we will discuss the functionality of the REN Manager as a decision support system on both operational level (matching) and strategic portfolio management (allocation of investment).

title	From Forming to Transforming
source	International Conference on Generative Art
summary	The ancient codes of harmony stem from the human vision of the complexity of nature. They allow us to think the possible, to design it and to perform its realization. The first gesture of every designer is to take, in a new application that is born from a need the opportunity to experiment with a possible harmonic code. And to operate in the evolution of the project so that this code buds and breeds beauty as a mirror of the complexity and wonder of nature. In this design activity, project after project, every architect builds his own code. This is strongly present in diverse ways in every architect. The code of harmony born from the attention of every man to the complexity of nature, manifests itself in interpretation, which is logical and therefore feasible, of the laws of formalization of relationships. Every interpretation is different and belongs to the oneness of every architect. Every interpretative code stems from, and reveals, our approach to the world, our cultural references, our history, our present and the memory of our past. Each idea is born as a representation of the interpretative code that is a cryptic and subjective code, even if it refers as constant to history of man. Generative art is the maximum expression of this human challenge: it traces a code as a reference to the complexity of nature, and it makes it feasible. So man is the craftsman of the possible, according to the laws of the natural harmony. What does a code of the harmony contain? As for all codes it contains some rules that trace certain behaviors. It is not therefore a sequence, a database of events, of forms, but it defines behaviors: the transformations. To choose forms and to put them together is an activity that can also resemble that of a designer, but essentially it is the activity of the client. The designer does not choose forms but operates transformations, because only by doing so can he put a code of harmony into effect. Between transforming and choosing forms one can trace the borderline between architects and clients, between who designs and who chooses the projected objects. This difference must be reconsidered especially today because we are going toward a hybridization in which the client wants to feel himself a designer, even if he only chooses. And the designer, using sophisticated tools, works as chooser between different solutions, in practice as a client. To design, to create through transformations is, however, an activity that takes time. The generative design, building a usable and upgradable code, makes time virtual and therefore allows the architect, even in a speeded-up world as today is, to design and reach levels of complexity that mirror the complexity of nature and its beauty.

title	Development of an intuitive 3D sketching tool
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	3D sketching is a confusing description of an architectural design means. It is confusing, or even worse apparently wrong, because traditional sketching is inherently a two dimensional activity. Though the final stages of design are currently well support by CAD packages, almost every architect prefers paper and pencil for the early sketching phases. The challenge is to develop a (computer supported) design tool that is as direct and intuitive as paper and pencil. The computer enables us to directly map our spatial mental model into 3D rendered images. As such a new kind of design means is created which is best indicated as an intuitive 3D sketching tool. Within the VR-DIS research programme of the Design Systems group of the Eindhoven University of Technology a tool named DDDoolz has been developed as an experimental 3D sketching tool. This paper will report on the preliminary phase in which several input devices such as mouse, bird and voice were tested. For this purpose simple prototype applications were implemented. Building upon these experiences a functional brief was defined for the sketching tool. The system design will be elaborated in this paper using OO schema techniques. Because of its limited yet powerful functionality, a comprehensive system description can be presented. The application has been used in a first years CAD course. Students’ experiences will be discussed demonstrating the strengths and weaknesses of DDDoolz. In conclusion, a list of improvements will be presented and the future directions are indicated that will be followed in regard of the continuing research on design and decision support tools.

title	Refurbishment of building services engineering systems under a collaborative design environment
source	Automation in Construction 9 (2) (2000) pp. 185-196
summary	In this paper hypermedia is suggested as a suitable paradigm to represent the design processes associated with a shopping center refurbishment project. In addition, by adopting a collaborative design model, the paper makes reference to such factors as synchronous vs. asynchronous and active vs. passive modeling. Concepts in complex problem solving are also explored such as the soft system methodology as well as the application of agent-based decision support systems. Identification of primary information elements and analysis of the relations between these elements indicates that the flow of design information may be readily represented in hypermedia which features nonlinear characteristics in organizing information. The justification of developing a hypermedia tool to cope with changing conditions of a complex design problem instead of providing a solution for a predetermined problem is also argued. The paper illustrates the complex nature of collaborative design process with reference to a case study associated with the building services systems design for a Hong Kong Housing Authority refurbishment project.

title	Towards generic representations of designs formalised as features
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	Feature-Based Modelling (FBM) is an information modelling technique that allows the formalisation of design concepts and using these formal definitions in design modelling. The dynamic nature of design and design information calls for a specialised approach to FBM that takes into account flexibility and extensibility of Feature Models of designs. Research work in Eindhoven has led to a FBM framework and implementation that can be used to support design.. Feature models of a design process has demonstrated the feasibility of using this information modelling technique. To develop the work on FBM in design, three tracks are initiated: Feature model descriptions of design processes, automated generic representation recognition in graphic representations, and Feature models of generic representations. The paper shows the status of the work in the first two tracks, and present the results of the research work.
