title	Advanced Lighting Simulation in Architectural Design in the Tropics
doi	https://doi.org/10.52842/conf.caadria.1999.429
source	CAADRIA '99 [Proceedings of The Fourth Conference on Computer Aided Architectural Design Research in Asia / ISBN 7-5439-1233-3] Shanghai (China) 5-7 May 1999, pp. 429-441
summary	This paper outlines a two years research program that the team attempted to apply one of the most powerful computational lighting simulation software RADIANCE to assist in daylighting design of an actual building in the tropics. The validation studies, which were carried out in the Asian Civilisation Museum (ACM) in Singapore, show that Radiance can be used to predict the internal illuminance with a high degree of accuracy under overcast sky conditions without external obstruction. The experimental application of Radiance to daylighting investigation of the ACM further supports its capabilities as well as its accuracy. Using Radiance to study two daylighting control options (curtains and louvers), it can be found that louvers are more effective than curtains as daylighting control devices, and that the angle of the louvers has more effect than their reflectance on daylight penetration and distribution.

title	FULL-SCALE MODELING FOR THE LIGHTING DESIGN OF A NEW PAVILION AT THE VENICE BIENNALE
source	Full-scale Modeling and the Simulation of Light [Proceedings of the 7th European Full-scale Modeling Association Conference / ISBN 3-85437-167-5] Florence (Italy) 18-20 February 1999, pp. 51-56
summary	The research which is presented in this paper is related to a lighting topic and part of an architectural project for a pavilion at the Biennale of Venice, used for modern art exhibitions. The building is located along a Venetian canal: the roof form is curved in a way to allow daylight, reflected by the water, to penetrate in the lower part of the building, determining the atmosphere for the sculpture exhibition. In the upper part of the building, where the rooms have a barrel-shaped roof, we want to provide good diffuse lighting to emphasise the quality of the materials and colors of paintings. Starting point is a study of lighting techniques related to a temporary exhibition of modern art. Special attention will be paid to some considerations concerning the question of conservation, the integration of artificial lighting and daylighting, the modeling effects of light and its color performance as well as the effect of light. The study has been carried out testing (full-) scale models in the Lighting Laboratory at the University College of London.

title	VDU WORK IN DIFFERENT LIGHTING CONDITIONS
source	Full-scale Modeling and the Simulation of Light [Proceedings of the 7th European Full-scale Modeling Association Conference / ISBN 3-85437-167-5] Florence (Italy) 18-20 February 1999, pp. 7-28
summary	In order to avoid the disadvantages of purely subjective methods in a technical evaluation of daylight and artificial light systems, the Bartenbach LichtLabor developed new test methods which can determine objectively and quantitatively the visual or psycho-physiological stress connected with VDU work [1], depending on different lighting conditions. Daylight and artificial lighting systems were tested with these methods and compared by using the performances achieved by the test subjects. Some highly significant differences in performance done under the individual lighting systems became apparent and demonstrated that the visual stress or the physical or physiological fatigue from an ergonomic viewpoint depends largely on the lighting conditions at the workplace. This holds true for daylight systems (glare protection, re-directing lamellae, clear window as a control condition) as well as for purely artificial lighting systems where especially the choice of color temperature of the light and the used control gear (conventional or electronic) determine the resulting performance. Optimized lighting also positively affects the productivity and economicy for the design of workplaces that take the human factor into account.

title	Computer Daylight Simulation Systems: An Experimental Evaluation
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 115-120
summary	This paper investigates Daylight Simulation Systems in computer visualization programs. Computer visualization has provided qualitative appearance in architectural presentation. There are two aspects, one objective and another subjective, that should be considered in lighting simulation. The objective aspect is concerned with accurate prediction of daylight levels. The subjective aspect is associated with the evaluation of lighting quality. The objective aspect of lighting has often been neglected by visualization designers during the process of simulation. The relevant concepts of lighting to ensure accurate simulation techniques have been defined in order to highlight and resolve the dilemma of accurate lighting visualization. The interactive relationship between material simulation and lighting simulation has also been investigated. In addition, there is a discussion to determine how realistic and artistic the current approaches on lighting simulation are for architectural design presentation. This paper has attempted to provide guidance for the future development of visualization programs and information on innovative ways to accommodate computer visualization for architectural usage and needs.

summary	Daylighting lets to reveal 3D plastic imagination of building and architectural form. Being of the main time for perception of architecture, daylight helps to solve two principal questions: volumetric-spatial and coloristic solution. Experience of the work shows, that modelling in the natural light on the earliest step helps to understand chosen design comparatively and to take essential correction operatively.

title	A practical analytic model for daylight
source	Proceedings of the SIGGRAPH annual conference on Computer graphics, 91-100
summary	Sunlight and skylight are rarely rendered correctly in computer graphics. A major reason for this is high computational expense. Another is that precise atmospheric data is rarely available. We present an inexpensive analytic model that approximates full spectrum daylight for various atmospheric conditions. These conditions are parameterized using terms that users can either measure or estimate. We also present an inexpensive analytic model that approximates the effects of atmosphere (aerial perspective). These models are fielded in a number of conditions and intermediate results verified against standard literature from atmospheric science. Our goal is to achieve as much accuracy as possible without sacrificing usability.

title	On multi body systems simulation in product design
source	KTH Stockholm
summary	The aim of this thesis is to provide a basis for efficient modelling and software use in simulation driven product development. The capabilities of modern commercial computer software for design are analysed experimentally and qualitatively. An integrated simulation model for design of mechanical systems, based on four different "simulation views" is proposed: An integrated CAE (Computer Aided Engineering) model using Solid Geometry (CAD), Finite Element Modelling (FEM), Multi Body Systems Modelling (MBS) and Dynamic System Simulation utilising Block System Modelling tools is presented. A theoretical design process model for simulation driven design based on the theory of product chromosome is introduced. This thesis comprises a summary and six papers. Paper A presents the general framework and a distributed model for simulation based on CAD, FEM, MBS and Block Systems modelling. Paper B outlines a framework to integrate all these models into MBS simulation for performance prediction and optimisation of mechanical systems, using a modular approach. This methodology has been applied to design of industrial robots of parallel robot type. During the development process, from concept design to detail design, models have been refined from kinematic to dynamic and to elastodynamic models, finally including joint backlash. A method for analysing the kinematic Jacobian by using MBS simulation is presented. Motor torque requirements are studied by varying major robot geometry parameters, in dimensionless form for generality. The robot TCP (Tool Center Point) path in time space, predicted from elastodynamic model simulations, has been transformed to the frequency space by Fourier analysis. By comparison of this result with linear (modal) eigen frequency analysis from the elastodynamic MBS model, internal model validation is obtained. Paper C presents a study of joint backlash. An impact model for joint clearance, utilised in paper B, has been developed and compared to a simplified spring-damper model. The impact model was found to predict contact loss over a wider range of rotational speed than the spring-damper model. Increased joint bearing stiffness was found to widen the speed region of chaotic behaviour, due to loss of contact, while increased damping will reduce the chaotic range. The impact model was found to have stable under- and overcritical speed ranges, around the loss of contact region. The undercritical limit depends on the gravitational load on the clearance joint. Papers D and E give examples of the distributed simulation model approach proposed in paper A. Paper D presents simulation and optimisation of linear servo drives for a 3-axis gantry robot, using block systems modelling. The specified kinematic behaviour is simulated with multi body modelling, while drive systems and control system are modelled using a block system model for each drive. The block system model has been used for optimisation of the transmission and motor selection. Paper E presents an approach for re-using CAD geometry for multi body modelling of a rock drilling rig boom. Paper F presents synthesis methods for mechanical systems. Joint and part number synthesis is performed using the Grübler and Euler equations. The synthesis is continued by applying the theory of generative grammar, from which the grammatical rules of planar mechanisms have been formulated. An example of topological synthesis of mechanisms utilising this grammar is presented. Finally, dimensional synthesis of the mechanism is carried out by utilising non-linear programming with addition of a penalty function to avoid singularities.

title	Integrated Lighting System Assistant
source	Eindhoven University of Technology
summary	The aim of the design project described in this thesis is to design a tool to support the building design process. Developing a design is considered to be a wicked problem because it goes beyond reasonable or predictable limits. Consequently, in this design project we address two wicked problems simultaneously: a double wicked problem. The two wicked problems concerned are the design of Design Decision Support System [DDSS] and the conceptual design of office lighting systems. To get a handle on the first wicked problem, two workshops were organised to meet the possible future users and to create a common basis for the tool to be developed. To tackle the wickedness of the second problem, an office lighting model and performance evaluation method were developed and implemented in a new prototype computer system: Integrated Lighting System Assistant [ILSA]. The workshops have proven to be a good source of feedback and an essential link to daily practice. The ILSA prototype shows that it is possible to implement the lighting model and evaluation method into a working prototype that can support architects in making decisions for the early design stage in the field of integrating daylight and artificial lighting.

summary	3D modeling and computer simulations provide new ways for architecture students to study the relationship between the design and construction of buildings. Digital media help to integrate and expand the content of courses in drafting, construction and design. This paper describes computer-based exercises that intensify the students’ experience of construction in several courses from sophomore to senior level. The courses integrate content from drafting and design communication, construction, CAD, and design. Several techniques are used to strengthen students’ awareness and ability in construction. These include: · Virtual design - build projects in which students construct 3D CAD models that include all elements that are used in construction. · Virtual office in which several students must collaborate under the supervision of a student acting as project architect to create a 3D CAD model and design development documents. · Virtual sub-contracting in which each student builds a trade specific 3D CAD model of a building and all of the trade specific models must be combined into a single model. · Construction simulations (4D CAD) in which students build 3D CAD models showing all components and then animate them to illustrate the assembly process. · Cost estimating using spreadsheets. These techniques are applied and reapplied at several points in the curriculum in both technical laboratory courses and design studios. This paper compares virtual construction methods to physical design – build projects and provides our pedagogical arguments for the use of digital media for understanding construction.

title	THE EXPERIENCE OF SPACE IN FULL-SCALE MODELS AND VIRTUAL REALITY

summary	Do we experience the size and character of virtual spaces in the same way as real spaces? What impact has the meaning of a space, i.e. furniture and other clues to the use of a space, on our experience of it? This paper describes an experiment where the participants could navigate through a room, first on desktop-VR, then in full-scale VR (in a CAVE) and finally in a full-scale model. In a first phase the room was empty and only defined through walls, windows and doors. Later on furniture was added as well as colors and textures. The experiment was a pilot study and threw light on some questions which we intend to develop in further investigations. It showed that the participants used building components like doors and windows and furniture in the presentation on desktop VR for their estimation of the size of the room. In the CAVE and in the full-scale model the participants' bodies were the measure for their estimations. The experiment also hinted at that color and texture had an impact on the experience of size.

summary	Computer graphics have developed efficient techniques for visualisation of the real world. Many of the algorithms have a physical basis, such as computational models for the light and the shadow, models of real objects (buildings, mountains, roads and so on) and the simulation of natural phenomenon. Now computer graphics techniques provide the virtual world with a perception of three dimensions. The concept of the virtual world and its technology have been expanding and intensifying in recent years. Almost everything in the real world has been simulated in virtual world. When it comes to a terrain model, what we need is labour and time. But now it is possible to simulate terrain like the real world using fractals in computer graphics with a very small program and small data set. This study aims to show how to build a real world impression in the virtual world. In this paper the authors suggest a landscape design method and show the results of its application.

summary	In a terms of studying and practical design a sufficient experience of analytic work of our lab shows, that the view of suggesting scheme on the same kind of process development is accompanied by sadden mistakes or conscious inaccuracies.Traditional conventions of architectural models same times with no paying attention to scale and size may drive to cause of distortion from the points of view to them. Power and possibilities of modern CAD initiates same sort of temptations and errors. For our point of view, solving the above problems is having same restrictions, one of which, may be – providing a visual coincidence of the videoframes of building site and it’s model done whether by small scale modelling or CAD. According to our practice a different methods of superimposing of real and designing spaces are shown in this article.

source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 611-619
summary	Computer applications in design have pursued two main development directions: analytical modelling and information technology. The former line has produced a large number of tools for reality simulation (i.e. finite element models), the latter is producing an equally large amount of advances in conceptual design support (i.e. artificial intelligence tools). Nevertheless we can trace rare interactions between computation models related to those different approaches. This lack of integration is the main reason of the difficulty of CAAD application to the preliminary stage of design, where logical and quantitative reasoning are closely related in a process that we often call 'qualitative evaluation'. This paper briefly surveys the current development of qualitative physical models applied in design and propose a general approach for modelling physical behaviour by means of Bayesian network we are employing to develop a tutoring and coaching system for natural ventilation preliminary design of halls, called VENTPad. This tool explores the possibility of modelling the causal mechanism that operate in real systems in order to allow a number of integrated logical and quantitative inference about the fluid-dynamic behaviour of an hall. This application could be an interesting connection tool between logical and analytical procedures in preliminary design aiding, able to help students or unskilled architects, both to guide them through the analysis process of numerical data (i.e. obtained with sophisticate Computational Fluid Dynamics software) or experimental data (i.e. obtained with laboratory test models) and to suggest improvements to the design.

title	Digital Simulation and Inferential Systems
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 87-92
summary	From the perspective of logic and epistemological formalizations, the processes for data elaboration relate reasoning schemes to inferential operations which enable the building, understanding and setting of criteria for knowledge validation in a complex sequence. Cognitive operations do not belong exclusively to the field of discourse thinking,' they also apply to the field of perception. Specially in the area of images, there exist inferences which are expressed and operated through other media. A particular aspect is the one of digital simulation and the links established with inferential systems. Although they are not the same thing, since simulation is a cognitive methodology, both are based on similar logic principles. It is obviously necessary to build budget or referential frameworks to support practices deriving from the graphic/digital culture. Thus, they could act as judgement instruments in order to analyze and recognize changes in project, space, morphological and expressive paradigms, and to overcome the instrumental and reductionist bias usually found in the development of these practices. The present work is oriented in this direction, studying relations established among digital simulation, inferential systems, cognitive elaboration and scientific knowledge validation. We aim at exploring and researching into the affinity, links and differences between simulation and analogic-abductive inferential systems so as to characterize: 1.) The concept of digital simulation, not only due to its strong reproductive power but to its inherent referential, cognitive and poetic functions. 2.) The nature of replacing actions projected by simulation with respect to reality in order to produce a representative act the innovative and creative power of simulation, directed both to the past and the future. 3.) The dimensions of prevision and interpretation where simulation develops its theoretical and empirical attitudes and the idea that simulation derives from the combination of hypothesis and experimentation.

title	Information Architecture: Basics of CAAD and its future
source	Basel: Birkhaeuser
summary	With increasing intensity, CAAD (Computer Aided Architectural Design) is determining the daily work of today's architectural offices. Computers allow complex designs to be visualised and altered with great speed and accuracy; three-dimensional models can be created with simulation and animation possibilities, and links to the World Wide Web provide access to a flow of information. The author develops his thesis that these aspects do not just enable the creative process to be optimised in a quantitative sense but also qualitatively. Alongside the spatial and time dimensions, the new electronic possibilities provide a fifth dimension in architecture.

title	Integrated Computational Analysis of the Visual Environment in Buildings
source	Carnegie Mellon University, Pittsburgh
summary	Despite significant advances in the area of computational support for lighting design, lighting simulation tools have not been sufficiently integrated into the lighting design process. There is a significant body of designers who rely solely on their individual experience and do not use predictive simulation tools. Even when simulation tools are utilized, it is for design verification or presentation rather than for design support. A number of factors are thought to contribute to this lack of integration of simulation tools into the design process: a) Most existing tools rely on the problematic assumption implying the appropriateness of simplified models for the less complex early design and detailed simulation for the more complex later stages of design; b) They do not support an active exploration of design variables to satisfy desired performance criteria; c) They are not integrated with other building performance simulation models. This thesis addresses the above shortcomings by contributing to the field of visual analysis in the following areas, pertaining to the development of active, integrated design and performance simulation environments: - Implementation of a consistent and coherent, physically-based modeling approach, combining radiosity and ray-tracing methods for the simulation of light propagation. - Provision of design support both in terms of evaluation support for interpreting large amounts of computed data with diverse performance indices, and in terms of active design support to explore the relationships between the design variables and performance indices. - Integration of the lighting simulation module within a larger software environment (SEMPER) for the prediction and evaluation of multiple performance indicators (for energy, light, acoustics, etc.) in buildings.

title	APPLICATION OF SPATIAL DESIGN ABILITY IN A POSTGRADUATE COURSE
source	Full-scale Modeling and the Simulation of Light [Proceedings of the 7th European Full-scale Modeling Association Conference / ISBN 3-85437-167-5] Florence (Italy) 18-20 February 1999, pp. 75-82
summary	Spatial Design Ability (SDA) has been defined by the author (1983) as the capacity to anticipate the effects (psychological impressions) that architectural spaces or its components produce in observers or users. This concept, which requires the evaluation of spaces by the people that uses it, was proposed as a guideline to a Masters Degree Course in Architectural Design at the Universidad Autonoma de Aguascalientes in Mexico. The theory and the exercises required for the experience needed a model that could simulate spaces in terms of all the variables involved. Full-scale modeling as has been tested in previous research, offered the most effective mean to experiment with space. A simple, primitive model was designed and built: an articulated ceiling that allows variation in height and shape, and a series of wooden panels for the walls and structure. Several exercises were carried out, mainly to experience cause -effect relationships between space and the psychological impressions they produce. Students researched into spatial taxonomy, intentional sequences of space and spatial character. Results showed that students achieved the expected anticipation of space and that full-scale modeling, even with a simple model, proved to be an effective tool for this purpose. The low cost of the model and the short time it took to be built, opens an important possibility for Institutions involved in architectural studies, both as a research and as a learning tool.

title	CAD Interfaces to the ARROW Manufactured Product Server
source	Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 1-11
summary	The UK national project ARROW (Advanced Reusable Reliable Objects Warehouse) provides an Internet based framework through which it is possible to identify any of a range of manufactured products meeting specific design criteria. This open framework (based upon the IAI's IFCs) provides a mechanism for users to search for products from any participating manufacturer or supplier based both on specific attributes of a product or on any of the textual descriptions of the product. The service returns the closest matching products and allows the user to navigate to related information including manufacturer, suppliers, CAD details, VR displays, installation instructions, certificates, health and safety information, promotional information, costings, etc. ARROW also provides a toolkit to enable manufacturers and suppliers to more easily map and publish their information in the format utilised by the ARROW system. As part of the ARROW project we have examined the ability to interface from a design tool through to ARROW to automatically retrieve information required by the tool. This paper describes the API developed to allow CAD and simulation tools to communicate directly with ARROW and identify appropriate manufactured information. The demonstration system enables CAD systems to identify the closest matching manufactured product to a designed product and replacing the designed product with the details supplied by the manufacturer for the manufactured product as well as pulling through product attributes utilised by the design application. This paper provides a description of the ARROW framework and issues faced in providing information based upon standards as well as containing information not currently modelled in public standards. The paper looks at issues of enabling manufacturers and suppliers to move from their current world-view of product information to a more data-rich and user accessible information repository (even though this enables a uniform comparison across a range of manufacturer's products). Finally the paper comments on the likely way forward for ARROW like systems in providing quality information to end users.

summary	This paper proposes principles for the design of human-centered, anthropic cyberspaces. Starting with a brief examination of our cognitive use of space, it suggests that we address cyberspace as an extension of our mental space. The paper procedes with twelve concepts based on scientific and cultural observations with respect to individual cognition and social interaction. These concepts are general - not specific to any culture or technology in the accompanying arguments the author expands on these concepts illustrating them with examples taken from conventional and electronic media, space and cyberspace the author hopes with these conjectures to begin a discussion on the anthropology of space and its emulation.
