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	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	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	Working with the Bits and Digits of Lighting Studies in Architectural Education
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. 231-234
doi	https://doi.org/10.52842/conf.ecaade.2000.231
summary	The study investigates learning and pedagogical differences between using physical models and computational simulations for architectural lighting design studies. The vehicle of the study is a real life architectural project for a church building. The research reveals that users of physical models were more aware of the need for technical knowledge whilst the users of simulation software are more contended with the virtual results without evaluating them critically. Preliminary results not only confirm the long established view that the computational simulation lacks the tactile quality for architectural understanding; worst still, it gives inexperienced users illusions of knowledge and claims of understanding. To further validate the results, works involving a larger sample set and a more comprehensive design program should be conducted.

title	Desktop Radiance A New Tool for Computer-Aided Daylighting Design
source	ACADIA Quarterly, vol. 19, no. 2, pp. 9-11
doi	https://doi.org/10.52842/conf.acadia.2000.009
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	Virtual Analogy and Architecture
source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 69-73
doi	https://doi.org/10.52842/conf.ecaade.1999.069
summary	Our fashion of thought is dialogic in its way to use simultaneously logic- mathematics and analogical approaches (Morin, 1986). The analogy works as well at the level of the unconscious by the construction of an analogon that permits us to recognise a face between thousand of others, despite changes intervened in time; as consciously where by an effort of constructive analogy, we establish bridges between different events or domains giving to the design a new lighting that puts it on the way to a solution. For this reason visual approach acquires a great importance in the establishment of similitude in conception. Many testimonies of scientists, philosophers, artists confirm this observation about their creative work, while underlining the danger of no founded analogies. In current life, analogy brings a support of likeness to the daily conversations, and the possibility to advance in the dialogue by a chaining of analogies having for objective to strengthen the speech.

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.

summary	Ever since the advent of computer graphics in the sixties, computer-aided architectural design (CAAD) has made a great impact in architectural education and practice. Its central role as a new media for the representation and analysis of designs will ensure that it will continue to do so. The teaching and research in CAAD in Asia have also been growing in scope and in quality. In the 21st century, the challenges of architectural education and practice in the new millennium will open up new fronts in CAAD research. This conference is an important platform to evaluate the challenge and opportunities and will enable researchers to exchange ideas and collaboration in projects with specific relevance to CADD for Asia. This compilation of 48 papers were elected through a blind review by an international panel and presented at the conference in Singapore on 18 - 19 May 2000. The chapters are organised according to the main topics covered by the conference -- Collaborative Design, Simulation, Design Education, Knowledge Representation, Design Process, Information Systems, Design Tools, Virtual Reality and Computer Media. The Collaborative Design section consists of papers which deal with Collaborative Design Process interfaces to databases, Collaborative Design System for Citizen Participation, Team Awareness in Collaboration and Computer Environment for supporting Design Collaboration. The Simulation section deals with lighting studies, colour assessment, simulation of urban growth patterns, dynamic simulations in buildings and way-finding.

title	Applying Daylighting Simulation in Architectural Studio Education

summary	Computer generated simulation results are not necessarily valid design solutions. In some cases, unscientific “simulation” applications have misled designers to believe the “illusion” rendered by the system. This paper presents two case studies to highlight the pedagogy of architectural daylighting simulation. Both are located in Hong Kong’s highdensity urban context. Hong Kong is a small city, covering 1,097 square km with a population of 6.8 million. Mountains and hills dominate the topography, and more than 70% of the land is reserved for country parks. Property constraints encourage dense, high-rise construction and building on steep slopes. This creates a complex environment for daylighting design. Although the Buildings Ordinance specifies minimum standards for natural light and ventilation, residents have complained about the deterioration of their lighting condition in recent years. Challenged by the constraints imposed by Hong Kong’s physical environment, there is a need for students and professionals to explore computer simulation to integrate daylighting strategy into architectural and urban design.

doi	https://doi.org/10.52842/conf.caadria.2000.107
summary	This pilot research attempts to investigate differences in process between lighting study using physical model and computational simulation. A Physical modelling team, a computational modelling team, and a monitoring and tracking team were formed to process and monitor the research by a defined workflow of the design process. Using a time schedule technique, the procedures of each of the two methods were tracked. The research reveals that the research team favoured physical modelling for its ease of use and computational simulation for its flexibly. And that the users of physical models were more aware of the need for technical knowledge whilst the users of simulation software are more contended with the virtual results without evaluating them critically. In addition, the experiment also shows that the feedback mechanism of the physical modelling process is instant, continues and intuitive, whereas that of the computational process is discrete. Preliminary results not only confirm the long established view that the computational process lacks the tactile quality required for architectural understanding; worst still, it gives inexperienced users an illusion of knowledge and claims of understanding. Due to limitations of time, the research captures only the feasibility stage of the design process, further works involving a more comprehensive design program should be conducted.
