summary	The Generative Design System [GDS] presented in this paper was developed to assist designers in researching low-energy architecture solutions. The GDS has the capability to evolve architectural forms that are energy-efficient, while complying to design intentions expressed by the architect, and responding to conflicting objectives. To achieve this evolutionary development, the system integrates a search and optimization method [Genetic Algorithm], a building energy simulation software [DOE2.1E], and Pareto multicriteria optimization techniques. The GDS adaptively generates populations of alternative solutions, from an initial schematic layout and a set of rules and constraints designed by the architect to encode design intentions. The two conflicting objective functions considered in this paper are maximizing daylighting use, and minimizing energy consumption for conditioning the building. The GDS generated an uniformly sampled, continuous Pareto front, from which six points were visualized in terms of the proposed architectural solutions.

title	IMPROVING NEURAL NETWORK MODELS OF PHYSICAL SYSTEMS THROUGH DIMENSIONAL ANALYSIS
source	Journal of Applied Soft Computing 2(4): 283-296.
summary	The paper presents a technique for generating concise neural network models of physical systems. The neural network models are generated through a two-stage process. The first stage uses information embedded in the dimensions or units in which the data is represented. Dimensional analysis techniques are used initially to make this information explicit, and a limited search in the neural network architecture space is then conducted to determine dimensionless representations of variables/parameters that perform well for a given model complexity. The second stage uses information available in the numerical values of the data to search for high-level dimensionless variables/parameters, generated from simple combinations of dimensionless quantities generated in the first stage and which result in concise neural network models with improved performance characteristics. The search for these high-level dimensionless variables/parameters is conducted in an enhanced representation space using functional link networks with flat or near flat architectures. The use and effectiveness of the technique is demonstrated for three applications. The first is the design and analysis of reinforced concrete beams, which is representative of the class of problems associated with the design and analysis of composites. The second is the classical elastica problem, for predicting non-linear post-buckled behaviour of columns and the third, the analysis of a bent bar under a specified combination of loads.

title	Types and precedents in design guidance

summary	In recent years Dutch secondary education has been undergoing a fundamental change due to the introduction of new didactic approaches which relate strongly to ongoing social and technological developments. This affects existing school buildings, the majority of which is quite conventional in spatial terms and is characterized by limited flexibility and transformability. Consequently, most schools require extensive modifications in their spatial and building structure. The requirements underlying these modifications are not stable. Many schools have become interested in experimental ideas that may require inevitably further changes in the buildings. The paper considers the continuous transformation of Dutch school buildings with respect to their typology: by correlating new design briefs to building types rather than their instances we arrive at general guidelines that can be easily adapted to specific cases. To achieve this, the types are analysed with respect to geometry, topology and zoning. The results of the analysis describe the affordances of each type in terms of general flexibility, transformability and adaptability, as well as in relation to generic briefs. They also provide an explanation of the historical evolution of the types and the means for relating primary characteristics to local configurations, thereby allowing the accurate description of hybrid instances. The descriptions and analysis of buildings are organized into a polyhierarchical multilevel database that supports typological abstraction and offers several starting points (at various abstraction levels) for matching a new brief to an existing building. This enriches the development of the brief or a design solution with explicit, specific information derived from concrete precedents with known form, structure, behaviour and performance.

title	Performance Evaluation of 3D-Model CAAD Implementation in Dutch Architecture Firms
source	South Bank University [In cooperation with Hogeschool van Arnhem en Nijmegen - The Netherlands]
summary	The principal theme of this research is to provide information regarding the implementation of 3D Model CAAD, CAAD system which uses 3D Drawing Production Method (DPM) instead of 2D DPM This research is focused on its implementation in architecture firms and on justifies its performance and investment value. Principally there are two evaluations conducted in this research. First evaluation aimed to justify 3D-Model CAAD influence on design process and the second is investment evaluation which aimed to provide information for current and prospective user regarding their current and future investment on 3D-Model CAAD. The results of the evaluations are: 3D Model CAAD has improved performance through efficiency on time and cost of design process also improvement on design quality. However correlation between the use of 3D-Model C.4AD and better performance, while tested using Chi-Square Test, is not significantly. This fact indicates that there are some other strong factors to influence design performance. Second, 3D-Model CAAD, according the Importance-Performance Map is positioned at top right quadrant which categorised as 'keep the good work' which means it has good investment value.

title	DIFFERENCE BETWEEN EXPERT AND NOVICE DESIGNERS: AN EXPERIMENTAL STUD
source	Human Behaviour in Design, edited by U Lindemann, Springer, Berlin, pp 42-51.
summary	This chapter investigates the differences in performance between an expert and a novice in terms of their respective strategic knowledge. We examined conceptual design protocols of an expert and a novice, and found that the expert’s cognitive activity and productivity in the design process were almost three times as high as the novice's. The possible reason for this is the difference in their strategic knowledge. The expert’s cognitive processing is structured such that it stays within the limits of human short term memory. This provides empirical evidence for a different strategic knowledge that may be developed with experience. The expert's strategic knowledge allows him to use a smaller number of processes and to form different groupings of processes.

title	The Role of CAD in Environmental Building Science

doi	https://doi.org/10.52842/conf.caadria.2003.487
summary	The fundamental requirement of all building design is the provision of shelter from the external climate and, if possible, the modification of environmental factors generated by this climate to create an internal environment suitable for human comfort. The environmental design strategies of modifying climate derive from the requirements of creating human comfort in buildings, using the elements of the natural climate which vary throughout the year depending upon the prevailing climatic conditions. Environmental Building Science (EBS) research and practice has investigated various techniques to increase architects' performance in environmental building design. These technical design options are also available to architects to take advantage of the external environment. Most environmental design techniques rely on convectional forms of passive environmental design, and building material and system. But it hardly begins to address the more complex demands of environmental building design issues in the buildings. Particularly, testing environmental design techniques against physical models requires much input data which is not available in the early design stages, and is time consuming to use. This forces architects to work with many design parameters that are not compatible with their activities. It is consequently difficult to observe the interrelation of design techniques with design development. The most important role of Computer Aided Design (CAD) is to integrate wider varieties of input data requirements, modelling with EBS properties, output representations with EBS knowledge and assistance tools for optimisation tasks in environmental design issues.

summary	Working with big models requires a good balance between the technical requirements of the model and the technical requirements of the user. Although every virtual model, whether it is 2d, 3d or 4d, may be regarded as a particular form of a general data base, it is clear that is not, at the present time, a very flexible data base. It does not behave like a relational data base that can be inspected in a flexible way. On the contrary, it has a rigid structure, a hierarchical structure that is well suited for performance but is badly suited for navigating through the data and gathering derived information. These are well known disadvantages and advantages, related to the evolution of the data base software that has moved, in the last 30 years, from a hierarchical to a relational structure. These considerations are relevant for any kind of architectural or engineering model. But are particularly pertinent in the case of the model of a city where everything must have its place, and should relate properly with other parts of the model, be susceptible of further modifications and be able to receive new information. These and other related issues have been encountered and developed during the construction of several models at our Laboratory at the ETS Architecture of Barcelona. Our paper explains the main decisions we had to take during the course of these works with special emphasis on those aspects related with the organization of different kind of data in a unified whole that had to be sent to other professionals and had to be, for that reason, organized in a clear and comprehensible way for its further development.

title	ArDOT: A tool to optimise environmental design of buildings
source	Building Simulation 2003 (Eighth IBPSA Conference). Eindhoven, Netherlands
summary	Environmental design of buildings involves ‘finding the optimum’ solution satisfying predefined objective(s) (e.g., reduction in operating/capital cost, maximisation of daylighting etc.). A number of computer based simulation models exist to assist professionals in finding this optimum through building performance assessment. Contemporary practices involving building simulation require enormous effort to prepare input, extract output, and visualize data, which restricts designers from realizing the full potentials offered. In most cases, rules of thumb are applied and experienced guesses are made; simulation software is used only to validate the assumptions, which do not necessarily lead to the intended optimum. Moreover, these tools have been developed as simulation engines, which is inadequate to visualize the compounded and interdependent effect of a large number of design variables. The authors believe that to realize the potential offered by building simulation software, a new breed of DBSs (Decision Based Systems) is needed coupling existing simulation engines with formal optimisation methods through neutral data standards (BPM – building product models) for seamless integration. This paper first elaborates on the previous attempts at solving integration issues related to the design process and simulation; also attempts at finding the limitations. Secondly, formulation of design problems as optimisation has been discussed with reference to the different stages of design. Thirdly, for effective integration of activities among stakeholders and processes, the use of client/ server oriented building product model has been proposed to overcome the limitations of file-based prototypes. Analysis and discussions based on the above aspects form as justification for ArDOT, an Architectural Design Optimisation Tool under development at IRUSE, National University of Ireland, Cork. Combining all three aspects into one makes ArDOT unique, which is essentially an enhanced decision making tool for the design of energy efficient buildings.

title	Integrating building energy simulation in the design process
source	IBPSA News, Vol. 13, No. 1, pp. 21-26.
summary	To significantly increase building energy performance, the use of building simulation software at the earliest has been emphasized. Inherent complexity in data representation, I/O (Input and Output) and Visualization of available software requires specialist knowledge to leverage the potentials offered. Early stages of design are characterized by unstructured and incomplete data which is insufficient as inputs to software based on detailed representations of the systems in the building. Existing simulation software, developed in research organizations are targeted to be used by building services engineers at detailed stages and does not suit the purposes of design community. This article attempts at identifying the reasons behind unpopularity of simulation software in the early stages of design and also argues that a new breed of decision support systems is needed for energy efficient building design.

title	DATA MODELING OF BUILDINGS WITH BMXML
source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 533-540
doi	https://doi.org/10.52842/conf.ecaade.2003.533
summary	XML (extensible markup language) is emerging as a significant tool not only to model data but also to facilitate the seamless sharing of data between multiple domains. Therefore it can be quite powerful in modeling building data that must often be shared between large numbers of professionals. The focus of this study is how to use this paradigm in structuring spatial and component based building data with the intention to use it in the analysis and simulation of the performance of buildings. The framework developed by the authors consists of three components. An XML structure (bmXML) for storing building data, a VBA-AutoCAD-Application for generating the XML files (bmGenerator) and a JAVA-Application which reads the bmXML data and prepares the information for simulation purposes. This paper primarily focuses on theVBA-AutoCADApplication.

title	Decision-making through performance simulation and code compliance from the early, schematic phases of building design

doi	https://doi.org/10.52842/conf.ecaade.2003.103
summary	This paper is about the merging of two software applications that allows building decision makers to consider code compliance and to use performance simulation tools from the early, schematic phases of building design. By making the capabilities of a code compliance tool available at the early schematic phases of building design, the hope and expectation is that users will use this software to address the mandatory code compliance issues and thus have an opportunity to address other performance issues as well.

summary	Generative design methods are capable of generating concepts and stimulating solutions based on robust and rigorous models of design conditions, design languages and design performance. The computer now becomes a design generator in addition to its more conventional role as draftsperson, visualizor, data checker and performance analyst. Motivated by the challenge to enable designers to easily develop meaningful input models of design intent to make best use of a structural generative method, this paper describes an initial combination of a generative design tool, eifForm, and an associative modeling system, Custom Objects, through the use of XML models. The current combined use is illustrated through an example involving generation of a set of 20 interrelated roof trusses with seven unique spans initiated by a parametric model of a saddle shaped stadium roof in Custom Objects. The paper concludes with a discussion of the synergies between associative modeling and generative systems and identifies future extensions aimed to exploit these synergies towards integrated performance-based generative design tools.

title	Performing Cyberspace: Dance, Technology and Virtual Architecture
source	International Journal of Architectural Computing vol. 1 - no. 3
summary	This project investigates the design, construction and experimentation in digital environments. The work intends to contribute to the evolution of the virtual universe by studying what can be particular architectural expressions of cyberspace. Specifically the project explores the potential architectural manifestations of existential situations in cyberspace. The design goal is to artistically express, through virtual environments, the invisible part of ourselves, our thoughts and emotions. This work critically engages the cyberPRINT, a ongoing creative-research project of Prof. Bermudez and the C.R.O.M.D.I team at the University of Utah in the U.S.A. [1] This project uses the cyberPRINT concept and technology of obtaining physiological data and translating them into digital spaces. However, it proposes a new "world" for the cyberPRINT. The final product consists in a performance where a dancer sends his biological signals to the computer to generate and transform digital environments, and also represents through his movements, the desired existential situation.

summary	The paper proposes a new methodology how computational lighting and energy performance simulations and web based visualization tools can be employed to support energy integrated architectural design. By studying the current limitations of integrating simulation tools in the design process, the hypotheses of a web-based design guide attempts to establish computational simulation and visualization tools as a value adding part of the design process as well as contribute to the architect's understanding and concerns of energy relationships in buildings. The developed design guide attempts to address the identified limitations by making the actual simulations transparent to the designer physically and figuratively, the latter involving the studying of how to present data as useful information to the designer in post-processing techniques with special focus webbased visualizations.

title	Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 477-492.
summary	Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user‚Äôs interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

summary	We present as an example a story entitled "Invisible Cities" by Italo Calvino in which the author describes an imaginary city. Appealing to mathematical concepts, students seek to design a type of city or architectural space, arising from each student's interpretation of the text. Here, Literature, Design and Mathematics form a framework in which each discipline justifies the presence of the others. In our private case the need of an evolution of the language is presented besides by means of the use of the Digital Graphic.

title	Interactive Mapping between Knowledge Level and Symbol Level with Geometry. A KL-Model for Design Space Exploration

summary	Design space exploration is long-standing motivating ideas in computer-aided design. It realises this vision through a model of design states for making and moving amongst states and an organisation of states into a structure called a design space. Using a design space structuring mechanism based on a subsumption relation, this paper sketches a theory called Geometric Typed Feature Structures (GTFS) to preserve the formal properties of the design space movement algorithms for geometry. It also provides the theory for incorporation of user-guided exploration in the design space. Consequently, the clear division between knowledge level and symbol level, such that functional decomposition •• formal symbol level and design •• model symbol level, disappears. We can therefore use the same subsumption relation to structure the design space exploration interactively. Such interactive mapping between knowledge level and symbol level provides the fine-grained opportunities for user intervention in formal design space movement algorithms. In this paper, we summarize this approach with an example of GTFS subsumption process.

summary	This research explores Metadesign(Giaccardi, 2003)as an innovative framework on the design of urban lighting systems. We hypothesize that a system based on this mode of design can bring breakthroughs that could cope with ill-defined problems in urban lighting design. Therefore, the aim is to propose alighting system in support of participation through interaction at use time. In this sense, by comprehending lighting infrastructures as sociotechnical environments, we believe Metadesign could cope with emergent needs arising in the context of personally meaningful activities andcould empower users to engage actively in their systems development and evolution.
