title	Calibrated Sky Luminance Maps for Daylight Simulation
source	Vienna University of Technology; Building Science & Technology
summary	Building design and control applications can benefit from daylight simulation. Sky models help to model the sky conditions and predict the availability of daylight in indoor environments. Sky luminance is changing according to the weather, the season of the year and the time of the day, therefore it is difficult to create an accurate sky model. The simplified models that are currently used for computational simulation do not take into account these constant changes. It is important to test if there is the possibility of creating a sky model that approaches the characteristics of real sky and provides the architects with more precise daylight predictions. As past research has demonstrated, relatively low-cost sky luminance mapping via digital imaging can provide an alternative to highly sophisticated sky scanners and support the provision of information on sky luminance distribution patterns on a more pervasive basis. The aim of this research is first to explore the potential of deriving sky luminance distribution maps based on digital imaging and then to test their efficiency for the prediction of indoor daylight. A comparison is made between the predictions based on existing sky models (CIE Standard Skies and Perez All-weather sky) and the camera-based sky model. Thus, the effects of the selection of the sky model on indoor daylighting prediction are explored. A set of measurements were performed at the roof of the TU Vienna in order to obtain the necessary data. The horizontal illuminance levels due to 12 sky sectors were measured with the help of a sky monitoring device. A scale (1:5) model of an architectural space was used to measure the indoor illuminance values with the help of three sensors. At the same time, images of the sky were obtained with the help of a digital camera with a fish-eye converter. Luminance values were derived from the images and four calibration methods were used to generate accurate sky luminance distribution maps. These variously calibrated luminance values were then compared with the corresponding photometric measurements. Finally, the application of a digitally derived sky model based on the best calibration method was compared with the other two sky models toward the prediction of indoor illuminance levels using the case of the scale model. The results demonstrated that the camera-based sky model was more reliable than the other two sky models. It was concluded that digital imaging combined with parallel photometric calibration can provide a valuable means for a real-time generation of sky luminance maps. Detailed sky luminance models can be generated and their application can increase the predictive accuracy of the computational daylight prediction tools. Moreover, the reliability of daylight simulation can be increased toward supporting the design process and the operation of daylighting systems in buildings.

title	Shape Grammar of Geometric Islamic Ornaments
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 290-297

summary	Shape grammars are the algorithmic systems used to analyze existing designs or create new ones. In spite of using text or symbols to express abstract representations, shape grammars aid to create novel designs through computational effort with shapes and rules. Many probabilities of rule selections and applications of these rules may generate emergent design solutions or create new design objectives. This paper aims to present the characteristics, shape grammar rules and historical background of geometrical ornaments in Islamic culture and to point out the possibilities of mathematics of symmetry. The knowledge presented in this paper can be used to generate new depictions and to gain new application areas like typography, wallpaper, landscape, façade design, tiling, jewelry, and textile designs. Even, these types of shape grammar studies can be used to open a novel approach as in Jean Nouvel’s “Arab World Institute” in Paris. The role of shape grammar analysis of geometrical Islamic ornaments explained in this paper is to increase the efficiency of architectural design education by facilitating the formal understanding of historical patterns. Novel use of shape grammars in education can enrich the designer’s ability to generate original designs. In this paper variants of Islamic ornaments are created with a CAAD program. A selected geometrical bezeme (ornament) from Islamic ornamental design is generated by encoding with a computer programming language. According to the generated bezeme, interaction scenario is as follows: Computer has the main control over grammar application. Only, some of the rules can be selected by the user. Varieties of this ornament are generated randomly through their line weight, line colors, filling types and filling colors. The shape grammar rules outlined in this paper are simple, but the resulting figures can be very inspiring. Furthermore, the endless potential for future design innovations is unlimited.

title	Mass-Customization in the Design of 4,000 Bus Stops
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. 265-278.
summary	In Hawaii, ‚"TheBus‚" has been a main transportation system since 1971. Considering the high cost of living in Hawaii and the absence of a rail system, the use of ‚"TheBus‚" has been an instrumental vein of the city life in Honolulu with rhythmical pauses at about 4,000 bus stops in Honolulu. However, existing undifferentiated bus stops are developed from a cost effective mass production system so that they have been problematic for satisfying specific needs from various site conditions. In this research, an integrated computational method of mass-customization for designing 4,000 bus stops is introduced. According to various site conditions, the design of each bus stop is customized. Unlike the mass‚Äêproduced bus stops commonly seen in cities today, the proposed computational method in this paper produces bus stop design outcomes that fit into the physical characteristics of the location in which they are installed. Mass-customization allows for the creation and production of unique or similar buildings and building components, differentiated through digitally‚Äêcontrolled variation (Kolarevic, 2003). The employment of a computational mass‚Äêcustomization in architectural design extends the boundary of design solutions to the satisfaction of multi-objective requirements and unlimited freedom to search alternative solutions (Duarte, 2001; Caldas, 2006). The computational method developed in this paper consists of 1) definition of a prototype, 2) parametric variation, 3) manual deformation, and 4) simulation based deformation. The definition of a prototype is the development of a basic design to be transformed for satisfying various conditions given from a site. In this paper, the bus stop prototype is developed from the analysis of more than 300 bus stops and the categorization of the existing bus stops according to their physical conditions, contextual conditions, climatic conditions, and existing amenities. Based upon the outcome of the analysis, the design variables of a bus stop prototype are defined. Those design variables then guide the basic physical parameters for changing the physical configuration of the prototype according to a given site. From this, many possible design outcomes are generated as instances for further developments. The process of manual deformation is where the designer employs its intuition to develop the selected parametric variation. The designer is compelled to think about the possible implication derived from formal variation. This optional process allows every design decision to have a creative solution from an individual designer with an incidental quality in aesthetics, but substantiated functional quality. Finally the deformation of the selection is guided and controlled by the influence of sun direction/ exposure to the selection. The simulation based deformation starts with the movement of the sun as the trigger for generating the variations of the bus stop prototype. The implementation of the computational method was made within the combination of MEL (Maya Enbedded Language), autodesk MAYA and Ecotect environment.

title	An Analysis of the Applications of Rapid Prototyping in Architecture
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	Rapid prototyping (RP) techniques are widely used within the design/manufacturing industry and are well established in manufacturing industry. These digital techniques offer quick and accurate prototypes with relatively low cost when we require exact likeness to a particular scale and detail. 3D modeling of buildings on CAD-systems in the AEC sector is now becoming more popular and becoming widely used practice as the higher efficiency of working with computers is being recognized. However the building of scaled physical representations is still performed manually, which generally requires a high amount of time. Complex post-modernist building forms are more faithfully and easily represented in a solid visualization form, than they could be using traditional model making methods. Using RP within the engineering community has given the users the possibility to communicate and visualize designs with greater ease with the clients and capture any error within the CAD design at an early stage of the project or product lifecycle. In this paper, the application of RP in architecture is reviewed and the possibilities of modeling architectural models are explored. A methodology of developing rapid prototypes with 3D CAD models using methods of solid freeform manufacturing in particular Fused Deposition Modeling (FDM) is presented and compared against traditional model making methods. An economical analysis is presented and discussed using a case study and the potential of applying RP techniques to architectural models is discussed.

title	A Constraint-Based Building Bulk Design Support
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 278-282
summary	We introduce an architecture practice-oriented implementation strategy of constraint-based methods called BDS (Building Bulk Design Support) to supporting bulk analysis during the architectural programming phase. We examine the optmization problem of site coverage and building massing according to a set of standard planning and zoning regulations, and try a problem solving approach based on the paradigm of constraint satisfaction problems. The case study, which is focused on the paticipatory planning of very low-income dwellings within the Latin American context, serves as testbed for a prototypical application of the adopted methodology. The BDS constitutes a novel approach on computer-aided bulk analysis, regarding this particularly relevant context of application. In the case of participatively planned low-income housing projects, efficiency regarding time and cost of planning directly affects dwellers’ quality of life, whereas elementary programming tasks such as bulk analysis lack appropriate state-of-the-art technological support. Traditional architectural planning methods demand a large domain-specific knowledge base and skillful planners. A planning process, which is mainly driven by the formulation of planning-relevant constraints and sets of solution alternatives, suggests to avoid architects’ traditional procedure of: 1. Create an (yet not necessarily valid) instance of the eventual design solution by directly choosing specific values for its shape parameters. 2. Evaluate its validity by confronting the designed model to a set of applicable constraints, which have to be satisfied. Instead, the constraint-based design methodology poses a search procedure that operates in a space of pertinent constraint sets. A computer-aided interactive search procedure to find more valid design solution alternatives in less time and with less effort is particularly qualified to supply efficient support for participatory planning activities carried out between dwellers and planners. The set of solutions for a building-bulk design problem is constrained by both a large complex system of planning and zoning regulations and the geometry of the eventual design solution itself. Given a considerable amount of such regulations, a regular size geometric constraint satisfaction system proved to be capable of providing a highly efficient, interactive modeling and evaluation tool for the formulation in real time of valid solution alternatives for an ordinary building-bulk design problem. A BDS implementation will constitute one system module of a larger integrated system model called Esther. A BDS tool shall interact with other functional modules, like e.g. the FLS (Floor plan Layout Support), which also uses constraint-based design methods.

title	Movement in Architecture - An Analytical Approach Towards Organic Characteristics
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 714-719

summary	Nature is the fundamental and recurring inspiration of organic architecture. Living organisms, both in their outward forms and in their inner structures, offer endless ideas and concepts for design. Organic architecture works with metamorphosis (the process of growth and change), the notion of “design from within”. Why should architecture be lifeless and static? Here, Movement, a unique quality of living organism is used to contribute to architecture. We cannot make a new life but we can take the characteristics to make changes in our environment, seeking not to imitate nature’s appearance, but instead to imaginatively apply its profound principles. The focus of this paper is to examine and categorize the different kinds of movement that exist in nature, understanding how their purpose can be effectively used in architecture. The topic explores techniques of living organisms used for function and defense and discusses possible implementation in architecture. Movement has the potentiality to introduce flexibility, ecological efficiency and building defense through deformable, transportable, shape shifting and morphing forms.

title	Evolution or Revolution: is digital conceptual design the way forward for Architects?
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	This research investigates architectural conceptual design and discusses its recent historical, philosophical and theoretical development within the overall architectural design process and attempts to establish an objective definition more tuned to current thinking and advancement in technology. It also evaluates the various traditional and information technology (IT) tools available to the designer and establishes their relationship to the conceptual design process in order to identify if any of these tools, in particular the IT tools, have a role to play in the practice and the enhancement of the conceptual design process. A survey of Scottish practicing architects (small to medium size practices) was undertaken to validate the results of the investigation. The results seem to suggest that IT tools are not essential to the conceptual design process but that they are very well capable of enhancing the creativity and speed of some aspects of it. They also suggest the existence of an inherent resistance amongst Architects / designers to utilising these tools in conceptual design. It is, furthermore, identified that if practitioners were to encompass new working practices and acquire new skills, IT tools could also provide powerful new modes of communication with the client. A correlation between the size of the practice and the degree of exposure and experience of IT tools was also established. To test some of the above findings, a design studio experiment was undertaken where half of the students adopted digital tools, utilising SketchUp software and digital sketchpads, whilst the others adopted traditional tools for the conceptual design part of their projects. No attempt was made to gauge the quality of the actual designs produced. The results indicate that the SketchUp group rated their conceptual design experience higher in terms of efficiency, flexibility and communication. The control group, who had dominantly adopted traditional freehand sketching, were impressed by the outcome from the SketchUp group. All student who answered the questionnaire, both SketchUp and control groups, said they would consider adopting some form of 3D sketching in the future.

summary	New England’s seacoast is an active, working landscape. Here, with long history of whaling, sailing, and fishing, people have lived comfortably next to their economic infrastructure. Recent infrastructure projects, such as Deer Island Water Treatment Facility and the Big Dig, have embraced landscape as a way to facilitate modern “live / work” relationships.Wind turbines are part of the working landscape. So are ferries, commercial fishing, and cranberries. All clean, prosperous, and socially vibrant industry, we see the Cape Wind Project as a way to bring these landscape industries closer together, and to reestablish the vision of Cape Cod as a working landscape.The current wind proposal offers 100% efficiency with 0% consideration of the view. The turbines’ current configuration produces a view that is uneven and disorganized. Efficiency doesn’t have to be lost at the expense of aesthetics. By proposing a circle of turbines rather than a grid, an even perspective is provided for all of the cape and the islands (no strange bunches, as with the grid); the turbines are less dense, allowing one to see through them, and not just at them; service travel between turbines is shortened – 77 miles of travel for the grid versus 46 miles for the circle. By becoming larger, the effect of the circular array has become smaller.

summary	The spaces we live in are increasingly entwined in a complex weave of architecture and technology. With the evolution of intelligent devices that work in the background, design of place will eventually be a seamless integration of not just efficient but also experiential and virtual technologies. This signals a paradigm shift because “smart” architecture affords users a new interaction with architecture. In spite of such promises, we have seen interactive architecture ideas and “smart” environments only within laboratory walls or in the form of simplistic implementations. Perhaps the reason is simple. Rachael McCann asks if the integration of technology within the context of an increasingly information-driven modern era has abandoned the body in favor of the mind (McCann 2006). If we acknowledge that “smart” computing has the opportunity to transcend an efficient backbone to generator of experiences, perhaps we, as designers, must reconsider our position and strategy in this modern world. This paper is designed as a critical essay—one which evaluates interactive architecture and “smart” environments within the context of today’s socio-cultural climate. The paper hopes to open a discussion about the role of computing as architecture and the role of the architect in the design of such architecture.

title	Energy conscious automated design of building façades using genetic algorithms
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 898-902

summary	Various European Directives have been issued concerning the energy efficiency of the buildings. The target is the achievement of a near optimum energy efficient environment while at the same time satisfying occupant needs throughout the year within an integrated “holistic” or “whole building” framework. A variety of different antagonistic parameters should be balanced such as window size and glazing transmittance or daylighting and shading and in most cases this requires an examination of various scenarios. Thus the design of building envelopes should address a careful balance between internal requirements and loads, the materials and properties of the façade and the external environment. Nowadays, the available tools for façade design-in terms of building’s energy efficiency- are inappropriate for interactive or creative use. In this paper we examine the development of a genetic algorithm which is capable to optimise the opening areas, glazing properties and shading configurations –on the basis of minimum energy consumption- and then to design automatically simplistic alternative scenarios of the building façade.

title	Light and Form in Design – A Computational Approach
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 254-257
summary	Shape perception is strongly influenced by the reciprocal relation between light and form. Computational applications can increase the number of design alternatives taking into account possible variations in the relation between light and form. The aim of this study is to discuss a pedagogical experience carried out with 5th semester architectural students, based on a series of exercises prior to the term project. The exercises were concerned with the relation between light and form from an aesthetical point of view and should be understood as examples for the use of computers as tools to creatively accelerate the process of design and learning. The paper is divided in five parts. The first one describes the conceptual background for the exercises, a descriptive method for the identification of light effects in architectural objects based on ideas of shape emergence. The exercises’ methodology is explained in the second part, referring to the use of computational applications in 3-dimensional modeling, material and light simulation. The methodology includes different phases: –creation of bi-dimensional compositions according to symmetry operations; –creation of a minimal living space assigning functions to spaces originated from the former composition; –analysis of the impact of light on the form and spaces created; –alteration of form and materials creating new light effects considering the functions related to the spaces. The exercises alternate work in computational environment in two and three dimensions with the use of mockups, lamps and photography. In the third part the results –student’s design steps– are described. In the fourth part the results are analyzed and some conclusions are outlined in the fifth and last part. The use of emergent forms combined with computational tools has proved to be an effective way to achieve an accelerated understanding of the impact of light on forms as demonstrated by the evolution of the students work during the term and by their final results concerning the term project.

title	Generation of alternative designs in architectural problems using Shape Grammars defined with animation tools - A computer implementation of shape grammars using modelling and animation software
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 302-307
doi	https://doi.org/10.52842/conf.ecaade.2006.302
summary	We present a model of generation of alternative designs to selected architectural and spatial configurations of small complexity. Specifically we present a production pipeline of architectural / spatial configurations using the context of animation and time based design tools. Our model consists of time and space design constraints of boundaries / objects affecting a given architectural design, thus producing an alternative solution for every timeframe of the animation cycle. The alternative designs vary from the original according to their temporal and/or spatial distance from the original object on the animation time-line. The constraints placed upon the objects , used as actuators of Shape Grammars, are defined informally by the user/designer while their influence can vary according to time, speed, location, configuration of the object and/or the constraint itself. However the constraints further function as formal rules for the Shape Grammar creation so that our model tries to predict ahead of time the emergence of alternate designs. The employ of animation tools [shape driven curves, speed and time-line functions,parent child relationships] in the shape generation of our model empowers the user/designer to configure whole sets of shapes and designs interactively and without the need to define every solution independently. Simultaneously, a different, time-focused view of our model describes its use on designs that develop different configurations over time. Thus a duality of our model is established: either the animated schema may be a sum or family of various designs or the animated time-line represents a single design which changes over time. Finally the possibility of an automated analysis of every design is discussed, using Space Syntax diagrams so the designer can quickly evaluate the various spatial configurations produced by a single original.

title	Form follows function: Activity defines function, gesticulates space

doi	https://doi.org/10.52842/conf.ecaade.2006.298
summary	The foremost principle of this work is that the base level of architectonic form is spatial, and that the array of activities relative to the practice of habitation and their associational parameters to each other determine spatial boundaries, which might be uncovered, to define form. The array of activities, which define a particular ‘mode’ of habitation, will vary according to particular functions therefore defining building types. This might also be extended to the individual, in the case of an apartment or house in that the personal activities of an individual might be utilized to define custom form. Therefore defining a place of habitation, which reflects the individual qualities of that individual and responds to their personal mode of living, character and spatial requirements. Computationally I suppose space defined through an array of activities represented in 3D, and that the topology of activities defined geometrically through the application of an array of self-organizing activity maps for the morphology of space, to define form, relative to user/activity associations and context.

doi	https://doi.org/10.52842/conf.ecaade.2006.128
summary	This paper describes a procedure that feeds remotely a modelling system with geographical coordinates and the relative measurements taken in place in order to model dynamically new entities in real-time. The operation of this system is based on methodologies that are commonly used in telegeoprocessing – telegeomonitoring systems and its purpose is to simulate in real-time an existing environment using the captured measurements. The direct input of geographic data to the proposed system, which is adapted to a modelling environment (CAD or GIS), triggers the creation of new 3D entities in real-time (points, linear or area features), as it could be done with a traditional tablet digitizer. Simultaneously, the proposed system represents thematically the properties of the modelling entities (according to the measured values) over a 3D mesh. The aim of the suggested system is the remote registration of additional spatial information, their adequate treatment and adjustment via special developed interfaces, including their representation via developed software which is applied in the AutoCAD environment because of its programming development support and its use by a variety of engineers.

title	Gentrification Waves in the Inner-City of Milan - A multi agent / cellular automata model based on Smith's Rent Gap theory
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 187-201
summary	The aim of this paper is to investigate the gentrification process by applying an urban spatial model of gentrification, based on Smith's (1979; 1987; 1996) Rent Gap theory. The rich sociological literature on the topic mainly assumes gentrification to be a cultural phenomenon, namely the result of a demand pressure of the suburban middle and upper class, willing to return to the city (Ley, 1980; Lipton, 1977, May, 1996). Little attempt has been made to investigate and build a sound economic explanation on the causes of the process. The Rent Gap theory (RGT) of Neil Smith still represents an important contribution in this direction. At the heart of Smith's argument there is the assumption that gentrification takes place because capitals return to the inner city, creating opportunities for residential relocation and profit. This paper illustrates a dynamic model of Smith's theory through a multi-agent/ cellular automata system approach (Batty, 2005) developed on a Netlogo platform. A set of behavioural rules for each agent involved (homeowner, landlord, tenant and developer, and the passive 'dwelling' agent with their rent and level of decay) are formalised. The simulations show the surge of neighbouring degradation or renovation and population turn over, starting with different initial states of decay and estate rent values. Consistent with a Self Organized Criticality approach, the model shows that non linear interactions at local level may produce different configurations of the system at macro level. This paper represents a further development of a previous version of the model (Diappi, Bolchi, 2005). The model proposed here includes some more realistic factors inspired by the features of housing market dynamics in the city of Milan. It includes the shape of the potential rent according to city form and functions, the subdivision in areal submarkets according to the current rents, and their maintenance levels. The model has a more realistic visualisation of the city and its form, and is able to show the different dynamics of the emergent neighbourhoods in the last ten years in Milan.

title	Shape Morphing of Intersection Layouts Using Curb Side Oriented Driver Simulation
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 167-183
summary	In a traffic network, capacities of parts of the network restrict the amount of transport that can be handled by this network. The capacity of a given traffic network element is not fixed, but influenced by parameters such as number of lanes, maximum speed, weather, view horizon, and so on. These parameters also define the maximum capacity of complicated intersections. Special shapes of intersections, particularly in urban regions, may further increase or decrease their capacity. This paper investigates an evolutionary algorithm to automatically improve the geometrical layout of parts of an urban network according to externally specified criteria. The paper consists of two main parts. In the first part, a simulation model is described which is able to produce realistically behaving vehicles only by using information about the curb side locations of the roads. This avoids the need to use lane connectivity, signal plans, etc. - which are details that would change during a change of the intersection layout. In the second part of the paper, the simulation changes the road and intersection layouts based on the behaviour of the vehicles. Using a feedback loop allows one to optimize the capacity of the modelled road system while its spatial extents are minimized. As a case study, a special roundabout is examined: 'Central' in downtown Zurich, Switzerland. The particularity of this roundabout is that it partially behaves like a roundabout but also contains two uncontrolled intersections. Due to its central position in the city, the roundabout is very busy with both individual cars and public transport vehicles.

title	A 3D, interactive, multilayered, web-enabled model as a tool for multiple sets of end user groups: A case study and end user analysis
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 392-396
summary	This research undertakes a case study involving focus groups of potential end users, to identify how a successful digital tool could be created using new and emerging technologies, to accommodate the multiple needs of these end users. 2005 saw the completion of a research paper, which proposed that a single, 3 dimensional digital model of a city forming a core for many different information systems, is a better approach to the needs of the city than many individual models optimised for each information system. The case for the single 3D model was evaluated through the research, development, delivery and analysis of a prototype 3 Dimensional model of Wellington City, New Zealand, presenting different ‘views’ of information in Wellington: a rendered visualisation in an animated “walkthrough”; the impact of planning constraints on daylight; interactive “plots” of property values. The development and delivery of the prototype model was analysed in regards to how complex, costly and time consuming it may be to exploit one base model for several purposes; and also therefore how beneficial, affordable and potentially successful a single model may be. The prototype model was created to test the idea, and therefore provided conclusions based on a limited feasibility analysis - with four potential information layers modelled and two potential delivery methods tested. The prototype model and user analysis results were presented in a research report that suggested further research and development of a single model could be very beneficial: Positive feedback from potential end users and data providers, and examples of potential data mining opportunities forming the basis of the need for continued research. 2006 sees the research continue as an 18 month research project in conjunction with an industry partner, Terralink International, (http://www.terralink.co.nz/). Terralink International Limited provides GIS and mapping solutions which according to their web site: “enable better business management.” The company maintains a national resource of “imagery, cartography, and spatial databases” and provides consultancy services linking these to company databases through GIS systems. The research investigates the potential for 3 dimensional, interactive, multilayered models to enhance delivery of information to multiple end user groups. The research method uses functional prototypes in end-user focus group workshops. These workshops, consisting of a combination of presentations, hands on interactive examples, group discussions, and individual feedback surveys, aim to establish how a tool might best be developed to communicate to a wide range of end users. The means of delivery whether a stand alone tool or web-based is a key element of the user group workshop assessment process. Note: The submission of the prototype tool (via video or interactive media) would greatly increase the effectiveness of the research presentation. Ability to include such media would be greatly appreciated.

title	The Significant Role of an Electronic Gallery to the Education Experience and Learning Environment
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	Multimedia has brought new paradigms to education where users are able to use the technology to create compelling content that truly represents a new archetype in media experience. According to Burger (1995), the synergy of digital media is becoming a way of life where new paradigms for interactive audio-visual experiences of all communicative arts to date are mandatory. It potentially mixes technology and disciplines of architecture and art. Students can learn on their own pace and they can be tested in a non-linear way while interactivity allows the curious to easily explore related topics and concepts. Fundamental assumptions, theories and practices of conventional design paradigm are constantly being challenged by digital technology and this is the current scenario in architecture and art and design schools globally. Thus schools are enhancing the methods and improvising the technology of imparting knowledge to be in consistent with recent findings and knowledge. To be able to cater the use of digital media and information technology on architectural and art design education, four criteria are required, which are; the SPACE and place to accommodate the educational activities, the TOOLS that assist imparting of knowledge, the CONTENT of syllabus and information and the acceptance and culture of the receiving end users and HUMAN PERCEPTION. There is a need for the research of realization and activating the architectural space that has been equipped with multimedia tools and upgraded with recent technology to facilitate and support the community of learners and users. Spaces are now more interactive, multi functional, flexible and intelligent to suit the trend of computing in normal everyday life of the education sector, business and management, art and leisure, corporate and technological area. While the new concept of computing in education is still in the earlier phase, the conventional analogue paradigm still dominates the architectural design discourse which acts as a barrier to the development of digital designs and architectural education. A suitable approach is in need to bridge the gap between what theory has been explored and the practice of knowledge. A digital support environment with intelligent design and planning tools is envisioned to bridge the gap and to cater for the current scenario.
