title	Spatial Diagnosis as a Means to Design Mediated Spaces

summary	This paper addresses the concept of spatial diagnosis as a methodology for architects to analyze and evaluate the quality of existing spaces periodically and improve them with the use of digital media. Initially the methodology researches the physical characteristics of the examined space, which are investigated both historically and empirically, as well as people’s mental imagery of it, which is examined through cognitive mapping techniques. The research findings are used as a mapping device for the application of the digital media ‘treatment.’ Selected intelligent systems form a digital, immaterial layer upon the existing spatial elements increasing the quality of space and consequently improving people’s experience in it. The goal of this project, which focuses solely on public spaces for the extent of this research, is twofold. On a design level, it proposes a way to increase the quality of space as well as its potential to communicate with people through a synergic, adaptive approach. On a research level, it seeks to bring together three diverse but not distant disciplines, those of architecture, cognitive psychology and information technology.

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	Grammar Representations to Facilitate Style Innovation - An Example From Mobile Phone Design
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 320-323

summary	Previous research in generative design has suggested that shape grammar transformations could be used for developing new design styles by the systematic modification of grammars that encode existing styles. Our research explores how such grammar transformations can be facilitated to be responsive to changes in design style requirements. For this it is important to consider the structure and organization of rules, as well as the description of the styles of designs generated by a grammar. Using an example of mobile phone design, we outline the development of a flexible grammar structure that is conducive to transformations. The grammar is augmented with a style description scheme based on the concept of semantic differential to map the style characteristics of grammar components. These measures could be significant for driving purposeful grammar transformations for style adaptation and innovation.

title	Performance House: A CADCAM Modular House System
source	Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 104-121

summary	Millions of persons around the globe live in low quality indigenous, or Manufactured Housing (MH) systems that often result in low “performance” undesirable living environments and, at times, life threatening habitation. Our research has explored mass production principles in product design and architecture, currently at the single family housing scale, with a focus on the recent devastation along the US Gulf Coast as a result of hurricane impact, most notably hurricane Katrina.“Modern architecture” theoreticians have conceived, written, prototyped and even launched business ventures in an attempt to bring their manufactured housing “ideas” to fruition. However, architects have generally had little “long-term” impact in the area of manufactured housing strategies and the current manufactured housing industry remains archaic and problematic. This paper includes our research of other architects attempts to leverage technology in the manufactured housing industry; additionally, we analyzed current problems in the US mass housing industry. We then derived a set of “design criterion” as a means of anchoring our design inquiry for a proposed factory-built modular house system.Our research encompasses both process and product innovation; this paper reflects on our use of technology to leverage an Industrial Design (ID) process that is inclusive of many “design” partners and team members. We are using both virtual and physical output representation and physical prototyping for a factory-built house system; our Research and Development (R&D) is on-going with our collaborating design-manufacture engineering partners from the automotive, furniture and aerospace research labs here at Mississippi State University. Our goal is to use “industrial design” principles to produce mass housing components that provide durable-sustainable housing.

title	A Grammar for the Patio Houses of the Medina of Marrakech - Towards a Tool for Housing Design in Islamic Contexts
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 860-866
doi	https://doi.org/10.52842/conf.ecaade.2006.860
summary	The goal of the research described in this paper is to develop a computational model of the Medina of Marrakech in Morocco. The ultimate goal is to develop a system that could capture some of the characteristics of traditional Muslim cities fabric and use it in contemporary urban planning. Previous papers have proposed the use of three grammars to encode the spatial complexity of the Medina: the urban grammar, the negotiation grammar, and the housing grammar, and addressed the development of the urban grammar. This paper proposes a grammar to describe the formal structure of the houses, the first step in the developments of the remaining two grammars. It describes the set of rules and then illustrates its application in the generation of an existing house. The basic formal structure consists of three concentric rectangular rings with the patio in the middle. The location of the entrance and the staircase are fundamental for the definition of the basic layout.

summary	Augmented Reality (AR) technologies are often perceived as the most impactful method to enhance the communication between the designer and the client during the iterative design process. However, the significance of designing the User Interface (UI) and the User Experience (UX) are often underestimated. To intercede, this research aims to employ new and existing techniques to develop UI's, and comparatively assess "the accuracy and completeness with which specified users can achieve specified goals in particular environments" (Stone, 2005) - a notion this research delineates as 'effectiveness'. Prompted by the work of key scholars, the developed UI's were assessed through the lens of existing UI evaluation techniques, including: Usability Heuristics (Nielsen, 1994) and Visual and Cognitive Heuristics (Zuk and Carpendale, 2006). In partnership with PTW Architects, characteristics such as the rapidity and complexity of interactions, in conjunction with the interface's simplicity and intuitiveness, were extracted from 15 trials underwent by architectural practitioners. The outcomes of this research highlights strategies for the effective development of user interface design for mobile augmented reality applications.

summary	The research consists of the set up of a game simulating a e Collaborative Working Environment – CWE – in Architectural Design. The use of a game is particularly useful as it makes it possible to simplify the complex terms of the problem and, through the game itself, makes it easier to study knowledge engineering tools, communication protocols and the areas of an ICT implementation of a general model of collaborative design. In the following several characteristics of the game are given (also with reference to other games) such as; participating actors (Wix 1997), the “pieces” (construction components) used, the modular space employed, the PDWs/SDW dialectics, the screenshot of the interface prototype, the score.

title	Experimenting with 3D Digitization of Architectural Physical Models using Laser Scanning Technology
source	International Journal of Architectural Computing vol. 4 - no. 2, 67-80
summary	This paper assesses the use of 3D Digitization techniques by carrying out laser scanning of typical physical models produced by architecture students. The aim was to examine the product of laser scanning with respect to scanning and 3D modeling processes, and the effects of variables such as characteristics of the models, materials used, and design complexity. In order to assess the similarities and accuracies achieved by the scanning and 3D modeling processes, the research investigated human perception of differences between analogue and digital models. This enabled an assessment of the degree to which digital models were accurate representations of the real ones, and whether laser scanning can successfully be used as a medium to recreate and represent complex architectural physical models. The study presents a potential direction for digital translation in architectural education.

title	A Framework of Haptic Design Parameters for Architects: Sensory Paradox Between Content and Representation
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. 685-700.
summary	Architects‚Äîlike other designers‚Äîtend to think, know and work in a visual way. In design research, this way of knowing and working is highly valued as paramount to design expertise (Cross 1982, 2006). In case of architecture, however, it is not only a particular strength, but may as well be regarded as a serious weakness. The absence of non-visual features in traditional architectural spatial representations indicates how these are disregarded as important elements in conceiving space (Dischinger 2006). This bias towards vision, and the suppression of other senses‚Äîin the way architecture is conceived, taught and critiqued‚Äîresults in a disappearance of sensory qualities (Pallasmaa 2005). Nevertheless, if architects design with more attention to non visual senses, they are able to contribute to more inclusive environments. Indeed if an environment offers a range of sensory triggers, people with different sensory capacities are able to navigate and enjoy it. Rather than implementing as many sensory triggers as possible, the intention is to make buildings and spaces accessible and enjoyable for more people, in line with the objective of inclusive design (Clarkson et al. 2007), also called Design for All or Universal Design (Ostroff 2001). Within this overall objective, the aim of our study is to develop haptic design parameters that support architects during design in paying more attention to the role of haptics, i.e. the sense of touch, in the built environment by informing them about the haptic implications of their design decisions. In the context of our study, haptic design parameters are defined as variables that can be decided upon by designers throughout the design process, and the value of which determines the haptic characteristics of the resulting design. These characteristics are based on the expertise of people who are congenitally blind, as they are more attentive to non visual information, and of professional caregivers working with them. The parameters do not intend to be prescriptive, nor to impose a particular method. Instead they seek to facilitate a more inclusive design attitude by informing designers and helping them to think differently. As the insights from the empirical studies with people born blind and caregivers have been reported elsewhere (Authors 2010), this paper starts by outlining the haptic design parameters resulting from them. Following the classification of haptics into active, dynamic and passive touch, the built environment unfolds into surfaces that can act as ‚Äúmovement‚Äù, ‚Äúguiding‚Äù and/or ‚Äúrest‚Äù plane. Furthermore design techniques are suggested to check the haptic qualities during the design process. Subsequently, the paper reports on a focus group interview/workshop with professional architects to assess the usability of the haptic design parameters for design practice. The architects were then asked to try out the parameters in the context of a concrete design project. The reactions suggest that the participating architects immediately picked up the underlying idea of the parameters, and recognized their relevance in relation to the design project at stake, but that their representation confronts us with a sensory paradox: although the parameters question the impact of the visual in architectural design, they are meant to be used by designers, who are used to think, know and work in a visual way.

title	Developing a Spatial Context-Aware Building Model and System to Construct a Virtual Place
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Progress in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN-10: 90-386-1756-9, ISBN-13: 978-90-386-1756-5, p. 343-358
summary	The current notion of space seems to be inappropriate to deal with contemporary and future CAAD applications because it lacks of user and social values. Instead of using a general term called 'space', our approach is to consider the common unit in architectural design process as a place composed of space, user and activity information. Our research focuses on developing a novel intelligent building data model carrying the essence of place. Through our research, the needs of using virtual architectural models among various architectural applications are investigated at first step. Second, key characteristics of spatial information are summarized and systematically classified. The third step is to construct a semantically-rich building data model based on structured floor plan and the semantic location modeling. Then intermediate functions are created providing an interface between the model and future applications. Finally, a prototype system, PlaceMaker, is developed to demonstrate how to apply our building data model to construct virtual architectural models embodying the essences of place.

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	The research and development of smart houses are emergent because of the information and communication technological development and the search for better living quality from occupants. This paper therefore explores how smart technologies are applied into smart houses within the living context. Through a pilot study of cases and technological innovations to address the new living context by technology-interface-design strategies, a development framework of smart house is formed by three major elements, i.e. smart materials, technologies, and design. In order to actualize house senses, the prototype for smart houses is evolved. When space and wireless smart components are integrated, the living environment becomes more flexible and adaptable to accommodate or support activities digitally, and users can interact with space via context aware computing for acquiring and assimilating information in order to enhance their living experience.

title	CNC Timber Framing – Innovative Applications of Digital Wood Fabrication Technology
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 304-307
summary	The discourse on depleting natural resources and compromised environments have led to extended research on sustainable designs methods, building practices and materials. Beyond the actual performance of building products and components, research on sustainable building increasingly focuses on the long-term effects of the production, application and life cycle of building materials on the natural environment, human inhabitation and quality of life. Computer aided manufacturing technologies play a significant role not only in the transformation of design and building methods, but also in an extended discourse on cultural development. Globally available technologies connect the design and building process to a broad range of long-term ecological factors by creating a correlation between "the emergent political, economical and social processes and … architectural techniques, geometries and organization." Through this interrelationship to economy and culture, technology and its applications are also directly related to notions of place and territory as well as to fundamental ideas of ecology. The collaborative research and design study for an outdoor theater roof structure at the University of British Columbia Malcolm Knapp Research Forest at Maple Ridge, B.C., Canada, focuses on the use of digital media in prefabrication and material optimization. By utilizing small square section timber and minimizing the use of alienating connectors the research on the wood roof structure illustrates the potential of a design culture that seeks innovation in a broader understanding of ecology routed in regional culture, environmental conditions, economy and tradition. Labor intensive manufacturing techniques are redefined aided by computer controlled machines and virtual modeling of complex geometries is translated into simple operations. The result is a more sensible and accurate response to the place’s demands. In order to generate innovative design interventions that make a constructive long-term contribution to the preservation, maintenance and evolution of the environment, design needs to be based on a comprehensive understanding of its context and the distinctive qualities of the materials used. Following the example of the outdoor roof structure, this paper aims to define innovative design as work that resonates at the intersection of the fields of technology, material science, manufacturing processes, techniques of assembly and context that constitute the expanded context or complex ecology that projects need to engage. It is in design research studies like for the outdoor theater roof structure with focus on CNC wood fabrication technologies that the common design and building discourse is put to question, boundaries are explored and expanded and the collective understanding is improved towards ecological design.

title	Perception and Cognition in Real and Virtual Computer Generated Architectural Space - An Experimental Approach

doi	https://doi.org/10.52842/conf.ecaade.2006.724
summary	This paper investigates the difference of spatial perception and cognition between virtual and real architectural environments. Specifically, three different aspects have been studied, concerning the live perception and cognition of a complex actual building, the perception and cognition of a high quality rendered virtual space, as well as the perception and cognition of a non-photorealistic virtual environment. To study the differences between these three types a series of experiments were prepared, in which students of architecture participated and statistical results were drawn. Earlier studies have investigated the desirability of key simulation attributes for architectural design visualization, but extensive research on what contributes to a better spatial comprehension is still missing. This experiment is part of a series of experiments mainly focused on the perception and cognition in virtual spaces. The results of these experiments were correlated with each other, each one leading to new ideas of experimentation. Preliminary results confirm earlier findings from previous similar experiments. It was found that there was a statistically significant tendency of the students towards larger scatter in more luminous virtual space as well as a tendency to visit the lit part of virtual space. Visitors of the photorealistic spaces also seem to have better knowledge of the depth of space in comparison to those navigating in the non photorealistic space.

title	Simulation of architectural lighting in a virtual environment - A case study on real and fake High Dynamic Range Images (HDRI)
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 566-572

summary	The early findings of this research were presented in eCAADe 2005 International Conference, Lisbon primarily to highlight the concept of High Dynamic Range Images (HDRI) when representing architectural spaces in the form of still images. An experiment had been carried out to compare the results between HDRI rendering and ‘conventional’ lighting simulation algorithms namely ray tracing and radiosity. The results were based on static and using the same exposure factors, when capturing HDRI. This project, funded by Intensification Research Priority Area (IRPA) grant continues to present and report HDRI results in a simulation environment. In this paper, we first briefly explain on the concept of real and fake HDRI. Then a comparison experiment is conducted to compare these two methods and discuss the impact and effectiveness of the illumination computation in architectural simulation environment. In order to carry out the experiment, a few models of the architectural scenes were developed. These models were then textured with real photos and manipulated with ‘shaders’, and further rendered using fake and real HDRI techniques. As for the fake HDRI, two methods were developed. The first was using an image as the ambient map and different exposures were created by increasing the value of Hue, V of HSV and saturation. The second involved a series of digital photos with the selection of the brightest and darkest area using Adobe Photoshop to establish the scale of luminosity. A few camera movements were triggered and position for ‘real-time’ rendering simulation. The result of the experiment has shown a significant improvement on the rendering time and quality of the rendering. Finally this paper suggests the selection criteria for choosing real and fake HDRI, and how each technique can be best utilized for architectural representations in a simulation environment.

summary	Planning is a decision-making process which is about 'the future'. In each scale of planning process, spatial rules of the social life are formed. In this process, firstly series of spatial analyses should be practised. Throughout the world, spatial planning strategies which focus on the sustainable development adapt an ecological approach and both the regional and urban planning processes are based upon ecological bases. Under the guidance of this notion, also in Turkey, spatial planning strategies should be urgently reviewed and any level of planning process should be directed to ecological bases. Furthermore, in all these steps, natural resources and ecological characteristics should be taken into consideration. In the city of Bartin, where Bartin River flows through, a case study has been carried out regarding the above mentioned planning strategies. The case study has three stages. These stages also frame the data, analysis and evaluation stages. In the case study, a combination of McHarg's ecological evaluation method and Kiemstedt's usage value analysis in planning has been employed. With the help of ecological analyses, in the rural areas that have not been settled yet, the potential of the natural resources has been examined for the new residential areas. As a result, in the city of Bartin, the potential residential areas have been defined on the unsettled regions. What is more, concerning the subject, a map has been formed on the scale of 1/25 000. As a result of the case study, it has been concluded that in Bartin city because of the physical planning which ignores the potential of the natural resources, some of the existing residential areas have been chosen improperly.

summary	This research compares the working process at a construction site with the shop drawings made by a plumbing inspector for installed pipes. This study compared the 2D plumbing shop drawings with the 3D point cloud of the toilet in a campus building. A long-range 3D scanner was used to retrieve the point cloud records of pipes to build a visualization management system. The visual comparison was used to locate pipes at the construction site. We found the differences could be identified easily between the point cloud and shop drawings. The presence of point clouds created a new method to inspect plumbing locations, as a way to verify construction quality.

title	Mapping the City in Movement: The Car as an A/V Apparatus
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 397-400
summary	“…our experience of the city, and hence our response to architecture, is almost exclusively conducted through the medium of the automobile: the car defines our space whether we are driving, being driven or avoiding being driven over. The car has been an integral part of metropolitan life for so long that it has become part of the urban fabric.” Jonathan Bell, Carchitecture. This DVD presents a series of audio/video mappings of the city in movement - an organizational condition which is derived from our car culture, a culture in movement. In these studies the digital audio/video camera, a device which allows us to explicitly record movement and change in time, is used as an investigative tool and as an extension of our bodies in order to observe, capture and measure otherwise imperceptible moments of our moving and fast paced experience of place. The projects are from a seminar/studio entitled A/V Mappings and Notations. This research looks at the merging of moving image and more conventional drawing to create maps which read physical and ephemeral conditions of place in an experiential and analytical manner. The importance of The Car as an A/V Apparatus studies is that they allow us to uncover characteristics of place that are particular to the infrastructure of our car cities and most importantly to the experience of inhabiting the transitory spaces of these cities in movement. The projects which will be presented extend the human body into the city via the car as an audio/video apparatus, an instrument for reading and measuring the city in movement. The documents are choreographed as sections through the city in which the section cut (the line drawn) is the trajectory of driving/drawing. In the making of these full-scale life size drawings, cameras are mounted to the car prior to driving. The location(s) of camera(s) are determined by the specifics of each investigation. What is choreographed is the set up of the car as an audio/video apparatus and of the trajectory of driving. The apparatus itself, the body/car/camera, in its trajectory captures, studies, measures, draws/drives. This as an extension of the human body allows us to detach ourselves from the dominance of our vision and to more objectively discover aspects of place as related to our movement and corporeal experience and otherwise hidden from our perception. In addition and more importantly as body/car/camera, the apparatus captures the city at the scale of driving (corpor/car) a scale which expands our body into the scale of a larger space of great distances, movements, speeds, and durations. The discoveries that these mappings reveal inform us of the potential for more specifically intervening in these cities with proposals which engage these two drastically different yet intricately connected scales.

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.

summary	This paper illustrates the methodology, technological solutions and interaction metaphors chosen for the development of a 3D immersive Virtual exhibition that aims at enriching the visit of an important part of the historical cultural heritage of the city of Trento, in Italy. The goal of this work, supported by the local authority for Cultural Heritage, was to implement a user friendly virtual environment, which could show to the visitors the significance of the archeological findings of the ancient Roman town of Tridentum, despite the peculiarity of the site’s premises, located below a square among a theatre foundations. Outcomes of the research work are a high-quality and scientifically correct reconstruction of the Roman town in various historical eras, thanks to fruitful interaction with archeologists, and the development of an ad-hoc user-friendly immersive virtual environment implementing a customized interaction metaphor for the fruition of the virtual reconstruction. The developed interface allows users speaking different languages to share simultaneously the experience of virtual tours across time using a joystick. The whole environment has been developed to become a permanent virtual exhibition in the premises of the archeological site.
