title	Adaptive Kinetic Architecture: A Portal To Digital Prototyping
source	Smart Architecture: Integration of Digital and Building Technologies [Proceedings of the 2005 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 0-9772832-0-8] Savannah (Georgia) 13-16 October 2005, pp. 128-140

summary	This paper presents a definition for adaptive kinetic structures in architecture, generated from an examination of research in engineering and architecture. This characterization introduces the challenges presented both by modeling form and environment, and simulating their interaction. Adaptive kinetic structures react to a changing environment, as well as generate their own. These conditions make them appropriate subjects through which the design and implementation of tools for ‘digital prototyping’ may be explored. Digital prototyping serves performance and simulation-based design. In general terms, it is an interdisciplinary integrated approach for modeling, predicting, and analyzing the behavior of a system. It is at the core of virtual engineering. In the aerospace, automobile, and manufacturing industries, it is practiced extensively through discrete-event and continuous simulations, as well as simulation environments. This paper provides an overview of digital prototyping commercial software for engineering applications that can be transferred to architecture, and identifies some of the unresolved issues. It thereby extends the vision of the comprehensive building information modeling initiative.

title	Assessing the Use of Advanced Daylight Simulation Modelling Tools in Enhancing the Student Learning Experience
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 303-313
summary	In architecture schools, where the ‘studio culture’ lies at the heart of students’ learning, taught courses, particularly technology ones, are often seen as secondary or supplementary units. Successful delivery of such courses, where students can act effectively, be motivated and engaged, is a rather demanding task requiring careful planning and the use of various teaching styles. A recent challenge that faces architecture education today, and subsequently influences the way technology courses are being designed, is the growing trend in practice towards environmentally responsive design and the need for graduates with new skills in sustainable construction and urban ecology (HEFCE’s consultation document, 2005). This article presents the role of innovative simulation modelling tools in the enhancement of the student learning experience and professional development. Reference is made to a teaching practice that has recently been applied at Portsmouth School of Architecture in the United Kingdom and piloted at Deakin University in Australia. The work focuses on the structure and delivery of one of the two main technology units in the second year architecture programme that underwent two main phases of revision during the academic years 2009/10 and 2010/11. The article examines the inclusion of advanced daylight simulation modelling tools in the unit programme, and measures the effectiveness of enhancing its delivery as a key component of the curriculum on the student learning experience. A main objective of the work was to explain whether or not the introduction of a simulation modelling component, and the later improvement of its integration with the course programme and assessment, has contributed to a better learning experience and level of engagement. Student feedback and the grade distribution pattern over the last three academic years were collected and analyzed. The analysis of student feedback on the revised modelling component showed a positive influence on the learning experience and level of satisfaction and engagement. An improvement in student performance was also recorded over the last two academic years and following the implementation of new assessment design.

title	Towards a BIM-Based Energy Rating System
source	Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 285–294

summary	Governments in Australia are faced with policy implementation that mandates higher energy efficient housing (Foran, Lenzen & Dey 2005). To this effect, the National Construction Code (NCC) 2013 stipulates the minimum energy performance for residential buildings as 114MJ/m2 per annum or 6 stars on an energy rating scale. Compliance with this minimum is mandatory but there are several methods through which residential buildings can be rated to comply with the deemed to satisfy provisions outlined in the NCC. FirstRate5 is by far the most commonly used simulation software used in Victoria, Australia. Meanwhile, Building Information Modelling (BIM), using software such as ArchiCAD has gained a foothold in the industry. The energy simulation software within ArchiCAD, EcoDesigner, enables the reporting on the energy performance based on BIM elements that contain thermal information. This research is founded on a comparative study between FirstRate5 and EcoDesigner. Three building types were analysed and compared. The comparison finds significant differences between simulations, being, measured areas, thermal loads and potentially serious shortcomings within FirstRate5, that are discussed along with the future potential of a fully BIM-integrated model for energy rating certification in Victoria.

title	Creative Design Between Representation and Simulation
source	CAAD \| INNOVATION \| PRACTICE [6th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2012 / ISBN 978-99958-2-063-3], Manama (Kingdom of Bahrain), 21-23 February 2012, pp. 11-12
summary	Milestone figures of architecture all have their different views on what comes first, form or function. They also vary in their definitions of creativity. Apparently, creativity is very strongly related to ideas and how they can be generated. It is also correlated with the process of thinking and developing. Creative products, whether architectural or otherwise, and whether tangible or intangible, are originated from ‘good ideas’ (Elnokaly, Elseragy and Alsaadani, 2008). On one hand, not any idea, or any good idea, can be considered creative but, on the other hand, any creative result can be traced back to a good idea that initiated it in the beginning (Goldschmit and Tatsa, 2005). Creativity in literature, music and other forms of art is immeasurable and unbounded by constraints of physical reality. Musicians, painters and sculptors do not create within tight restrictions. They create what becomes their own mind’s intellectual property, and viewers or listeners are free to interpret these creations from whichever angle they choose. However, this is not the case with architects, whose creations and creative products are always bound with different physical constraints that may be related to the building location, social and cultural values related to the context, environmental performance and energy efficiency, and many more (Elnokaly, Elseragy and Alsaadani, 2008). Remarkably, over the last three decades computers have dominated in almost all areas of design, taking over the burden of repetitive tasks so that the designers and students can focus on the act of creation. Computer aided design has been used for a long time as a tool of drafting, however in this last decade this tool of representation is being replaced by simulation in different areas such as simulation of form, function and environment. Thus, the crafting of objects is moving towards the generation of forms and integrated systems through designer-authored computational processes. The emergence and adoption of computational technologies has significantly changed design and design education beyond the replacement of drawing boards with computers or pens and paper with computer-aided design (CAD) computer-aided engineering (CAE) applications. This paper highlights the influence of the evolving transformation from Computer Aided Design (CAD) to Computational Design (CD) and how this presents a profound shift in creative design thinking and education. Computational-based design and simulation represent new tools that encourage designers and artists to continue progression of novel modes of design thinking and creativity for the 21st century designers. Today computational design calls for new ideas that will transcend conventional boundaries and support creative insights through design and into design. However, it is still believed that in architecture education one should not replace the design process and creative thinking at early stages by software tools that shape both process and final product which may become a limitation for creative designs to adapt to the decisions and metaphors chosen by the simulation tool. This paper explores the development of Computer Aided Design (CAD) to Computational Design (CD) Tools and their impact on contemporary design education and creative design.

title	Real Time Visualizing Tools: Description of an experience where game engines and Internet browsers are used as means of exhibition at an archaeological site
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 2, pp. 689-694
summary	This paper presents the use of Virtual Reality (VR) environments as didactic means of exhibition. It approaches VR field by non traditional tools of visualization -as game engines- and describes the process and particular issues faced during its development. The examples shown in this document are part of an archaeological project under current development which faced budget solutions for equipment and its maintenance. The lack of experience outside the traditional VR field (SGI), lead the research team to try different game engines and VRML format in explore solutions to issues as performance, complexity, appearance, visualization, different needs of programming skills, file format compatibility, archiving and promotion applications. The experience delivered to replicate the process for other cultural projects can be useful also to architects and designers that are willing to experiment with VR as means of visualization during different stages of their projects.

title	Generative Design Systems for Housing

doi	https://doi.org/10.52842/conf.ecaade.2005.501
summary	The present paper describes an undergoing research that aims at developing a generative design computer implementation with an outside-in approach, OIDS. The system will allow developing and visualizing context-based housing development designs. This approach will include both natural characteristics of the site and the existing neighboring buildings. It is argued that certain common urban design practices are the result of a simplification due to difficulties in dealing with the irregularities of the natural environment, which often requires the use of time-consuming methods. The computer-based application will provide tools for dealing with such difficulties, allowing designers to describe their own design rules. In an initial phase of the project, a tool that can subdivide irregular land parcels into equally sized areas has been developed. In further stages, other environmental variables will be addressed, such as solar aspect and prevalent wind directions. Eventually, even the designs of interior layouts should result from exterior forces. The resulting generative system is expected to facilitate and encourage the use of a more organic approach to building siting and design, bringing about the important discussion about which should be the main forces in the generation of the built environment.

title	Parametric Surfaces And Architecture: Concepts, Design, and Production

summary	By incorporating parametric surfaces and spline entities into the shape modeling computer systems, new design and production graphic tools have been created in the conceptual and poetic field of architecture; thus allowing an intuitive approach to the fast production of complex shapes with a minimum amount of data and specific knowledge. The analogous production systems (constrained by the material resources and constructive procedures present in the local existing technologies) are challenged by design and virtual simulation systems, suggesting new relationships between the architectural features and their representation: the creation of a symbolic and dynamic information space where the representation affects the identity of what is being represented. Taking into account this current challenge mentioned above, we have decided to work in the mixture, without reciprocal exclusions or substitutions, proposing some work alternatives to approach the issue under discussion in the Architecture Workshop.

title	Architectural space between reality and virtuality: simulation or reality?
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 517-521
summary	This study was carried out under the Theory, Epistemology, and Philosophy principles, and is part of the PAAVI Project: The Architectural Design Process in Interactive Virtual Environments. The study presents part of the theory reference landmark that furnishes support in methodology and process approaches to the empirical research groundwork. The study also addresses the dimensions of architectural space and its representation in cyberspace. Comparisons are made between: static space/dynamic space – mathematical laws/architectural principles – interaction during the infographic process and formal manipulation of software – shape/form/function/space/void – distances/effects/rendering. The basic hypothesis is that the decisions made while solving architectural problems demand in-depth thought and ponderation. This is necessary in the light of the project theory, using the computer tools, electronic media, and concepts that structure different software. These software operations interfere in and interact with conception, appropriation, use and the esthetics of space and architectural form. [Full paper in Portuguese]

summary	This paper investigates the impact of Tablet PCs on the workflow in an undergraduate design studio. We examined how well the students adapted the Tablet PC into their day-to-day design work and evaluated the appropriateness of the Tablet PC as a common digital tool used in an architectural design studio. This research involved observation of student behavior during the semester and the conducting of a survey measuring various aspects of the students’ use of the computers. A more specific goal was to compare the effectiveness of the pen versus the mouse as input devices for a three-dimensional modeling task in terms of both task time and strategies. Our assumption was that a change in input mode would affect the strategies and the performance. The results of a within-subjects, repeated-measures experiment carried out to elicit differences in input devices are discussed.

summary	In this paper we describe our findings regarding the role of context in usability evaluation, particularly how the nature of the tasks can affect the users’ perception of the performance of a particular application. Our findings show a relationship between the variation in the nature of the tasks used for usability evaluation and the way in which subjects evaluate these applications afterwards using user -administered questionnaires. Our findings contradict the absolute benchmarking goal of some of these tools, and pose questions about the possibility of achieving that kind of benchmarks in software usability evaluation.

title	A Quantitative Method to Compare the Impact of Design Mediums on the Architectural Ideation Process.
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. 539-556.
summary	If we compare the architectural design process to a black box system, we can assume that we now know quite well both inputs and outputs of the system. Indeed, everything about the early project either feasibility studies, programming, context integration, site analysis (urban, rural or natural), as well as the integration of participants in a collaborative process can all be considered to initiate and sustain the architectural design and ideation process. Similarly, outputs from that process are also, and to some extent, well known and identifiable. We are referring here, among others, to the project representations or even to the concrete building construction and its post-evaluation. But what about the black box itself that produces the ideation. This is the question that attempts to answer the research. Currently, very few research works linger to identify how the human brain accomplishes those tasks; how to identify the cognitive functions that are playing this role; to what extent they operate and complement each other, and among other things, whether there possibly a chain of causality between these functions. Therefore, this study proposes to define a model that reflects the activity of the black box based on the cognitive activity of the human brain. From an extensive literature review, two cognitive functions have been identified and are investigated to account for some of the complex cognitive activity that occurs during a design process, namely the mental workload and mental imagery. These two variables are measured quantitatively in the context of real design task. Essentially, the mental load is measured using a Bakan's test and the mental imagery with eyes tracking. The statistical software G-Power was used to identify the necessary subject number to obtain for significant variance and correlation result analysis. Thus, in the context of an exploratory research, to ensure effective sample of 0.25 and a statistical power of 0.80, 32 participants are needed. All these participants are students from 3rd, 4th or 5th grade in architecture. They are also very familiar with the architectural design process and the design mediums used, i.e., analog model, freehand drawing and CAD software, SketchUp. In three experimental sessions, participants were asked to design three different projects, namely, a bus shelter, a recycling station and a public toilet. These projects were selected and defined for their complexity similarity, taking into account the available time of 22 minutes, using all three mediums of design, and this in a randomly manner to avoid the order effect. To analyze the two cognitive functions (mental load and mental imagery), two instruments are used. Mental imagery is measured using eye movement tracking with monitoring and quantitative analysis of scan paths and the resulting number and duration of participant eye fixations (Johansson et al, 2005). The mental workload is measured using the performance of a modality hearing secondary task inspired by Bakan'sworks (Bakan et al.; 1963). Each of these three experimental sessions, lasting 90 minutes, was composed of two phases: 1. After calibrating the glasses for eye movement, the subject had to exercise freely for 3 minutes while wearing the glasses and headphones (Bakan task) to get use to the wearing hardware. Then, after reading the guidelines and criteria for the design project (¬± 5 minutes), he had 22 minutes to execute the design task on a drawing table allowing an upright posture. Once the task is completed, the subject had to take the NASA TLX Test, on the assessment of mental load (¬± 5 minutes) and a written post-experimental questionnaire on his impressions of the experiment (¬± 10 minutes). 2. After a break of 5-10 minutes, the participant answered a psychometric test, which is different for each session. These tests (¬± 20 minutes) are administered in the same order to each participant. Thus, in the first experimental session, the subject had to take the psychometric test from Ekstrom et al. (1978), on spatial performance (Factor-Referenced Cognitive Tests Kit). During the second session, the cognitive style is evaluated using Oltman's test (1971). Finally, in the third and final session, participant creativity is evaluated using Delis-Kaplan test (D-KEFS), Delis et al. (2001). Thus, this study will present the first results of quantitative measures to establish and validate the proposed model. Furthermore, the paper will also discuss the relevance of the proposed approach, considering that currently teaching of ideation in ours schools of architecture in North America is essentially done in a holistic manner through the architectural project.

title	HYBRID MODELING: MANUAL AND DIGITAL MEDIA IN THE FIRST STEPS OF THE DESIGN PROCESS
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 819-827
doi	https://doi.org/10.52842/conf.ecaade.2005.819
summary	This paper proposes a new paradigm in computer-aided design: hybrid modeling. Considering, on one hand the traditional sketches and mock-ups, and digital techniques on the other, this paradigm fuses the two and proposes a new technique that uses the performance of the digital with the capacities of the analog without replacing or imitating one or the other. In the development of design computer solutions, it is important to know the user well. However, most researchers propose systems that do not consider how designers actually work. Furthermore, two principal elements must be considered in the design process: shape and space. These aspects need to be approached with convenient tools that are adapted to the designers. This new paradigm is presented through two new innovative techniques: the hybrid mock-up (for shape) and drafted virtual reality (for space). A review of the implications of this paradigm on the design process is presented. Not only are the techniques fast and easy to learn and execute, but the results demonstrate that the designers can express both their individuality and the idiosyncrasies of their personal representations; important elements that are difficult to achieve with conventional 3D modeling techniques, especially during the primary stages of the design process.

doi	https://doi.org/10.52842/conf.caadria.2005.475
summary	The technology of nanoblock-based circuits is enabling the creation of ultra-small sensors that can transmit their location and readings using radio frequencies. This technology has the potential to enhance the optimization of environmental performance criteria in spatial enclosures, using a wide range of actuators that function at different scales. The combination of such ultra-small sensors with actuators will enable the creation of spatial enclosures that are complex adaptive systems, which dynamically optimize the various environmental performance criteria for the enclosures. Defining a model for the optimization process in these systems presents significant challenges. This paper will set out a model for the use of ultra-small sensor systems in optimizing environmental performance criteria in spatial enclosures, especially acoustical performance criteria.

title	Design Using Evolutionary Optimisation and Associative Geometry
source	Learning from the Past a Foundation for the Future [Special publication of papers presented at the CAAD futures 2005 conference held at the Vienna University of Technology / ISBN 3-85437-276-0], Vienna (Austria) 20-22 June 2005, pp. 243-254
summary	This paper describes the usage of parametric design and evolutionary optimisation techniques in architect-engineer collaborations. It discusses the apparent challenges in setting up a trans-disciplinary working-platform that cuts across profession-specific boundaries and negotiates between the otherwise distinct work-methodologies through the use of intelligent CAAD applications. Two approaches to architectural form finding have been combined in this research. The first, parametric design, uses a proprietary package as a key element to the organisation and reorganisation of architectural design. By doing so, it is providing it with intrinsic flexibility allowing designers to go beyond form and accommodate performance data for versioning. The second, ESO (Evolutionary Structural Optimisation), is an engineering tool based on the use of finite element analysis (FEA) capable of optimising the formal geometry of an object to obtain minimum volume under even stress-distribution through an iterative design process. In undertaking this research it became apparent that different levels of resolution need to be addressed in the form-finding process in order to investigate the full potential of the interactive use of parametric design and evolutionary optimisation. The case studies reflect this diversity and demonstrate more successes, limitations and future challenges within the transdisciplinary, collaborative effort.

title	A Networked Sketching Environment for Supporting Collective Creativity

doi	https://doi.org/10.52842/conf.ecaade.2005.197
summary	In the early conceptual design, individual designers often make extensive use of sketches to explore design problems. Moreover, within the collaborative design sessions, designers communicate and discuss with each other by sharing their temporary sketches. These private design artifacts are used to externalize ideas and share them with other designers in order to facilitate the performance of design sessions. During such social interaction performance, some abstraction behaviors behind social activities like collective creativity are synchronized. However, the existent tele-communication tools proposed for separated design groups, slightly hold back the activities of collective creativity. It makes designers dedicated just in the table discussion, and negatively influenced on collective creativity sharing. Thus, some private design artifacts became isolated in tele-communicative environments. In order to respect this, we propose an approach that uses the notion of Digital Backchannel to realize the sub-channel communications. In this paper, we also present the implementation of a working prototype of groupware application. Finally, we discussed some points from our studies.

title	An Open Space with Scenery: ‘Greenscape Index’ for Performance Based Planning of High Density Urban Habitation
source	CAADRIA 2005 [Proceedings of the 10th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] New Delhi (India) 28-30 April 2005, vol. 1, pp. 328-334
doi	https://doi.org/10.52842/conf.caadria.2005.328
summary	This paper presents an improvement of the original openness ratio concept, which has been formulated as an integrated index for early-stage urban open space planning and design support. The ‘greenscape index’ is a rating system which quantitatively integrates human visual perception with the visible landscape resources to evaluate the visual quality of open space vision within high-density urban environment. This new index is expected to provide more comprehensive environmental performance consideration criteria for urban planning and design. The research team also discusses the potential of the introducing this index to assess both psychological preference and physical form of urban open spaces. The new concept also has shown its feasibility on integrating key environmental considerations in visual sensitivity, urban wind, urban noise and solar heat gain into simple massing study which is applicable in the preliminary planning stage.

summary	During the modelling, because of the sometimes complex architectural shape of halls, we were forced to introduce simplifications in order to carry out calculations and simulation operations on these halls, as the calculation software requires plane surfaces. This paper presents a developed tool adapted on a CAD modelling system (AutoCAD), which defines an “average limits” of the model simplification operation in order to control and diminish the falsification of calculation and simulation results on this model, such as the architectural acoustic simulation. The process of the elaboration and the adjustment of the simplified models of the Grand Theatre of Bordeaux (GTB) based on acoustical measurements and their calculation results are described in detail in a previous article (Kouzeleas and Semidor, 2001). The analysis process of the consequences of the hall model simplification on the acoustical simulation results and the applied simplification methods are described in a PhD thesis (Kouzeleas, 2002). This article is based on this analysis process in order to apply it on several simplified models of the Amphitheatre of the Architecture School of Bordeaux (Amphi- EAPB). The comparison in a CAD system (AutoCAD) of the acoustical calculation results and the areas after simplification of the simplified models of these two halls made with AutoCAD, via the developed tool adapted on the AutoCAD, permit to define a “limits average of a hall model simplification” before the falsification of these calculation results.

summary	This paper presents an immersive gesture-recognition-based system to visualize the indoor thermal environment using Computational Fluid Dynamics (CFD). To enable efficient visualization of CFD in actual space, an Augmented Reality system was integrated with a CFD simulation engine. To facilitate efficient data manipulation of the simulated postprocessed CFD data and to increase user control of the immersive environment, an intuitive method of Human-Computer Interaction (HCI) has been incorporated using gesture and speech recognition. While gesture recognition aids in transforming hand postures into command functions through forward kinematics and computation of hand segment positions and their joint angles, speech recognition allows better control of the data manipulation. This enabled real-time interactions between the users and simulated CFD results in actual space.

summary	Contemporaneus art constructs its own space: interactive, multiple, eidetic, heterogenous, discontinuous and subjective: essence, forms and idea of a heterotopic at the same time atopic space, that arises at the moment of the intelligible apprehension of the work. This work sets out to study the construction codes of that space from the spectator point of view, for whom the history is the sum of histories narrated by the space, the scenery, stage scene, choreography, dances, hairdos, accessories, make-up, clothes, illumination, music, sounds, songs, word, performance, gestures etc., for which sets out the analysis from the perceived, analyzed and interpreted images by the spectator. It will be exemplified from the Dogville film, of Lars Von Traer (2004), using the qualitative research method, where the speaker meaning is introduced: the creator intentionality of those spaces, but is inescapable who arises the “interpretation” from the observer.

summary	This paper describes a generative evolutionary design system that aims to fulfil two key requirements: customisability and scalability. Customisability is required in order to allow the design team to incorporate personalised and idiosyncratic rules and representations. Scalability is required in order to allow large complex designs to be generated and evolved without performance being adversely affected. In order to fulfil these requirements, a computational architecture has been developed that differs significantly from existing evolutionary systems. In order to verify the feasibility of the this architecture, the generative process capable of creating three-dimensional building models has been implemented and demonstrated.
