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	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	VIRTUAL CONTEXT - INVESTIGATING THE CHARACTERISTICS AND OPPORTUNITIES OF DIGITAL VISUALISATION MEDIA FOR SITUATED APPROACHES TO ARCHITECTURAL DESIGN IN AN URBAN ENVIRONMENT
source	Delft University Press
summary	This research initiative addresses the issue of Design in relation to Virtual Context. Central to this study are the innovative potentials and instrumental opportunities of computer based media techniques, capable of generating interactive models and changing perspectives for the benefit of urban and architectural design. The ambition was to not only make a contribution to the existing body of knowledge concerning digital technologies and their applications, but explore theoretical conditions which might help define and stimulate further study. From the outset, the focus was on furthering the opportunities for computer based representation media in creative design. On the basis of a series of explorative studies the subject of this research was targeted: the issue of Design in Context, or more specifically: Design(ing) in a Virtual Context. During the process there was a marked shift in the conception of the subject from – more or less immersive – VR technologies in the direction of approaches which might be expected to become readily available in practice and education and could be effective in actual design processes. This insight also brought about a shift in emphasis from realism per-se towards creating a sense of situatedness. The design representation system which was developed was intended to not just allow for one type of model view, but to afford an array of different views, from which the designer would be able to choose freely, depending on the phase and focus of design as well as personal preferences. A series of interface prototypes and support tools were developed especially and successively tested experimentally. For the intended final design driven experimental study, different virtual context models were considered. Eventually, an integral – purely fictitious – design ‘environment’ was constructed in the computer, so that the workings of the proposed system and its components would be tested systematically. A conscious choice was made for an in depth study, on a relatively modest scale, which would a certain amount of mutual involvement between designer and researcher, to confront the participants with the finer aspects of the proposed system in a relatively short time and to gather detailed data. A half dozen design professionals were invited to participate in a closely monitored experimental exercise. The results of this study therefore do not offer straightforward, indisputable facts, to be considered representative for the design community as a whole, but indicate that the working methods of the individual designers – when discovering aspects of the site, developing and presenting proposals and reflecting on the qualities of represented designs – tend to vary considerably. For this reason the interactive representation system proved to be of value. Participants could express different view preferences, with more or less realistic image modes being used in different phases of their design developments, with varying experiences of situatedness. Some of the design professionals participants were very appreciative of the system’s opportunities, others tended to be more ‘set in their ways’. The results of this experimental study indicate that there may particularly be opportunities for interface applications which are able to function interactively, offering individual designers – as well as others involved in evaluating design proposals – a variety of tools with which to approach specific design artefacts in their changing contexts. Virtual models can play not only an important role as a ‘reminder’ for the designer but also to other parties playing an active role in the design and implementation processes. Interactive environment models are not only promising as exploration tools for existing sites, but could be valuable to test the impact of a design on its location. This could be especially interesting if the site is difficult or impossible to visit or as yet a virtual construction. In addition such an approach might be beneficial for objective comparison and evaluation of design proposals in competitions and in education as well as in on-line collaborative design projects where the context is still in the process of being developed.

title	Filmic Development of Architectural Animations
source	International Journal of Architectural Computing vol. 3 - no. 3, 299-316
summary	This paper proposes a general method to make animated presentations of architectural designs, based on cinematographic techniques. Particularly, it reviews theoretical documenttion about filmmaking as well as several productions that exhibit remarkable locations. The proposed method first comprises of a planning stage, with the narrative and graphic formulation of the presentation. Next is an elaboration or adjustment stage for the digital modelling of the design, and finally, there is an animation production and editing stage. Likewise, the research sets up a computer implementation of some activities and characteristics, and experiments in the programming of camera movements for architectural animations. In general, this work suggests focusing on the communication of the qualitative features of the design, instead of the elaboration of the digital model, and on emphasizing the visual diversity, graphic style and narrative construction of the presentation.

title	Organisation of Pedestrian Movements: an Agent-Based Approach

summary	Cities are becoming more complex in this digital era due to technological changes. Thinking of cities without such technological changes is equivalent to an embryonic state in the morphology of city growth, that is, the growth seems less advanced. So it is appropriate to think of the non digital city digitally. Urban design is one state which establishes the perfect relationship between the street, people and building. The relationship of the people with the building and street is becoming one of the key factors in architecture. It has been observed that the design of a city has been influenced by the pedestrian movement. Many cities prior to the industrial era were largely determined by the social interactions based on walking. Thus the pedestrians play a key role in the formation of the city. They are a very important component in any representation of transport movements. They generally terminate or initiate a chain of linked activities, and if observed carefully, a single pedestrian movement is meant to include various sub journeys from one location to another. In order to organize pedestrians, we need to understand the pedestrian movement system. Though there is a lot of development of urban models in this aspect, it is still in a nascent state in comparison with the digital advancement. Thus much research work is carried out which can be applied to any given environmental setting, and as a result urban designers can respond to the changing socio-cultural technologies.

doi	https://doi.org/10.52842/conf.ecaade.2005.811
summary	There are two dominant approaches to architectural and urbanistic problem solving: program based approaches and paradigm based approaches. Beyond these two, this paper proposes the critical/formalist approach as a paradigm for architectural design while summarizing the epistemological foundations of it, and investigates the possible contribution of the computers to this approach. The primary aim is to set a starting point for a more comprehensive future research.

title	Integrating Digital and Building Technologies: Towards a New Architectural Composite
source	International Journal of Architectural Computing vol. 3 - no. 2, 181-190
summary	This paper presents an ongoing research project about the development of the materials and fabrication techniques for a fundamentally new class of architectural composite. This type of composite, which is a representative example of an even broader class of smart architectural material, has the potential to change the design and function of an architectural structure or living environment. As of today, this kind of composite does not exist. Once completed, this will be the first technology on its own. We believe this study will lay the fundamental groundwork for a new paradigm in surface engineering that may be of considerable significance in architecture, building and construction industry, and materials science.

title	RECONCILING COMPUTER AND HAND: THE CASE OF AUTHOR IDENTITY IN DESIGN PRESENTATIONS
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. 13-22

summary	As computers were newly emerging in the field of architectural design, it was claimed that the impact of computers would change the way architects design and present. However, within the course of computer use in design, although the field of architectural practice might have been altered extremely, in architectural education there still seems to be a bond to conventional mind-hand-paper relation. One of the reasons for that bond is the fact that although being r 1000 elated to many technologies, architecture essentially positions itself around an artistic core that is still fed with conventional modes of creation. Architectural education aims at adopting and working on this very core. One of the major contributors in the formation of this core is the presence of author identity. This paper makes a critical approach to computers in terms of expressing author identity in design presentations especially during design education. We believe that the author identity is important in design education in terms of identifying the potential and skills of the student. Especially in design education the final step of design process turns out to be the presentation, unlike architectural practice where the presented design is actually built. Within this conception, two different studies were held in an educational environment with 160 design students and 20 design instructors. The results of both studies pointed at the fact that the digital opportunities that exist for design education should evolve around preserving and underlining the author identity in design presentations.

title	Digital Tools for Design Learning

summary	There is growing consensus among architectural critics and educators that there exists an increasing divide between the worlds of architectural education and practice. New social and cultural norms, new materials, and current global concerns, like sustainability, have largely influenced the need for an improved balance/integration between design theory and practice. This places schools of architecture around the world under pressure to provide their graduates with the requisite skills that support responsible design characterized by good design thinking strategies. The Caribbean School of Architecture, in addition to being affected by this predicament, has other pressures on its educational offerings. The region’s lack of resources and particular social issues mandates that graduates of the school adopt a responsible attitude towards design in the region. A positive attitude to such issues as sustainability, energy conservation and community will only come about through an effective transmission of particular architectural knowledge that is relevant to the region. The challenge (globally and in the Caribbean), therefore, is the provision of an innovative and effective way of supporting the student master dialogue in studio, facilitating the transfer of “practical, appropriate knowledge” needed by students to create safe, purposeful and responsible architecture. This paper exists within the research paradigm of providing digital teaching tools to beginning students of architecture. This digital research paradigm seeks to move digital technology (the computer) beyond functioning as an instrumental tool (in visualization, representation and fabrication) to becoming a “Socratic machine” that provides an appropriate environment for design learning. Research funds have been allocated to the author to research and develop the information component of the tool with special reference to the Caribbean. The paper will report on the results of prior investigations, describe the reaction and appreciation of the students and conclude with lessons learnt for the further development of the teaching tool.

title	Thonet Chairs Design Grammar: a Step Towards the Mass Customization of Furniture
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. 181-200.
summary	The paper presents the first phase of research currently under development that is focused on encoding Thonet design style into a generative design system using a shape grammar. The ultimate goal of the work is the design and production of customizable chairs using computer assisted tools, establishing a feasible practical model of the paradigm of mass customization (Davis, 1987). The current research step encompasses the following three steps: (1) codification of the rules describing Thonet design style into a shape grammar; (2) implementing the grammar into a computer tool as parametric design; and (3) rapid prototyping of customized chair designs within the style. Future phases will address the transformation of the Thonet’s grammar to create a new style and the production of real chair designs in this style using computer aided manufacturing. Beginning in the 1830’s, Austrian furniture designer Michael Thonet began experimenting with forming steam beech, in order to produce lighter furniture using fewer components, when compared with the standards of the time. Using the same construction principles and standardized elements, Thonet produced different chairs designs with a strong formal resemblance, creating his own design language. The kit assembly principle, the reduced number of elements, industrial efficiency, and the modular approach to furniture design as a system of interchangeable elements that may be used to assemble different objects enable him to become a pioneer of mass production (Noblet, 1993). The most paradigmatic example of the described vision of furniture design is the chair No. 14 produced in 1858, composed of six structural elements. Due to its simplicity, lightness, ability to be stored in flat and cubic packaging for individual of collective transportation, respectively, No. 14 became one of the most sold chairs worldwide, and it is still in production nowadays. Iconic examples of mass production are formally studied to provide insights to mass customization studies. The study of the shape grammar for the generation of Thonet chairs aimed to ensure rules that would make possible the reproduction of the selected corpus, as well as allow for the generation of new chairs within the developed grammar. Due to the wide variety of Thonet chairs, six chairs were randomly chosen to infer the grammar and then this was fine tuned by checking whether it could account for the generation of other designs not in the original corpus. Shape grammars (Stiny and Gips, 1972) have been used with sucesss both in the analysis as in the synthesis of designs at different scales, from product design to building and urban design. In particular, the use of shape grammars has been efficient in the characterization of objects’ styles and in the generation of new designs within the analyzed style, and it makes design rules amenable to computers implementation (Duarte, 2005). The literature includes one other example of a grammar for chair design by Knight (1980). In the second step of the current research phase, the outlined shape grammar was implemented into a computer program, to assist the designer in conceiving and producing customized chairs using a digital design process. This implementation was developed in Catia by converting the grammar into an equivalent parametric design model. In the third phase, physical models of existing and new chair designs were produced using rapid prototyping. The paper describes the grammar, its computer implementation as a parametric model, and the rapid prototyping of physical models. The generative potential of the proposed digital process is discussed in the context of enabling the mass customization of furniture. The role of the furniture designer in the new paradigm and ideas for further work also are discussed.

summary	Information Visualization (InfoVis) is the field devoted to the study of methods for displaying data in information-rich domains. Although most of the InfoVis solutions have been developed by scientists and engineers, artists and designers have began to bring in their expertise to advance the state of the art. The role that architects may play in this development could be substantial. Yet, participating in this new design frontier means to master skills and knowledge not necessarily covered by traditional architectural education. This paper presents a four-year effort devoted to develop such InfoVis curricula in an architectural context. The course encodes knowledge harvested over almost 10 year of InfoVis research bridging 5 disciplines and delivering many successful academic, technological, and commercial products. In particular, the class investigates the use of architecture as (1) a fundamental data organizational device and (2) a research method of examination, response, and communication for InfoVis problems.

title	Multi-user virtual worlds: 3D interactive visualization in synthetic environments for design workshops
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 344-349
summary	The goal of this research is to describe a methodology of architectural design by using digital technology with three-dimensional interactive simulation in multi-user virtual worlds. In addition, this study will focus on the application of this method in the workshops at the School of Architecture in the University of Zulia. With this proposal, it is possible to integrate many users, in real time, from different locations on the same virtual world in Internet. In the same way, each visitor is able to interact and modify the virtual world using virtual menus while sharing ideas or modifications regarding the design of the project. This strategy allows modeling, visualizing, developing and evaluating the designed projects during the conceptual and parametric phase in the process of design. This application is a powerful tool to develop creativity and skills of spatial perception among the students. [Full paper in Spanish]

title	From Bézier to NURBS: Integrating Material and Digital Techniques through a Plywood Shell
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. 156-169

summary	The development of digital fabrication has reintroduced material processes with digital processes. There has been much discussion about the tool and the objects of the tool, but little discussion of the implication of the material process on the digital process. A brief historical review on the development of computer numerical control and the origins of the Bézier curve reveals an instrumental fact: computer numerical controlled tools necessitated advancements in computational surfaces which eventually led to NURBS (Non-Uniform Rational B-Splines) surfaces. In other words, the origins of NURBS surfaces resides in its relation to material processes, rather than many current approaches that develop free form surfaces and then force the tool onto the material without regard to the material properties. From this historical and mathematical review, this project develops toward more intelligent construction methods based on the integration of NURBS differential geometry paired with material qualities and processes. Specifically, a digital technique of developing conceptual NURBS geometry into piecewise surface patches are then flattened based on the material thickness and density. From these flattened patches, a material technique is developed to intelligently remove material to allow the rigid flat material to re-develop into physical surface patches. The goal of this research is to develop digital and material techniques toward intelligent construction based on the correspondence between digitally driven surface and digitally driven material processes. The application of this technique as a rational and flexible system is to support the dynamic response of form and material toward such performative aspects as structure, daylight, ventilation, and thermal properties.

summary	Space designers usually look for information on site before proceeding design. They image any possibilities of design, while they are on site. Restricted to traditional design media, if they want to develop their ideas further, they have to go back to desks. This kind of design process can capture only part of information of the site. Why not do some developments directly when designers are on the site? That is the starting point of this paper. The whole situation of site is very complicated, so it is very difficult discussing all the possibilities. In order to understand how to design on site, reducing the variations is needed. Tsai and Chang (2005) proposed a prototype about design on site, which focuses on land forming. So I chose interior as the site to reduce the variation and have more controllable factors. Still there are many factors effecting design on site, scale is very unique and very important factor of them. Beginners are difficult to really feel how long it is on the plan drawing, and even most advanced VR equipment still can’t fully present the rich information on the site. To experience the site though body, the main idea is how to propose a portable device that can support space designer to do design on site directly, with intuitional body movement and precise scale, and get feedback immediately.

summary	This study reports on the development and experiment of CaseBox for case-based learning. Due to many advantages of the case-based reasoning, the authors create a learning environment for both teachers and students. In the digital era, multimedia and web-based education methodologies emerge auspiciously in schools. Teachers and students no longer satisfy paper-based documents, they research with case-based reasoning on the internet. CaseBox is proposed as a learning environment, which supports: 1) Teachers introduce cases. 2) Students study and reuse cases. 3) Members discuss design on the web. CaseBox is still under development and this study reports on the efforts and discoveries at the recent stage, and shares the debates of ideas and problems of case-based e-Learning.

title	How Real Is the Sense of Presence in A Virtual Environment? : Applying Protocol Analysis for Data Collection
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. 188-197
doi	https://doi.org/10.52842/conf.caadria.2005.188
summary	This study attempts to investigate the sense of presence in a fully immersive virtual environment. The methodology applied in this study used protocol analysis for data collection. A preliminary experiment was conducted to explore noticeable phenomena to develop a hypothesis for the final experiments. Four different virtual reality models, representing four different kinds of virtual space, were navigated in C6 (CAVE facilities) by two human subjects. Results of the research in this direction have provided valuable understanding regarding the sense of presence in the virtual environment.

title	Architecture and Biological Analogies
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 599-606

summary	The study described in this paper evolves within the larger context of a research aimed at inquiring into analogies between architecture and nature, and more specifically between architecture and biology. Biology is a recursive source of architectural inspiration due to the tight relationship between form and function, the natural balance of forces and the corresponding geometric solutions found in living beings. Roughly, one can classify historical analogies between architecture and biology into two main categories. The first tries to mimic biological forms and the second biological processes. The specific goal of the described study is to find how new technologies can redefine and support the process of constructing such analogies. It uses as a case study a tower project designed by the architect Manuel Gausa (ACTAR, Barcelona) called Tornado Tower because of its complex shape inspired in the frozen form of a tornado. Due to the geometric irregularities of the tower, Gausa’s team had difficulties in designing it, especially because solving the structural problems required constant redrawing. This paper describes the first part of the study which primary goal was to conceive a parametric program that encoded the overall shape of the Tornado Tower. The idea was to use the program to simplify the drawing process. This required a mathematical study of spirals and helices which are at the conceptual basis of the external structure and shape of the tower. However, the program encodes not only the shape of Gausa’s tower, but also the shapes of other buildings with conceptual similarities. Such class of shapes is very recurrent in nature with different scales and with different utilities. Therefore, one can argue that the program makes a mathematical connection between a given natural class of shapes and architecture. The second part of the study will be devoted to extending the program with a genetic algorithm with the goal of guiding the generation of solutions taking into account their structural fitness. This way, the analogy with genetic procedures will be emphasized by the study of the evolution of forms and its limits of feasibility. In summary, the bionic shape analogy is made by the generation of mimetic natural forms and a genetic process analogy starts with the parametric treatment of shape based on code manipulations. At the end the program will establish an analogy between architecture and biology both terms of form and process.
