summary RaBBiT (Requirements Building for Building Types) provides computational support for architectural programming or requirements modeling in building design. A highly interactive graphical user interface (GUI) allows users to adapt RaBBiT to various programming styles and terminologies. Since users are not expected to have any prior computer programming experience, the design of RaBBiT’s GUI posed particular challenges, which we attempted to meet through a direct-manipulation interface based on the model-world metaphor.

title Interaction Protocol for Questions & Answers through Screen Capture, in Virtual Learning Environments
source SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary Virtual Environments for Learning typically include a FAQ (frequently asked questions) repository, built up from interactions between students and teachers. Based on Media Richness Theory, there is evidence that dynamic audiovisual demonstrations show advantages over text and still-image based tutorials. A protocol with a structured modus operandi seems suitable for those interactions. This paper accounts for a project startup, which will compare two communication procedures for building a low cost FAQ repository with screen-capture software CamStudio and YouTube. Six sample courses will compare highly structured protocol and a low one. We expect evidence in favor of a more structured protocol.

title A Computer-based Approach for Teaching Daylighting at the Early Design Stage
source Education for Practice [14th eCAADe Conference Proceedings / ISBN 0-9523687-2-2] Lund (Sweden) 12-14 September 1996, pp. 181-190
summary This paper has reviewed the literature on the teaching of daylight systems design in architectural education, and found that traditionally such teaching has evolved around the prediction of the Daylight Factor (DF%), i.e. illuminance, via two methods one studio-based and another laboratory based. The former relies on graphical and/or mathematical techniques, e.g. the BRE Protractors, the BRE Tables, Waldram Diagrams, the Pepper-pot diagrams and the BRE formula. The latter tests scale models of buildings under artificial sky conditions (CIE sky). The paper lists the advantages and disadvantages of both methods in terms of compatibility with the design process, time required, accuracy, energy-consumption facts, and visual information.

This paper outlines a proposal for an alternative method for teaching daylight and artificial lighting design for both architectural students and practitioners. It is based on photorealistic images as well as numbers, and employs the Lumen Micro 6.0 programme. This software package is a complete indoor lighting design and analysis programme which generates perspective renderings and animated walk-throughs of the space lighted naturally and artificially.

The paper also presents the findings of an empirical case study to validate Lumen Micro 6.0 by comparing simulated output with field monitoring of horizontal and vertical illuminance and luminance inside the highly acclaimed GSA building in Glasgow. The monitoring station was masterminded by the author and uses the Megatron lighting sensors, Luscar dataloggers and the Easylog analysis software. In addition photographs of a selected design studio inside the GSA building were contrasted with computer generated perspective images of the same space.

title The Design and Evaluation of Transparent User Interfaces. From Theory to Practice
source University of Toronto, Toronto
summary The central research issue addressed by this dissertation is how we can design systems where information on user interface tools is overlaid on the work product being developed with these tools. The interface tools typically appear in the display foreground while the data or work space being manipulated typically appear in the perceptual background. This represents a trade-off in focused foreground attention versus focused background attention. By better supporting human attention we hope to improve the fluency of work, where fluency is reflected in a more seamless integration between task goals, user interface tool manipulations to achieve these goals, and feedback from the data or work space being manipulated. This research specifically focuses on the design and evaluation of transparent user interface 'layers' applied to graphical user interfaces. By allowing users to see through windows, menus, and tool palettes appearing in the perceptual foreground, an improved awareness of the underlying workspace and preservation of context are possible. However, transparent overlapping objects introduce visual interference which may degrade task performance, through reduced legibility. This dissertation explores a new interface technique (i.e., transparent layering) and, more importantly, undertakes a deeper investigation into the underlying issues that have implications for the design and use of this new technique. We have conducted a series of experiments, progressively more representative of the complex stimuli from real task domains. This enables us to systematically evaluate a variety of transparent user interfaces, while remaining confident of the applicability of the results to actual task contexts. We also describe prototypes and a case study evaluation of a working system using transparency based on our design parameters and experimental findings. Our findings indicate that similarity in both image color and in image content affect the levels of visual interference. Solid imagery in either the user interface tools (e.g., icons) or in the work space content (e.g., video, rendered models) are highly interference resistant and work well up to 75% transparent (i.e., 25% of foreground image and 75% of background content). Text and wire frame images (or line drawings) perform equally poorly but are highly usable up to 50% transparent, with no apparent performance penalty. Introducing contrasting outlining techniques improves the usability of transparent text menu interfaces up to 90% transparency. These results suggest that transparency is a usable and promising interface alternative. We suggest several methods of overcoming today's technical challenges in order to integrate transparency into existing applications.

title Amor Infiniti/Horror Vacuii: Resolving Architecture Beyond the Planck Length ()
source III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 19-24
summary If one were to presume that every major shift in the perception and representational modes of architecture has its mirror in what is made, then we should be able to divine and critique the implications of making architecture through information technologies. We are only now beginning to enter speculations of what can possibly be made as a direct result of these systems. Already, the representation of digital space is undergoing a fundamental transition: From the highly precise facsimile of traditional Euclidean geometry, that we currently use in most CAD and modelling software to the visual interpretation of dense data arrays, as is emerging in GIS (Global Information Systems). This shift from a Vectorial world to a bitmap world is perhaps the most challenging to our historical and perhaps necessary assumption that Euclidean geometry , such as proportion and projection, is at the heart of making architecture. Does this shift imply an ultimately fatal divorce from the Vitruvian tradition of architecture through geometry or is it re-directing the interaction between computers and architecture into perhaps a more appropriate and creative realm of opportunity? This paper hopes to address these questions in the forum of a theoretical and historical discussion focused on the representation of architecture and making. Some current experimental digital work by the author will accompany this presentation and paper.

source Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 518-529
summary This paper follows the technical problematic of the hexEnvelope, a novel system for building complex geometric objects. Operating as a scripted system of parametric operations, and running through multiple 2D, 3D, and fabrication software packages, the hexEnvelope system allows for a highly tectonic assemblage of cellular units. Specific issues addressed within the system include the realization of curved surfaces through flat material, the embedding of fabrication logic and material performance within descriptive geometry, and multiple scales of deployment in terms of their tectonic and material consequence.

title Dry-In House: A Mass Customized Affordable House for New Orleans
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 359-362
summary Dry-in house is a mass customized affordable housing system proposed for the reconstruction of New Orleans. The dry-in House gets the owner back to their home site quickly while providing the infrastructure an occupant needs (shelter, water, electricity). The owner is supplied with an inhabitable shell that is customizable before it is fabricated as well as onsite as the project is “fitted out” over time. The key concept is to allow families to participate in the design of their customized homes and to get people back to their home sites as quickly as possible and to give them the opportunity to finish and further customize their home over time. The project addresses inefficiencies and redundancies in emergency housing currently provided by FEMA. Primarily the dry-in House as its name implies provides a timely dried-in space which doubles as a customized infrastructure for the reconstruction of homes and neighborhoods. The project is designed to meet the $59,000 life cycle cost of the presently provided temporary housing, the notorious “FEMA Trailer”. However, the Dry-in House provides a solution that: a) Is permanent rather than temporary. The house will be finished and further customized over time rather than disposed of. b) Reoccupies the owner’s home site rather than a “FEMA ghetto” keeping the community together and functioning. c) Is mass customized rather than mass-standardized allowing the owner to have input on the design of their home. The design is a “starter home” rather than an inflexible and over-determined solution. This also has the benefit of giving variation to the reconstruction of New Orleans as opposed to the monotony of mass-production. d) Allows the owners to further customize their home over time with additional exterior finishes and the subdivision and fit out of the interior. By utilizing plate truss technology and associated parametric modeling software, highly customized trusses can be engineered and fabricated at no additional cost as compared to off-the-shelf trusses. This mass customization technology is employed to create the building section of each individual’s house. The truss is not used in its typical manner, spanning over the house; rather, it is extruded in section to form the house itself (roof, wall, and floor). Dry-in House exploits this building technology to quickly rebuild communities in a sensible manner. It allows for an increased speed of design and construction and most importantly it involves the owner in this process. The process has other benefits like reducing waste not only because it replaces the FEMA trailer which is expensive and disposable but also since the components are prefabricated there is more precision and also quality. The Dry-in House allows the owner-designer to “draw” the section of their new home providing them with a unique design and a sense of belonging and security. The design of the section of the house also provides them with spatial configurations customized relative to site conditions, program etc... Because of the narrow lot configuration of New Orleans, the design maximizes the roof as a source for natural ventilation and light for the interior of the house. In addition, the house is one room deep providing cross ventilation in all rooms minimizing reliance on artificial mechanical systems. The timely and efficient off site fabrication of building sections facilitate larger concentrations of volunteers on site at one time, thereby promoting a greater collective spirit among the community and volunteer workforce, a therapeutic event for the community as they participate in the rebuilding of their homes and city. With individualized building sections arriving on site, the construction process is imagined to be more akin to a barn raising, making possible the drying in of multiple houses in less than one day.

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—like other designers—tend 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—in the way architecture is conceived, taught and critiqued—results 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 “movement”, “guiding” and/or “rest” 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 A Computer-Facilitated Approach for Development, Visualization and Testing of Functional Programming Information
source Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary Functional programming processes for complex architectural projects have traditionally been hampered by the static nature of available tools and technologies. Connection with user groups have likewise been disadvantaged through the employment of sender-oriented communications models that limit feedback and interaction. In addition, diminishing project budgets place increasing pressure on clients and consult-ants to develop more effective and efficient methods for the design and construction of buildings. This paper discusses a case-study involving the design of a highly complex medical laboratory wherein infoc mation technologies were used to facilitate the development, visualization and testing of functional pro-gramming information. The objectives for the project involved creating an environment where users and clients actively participate in consideration of programming directions and implications in a manner that would not only increase confidence that the program would meet user requirements now and in the future, but also would reduce redundant and or inefficient space within the overall building programme. In the approach used the distinction between programming and design is diminished to improve communication of desires and design responses. The findings of the study indicate that the computer-facilitated approach met the objectives of the project and that the methods developed hold promise for application across a broader range of project types.

title Visual Intelligence
source Norton Publishing, New York
summary After his stroke, Mr. P still had outstanding memory and intelligence. He could still read and talk, and mixed well with the other patients on his ward. His vision was in most respects normal---with one notable exception: He couldn't recognize the faces of people or animals. As he put it himself, "I can see the eyes, nose, and mouth quite clearly, but they just don't add up. They all seem chalked in, like on a blackboard ... I have to tell by the clothes or by the voice whether it is a man or a woman ...The hair may help a lot, or if there is a mustache ... ." Even his own face, seen in a mirror, looked to him strange and unfamiliar. Mr. P had lost a critical aspect of his visual intelligence. We have long known about IQ and rational intelligence. And, due in part to recent advances in neuroscience and psychology, we have begun to appreciate the importance of emotional intelligence. But we are largely ignorant that there is even such a thing as visual intelligence---that is, until it is severely impaired, as in the case of Mr. P, by a stroke or other insult to visual cortex. The culprit in our ignorance is visual intelligence itself. Vision is normally so swift and sure, so dependable and informative, and apparently so effortless that we naturally assume that it is, indeed, effortless. But the swift ease of vision, like the graceful ease of an Olympic ice skater, is deceptive. Behind the graceful ease of the skater are years of rigorous training, and behind the swift ease of vision is an intelligence so great that it occupies nearly half of the brain's cortex. Our visual intelligence richly interacts with, and in many cases precedes and drives, our rational and emotional intelligence. To understand visual intelligence is to understand, in large part, who we are. It is also to understand much about our highly visual culture in which, as the saying goes, image is everything. Consider, for instance, our entertainment. Visual effects lure us into theaters, and propel films like Star Wars and Jurassic Park to record sales. Music videos usher us before surreal visual worlds, and spawn TV stations like MTV and VH-1. Video games swallow kids (and adults) for hours on end, and swell the bottom lines of companies like Sega and Nintendo. Virtual reality, popularized in movies like Disclosure and Lawnmower Man, can immerse us in visual worlds of unprecedented realism, and promises to transform not only entertainment but also architecture, education, manufacturing, and medicine. As a culture we vote with our time and wallets and, in the case of entertainment, our vote is clear. Just as we enjoy rich literature that stimulates our rational intelligence, or a moving story that engages our emotional intelligence, so we also seek out and enjoy new media that challenge our visual intelligence. Or consider marketing and advertisement, which daily manipulate our buying habits with sophisticated images. Corporations spend millions each year on billboards, packaging, magazine ads, and television commercials. Their images can so powerfully influence our behavior that they sometimes generate controversy---witness the uproar over Joe Camel. If you're out to sell something, understanding visual intelligence is, without question, critical to the design of effective visual marketing. And if you're out to buy something, understanding visual intelligence can help clue you in to what is being done to you as a consumer, and how it's being done. This book is a highly illustrated and accessible introduction to visual intelligence, informed by the latest breakthroughs in vision research. Perhaps the most surprising insight that has emerged from vision research is this: Vision is not merely a matter of passive perception, it is an intelligent process of active construction. What you see is, invariably, what your visual intelligence constructs. Just as scientists intelligently construct useful theories based on experimental evidence, so vision intelligently constructs useful visual worlds based on images at the eyes. The main difference is that the constructions of scientists are done consciously, but those of vision are done, for the most part, unconsciously.

summary This paper presents an approach for familiarizing architecture students with concepts of environmental performance in the early design stages. A design studio was run at the University of Technology Sydney by Leena Thomas and the author where students were applying building performance analysis to inform their design process from the very beginning of the semester. Students were using parametric design and evolutionary structural optimization in conjunction with environmental performance optimization. Michael Hensel and Defne Sunguroglu (Ocean North) joined the studio at half time for a workshop to investigate how processes occurring in nature can be mapped to inform the morphological design process. In spite the multitude of challenges put to the students during the semester in regard to their design methodology and techniques, they were able to produce highly performative and aesthetically pleasing design outcomes.

summary The construction and building sector is now widely known to be one of the biggest energy consumers, carbon emitters, and creators of waste. Some architectural agendas for sustainability focus on energy efficiency of buildings that minimize their energy intake during their lifetime - through the use of more efficient mechanical systems or more insulative wall systems. One issue with these sustainability models is that they often ignore the hierarchy of energy within architectural design. The focus on the efficiency is but one aspect or system of the building assembly, when compared to the effectiveness of the whole, which often leads to ad-hoc ecology and results in the all too familiar “law of unintended consequences” (Merton, 1936). As soon as adhesive is used to connect two materials, a piece of trash is created. If designers treat material as energy, and want to use energy responsibly, they can prolong the lifetime of building material by designing for disassembly. By changing the nature of the physical relationship between materials, buildings can be reconfigured and repurposed all the while keeping materials out of a landfill. The use of smart joinery to create building assemblies which can be disassembled, has a milieu of new possibilities created through the use of digital manufacturing equipment. These tools afford designers and manufacturers the ability to create individual joints of a variety of types, which perform as well or better than conventional systems. The concept of design for disassembly is a recognizable goal of industrial design and manufacturing, but for Architecture it remains a novel approach. A classic example is Kieran Timberlake's Loblolly House, which employed material assemblies “that are detailed for on-site assembly as well as future disassembly and redeployment” (Flat, Inc, 2008). The use of nearly ubiquitous digital manufacturing tools helps designers create highly functional, precise and effective methods of connection which afford a building to be taken apart and reused or reassembled into alternative configurations or for alternative uses. This paper will survey alternative energy strategies made available through joinery using digital manufacturing and design methods, and will evaluate these strategies in their ability to create diassemblable materials which therefore use less energy - or minimize the entropy of energy over the life-cycle of the material.

source Mission - Method - Madness [ACADIA Conference Proceedings / ISBN 1-880250-01-2] 1992, pp. 195-206
summary Energy performance is a crucial step toward responsible design. Currently there are many tools that can be applied to reach this goal with reasonable accuracy. Often times, however, major flaws are not discovered until the final stage of design when it is too late to change. Not only are existing simulation models complicated to apply at the conceptual design stage, but energy principles and their applications are also abstract and hard to visualize. Because of the lack of suitable tools to visualize energy analysis output, energy conservation concepts fail to be integrated into the building design. For these reasons, designers tend not to apply energy conservation concepts at the early design stage. However, since computer graphics is a new phase of visual communication in design process, the above problems might be solved properly through a computerized graphical interface in the conceptual design stage.

The research described in this paper is the result of exploring the concept of using computer graphics to support energy efficient building designs. It focuses on the visualization of building energy through a highly interactive graphical interface in the early design stage.

summary Understanding of people's spatial behavior is fundamental to architectural and urban design. However, traditional investigation methods applied in environmental behavior studies is highly limited regarding the amount of samples and regions it covers, which is not sufficient for the exploration of complex dynamic human behaviors and social activities in architectural space. Only recently the developments in indoor positioning system (IPS) and big data analysis technique have made it possible to conduct a full-time, full-coverage study on human environmental behavior. Among the variety IPS systems, the Wi-Fi IPS system is increasingly widely used because it is easy to be applied with acceptable cost. In this paper, we analyzed a 60-days anonymized data set, collected by a Wi-Fi IPS system with 110 Wi-Fi access points. The analysis revealed interesting patterns on people's behavior besides temporal spatial distribution, ranging from the cyclical fluctuation in human flow to behavioral patterns of sub-regions, some of which are not easy to be identified and interpreted by the traditional field observation. Through this case study, behavioral data from IPS system has exhibited great potential in bringing about profound changes in the study of environmental behavior.

title Design Problems and Evaluative Strategies Using CAAD
source February, 1990. 16 p. : col. ill. includes bibliography
summary The way architects design comes into sharp focus when developing strategies for evaluating buildings. Architectural design is a highly subjective activity on the one hand but on the other it is also highly objective. The paper examines the use of CAAD systems for objective evaluation while also recognizing that this kind of evaluation has to be related to the subjective aspects of the design. In order to examine this, further research has been carried out into the use of CAAD systems to evaluate sunshading characteristics in a building design problem. The approach utilized the Integraph AMOD software to generate three dimensional models of the design proposal which were then tested using the Integraph Model View software which has a sunshading facility. The utility of this approach was tested first against criteria of how accurate the computer was in giving meaningful feedback to the designer. Secondly, how productive this approach was in the design process as compared to traditional techniques using instruments such as the heliodon. Finally, a discussion of the developments of the approach is given

summary This communication addresses the use of a new type of referents database in the context of an architectural design studio. It discusses the results of design experiences held with the objective to study the cognitive effects of a teaching approach based on precedents and metaphors available as interactive and reusable digital models to students. The introduction of this referent-based approach is inspired by three major principles: the largely accepted fact that the creative work of architects is highly supported by referring to precedents and metaphors; the use of algorithmic digital methods to encapsulate architectural knowledge; and the constructivist approach to architectural design education. The study finds that the role of the modeled referents is helpful for the design studio learning, and that they are most creatively used when internalized by the student.

summary The importance of decisions made during the early design stages has prompted researchers to advocate the use of building performance simulation (BPS) during that stage. This paper investigates non-manifold topology (NTM) as a novel approach to 3D modelling that has the potential to be highly compatible with the early design stages and with the input requirements for BPS. The proposed approach avoids the process of simplifying polyhedral models produced by Building Information Modelling (BIM) software to conduct BPS. In particular, NTM allows for a clear segmentation of a building, unambiguous space boundaries, and perfectly matched surfaces and glazing subsurfaces. The NTM approach was tested through a software prototype that integrates 3D modelling software and an energy simulation engine.

summary Design is a fundamentally collaborative activity. It commonly calls on a wide range of expertise and is arguably most effective when all contributions can be considered from an early and highly conceptual phase of the process. The sharing of information, particularly in a process that, at its best, involves collective conceptualisation is complicated by the very close and reciprocal relationship between the partial knowledge about the object of design and the mode of expression or representation of these ideas. As the design process and its numerous inputs, iterations and interrelationships become embedded in the communications; knowledge capture, management and access become central issues. This paper will selectively recount some of the substantive evidence for the characteristics of communication environments most supportive to design collaboration. In response to these findings it will introduce the use of wiki as the basis of an environment to provide this support, provide more detailed examples of the ways in which wiki has been adopted in early collaborative experiments and describe the developments currently being implemented, and how these are being tested in use.

title Evolutionary design systems: a conceptual framework for the creation of generative processes
source Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary This paper presents an conceptual framework for the construction of generative mapping processes as a basis for creating active design tools in the domain of architecture. Such generative processes are seen as key components within evolutionary systems that manipulate populations of alternative solutions in order to discover previously unexplored possibilities. Solutions are represented in two forms: as highly encoded genotypes referred to as design seeds and as decoded phenotypes referred to as design proposals. The generative process maps the design seed to the design proposal. The discussion of generative processes is in two parts. In the first part it is argued that any generative process that aims to create a wide range of solutions that differ from each other in fundamental ways must focus on a limited subcategory of possible designs. It is proposed that the endeavour to create active design tools demands that the focus be on the designer's highly personalised style, called a design-schema. The second part discusses how to uncover the essence of an architectural design-schema. In particular, it is argued that implicit and familiar aspects of buildings must be scrutinised in order to reveal the knowledge that is essential to capturing and codifying a design-schema. A range of rationalisations and conceptualisations of built form are presented with examples to illustrate possible routes of analysis. Finally, in conclusion, the possibility of discovering universal generators common to many divers generative processes are discussed.
