title	A Multi-Disciplinary Design Studio using a Shared IFC Building Model
source	Computer Aided Architectural Design Futures 2005 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-3460-1] Vienna (Austria) 20–22 June 2005, pp. 445-454
summary	This paper reports on a multi-disciplinary building design studio where a shared IFC (Industry Foundation Classes) building model was employed to support a collaborative design process in a studio-teaching environment. This project began with the premise that the efforts over the past decade of the International Alliance for Interoperability (IAI) to develop a genuinely operational building model schema has resulted in a mature technology that is now ready to be applied. This design studio experience sought to test that premise. The paper discusses the background to the idea of design collaboration based on a shared building model, placing this current work within that context. We look at both the nature of design decision-making, as well as the process opportunities afforded by close multi-disciplinary collaboration and rapid feedback from design analysis. Although the work was undertaken in a teaching context, the paper does not discuss the pedagogical issue, but rather concentrates on the operational issues that are encountered when working with a shared building model during a design process. The paper concludes with a statement of the lessons learnt and strategies to be adopted in future projects of this nature.

title	Multidisciplinary Design in Virtual Worlds

summary	Large design projects, such as those in the AEC domain, involve collaboration among a number of design disciplines, often in separate locations. With the increase in CAD usage in design offices, there has been an increase in the interest in collaboration using the electronic medium, both synchronously and asynchronously. The use of a single shared database representing a single model of a building has been widely put forward but this paper argues that this does not take into account the different representations required by each discipline. This paper puts forward an environment which provides real-time multi-user collaboration in a 3D virtual world for designers in different locations. Agent technology is used to manage the different views, creation and modifications of objects in the 3D virtual world and the necessary relationships with the database(s) belonging to each discipline.

title	A Representation Language for a Prototype CAD Tool for Intelligent Rooms
doi	https://doi.org/10.52842/conf.acadia.2005.170
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. 170-183
summary	Intelligent rooms are a type of intelligent environment which enhance ordinary activities within the confines of a room by responding to human interaction using pervasive and ubiquitous computing. In the design of intelligent rooms, the specification of how the intelligent room enacts intelligent behavior through computational means is as integral as the geometric description. The self-aware and context-aware capabilities of intelligent rooms extend the requirements for computer-aided design tools beyond 3D modeling of objects. This article presents a Hardware as Agents Description Language for Intelligent Rooms (HADLIR) to model hardware in an intelligent room as “hardware agents” having sensor and/or effector modalities with rules and goals. End-users describe intelligent room hardware as agents based on the HADLIR representation and write agent rules and goals in Jess for each hardware component. This HADLIR agent description and the requisite software sensors/effectors constitute “hardware agents” which are instantiated into a multi-agent society software environment. The society is then bridged to either a virtual environment to prototype the intelligent room or to microelectronic controllers to implement a physical intelligent room. The integration illustrates how the HADLIR representation assists in the design, simulation and implementation of an intelligent room and provides a foundation technology for CAD tools for the creation of intelligent rooms.

title	Digitally Documenting D-Day: The use of Close Range Digital Photogrammetry at Pointe du Hoc
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 2, pp. 634-639
summary	This paper describes the progress of a multi-disciplinary team from Texas A&M University to digitally document the command post at one of the most significant historic sites of the D-Day landings: Pointe du Hoc. The methods used to collect survey data for both the production of 2D Historic American Building Survey drawings and for the 3D digital model are described. The processes used to produce the 3D digital model involves collecting survey data using digital photogrammetry and then applying surfaces to that model using modeling software. The results of the first season’s survey work are described and illustrated. Finally, the problems encountered with lighting and the digital photogrammetry processing are discussed and recommendations made for future work.

title	Collective Pavilions: A Generative Architectural Modelling for Traditional Chinese Pagoda
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. 129-138
summary	This paper investigates generative architectural modelling for traditional Chinese architecture and aims to explore and extend the potential of adaptive computing for architectural design methods. The design manners analysis of traditional pagodas architectures is made in a holistic view and under historical perspective. We propose a descriptive model and generative system for the design of traditional Chinese pagodas, by which each pagoda is defined as a collection of style-matched and form-coordinated pavilions and described by both topological graphs and variant geometrical units. Our approach models both of the building geometry and space organization/spatial patterns of pagodas separately. The generative mechanism consists of a framework of grammar-based design and parametric, recursive shape computation. Accordingly, the generative algorithm is also made of two levels, the topology of spatial patterns and the shape geometrical parameters that characterize pavilion variations. The algorithm for computing the former is based on GP (Genetic Programming) and the latter GA (Genetic Algorithms). To explore the collective behaviour of a group of pavilions, multi-agent modelling approach is incorporated in composition patterns search. A prototype system, 'glPagoda', using the OpenGL graphics library for rendering and visualization, has been developed and implemented on PC windows platform.

title	Towards a BIM-Based Energy Rating System
doi	https://doi.org/10.52842/conf.caadria.2014.285
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	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	University faculty -adult culture- work from the logic that goes through their speech, didactic model and strategies, providing special links with: the aim of knowledge, transmission mechanisms and technological medium. Students -young culture- receive and deal with knowledge mechanisms from a new logic. In a multimedia framework they establish interpretations using technological medium from semantic decodification. Young graduates, assistants, studio leaders -intermediate culture- coming from traditional learning models with acquired abilities in digital media, are a “potential interface” between both cultures. The impact between fields and cultures implies limitations and risks that may encourage change. A discourse about “new didactic configurations” from the point of view of these three cultures makes possible the exploration of other ways of teaching. Therefore the articulation of teacher-student interrelations and media promotes the development of teaching-learning techniques. [Full paper in Spanish]

title	Three-Dimensional Shape Generation of Low-Energy Architectural Solutions using Pareto Genetic Algorithms
doi	https://doi.org/10.52842/conf.ecaade.2005.647
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 647-654
summary	This paper extends on a previous work on the application of a Generative Design System [GDS] to the evolution, in a computational environment, of three-dimensional architectural solutions that are energy-efficient and adapted to the climatic environment where they are located. The GDS combines a well-known building energy simulation software [DOE2.1E] with search procedures based on Genetic Algorithms and on Pareto optimization techniques, successfully allowing to tackle complex multi-objective problems. In the experiments described, architectural solutions based on a simplified layout were generated in response to two often-conflicting requirements: improving the use of daylighting in the space, while controlling the amount of energy loss through the building fabric. The choice of a cold climate like Chicago provided an adequate framework for studying the role of these opposing forces in architectural form generation. Analysis of results shows that building characteristics that originate successful solutions extend further than the building envelope. Issues of massing, aspect ratio, surface-to-volume ratio, orientation, and others, emerge from the analysis of solutions generated by the GDS, playing a significant role in dictating whether a given architectural form will prove adapted to its climatic and energy requirements. Results suggest that the questions raised by the exploration of form generation driven by environmental concerns are complex, deserving the pursuit of further experiments, in order to better understand the interaction of variables that the evolutionary process congregates.

title	A Quantitative Method to Compare the Impact of Design Mediums on the Architectural Ideation Process.

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.

summary	4D CAD systems are used by contractors for visually checking the construction process. To enable simulation of the construction process, the construction planner links building components from a CAD model with the activities from a project planning. In this paper we describe a method to generate a project planning directly from a CAD model using basic construction knowledge. A case study is discussed briefly to show the current results and the shortcomings. Finally an outlook is presented on a more advanced implementation that is (also) useful for designers.

title	Teaching Programming for and with Microcontroller-Enhanced Physical Models
source	International Journal of Architectural Computing vol. 3 - no. 1, 57-74
summary	As processes of use, interaction and transformation take center stage in various fields of design, electronic sensors, controllers, displays and actuators can significantly enhance the value of physical models. These technologies allow the development of novel computer interfaces for new kinds of interaction with virtual models, and in the future they can be expected to play an important role in the development of new types of active building components and materials for automated construction and dynamic runtime adaptations of inhabitable environments. However, embedding programmed logic into physical objects involves skills outside the traditional domains of expertise of designers and model makers and confronts them with a steep learning curve. The wide variety of alternative technologies and development tools available in this area has a particularly disorienting effect on novices. However, some early experiences suggest that mastery of this learning curve is easily within reach, given some basic introduction, guidance and support. To assist design students in acquiring a basic level of programming knowledge, better educational programming tools are still required. It is the intent of this paper to provide designers and educators with a starting point for explorations into this area as well as to report on the development of an educational approach to electronics programming called haptic programming.

title	A DISTRIBUTED MODEL FOR TACIT DESIGN KNOWLEDGE EXCHANGE
source	SID 2005, Proceedings of the 4th Social Intelligence Design Workshop, Stanford University, March 2005 (CD Rom)
summary	The distributed cognition approach, and by extension the domain of social intelligence design, attempts to integrate three until recently separate realms: mind, society, and matter. The field offers a heterogeneous collection of ideas, observations, and case studies, yet lacks a coherent theoretical framework for building models of concrete systems and processes. Despite the intrinsic complexity of integrating individual, social and technologically-supported intelligence, the paper proposes a relatively simple ‘connectionist’ framework for conceptualizing a distributed cognitive system. This framework represents shared information sources (documents) as nodes connected by links of variable strength, which increases interactively with the number of co-occurrences of documents in the patterns of their usage. This connectionist learning procedure captures and uses the implicit knowledge of its community of users to help them find relevant information, thus supporting an unconscious form of exchange. The principles are illustrated by an envisaged application to a concrete problem domain: the dynamic sharing of design knowledge among a multitude of architects through a database of associatively connected building projects.

title	Improving Design using Autonomous Spatial and Structural Generators
doi	https://doi.org/10.52842/conf.ecaade.2005.743
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 743-750
summary	During a building design process, a structural designer transforms a spatial design into a structural design and this structural system can be improved by optimisation methods or expert views of other structural designers. The improved structural system allows the architect a new spatial design, which can be transformed or altered again by the architect. This design cycle can be repeated several times and is defined as interaction of spatial and structural design. Case studies are used to demonstrate that this interaction occurs in practice and is needed to improve building quality. This paper presents a program with more or less autonomous spatial and structural generators. Each generator will facilitate one direction in the interaction process. Then using both consecutively leads to a design method that provides interaction between spatial and structural design. For the spatial generator, named “room positioning with structural constraints” a space allocation technique is used including constraints that handle structural boundary conditions. A zone generator based on pattern recognition and shape grammars handle the structural design. A Prolog-2 program was developed to demonstrate the application of the two proposed generators. “Zone generation” is performed per building storey and thus represents a horizontal two-dimensional procedure. Similarly “room positioning with structural constraints” is a planar vertical operation. In future these procedures can be made three-dimensional.

summary	The main purpose of this paper is to demonstrate that new computer and communication technology has the potential to change architectural education in a positive way, based on previous experiences and learning from the past. This research is based on two historical aspects that we bring together in order to propose a new didactic method and material for architectural education: the first one consists in finding obsolete architectural training practices and reconsidering them from a modern point of view; the second one proposes using precedents in a new constructive way in situation of teaching architectural conception in studio. This historical approach, combined with architectural design studio observations, has lead to an outline of a prototype of a digital assistant for teaching architectural design. Some aspects of its functioning are here discussed.

title	From CAD to VR – Implementations for Urban Planning and Building Design
doi	https://doi.org/10.52842/conf.ecaade.2005.399

summary	At present time, three-dimensional objects are often represented with 2D-data in urban planning and building design. In order to get all the involved parties to fully understand a certain project, this may not be enough. More and more projects therefore take use of the Virtual Reality (VR) technique as a complement to traditional 2D drawings and sketches. All the involved parties can then share a common frame of reference for all discussions regarding a certain project. Unfortunately, the technique is not yet adapted to fit the current building design process. In this paper, we present a solution for semi-automatic generation of a VR-model based on 3D CAD information and aerial photos obtained from the City Planning Authorities in Sweden. The data is imported to support real-time editing of terrain, roads and buildings. We also present a framework for importing 3D-models created in Autodesk Revit which enables a seamless integration of modern 3D CAD and VR-models. The features are implemented in a software developed at Chalmers Visualization studio (Gothenburg, Sweden) and technical details about terrain handling and speed-up techniques will be given.

summary	We consider a digital diary of a building to be a system for flexibly retrieving and updating building information over the life cycle of the building – a system that is independent of any task-centric use. The key challenges to realizing such a system are the users and their intensions. For a practical demonstration of the notion we use IFC as the protocol for representing a building information model space and the concept of sorts to embrace representational flexibility. The ideas for the digital diary stem from four real construction case studies which we undertook as part of an on-going research project.

summary	Collaboration in design can take place in a physical, social space, in a distributed or virtual environment, or in a combination of both. Design teams use a range of ICT means to support both synchronous and asynchronous communication. While these tools are designed to facilitate collaboration, the collaboration process still requires planning and organisation in a social context, which are activities that students and professionals need to learn. In current practice there is a need for designers and design managers who have the competences to collaborate in design and to organise distributed collaboration processes. At the department of Architecture, Building, and Planning at Eindhoven University of Technology, we have developed a course on Collaborative Design in the Master of Science curriculum. This course addresses both the organisational, social, and technical issues of collaboration in design. The paper introduces the objectives and educational methods used in this course. It describes the experiences of both teachers and students that were gained now that the course was taught in three subsequent years.

summary	As the first design-build-fabricate-assemble experiment at our school, the intent of the studio was to design a framework from which to examine a “lived space” through digital-to-digital processes. Moving from digital models and physical stereo lithographic models to hand-fabrication and digital assembly allowed the students to move from creation to completion. As part of our holistic design process, the studio fabricated almost all components for the project. These elements include the wood flooring, the copper and wood skins, the building’s structural panels, and the two-story light vortex. This single-family, in-fill house is located within an historic downtown neighborhood and is subject to historic district zoning regulations, design guidelines, and Board of Architecture Review approvals. The project is analogous to design challenges presenting themselves in historic districts throughout the United States including the Savannah, Georgia site for the 2005 ACADIA Conference. The scale of the project relates well to the horizontal nature of this context and after a formal, televised review process with the local Board of Architecture Review, the project represents a dynamic, yet sympathetic architectural dialogue with the surrounding buildings. The project develops simultaneously from the exterior and interior resulting in two courtyards that mediate the urban “front door” and the private “terrace.” The students designed these areas through a series of two-dimensional axonometric drawings, three-dimensional physical and digital models, and four-dimensional time-based animations. The building massing separates into two core elements: gabled copper volume and wood screen volume. These elements maintain their conceptual purity by using the same types of modulations on their skins. The copper form with its deep-cut reveals and proportionally placed light scoring patterns reflects the horizontal datum lines of the floor, sill, threshold, and ceiling. In contrast, the wood volume reflects these same lines as applied “shadow screens” which create depths that seamlessly tie together the side, rear, and front facades.The hinge point of the house is the light vortex. Designed in Rhino, translated in Catia, fabricated out of aluminum, and clad in stainless steel, this two-story sculptural element will literally wrap light around its surfaces. Like a sunflower, the light vortex, with its angel hair stainless steel finish, responds to the incremental differentiation of light throughout the day. Photosensitive floor-mounted lights designed to augment the volume of natural light will provide a continuous light rendition on the sculpture. The project, scheduled for completion at the end of the 2005 summer session, is at the time of this submission about 60% complete.

title	A cooperative model using semantic works dedicated to architectural design
doi	https://doi.org/10.52842/conf.caadria.2005.094

summary	Architectural cooperative design as well as information modeling have been active research areas for several decades. The use of systems adapted to the cooperative design assistance for the building domain is complex. This results from the complexity of the cooperative work (difficulties in tracking actor’s work, lack of most of the required information, coordination problems, implicit nature of most of the construction activities, etc.) The main objective of our research in these domains is to develop a tool that helps the management of a building project and aids cooperative design. So, in the first part of this article, we propose to view the exchanging data mode and cooperation tools in the building domain. The second part of this article illustrates the existing cooperative design models. Then we justify the interest shown in a new model of cooperative design where the relational organization of the project and the semantic meaning of works are taken into account. Finally, we use this new model for defining a design-aided tool, to deduce advantages and limits of the “Virtual Cooperative Project”.
