title	Holistic Building Design - An integrated building design methodology based on systems thinking for reaching sustainability
doi	https://doi.org/10.52842/conf.ecaade.2020.1.505
source	Werner, L and Koering, D (eds.), Anthropologic: Architecture and Fabrication in the cognitive age - Proceedings of the 38th eCAADe Conference - Volume 1, TU Berlin, Berlin, Germany, 16-18 September 2020, pp. 505-514
summary	This paper introduces a new perspective on methodological requirements in building design related to questions of sustainability, where stakeholders ought to look at design in an integrated way when economy, society, and technical components are embedded in an ecological holistic perspective. To bind these different aspects together and face complexity, while the goal is to reach sustainability, Holistic Building Design (HBD) is drawn on existing concepts of systems thinking (ST), integrated design processes (IDP), and application of innovative technologies through building information modeling (BIM). The main aim of this approach is to involve deeper in all aspects of sustainable building design. The methodology is introduced and empirically practiced in a master's level course, and a general overview besides the first results of this on-going process are presented in this paper. It is observed that the HBD framework could significantly influence the understanding of the design process and enhancing it by iterative decision-making and turning the focus on the early design stage.

title	Intuitive Analysis as Mediator Between Concept and Representation
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Representation in Computer Aided Architectural Design Systems has to date largely focused on the presentation of the end product of design activity, namely the ultimate built form. In thisrespect, 3-dimensional representations traditionally associated with CAAD visualization have relied heavily upon verisimilitude for their efficacy, and have therefore necessitated high levels of dimensional accuracy together with exhaustive description, both of which are absent in the early stages of design formulation. This paper investigates the desired structure of a computational design formulation system which is based, not upon the representation (or presentation) of ultimate form, but instead upon the representation of architectonic ideas resident in the designer's mind, which are central to the organization and generation of proposals. These ideas are of two kinds: conceptual generators, both poetic and architectonic, and the organizational parti or schematic proposals, which embody them. The representation of ideas rather than end form has two primaryobjectives. Firstly, it enables the designer's realization and clarification of concept or parti, and secondly, but most importantly, it enables the designer to critically assess these ideas in relation tothe contextual situation and brief. The computational representation must be structured in a manner which supports the designer's intuitive critical assessment of it, to in turn induce a modification and development of the initial design ideas. Repeated transformation, representation, and intuitive analysis, can then continue in a cyclical manner until an end proposal is achieved. Intuitive analysis, which becomes the mediator between idea and representation, is itself computationally supported by the dual methodologies of comparative and modal superimposition. Superimposition of previous with present representation (either in two or three dimensions)enhances comparative assessment of design developments. Modal analysis, on the other hand, facilitates the superimposition of schematic representations of modes of design thought (circulationpattern with volumetric arrangement, say) in order to intuitively assess their interaction or conflict.

Online and Global. 3-6 November 2021. edited by B. Bogosian, K. Dörfler, B. Farahi, J. Garcia del Castillo y López, J. Grant, V. Noel, S. Parascho, and J. Scott. 372-379.
summary	The research presented in this paper proposes a bespoke digital machine-material system for architectural assembly. The research aims to contribute to the body of work in digital material systems and single-task construction and fabrication robotics. Specifically, the system proposes a digital material system based on the icosahedral quasicrystals accompanied with a bespoke assembling robot capable of locomotion along the material as well as manipulation of discrete material units. Through a set of locomotion and pick and place routines, the robotic system is capable of construction and reconfiguration of the material system. In proposing a digital machine-material system, the presented research argues for the development of design, fabrication, and robotics strategies wherein hardware, geometry, material, and software are developed in parallel in an interdependent co-design process. Such approach of considering parameters across the spectrum of design tasks allows to develop systems that are well suited for their specified application while maintaining minimum complexity and increasing accessibility of fabrication systems.

title	XML-Based Interactive 3D Campus Map
doi	https://doi.org/10.52842/conf.caadria.2003.631
source	CAADRIA 2003 [Proceedings of the 8th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 974-9584-13-9] Bangkok Thailand 18-20 October 2003, pp. 631-640
summary	This paper presents the development of a prototype XMLbased 3D campus map using the 3D VML library. Many universities in the U.S. use two-dimensional (2D) raster image to provide the campus map along with additional building information on their Web site. Research shows that three-dimensional (3D) expression of the 3D objects helps human beings understand the spatial relationship between the objects. Some universities use 3D campus maps to help visitors more intuitively access the building information. However, these 3D campus maps are usually created using raster images. The users cannot change the view point in the 3D campus map for better understanding of the arrangement of the campus. If the users can navigate around in the 3D campus map, they may be able to locate the building of their interest more intuitively. This paper introduces emerging Web technologies that deliver 3D vector graphics on the Web browser over the internet, and the algorithm of the prototype XML-based 3D campus map. Some advantages of using VML in delivering the interactive 3D campus map are also discussed.

summary	Due to the lack of trained individuals in the construction industry and to its potential impact on construction planning, Building Information Modeling (BIM) has been one of the popular topics taught in academic institutions in the U.S. in recent years. Although it is necessary to master multiple BIM applications in order to fully employ BIM in construction, teaching college students all of these applications in one semester is challenging. This paper presents an industry - sponsored class project developed to help students learn the principles of BIM in a short time. It also presents the opportunities and challenges you may encounter in implementing this class project.

title	4D Construction Simulation Model of MASP
source	The next city - New technologies and the future of the built environment [16th International Conference CAAD Futures 2015. Sao Paulo, July 8-10, 2015. Electronic Proceedings/ ISBN 978-85-85783-53-2] Sao Paulo, Brazil, July 8-10, 2015, pp. 370-379.
summary	Building Information Modeling (BIM) is an effective tool students can use to learn how building components work together to secure necessary structural stability in the course of construction. In Summer 2014, students enrolled in the BIM class at Texas A&M University created a 4-dimensional construction simulation model of the Museu de Arte de São Paulo (MASP) to understand how the entire building is sustained by two huge concrete beams connected with four external columns. For this class project, students analyzed the building system while creating a 3-dimensional model of the museum. They also came up with a construction sequence that would best maintain structural integrity of the building in the course of construction, and then produced a short animation video explaining the MASP construction process. This paper presents how the MASP project helped students learn a unique building system and its construction sequence.

title	Electroencephalogram (EEG) based Emotional Lighting Design Using Deep-Learning for a User-Centric Approach
doi	https://doi.org/10.52842/conf.caadria.2024.3.391
source	Nicole Gardner, Christiane M. Herr, Likai Wang, Hirano Toshiki, Sumbul Ahmad Khan (eds.), ACCELERATED DESIGN - Proceedings of the 29th CAADRIA Conference, Singapore, 20-26 April 2024, Volume 3, pp. 391–400
summary	This study proposes a methodology for using artificial intelligence (AI) and biometrics in spatial design. The research mainly applies a gated recurrent unit (GRU) model, a recurrent neural network (RNN), to analyze electroencephalogram (EEG) data and dynamically adjust lighting according to the user's emotional state. This study suggests an illumination adjustment system that modifies lighting according to the user's emotional state using the proposed method. Integration of EEG data can overcome the limitations of lighting systems. It can effectively target individual emotional responses. The GRU model represents a significant improvement in lighting design by addressing both cognitive and emotional user needs. The model's effectiveness in processing real-time data and adapting through incremental learning was evaluated. The model has shown a significant impact on emotional architecture and spatial design, with a focus on individual experience.

summary	In 2018 I was invited to visit the archipelago of Kiribati, located in the Pacific Ocean around 1000 miles from Hawaii. A big ocean state, Kiribati holds a land mass of around 315 sq. miles and an oceanic economic zone of 1,328,890 sq. mi. Tarawa, the most inhabited of the islands peaks at around 3 m above sea level. I went to Kiribati in part to meet with Dr Teweiariki Teaero, a renowned scholar, poet and educator who had directed the Oceania Center at the University of the South Pacific in Fiji for many years before returning to his homeland where at the time he had been planning on running for government. Teweiariki spoke with me at length about the status of Kiribati as one of the already most critically affected frontline nations. I asked him what was a lesson for non-Pacific Islanders to learn about understanding everyday life there. He said to me “Two ears, one mouth, don’t talk too much. Learn to listen more. Not only to hear, but to be able to develop another thing and that is to be able to interpret. These things are different, they occur at different levels. The hearing and the interpretation of the sound…it’s very much part of our world” (Teaero 2018).

title	An Automatic Algorithm Designer : An Initial Implementation
source	Design Research Center, CMU, May, 1983. 10 p. includes bibliography
summary	This paper outlines a specification for an algorithm-design system (based on previous work involving protocol analysis) and describes an implementation of the specification that is a combination frame and production system. In the implementation, design occurs in two problem spaces: one about algorithms and one about the task domain. The partially worked out algorithms are represented as configurations of data-flow components. A small number of general purpose operators construct and modify the representations. These operators are adapted to different situations by instantiation and means-ends analysis rules. The data-flow space also includes symbolic and test-case execution rules that drive the component-refinement process by exposing both problems and opportunities. A domain space about geometric images supports test-case execution, domain-specific problem solving, recognition and discovery

title	A Knowledge-Based Approach to Using Efficiency Estimation in Program Synthesis
source	1980? pp. 457-462. includes bibliography
summary	This paper describes a system for using efficiency knowledge in program synthesis. The system, called LIBRA, uses a combination of knowledge-based rules and algebraic cost estimates to compare potential program implementations. Efficiency knowledge is used to control the selection of algorithm and data structure implementations and the application of optimizing transformations. Prototypes of programming constructs and of cost estimation techniques are used to simplify the efficiency analysis process and to assist in the acquisition of efficiency knowledge associated with new coding knowledge. LIBRA has been used to guide the selection of implementations for several programs that classify, retrieve information, sort, and generate prime numbers

title	Parallel Processing Techniques for Hidden Surface Removal
source	SIGGRAPH '79 Conference Proceedings. 1979. vol. 13 ; no. 2: pp. 300-307 : ill. includes bibliography
summary	Previous work in the hidden-surface problem has revealed two key concepts. First, the removal of non-visible surfaces is essentially a sorting problem. Second, some form of coherence is essential for the efficient solution of this problem. In order to provide real-time simulations, it is not only the amount of sorting which must be reduced, but the total time required for computation. One potentially economic strategy to attain this goal is the use of parallel processor systems. This approach implies that the computational time will no longer be dependent on the total amount of sorting, but more on the appropriate division of responsibility. This paper investigates two existing algorithmic approaches to the hidden-surface problem with a view towards their applicability to implementation on a parallel machine organization. In particular, the statistical results of a parallel processor implementation indicate the difficulties stemming from a loss of coherence and imply potentially important design criteria for a parallel configuration

title	Where No Mind Has Gone Before: Ontological Design for Virtual Spaces Papers
source	Proceedings of the ECHT'94 European Conference on Hypermedia Technologies 1994 pp. 206-216
summary	Hypermedia designers have tried to move beyond the directed graph concept, which defines hypermedia structures as aggregations of nodes and links. A substantial body of work attempts to describe hypertexts in terms of extended or global spaces. According to this approach, nodes and links acquire meaning in relation to the space in which they are deployed. Some theory of space thus becomes essential for any advance in hypermedia design; but the type of space implied by electronic information systems, from hyperdocuments to "consensual hallucinations," requires careful analysis. Familiar metaphors drawn from physics, architecture, and everyday experience have only limited descriptive or explanatory value for this type of space. As theorists of virtual reality point out, new information systems demand an internal rather than an external perspective. This shift demands a more sophisticated approach to hypermedia space, one that accounts both for stable design properties (architectonic space) and for unforeseen outcomes, or what Winograd and Flores call "breakdowns." Following Wexelblat in cyberspace theory and Dillon, McKnight, and Richardson in hypermedia theory, we call the domain of these outcomes semantic space. In two thought experiments, or brief exercises in interface design, we attempt to reconcile these divergent notions of space within the conceptual system of hypermedia.

source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 2, pp. 793-798
summary	This paper describes the theoretical and technological parameters for a digital interface, in development by MOM/LOW (Morar de Outras Maneiras/ Living in Other Ways), intended at the autonomous production of dwelling. It introduces the current formal and informal processes of production of dwelling arguing for the need of an instrument to enable both the distribution of alternative building components and user participation. It discusses the main questions on agency and machine intelligence as to show the need to take human-machine asymmetry into account in interface design. It also points out the main problems regarding the current technology for creating 3D digital interactive interfaces, and indicates one possible way to use the available technology and locate agency in the event. It concludes by showing that interface design can take advantage of human dialogical ability and of the machine’s capacity to offer material for that dialogue, without humanising the machine or preconditioning human responses.

title	Shading: fitting a smooth intensity surface
source	Computer-Aided Design, Vol. 27 (8) (1995) pp. 595-603
summary	Visual realism in computer-generated images is an important goal for many computer applications. However, a tradeoff exists between the degree of realism achieved and thetime required to generate an image. Thus efficient algorithms for generating realistic images are being actively investigated.Shading is one graphical technique for rendering more realistic images of 3D objects. However, the most widely used algorithm, Gouraud shading, suffers from the Machband effect, a perceptual phenomenon that reduces realism. Gouraud shading also handles specular reflection poorly. The next most popular algorithm, Phong shading,generally reduces Mach banding and captures specular highlights, though at great computational expense. Bishop and Weimer improved the efficiency of Phong shading, buttheir algorithm introduces approximation error and is still significantly slower than Gouraud shading.A new algorithm is proposed which takes an innovative approach to shading 3D objects. A smooth intensity surface is generated with a known surface-fitting technique,Powell-Sabin quadratic interpolation. The intensity surface is generated at a modest cost using the Cendes-Wong formulae and forward differencing. The C1 surface virtuallyeliminates Mach banding.

source	Hybrid Spaces of the Metaverse - Architecture in the Age of the Metaverse: Opportunities and Potentials [10th ASCAAD Conference Proceedings] Debbieh (Lebanon) [Virtual Conference] 12-13 October 2022, pp. 301-312
summary	To represent design, both physical and digital models are utilized in the process. However, they usually don't function in unison. In order to synchronize these two types of models, the changes made in one model are generally translated into the other one later. This study intends to provide a conceptual framework for a simultaneous and synchronized model for the use of material, structure, and performance in the preliminary design stage. The methodology of the study includes evaluating material attributes, structural systems, and building performance of a physical model in the digital environment by using a Mobile Augmented Reality (MAR) interface. Because the cameras in MAR environment are mobile, the range of views can be expanded, and/or designs can be superimposed on user interfaces virtually. Thus, object interaction and navigation are all made possible. By offering a comprehensive, synchronized, and interactive design environment, where material, structure, and performance factors are incorporated both in physical and digital models, the suggested methodology will potentially aid users' decision-making process.

summary	This paper focuses on using a game approach on archeological heritage sites and possibilities for using a location-based game for spatial knowledge acquisition through game space. We propose a location-based game design and a research strategy to decode the spatial information acquisition in the archaeological site sample through user behaviors and cognitive map representations in both spaces (the physical and game space). Our research, part of an ongoing study, presents user experiments’ results conducted on the Kültepe Kanesh Karum, Kayseri archeological site, including two setups (sightseeing and game experience) with four participants for each. The collected data includes user traces in the environmental setting using GPS tracking and user experience feedback of sketch map drawings and expressions. Collected data encoded with the spatial legibility parameters (road, node, and landmarks) and interpreted separately and comparatively for both experimental groups. Our initial results indicate the potential of the game space and its effect on acquiring spatial knowledge.
