title	Typological Knowledge in Computer-Aided Housing Design -- Chapter 6
source	Helsinki, Finland: the Finish Academy of Technology, 1989. No. 92: pp. 49-60 : ill. includes bibliography
summary	This paper considers logical aspects in the knowledge and rule based approach to housing planning and design. The generation problem in housing design is formulated and some experimental work in the field is discussed. Logical methods in knowledge-based generation are introduced as a frame for various production situation. Formation of typical compositions is discussed as a basis for more advanced design. Generation of typological classes and mastering of individual solutions by means of sets of predicates are used to form knowledge-bases for elementary housing solutions. The possibilities of sentenial calculi are characterized in order to allow reconstruction of tradition-guided expert know how. Finally some desirable characteristics of computer aided housing design systems are illustrated

title	Bio-shell (biodegradable vacuum-formed modularised shelter)
doi	https://doi.org/10.52842/conf.caadria.2010.565
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 565-574
summary	This paper demonstrates how digitally fabricated vacuum-formed components can provide a new type of efficient construction applicable to architecture. Vacuum forming has the advantage of rapid mass-production capability of 3D curved forms. Recent digital fabrication technologies, such as 3D CAD and CNC machining, have dramatically reduced the cost and time for making the mould. In combination with biodegradable plastic, such as PLA (poly lactic acid) made of biopolymer, it could open up new type of sustainable construction system, which is applicable for temporal disaster housings or exhibition booths.

title	Equalizing Daylight Distribution: Digital simulation and fabrication of optimized inner reflectors and bottom extractors for a light-duct
doi	https://doi.org/10.52842/conf.ecaade.2012.1.607
source	Achten, Henri; Pavlicek, Jiri; Hulin, Jaroslav; Matejovska, Dana (eds.), Digital Physicality - Proceedings of the 30th eCAADe Conference - Volume 1 / ISBN 978-9-4912070-2-0, Czech Technical University in Prague, Faculty of Architecture (Czech Republic) 12-14 September 2012, pp. 607-612.
summary	The present paper explores the implementation of a light-duct in order to equalise daylight distribution in an office space. While the illuminance level near windows in a building tends to be higher than that necessary for the working environment, artificial lighting is often used to ensure that the workspace further away from the windows has the required level of illuminance. Equalising daylight distribution from the periphery to the inner part would thus provide signifi cant advantages for energy-efficient lighting as well as the fl exible and efficient use of offi ce space. In order to achieve this goal, anti-glare devices in the perimeter zone such as louvers and daylight distribution devices such as light-ducts are required. In this paper, we focus on light-ducts in the first instance, with an emphasis on their two key components for controlling the direction of daylight, namely inner reflectors and bottom extractors.

summary	Expanded Polystyrene foam (EPS) is a chemically inert and 100% recyclable material that is lightweight and has a good compression strength per weight ratio; however, its current construction use is mostly limited to insulation or landfill. The key concept of this paper is to develop an EPS composite to create an ultra-lightweight long-span sustainable roofing structure by integrating the minimum necessary structural tension layer with a certified fire protection system. The authors present this concept in the following four steps, 1) EPS composite structural specimen test, 2) structural optimisation of the reversed displacement model, 3) discretisation with developable surfaces and 4) CNC hotwire rapid prototyping and assembly in scaled prototypes. The Cloud Arch is an economical, material-efficient, thermally insulated, quickly assembled ultra-lightweight construction that eliminates the need for formworks for long-span structures. It can be applied to many types of column-free spaces, such as in factories, gymnasiums, markets and cafeterias.

title	Groove Light - Adding Physical Reality to Virtual Projections Using 3D-printed Lanterns
doi	https://doi.org/10.52842/conf.ecaade.2016.1.113
source	Herneoja, Aulikki; Toni Österlund and Piia Markkanen (eds.), Complexity & Simplicity - Proceedings of the 34th eCAADe Conference - Volume 1, University of Oulu, Oulu, Finland, 22-26 August 2016, pp. 113-120
summary	How might 21st-century computational technologies enhance lighting functionality in architecture? The Groove Light provokes relationships between light and shadow, adding a new dimension to future lighting. A series of distinctive and complex 3D-printed lanterns, which cast identical patterns of geometric shadows, creates the optical illusion that they are floating above a continuous, geometric carpet of shadows. The authors tested this concept in three steps: 1. 3D printability, 2. a lighting test and 3. interactivity. The paper also reports the effectiveness of a selective and custom support strategy for printing overhanging geometries with fused deposition modelling (FDM) 3D printers and further highlights differences between the computational models and physical prototypes in the quest for 'point' light sources.

title	Bio-shell (Biodegradable vacuum-formed modularized shelter)
source	T. Tidafi and T. Dorta (eds) Joining Languages Cultures and Visions: CAADFutures 2009 CD-Rom
summary	This poster demonstrates how digitally fabricated vacuum-formed components can provide a new type of lightweight construction applicable to architecture. Surface-active systems such as a thin-shell concrete domes are some of the most material-efficient structures. Despite their efficiency few have been constructed recently due to necessary extensive labor cost. However, the growing concern for a worldwide shortage of natural resources and rising material costs, suggests that we reconsider the use of efficient structures, such as surface-active systems. Vacuum formed plastics mainly used in industrial design have strong merit based on their fast and low-cost mass production. Together with the recent emergence of digital fabrication technologies, the vacuum forming process is becoming an attractive fabrication technique for new and innovative lightweight structures.

source	SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary	This work explores the Geometric Modeling possibilities as a tool for professional use to the Furniture Design by Interior Architecture professionals. It is considered that the modeling process contributes to the characterization of furniture, since it is necessary the definition of the geometric procedures to generate and control the represented form. Searching for evidences of the kind of contribution, some experiments were developed using chairs from different periods as the object for representation. Three chairs were selected to model, from three different historical periods. The modeling processes were based on the use of 3D Studio Max, registered, analyzed and compared. The results defined references to the use of Digital Graphics to support the representation and also to studies of the furniture form.

title	CREASE: Synchronous gait by minimizing actuation through folded geometry
source	International Journal of Architectural Computing vol. 18 - no. 4, 385–403
summary	The Age of the Fourth Industrial Revolution promises the integration and synergy of disciplines to arrive at meaningful and comprehensive solutions. As computation and fabrication methods become pervasive, they present platforms for communication. Value exists in diverse disciplines bringing their approach to a common conversation, proposing demands, and potentials in response to entrenched challenges. Robotics has expanded recently as computational analysis, and digital fabrication methods are more accurate and reliable. Advances in functional microelectromechanical components have resulted in the design of new robots presenting alternatives to traditional ambulatory robots. However, most examples are the result of intense computational analysis necessitating engineering expertise and specialized manufacturing. Accessible fabrication methods like laminate techniques propose alternatives to new robot morphologies. However, most examples remain overly actuated without harnessing the full potential of folds for locomotion. Our research explores the connection between origami structures and kinematics for the generation of an ambulatory robot presenting efficient, controlled, and graceful gait with minimal use of components. Our robot ‘Crease’ achieves complex gait by harnessing kinematic origami chains rather than relying on motors. Minimal actuation activates the folds to produce variations in walk and direction. Integrating a physical iterative process with computational analysis, several prototypes were generated at different scales, including untethered ones with sensing and steering that could map their environment. Furthering the dialogue between disciplines, this research contributes not only to the field of robotics but also architectural design, where efficiency, adjustability, and ease of fabrication are critical in designing kinetic elements.

title	An Experiment at the Smart Campus UEL: Guidelines for a Technological Tool of Architectural Heritage’s Visual Perception
source	Herrera, PC, Dreifuss-Serrano, C, Gómez, P, Arris-Calderon, LF, Critical Appropriations - Proceedings of the XXVI Conference of the Iberoamerican Society of Digital Graphics (SIGraDi 2022), Universidad Peruana de Ciencias Aplicadas, Lima, 7-11 November 2022 , pp. 1089–1100
summary	This research aims to think of guidelines, from a Smart Heritage perspective, for the development of an artifact that will aim to “boost” the visual perception of the architectural heritage. Thus, the Smart Campus at UEL works as the research environment, as a living lab to test the points of the Smart City. The research was designed in Design Science Research in six steps: (1) Problem Identification, (2) Suggestion, (3) Development, (4) Demonstration, (5) Evaluation, and (6) Communication. The results presented correspond to phases (1), (2) and structuring of (3). Step (2) had a focus group of four experts in the field of architectural heritage and sought a more realistic epistemological position, focusing on real problems and solutions about the visual perception of architectural heritage in visitation itineraries. Based on the experts' statements, a cross-check was made with the points raised in the Smart Heritage literature to then list the main guidelines for the artifact.

summary	The graduation course of Architecture and Urbanism of the Federal University of Santa Catarina makes use of informatic tecnology in several teaching and research activities. This technology supports initial data proccessing, analysis, evaluations, simulations, and project development both in architecture and urban fields. Aiming to stimulate and improve the use of computer techniques in graduation courses, the INFOARQ group, belonging to the 'LABMICRO' developed the project 'Digital Floripa'. This project is an CD image data basis, with digital aerophotographs Florianópolis’ city taken, from the aerophotogrametric data of 1994. This project aims to facilitate image's access to teachers, students and researchers, to allow use of photos and scales, and to make possible the development of new alternatives interventions. A navegator program called 'DIGITAL INDEX'supports the user in the image's search and creates a same graphic interface. This project also acts as basis for research development wich aims to analyse and develop tutorial proceedures to access the utilization of the data images basis.

title	Collaborative or adversarial production and BIM: a method for better understanding of contracting types, based on BPMN
source	SIGraDi 2018 [Proceedings of the 22nd Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Brazil, São Carlos 7 - 9 November 2018, pp. 581-589
summary	BIM represents a paradigm change in the production process, and its use can be facilitated or hindered by the contracting scheme. Contracting can be relational or transactional; the first refers to collaboration and the second to an adversarial environment. In literature, the different contracting schemes are presented in textual form, which is not the best format to analyze similarities and differences among them. A graphical form for comparison is proposed, using the well-known diagrams of AIA and the BPMN notation. A collaborative production process favors integration and the use of BIM, resulting in more efficiency and quality of the project.

summary	Over the past decade, ‘smart’ cities have capitalized on new technologies and insights to transform their systems, operations and services. The rationale behind the use of these technologies is that an evidence-based, analytical approach to decision-making will lead to more robust and sustainable outcomes. However, harvesting high-quality data from the dense network of sensors embedded in the urban infrastructure, and combining this data with social network data, poses many challenges. In this paper, we investigate the use of an intelligent middleware – Device Nimbus – to support data capture and analysis techniques to inform urban planning and design. We report results from a ‘Living Campus’ experiment at the University of Melbourne, Australia focused on a public learning space case study. Local perspectives, collected via crowdsourcing, are combined with distributed and heterogeneous environmental sensor data. Our analysis shows that Device Nimbus’ data integration and intelligent modules provide high-quality support for decision-making and planning.

source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The evolution of the graphical representation of the architecture with the development of procedures for computer-aided designs is causing a shift in the way of thinking about architecture. Traditionally, the teaching of descriptive geometry that allows architects in training cognition full three-dimensional space. Changing this tradition, today we have the construction of the projective drawing by computer, CAD or BIM. We aim to question the way to teach courses in the projective geometry of architecture and urbanism in the face of profound changes in knowledge and representation of the form established by computer graphics technology with CAD and BIM.

title	An information technology forecast for the architectural profession
source	Automation in Construction 4 (4) (1996) pp. 263-279
summary	Much of our research in IT in construction is concerned with developing technologies and prescribing how they can be applied to construction problems. Our rationale for our choice of technologies to push is often unstated and the relative significance of a range of technologies is rarely considered. The impact of emerging technologies on the strategic health of companies and professions is also rarely discussed. Few professions appear to be explicitly in control of how IT will impact their future.This paper addresses both of these issues through the example of an IT forecast for the architectural profession. It does this by examining issues of technology forecasting and development by reviewing currently emerging IT's and by conducting an opinion survey of which are of greatest significance to the architectural profession. The result is a relative assessment of the importance to architects of 10 technological mini-scenarios from which an overall architectural IT scenario is constructed.

source	SIGraDi 2011 [Proceedings of the 15th Iberoamerican Congress of Digital Graphics] Argentina - Santa Fe 16-18 November 2011, pp. 476-479
summary	The Space Syntax Theory (SST) has been taught at the Bartlett School of Postgraduate Studies at UCL as a tool for architects to explore the relationship between spatial configuration and social form. It has also been used as a design tool to explore and understand, during the design process, possible effects of design ideas on people interaction with space. However the introduction of SST in the first stage of architectural training as a learning resource for developing spatial configuration abilities has not been explored in detail yet. This paper is going to discuss an experience of training architectural students using the SST.

title	Training Programs for Art and Design Learning in the Virtual Studio
doi	https://doi.org/10.52842/conf.ecaade.2007.639
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 639-646
summary	Computers are very common drawing tools at university design studios but their potential as training tools in arts and design has not been explored in depth. In arts and design the learning process is based on ‘knowing in action’ (Schön 1983). Therefore, training is the keystone of the learning process in arts and design. This action takes the form of a reflective practice based on the manipulation of a media where each media has its own possibilities, its own limits in communicating design ideas or artistic concepts. With the introduction of digital media in the design studio, it is expected that reflective practices in design learning will experience a qualitative change. However, currently there is little understanding of how to use the digital and virtual media in a design studio as a learning tool (Szalapaj 2001), nor of the use of design training programs. In this paper the use of training programs in an experimental design course at a university level, is discussed. This experience was carried out as a PhD research experiment at the Faculty of Architecture and Arts of the Universidad de Los Andes in Merida, Venezuela. The training programs discussed here were designed for an eight week introductory design course in a virtual design studio. The programs were written in VRML and conceived as a virtual design training environment. Each program was designed for a specific design exercise, based on a learning strategy and an interactivity model proposed for object manipulation in design training. A comparative analysis of the data gathered from the course was made of training exercises done with a Cad program and with the training programs and crossing information with other sources. The experiment shows that the training programs, their learning strategy and the interactivity model proposed were successful in guiding the scope of the design exercises during the training process.
