title	Learning in the living campus - remotely sensing activities correlated to learning in outdoor spaces
source	SIGRADI 2015 [Proceedings of the 19th Conference of the Iberoamerican Society of Digital Graphics - vol. 2 - ISBN: 978-85-8039-133-6] Florianópolis, SC, Brasil 23-27 November 2015, pp. 589-595.
summary	This paper presents preliminary results of a research that seeks to develop an algorithmic model to represent how campus users interact with one another, as well with the surrounding environment, in order to comprehend the dynamics of activities that can be correlated to learning in open spaces and thus develop design guidance for such spaces. The hypothesis is that learning activities in outdoor spaces is also responsible to contribute to the life of the academic purpose of the campus, and that this can then inform design decisions for such spaces to better support outdoor informal learning. During the research, video recording and interviews were used to collect data and identify patterns of behavior in three research sites in the University of Melbourne.

title	Gramáticas da forma e modelagem paramétrica – uma aplicação na área da arquitetura paisagística [Shape grammars and parametric modeling – an application in the field of landscape design]
source	SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 397-400
summary	The objective of the present paper is to propose a design solution database to help students learn basic landscape design concepts and help them apply this new knowledge by using examples developed by an experienced designer. The system is based on an ontology that contains classes of design concepts and design instances. Beyond the structure to search for design concepts and precedents, it’s also proposed an interactive module implemented in a parametric design tool. This module allows students generate and insert automatically different parametric components, such as a group of trees, bushes, sculptures, in a digital model. The system efficacy was verified in a workshop performed with undergraduate students.

title	Análisis del Comportamiento Lumínico en Edificios mediante Herramientas Digitales (Analysis of the lighting Behavior in Buildings by means of Digital Tools)
source	SIGraDi 2003 - [Proceedings of the 7th Iberoamerican Congress of Digital Graphics] Rosario Argentina 5-7 november 2003
summary	In temperate humid climates, like Rosario city, (33 S, 60 W), in which heating and cooling loads are required seasonally, daylighting and artificial lighting optimization, under an energy saving basis are essential issues for designers. Energy reduction in buildings permits lower functioning costs, better maintenance, and overall economy. Electricity consumption in offices has increased in the latest years due to an intensive use of artificial lighting and new appliances (computers, printers). This equipment also generates heat which must be eliminated, increasing further energy consumption. This paper focuses on spaces assessment and adjustment through digital tools aid, so as to evaluate strategies of interior lighting performance.

title	Teaching/learning Architectural Design based on a Virtual Learning Environment
source	International Journal of Architectural Computing vol. 7 - no. 2, 255-266
summary	This paper describes an experiment in which a virtual learning environment was used in the context of an architectural design course. The objective was to evaluate the capability of the learning environment used to support the interactions needed, between teacher-student and between students, for the establishment of a process of discussion and development of architectural design. Some limitations were identified and also positive points, such as the possibility to register the whole design process. These registers allow the design teacher to evaluate his own teaching process and improve it and also the visualization of what kind of intervention the teacher makes and when, making it possible to identify the kind of design processes established by the student and the kind of structure of knowledge which is implicit in a process of teaching/learning architectural design according to the level of development of the design.

title	Line Drawings of Octree- Represented Objects
source	ACM Transactions on Graphicsò January, 1988. vol. 7: pp. 61-75 : ill. includes bibliography.
summary	The octree structure represents the space occupied by an object as a juxtaposition of cubes. The octree structure is highly sensitive to object location and orientation, and the three-dimensional shape of the represented object is obscured. It is helpful to be able to see the actual object represented by an octree, especially for visual performance evaluation of octree algorithms. This paper presents a display algorithm that helps visualize the three-dimensional space represented by the octree. Given an octree, the algorithm produces a line drawing of the object represented by the octree, using parallel projection, from any specified viewpoint with hidden lines removed. Example of some line drawing produced by the algorithm are given. The complexity of the algorithm is also discussed

title	Towards computer-supported inclusion and integration of life cycle processes in product conceptualization based on the process tree
source	Automation in Construction 10 (6) (2001) pp. 731-740
summary	Development of computer support in design is showing several shifts in focus over the latest decades. This paper relates to the shifts from detail design to conceptualization, from artifact geometry definition only to the inclusion of process knowledge, and from isolated aspects to integrated aspects. It discusses a possible solution for simultaneous consideration of life cycle process aspects during conceptual design using the process tree representation. Integrating process aspects can be considered a preparation for an integrated representation of artifact and process aspects to be used in a front–end environment for conventional CAD detailing systems

title	Hybrid Experience Space for Cultural Heritage Communication
doi	https://doi.org/10.52842/conf.ecaade.2006.022
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 22-30
summary	Cultural heritage institutions like the museums are challenged in the global experience society. On the one hand it is more important than ever to offer “authentic” and geographically rooted experiences at sites of historic glory and on the other hand the audience’s expectations are biased by daily use of experience products like computer-games, IMAX cinemas and theme parks featuring virtual reality installations. “It’s a question of stone-axe displays versus Disney-power installations” as one of the involved museum professionals point it, “but we don’t want any of these possibilities”. The paper presents an actual experience design case in Zea Harbour, Greece dealing with these challenges using hybrid experience space communicating cultural heritage material. Archaeological findings, physical reconstructions and digital models are mixed to effectively stage the interactive experience space. The Zea Case is a design scenario for the Museum of the Future showing how Cultural Heritage institutions can reinvent the relation to the visitor and the neighbourhood. While Hybrid Experience Space can be used for Cultural Heritage Communication in traditional exhibitions we have reached for the full potential of on-site deployment as a hybrid experience layer using Google Earth and mobile technology.

summary	Facades have great impact in a house´s performance being directly linked to energetic consumption and comfort. Computing sciences propose the systematization of design processes, making it possible to determine an optimal configuration for a tropical building, in order to get a desired comfort performance, based on the implementation of parametric design and artificial intelligence. This research seeks sustainable design by implementing design guidelines, geometrical parameterization and its further optimization. Now it is possible from early stages of design to provide results that can benefit people generating comfort conditions.

title	Concrete Construction for Social Housing in Colombia: Towards a higher productivity supported by the use of Digital tools and off-site processes.
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. 569–580
summary	This paper presents the outcomes of a collaborative project between UK and Colombian researchers, aimed at increasing productivity and lowering emissions for the construction of social housing in Colombia, particularly when using concrete as the main building material. Based on the findings of a previous project that focused on the automation of concrete construction within the UK context, and following the implementation of interviews with local industry experts, the researchers analyzed the opportunities and challenges of incorporating digital technologies in order to improve the construction process, and found out that there was higher potential in the design and management areas rather than in the actual production of components, where standard prefabrication was perceived as the most fitting solution. This paper will introduce some of the advances in the project, which include a diagnosis of the challenges and obstacles of prefabricated systems used in construction, obtained from interviews with leaders and actors in the sector, a meta-analysis of barriers and opportunities of the use of concrete prefabrication in other contexts, the development of a typology as an example of an application developed as part of the project development, and finally a software tool to support the proposed case of application.

title	Improving Buildability of Overhangs of 3D Printed Objects Through Non-Planar Slicing Informed by Force Flow Analysis
doi	https://doi.org/10.52842/conf.ecaade.2023.1.519
source	Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 1, Graz, 20-22 September 2023, pp. 519–526
summary	The traditional method of data preparation for 3D printing, known as planar slicing, involves slicing the 3D model into horizontal layers and printing them gradually. This is the simplest option with the main parameter being layer height. However, this method has several limitations, including poor surface finish with stair-stepping contours of layers at steep angles and a necessity to print additional support structure for overhangs. Non-planar slicing is a newer method that involves slicing the 3D model into non-horizontal layers with varying layer heights. This technique is mostly explored in plastics, with observed improvements in buildability, surface finish and reduction of cracking alongside the layers. In construction scale, non-planar printing is used primarily for achieving unique surface finish, or for printing on an uneven base. Its potential for improving buildability is still yet to be properly tested. This paper examines how non-planar layers can be derived with a help of force flow lines and how it affects the buildability. While printing overhangs, shear force can ultimately break the interlayer bond and layers can start deforming and sliding on top of each other, resulting in buckling, or even collapse. By guiding these forces into the bulk of layers instead of interlayer bonds, printing capabilities can be improved. Goal of this paper is to present how buildability of overhangs can be improved using non-planar slicing. Non-planar layers are derived from force flow line simulations done in Karamba3D. For printing we use clay, as a fast and simple prototyping method with the aim to later utilise our findings into concrete printing.

title	Enhancing 3D Concrete Printing Buildability with Non-Planar Layering
doi	https://doi.org/10.52842/conf.ecaade.2024.1.175
source	Kontovourkis, O, Phocas, MC and Wurzer, G (eds.), Data-Driven Intelligence - Proceedings of the 42nd Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2024), Nicosia, 11-13 September 2024, Volume 1, pp. 175–182
summary	This paper explores improvements in 3D Concrete Printing (3DCP) buildability using non-planar layering. Our proof-of-concept experiment validates the assumption that non-planar layering enhances the buildability of overhangs and vaults. To test this, we designed an object comprising two columns with a Gothic arch and overhangs on the upper part, resulting in a continuous wall at the top. The object measures approximately 1.5 meters in length, 400 mm in width, and 700 mm in height. The design was executed to maintain the centre of mass in the centres of the columns across all print layers, mitigating unwanted deformation. The overhang angle ranged continuously from 0 to 70 degrees. The object was modelled in Rhinoceros software, and G-code for both planar and non-planar printing was generated in Grasshopper. Both samples were designed to use the same amount of material, print length, and print time. We printed these using a cementitious mixture with plastic fibres and an additional accelerant mixed in the nozzle on a gantry printer. Throughout the printing process, we conducted careful observation and monitoring to detect any instances of buckling or collapse. Post-print measurements were carried out to evaluate the deformation of the printed objects, revealing a reduction in deformation with non-planar printing. This paper discusses the analysis of results and proposes a workflow for future data preparation for non-planar slicing.

title	Computational and Physical Modeling for Multi-Cellular Pneumatic Envelope Assemblies
source	International Journal of Architectural Computing vol. 13 - no. 2, 143-169
summary	This article describes recent research on the performative, formal and aesthetic potentials of multicellular pneumatic foil-based envelope systems for lightweight, responsive building skins able to control thermal insulation and air exchange with minimal amounts of energy and mechanical components. The prototype-based research involves the use of principles from biological examples of pneus, which inform the design of physical analogue models at an architectural scale. The process entails physical-computational feedback loops wherein physical performance findings are fed into computational design models for pneumatics and membranes, as well as modified energy models, in order to advance the predictive design capacities of simulation tools in designing such systems. In this process, material agency allies with computational agency to develop novel possibilities for dynamic pneumatic envelopes.

summary	Mass customization is one of the most promising computational developments in the AEC industry. Despite recent advances in the production of research-based knowledge, the professional practices lack of a consistent and permanent technology adoption scheme and remain as a very resilient and fragmented industry. This work is a part of an ongoing research project developing guidelines for improving both physical and virtual modeling processes within an architectural design context. Here, we present a customizable model of a space layout explorer. The implementation of the user-driven solution-finding process is based on constraint technology embedded in Autodesk’s Revit® 2011 macros tools, commonly used in the professional practice. The aim of this work is to demonstrate a practical use of a small constraint-based system on software of widespread use. Even though there is still a lack of building information, the model has already several applications in the definition a floor plan layout and in the comparison of several instances of the design solution in the 3D user view. User-driven modifications are not made directly through the 3D model, but through different explicit text tags that describe each parameter on 2D views -although a real time 3D visualization of the model is also available-. The main findings are discussed as guidelines for further research on the end-user involvement on a ‘creative mass customization’ scheme. Also, the implementation of visual aids such as text tags during the customization process can bridge some technical obstacles for the development of interfaces for constraint-based mass customization systems. Before the final discussion, some limitations on the use of this model are described.

summary	The Abeille flat vault, patented at the end of 17th century, consists of identical ashlars arranged in a woven-like pattern that generates their interlocking mutual support. In recent years, the availability of digital design and fabrication tools has caused new interest in the Abeille vault. Several studies investigate the interlocking principles through their application onto non-planar assemblies. This paper is a is a more systematic exploration into the underlying geometric interdependencies behind interlocking principles. It approaches the Abeille vault as a topological interlocking assembly (TIA), an assembly where basic identical elements of a special shape are arranged in such a way that the whole structure can be held together by boundary constraint, while locally the elements are kept in place by kinematic constrains imposed through the shape and mutual arrangement of the elements. The paper looks at the full potential of the Abeille vault application and studies the relation between the surface geometry and TIA

title	Rationale-Supported Mixed-Initiative Case-Based Planning
source	Proceedings of IAAI-97
summary	Mixed initiative planning envisions a framework in which automated and human planners interact to jointly construct plans that satisfy specific objectives. In this paper, we report on our work engineering a robust mixedinitiative planning system. Human planners rely strongly on past planning experience to generate new plans. ForMAT is a casebased system that supports human planning through the accumulation of userbuilt plans, querydriven browsing of past plans, and several plan functionality analysis primitives. Prodigy/Analogy is an automated AI planner that combines generative and casebased planning. Stored plans are annotated with plan rationale and reuse involves adaptation driven by this rationale. Our system, MICBP, integrates ForMAT and Prodigy/Analogy into a realtime messagepassing mixedinitiative planning system. The main technical approach consists of allowing the user to specify and link objectives that enable the system to capture and reuse plan rationale. We present MICBP and its concrete application to the domain of military force deployment planning. This synergistic system increases the planning efficiency of human planners through automated suggestion of similar past plans and plausible plan modifications.

title	Cybernetic diagrams: design strategies for an open game
source	International Journal of Architectural Computing vol. 12 - no. 4, 379-398
summary	This paper investigates the use of diagrams related to cybernetics and information theory in experimental design practices in the 1960s and 1970s.Those diagrams are investigated in light of Vile_m Flusser’s concept of game, which mediates the modus operandi of computers and possible strategies for design based on distributed cognition.The research adopts the interpretative method to analyze the diagram proposed by cyberneticist Gordon Pask for Fun Palace, the diagrams produced by utopian architect Yona Friedman in the conceptual description of the Flatwriter program and Christopher Alexander’s diagrams for his theories of Synthesis of Form and Pattern Language. In the end, it establishes a brief parallel between current debates of computational design with the cybernetic diagrams, highlighting differences in their approach to complexity and design knowledge.

summary	This article investigates the notion of an augmented architectural design culture elapsed of the digital revolution. Based on analytical categories proposed by the philosopher VilémFlusser it compares two systems of creative production (the tool-architect and the robot-architect), establishing new perspectives on the architectural design supported by computers. Thereafter, it identifies in the digital design agenda the overvaluation of the generative techniques over the psycho-physiological capacity of man. Lastly, the article discusses Flusser's theories to present the risks and limitations of a design practice determined by the digital techniques.
