title	Seamfully Connected: Real Working Models as Tangible Interfaces for Architectural Design
source	Global Design and Local Materialization[Proceedings of the 15th International Conference on Computer Aided Architectural Design Futures / ISBN 978-3-642-38973-3] Shanghai, China, July 3-5, 2013, pp. 210-221.
summary	This paper describes work conducted as part of an interdisciplinary research project into new approaches to using computer technology in the early phases of the architectural design process. The aim is to reduce the existing discrepancy between familiar, analogue ways of working in the early design stages and the increasingly widespread use of digital tools in office practice. Taking this as its starting point, a prototype for a design platform was developed. The core of the project is a direct, real-time connection between real volumetric models, an interactive 3D sketching-tool and interactive digital content that supports the design process. The conceptual and technical core of this connection is an integrated object recognition system. In this paper we describe the need for an integrated solution, the underlying conceptual idea and the recognition methods implemented including their respective strengths and limitations.

title	Computing Level of Privacy in a Virtual Environment
source	International Journal of Architectural Computing vol. 11 - no. 1, 65-86
summary	This paper presents a computational model designed to analyze architectural space and to a develop privacy level using two methods: visual distance method and viewing angle method as those are primary cognitive mechanism to experience architectural space.We suggest that the result will offer possibilities for quantitative design analysis of privacy that influenced by architectural elements.The proposed method consists of two stages: determination of subdivided enclosed spaces and measuring privacy level on each subdivided enclosed space. Previous models showed that spatial quality is related to the visual distance to the architectural elements. In addition to distance variables, our model includes viewing angle variables to determine area and the direction angle from any observation point to the architectural elements on the boundary of an interior space.The case study evaluation is able to rank the quality of design of interior spaces with respect to their privacy level.

summary	Designers interested in applying evo-devo-design methods for performance based multi-objective design exploration have typically faced two main hurdles: it’s too hard and too slow. An evo-devo-design method is proposed that effectively overcomes the hurdles of skill and speed by leveraging two key technologies: computational workflows and cloud computing. In order to tackle the skills hurdle, Workflow Systems are used that allow users to define computational workflows using visual programming techniques. In order to tackle the speed hurdle, cloud computing infrastructures are used in order to allow the evolutionary process to be parallelized. We refer to the proposed method as Evo-Devo In The Sky (EDITS). This paper gives an overview of both the EDITS method and the implementation of a software environment supporting the EDITS method. Finally, a case-study is presented of the application of the EDITS method.

summary	This paper presents a visibility analysis tool for 3D urban environments and its possible applications for urban design practice. Literature exists for performing visibility analysis using various methods and techniques, however, tools that result from such research are generally not suitable for use by designers in practice. Our visibility analysis tool resides in Grasshopper, Rhino. It uses a ray casting method to analyze the visibility of façade surfaces from a given vantage point, and of a given urban setting, in particular, buildings and roads. The latter analysis provides information on the best visible buildings/building facades from segments of roads. We established a collaboration with a practicing architect to work on a design competition together, using this tool. The paper elaborates on the visibility analysis methods, presents the tool in detail, discusses the results of our joint work on the competition, and briefly reflects on the evaluation of the use of the tool by design practitioners.

title	Building Elements Re-usability Optimization - Design Decision Support Using a Case-Base of Building Information Models and Semantic Fingerprints
source	Global Design and Local Materialization[Proceedings of the 15th International Conference on Computer Aided Architectural Design Futures / ISBN 978-3-642-38973-3] Shanghai, China, July 3-5, 2013, pp. 295-305.
summary	The complexity of the requirements on buildings is continuously increasing and thus, often confronting designers with interdisciplinary problems, reaching far beyond the traditional challenges and methods of architecture and engineering. Moreover, designers are often required to take decisions, when most of the information and knowledge is still missing or to be generated. In the context of sustainable building design, the re-usability of building elements and the optimisation for exchangeability is crucial for the achievement of two of the main goals: efficient use of material resources and waste reduction. The scope of this work in progress is describing requirements for case-based decision support in order to optimise building element re-usability, create an analysis of explicit re-usability indicators (e.g. “connection liberation”, “modularity” or “life span collision”) and to identify retrieval strategies. A proposal to support decision making processes by retrieving existing design solutions graph representations as well as the use of building information models are also described.

summary	Assimilating Interactive Technology into Architectural Design – A Quest for developing an ‘Architectural Drawing’ for Urban Interaction Design as a Communication Platform Through Combining Physical Sensing Devices with Simulation Software The research presented in this paper investigates the need for an equivalent of architectural drawings for urban interaction design in an architectural scale in order to communicate interaction design intentions to design participants and clients through using state of the art computer, gaming and sensor technologies. The paper discusses two projects (a) Blur Building, as a large scale interaction design project executed through an experienced team and (b) presents as student design project coordinated by the researchers as a reference project. Both projects in this paper are discussed and evaluated from an Urban Interaction Design point of view. This paper emphasizes the significance for establishing ‘drawing’ equivalents for urban interaction design, discussing representation of ideas in architectural design; followed by outlining existing methods of interactive design representation, such as storyboards to then introduce current advancements in gaming environments. The following paper introduces a framework for future research projects that will design, deploy and evaluate of prototypes as a communication platform combining physical sensing devices in combination with gaming engines to enable a digital / physical hybrid. This would allow designers and clients to test, evaluate and improve urban interactions in a design phase prior to completing the project.

title	Adaptive Tectonic Systems: Parametric Modeling and Digital Fabrication of Precast Roofing Assemblies Toward Site-Specific Design Response
source	ACADIA 13: Adaptive Architecture [Proceedings of the 33rd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-926724-22-5] Cambridge 24-26 October, 2013), pp. 327-336
doi	https://doi.org/10.52842/conf.acadia.2013.327
summary	In order to design adaptable systems, the requirements include flexible models to generate a range of alternative configurations, analytical engines to evaluate performance, and well-defined selection criteria to identify suitable options. In most cases, design processes driven by performance concentrate on environmental or structural parameters; fabrication often remains disconnected from the generative process. Nonetheless, as design-to-fabrication methods become more robust, it is possible to extend the digital process to introduce fabrication variables to the definition of the project. The main focus of the research presented in this paper is the development of a digital and material workflow that connects design, structural and climate-specific topics (such as sun lighting and water drainage) toward producing a range of efficient structural and spatial assemblies.A case study serves as the main support for this investigation. Miguel Fisac’s “bones” is a light-weight roof system developed during the 1960’s, which had a very well-calibrated structural, natural-lighting, drainage and construction performance, as well as a highly refined spatial output. The system, despite its intelligence, lacked the flexibility possible today: using digital technologies, it can adapt to a significantly wider range of applications. Using “bones” as a starting point, this research develops a design-to-fabrication workflow that attempts to move forward tools, material systems and processes to enable an adaptable tectonic system.This paper describes the background research, concept, form-finding, construction process, methodology, results and conclusions of the investigation.

title	Following the Voice of the Crowd: Exploring Opportunities for Using Global Voting Data to Enrich Local Urban Context
source	Global Design and Local Materialization[Proceedings of the 15th International Conference on Computer Aided Architectural Design Futures / ISBN 978-3-642-38973-3] Shanghai, China, July 3-5, 2013, pp. 222-232.
summary	With the introduction of the internet to the public and the rise of digital technologies we experience a shift in our understanding of space. Mobile devices and ubiquitous computing in urban landscape make the physicality of distance disappear – the modern citizen is digitally connected to everybody at anytime and anywhere. The result of this network is a highly globalized world which effects economy same as personal interests and decisions of its inhabitants. The introduction of web 3.0 with its methods of comment, recommender and voting systems offers a broad platform for people all over the world to share experiences and exchange opinions about an unlimited variety of topics. Global opinions meet local interests. In this paper we explore the possibilities of using global voting data to enrich locally the modern citizen’s urban walking experience. We describe a new approach to wayfinding by implementing methods of digital recommender systems into the physical world. We investigate Facebook voting data to generate an alternative to the shortest route, as suggested by common route finder systems, in order to maximize the pleasure of an urban stroll. The testing of the system in a real world context together with collected feedback stimulate the discussions.

title	Toward a Computational Approach of Creativity Assessment in Product Design
source	Global Design and Local Materialization[Proceedings of the 15th International Conference on Computer Aided Architectural Design Futures / ISBN 978-3-642-38973-3] Shanghai, China, July 3-5, 2013, pp. 50-62.
summary	One of the most important criteria for the performance quality in design is the creativity of the design. Many researchers have developed methods to assess the creativity of product design, but the subjective and qualitative judgments of traditional creativity measurement are proved to lack sufficient validity and reliability. Furthermore, most of the assessment of creativity in design is based on the design outcome instead of the design process. In this paper, we proposed a computational approach of creativity assessment in product design via the combination of the design process and design creativity. We established a method to quantify the design process. And design creativity is rated using the Consensual Assessment Technique. Then the correlation of all the creativity-related factors in the design process and the design creativity will be calculated. Last, creativity assessment formula is proposed based on the factors and the correlation coefficient.

title	Log Knot

Online and Global. 24-30 October 2020. edited by M. Yablonina, A. Marcus, S. Doyle, M. del Campo, V. Ago, B. Slocum. 114-119.
summary	Log Knot, developed by the Robotic Construction Laboratory (RCL) at Cornell University, is a robotically fabricated architectural installation that establishes a method for variable compound timber curvature creation utilizing both regular and irregular roundwood geometries. Moreover, the project develops methods for minimal formwork assembly and moment force optimization of customized mortise and tenon joints. Following the logic of a figure-8 knot, the project consists of an infinite loop of roundwood, curving three-dimensionally along its length. There are a variety of techniques to generate single curvature in wood structures – such as steam bending (Wright et al., 2013) or glue lamination (Issa and Kmeid, 2005) – but only a few techniques to generate complex curvature from raw material within a single wooden structural element exist. To construct complex curvature, the research team developed a simple method that can easily be replicated. First, the log is compartmentalized, establishing a series of discrete parts. Second, the parts are reconfigured into a complex curvature “whole” by carefully manipulating the assembly angles and joints between the logs. Timber components reconfigured in such a manner can either follow planar curvature profiles or spatial compound curvature profiles. Based on knowledge gained from the initial joinery tests, the research team developed a custom tri-fold mortise and tenon joint, which is self-supportive during assembly and able to resist bending in multiple directions. Using the tri-fold mortise and tenon joint, a number of full-scale prototypes were created to test the structural capacity of the overall assembly. Various structural optimization protocols are deployed in the Log Knot project. While the global knot form is derived from spatial considerations – albeit within the structurally sound framework of a closed-loop knot structure – the project is structurally optimized at a local level, closely calibrating structural cross-sections, joinery details, and joint rotation in relation to prevailing load conditions.

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	The Architecture of ScarCity Game - The craft and the digital as an alternative design process

doi	https://doi.org/10.52842/conf.ecaade.2019.3.045
summary	The Architecture of ScarCity Game is a board game used as a pedagogical tool that challenges architecture students by involving them in a series of experimental design sessions to understand the design process of scarcity and the actual relation between the craft and the digital. This means "pragmatic delivery processes and material constraints, where the exchange between the artisan of handmade, representing local skills and technology of the digitally conceived is explored" (Huang 2013). The game focuses on understanding the different variables of the crafted design process of traditional communities under conditions of scarcity (Michel and Bevan 1992). This requires first analyzing the spatial environmental model of interaction, available human and natural resources, and the dynamic relationship of these variables in a digital era. In the first stage (Pre-Agency), the game set the concept of the craft by limiting students design exploration from a minimum possible perspective developing locally available resources and techniques. The key elements of the design process of traditional knowledge communities have to be identified (Preez 1984). In other words, this stage is driven by limited resources + chance + contingency. In the second stage (Post-Agency) students taking the architects´ role within this communities, have to speculate and explore the interface between the craft (local knowledge and low technological tools), and the digital represented by computation data, new technologies available and construction. This means the introduction of strategy + opportunity + chance as part of the design process. In this sense, the game has a life beyond its mechanics. This other life challenges the participants to exploit the possibilities of breaking the actual boundaries of design. The result is a tool to challenge conventional methods of teaching and leaning controlling a prescribed design process. It confronts the rules that professionals in this field take for granted. The game simulates a 'fake' reality by exploring in different ways with surveyed information. As a result, participants do not have anything 'real' to lose. Instead, they have all the freedom to innovate and be creative.

title	Design Constraint Systems - A Generative Approach to Architecture
source	International Journal of Architectural Computing vol. 11 - no. 1, 37-63
summary	Generative Architectural Design permits the automatic (or semiautomatic) generation of architectural objects for a wide range of applications, from archaeological research and reconstruction to digital sketching. In this paper the authors introduce design constraint systems (DCS), their approach to the generation of architectural design with the help of a simple example: The development of the necessary formalisms to generate a family of architectural designs, i.e. simple houses and pagodas. After explaining the formal system the authors introduce an approach for the generation of complex form based on the application of transformations and distortions.Architecture is bound by the constraints of physical reality: Gravitation and the properties of the used materials define the limits in which architectural design is possible. With the recent development of new materials and construction methods however, the ways in which form and physics go together get more complicated. As a result, the shapes of architecture gain more liberty, and more and more complex shapes and structures become possible.While these advances allow for new ways of architectural expression, they also make the design process much more challenging. For this reason new tools are necessary for making this complexity manageable for the architect and enable her to play and experiment with the new possibilities of complex shapes and structures. Design constraint systems can be used as tool for experimentation with complex form. Therefore, the authors dedicate the final part of this paper to a concise delineation of an approach for the generation of complex and irregular shapes and structures. While the examples used are simple, they give an idea of the generality of design constraint systems: By using a two-component approach to the generation of designs (the first component describes the abstract structure of the modelled objects while the second component interprets the structure and generates the actual geometric forms) and allowing the user to adjust both components freely, it can be adapted to all kind of different architectural styles, from historical to contemporary architecture.

summary	The aim of this paper is to design a public facilitie using both digital manufacture and rapid prototyping design methods. These new technologies have been used in product design development by some ways: helping in the comprehension of complex geometries; used as tools for analyzing the design process, thus avoiding errors in the project. The analysis were carried out using virtual simulation tests and physical prototype in reduced scale. The prototype was manufactured using the 3D printer V-Flash in the Virtual Design Laboratory – UFRGS, where positive and negatives aspects were identified and described.

doi	https://doi.org/10.52842/conf.acadia.2013.301
summary	Aggregate Architectures challenge the common notion of architectural structures as being immutable, permanent and controllable. Aggregate Architectures are understood as material systems consisting of large masses of granules—designed or natural—interacting with each other only through loose, frictional contact. As a consequence, they take the realm of structural stability and architectural planning into entire re-configurability and into merely probable predictions of their prospective behavior. This renders them relevant within the paradigm of Adaptive Architecture.The challenge to the designer is to move away from thinking in terms of clearly defined local and global assembly systems and to acquire tools and modes of design that allow for observation and interaction with the evolving granular architectures. In this context, the focus of the presented researchproject is on the relevance of mathematically based simulations as tools of investigation and design.The paper introduces the field of Aggregate Architectures. Consequently experimental and simulation methods for granulates will be outlined and compared. Different modeling and collision-detection methods for non-convex particles are shown and applied in benchmarking simulations for a full-scale architectural prototype. The potential for micro-mechanical simulation analysis within architectural applications are demonstrated and further areas of research outlined.

summary	In this paper we aimed at the development of a novel tool to facilitate the structured analysis of architectural construction principles, materials and production methods in digital design and fabrication practices. In order to assist the understanding and teaching of these subjects, we employed a taxonomy of spatial design construction (Vrouwe 2013). By using the taxonomy, we analysed and categorised 34 parametric structures published in the IJAC Journal (2002-2014). Informed by this study, we aligned the initial taxonomy using various framing strategies. As a result we developed a new framework for spatial design construction specifically customised for the design and fabrication of parametric structures which can potentially serve as a constructive tool to create a novel design learning environment and integrated teaching strategies.

summary	In this paper we examine the potential of combining 2D shape packing algorithms and evolutionary methods in the design process. We investigate the ways such algorithms can be used in architectural design and how they may influence it. In the first part of this paper we introduce the theoretical framework of packing algorithms and genetic algorithms as well as the traditional design process and the nature of design problems. In the second part of the paper we introduce a software prototype that tests these algorithms in two contexts: the preliminary design of a shading façade pattern and the design of commercial housing layouts. The aim for both experiments was to generate optimal configurations based on user-defined criteria without resorting to exhaustive search. Several lessons were learned that point to the potential of evolutionary methods in architecture as well as the limitations of such methods. We conclude the paper with recommendations for further developing this research project.
