title	Pattern, cognition and spatial information processing: Representations of the spatial layout of architectural design with spatial-semantic analytics
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. 484.
summary	In this paper, we review and extend the idea of Alexander’s “pattern language”, especially from the viewpoints of complexity theories, information systems, and human-computer interaction, to explore spatial cognition-based design representations for “intelligent and adaptive/interactive environment” in architecture and urban planning. We propose a theoretic framework of design patterns “with spatial information processing”, and attempt to incorporate state-of-the-art computational methods of information visualization/visual analytics into the conventional CAAD approaches. Focused on the spatial-semantic analytics, together with abstract syntactic pattern representation, by using “spatial-semantic aware” graph grammar formalization, i.e., Spatial Graph Grammars (SGG), the relevant models, algorithms and tool are proposed. We testify our theoretic framework and computational tool VEGGIE (a Visual Environment of Graph Grammar Induction Engineering) by using actual architectural design works (spatial layout exemplars of a small office building and the three house projects by Frank Lloyd Wright) as study cases, so as to demonstrate our proposed approach for practical applications. The results are discussed and further research is suggested.

title	Articulated Timber Ground, Making Pavilion as Pedagogy
doi	https://doi.org/10.52842/conf.caadria.2015.023
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 23-32
summary	Designing and making a pavilion within a studio setting has been undertaken by various educators and researchers as a valuable pedagogy in the past 10 years. It aims to construct a collaborative environment that allows students to develop an integrated approach to learning; through association, teamwork and creative collaboration. Usually the tacit knowledge applied and acquired through making, and the knowledge of design strategy and analysis are separated in the way they are taught; it is often difficult to integrate these within the same coursework which often leads to students using digital software and fabrication tools as problem solving devices. This paper looks at an integrated approach to learning computational design and digital fabrication through the making of a pavilion by a Master level design studio. The paper discusses the pedagogy of making through creative collaboration and integrated workflow. It focuses on the use of digital and physical prototypes as devices to stimulate an oscillating dialogue between problem solving and puzzle making; a counterpoint for students to develop and search for new knowledge in order to create personalised learning experience. The paper concludes with an examination on the limits of digital prototype when interfaced with physical environment.

title	Tangible mixed reality on-site: Interactive augmented visualisations from architectural working models in urban design
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. 206.
summary	The consequences of architectural planning and design decisions made in the early design phases are hard to foresee. While professionals are used to reading plans and understanding architectural models, most laypeople are not familiar with their abstractions. This can lead to misinterpretations and misunderstandings between the different participants in the design process, especially in complex building situations, and decisions can be made or rejected that can have far-reaching consequences for the remainder of the project.In this paper we describe the concept and prototypical implementation of a decision-support system for the early design and discussion stages of urban de-sign projects that aims to address precisely this problem. The setup directly connects physical volumetric models and hand-drawn sketches with an interac-tive, mixed-reality visualization presented on a tablet or mobile phone, making it possible to see an interactive real-time view of an architectural design within the context of the actual site. In addition, the system is able to incorporate interactive simulations conducted on the model and presented in the AR-view.

title	A Framework for Input Data Processing During Building Energy Model Calibration. A Case Study
doi	https://doi.org/10.52842/conf.ecaade.2015.1.625
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 1, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 625-634
summary	Key parameter of a reasoning process supporting real time performance is the use of active heuristics that facilitate the achievement of goals in a timely manner (Dodiawala et al. 1989). A real time approach should incorporate speed, timeliness and adaptation during the execution of tasks. Speed and efficient knowledge processing are addressed for the solution of complex building engineering problems, such as the calibration of Building Energy Models (BEM) to the actual performance data. During retrofit projects, calibrated BEM models aid the design process, and provide a solid base for performative assessments. Despite the demand for building performance evaluations, BEM calibration remains a work-intensive task (Lam et al. 2014). This study proposes a time efficient framework for BEM calibration input data management based on the methodology of a blackboard artificial intelligence knowledge processing system. The resulting model was used for sequential data mining for the energy assessment during the renovation of a commercial building.

title	Integrating Responsive and Kinetic Systems in the Design Studio: A Pedagogical Framework
doi	https://doi.org/10.52842/conf.ecaade.2015.2.071
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 2, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 71-80
summary	Responsive architecture is one of the growing areas of computational design that is not getting adequate attention in CAAD curricula. A pedagogical approach to designing responsive systems requires more than the typical knowledge, tools or skill sets in architectural design studios. This paper presents a framework for integrating responsive and kinetic systems in the architectural design studio. The framework builds on findings of two design studios conducted at The American University in Cairo, Egypt. In both studios, students were asked to design elements of responsive architecture that work towards the development of their projects. The paper demonstrates the process and outcomes of both studios. It then demonstrates how concepts of integrated project delivery are incorporated to propose a framework that engages students in designing, fabricating and operating responsive systems in different phases of the design process. A discussion follows regarding dynamics of design studio in light of the proposed framework.

title	Making Sense of those Batteries and Wires: Parametric Design between Emergence and Autonomy
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. 279-296.
summary	This paper reports on the process and outcomes of a digital design studio that integrates parametric design and generative systems in architectural and urban design projects. It explores the interrelationship between the emergence of innovative formal representations using parametric design systems on the one hand, and design autonomy; more specifically the conscious process of generating and developing an architectural concept, on the other. Groups of undergraduate students working on an architectural project are asked to identify a specific conceptual parti that addresses an aspect of architectural quality, define strategies that satisfy those aspects, and computational methodologies to implement those strategies, such as rule-based systems, self-organization systems, and genetic algorithms. The paper describes the educational approach and studio outcomes, discusses implications for CAAD education and curricula, and addresses issues to be considered for parametric and generative software development.

title	Digital-Material Feedback in Architectural Design
doi	https://doi.org/10.52842/conf.caadria.2015.631
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 631-640
summary	This paper studies the architectural potential of the implementation of material feedback using computer vision before and during an automated fabrication process. The combination of an industrial robot and a 3D camera is used expand the typical one-way design and fabrication process (from a digital design to a physical output), to a feedback loop, where specific material information becomes the main trigger of design decisions and fabrication processes. Several projects developed by the authors and tested during a robotic workshop aim to unveil different aspects of material feedback in architectural design, opening a discussion for the benefit and challenges of this new approach to design and fabrication.

title	Data-Insight-Driven Project Delivery: Approach to Accelerated Project Delivery Using Data Analytics, Data Mining and Data Visualization
doi	https://doi.org/10.52842/conf.acadia.2017.102
source	ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 102-109
summary	Today, 98% of megaprojects face cost overruns or delays. The average cost increase is 80% and the average slippage is 20 months behind schedule (McKinsey 2015). It is becoming increasingly challenging to efficiently support the scale, complexity and ambition of these projects. Simultaneously, project data is being captured at growing rates. We continue to capture more data on a project than ever before. Total data captured back in 2009 in the construction industry reached over 51 petabytes, or 51 million gigabytes (Mckinsey 2016). It is becoming increasingly necessary to develop new ways to leverage our project data to better manage the complexity on our projects and allow the many stakeholders to make better more informed decisions. This paper focuses on utilizing advances in data mining, data analytics and data visualization as means to extract project information from massive datasets in a timely fashion to assist in making key informed decisions for project delivery. As part of this paper, we present an innovative new use of these technologies as applied to a large-scale infrastructural megaproject, to deliver a set of over 4,000 construction documents in a six-month period that has the potential to dramatically transform our industry and the way we deliver projects in the future. This paper describes a framework used to measure production performance as part of any project’s set of project controls for accelerated project delivery.

title	Osteotectonics - Trabecular Bone Structures and Their Adaptation for Customized Structural Nodes Using Additive Manufacturing Techniques
doi	https://doi.org/10.52842/conf.ecaade.2015.2.439
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 2, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 439-448
summary	This paper discusses an approach to adapting trabecular bone structures for the design of complex architectural components exemplified through structural nodes. Based on the paradigm shift in additive fabrication, namely the ability to print structural metals, this paper identifies new methods for architectural and structural design that allow to create porous, intricate architectural components. Those components are designed in analogy to bone structures. The paper presents a metaball-based application, programmed in Processing, which allows creating n-legged nodes using parametric gradient maps. The approach aims at reduction of weight and waste, while exploring the novel aesthetic properties of such bio-constructed networks.

title	Toward a Behavioral Design System: An Agent-Based Approach for Polygonal Surfaces Structures
doi	https://doi.org/10.52842/conf.acadia.2015.161
source	ACADIA 2105: Computational Ecologies: Design in the Anthropocene [Proceedings of the 35th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-53726-8] Cincinnati 19-25 October, 2015), pp. 161-172
summary	The following research investigates the development of an agent-based design method as an integrative design tool for polygonal surface structures. The aim of this research is to develop a computational tool that self-organizes the emergence of polygonal surface structures from interaction between its constitutive lattices. This research focuses on the ethological level of morphogenesis that is relevant to the animal or insect societies, whereby agents mediate the material organizations with environmental aspects. Meanwhile, behavior-based approaches are investigated as a bottom-up system to develop a computational framework in which the lower-level features constantly interact. The lower-level features such as material properties (e.g., geometric descriptions) are abstracted into building blocks or agents to construct the agent’s morphology. The abstracted principles, which define the agent’s morphology, are aggregated into a generative tool to explore the emergent complexities. This exploration coupled with the generative constraint mechanisms steers the collective agents system toward the cloud of solutions; hence, the collective behaviors of agents constitute the polygonal surface structures. This polygonal system is a bottom up approach of developing the complex surface that emerges through topological and topographical interaction between cells and their surrounding environment. Subsequently, the integrative system is developed through agent-based parametric modelling, in which the knowledge-based system as a top-down approach is substituted with the agent system together with its morphological features and significant behaviors.

title	The Problem of self-censorship in architectural students and the low cost tree-dimensional printers
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. 767-770.
summary	Self-censorship can be observed in architectural students. Due to drawing and development methods of design representation, some students do not create the design they dream about. Believing that you do not have the ability or the technique to represent the ideas on paper or using physical models can cause the self-censorship in the students. The production of physical models is very important for the design thinking and for architectural student’s experience. The tree-dimensional printers can help as a tool to print complex volumetric models or detailed models allowing students to create freely.

summary	An algorithm is a process of addressing a problem in a finite number of steps. In the context of architectural design, algorithmic thinking means taking on an interpretive role to understand the results in relation to design criteria, knowing how to modify the code to explore new options, and speculating on further design potentials. The application of algorithms within architecture often addresses the developed design stages, primarily to optimise structure, test environmental performance or to resolve complex construction. This research aims to explore algorithmic tools with a focus on early stage design. This design stage is often developed using traditional processes and is where algorithmic applications have been less successfully executed. The objectives are to algorithmically explore the areas of space planning, programme layout, form finding and form optimisation within early stage architectural design. Through the combination of a range of diverse algorithms, this research has an ultimate aim of integrating a computational workflow into practice at the early design stage.

title	Structural design based on performance applied to development of a lattice wind tower
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. 326.
summary	This paper studies the process of parametric and algorithmic design, integrating structural analysis and design for the generation of complex geometric structures. This methodology is based on the Performative Model, where the shape is generated using performance criteria. In the approach, the development of complex structures is only possible by reversing the process of thinking to generate the form with established parameters for geometry, material and loading aspects. Thus, the structural engineer no longer only participates in the evaluation phase but also appears in the early stages, creating a process of exploration and production of common knowledge among architects and engineers. To research performance-based design, the development of a conceptual lattice for a wind tower is proposed. Thus, a system is made to generate geometries using Rhinoceros software, the Grasshopper plugin, and the VB programming language, integrated with stress analysis through the Scan & Solve plugin.

summary	The underlying thesis of the research described in this paper is that imaginative, model-based explorations may help us better understand iconic architectural artefacts, such as cultural heritage projects. In order to systematically consider and study architectural artefacts, it is essential for academics to reach a level of clarity – and potentially even consensus – concerning the domains of architectural design that may be considered relevant and to question - often implicitly – shared conceptions. This paper intends to communicate the results and findings of an in-depth case-based exploration on the basis of ten design artefacts, using a specially developed conceptual framework. Furthermore, the aim was to draw conclusions concerning the benefits and potentials of this approach in the context of heritage-based architectural research in an academic environment.

title	Modulating Thermal Mass Behavior Through Surface Figuration
doi	https://doi.org/10.52842/conf.acadia.2017.202
source	ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 202-211
summary	This research builds upon a previous body of work focused on the relationship between surface geometry and heat transfer coefficients in thermal mass passive systems. It argues for the design of passive systems with higher fidelity to multivariable space between performance and perception. Rooted in the combination of form and matter, the intention is to instrumentalize design principles for the choreography of thermal gradients between buildings and their environment from experiential, spatial and topological perspectives (Figure 1). Our work is built upon the premise that complex geometries can be used to improve both the aesthetic and thermodynamic performance of passive building systems (Cupkova and Azel 2015) by actuating thermal performance through geometric parameters primarily due to convection. Currently, the engineering-oriented approach to the design of thermal mass relies on averaged thermal calculations (Holman 2002), which do not adequately describe the nuanced differences that can be produced by complex three-dimensional geometries of passive thermal mass systems. Using a combination of computational fluid dynamic simulations with physically measured data, we investigate the relationship of heat transfer coefficients related to parameters of surface geometry. Our measured results suggest that we can deliberately and significantly delay heat absorption re-radiation purely by changing the geometric surface pattern over the same thermal mass. The goal of this work is to offer designers a more robust rule set for understanding approximate thermal lag behaviors of complex geometric systems, with a focus on the design of geometric properties rather than complex thermal calculations.

summary	The approach of contemporary architecture with urban environment has always been in perpetual evolution. The path between concept and real building has been driven since ancient times by traditional drawing tools which discretized the architect ideas into shapes. The cases studied for morphogenesis evolution, featured in the top-notch architectural firms, have been framed into two different strategies. In the first family the shape is created by the modifications of several distinct geometrical elements, which create formal complexity. In the second family of buildings the complexity is the result of very few geometrical elements, whose morphogenetic process generates complex forms. As the geometrical elements decrease in number, the draft shape must undergo a deeper process of modification to solve the functional, sustainability and structural issues.

summary	Many situations related to natural environment and human activities increase the risk related to housing and create a demand for rapid post-disaster solutions. The solutions implemented by both the non-governmental organizations (NGOs) and the local and national organizations should fulfill the requirements of the temporarily displaced populations. However post-disaster design faces many challenges in its process making the response always more complex. At the same time, computer-based design is a growing approach in both architectural practice and research. The research described in this paper aims to help in finding solutions to design issues by addressing the potential of computer-based architectural design support. It is applied to shelter and camp development and takes into account physical, contextual and climatic parameters. The outcome is a design process for shelter and camp, which has been validated by a parametric prototype experiment in a case study. This should support humanitarian teams and contribute to enhancing the quality of design as well as to reducing the time required for the design and construction processes.

title	Analysis of Space Layout Using Attraction Force Model and Quadratic Assignment Problem

summary	This paper researches the usefulness of computerized space layout programs in an actual problem of space layout of more than 50 design units of unequal sizes. This was tested with two existing space layout optimization methods, Quadratic Assignment Problem (QAP) and Attraction Force Model (AFM) as well as a satisficing method, intuitive approach. Necessary inputs for the evaluation processes, the evaluation processes and the resulting space layouts were analyzed for each approach by one designer. Their performance in the design process was criticized on subjects like preparation of inputs, situations related with multiple trials, evaluation of the resulting space layouts based on given inputs and what those space layouts represented. Generating alternatives is an advantage of computerized space layout approaches so that conditioning on the resulting space layouts decreases in the process but more research has to be done for their practicality in terms of input preparation, evaluation and transfer of outputs. Possible improvements were suggested to increase their usefulness in the professional field.

summary	We introduce a parametric modeling method in the field of computer-aided architectural conception, which aims to produce non-standard wooden walls and envelopes with CNC machinery. This method explores the application of polygonal cellular structures (as patterns) on facade and envelope interventions for new and old projects. We innovate by bringing the 3D production environment complexity into the conception model to improve the production of manifold woodworking items by CNC (Computer Numerical Control) 3D fabrication. A recent experimentation, tests the entire workflow from parametric modeling to production of two full-scale prototypes. The results prove the range of inputs offered by the method to be functional, though it needs various improvements in order to optimize parametric modeling and digital fabrication procedures. Future research will focus on treating a wider range of joints via parametric modeling and deal with joint creation regardless wall deformation to expand the morphological approach of non-standard wooden walls design.

summary	With an exponential increase in the possibilities of computation and computer-controlled fabrication, high density information is becoming a reality in digital design and architecture. However, construction methods and industrial fabrication processes have not yet been reshaped to accommodate the recent changes in those disciplines. Although it is possible to build up complex simulations with millions of particles, the simulation is often disconnected from the actual fabrication process. Our research proposes a bridge between both stages, where one drives the other, producing a smooth transition from design to production. A particle in the digital domain becomes a drop of material in the construction method.The architect's medium of expression has become much more than a representational tool in the last century, and more recently it has evolved even beyond a series of rules to drive from design to production. The design system is the instruction itself; embedding structure, material and tectonics and gets delivered to the very end of the construction chain, where it gets materialised. The research showcased in this paper investigates tectonic systems associated with large scale 3D printing and additive manufacturing methods, inheriting both material properties and fabrication constraints at all stages from design to production. Computational models and custom design software packages are designed and developed as strategies to organise material in space in response to specific structural and logistical input.Although the research has developed a wide spectrum of 3D printing methods, this paper focuses only on two of the most recent projects, where different material and computational logics were investigated. The first, titled Filamentrics, intends to develop free-form space frames, overcoming their homogeneity by introducing robotic plastic extrusion. Through the use of custom made extruders a vast range of high resolution prototypes were developed, evolving the design process towards the fabrication of precise structures that can be materialised using additive manufacturing but without the use of a layered 3D printing method. Instead, material limitations were studied and embedded in custom algorithms that allow depositing material in the air for internal connectivity. The final result is a 3x2x2.5m structure that demonstrates the viability of this construction method for being implemented in more industrial scenarios.While Filamentrics is reshaping the way we could design and build light weight structures, the second project Microstrata aims to establish new construction methods for compression based materials. A layering 3D printing method combines both the deposition of the binder and the distribution of an interconnected network of capillaries. These capillaries are organised following structural principles, configuring a series of channels which are left empty within the mass. In a second stage aluminium is cast in this hollow space to build a continuous tension reinforcement.
