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	Utilization of Simulation Tools in Early Design Phases Through Adaptive Detailing Strategies

summary	Decisions taken at early stages of building design have a significant effect on the planning steps for the entire lifetime of the project as well as the performance of the building throughout its lifecycle (MacLeamy 2004). Building Information Modelling (BIM) could bring forward and enhance the planning and decision-making processes by enabling the direct reuse of data hold by the model for diverse analysis and simulation tasks (Borrmann et al. 2015). The architect today besides a couple of simplified simulation tools almost exclusively uses his know-how for evaluating and comparing design variants in the early stages of design. This paper focuses on finding new ways to facilitate the use of analytical and simulation tools during the important early phases of conceptual building design, where the models are partially incomplete. The necessary enrichment and proper detailing of the design model could be achieved by means of dialogue-based interaction concepts with analytical and simulation tools through adaptive detailing strategies. This concept is explained using an example scenario for design process. A generic description of the aimed dialog-based interface to various simulation tools will also be discussed in this paper using an example scenario.

title	Error as Optimization - Using Cellular Automata Systems to Introduce Bias in Aggregation Models through Multigrids
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. 601-610

summary	This paper is focusing on the idea of error as the origin of difference in form but also as the path and the necessity for optimization. It describes the use of Cellular Automata (CA) for a series of structural and formal elements, whose proliferation is guided through sets of differential grids (multigrids) and leads to the buildup of big span structures and edifices as, for example, a cathedral. Starting from the error as the main idea/tool for optimization, taxonomies of morphological errors occur and at a next step, they are informed with contextual elements to produce an architectural system. A toolbox is composed that can be implemented in different scales and environmental parameters, providing variation, optimization, complexity and detail density. Different sets of experiments were created starting from linear structural elements and continuing to space dividers and larger surface components.

title	The geometry of Chuck Hoberman as the basis for the development of dynamic experimental structures
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. 485.
summary	The cognitive-theoretical foundation referring to teach drawing as a way of thinking, as well as the construction of the environment by means of drawing using transforming geometries and the formal and para-formal computational process, creating unusual geometries through generative design processes and methodologies, can be seen as some of the main possibilities in exploring dynamic experimental structures for an Adaptive Architecture. This article presents the development of a model for articulated facades, inspired by Hoberman´s Tessellates, and his Adaptive Building Initiative (ABI) project to develop facades models that respond in real time to environmental changes. In addition, we describe an experiment based on the retractable structures, inspired by Hoberman´s work and experimentations. Solutions for responsive facades can offer more flexible architectural solutions providing better use of natural light and contributing to saving energy. Using Rhinoceros and the Grasshopper for modeling and test the responsiveness, the parametric model was created to simulate geometric panels of hexagonal grids that would open and close in reaction to translational motion effects, regulating the amount of light that reaches the building.

title	Data-Insight-Driven Project Delivery: Approach to Accelerated Project Delivery Using Data Analytics, Data Mining and Data Visualization

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	The Usage of Application Autodesk 123D Catch® for Data Collection in the production of Learning Objects in Heritage Education
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. 497-501.
summary	This article deals with the technique of photogrammetry by using the Autodesk 123D Catch® application for registration of facades of historical and cultural buildings in the city of Salvador. Four trials are carried out in different complexities to test the tool’s potential. The Igreja and Convento de Nossa Senhora do Carmo, the chosen architectural elements are the door and the cover of the Church, as in the Palacete das Artes, the rear facade and one of the sculptures of the gardens. The 123D Catch® is efficient for the purpose of architectural records, however, there are still limitations of technical and spatial order to be observed.

summary	Advances in digital media are encouraging designers to adopt digital tools during early stages of design ideation as well as to facilitate collaboration in design teams. Collaborative environments for design teams should take into consideration both the multimodal nature of design representation as well as the complexity of team cognition. Collaborative tools that take a “black-box” approach often limit affordances for design ideation and collaboration. We describe here a collaborative environment that we put together using a kit-of-parts approach and underlying theoretical considerations. We also describe systematic usability evaluation of the collaborative environment by constraining select media affordances and qualitatively examining the impact on a team's design process. Preliminary findings were used to improve the environment and lay the groundwork for developing tele-collaborative environments.

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.

doi	https://doi.org/10.52842/conf.caadria.2015.209
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.

summary	The lack of urban planning has made the recreation areas increasingly smaller in the cities. Parks and squares gradually gave way to streets and avenues to try to accommodate the growing number of cars and motorcycles. An alternative that tries to balance recreation areas and urban roads was found in the city of San Francisco (USA). Parklets are temporary extensions of urban sidewalks that occupy a few parking spaces. This article aims to demonstrate the potential of parametric modeling in the development of parklets. Thus, anthropometric studies, amount of parking spaces and types of benches were used as input parameters. Rhinoceros and grasshopper programs were used for modeling, while 3D Studio Max was used for rendering. With this study it was possible to verify that when the project is parameterized the processes of creation and modification became faster, reducing design and implementation time.

title	Re-inventing ceramic tiles: Using shape grammars as a generative method and the impact on design methodology
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. 467.
summary	The following paper describes the process and results achieved with the workshop entitled ‘Re-inventing Portuguese ceramic tiles’ reflecting on design methodology and design teaching. Workshop participants were invited to rethink ceramic tile patterns developing a different process which used shape grammars as a generative system. Each participant group developed a three stage task using shape grammars principles and methodology. The preliminary results the work developed are of particular relevance in shape grammar research: firstly shape grammar formulae does not constitute an intuitive process to most creative designers which are often trained to design singular solutions for a specific problem, secondly more than one operative shape grammar can be formulated to represent the same corpus of solutions and lastly the generative potential of grammars transcends the normal capacities of the original grammarist aiding in design exploration and enlarging the corpus of feasible solutions. This paper also reflects on the impact of shape grammars as a design methodology.

summary	The article presents an Assistive Technology product design, which aims to overcome the medical product idea, considering its aesthetic configuration, and aims to change the concept of mass production into custom manufacturing. The methodological process was to obtain the user’s body 3D model, for subsequent parameterization by using the Grasshopper’s Rhinoceros Plugin software. It is believed that the digital manufacturing process provides a more flexible production, especially in the prototyping and testing stages, which seems a competitive advantage over companies that do not use them.

summary	The complexity of today´s architecture solutions brings the need to integrate, in the design process, digital tools for creation, visualization, representation and evaluation of design solutions. This paper proposes the adoption of a new Virtual Reality (VR) tool, referred to as VIARmodes, to support the architectural design process with an improved communication across different specialities, towards the facilitation of the project decision process. This tool allows a complete visualization of the design, specifically useful during the detailed design phase, including the architecture design and of other engineering specialities, progressively and interactively adapting the project visualization to the information needed for each discipline. With a set of 3 different visualization modes simulated in real scale within a Virtual Environment (VE), and adopting natural human-computer interaction by using speech, the system allows a team of architect and engineers, to visualize and interact with the proposed design during a collaborative design brief. We carried a usability evaluation study with 12 architects. The study showed that the tool was perceived to be effective and its use efficient during the design process, especially during the detailed design phase.

summary	This paper is a critical review on advantages and disadvantages of contemporary digital architecture, in retrospect to Vladimir Shukhov's design techniques, applied in the early 20th century. After investigating Shukhov's structural systems, this paper explores the relationship between performance and form, questioning the necessity of high-complexity structures. It will present unpublished archive material of his early work and stimulate a valuable discussion by comparing it with contemporary projects designed by renowned architects. The study on Shukhov focuses on his tessellation method of double-curved surfaces using simple standardized elements. The study of present digital approaches revolves around leading architects using computational tools (e.g. Foster and Partners, Buro Happold and Arup), who have materialized high complexity structures composed by irregular units. Our findings highlight advantages and disadvantages of contemporary computational approaches.

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.
