summary	Option one is the first prototype in the process of construction, based on the application of integrated processes of digital fabrication: This methodology was developed through a research project which explores options of rural public housing. The design process is integrated with other variables such as: participative design, directed self-build and the integration of tangible and intangible aspects. Parametric modeling was used as a strategy to create an integrated process of design, production and assembly based on a code created in grasshopper. Once finished, the housing unit will be handed over to a rural family. This will allow for doing follow-up and evaluation.

summary	With the comprehensive integration of software-based tools in actual processes of design development and fabrication, the boundaries between design and production become increasingly blurred. The methodology of the process of creation changes: the design development phase reaches up to the last produced model in a product series, in the same time the serial production cycle already starts with the first prototype.The aim of this research project is to explore and show the re-strengthening link between form, function, material and fabrication particularly driven by raising prominence of digital tools for design and production. Hereby the focus is on two points: the implementation of user data/input in the light of 'Open Innovation' as driver of form and function on one hand and the crafing inspired aproach of a comprehensive integration of material properties, behaviour tradional techniques of processing into the the design process.

summary	Building Information Modelling systems enable the creation of associative parametric models that include sets of interlinked parametric objects. Graph-based modelling systems on the other hand enable the creation of parametric models with more complex iterative behaviours. Parametric BIM workflows aim to link graph-based systems to BIM systems. A key requirement of such workflows is the ability to generate associative BIM models. However, current approaches to creating such workflows are complicated by the fact that the process of cooking is only able to generate explicit geometry. An alternative approach is proposed in which the cooking process is able to generate associative models, thereby enabling more user friendly and streamlined BIM workflows to be created.

summary	Facility management is aimed at energy saving, increasing the lifespan of buildings, enhancing the satisfaction of facility users and reducing running costs. To that end, it is important to grasp the conditions of the building in detail, and to analyze them one by one in order to execute building operation and maintenance strategically. However, conventional CAFM is insufficient. Therefore, we developed a system (called Building Information Management System) to utilize BIM data made on a Web site. We used groupware to support the system and an information platform that enables continuous management of a great variety of maintenance information. In addition, we developed a system to input information of building operation and maintenance using a mobile device on the site of checking and patrolling so as to reduce the burden of inputting information. A sensor network is used to acquire building operation and maintenance information to enhance building operation and maintenance. We also developed a system to automatically input sensing information into the building information for Building Information Management System, and to connect it with a 3D model. It has therefore become easier to collect the large amount of information necessary for strategic building operation and maintenance.

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.

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.

summary	Advancements in technologies provide Architects, today, with the means to expose new expressive forms using traditional materials. It is therefore possible to design dynamic actuating systems, where several different expressions, or differentiations inherent in the same material, are able to modify its topology and enhance its properties. Wood, traditionally used in construction, is given static expression during its life cycle, where an alignment, or assembly detail, helps retain its original shape. This research outlines the integration of specific and individual anatomical information of wood during the design process. It aids in utilizing the analyzed biological variability and natural irregularities of wood within a material-based architecture, in view of developing a lightweight, and light-filtering dynamic skin. Additionally, the research helps to explore an understanding of the differentiated material composition of wood as its major capacity, rather than its deficiency. Moreover, it analyzes form, material, and structure, as complex interrelations that are embedded in, and explored through an integral design process that seeks to employ typically disregarded, highly differentiated flat materials, in view of enhancing their latent dimensional deformation potential. The main focus of this research is to explore that latent geometric deformation of emerging patterns based on an array of heterogeneous wood veneers in relation to their Hygroscopic and Anisotropic properties. These properties are expressed through a set of flat skins and Mobius arrangements, articulating complex geometric ranges that reveal additional properties, such as bendability and flexibility.

summary	The chosen theme "Project Information for interaction" reveals one of the most important ways that technology has offered to improve the design process by integrating information into the elements of digital graphic in a parametric way. This integration allows many design professionals to interact on the same model, enabling simulations, materializations, revisions with data more close to the reality, avoiding errors and wastes. Projects with highest social responsibility can be performed by inserting this new way of designing in education and professional practices. So, this conference is dedicated to give time and space for presentations and discussions of researches and experiences in this area applied to the various fields such as Architecture, Urbanism, Design, Animation, Arts, among others. Looking into another perspective, this issue also brings the concept of Smart Cities, where the provision of information integrated with graphics inserted in the towns components (streets, open areas, buildings and objects), allow more responsible interactions, generating sustainable and collaborative actions among citizens.

summary	The AEC industry has been facing a digital transformation for improving services involved in buildings lifecycle, fostered by two disruptive technologies: Building Information Modelling (BIM) and Internet of Things (IoT). However, the literature lacks discussions regarding applications and challenges of BIM and IoT systems in the AEC. This Systematic Literature Mapping addresses this gap through search, analysis, and classification of 75 journal article abstracts published between 2015 and 2019. An increase of articles over the period is observed, predominantly with technical and processual solutions for Construction and Operation and Maintenance. The interoperability of data is a key challenge to organizations.

summary	To improve indoor thermal environment, it is necessary to promote a lean design process, so forecasting and consensus building by experiment and numerical calculation from the design stage have become essential. Rapid advances in software and hardware allow feedback to be generated on novel design alternatives, rather than relying on simulation results based on past designs. However, this concept has not been fully verified. Therefore, this study presents an integrated design tool which consists of Computational Fluid Dynamics (CFD), Virtual Reality (VR), Augmented Reality (AR) and Building Information Modeling (BIM). The tool was applied to the problems of an actual housing design project. Both the content of design feedback on design problems revealed through simulations in the project, and the features in the feedback process were discussed.

summary	The paper aims to address methods of realizing computationally generated self-organizing systems on a one-to-one scale with the employment of a singular material system. The case study described in this paper is the outcome of an investigation which has explored earth scaffolding, fabric form-work, and concrete materiality during an international three-week architecture workshop. Real-time generative form-finding methods based on branching and bundling systems in nature have been developed and simulated in an open-source programming environment. The outcome of the simulation stage has been analyzed structurally via Finite Element Analysis (FEA), results of which have served as inputs for the fine-tuning of the simulation. Final three-dimensional geometry has been fabricated by employing fabric, essentially forming the fabric form-work. Fabric form-work is then laid on top of the earth scaffolding, followed by the process of concrete casting. From a pedagogical point of view, the research focuses on the integration of digital design techniques between various design/architecture/analysis platforms combined with basic and advanced techniques of construction within a limited time frame.abstract here by clicking this paragraph.

summary	The pairing of CAD and GIS data creates an opportunity to connect an architectural design process more immediately with its environmental constraints. Yet the GIS data may be too overwhelmingly complex to be fully used in CAD without computer-assisted methods of highlighting relevant information. This paper reports on the implementation of an integrated environment for three-dimensional design geometrical modeling and obtaining environmental impact feedback. The project focused on enhancements to the data exchange and on the development of a related set of tools. While the technologies of CAD and GIS may rely on separate representational models,in combination they can provide a more complete view of the built and natural environment. The challenge in integration is that of bridging analytical methods and database formats used in the two technologies. Our approach is rooted in part in constraint based design methods well established in CAD (e.g., Sketchpad, Generative Components, CATIA). Within such CAD systems geometrical transformations may be intentionally constrained to help enforce some previously made design decisions. Although this current implementation modestly relates to geometrical constraints, the use of probabilistic risk values is more central to its methodology.

summary	While learning computer-aided modeling techniques, students of architecture should not only gain knowledge on how to model three-dimensional forms, but also how to define and understand the information beneath the shapes. Architectural presentation as an intellectual communication-focused process requires new media to channel information in a contemporary way. These can be text, image, sound, video or a digital model. The integration of augmented reality in teaching computer-aided modeling in architecture school provides more thorough learning experience as it opens new opportunities. The authors present the process of implementing AR technology in architectural education - its theoretical background, the outcome of students' work and technical solutions. They argue that the use of AR interface increases the effectiveness of user-model interaction in comparison to standard mouse-based techniques of three-dimensional manipulation due to the intuitive touch-screen interaction and direct control on the camera.

summary	Modular Light Cloud is an installation that is conceived to explore the boundaries of architecture and art. Its interactivity is a metaphor of mutual influences that derive from activities performed in space - associated with motion, sound and light.It is an experimental project focused on the integration of architectural elements, structure, information technology, performing arts, electronics and digital fabrication in architectural education.The project was completed in a two-week student workshop in collaboration with a contemporary dance artist. The students were taught the basics of parametric design, programming of electronic components and digital fabrication during tutorial classes. The making process combined three stages of development: design, construction and programming of interaction.The final form consists of two irregular spatial trusses made of aluminum profiles connected with 3d printed nodes. The profiles are equipped with LED strips and electronic components: light sensors, sound and communication between them. These systems control the intensity of light emitted by the diodes based on the inputs.The result is a working prototype presented as interactive installation featuring contemporary dance artist. It was displayed at art festivals and other events.

summary	This article discusses the development of a Speech Oriented Graphics Interface embedded in CAD and BIM software. The aim is to provide the means to work with complex 3D BIM models with minimal touch operations. We can cite the growing need for tools and user interfaces to assist designers in handling complex models, minimizing the risk of producing changes accidentally. In this area, the integration of a graphical database in BIM applications can be seen as an advantage over traditional CAD applications. However, we can note a difficulty in this integration, due to the need to maintain the constant levels of mental concentration required in order to effectively manage a larger inter-connected graphical database. Specifically in this area, voice interfaces can help by avoiding the need of "touch" to work with the 3D models, looking for improving its robustness and consistency. In addition, SR is used in order to reduce cognitive stress among the users, trying eliminating the need to memorize and remember commands, names and locations in GUI interfaces.

summary	In the natural world, biological matter is structured through growth and adaptation, resulting in hierarchically structured forms with tunable material computation. Conventional digital design tools and processes, by contrast, prioritize shape over matter, lacking integration between modeling, analysis, and fabrication. We present a novel computational environment and workflow for the design and additive manufacturing of large-scale hierarchically structured objects. The system, composed by custom multi-barrel deposition attached to robotic positioning, integrates material properties, fabrication constraints and environmental forces to design and construct full-scale architectural components. Such components are physically form-found by digitally extruding natural polymers with functionally graded mechanical and optical properties informed by desired functionality and executed through flow-based fabrication. In this approach, properties such as viscosity, velocity, and pressure embed information in two-dimensional printing patterns and induce three-dimensional shape formation of the fabricated part. As a result, the workflow associates physical material and fabrication constraints to virtual design tools for modeling and analysis, challenging traditional design workflows and prioritizing flow over form.

title	Distributed and heterogeneous data analysis for smart urban planning

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