summary	The rise of digital building models has devalued the broad domain of architectural visualization, a former core topic of the domain. At the same time, digital media has opened up new possibilities for interactive and explorative visual representations. Against this background the workshop advocates to rediscover visualization as a distinct topic in the context of architecture and construction. The workshop introduces a method and a theoretic framework for the creation of visual representations from building information models under involvement of architects and engineers as domain experts, and a prototypical implementation, which serves as a proof of concept and allows for the practical application of the method. The workshop presents the prototype based on selected hands-on examples.

title	Optimo: A BIM-based Multi-Objective Optimization Tool Utilizing Visual Programming for High Performance Building Design
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. 673-682

summary	Within the architecture, engineering, and construction (AEC) industry, the application of multidisciplinary optimization methods has been shown to reach significant improvements in building performance compared to conventional design methods. As a result, the use of multidisciplinary optimization in the process of design is growing and becoming a common method that provides desired performance feedback for decision making. However, there is a lack of BIM-based multidisciplinary optimization tools that use the rich information stored in Building Information Models (BIM) to help designers explore design alternatives across multiple competing design criteria. In this paper we introduce Optimo, an open-source visual programming-based Multi-Objective Optimization (MOO) tool, which is developed to parametrically interact with Autodesk Revit for BIM-based optimization. The paper details the development process of Optimo and also provides the initial validation of its results using optimization test functions. Finally, strengths, limitations, current adoption by academia and industry, and future improvements of Optimo for building performance optimization are discussed.

summary	The Processing language was created to teach programming to the design, architecture, and electronic arts communities. Despite its success, Processing has limited applicability in the architectural realm, as no CAD (Computer-Aided Design) or BIM (Building Information Modeling) application supports Processing. As a result, architects that have learnt Processing are unable to use the language in the context of modern, script-based, architectural work. This work joins Processing with the world of CAD or BIM applications, creating a solution that allows architects to prototype new designs using Processing and generate results in a CAD or BIM application. To achieve this, we developed an implementation of Processing for the Rosetta programming environment, allowing Processing scripts to generate 2D and 3D models in a variety of CAD or BIM applications, such as AutoCAD, Rhinoceros3D, SketchUp, and Revit.

summary	The building industry is a field even more complex, characterized by different risks which can deeply influence the success of a building construction process. Aim of this paper is to demonstrate how the risk, declined in the main aspects that affects the construction industry, can be properly modelled and reduced thanks to the innovation of existing design methods and tools.The goal is to enhance the BIM models with AR (augmented reality), in order to intervene in the risk management process, increasing the level of knowledge exchanged between actors and, consequently, reduce defects related to misunderstandings. This can be possible using AR visualizations on site and/or Virtual Reality (VR) simulations, oriented to inform via the easier perceptive channel -the sight- actors involved in the process.

title	Heuristic Optimization in Design

doi	https://doi.org/10.52842/conf.acadia.2015.357
summary	This paper presents a workflow called the ‘heuristic optimization workflow’ that integrates Octopus, a Multi-Objective Optimization (MOO) engine with Grasshopper3D, a parametric modeling tool, and multiple simulation software. It describes a process that enables the designer to integrate disparate domains via Octopus and complete a feedback loop with the developed interactive, real-time visualization tools. A retrospective design of the Bow Tower in Calgary is used as a test case to study the impact of the developed workflow and tools, as well as the impact of MOO on the performance of the solutions. The overall workflow makes MOO based results more accessible to designers and encourages a more interactive ‘heuristic’ exploration of various geometric and topological trajectories. The workflow also reduces design decision uncertainty and design cycle latency through the incorporation of a feedback loop between geometric models and their associated quantitative data. It is through the juxtaposition of extreme performing solutions that serendipity is created and the potential for better multiple performing solutions is increased.es responsive systems, which focus on the implementation of multi-objective adaptive design prototypes from sensored environments. The intention of the work is to investigate multi-objective criteria both as a material system and as a processing system by creating prototypes with structural integrity, where the thermal energy flow through the prototype, to be understood as a membrane, can be controlled and the visual transparency altered. The work shows performance based feedback systems and physical prototype models driven by information streaming, screening, and application.

summary	This paper explores hybrid digital / physical workflows in the building trades, a high-skill domain where human dexterity and craft can be augmented by the precision and repeatability of digital design and fabrication tools. In particular the paper highlights a project where historic techniques of decorative plastering are extended through live motion capture of a drawing implement, information rich visualization projected in the space of fabrication, and custom robotic tooling to generate free-form running moulds. This workflow allows designers and craftspeople to quickly explore patterns through free-hand sketch, test ideas with shaded previews, and seamlessly produce physical parts using robotic collaborators.

title	Hybrid Sentient Canopy: An implementation and visualization of proprioreceptive curiosity-based machine learning
source	ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 362-371
doi	https://doi.org/10.52842/conf.acadia.2016.362
summary	This paper describes the development of a sentient canopy that interacts with human visitors by using its own internal motivation. Modular curiosity-based machine learning behaviour is supported by a highly distributed system of microprocessor hardware integrated within interlinked cellular arrays of sound, light, kinetic actuators and proprioreceptive sensors in a resilient physical scaffolding system. The curiosity-based system involves exploration by employing an expert system composed of archives of information from preceding behaviours, calculating potential behaviours together with locations and applications, executing behaviour and comparing result to prediction. Prototype architectural structures entitled Sentient Canopy and Sentient Chamber developed during 2015 and 2016 were developed to support this interactive behaviour, integrating new communications protocols and firmware, and a hybrid proprioreceptive system that configured new electronics with sound, light, and motion sensing capable of internal machine sensing and externally- oriented sensing for human interaction. Proprioreception was implemented by producing custom electronics serving photoresistors, pitch-sensing microphones, and accelerometers for motion and position, coupled to sound, light and motion-based actuators and additional infrared sensors designed for sensing of human gestures. This configuration provided the machine system with the ability to calculate and detect real-time behaviour and to compare this to models of behaviour predicted within scripted routines. Testbeds located at the Living Architecture Systems Group/Philip Beesley Architect Inc. (LASG/PBAI, Waterloo/Toronto), Centre for Information Technology (CITA, Copenhagen) National Academy of Sciences (NAS) in Washington DC are illustrated.

summary	This paper explores the potential of using multiple software programs to generate an adaptable, cross-platform Building Information Network to unlock new territories of form-making and design. By using multiple software packages to overcome the limitations imposed by current BIM (Building Information Model) programs and mono-scalar design approaches, we can design a buildings form, envelope, and materiality through an adaptable, parametric design process that uses the best features of each software program, allows non-computational input to inform form, and takes advantage of a designer's unique self-expression.

summary	Numerous researchers point out that, in the early stages of architectural design, many significant decisions are taken to directly affect functional qualities, the performance of the building, aesthetics, and the relationship of the building with the natural environment and climate, even if there is no certain and valid information to create and obtain adequate design.In this paper, I particularly focus on the early stages of architectural design and search for the opportunities provided by Building Information Modeling (BIM) tools, towards the concept of performance analysis and parametric form seeking. Study also includes case study implementations which visualize the early processes of architectural design with benefits of BIM under different conditions to evaluate its opportunities during these design processes.

summary	Generative Design (GD) is a programming-based approach for Architecture that is becoming increasingly popular amongst architects. However, most Generative Design approaches were thought for traditional Computer Aided Design (CAD) tools and are not adequate for the Building Information Modeling (BIM) paradigm. This paper proposes a solution that extends GD to be used with BIM applications while preserving and taking advantage of its ideas. The solution will be evaluated by developing a connection between Revit, a well-known BIM tool, and Rosetta, a programming environment for GD, and by implementing the necessary programming language features that allows GD to be used in the context of BIM tool.

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	This work studies the Performance-Based Design approach, focusing exclusively on cost performance, asking how to launch the architectural portion thinking of the cost of the building in a way that such performance can directly influence the project design and architectural form and how can shape, type and structure of the building influence the final cost of the work. For this, we chose to analyze the DProfiler software for the development of models in order to produce an architectural form that directly meets the performance cost requirements, following specified formal language, which aligns cost and project intention in the initial phase of the design. The research showed that the use of Macro BIM software platform is promising and that the generative design process can and should arise from an organization of the parts and not from predefining it as a whole, achieving an architectural project that is attainable and more sustainable.

summary	In Classical Greece the design and construction of buildings were interconnected, forming a single activity. With the development of knowledge and technology, this process has fragmented, giving rise to different activities, performed by various professionals, such as the architect, the engineer and the builder, leading to problems related with information exchange between them. With the research projects Tecton and Technos, we intend to reunite these activities again, seeking to simplify the building production process. In Tecton, we propose an Immersive Virtual Reality Environment to sketch and model objects in an interactive way, using hand gestures and body postures, enabling architects to change between the viewpoint of the creator and that of the user, thereby designing buildings while experiencing them at full-scale at the same time. In the future Technos project, our vision is develop detailed 3D virtual models to serve both as supporting elements for the digital fabrication of building parts and as communications elements for the assembly and construction of buildings.

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	Previous research (Bourdakis et al, 2012; Papasarantou et al, 2013) dealt with the problem of creating information visualisation systems capable of combining historical data of MUCIV's database and developing strategies that embed the non-spatial data in spatial models. The database was primarily designed as an experimental flexible spatio-temporal configuration of dynamic visual structures generating a variety of narrations through interaction.The attempt of producing a legible configuration driven by a number of criteria, led to the proposition of two different arrangements, namely the linear and radial array. The aim of this paper is to present the next step on the visualization after redefining both the way that thematic axes and data are visualized and arranged/scattered. Alternate configurations are investigated, based also on theoretical analysis on the conceptualization and perception of information visualization systems (Card et al 1999, Ware, 2004).

summary	This paper discusses the potential of a BIM platform for offsite timber construction within the context of the UK construction industry. It examines the benefits, limitations, and challenges that BIM brings for offsite timber. Proof-of-concept projects are presented that deal with the architectural technology, structural engineering, and life cycle analysis aspects. These demonstrate the feasibility of the development of an open BIM platform which would establish a common standard for the industry. The paper concludes by suggesting an alternative business model for offsite timber construction, as enabled by Building Information Modelling.

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.

summary	Masonry Unit Database (MUD) is an integral part of Building Information Modeling for Masonry (BIM-M) initiative. MUD provides a data structure framework for storing the required data for digital representation of masonry units. Specific information about masonry units such as price, geometry and physical properties is needed throughout the lifecycle of a building project, including the design, construction, maintenance, and demolition stages. The development of MUD contributes to enhancement of masonry BIM tools for practitioners to incorporate up-to-date masonry product information into their projects. There are five main stages in the development of MUD: development of process map of masonry building project lifecycle, data requirement identification, physical design of database, design of data import structures, and finally design of data export structures. This paper focuses on the development of the SQL based MUD, and a Revit-Dynamo data export plugin for this database. The developed plugin is especially beneficial as it provides a tool for fast and accurate generation of the parametric and data enhanced masonry units as Revit families on the fly from the stored dimensions and attributes in the database. The generated masonry units with this method would be embedded in masonry wall systems in BIM building project.

summary	The BIM today can be a provider of inputs to performance analysis of different phenomena such as thermal comfort, energy consumption or winds. All these assessments are fundamental to the post occupation of the building. The attainment of approximate information of how the future building would behave under these conditions will reduce the waste of materials and energy resources. The same idea is used for evaluating the users occupation. Through simulation of human behavior is possible to evaluate which design elements can be improved. In complex structures such as hospital buildings or airports is quite complex for architects to determine optimal design solutions based on the tools available nowadays. These due to the fact users are not contemplated in the model. Part of the data used for the simulation can be derived from the BIM model. The three-dimensional model provides parametric information, however are not semantically enriched. They provide parameters to elements but not the connection between them, not the relationship. It means that during a simulation Virtual Users can recognize the elements represented in BIM models, but not what they mean, due to the lack of semantics. At the same time the built environment may assume different functions depending on the physical configuration or activities that are performed on it. The status of the space may reveal differences and these changes occur constantly and are dynamic. In an initial state, a room can be noisy and a moment later, quiet. This can determine what type of activities the space can support according to each change in status. In this study we demonstrate how the spaces can express different semantic information according to the activity performed on it. The aim of this paper is to simulate the activities carried out in the building and how they can generate different semantics to spaces according to the use given to it. Then we analyze the conditions to the implementation of this knowledge in the BIM model.

title	Facilitating fire and smoke simulation using Building Information Modeling
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. 383.
summary	CFAST is a two-zone model which simulates fire growth and smoke transport. Manually modeling a building using CFAST user interface is a time consuming and error-prone process. In addition, the limitations in CFAST structure impede data transfer between CFAST and BIM (Building Information Modeling). In this research, we identified major limitations of CFAST, proposed solutions to the limitations, and developed a system for data interchange between BIM and CFAST. This greatly facilitated fire and smoke simulation. We further developed a visualization module to visualize the simulation results to overcome the problems when using SmokeView, an application developed by NIST (National Institute of Standards and Technology). A pilot test is conducted using this system. The simulation process was done in just a few minutes. This is expected to help architects to design buildings safer from building fires, and help students in learning building safety and fire related building codes.
