title	Shared Realities: A Method for Adaptive Design Incorporating Real-Time User Feedback using Virtual Reality and 3D Depth-Sensing Systems
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. 330- 339

summary	When designing interactive architectural systems and environments, the ability to gather user feedback in real time provides valuable insight into how the system is received and ultimately performs. However, physically testing or simulating user behavior with an interactive system outside of the actual context of use can be challenging due to time constraints and assumptions that do not reflect accurate social, behavioral, or environmental conditions. Employing evidence based, user-centered design practices from the field of human–computer interaction (HCI) coupled with emerging architectural design methodologies creates new opportunities for achieving optimal system performance and design usability for interactive architectural systems. This paper presents a methodology for developing a mixed reality computational workflow combining 3D depth sensing and virtual reality (VR) to enable iterative user-centered design. Using an interactive museum installation as a case study, user pointcloud data is observed via VR at full scale and in real time for a new design feedback experience. Through this method, the designer is able to virtually position him/herself among the museum installation visitors in order to observe their actual behaviors in context and iteratively make modifications instantaneously. In essence, the designer and user effectively share the same prototypical design space in different realities. Experimental deployment and preliminary results of the shared reality workflow are presented to demonstrate the viability of the method for the museum installation case study and for future interactive architectural design applications. Contributions to computational design, technical challenges, and ethical considerations are discussed for future work.

summary	This paper examines the potential of utilizing virtual mock-ups in end user involvement processes. To access if virtual mock-ups can optimize existing processes, current workflows using physical full-scale mock-ups on several projects are explored. Requirements regarding the traditional workflows are captured through a series of interviews and observational studies. The identified use hereof is then analyzed and consolidated into system requirements and visions of a potential virtual supplement. Based on the identified requirements, a live prototype is developed supporting multiuser experiences in interactive environments through multiple and various devices such as CAVEs, HMD´s and touch devices supporting multi touch co-creation. Finally, the prototype is tested together with end users in ongoing projects to validate the potential of virtual mock-ups and to further detail the requirements to such a system.

summary	Urban vegetation has been used to tackle architectural and urban problems by reducing urban heat islands and improving the quality of urban landscapes and biodiversity. The green view index provides end users with a metric to intuitively understand the vegetation scenarios. This study integrates a green view index estimation method and augmented reality (AR) and diminished reality (DR) scenes of future architectural and urban design simulations. We developed the AR/DR system "PhotoAR+DR2016 (photogrammetry-based augmented and diminished reality)" that simultaneously measures the green view index and simulates building, urban, and planting designs with addition, demolition, and removal of the objects such as structures. The developed system enables real-time measurement of the green view index by appropriately reducing the image size and extracting the green area. Using the developed prototype system, the on-site verification can be conducted; in addition, the processing speed and the accuracy and inaccuracy rates can be measured, and the green view index can be sufficiently measured in real time.

title	Tangible Immersion for Ecological Design
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. 600- 609
doi	https://doi.org/10.52842/conf.acadia.2017.600
summary	We introduce tangible immersion—virtual reality coupled with tangible interaction—to foster interdisciplinary collaboration in a critical yet creative design process. Integrating tangible, embodied interaction with geospatial modeling and immersive virtual environments (IVE) can make 3D modeling fast and natural, while enhancing it with realistic graphics and quantitative analytics. We have developed Tangible Landscape, a technology that links a physical model with a geographic information system and 3D-modeling platform through a real-time cycle of interaction, 3D scanning, geospatial computation, and 3D rendering. With this technology, landscape architects, other professionals, and the public can collaboratively explore design alternatives through an iterative process of intuitive ideation, geocomputational analysis, realistic rendering, and critical analysis. This is demonstrated with a test case for interdisciplinary problem-solving, in which a landscape architect and geoscientist use Tangible Landscape to collaboratively design landforms, hydrologic systems, planting, and a trail network for a brownfield site. Using this tangible immersive environment they rapidly explored alternative scenarios. We discuss how the participants used real-time analytics to collaboratively assess trade-offs between environmental and experiential factors, balancing landscape complexity, biodiversity, remediation capacity, and aesthetics. Together they explored how the relationship between landforms and natural processes affected the performance of the designed landscape. Technologies that couple tangible geospatial modeling with IVEs have the potential to transform the design process by breaking down disciplinary boundaries, but may also offer new ways to imagine space and democratize design.

summary	The renovation projects to improve the thermal environment are gaining importance because of energy saving effects and occupants' health considerations. However, the indoor thermal design is not usu-ally performed in a very efficient manner by owners and designers because the architectural design data including the indoor thermal design is not centrally managed among all professional designers. Additionally, the visualizations of the CFD simulation results are difficult for the stakeholders to understand. On the other hand, greenery has been introduced to buildings as a method for adjusting the thermal condition. The research goal presented in this paper is to investigate a cooperative architectural design process for the thermal environment by developing a system in which BIM, CFD, and AR are integrated to provide interactive visualizations. Case studies are performed to verify the developed system and to assess the thermal effects of multiple indoor greenery design options.

title	Development of parametric CAAD models for the additive manufacturing of scalable architectural models
source	Fioravanti, A, Cursi, S, Elahmar, S, Gargaro, S, Loffreda, G, Novembri, G, Trento, A (eds.), ShoCK! - Sharing Computational Knowledge! - Proceedings of the 35th eCAADe Conference - Volume 1, Sapienza University of Rome, Rome, Italy, 20-22 September 2017, pp. 419-426

summary	Architecture models are an essential component of the development process and enable a physical representation of virtual designs. In addition to the conventional methods of model production using the machining of models made of wood, metal, plastic or glass, a number of additive manufacturing processes are now available. These new processes enable the additive manufacturing of architectural models directly from CAAD or BIM data. However, the boundary conditions applicable to the ability to manufacture models with additive manufacturing processes must also be considered. Such conditions include the minimum wall thickness, which depends on the applied additive manufacturing process and the materials used. Moreover, the need for the removal of support structures after the additive manufacturing process must also be considered. In general, a change in the scale of these models is only possible at very high effort. In order to allow these restrictions to be adequately incorporated into the CAAD model, this contribution develops a parametrized CAAD model that allows such boundary conditions to be modified and adapted while complying with the scale. Usability of this new method is illustrated and explained in detail in a case study. In addition, this article addresses the additive manufacturing processes including subsequent post-processing.

summary	Designing colours for architecture with digital tools is still a challenging topic. Especially for customers and students the perception of a full-scale coloured interior room is hard to imagine. This paper presents a software prototype and a small user study, which addresses the colour design process with professional digital tools and a virtual reality head mounted device (Oculus Rift DK2). The user can navigate within an imported three-dimensional model freely and change colour, texture and light properties with a real-time updated radiosity visualization. The presented user study compares a screen based working method with the developed virtual reality based design support and interaction method.

summary	Art and architectural history education has long relied on photographic imagery. The geography of architectural history often demands an analog representation for the built form and photographic recordings have long been the widely adopted standard. In many cases, specific buildings have been taught for generations based on a handful of historical exposures. The impact of this precedent is an imperfect and highly privileged conception of architectural forms. Students learn only of a particular viewpoint of any given building, rather than understanding the building as a whole. Augmenting the tradition of select and static imagery in the classroom with new technologies can create a more comprehensive understanding of architectural precedents. This paper discusses an experiment conducted in Spring 2017 in presenting an architectural case study to a history class using a Virtual Reality 3D experience in comparison to a set of canonical photographs.

summary	Considering the outdoor environment at the initial stage of design process plays a significant role on future building performance. Augmented Reality (AR) technology applied in this research can integrate real world building morphology information and virtual world ventilation information seamlessly that rapidly and directly provides designers information for observation and evaluation. During the case study of "2017 Shanghai DigitalFUTURE" summer workshop, a research on augmented reality technology based wind environment visualization was carried on. The achievement with an application software not only showed the geometric information of the real world objects (such as buildings), but also the virtual wind environment has displayed. Thus, these two kinds of information can complement and superimpose each other. This AR technology based software brings multiple synthetic together, which can (1) visualize the air flow around buildings that provides designers rapid and direct information for evaluation; (2) deal with wind-environment-related data quantitatively and present in an intuitive, easy-to-interpret graphical way; and (3) be further developed as a visualization system based on built-in environments in the future, which contributes to rapid evaluation of a series of programs at the beginning of the building design.

title	An Italian BIM-based portal to support collaborative design and construction - A case study on an enhanced use of information relying on a classification system and computational technical datasheets

summary	A great amount of information needs to be managed along the building life cycle in order to fulfil building codes, standards and regulations, client and user requirements. However, a lack of transparency in the information management and a lack of communication between stakeholders often bring to the adoption of solutions in the design process that do not meet the original requirements. Therefore, an ordered structure for information improves its storage, enhancing its visibility, traceability, usability and re-usability. In addition, for public works contracts and design contests, the use of specific electronic tools, such as building information electronic modelling tools, is often required for the information management. The paper presents the efforts devoted within the Italian building sector for proposing a standardized structure and developing tools for collecting, sharing and exchanging information between stakeholders involved in different stages of the building process. An enhanced use of information relying on the adoption of the standardized structure of information is presented, proposing dedicated applications for automating the process of information fruition.

summary	The paper presents research on how Building Information Modelling (BIM) can be applied comprehensively throughout the design of an architectural project. A practical method based on BIM models that help to deal with multidisciplinary issues by integrating the design information from different sources, collaborators and project stages is formulated by adopting existing available tools. The ‘Tiantian Square’ building project in Wuhan, China combines a subway station with a commercial hug. According to the project’s size and complexity, our study focuses on the multiple cooperation of professionals from different backgrounds, including the departments of architectural design, structure (civil engineering), HVAC (Heating, Ventilation and Air Conditioning), water supply and drainage, and electrics and sustainable design. Our paper presents how the BIM model bridges between various simulation platforms through our technical system and management, including steps of transformation, simplification, analysis, reaction and improvement. Our research has helped to improve the overall efficiency and quality of the project. We generated a successful analysis-design approach for the initial design stages, which does not require in-depth analysis. It is a practical method to immediately evaluate the performance for each design alternative and provide guidelines for design modification. Finally, we discuss how the coordination of different department becomes a crucial factor as we look forward to a more open, communicative and inter-relational design and development process.

title	Towards Intelligent Control in Generative Design

summary	This position paper proposes and defines the nature of a framework, which explores ways of integrating control system (CS) with machine intelligence for generative design (GD). This paper elaborates about the implications of and the potential for impact on GD. The framework described in this work can be used as an active tool to drive design processes and support decision making process in early stages of architectural design. This type of system can be either automated in nature or adaptive to regular user input as part of interactive design mechanisms. The module of CS in the framework would allow additional guidance during design and therefore reduce the need of manual input to enable a semi-automated design practice for lengthy generative processes. This study on GD reveals emergent properties of the framework, for example the introduction of intelligent control allows guidance of GD to meet specified performance criteria and intended aesthetic expressions with reduced need for user interaction.

doi	https://doi.org/10.52842/conf.caadria.2017.023
summary	This paper presents the experience of the first phase of remodeling existing historical and colonial district in Bandung, Indonesia, including existing building façade, streetscape and street furniture. Braga Street is chosen as study case because it is a well-known historical street in Bandung with art deco style buildings constructed during Dutch colonial era. By remodeling it, it could help stakeholders to evaluate existing Braga street condition, to test any modification of buildings along the street and to determine specific regulation for the street. In this case, we use Unity3D and Oculus Rift DK2 for remodeling current situation. We gathered feedback from respondents using a questionnaire given after they experienced the model in VR. Many lessons learned from modeling process and respondents' feedback: higher frame rate to make seamless VR experience by having all components on a low poly model and provide smoother movement to prevent visual discomfort. This paper's conclusion gives suggestions for anyone who want to start architecture modeling in virtual reality for the very first time and how to optimize it.

summary	Computational visual simulations are extremely useful and powerful tools for decision-making. The use of virtual and augmented reality (VR/AR) has become a common phenomenon due to real-time and interactive visual simulation tools in architectural and urban design studies and presentations. In this study, a demonstration is performed to integrate Structure from Motion (SfM) into VR and AR. A 3D modeling method is explored by SfM under realtime rendering as a solution for the modeling cost in large-scale VR. The study examines the application of camera parameters of SfM to realize an appropriate registration and tracking accuracy in marker-less AR to visualize full-scale design projects on a planned construction site. The proposed approach is applied to plural real architectural and urban design projects, and results indicate the feasibility and effectiveness of the proposed approach.

summary	With the rapid advances in technology, virtual reality(VR) re-emerged as an affordable technology providing new potentials for virtual learning environments(VLE). Within the scope of this study, firstly a general perspective on potentials of VR to create an appropriate VLE is put forward regarding the potentials related with learning modalities. Then, VR as a VLE in architectural education is discussed and utilization of VR is revisited considering the fundamentals of education as how to enhance skills regarding creativity, furnish students to adopt future skills and how VR can be used to enhance design understanding as well as space perception and spatial relations. It is deliberated that instead of mirroring the real spaces, allowing students to understand the virtuality with its own constituents will broaden the understanding of space, spatial relations, scale, motion, and time both in physical and virtual. The dichotomy between physical and virtual materiality, the potentials and pitfalls in the process of transformation from real/physical to virtual - virtual to real/physical are discussed in relation with the student projects designed in the scope of Digital Design Studio course in Middle East Technical University. It is also shown that VR stimulates different learning modalities especially kinesthetic modality and helping students to develop creativity and metacognition about space and spatial relations.

Applications in architecture, engineering and construction are getting more attention as 3D printing is trying to find its place in the industry. Due to high material prices for metal 3d printing and in-homogenous material behaviour in printed plastic, 3D printing has not yet had a very significant impact at the scale of buildings. Limitations on scale, cost, and structural performance have also hindered the advancement of the technology and research up to this point. The research presented here takes a case study for the application of 3D printing at a furniture scale based on a novel custom optimisation approach for structural nodes. Through the concentration of non-standard geometry on the highly complex custom optimised nodes, 3D printers at industrial product scale could be used for the additive manufacture of the structural nodes. This research presents a design strategy with a digital process chain using parametric modeling, virtual prototyping, structural simulation, custom optimisation and additive CAD/CAM for a digital workflow from design to production. Consequently, the digital process chain for the development of structural nodes was closed in a holistic manner at a suitable scale.

summary	To construct a building that meets the requirements of certification in terms of environmental friendliness, there must be a process that considers the certification criteria from the initial design phase. However, there are numerous complicated task performance procedures to analyse many required items in detail as well as perceive and apply the data requirements efficiently. Currently, Building Information Modeling (BIM) is gaining attention as a solution for environmental problems in architecture. BIM shows precisely how a virtual building is modelled in the real world, thereby providing an objective information and analysis through a simulation. However, the result values of BIM library or modelling may turn out differently as a result of the work environment of designers or users that is not standardized. Therefore, this study applies the modelled and extracted BIM data using the template and library established in the BIM add-in planning and design phase to review in advance the Green Standard for Energy and Environmental Design (G-SEED) assessment by item and manual input of users with the BIM-based (add-in) G-SEED assessment system, thereby providing support to enable users to establish specific strategies in designing green buildings.

summary	The trajectory of virtual reality for architecture is towards photo-realism. While this may be effective for some contexts, we propose that abstraction is more appropriate for the purposes of a historian interpreting drawings of unbuilt works of architecture. The case study we are using to explore this proposition is the Palazzo Littorio competition set in 1934 Rome. We present two prototype immersive virtual reality (iVR) applications developed in Unity for Oculus Rift: the first uses an etching aesthetic to produce a quasi-realistic site context and an interface that enables the comparative evaluation of competition entries from key viewing positions; the second application takes an even more abstract approach, where the aim is to immerse the historian within a 3D drawing, along with other historical material (drawings, photos, paintings, narrations of texts) and uses spatialized sound to evoke the ambience of the period.
