title Humanising the Computational Design Process - Integrating Parametric Models with Qualitative Dimensions
source Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 9-18
summary Parametric design is a computational-based approach used for understanding the logic and the language embedded in the design process algorithmically and mathematically. Currently, the main focus of computational models, such as shape grammar and space syntax, is primarily limited to formal and spatial requirements of the design problem. Yet, qualitative factors, such as social, cultural and contextual aspects, are also important dimensions in solving architectural design problems. In this paper, an overview of the advantages and implications of the current methods is presented. It also puts forward a ‘structured analytical system’ that combines the formal and geometric properties of the design, with descriptions that reflect the spatial, social and environmental patterns. This syntactic-discursive model is applied for encoding vernacular courtyard houses in the hot-arid regions of the Middle East and North Africa, and utilising the potentials of these cases in reflecting the lifestyle and the cultural values of the society, such as privacy, human-spatial behaviour, the social life inside the house, the hierarchy of spaces, the segregation and seclusion of family members from visitors and the orientation of spaces. The output of this analytical phase prepares the groundwork for the development of socio-spatial grammar for contemporary tall residential buildings that gives the designer the ability to reveal logical spatial topologies based on socio-environmental restrictions, and to produce alternatives that have an identity while also respecting the context, place and needs of users.

summary This paper discusses the development of an interactive and a responsive Tangible User-Interface (TUI) for parametric and Building Information Modeling (BIM) applications. The prototypes presented in this paper utilizes physical computing systems to establish a flexible and intuitive method to engage digital design processes.The prototypes are hybrid UIs that consist of a digital modeling tool and an artifact. The artifact consists of a control system (sensors, actuators, and microcontrollers) and physical objects (architectural elements). The link between both environments associates physical objects with their digital design information to assist users in the digital design process. The integration of physical computing systems will enable the objects to physically respond to analog input and provide real-time feedback to users. The research aims to foster tangible computing methods to extend the capabilities of digital design tools. The prototypes demonstrate a method that allows architects to simultaneously interact with complex architectural systems digitally and physically.

title Multiflight - Creating Interactive Stairs through Positive Technology
source Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 295-308
summary This paper details a pedagogical project which calls for an improved design performance of the existing built environment through the use of smart technology and data-driven design. The project is an investigation into ways in which to improve the performance of a ‘pre-selected university building’ through the use of a media facade that allows for interactive experiences. Existing problems of the selected building have been identified through observation and research using a rich picture and agile approach. An underutilised staircase was selected as the focus site for a series of computational design and interactive design studies. The brief of this mini-research project aims to encourage more people to use the stairs and create a memorable experience with a technological approach through the application of a site specific interactive media installation. The project is an interactive staircase which utilises LED strips and generative sound. The project features a series of light boxes which are connected to the existing staircase balustrade. Arduino, passive infra-red sensors, and other motion detection sensors were used to allow for light and generative sound interaction with users using visual scripting tools and a generative design platform. Sensing technology was used as a real-time data-gathering device during the site analysis phase as well as an input device for the designed prototype to allow the testing of the data-driven design. This paper details the study and resultant interactive prototypes. It also discusses the exploration of performance based design ideas into design workflows and the integration of sensing tools into the design process. It concludes by identifying possible implications on using the Internet of Things concepts to facilitate the design of interactive architecture.

title Narrative Architectural Fiction in Mentally Built Environments
source Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 283-294
summary A thin line lies between reality and fiction; what is mentally imagined and what is visualized. It all depends on how ideas and images are perceived or what neurological activity is triggered in the user’s brain. Architects and designers spare no effort or tools in presenting buildings, architecture or designs in all forms or ways that would augment users’ experience whether on the perceptual or the cognitive level and in both the digital or the physical environments. In a progressive tendency they, the designers, tend to rely more and more on digitizing their vision and mission, which subsequently give them, impressive and expressive superiority, that would influence the users conscious on the one hand and manipulate their subconscious on the other. Within that process designers work hard to break any mental firewall that would prevent their ideas from pervading the space of any mental environment the user, build or visualize. In that context, to what extent such ways of mental entertainments used by architects, legitimize deception in design? What distinguishes employing the rhythmic simulation of the narrative fictional inceptions (virtual reality) from deploying the adaptive stimulation of the experience modeling conceptions. The difference between planting an idea and constructing an idea. It is not the intention of the paper to prove the failure of the computer aided design neither to stand against the digital architectural design media and applications development. It is rather to present a different way of understanding of how architectural design whether virtual, digital, or real can stimulates and induces codes and messages that is correlated to the brainwave cognitive attributes and can generate a narrative brain environment where the brain can construct and simulate its own fictional design. Doing so, the paper will review certain experimental architectural events and activities which integrate sound and sight elements and effects within some electronic, technical and digital environments.

title Evolutionary Solar Architecture - Generative Solar Design Through Soft Forms and Rigid Logics
source Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 55-64
summary This paper describes the development of a workflow for the production of a net zero off-grid research cabin.  The workflow deploys a number of affiliated parametric software packages as a form finding tool for the exterior envelope of this structure, with a focus on passive solar design as a generative formal driver. The design was required to incorporate the spatial and programmatic needs of the users in a compact, barrier free, net zero building. Simultaneously, the research question asked the designers to harness the potential of digital design in the consideration of future fabrication techniques, in order to optimize the building’s performance and the speed and quality of assembly once the project moves into construction. Parameters considered include solar exposure, external surface area, cost, fabrication, functionality, and aesthetic criteria. This project was developed by a multidisciplinary team of graduate students at the University of Calgary.

title Plug-In Design - Reactivating the Cities with responsive Micro-Architectures. The Reciprocal Experience
doi https://doi.org/10.52842/conf.ecaade.2017.2.571

summary Every city has under utilized spaces that create a series of serious negative effects. Waiting for major interventions, those spaces can be reactivated and revitalized with soft temporary projects: micro interventions that light up the attention, give new meaning and add a new reading to abandoned spaces. We can call this kind of operations "plug-in design", inheriting the term from computer architecture: interventions which aim to involve the citizens and activate the environment, engage multiple catalyst processes and civil actions. Plug-in design interventions are by all meanings experimental, they seek for interaction with the users, locally and globally. Information Technology - with its parametric and site-specific capabilities and interactive features - can be instrumental to create such designs and generate a new consciousness of the existing environment. With this paper we will illustrate how two low-budget interventions have re-activated a forgotten public space. Parametric design with a specific script allowing site-specific design, materials and structure optimization and a series of interactive features, will be presented through Reciprocal 1.0 and Reciprocal 2.0 projects which have been built in 2016 in Italy by the nITro group.

summary For several years great effort has been devoted to the study of Architectural Design Optimization (ADO). However, although in the recent years ADO has attracted much attention from academia, optimization methods and tools have had a limited influence on the architectural profession. The aim of the study is to reveal users' expectations from the optimization tools and define limitations preventing wide-spread adaptation of the optimization solvers in the architectural practice. The paper presents the results of the survey "Optimization in the architectural practice" conducted between December 2015 and February 2016 on 165 architectural trainees and practising architects from 34 countries. The results show that there is a need for an interactive multi-objective optimization tool, as 78% respondents declared that a multi-objective optimization is more necessary in their practice than a single objective one and 91% of them acknowledged the need for choice of promising solutions during optimization process. Finally, it has been found that daylight, structure and geometry are three top factors which architects are interested in optimizing.

summary This article delineates the process of developing the project "Urbanimals" - an interactive installation designed and realised in Bristol, UK, in 2015. As the case study research, it draws attention to the difficulties in designing interactive structures in urban spaces - from an architects' idea to a construction stage. There are four areas that are being investigated: (1) Modelling interactions, (2) Negotiating locations and logistics, (3) Developing hardware and (4) Performing the on-site observations. The project draws from the idea of Smart City (SC) as the concept of the urban environment with a certain level of responsiveness through implementing a technology-driven matter that expands city offer perceivable, but gentle and not hindering way. It highlights the possible applications of projection technology and the utilisation of the 3D modelling software which provides complex tools for creating animations, movements and interactions with future users. The article gives clues how to design more engaging interactions and how to deal with implementing them in public realm.

title VR or Not VR - No Longer a Question?

summary Virtual Reality (VR) software has developed to the point where, for the architect who is averagely technically adept, it can be incorporated into the design process with reasonable effort and costs. For VR to be an effective design tool, it must add value to the design process and should give insights and opportunities not available by other methods.Previous research by the authors reported on the results of an international student workshop which focused both on the workflow (to prepare the architectural models for the new VR systems) and the spatial perception that users experienced. In this paper, we continue to explore the question: "Can low cost VR be an effective addition to the architects' design toolbox, or does it still remain a "far-fetched, high-tech expensive folly?"To do this we are working with a larger group of students, a more developed workflow and we are also expanding this to architects in practice. We will be assessing both the practicality of integrating VR into the design workflow and the spatial perception of the designer when interacting with the model. We are experimenting with additional interface tools.

title Hyve-3D and the 3D Cursor: Architectural co-design with freedom in Virtual Reality
source International Journal of Architectural Computing vol. 14 - no. 2, 87-102
summary Hybrid Virtual Environment 3D (Hyve-3D) is a system that allows architectural co-design inside Virtual Reality by a new model of interaction through a 3D cursor. It augments the concept of the cursor to better interact with three- dimensional virtual spaces, rethinking it as a drawing/control plane and viewpoints inside the virtual world. Handheld tablets intuitively manipulate 3D cursors. Users can simultaneously access their individual complementary views on the tablets as personal windows into the shared immersive display. They can concurrently sketch in three dimensions, transform, and manipulate three-dimensional objects using the tablets as tangible props and collectively navigate the scene using the tablet as a 3D trackpad. The system implementation and co-design assessments of different settings are presented.

title Architectural Space Planning Using Parametric Modeling - Egyptian National Housing Project
source Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 45-54
summary The Egyptian government resorts to prototype housing for low-income citizens to meet the growing demand of the housing market. The problem with the prototype is that it does not meet specific needs. Consequently, users make modifications to the prototype without professional intervention because of the high cost. This paper discusses an automatic multi-stories space planning tool that helps low-income citizens to modify their prototype housing provided by the government. Social, spatial and functional design aspects were set in the original design prototype by an architect. The proposed tool simulates spaces spatial locations in the original design by simulating the analogy of mechanical springs through an interactive simulation of a parametric model. The authors developed the used algorithm in the generative design tool Grasshopper and the live physics engine Kangaroo, both working within the Rhino 3D environment. The algorithm has two versions, one-floor level version and two floors version targeting the wealthier users. Results indicate that this tool integrates with the exploratory nature of the design process even for non-professional users. The authors designed a tool that will help the users to study the effect of the desired modifications against the originally provided prototype, it also makes it easier for users to express their requirements to a professional designer, conserving time and financial cost.

title Printing Compound-Curved Sandwich Structures with Robotic Multi-Bias Additive Manufacturing
doi https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_44
source Proceedings of the 2023 DigitalFUTURES The 5st International Conference on Computational Design and Robotic Fabrication (CDRF 2023)
summary A research team at Florida International University Robotics and Digital Fabrication Lab has developed a novel method for 3d-printing curved open grid core sandwich structures using a thermoplastic extruder mounted on a robotic arm. This print-on-print additive manufacturing (AM) method relies on the 3d modeling software Rhinoceros and its parametric software plugin Grasshopper with Kuka-Parametric Robotic Control (Kuka-PRC) to convert NURBS surfaces into multi-bias additive manufacturing (MBAM) toolpaths. While several high-profile projects including the University of Stuttgart ICD/ITKE Research Pavilions 2014–15 and 2016–17, ETH-Digital Building Technologies project Levis Ergon Chair 2018, and 3D printed chair using Robotic Hybrid Manufacturing at Institute of Advanced Architecture of Catalonia (IAAC) 2019, have previously demonstrated the feasibility of 3d printing with either MBAM or sandwich structures, this method for printing Compound-Curved Sandwich Structures with Robotic MBAM combines these methods offering the possibility to significantly reduce the weight of spanning or cantilevered surfaces by incorporating the structural logic of open grid-core sandwiches with MBAM toolpath printing. Often built with fiber reinforced plastics (FRP), sandwich structures are a common solution for thin wall construction of compound curved surfaces that require a high strength-to-weight ratio with applications including aerospace, wind energy, marine, automotive, transportation infrastructure, architecture, furniture, and sports equipment manufacturing. Typical practices for producing sandwich structures are labor intensive, involving a multi-stage process including (1) the design and fabrication of a mould, (2) the application of a surface substrate such as FRP, (3) the manual application of a light-weight grid-core material, and (4) application of a second surface substrate to complete the sandwich. There are several shortcomings to this moulded manufacturing method that affect both the formal outcome and the manufacturing process: moulds are often costly and labor intensive to build, formal geometric freedom is limited by the minimum draft angles required for successful removal from the mould, and customization and refinement of product lines can be limited by the need for moulds. While the most common material for this construction method is FRP, our proof-of-concept experiments relied on low-cost thermoplastic using a specially configured pellet extruder. While the method proved feasible for small representative examples there remain significant challenges to the successful deployment of this manufacturing method at larger scales that can only be addressed with additional research. The digital workflow includes the following steps: (1) Create a 3D digital model of the base surface in Rhino, (2) Generate toolpaths for laminar printing in Grasshopper by converting surfaces into lists of oriented points, (3) Generate the structural grid-core using the same process, (4) Orient the robot to align in the direction of the substructure geometric planes, (5) Print the grid core using MBAM toolpaths, (6) Repeat step 1 and 2 for printing the outer surface with appropriate adjustments to the extruder orientation. During the design and printing process, we encountered several challenges including selecting geometry suitable for testing, extruder orientation, calibration of the hot end and extrusion/movement speeds, and deviation between the computer model and the physical object on the build platen. Physical models varied from their digital counterparts by several millimeters due to material deformation in the extrusion and cooling process. Real-time deviation verification studies will likely improve the workflow in future studies.

summary The objective of this research project is to simulate and evaluate the effect of movement velocity and cognitive abilities on the visual perception of three groups of urban users: pedestrians, cyclists and car drivers.The simulation and analysis is based on the 3D Dynamic Visual Analysis (DVA) (Fisher-Gewirtzman, 2017). This visibility analysis model was developed in the Rhinoceros and Grasshopper software environments and is based on the conceptual model presented in Fisher-Gewirtzman (2016): a 3D Line of Sight (LOS) visibility analysis, taking into account the integrated effect of the 3D geometry of the environment and the variant elements of the view (such as the sky, trees and vegetation, buildings and building types, roads, water etc.). In this paper, the current advancement of the existing model considers the visual perception of human users employing three types of movement in the urban environment--pedestrians, cyclists and drivers--is explored.We expect this research project to exemplify the contribution of such a quantification and evaluation model to evaluating existing urban structures, and for supporting future human perception-based urban design processes.

summary This paper discusses the use of parametrization and digital fabrication in architecture proposing a shift from increasing the architect’s control over the final product (determinist paradigm), towards increasing users' interaction. It presents the design process of an experimental interactive object intended to meet the former discussion and test the limits and difficulties that might arise during the process. Such an object was developed by Lagear (UFMG), as a response to the exhibition Homo Faber: Digital Fabrication in Latin America, CAAD FUTURES 2015.

title Integrating CFD and VR for indoor thermal environment design feedback
doi https://doi.org/10.52842/conf.caadria.2016.663
source Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 663-672
summary In the context of environmental consideration and im- provement of living standards, design of high performance buildings that are both comfortable and energy saving is important. Simulation tools (such as CFD) enables analysing and visualizing environmental factors (such as temperature and airflow) based on the design proper- ties and can be used to improve the building design for better perfor- mance. However, these tools have limitations in providing interactivi- ty with users for creating multiple CFD visualization results to be used for analysing design options. This research presents an integrated de- sign tool which consists of CFD and VR technologies. The proposed system visualizes CFD results in a VR environment together with ar- chitectural design. Additionally, it enables configuring CFD parame- ters within the VR environment and allows repeatedly executing simu- lation and visualizing updated results. The proposed system enables visualizing information in relationship with the actual architectural design, space configuration and thermal environment, and provides ef- ficient design feedbacks.

title From Bones to Bricks: Design the 3D Printed Durotaxis Chair and La Burbuja Lamp
doi https://doi.org/10.52842/conf.acadia.2016.318
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. 318-325
summary Drawing inspiration from the variable density structures of bones and the self-supported cantilvers of corbelled brick arches, the Durotaxis Chair and the La Burbuja lamp explore a material-based design process by responding to the challenge of designing a 3D print, rather than 3D printing a design. As such, the fabrication method and materiality of 3D printing define the generative design constraints that inform the geometry of each. Both projects are seen as experiments in the design of 3D printed three-dimensional space packing structures that have been designed specifically for the machines by which they are manufactured. The geometry of each project has been carefully calibrated to capitalize on a selection of specific design opportunities enabled by the capabilities and constraints of additive manufacturing. The Durotaxis Chair is a half-scale prototype of a fully 3D printed multi-material rocking chair that is defined by a densely packed, variable density three-dimensional wire mesh that gradates in size, scale, density, color, and rigidity. Inspired by the variable density structure of bones, the design utilizes principal stress analysis, asymptotic stability, and ergonomics to drive the logics of the various gradient conditions. The La Burbuja Lamp is a full scale prototype for a zero-waste fully 3D printed pendant lamp. The geometric articulation of the project is defined by a cellular 3D space packing structure that is constrained to the angles of repose and back-spans required to produce un-supported 3D printing.

summary This paper presents the research completed in AA Greece Visiting School 2016 in Thessaloniki. The work integrates computational design and digital fabrication, focusing on aspects of complexity in the making of an architectural interactive prototype. During this research, the use of computation accommodates the design and fabrication of indeterminacy and complexity in different scales and levels . The prototype, Eos, projects on itself the urban characteristics of the city of Thessaloniki. The aim has been to enable a 1-to-1 scale structure to act as a hub of information, capable of communicating with human users through interaction. As the city of Thessaloniki is characterised by specific environmental and urban conditions, the prototype has been set to express such properties.

title An Intuitive Heritage Education System for Learning Architectural Structures and Styles - Focusing on the historical Korean architectures
doi https://doi.org/10.52842/conf.ecaade.2016.2.529

summary Although national and international attention toward the cultural heritage is on a rise, there is a lack of public attention toward cultural heritage sites. One of the main problems is the lack of interaction and the visualization of cultural heritage on the sites. Especially Korean historical architectures are structurally complex and are not easily understood by common people. To improve the public awareness of architectural heritages, we propose a model-based diagnosis system to educate the visitors and tourists. The system is designed to guide the users to model an appropriate architecture in accordance with the era, location, and the usage. For the system, we built a robust set of cases based on the ontological structure we designed especially for architectural heritage education. It basically enables users to reconstruct buildings intuitively in six steps from bottom to top. A system evaluation was conducted on the affective, cognitive, operative aspect of the system at a heritage site. The results show well in terms of cognitive aspect but was evaluated poorly in terms of the operative aspect.

title A Simple System for Complex Mass Housing Design Collaborations - A system development framework
doi https://doi.org/10.52842/conf.ecaade.2016.2.137
source Herneoja, Aulikki; Toni Österlund and Piia Markkanen (eds.), Complexity & Simplicity - Proceedings of the 34th eCAADe Conference - Volume 2, University of Oulu, Oulu, Finland, 22-26 August 2016, pp. 137-146
summary Through the lens of participatory mass housing the paper explores the conference theme of simplicity and complexity. A suitable home is a deep rooted desire in the heart of people, and everyone has their own vision of what is a suitable home. Yet the multi-faceted social needs of housing and how they are being designed and developed in mass housing buildings appear too complex and appear too costly that the process would involve direct user participations. The authors have developed a Computer Aided Participatory Housing Design System (CAPHDS) to allow end users (future occupants) become active stakeholders in the design process with the aid of computational design instruments. These tools allow end users to actively engage in the process. The paper describes how a mass housing design process can be broken down into a set of simple tasks that encourage the active engagement and joint development of end users and architects with the proposed design.
