title	Dynamic 3D-Sketching
source	Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 107–116

summary	Sketching by hand is without doubt – alongside building models – the most common tool that architects employ when designing. A disadvantage of the sketch is, even if it is a perspective drawing, that it is a purely two-dimensional planar representation of a three-dimensional product: the three-dimensional impression that the sketch communicates is a product of the viewer’s imagination. Digital modelling tools on the other hand support the creation of three-dimensional content but fall short in their ease of handling: their complexity and potentially unintuitive operation hinder rather than support the design process. Taking this discrepancy as a starting point, the presented system details the development and prototypical implementation of a dynamic 3D-sketching tool. The underlying core idea is to create a seamless connection between a perspective hand-sketch and the corresponding digital 3D-model in order to benefit from the advantages of hand sketching as a design tool and computer maintained 3D models. The system allows the designer to work as usual, visualizing his or her thoughts using perspective sketches. The user sketches on a touchscreen surface. The 2D drawing is automatically interpreted and converted into a system of 3D lines, surfaces and volumes in real-time.

summary	Parametric design models enable the production of dynamic form, responsive material assemblies, and numerically and geometrically analytical feedback. The value potential for design produced through the procedural transformation of input parameters (or features) through algorithmic models has been repeatedly demonstrated and epistemically refined. However, despite their capacity to improve productivity and iteration, parametric models are nonetheless prone to inflexibility and reduction, both of which obscure processes of invention and discovery that are central to an effective design practice. This paper presents an experimental approach for the application of multiple, parallel computational design modelling strategies which are tested in the production of an inter-scalar model array that synthesises design intent, the simulation of material behaviours, performance-driven adaptation, and open-ended processes of discovery and categorical description. It is particularly focused on the computational potentials embedded in interdependent applications of simulation and machine learning algorithms as generative and descriptive drivers of form, performance, and architectural quality. It ultimately speculates towards an architectural design modelling method that privileges open model topologies and emergent feature production as critical operators in the generation of flexible and adaptive design solutions.

summary	Light as a multi-dimensional design element has fundamental importance for a sustainable environment. The paper discusses the need for an integration of scientific, technical and creative approaches to light and presents theory, methods and applications toward fulfilling this need. A theory of design developed from three experiments show how distinct qualitative and quantitative criteria in different disciplinary traditions can be integrated successfully, despite disparate technical/scientific, social scientific and art/humanities backgrounds. The model is applied to a pedagogical curriculum in the context of multi-level learning competencies.

title	Printing Compound-Curved Sandwich Structures with Robotic Multi-Bias Additive Manufacturing
source	Proceedings of the 2023 DigitalFUTURES The 5st International Conference on Computational Design and Robotic Fabrication (CDRF 2023)
doi	https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_44
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 city of Vienna follows a long-term initiative to become a Smart City. Within 2050 it aims to reduce 80% of the CO2 emissions (in comparison to 1990) and looks forward to generate ways for a sustainable energy production. (Smart City Framework Strategy 2014) Reaching this targets requires a complex planning process which involves interdisciplinary stakeholders and decision makers. An interactive multi-dimensional environment, comprising spatial objects and data models, is a helpful tool during these planning processes. This paper proposes a suitable path for the development of a structural framework for such an environment. The benefits of such an environment are shown in detail, based on an application of the economic solar heat potential in Vienna.

title	The BIM based Responsive Environmental Performance Design Methodology

summary	The concept of “families” lies in the core of internal data structure in Building Information Modeling (BIM). The elements of this modeling platform are all associated with each other as parts of the “families”, independent of their geometrical structure, materiality, parametric dependencies or their physical connection to other elements. Through the associations introduced among the parameters of the ‘families’ members, this study aims at establishing a methodology for a multi-objective evaluation of the environmental performance of the building as an organism. The methodology is founded on a system of different values and weights attributed to the parameters of the families members which are adjusted and fine-tuned through a series of iterations, thus affecting the overall building performance towards an optimum goal. The performance evaluation method used in the “families” methodology is not limited to the individual assessment of the environmental performance objectives or to an integrated multi-objective weighting mechanism; as an overall evaluation platform it checks and balances the individual characteristics of the system not as static conclusive results but as dynamic criteria intended to guide the overall design and building process. The importance of this paper lies in the construction of a concrete methodological set of tools for the assessment of the environmental performance of the building. It will lead the way in independent research in the field of architectural design and the development of ecological thinking and building in China.

summary	Building energy performance assessments are complex multi-criteria problems. Appropriate tools that can help designers explore design alternatives and assess the energy performance for choosing the most appropriate alternative are in high demand. In this paper, we present a newly developed integrated parametric Building Information Modeling (BIM)-based system to interact with cloud-based whole building energy performance simulation and daylighting tools to optimize building energy performance using a Multi-Objective Optimization (MOO) algorithm. This system enables designers to explore design alternatives using a visual programming interface, while assessing the energy performance of the design models to search for the most appropriate design. A case study of minimizing the energy use while maximizing the appropriate daylighting level of a residential building is provided to showcase the utility of the system and its workflow.

summary	Typical horizontal building types, open spaces, and human activities have yet to competently overcome or adapt to the constraints of vertically-oriented dense urban environments. Designing the built environment to the oblique, or more than two axes at once, is a required strategy for the future of city planning, the advancement of body-space interaction in architecture, and to reinforce the interconnectedness of the natural environment with human activities. With the development and increasing use of 3D modeling software, parametric and generative design processes, and the progressive investigation of complex geometry, it is likely that the oblique will be envisioned more and more as a functional architectural device. This research investigates the tessellation of minimal surface geometry to achieve a folded, multi-use surface capable of connecting disparate urban program and which can enable a city to offer amenities that are typically available in horizontally-oriented suburbs. The geometric family of the helicoid is found as the optimal formal generator because of its ability to create a continuous surface while allowing for both horizontal and vertical circulation.

summary	When working on urban planning projects there are usually multiple aspects to consider. Often these aspects are contradictory and it is not possible to choose one over the other; instead, they each need to be fulfilled as well as possible. Planners typically draw on past experience when subjectively prioritising which aspects to consider with which degree of importance for their planning concepts. This practice, although understandable, places power and authority in the hands of people who have varying degrees of expertise, which means that the best possible solution is not always found, because it is either not sought or the problem is regarded as being too complex for human capabilities. To improve this situation, the project presented here shows the potential of multi-criteria optimisation algorithms using the example of a new housing layout for an urban block. In addition it is shown, how Self-Organizing-Maps can be used to visualise multi-dimensional solution spaces in an easy analysable and comprehensible form.

title	Adaptive [skins]: Adaptation through smart systems
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 275-289
summary	The project investigates responsive building skin systems that adapt to the dynamic environmental conditions to regulate internal conditions in a habitable space over different periods of time by exhibiting a state of motion and dynamism. Passive and active building skins are developed using shape memory alloys and pneumatic actuators through investigations of smart systems that integrate smart materials and smart geometries. Nitinol springs are integrated in tensegrity systems to actuate the adaptive behaviour, which forms the passive roof system. Owing to the complexity of the multi-parametric system, genetic algorithms are developed for system optimization and calibrated with physical prototypes at varied scales. The developed systems are tested against two distinct climatic models- New Delhi and Barcelona, and evaluated for performance, based on heat and light, which are quantified as solar gain and illuminance as principles, and daylight factor for evaluation purpose. New tool-sets are developed in the process by combining various digital tools, to create a real-time feedback and memory loop system.

summary	This paper explores the development and application of informed multi-agent systems (IMAS) as a means of programming spaces generated through the subtraction of built form at both urban and architectural scales. We argue that IMAS are distinct from multi-agent systems (MAS) due to their adeptness at responding to and conditioning complex, data-rich territories that require an open program while also benefiting from top-down constraints that delimit the system’s edges.

summary	This paper introduces a new spatial analysis methodology based on visibility graphs. Through various design elements architects can create configurations where our visual field and the relations of spaces can be challenged in a combinatorial game beyond the easily accessible and understandable boundaries of the environment. This research explores the trans-spatial architectural elements, transparencies and projected realities that playfully challenge visibility, permeability and accessibility in built environment. The paper presents the computational problem of analysing spaces that include 'augmented visibilities' and areas with 'inaccessible but visible' locations, where dislocated multi-dimensional overlaps frequently occur. Furthermore, proposes a new 'mixed-directionality graph structure' and the definition of 'Augmented Visibility Graph Analysis' (AVGA) as a new spatial analysis methodology. AVGA overcomes limitations of current visibility graph analysis theories and allows the analysis of architectural and urban space that includes visuo-spatial overlaps, hybrid configurations and multi-dimensional information. Finally, a series of mathematical graph analysis measures and test cases associated with observations and experimental data from real spaces is presented in order to demonstrate AVGA.

summary	Luminance contrast has been identified as an effective depth cue through perceptual studies using digital images generated by the integrated technologies of physically based lighting simulation and perceptually based tone mapping. However, the prior established framework utilizes a single camera viewpoint, failing to address the binocular vision of the human visual system. In this study, the computational framework is extended to incorporate 3-dimensional (3D) stereo display technology. Psychophysical experiments were conducted to investigate the depth effect of luminance contrast on the experimental scenes presented on conventional and stereo displays. The objective of this study was twofold: first, to investigate the effect of luminance contrast on depth perception, considering binocular vision; second, to further advance the visual realism of the computer-generated environment to reflect the perceptual reality of static pictorial and binocular disparity cues.

title	Towards a dynamic evacuation system: developing methodologies to simulate the evacuation capabilities of subway stations in response to a terrorist attack with CBRNE weapons
source	Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 1, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 109-118

summary	Events in recent times have highlighted the vulnerability of underground public transportation to possible terrorist attacks. A key question therefore is how an evacuation can be accomplished from underground stations safely. The strategy “go up and take the nearest exit to the surface” might not be the best response. Evidence from the Daegu subway station fire in 2003, investigated by Tsujimoto (2003) and Jeon and Hong (2009) establish that smoke or toxic airborne substances from a terrorist attack tend to use the same direct routes used by the fleeing passengers and as result significant injuries or fatalities can occur. This study proposes the concept of a dynamic evacuation system which would guide subway users along safe routes. To test how this system may operate, the study discussed combines measurements from tracer gas experiments with climate measurements to establish how toxic agents spread in subway stations under certain conditions and combines these results with those from pedestrian simulations applied to calculate evacuation times for possible escape routes. By integrating the resulting dataset from these methods, an evidence base of how a dynamic evacuation system may work can start to form.

title	An Adaptive Decision-Making Framework for Designing Material Behaviours

summary	This paper describes an adaptive decision-making design framework for investigating the synergies between aesthetically-driven and performance-driven criteria, specifically in designing the material behaviour of an electroresponsive building envelope system. An immersive and interactive simulation environment developed in the C++ programming language provides a computational tool for testing the visual and energetic performance of a dynamic building envelope as it negotiates bioclimatic energy flows with participants’ aesthetic preferences and interactions. Experiments in bioresponsive feedback loops examine the impacts that user engagement and real-time energy performance feedback have on participants’ design choices. Preliminary results demonstrate that exposure to energy performance feedback and to the collective design choices of multiple users leads to adaptive decision-making that favours synergistic system performance with the potential for increased socio-ecological connections. Critically, this research provides new methods for supporting the design of emerging material behaviours for dynamic building envelopes that can negotiate multiple performance criteria.

summary	Building designers make decisions in early design stages that have large impact on building performance, including those of energy-, daylight- and indoor environment performance. Building performance simulation (BPS) tools can support the designer, in making better decisions, by providing the performance consequences of design choices. However BPS tools often require deep technical knowledge and is too time consuming to use to effectively support the design exploration in the early design stages. To solve this challenge, the current paper proposes: Sentient building performance simulation systems, which combine one or more high precision BPS tools to provide near instantaneous performance feedback directly in the design tool. Sentient BPS systems are essentially combining: 1) design tools, 2) parametric tools, 3) BPS tools, 4) dynamic databases 5) interpolation techniques and 6) prediction techniques as a fast and valid simulation system for the early design stage.
