summary	In continuation to the Deceptive Landscape Installation research project (Agkathidis, Kocatürk 2014), this paper investigates the implementation of generative design techniques in undergraduate architectural design education. After reviewing the main definitions of generative design synoptically, we have assessed the application of a modified generative method on a final year, undergraduate design studio, in order to evaluate its potential and its suitability within the framework of a research led design studio, leading to an RIBA accredited Part I degree. Our research findings based on analysis of the design outputs, student performance, external examiners reports as well as student course evaluation surveys indicate a positive outcome on the studio's design approach, as well as its suitability for an undergraduate design studio. They initiate a flourishing debate about accomplishments and failures of a design methodology, which still remains alien to many undergraduate curricula.

title	Progeny: A Grasshopper Plug-in that Augments Cellular Automata Algorithms for 3D Form Explorations

summary	Cellular automata (CA) is a well-known computation method introduced by John von Neumann and Stanislaw Ulam in the 1940s. Since then, it has been studied in various fields such as computer science, biology, physics, chemistry, and art. The Classic CA algorithm is a calculation of a grid of cells' binary states based on neighboring cells and a set of rules. With the variation of these parameters, the CA algorithm has evolved into alternative versions such as 3D CA, Multiple neighborhood CA, Multiple rules CA, and Stochastic CA (Url-1). As a rule-based generative algorithm, CA has been used as a bottom-up design approach in the architectural design process in the search for form (Frazer,1995; Dinçer et al., 2014), in simulating the displacement of individuals in space, and in revealing complex relations at the urban scale (Güzelci, 2013). There are implementations of CA tools in 3D design software for designers as additional scripts or plug-ins. However, these often have limited ability to create customized CA algorithms by the designer. This study aims to create a customizable framework for 3D CA algorithms to be used in 3D form explorations by designers. Grasshopper3D, which is a visual scripting environment in Rhinoceros 3D, is used to implement the framework. The main difference between this work and the current Grasshopper3D plug-ins for CA simulation is the customizability and the real-time control of the framework. The parameters that allow the CA algorithm to be customized are; the initial state of the 3D grid, neighborhood conditions, cell states and rules. CA algorithms are created for each customizable parameter using the framework. Those algorithms are evaluated based on the ability to generate form. A voxel-based approach is used to generate geometry from the points created by the 3D cellular automata. In future, forms generated using this framework can be used as a form generating tool for digital environments.

title	An Adaptive Decision-Making Framework for Designing Material Behaviours
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. 55–64
doi	https://doi.org/10.52842/conf.caadria.2014.055
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.

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.

title	Temporary Architecture: An urban mirage
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. 405-413
summary	One of the emerging multidisciplinary contemporary art practices is interactive installation art, which is concerned with constructing a temporary artistic environment that is digital, responsive and engaging. It is usually displayed within existing architectural context whether indoor in a gallery space or outdoor in a public space. Recent examples of such art projects show that interactivity and illusion are effectively present and highly influential in the perception and memory of the place. A digital display on a building façade can remain attached to the history of the site in the spectator’s memory even after the display is removed. An interactive space that involves body response and emotional sensory interaction can determine the narrative perceived from the experience. These trends seemingly bring together the physical context and the digital space to contain the spectator. The two mediums are merged to provide a new genre of space, hence a new mode of perception where the art space mediates people’s movement and overlay the context with new meanings. Multiple backgrounds are involved in the creative process of interactive installation art, all of which involve examining various concepts through artistic engagement with temporary spaces. Here, particularly because of interactivity and immerseveness, the spectator becomes part of the performance (the subject); with his moving and reacting he activates the narrative and probably gives it its shape. This paper aims to explore the potentials of the digital spatial display to enhance or weaken our sense of belonging to the surrounding environments while creating an illusionary space within the real physical one. It also aims to discuss how this influence would affect the memory of the mixed experience; the installation being digital, temporary and illusive and the space being physical, permanent and real. What happens to the “spectator” when contained by the digital-interactive and the physical medium(s)?. In order to unfold the mentioned questions, the study uses theories of perception and performance reflected on live case studies of recent art projects where the researcher becomes a member of the audience and an observer at the same time in order to trace the journey inside this new medium. In an era where time is being more difficult to grasp and identities of visual culture is becoming more difficult to define, temporary responsive environments can provide some openings where space becomes durational, yet, influential, and where people’s movements become more meaningful in the visual terrain.

title	Urban body network configurations - Attica

summary	The methodology presented here is grounded on the reconstruction of the urban body as a network configuration consisting of material and non-material components (Bateson, 1972). It is based on the assumption that if one can describe the rules that define the nodes and the connections of the network construction/urban body, as well as their attributes, then the differentiation on the relationships between elements, or even a shift from one value to another, would result in different network constructions, that would produce a time-based sequence of the self-adaptational and self-organizational reconfigurations occurring during the mutational procedure. The urban body is defined as the part of the urban tissue which distinguishes itself from the whole of the urban landscape, either because of constructed boundaries, or because of the strengthening of a specific attribute, which would result in a kind of an immaterial boundary, or, in other words the formation of an identity.

summary	Current parametric design software lacks the capacity to integrate simulation and optimisation when they would be most relevant: at the early stages of the design process. This paper presents a novel framework to address this issue: A parametric program that supports performance-based modelling by integrating detailed physical simulation modules that also take construction issues into account, while at the same time providing easy access to high-level optimisation approaches. Providing bidirectional parametric modelling capabilities, we refer to the system under development as augmented parametrics. It is being developed as part of a research project sponsored by the Austrian Science Foundation.

summary	Human imagination has played with the idea of an alternative technological world for years. From dystopian proposals like Neuromancer or The Matrix to more positive views like the recent Upload series, the exploration of the friction between the digital world and the physical world has entertained the imagination of our society for decades. Outside the fictional environments, the omnipresence of the internet and the development of “the cloud” are showing that the virtual world is possible and that the idea of a Metaverse is no longer part of science fiction but a very real future for human relations (Winters 2021). In line with the idea of the Metaverse, the intersection of the virtual and the physical world is being explored through the idea of Extended Realities. Technology is allowing humans to enhance their capabilities more than ever, and in fact, it has been proposed that we are entering the Augmented era (King 2014). This paper explores the opportunities and possible challenges that “Extended Architecture” has by analyzing a research project based on augmented reality as the media to explore these ideas. This project will propose a speculative approach to how the fact that in the recent future, everyone will have access to an AR device will change the way we perceive and understand our architectural environment.

summary	This paper presents a system that allows immersive visualizations to become a natural and integrated part of the current building design process. It is realized through three main components: (1) the Oculus Rift - a new type of Head Mounted Display (HMD) directed at the consumer market, (2) a real-time rendering engine supporting large Building Information Models (BIM) that is, (3) implemented as a plug-in in a BIM authoring software. In addition to provide details regarding the implementation and integration of the different components in our system, we present an evaluation of it from three different perspectives; rendering performance, navigation interface and the ability to support fast design iterations.

title	Integrated Generative Technique for Interactive Design of Brickworks
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. 49-64
summary	Bricks have been used in the construction industry as a building medium for millennia. Distinct patterns of bricks depict the unique aesthetic intentions found in Roman, Gothic and Islamic architecture. In contemporary practice, the use of digital tools in design has enabled methodologies for creating new forms in architecture. CAD and BIM systems provide new opportunities for designers to create parametric objects for building form generation. In masonry design, there exists an inherent contradiction between traditional patterns in brick design, which are formal and prescribed, and the potential for new patterns generated using design scripting. In addition, current tools do not provide interactive techniques for the design of brickwork patterns that can manage constant changes parametrically, to inform and influence design process, by providing design feedback on the constructive and structural aspects of the proposed brick pattern and geometry. This research looks into the parametric techniques that can be applied to create different kinds of patterns on brick walls. It discusses a methodology for an interactive brickwork design within generative techniques. By integrating data between two computational platforms – the first based on image analysis and the second on parametric modeling, we demonstrate a methodology and application that can generate interactive arbitrary patterns and map it to the brick wall in real-time.

summary	The method proposed in this paper addresses the management of values and the cost estimate, based on target costing approach, and integrated with Building Information Model (BIM). This design method must incorporate mechanisms of automated assessment associated with desired value at cost during the design process. The paper will try to show, in brief, that there is a real possibility of inclusion of methodological tools of design, allowing assessment of values in real time during the design actions.

summary	The evaluation of a low-tech wind sensing platform for urban aerodynamic simulations relevant to pedestrian comfort. In this paper, the wind canyon effect is simulated with two different building morphologies. The platform provides conceptual knowledge of the dynamics in wind relevant for designers, architectural practitioners and students of design. Low-cost hot wire anemometry is utilised for the design of an Experimental Fluid Dynamic (EFD) wind sensing network interface. This paper explores the validity of the sensing platform for a new approach for non-wind engineers to gain a better understanding of the dynamics of wind. The influence of real-time feedback from quantified wind on the understanding of wind phenomena for non-wind engineers is discussed and compared with post analysis data. It was found that real-time quantified feedback from wind intrigues and stimulates the intuitive notion of wind dynamics through discussion, however post analysis remains critical to evaluate building design performance.

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	Since Building Information Modelling as a technology depends on recognizing parts of the buildings as objects that can be simulated digitally, to prepare students to grasp the BIM way of thinking, educators can start introducing the concept early in the architectural curriculum without using the real tools. The researchers monitored the students' progress over a period of time while they were using different 3 dimensional CAD tools in several situations such as design studio visualization and construction document production until eventually the same group of students have been introduced formally to a real BIM tool. The research tries to establish a relationship between the pedagogical techniques and the success of the students to grasp what BIM is about and the development of their ability to use it fruitfully. Comparisons between their performances should shed the light on the best method to use in order to prepare students for the use of BIM.

summary	This ongoing research describes a feedback loop procedure where physical inputs are used as the medium for offline robotic simulation. The purpose is to investigate the ability of industrial robots that are currently used in manufacturing processes to work in a flexible and productive manner whilst providing a continuous feedback loop between physical inputs and fabrication artifacts. In order to achieve this, a methodology is developed that involves the use of data acquisition devices to enable the transference of information from the physical to the digital environment and then to use this data as real-time parameters to control the robot's behaviour during fabrication. The aim is to achieve active involvement of robots in the manufacturing process to address complex construction issues and to ensure accuracy, a reduction in manufacturing defects and flexibility in the materials used. This investigation is accompanied by relevant experiments to exemplify the potential of control mechanisms to be used in prototyping case studies.

summary	This paper introduces a counter-mapping attempt augmented by a Geoweb 2.0 platform in the context of two Belgian inner-city neighborhoods. The two aims of this project were to build a platform for the collective construction of a better understanding this dynamic super-diverse arrival environment and bring the various qualities and aspects of these super-diverse urban neighborhoods to foreground. In this study we report on the first results of this project which took place in Ghent and Brussels in 2014. Around 300 architecture students registered, interpreted and geocoded visible signs along preconceived tracks by means of a Geoweb 2.0 platform. Through field observations and interviews, the students created dynamic and interactive maps. We found that the large-scale mapping through Geoweb 2.0 makes it possible to discern different layers of use in arrival neighborhoods. These layers referred to different population groups which continuously have to negotiate each other's presence. Furthermore, the platform created the possibility to effectively and efficiently combine student fieldwork with online and offline lectures and offered students the opportunity to comment on, peer-review and learn from each other's insights. The findings will serve as an alternative information resource in the forthcoming Master's thesis graduation design studio which will be led by the first author.

title	A Thousand BIM: A rapid value-simulation approach to developing a BIM tool for supporting collaboration during schematic design
source	International Journal of Architectural Computing vol. 12 - no. 1, 47-60
summary	The purpose of this study is to develop a BIM-based plug-in that is able to assist a collaboration among heterogeneous professionals. The tool will enable them to communicate in the same language, articulate criteria and priorities in multiple perspectives, and to share rapidly simulated evaluations of schematic design variations. Among many barriers that block collaborations among professionals, a quintessential barrier in the building and design industries may be epistemological rather than physical. The professionally different ways of thinking, expertise, values, and priorities can be a block on the collaborative development process of architectural design projects. This paper takes the example of the relationship between developers and architects, who tend to have different evaluation criteria. A real-time value simulation tool is introduced as a means to generate possible building typologies on a given project site, with computation of expected total values expressed in simple financial terms.

summary	Key parameter of a reasoning process supporting real time performance is the use of active heuristics that facilitate the achievement of goals in a timely manner (Dodiawala et al. 1989). A real time approach should incorporate speed, timeliness and adaptation during the execution of tasks. Speed and efficient knowledge processing are addressed for the solution of complex building engineering problems, such as the calibration of Building Energy Models (BEM) to the actual performance data. During retrofit projects, calibrated BEM models aid the design process, and provide a solid base for performative assessments. Despite the demand for building performance evaluations, BEM calibration remains a work-intensive task (Lam et al. 2014). This study proposes a time efficient framework for BEM calibration input data management based on the methodology of a blackboard artificial intelligence knowledge processing system. The resulting model was used for sequential data mining for the energy assessment during the renovation of a commercial building.

title	Approximating Computational Fluid Dynamics for Generative Tall Building Design
source	International Journal of Architectural Computing vol. 12 - no. 2, 155-178
summary	Background literature review, methodology, results, and analysis are presented for a novel approach to approximating wind pressure on tall buildings for the application of generative design exploration and optimisation.The predictions are approximations of time-averaged computational fluid dynamics (CFD) data with the aim of maintaining simulation accuracy but with improved speed.This is achieved through the use of a back-propagation artificial neural network (ANN) with vertex-based shape features as input and pressure as output.The training set consists of 600 procedurally generated tall building models, and the test set of 10 real building models; for all models in both sets, a feature vector is calculated for every vertex. Over the test set, mean absolute errors against the basis CFD are 1.99–4.44% (_:2.10–5.09%) with an on-line process time of 14.72–809.98s (0.028s/sample). Studies are also included on feature sensitivity, training set size, and comparison of CFD against prediction times. Results indicate that prediction time is only dependent on the number of test model vertices, and is therefore invariant to basis CFD 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.
