summary	Advancements in robotic fabrication are enabling on-site construction in increasingly larger scales. In this paper, we argue that as autonomous tools encounter the territorial scale, they open new ways to embed information into it. To define the new practice, this paper introduces a protocol combining a theoretical framework and an iterative process titled Informing Grounds. This protocol mediates and supports the exchange of knowledge between a digital and a physical environment and is applicable to a variety of materials with uncertain characteristics in a robotic manufacturing scenario. The process is applied on soil and demonstrated through a recent design-to-fabrication workshop that focused on simulating digital groundscaping of distant lunar grounds employing robotic sand-forming. The first stage is ‘sampling’—observing the physical domain both as an initial step as well as a step between the forming cycles to update the virtual model. The second stage is ‘streaming’—the generation of information derived from the digital model and its projection onto the physical realm. The third stage is ‘transforming’—the shaping of the sand medium through a physical gesture. The workshop outcomes serve as the basis for discussion regarding the challenges posed by applying autonomous robotic tools on materials with uncertain behavior at a large-scale.

title	Agency of Interactive Architecture in socio-technological relationship through Actor-Network Theory
source	Ji-Hyun Lee (Eds.) "Hello, Culture!" [18th International Conference, CAAD Futures 2019, Proceedings / ISBN 978-89-89453-05-5] Daejeon, Korea, p. 102
summary	With fast development of new technologies built environment transitioned from a silent background of activities performed by users to another participant of those activities. Agency of interactive architecture is based on interpretation of input data, like users’ actions, their response to the spatial agency, data from environment or other actors, and changing its performance accordingly. Architectural components, environmental conditions and people are all treated as agents and closely correspond to Actor-Network Theory (ANT). This theory generally aims to reveal the complexities of socio-technological world. ANT incorporates a principle of generalized symmetry, it means that human and nonhuman (artifacts, organization structures, etc.) actors are incorporated into the same conceptual framework and assigned equal level of agency. By analysis of the agency of Interactive Architecture through ANT the paper provides insight on social role of this new emerging type of space and its influence on other participants on socio-technological relationship.

title	Augmented Craftsmanship

summary	Over the past decade, we have witnessed rapid advancements on both practical and theoretical levels in regard to automated construction as a consequence of increasing sophistication of digital fabrication technologies such as robotics, 3D printing, etc. However, digital fabrication technology is often very limited when it comes to dealing with delicate and complex crafting processes. Although digital fabrication processes have become widely accessible and utilized across industries in recent times, there are still a number of fabrication techniques—which heavily rely on human labour—due to the complex nature of procedures and delicacy of materials. With this in mind, we need to ask ourselves if full automation is truly an ultimate goal, or if we need to (re)consider the role of humans in the architectural construction chain, as automation becomes more prevalent. We propose rethinking the role which human, machine, and computer have in construction— occupying the territory between purely automated, exclusively robotically-driven fabrication and highly crafted processes requiring human labour. This is to propose an alternative to reducing construction to fully automated assembly of simplified/discretized building parts, by appreciating physical properties of materials and nature of crafting processes. The research proposes a design-to-construction workflow pursued and enabled by augmented humans using AR devices. As a result, proposed workflows are tested on three prototypical inhabitable structure, aiming to be applicable to other projects in the near future, and to bridge the gap between purely automated construction processes on one hand, and craft-based, material-driven but labour-intensive processes on the other.

summary	Health is our wealth and we are rarely aware that the choice of living and working environment affects us. We spend most of our time in indoor environments so the quality of indoor air plays an important role in the maintenance of health and well-being. Moreover, Building Information Modeling (BIM) is emerging technology, which plays an essential role in collaboration among multi-discipline professions, time and cost saving, fabrication and construction as well as facilities management. However, it is not accepted by all planners yet. BIM could also offer a framework to help improving health and well-being of future users of the new building. The main aim of this paper is to monitor environmental and health impact data in BIM models to assure healthy living environments. First, the paper explores which environmental and health parameters could be measured in the indoor environment and which are already present in BIM models. Second, it explores options to expand BIM specifications to support monitoring environmental and health impact data in BIM models to assure healthy living environments.

title	Agent-driven Accessibility and Visibility Analysis in Nursing Units
doi	https://doi.org/10.52842/conf.caadria.2019.1.351
source	M. Haeusler, M. A. Schnabel, T. Fukuda (eds.), Intelligent & Informed - Proceedings of the 24th CAADRIA Conference - Volume 1, Victoria University of Wellington, Wellington, New Zealand, 15-18 April 2019, pp. 351-360
summary	This study investigates the nursing unit design for care quality and efficient operation, evaluating visibility and walking distance of nurses in the different form of layout. Sufficient visibility from nurses' station to patient rooms and corridors can increase nurses' care abilities to understand the needs and movements of patients. The workload and time caused by nurse's walking can be diverted to patient care. Isovist analysis and agent-based simulation are experimented to investigate the effects of spatial layout on visibility and nurses' accessibility to patients. In the isovist analysis, the nurses' station facing patient rooms were more effective in nurse-to-patient visibility. In the nurse's walking trail analysis, uneven walking distance of each nurse appeared due to the asymmetric patient room layout centering the nurses' station and heavy room allocation plan. Understanding the potential impacts of design parameters enables designers to predict possible behaviors in each design alternative and to make effective and efficient design decisions for the occupants. This study underlines the role of the physical environment in the delivery of patient care and nurse's well-being. It presents an evaluation framework integrating syntactic analysis and agent-based simulation to predict the effect of the spatial layouts on the hospital activities.

title	Comfort-Based Integrative HVAC System with Non-Intrusive Sensing in Office Buildings
doi	https://doi.org/10.52842/conf.caadria.2019.1.785
source	M. Haeusler, M. A. Schnabel, T. Fukuda (eds.), Intelligent & Informed - Proceedings of the 24th CAADRIA Conference - Volume 1, Victoria University of Wellington, Wellington, New Zealand, 15-18 April 2019, pp. 785-794
summary	Heating, ventilation and air-conditioning system plays a key role in shaping the built environment. The effective and efficient HVAC operations not only achieve energy savings but also create a more comfortable environment for occupant indoors. Since current HVAC systems with fixed schedules cannot guarantee the operation with high energy efficiency and provision of comfortable thermal environment for occupants, it is of great importance to develop new paradigm of HVAC system framework, especially in the open-plan office environment so that everyone could work under their preferred thermal environment. Moreover, compared to environment-related factors to thermal comfort, sensing systems for occupant-related factors such as clothing insulation, metabolic rate, skin temperature have not had standardized yet and most of sensing systems for occupant-related factors may either result in privacy issue or are too intrusive. Hence, it is necessary to develop a new non-intrusive and less private sensing framework for monitoring individual thermal comfort in real-time. Therefore, this paper proposes an integrative comfort-based personalized cooling system with the operation of the centralized systems in office buildings. The results show that such integrative and interactive HVAC system for workplaces has advantages over thermal comfort improvements and energy savings.

title	Digital Empowerment for the "Experimental Bureau" - Work Based Learning in Architectural Education
doi	https://doi.org/10.52842/conf.ecaade.2019.1.117

summary	This paper describes the concept of the "Experimental Bureau" as a didactic environment aiming to deal with real-life design tasks within the framework of architectural education. Its main focus lies on the specific opportunities for digital empowerment of students who learn about the design process - sometimes even in the role of contractors - in real-life oriented project work. Thus the following questions come under scrutiny and discussion from an angle of work based learning: What kind of design problems are tackled in a meaningful way by students through the utilization of a digital strategy? What kind of software (or software mix) is chosen and what problems are addressed by the choice and handling of these digital tools? These questions are answered in a different way applying the format of the Experimental Bureau, driven by its real-life projects and client communication, in comparison to largely artificial tasks confined to the academic realm.

title	Urban Street Retrofitting - An Application Study on Bottom-Up Design
doi	https://doi.org/10.52842/conf.ecaade.2019.3.287

summary	Urban streets will have to be retrofitted to improve walkability and to provide space for a diversity of transport modes. This paper introduces a framework which combines space syntax and shape grammars in a design support method for generating scenarios for urban street retrofitting. A procedure to hierarchize streets and select priority locations for urban street retrofitting is presented. Four different angular choice analyses with decreasing radii are used to derive the hierarchical structure of target urban areas with the aim of triggering shape grammar rules and generating bottom-up intervention designs. The same measure using a local radius to represent walking modal is then used to determine which streets should be retrofitted to improve pedestrian safety and walkability for the largest number of people. An application study using this procedure is presented and results are compared to street hierarchies from two different sources. This study is the first step towards automating the generation of design scenarios for urban street retrofitting.

summary	During the last years, insertion of technology accelerates its incursion both in the design process and in the teaching-learning process. Design education has gone through different visions: Some hold the vision of education in design with a look at professional training. Others, have chosen to study the roots and problems of the training process, the ultimate goal is to generate experts in future designers. An element that - consistently - is often absent from such discussions is the role played by prototypes in the teaching-learning process. This research reviews the role that the prototype has played, as a central element, in the process of collecting evidence, with a view to informing the decision making during the development of Project Design. The paper discusses the role that prototypes - from the standpoint of CoDesign, Evidence Design, and evolutionary design - have played in the teaching experiences of the last four semesters within a Computer Lab for students of Industrial Design. The systematization of information extracted from the research experiences has evolved from the Lab model to the Maker-space experience.

title	Socio-technical interactions in the relationship between social movements and internet: a review of the state of the art and the theoretical framework
source	SIGraDi 2020 [Proceedings of the 24th Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Online Conference 18 - 20 November 2020, pp. 549-554
summary	The paper recognizes the relationship between social movements and internet how new practices of resistance through technological appropriation (Castells, 2012). This social interaction mediated by technology, understood as socio-technical interaction, establish new dynamics between human-technology-human and other heterogeneous actants (Latour, 2008), such as power and counter-power institutions that also connect to the socio-technical network. Therefore, the studies about digital interaction of the instrumental line are expanded, towards an understanding of socio-technical interactions, from the dynamics of design/use interconnected with cultural, political and economic contexts (Scolari, 2004, 2019), because the technology must satisfy social needs.

title	Aesthetics in Computational Design - A reflection on Max Bense's theory on aesthetics of information and state of things.
doi	https://doi.org/10.52842/conf.ecaade.2019.2.855
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 2, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 855-862
summary	Current dominance of functionalist and performance related approaches to computational design and methods in architecture are investigated under the precondition of Max Bense's theory of aesthetic potential. Establishing Bense's taxonomy of aesthetic potential and applying it to selected computational methods the level of aesthetic potential within the different computational approaches is investigated. Frei Otto's soap bubble experiments serve as a reference to illustrate different levels of aesthetic potential. Bense's aesthetic potential, which lies not in the eye of the beholder but is immanent to the object itself as a property of the object, suggests that computational design systems synthesising objects based on rules or embedded constraints appear to either have little aesthetic potential or receive their aesthetic potential form the outside of the computational system, namely the interaction with the user. Evolutionary design systems appear to create objects or processes with a certain aesthetic potential within Bense's theoretical framework.

title	Parametric Urban Design from Concept to Practice
doi	https://doi.org/10.52842/conf.ecaade.2019.1.817
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 1, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 817-826
summary	Little research has been made into the application of parametric urban design approaches to urban design in practice. On the part of urban design practitioners, lack of knowledge of parametric design, time constraints and a focus on day-to-day operations contribute to this situation. And on the part of parametric design researchers, lack of understanding of practice workflows, project types and media output types also contribute. The limited interaction between academia and practice in itself constitutes a barrier to changing the situation. This paper presents some first results from a research project aiming to overcome this barrier. The research design involves a theoretical framework for parameterising site design on the level of site layout, building forms and facade schemas. It also involves an analysis of typical workflows from urban design practice, as well as of the types of media which are typically used to present urban design projects.

title	A Decision Support Framework for FLP in the Context of Industrial Facilities by the Use of BIM
doi	https://doi.org/10.52842/conf.ecaade.2019.2.269
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 2, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 269-278
summary	In today's industrial production environment, an effective solution to the FLP (Facility Layout Problem) plays a significant role in deciding whether a facility will hold a competitive advantage against others by its improved workflow. This advantage comes from an efficient placement of facilities, which mostly contributes to the overall business performance. In addition to that, regarding the need to answer the demands of the dynamic market, facilities need to adapt their processes and adapt their production line as quickly as possible. Therefore, a continuous search for a solution to the FLP is present. Although there are many space allocation programs available both as academic and commercial products, present approaches' availability in the BIM environment is not common yet. This paper introduces a decision support system framework which uses Non-Dominated Sorting Genetic Algorithm-II (NSGA-II) to generate the most appropriate solution in Revit Dynamo environment both in the earlier phases of design and through the life-cycle of the facility. The proposed framework will specifically be responsible for generating solutions for equipment location in serial production facilities. As NSGA-II is a Multi-Objective Evolutionary Algorithm (MOEA), a second optimization criterion is defined as the optimization of the foreman's locations distributed on the shop floor. A Dynamo package named Refinery will hold the optimization and evaluation procedures.

summary	This paper presents arguments and experiences around generative design applied to housing, combining the potential of computational tools with an agenda to increase internal differentiation. It argues for a more varied and mixed approach to the clustering of apartment types and building typologies to increase the social diversity within projects and in relation to this, the sustainability and resilience of urban environments towards future societal changes. Through the discussion of two residential projects operating at different scales, it is shown how carefully calibrated complexity can be introduced in the design process, communicating with clients and collaborators and keeping the complexity of the workflow minimised. It is argued that this avenue of work points to significant opportunities to rethink how computational architectural and urban design processes can be linked to social sciences and a more human-centred approach within the understanding of performance of the built environment.

summary	Creating workplace seating plans is currently a laborious task carried out based on intuition with potentially suboptimal outcomes. A data informed seating plan generator could see an increase in organizational success metrics. In this paper, we present a modular framework for using a social network, a spatial network, and an organization objective to generate data-informed seating plans for a design firm. In addition, an open-source tool was created to allow individuals in an organization to evaluate prospective arrangements. This implementation gave employees more agency by informing their seating decisions as well as the ability to better inform their intuitions about seating arrangements.

title	Surrealist Aesthetics in Second-Order, Cybernetic Architecture

summary	In experimental architecture and during the last decade, second-order cybernetic systems (SOCA) have been broadly explored. Under this umbrella, the implementation of robotics and machine learning in recent experimental projects has impacted academia through new fabrication strategies, new design methods, and new adaptive devices. This paper presents a theoretical approach to the aesthetic side of this impact. In particular, it argues that SOCA rearticulates Benjamin’s concept of “distracted perception” through three structural principles of Surrealism: the emphasis of presentation over representation; the centrality of the notion of automatism; and the simultaneous management of closeness and distance. Each alignment is doubly articulated. First it establishes a comparison between Surrealist artwork from the first half of the 20th century and three SOCA projects in which the notion of autonomy and ubiquity are crucial. Second, it evaluates the impact on Benjamin’s notion of “distracted perception.” The paper concludes that the Surrealist aesthetic structures analysed in SOCA differ from traditional Surrealism in the replacement of an inner and unconscious other by an outer and algorithmic other. Its presence simultaneously expands and contracts Benjamin’s architectural understanding of “distracted perception,” a double movement whose perception paradoxically occurs under the single framework of Benjamin’s haptic vision.

title	Space Semantics - An investigation into the numerical codification of space

summary	"Space-Semantics" is a computational design proposition that interrogates how architectural spaces can be interpreted and codified within an adaptable semantic framework. The investigation seeks to view space through an alternate lens, abstracting architectural spaces into a set of numerical descriptions that can either be used to interpret the qualities of an existing space, or as a seed to generate a coherent network of spaces based on identified spatial patterns within a chosen site. The article comprises of two parts: a theoretical investigation into representing spaces through numerically expressed semantic descriptions and a case study in the form of a proposal for an underground metro station within an urban context.

summary	Gaining rigidity and strength from malleable and flexible parts is the key challenge in the emerging field of bending-active structures. The goal of this construction approach is to use the large elastic deformations of planar elements for the building of complex curved structures. Aiming to contribute to this research and to make new discoveries, the authors of this paper will look at nature for inspiration and explore how structures in the plant kingdom successfully combine high flexibility with high resilience. The focus of this study are the structural principles found in fibrous cactus skeletons. Not only do the cactus skeletons show impressive structural behavior, but also their optimized form, fiber orientation, and material distribution can inspire the further development of bending-active structures. Learning from these models, the authors will present key cactus-inspired design principles and test their practical feasibility in a prototypical installation made from millimeter-thin strips of carbon fiber reinforced polymers (CFRP). Similar to the biological role model, this 6-meter-tall lamellar structure takes advantage of clever cross-bracing strategies that significantly increase stability and improve resilience. The authors explain in more detail the underlying design and construction methods and discuss the possible impact this research may have on the further development of bending-active structures.

summary	This paper presents a 3D Concrete Printing (3DCP) experiment at the full scale of virtualarchitectural bodies developed through a computational technique based on the use of Cellular Automata (CA). The theoretical concept behind this technique is the decoding of errors in form generation and the invention of a process that would recreate the errors as a response to optimization (Adilenidou 2015). The generative design process established a family of structural and formal elements whose proliferation is guided through sets of differential grids (multi-grids) leading to the build-up of large span structures and edifices, for example, a cathedral. This tooling system is capable of producing, with specific inputs, a large number of outcomes in different scales. However, the resulting virtual surfaces could be considered as "unprintable" either due to their need of extra support or due to the presence of many cavities in the surface topology. The above characteristics could be categorized as errors, malfunctions, or undesired details in the geometry of a form that would need to be eliminated to prepare it for printing. This research project attempts to transform these "fabrication imprecisions" through new 3DCP techniques into factors of robustness of the resulting structure. The process includes the elimination of the detail / "errors" of the surface and their later reinsertion as structural folds that would strengthen the assembly. Through this process, the tangible outputs achieved fulfill design and functional requirements without compromising their structural integrity due to the manufacturing constraints.

summary	Metal joints play a relevant role in space frame constructions, being responsible for large amount of the overall material and fabrication cost. Space frames which are constructed with standardized metal joints are constrained to repetitive structures and topologies. For customized space frames, the fabrication of individual metal joints still remains a challenge. Traditional fabrication methods such as sand casting are labour intensive, while direct 3D metal printing is too expensive and slow for the large volumes needed in architecture.This research investigates the use of Binder Jetting technology to 3D print sand molds for casting bespoke metal joints in architecture. Using this approach, a large number of custom metal joints can be fabricated economically in short time. By automating the generation of the joint geometry and the corresponding mold system, an efficient digital process chain from design to fabrication is established. Several design studies for cast metal joints are presented. The approach is successfully tested on the example of a full scale space frame structure incorporating almost two hundred custom aluminum joints.
