title	The Impact of Moving through the Built Environment on Emotional and Neurophysiological State - A Systematic Literature Review
source	D. Holzer, W. Nakapan, A. Globa, I. Koh (eds.), RE: Anthropocene, Design in the Age of Humans - Proceedings of the 25th CAADRIA Conference - Volume 1, Chulalongkorn University, Bangkok, Thailand, 5-6 August 2020, pp. 641-650

summary	Despite theoretical evidence about the capabilities of visual properties of space for manipulating inhabitants' emotions, a gap in knowledge exists for empirical studies in controlled environments. Interdisciplinary studies at the intersection of architecture, psychology, and neuroscience can provide robust guidelines and criteria for designers to engineer emotions. Due to the novelty of the field, the theoretical framework for such studies is not well established. Consequently, this paper presents a systematic literature review to find and synthesize recent relevant studies at this intersection. Based on these findings, we will investigate the impact of other visuo-spatial stimuli on emotions in a rigorous way. According to the theories of emotions, manipulation of emotions is linked to oscillations in physiological responses caused by exposure to sensory stimuli. Moreover, there is a consensus that human perception is action-oriented. Therefore, our review focuses on studies that employ biosensors as subjects move in physical or virtual environments.

summary	In the early months of 2019, air pollution in Bangkok reached a record high, bringing national and international attention to the air quality in the South East Asian cosmopolitan. Although applications such as real-time pollution maps provide an environmental reading from the exterior, such information reveals the ‘here and now,’ where its record is inevitably lost through the ‘refreshing’ process of the live update and does not take increment and accumulation as factors to consider. The project was conceived around understanding the human body as precisely that medium that resists classification as either an interior or exterior environment that inherently performs as an impressionable record of its surroundings. Can a city’s toxicity be read through its living constituents? Can the living bodies that dwell, navigate, breathe, and process habitable environments be accessed? Can architecture retain a degree of independence while also performing as a beacon for the collective? Along this line of questioning, it was found that human hair can be transformed from a material that is effortlessly and continuously grown, cut, stylized, and discarded, and instead be intercepted and used in the production of public information gathering. Foll(i)cle is a collective being made of discarded human hair. Performing as a parliament for collectivity embedded with a protocol; the hairy pavilion invites the public in and presents them with a device at the center that hosts all the necessary equipment and information for anonymously and voluntarily providing hair samples for heavy metal analysis, the data of which is used in making a publically accessible toxi-cartography. Although humans are the primary subject for this study, the results suggest that extending the methodology to non-humans could prove useful in reading urban toxicity through various life forms.

title	Towards a Genome for Zero Carbon Retrofit of UK Housing
source	Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 2, Graz, 20-22 September 2023, pp. 197–206

summary	The United Kingdom has some of the worst insulated housing stock in Northern Europe. This is in part due to the age of housing in the UK, with over 90% being built before 1990 [McCrone 2017, Piddington 2020]. Moreover, 85% of current UK housing will still be in use in 2050 by which stage their Government are targeting Net Carbon Zero [Eyre 2019]. Domestic energy use accounts for around 25% of UK carbon emissions. The UK will need to retrofit 20 million dwellings in order to meet this target. If this delivery were evenly spread, it would equate to over 2,000 retrofit completions each day. Government-funded initiatives are stimulating the market, with upwards of 60,000 social housing retrofits planned for 2023, but it is clear that a system must be developed to enable the design and implementation of housing-stock improvement at a large scale.This paper charts the 20-year development of a digital approach to the design for low-carbon domestic retrofit by architects Constructive Thinking Studio Limited and thence documents the emergence of a collaborative approach to retrofit patterns on a National scale. The author has led the Research and Development stream of this practice, developing a Building Information Modelling methodology and integrated Energy Modelling techniques to optimise design for housing retrofit [Georgiadou 2019, Ben 2020], and then inform a growing palette of details and a database of validated solutions [Moorhouse 2013] that can grow and be used to predict options for future projects [D’Angelo 2022]. The data is augmented by monitoring energy and environmental performance, enabling a growing body of knowledge that can be aligned with existing big data to simulate the benefits of nationwide stock improvement. The paper outlines incremental case studies and collaborative methods pivotal in developing this work The proposed outcome of the work is a Retrofit Genome that is available at a national level.

title	Visualizing under pressure: parametric modeling of urban morphology as an agile and transparent tool for participatory planning in Brazil
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. 676-682
summary	Urban morphology in Brazilian cities is deeply related to building code parameters, such as maximum floor-to-area-ratio and building height. Planning regulations for city of Natal/RN are currently being revised, under intense industry pressure towards increasing building density in the coastal areas, despite social and environmental concerns. Prospective visualizations of multiple parametrically modeled scenarios were developed as aids in explaining the impacts of such regulation changes in a participatory planning context. Despite lacking extensive resources or data to support their development, the visualizations and the associated density information were sufficiently communicative as to be incorporated into the planning discussion.

title	Women and intersectionality: perspectives based on digital fabrication as a viable platform for assistive design
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. 267-274
summary	This article aims to present analyzes and perceptions regarding the experience of a project developed under the following axes: women, disabilities and the development of Assistive Technology in spaces called Fablabs. The study is developed according to an exploratory approach, with a qualitative nature. This paper provides an introduction, an exploration of the experiments and the reflections over the performed activities. In the practical stages, among others, methods of an ethnographic nature and Design Research were used. The group of women, mothers of children with disabilities, variable in size during the practices (from two to five people), carried out activities to develop assistive technology products using digital manufacturing tools in a public laboratory of the Fablab Livre SP Network , in the city of Sao Paulo, Brazil. The reflections of this study go towards questions related to women's self- esteem in the face of processes of inclusion in the technological area. The multi-signification of the Fablab space and the need to expand the intersectional debate within these environments are also encounters provided by this research.

title	Cultural-Smart City: Establishing New Data-informed Practices to Plan Culture in Cities

summary	The idea of the Creative City has encouraged planners to develop cultural policies to support creative economies, city branding, urban identity and urban quality. On the other side, the concept of Smart City introduced the possibility to create, collect and analyse data to inform decisions on cities. The two city agendas overlap in different ways, creating a Smart cultural city nexus, that propose similar goals and mixed methodologies, like the possibility to inform planning processes with big data-based technologies. In line with this direction, we introduced conceptual and methodological tools: the first tool is the definition of Hybrid Art Spaces, the second tool is the Singapore Art Maps (SAM), which uses social media data to locate art venues in cities (Tomarchio et al. 2016); the third tool is the Social Media Art Model, which establishes a relationship between social media production and art venues features. While these tools have already shown interesting analytics outcomes (Tomarchio et al. 2016), it is important to validate their utility among practitioners and to set protocols of practices. This paper presents results from semi-structured interviews and a focus group, as a first step towards assessing the usefulness of our three tools for cultural planning practice.

title	M-DAB - Towards re-using material resources of the city
source	Werner, L and Koering, D (eds.), Anthropologic: Architecture and Fabrication in the cognitive age - Proceedings of the 38th eCAADe Conference - Volume 1, TU Berlin, Berlin, Germany, 16-18 September 2020, pp. 127-132
doi	https://doi.org/10.52842/conf.ecaade.2020.1.127
summary	If we strive for a de-carbonized future, we need to think of buildings within a city as resources that can be re-used rather than being disposed of. Together with considerations on refurbishment options and future building materials, this gives a decision field for stakeholders which depends on the current "building stock" - the set of pre-existing buildings which are characterized e.g. by building period, location and material composition. Changes in that context are hard to argue for since (1.) some depend on statistics, other (2.) on the concrete neighborhood and thus the space in which buildings are embedded, yet again others on (3.) future extrapolations again dealing with both of the aforementioned environments. To date, there exists no tool that can handle this back-and-forth between different abstraction levels and horizons in time; nor is it possible to pursue such an endeavor without a proper framework. Which is why the authors of this paper are aiming to provide one, giving a model of change in the context of re-using material resource of the city, when faced with numerous abstraction levels (spatial or abstract; past, current or future) which have feedback loops between them. The paper focuses on a concrete case study in the city of Vienna, however, chances are high that this will apply to every other building stock throughout the world if enough data is available. As a matter of fact, this approach will ensure that argumentation can happen on multiple levels (spatial, statistical, past, now and future) but keeps its focus on making the building stock of a city a resource for sustainable development.

title	Computational Generation of Hybrid Façades for a Focal Context - The case of Naser-Khosrow Street in Tehran
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 2, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 333-340
doi	https://doi.org/10.52842/conf.ecaade.2021.2.333
summary	The purpose of this paper is to use shape grammar methodology to generate contextualized urban façades within the focal context of Naser-Khosrow Street in Iran's capital city of Tehran. The history of Naser-Khosrow Street, which is considered a significant historic urban space, begins in the Safavid period (1735-1501). Yet, the urban history and historical significance of this street have been neglected in recent years. Evidence of a sense of turmoil and incompatibility between the modern and traditional architectural façades featured on the street is easily observed. Against this background, this paper offers façade models generated based on the computational methodology developed by Hadighi and Duarte (2019, 2020) to determine and capture the hybrid expression of European modernist and American traditional styles. In this spirit, the systematic methodology of shape grammar is expanded to the focal urban area of Naser-Khosrow Street to generate new façade layouts referencing the characteristic features of some of the iconic buildings located there.

title	Spatial analysis to create a walkability index. Case study: San Juan Street, Medellín
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. 433-440
summary	To walk represents one of the main ways of commuting, either by necessity or pleasure, it is a guaranteed way for everyone and it contributes significantly to the health and well-being of people. However, Medellín´s urban space design is not planned to improve walking conditions. In this context, a spatial index was built based on the components that influence the urban scene, which allows to evaluate the walking experience, not only its possibility, on an axis of the city. It concludes how these variables prioritize other actions and strategies that must be taken into consideration to build a walkable city.

title	Negotiating human engagement and the fixity of computational design: Toward a performative design space for the differently-abled bodymind
source	International Journal of Architectural Computing vol. 18 - no. 2, 174-193
summary	Computational design affords agency: the ability to orchestrate the material, spatial, and technical architectural system. In this specific case, it occurs through enhanced, authored means to facilitate making and performance—typically driven by concerns of structural optimization, material use, and responsivity to environmental factors—of an atmospheric rather than social nature. At issue is the positioning of this particular manner of agency solely with the architect auteur. This abruptly halts—at the moment in which fabrication commences—the ability to amend, redefine, or newly introduce fundamentally transformational constituents and their interrelationships and, most importantly, to explore the possibility for extraordinary outcomes. When the architecture becomes a functional, social, and cultural entity, in the hands of the idealized abled-bodied user, agency—especially for one of an otherly body or mind—is long gone. Even an empathetic auteur may not be able to access the motivations of the differently-abled body and neuro- divergent mind, effectively locking the constraints of the design process, which creates an exclusionary system to those beyond the purview of said auteur. It can therefore be deduced that the mechanisms or authors of a conventional computational design process cannot eradicate the exclusionary reality of an architectural system. Agency is critical, yet a more expansive terminology for agent and agency is needed. The burden to conceive of capacities that will always be highly temporal, social, unpredictable, and purposefully unknown must be shifted far from the scope of the traditional directors of the architectural system. Agency, and who it is conferred upon, must function in a manner that dissolves the distinctions between the design, the action of designing, the author of design, and those subjected to it.

title	Saltatur

Online and Global. 24-30 October 2020. edited by M. Yablonina, A. Marcus, S. Doyle, M. del Campo, V. Ago, B. Slocum. 108-113.
summary	The Saltatur (Dancer in Latin) demonstrates innovative research in the design and fabrication of a prefab structure consisting of spatial concrete nodes assembled in a compression-only configuration. The compression-only body is kept in equilibrium using the post-tensioning steel rods at the top and the bottom of the structure, supporting an ultra-thin glass structure on its top. A node-based assembly was considered as a method of construction. An innovative detailing was developed that allows locking each member in its exact location in the body, obviating the need for a particular assembly sequence. A bespoke steel connection transfers the tensile forces between the concrete members effectively. Achieving a high level of efficiency in utilizing concrete for spatial systems requires a robust and powerful structural design and fabrication approach that has been meticulously exhibited in this project. The structural form of the project was developed using a three-dimensional geometry-based structural design method known as 3D Graphic Statics with precise control over the magnitude of the lateral forces in the system. The entire concrete body of the structure is held in compression by the tension ties at the top and bottom of the structure with no horizontal reactions at the supports. This particular internal distribution of forces in the form of the compression-only body reduces the bending moment in the system and, therefore, the required mass to span such a distance.

doi	https://doi.org/10.52842/conf.ecaade.2020.2.089
summary	Waning of vigorous discourses about the idea of space as essence in architectural design concurred with the emergence of digital architecture. The notion of space was replaced with the underlying notion of form facilitating optimization of performances and form-generation in digital design ever since. Within the context of digital architecture, the current research investigates a formal method to reintroduce spatial aspects, based on dynamics of architectural space in relation to form, into digital design processes. Accordingly, a computational framework is devised employing the idea of space as dynamic field conditions, in order to capture dynamic interrelation of architectural space with architectural form. That is, spatial dynamics are regarded as data embedded in architectural space, that can imply operational aspects of spatial experiences and / or stimulate corporeal engagements with experiential space, as concepts as action potentials and affordances do (Rasmussen 1964). As a result, the research aims to contribute to the body of knowledge that endeavour to systematize architectural sensibilities that are implicit in design processes by externalization utilizing computation.

title	Sanitary Sanity: Evaluating Privacy Preserving Machine Learning Methods for Post-occupancy Evaluation

doi	https://doi.org/10.52842/conf.caadria.2020.2.697
summary	Traditional post-occupancy evaluation (POE) of building performance has typically privileged physical building attributes over human behavioural data. This is due to a lack of capability and is especially the case for private spaces such as Sanitary Facilities (SFs). A privacy-preserving sensor-based system using Machine Learning (ML) was previously developed, however it was limited to basic body position classification. Yet, SF usage behaviour can be significantly more complex. This research accordingly builds on the aforementioned work to expand behavioural classifications using a sensor-based ML system. Specifically, the case study uses a GridEYE thermal sensor array, which is trained on a cubicle location within a workplace SF. A variety of ML algorithms are then evaluated on their behaviour-classifying ability. A detailed analysis of behaviour-classification performance is then provided. A system with greater fidelity is thus demonstrated, albeit hampered by imprecise behaviour definitions. Regardless, this contributes to the capability of the broader field of research that is investigating Evidence Based Design (EBD) by extending the ability to examine human behaviour, especially in private spaces. This further contributes to the growing body of work surrounding SF provision.

title	From HCI to HVRI - How different will the interaction of digital architecture design be?
source	D. Holzer, W. Nakapan, A. Globa, I. Koh (eds.), RE: Anthropocene, Design in the Age of Humans - Proceedings of the 25th CAADRIA Conference - Volume 2, Chulalongkorn University, Bangkok, Thailand, 5-6 August 2020, pp. 253-262
doi	https://doi.org/10.52842/conf.caadria.2020.2.253
summary	This paper contributes to the conference theme by looking at the human impact factors in the context of virtual reality interaction. The creation of architectural design drawings was done through pens and rulers in the beginning. Although the process is time-consuming, the connection of the mind and body is very close and every line drawn are done through the motion of the human body. The development of computer speed up the design process but the generation of the drawings are done with the keyboard and mouse. This human-computer interaction (HCI) disrupted the body-mind connection since the controls are now pointing, dragging and clicking. Architects were having a hard time accustoming to the new methods but gave up to the speed of its efficiency. However, architects never lose their skills to draw and sketch when brainstorming design. The coming of virtual reality (VR) provides an opportunity to bring back this connection. This paper explores the possibilities of human-virtual reality interaction (HVRI) through analysing the currently available VR tools and understand how close they are to this mind-body connection.

title	Sewing Pneumatic Textures - three-dimensional digital design based on the craft of dressmaking
source	D. Holzer, W. Nakapan, A. Globa, I. Koh (eds.), RE: Anthropocene, Design in the Age of Humans - Proceedings of the 25th CAADRIA Conference - Volume 1, Chulalongkorn University, Bangkok, Thailand, 5-6 August 2020, pp. 115-124
doi	https://doi.org/10.52842/conf.caadria.2020.1.115
summary	This project explores a novel approach to digitally designing pneumatic membrane structures, utilizing traditional sewing methods from dressmaking. These sewn fabric manipulation techniques are commonly used to fit flat non-stretchy fabrics around the curvature of the body. The goal is to adapt these methods to create, shape, texture, and articulation on the pneumatic surfaces. This is in contrast with other research that is interested in creating smooth minimal surfaces with complex paneling patterns. The expression of textures explore engagement with tactility, addressing desires of playful touch and comfort within the built environment. Computer software for the fashion industry is used in the design process. The software has built in simulations and works with CAD-CAM software to produce patterns, which streamlines production and fabrication. The prototypes produced test the possibilities of these methods of sewing and the physical outputs for shape, tactility, and aesthetics.

title	Irradiated Shade

summary	The paper details computational mapping and modeling techniques from an ongoing design research project titled Irradiated Shade, which endeavors to develop and calibrate a computational toolset to uncover, represent, and design for the unseen dangers of ultraviolet radiation, a growing yet underexplored threat to cities, buildings, and the bodies that inhabit them. While increased shade in public spaces has been advocated as a strategy for “mitigation [of] climate change” (Kapelos and Patterson 2014), it is not a panacea to the threat. Even in apparent shade, the body is still exposed to harmful, ambient, or “scattered” UVB radiation. The study region is a binational metroplex, a territory in which significant atmospheric pollution and the effects of climate change (reduced cloud cover and more “still days” of stagnant air) amplify the “scatter” of ultraviolet wavelengths and UV exposure within shade, which exacerbates urban conditions of shade as an “index of inequality” (Bloch 2019) and threatens public health. Exposure to indirect radiation correlates to the amount of sky visible from the position of an observer (Gies and Mackay 2004). The overall size of a shade structure, as well as the design of openings along its sides, can greatly impact the UV protection factor (UPF) (Turnbull and Parisi 2005). Shade, therefore, is more complex than ubiquitous urban and architectural “sun” and “shadow studies” are capable of representing, as such analyses flatten the three-dimensional nature of radiation exposure and are “blind” to the ultraviolet spectrum. “Safe shade” is contingent on the nuances of the surrounding built environment, and designers must be empowered to observe and respond to a wider context than current representational tools allow.

The method is inspired by the observation that beads forced together along a string will become constrained until they spontaneously rigidify. This behavior is easily observed using any household string and flat-faced beads and recalls the mechanism behind classic crafts such as push puppets. However, specific examples of architectural applications are lacking. We analyze how this phenomenon occurs through static force analyses, physical tests, and simulation, using a rigid body physics engine to validate digital prototypes. We develop a method of designing custom bead geometries able to be produced via generic 3D-printing technology, as well as a computational path-planning toolkit for designing ways of threading beads together. We demonstrate how these custom bead geometries and threading paths influence the acquired structure and its assembly. Finally, we propose a means of scaling up this phenomenon, suggesting potential applications in deployable architecture, mortarless assembly of nonfunicular masonry, and responsive architectural systems.

summary	From architecture to art, and back to architecture: this research interrogates the potential of computation to bridge between both disciplines. The endeavour is twofold, a body of drawings is produced through algorithms that translate cultural and natural events into thousands of lines. Further on, these drawings are used to delineate a procedure in order to give rise to experimental buildings. By means of applying organizational principles outlined in the notion of fields, and the use of non-deterministic algorithms, a method to generate architecture from the realm of the visual arts is explored.

summary	This work-in-progress paper describes a body of research that utilizes the invention and application of a novel method to 3D-print calcium carbonate (CaCO3). The resultant 3D-printed objects can be computationally optimized and used as a scaffold for the growth of various aquatic life that exists at the interface of soft edges and the built, specifically (but not limited to) coral polyps. Rather than utilizing materials designed for anthropocentric terrestrial environments, we can harness materials and forms native to aquatic ecosystems in combination with advanced computation and fabrication techniques to help foster applied research in service to healthier ecosystems and cohabitation. This paper introduces the novel application of a 3D-printed calcium carbonate, mimicking a similar material composition to that of coral, and describes the additive manufactured medium with regard to 3D powder-printing methodologies. Hypothesis and proposal of morphogenesis in surface and volume are identified as key factors for interface with aquatic organisms. Current and future applications are additionally exhibited through a combination of material composition, surface, and form as targeted intervention and artificial restoration for aquatic ecosystems. While our planet requires anthropocentric mitigation strategies for reduction of greenhouse gases that contribute to aquatic life’s greatest threats, we must simultaneously develop strategies for adaptation that immediately respond to the current realities of a changing climate.

title	3D Printed Responsive Wood Interfaces: Shape-Changing Origami-Inspired Prototypes
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. 600-607
summary	In this paper, we present a study for a 3D printed responsive wood interface in which we employed a scientific approach to assess the effects of various 3D printing parameters on shape-change. A full factorial design of experiments is conducted to determine the variables that maximize hygromorphic response. Analyzing the results of the experiments, we designed and fabricated origami-inspired prototypes, and tested their bimorph and gradient actuation. The contribution of this study to the growing body of literature on 3D printing responsive wood- based composites is the integration of gradient actuation and origami-inspired shape-changing strategies.
