title	Human-Computer Interaction for Urban Rules Optimization
source	Abdelmohsen, S, El-Khouly, T, Mallasi, Z and Bennadji, A (eds.), Architecture in the Age of Disruptive Technologies: Transformations and Challenges [9th ASCAAD Conference Proceedings ISBN 978-1-907349-20-1] Cairo (Egypt) [Virtual Conference] 2-4 March 2021, pp. 603-613
summary	Faced with the complexity of manual and intuitive management of urban rules in architectural and urban design, this paper offers a collaborative and digital human-computer approach. It aims to have an Authorized Bounding Volume (ABV) which uses the best target values of urban rules. It is a distributed constraint optimization problem. The ABV Generative Model uses multi-agent systems. It offers an intelligent system of urban morphology able to transform the urban rules, on a given plot, into a morphological delimitation permitted by the planning regulations of a city. The overall functioning of this system is based on two approaches: construction and supervision. The first is conducted entirely by the machine and the second requires the intervention of the designer to collaborate with the machine. The morphological translation of urban rules is sometimes contradictory and may require additional external relevance to urban rules. Designer arbitration assists the artificial intelligence in accomplishing this task and solving the problem. The Human-Computer collaboration is achieved at the appropriate time and relies on the degree of constraint satisfaction with fitness function. The resolution of the distributed constraint optimization problem is not limited to an automatic generation of urban rules, but involves also the production of multiple optimal-ABV conditioned both by urban constraints as well as relevance, chosen by the designer.

title	From Design to the Fabrication of Shellular Funicular Structures
doi	https://doi.org/10.52842/conf.acadia.2021.328
source	ACADIA 2021: Realignments: Toward Critical Computation [Proceedings of the 41st Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 979-8-986-08056-7]. Online and Global. 3-6 November 2021. edited by B. Bogosian, K. Dörfler, B. Farahi, J. Garcia del Castillo y López, J. Grant, V. Noel, S. Parascho, and J. Scott. 328-339.
summary	Shellular Funicular Structures (SFSs) are single-layer, two-manifold structures with anticlastic curvature, designed in the context of graphic statics. They are considered as efficient structures applicable to many functions on different scales. Due to their complex geometry, design and fabrication of SFSs are quite challenging, limiting their application in large scales. Furthermore, designing these structures for a predefined boundary condition, control, and manipulation of their geometry are not easy tasks. Moreover, fabricating these geometries is mostly possible using additive manufacturing techniques, requiring a lot of supports in the printing process. Cellular funicular structures (CFSs) as strut-based spatial structures can be easily designed and manipulated in the context of graphic statics. This paper introduces a computational algorithm for translating a Cellular Funicular Structure (CFS) to a Shellular Funicular Structure (SFS). Furthermore, it explains a fabrication method to build the structure out of a flat sheet of material using the origami/ kirigami technique as an ideal choice because of its accessibility, processibility, low cost, and applicability to large scales. The paper concludes by displaying a structure that is designed and fabricated using this technique.

title	Algae, Gobiidae Fish and Insects that inspire Coastal Custodian Entities - Digital models for a real-virtual space using TouchDesigner
doi	https://doi.org/10.52842/conf.ecaade.2022.1.361

summary	At the beginning of the twenty-first century, a discipline at the intersection of digital art and science explores how natural and artificial species are affected, coexist, and feed back to humans based on multi-scalar hybrid models. They embody types of surveillance entities or non-human custodians, and serve as inspiration for another generation of designs produced ten years later, the case studies that are presented here. This paper explains the design and parametric fundamentals of a digital architecture installation at the University of Alicante (Spain 2021) using CNC models and the TouchDesigner programming environment. The installation contains a clan of technological-virtual hybrid species, non-human custodians, which: (a) strengthen the Proposal’s discourse on the recognition of legal identity of the Mar Menor lagoon (Southeast Spain); (b) incorporate reactive designs; (c) help raise awareness of the effect of human actions on the lagoon’s ecology and nearby streams. The viewpoint is not anthropocentric, because it adopts the perspective of the foraging fish species or the oxygen-seeking algae species, among others, in order to reveal the deterioration processes. In most cases, the result is a sort of synaesthetic conversation that interweaves light, sound, movement and data.

title	Interactive Virtual Sand Table: An Improved Alternative Participatory Design Tool for Architectural Design
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 67–78
summary	With the planning reform in China, public participation is becoming increasingly crucial to the success of rural planning. However, it is difficult to involve various stakeholders in planning and design projects, mainly due to insufficient planning knowledge and computer skills. Therefore, this paper introduces the Interactive Virtual Sand Table (IVST) as a participatory design tool so that non-professional users can use it conveniently and promote interactive and efficient collaborative design discussion. The IVST based participatory tool was applied in Xidong Village, Chaozhou City, Guangdong Province, China. The results show that IVST interaction is more natural and reduces non-professional users' difficulty participating in the design. Participants' ability to participate was highly enhanced, and their interest in IVST visualization was highly activated. In conclusion, the Interactive Virtual Sand Table highly supports the participatory village planning process and may apply to other areas and domains.

title	SOM’s Computer Group: Narratives of women in early architectural computing
source	International Journal of Architectural Computing 2021, Vol. 19 - no. 3, 213–225
summary	Cultural narratives of digital technology in architecture rely heavily upon stories of unique, almost always male, genius and often deny the collective intellectual labor of technology’s construction. These narratives are perpetuated by a historical record which does not fully address the contributions of women to the history of digital technology. Because this history is not well-documented, there is an opportunity to represent these events in a manner which is more inclusive and equitable. Toward that end, this article focuses on narratives from the SOM Computing Group (1964–1990), as a means of correcting the historical record and addressing gender equity in the profession. The interviews collected here highlight several women who helped to integrate technologies into architecture through professional experimentation and cross-disciplinary collaboration. While it is not a comprehensive history, this work represents the beginning of an agenda to produce a history of technology in architecture which better reflects the contributions of women to the digital designs of today.

summary	While technology has rapidly become available to more people, there is still a lack of representation and diversity among the individuals who develop and create with it. The implication of computational design and digital fabrication scholarship is that knowledge circulates through publications when, in a practical sense, it tends to be consolidated within a limited set of people and institutions. Even as the costs of hardware trend lower and free software and workfl ows are published online, specialized education and social capital are often necessary to apply this knowledge and produce innovative digital designs. And so, access to technology alone does not necessarily lead to greater equity. Improving access to digital design knowledge—specifically methods and processes—could help address this concern. In scientific publications outside of architecture, the methodology section and technical appendices are critical to verification and advancement of the field. If an experiment cannot be duplicated, the validity of the result is called into question. The same standard does not seem to apply in computational design and digital fabrication, as the descriptions of projects are seldom detailed, transparent, or instructive enough to permit replication.

title	COVID-19 and the City: An Analysis of the Correlation between Urban and Social Factors and COVID-19 in Fortaleza, Brazil
source	De Luca, F, Lykouras, I and Wurzer, G (eds.), Proceedings of the 9th eCAADe Regional International Symposium, TalTech, 15 - 16 June 2023, pp. 45–52
summary	The COVID-19 pandemic has been the biggest sanitary crisis humanity has ever faced, the virus has contaminated 662.717.929 people worldwide and killed 6.701.270 people. However, these numbers were not distributed equally at international, national or urban scale. In Fortaleza, Brazil, city studied in this paper, data from 2021 and 2022 epidemiologic reports suggest a contamination pattern that starts in neighborhoods with higher Human Development Index (HDI) and then goes to lower HDI neighborhoods, however, throughout all of this cycle, low HDI neighborhoods tend to have a higher lethality rate. These facts raised the hypothesis that those neighborhoods have specific urban and social factors that affect the capacity to respond and prevent COVID-19. The main objective of this paper is to identify the correlation of some urban and social factors with COVID-19 data. To achieve that, the authors selected seven variables (access to water rate, literacy rate, waste collection rate, population density, access to electric energy rate, sanitation rate and average monthly income) to correlate with four COVID- 19 indicators (total number of cases, total number of deaths, contamination rate and lethality rate). For this, it was chosen to apply Spearman’s correlation coefficient and for the calculation the statistical software Jamovi was used. The results show that the literacy rate, the access to electric energy rate and average monthly income have a positive correlation with the contamination rate, however these same variables have a negative correlation with the lethality rate.

title	Designing Crowd Safety - Agent-Based Pedestrian Simulations in the Early,Collaborative Design Stages
doi	https://doi.org/10.52842/conf.caadria.2021.2.729

summary	Contemporary agent-based pedestrian simulations offer great potential to evaluate architectural and urban design proposals in terms of medical risks, crowd safety, and visitor comfort. Nevertheless, due to their relative computational heaviness and complicated input-parameters, pedestrian simulations are not employed during the design process commonly. Simulation results significantly impact planning decisions, especially when they are already available in the early design phases. This paper analyzes the requirements of pedestrian simulations for early planning stages, such as seamless integration into iterative and collaborative design processes, interactivity, and appropriate visualization of results. For this purpose, we combine two existing projects: a high-accuracy pedestrian simulation and the CDP//Collaborative Design Platform. To adapt the simulation method to the requirements of early planning stages, we investigate interactions that blend intuitively with the design process and enable multiple users to interact simultaneously. We simplify simulations input parameters to match the level of detail of the early design phases. The simulation model is adapted to facilitate continuous and spontaneous interactions. Furthermore, we develop visualization techniques to support initial design negotiations and present strategies for compensating computation time and giving constant feedback to a dynamic design process.

summary	The COVID-19 pandemic has made most schools, universities, and gathering spaces fully virtual. Commonly used communication platforms such as Zoom, Skype, and Microsoft Teams are limited in recreating physical interactions and offer mostly static interfaces with limited occasions for spontaneous encounters. This project creates a space that seeks to address this issue, first through the digitization of familiar physical spaces, and then through their augmentation via WebXR technologies[1]. A gamification strategy is adopted, where users can virtually learn, collaborate and socialize through personalized avatars within a dynamic and multi-sensorial digital environment. In this paper, we present a completed prototype that is currently being tested at the Harvard Graduate School of Design. The school of architecture has been digitized and experientially augmented thanks to an asymmetrical system that offers rich modalities of interaction through different platforms. The project builds upon the wide experiential potential of digital platforms, otherwise not possible in reality, and implements a customized multi-modal user interface (Reeves et al. 2004).

title	A Generative Approach to Social Ecologies in Project [Symbios]City
doi	https://doi.org/https://doi.org/10.1007/978-981-16-5983-6_2
source	Proceedings of the 2021 DigitalFUTURES The 3rd International Conference on Computational Design and Robotic Fabrication (CDRF 2021)
summary	The following paper talks about the studio project [Symbios]City, which is developed as a design research project in 2020–2021 Schumacher’ studio on social ecology of the graduate program in Architectural Association’s design research lab. The project aims to create an assemblage of social ecologies through a rich but cohesive multi-authored urban district. The primary ambition is to generate an urban area with a characterful, varied identity, that achieves a balanced order between unity and difference avoiding both the sterile and disorienting monotony of centrally planned modernist cities and the (equally disorienting) visual chaos of an agglomeration of utterly unrelated interventions as we find now frequently. Through a thorough research process, our project evolves mainly out of three principles that are taken into consideration for the development of our project: topological optimization, phenomenology, and ecology. By “ecology”, we understand it as a living network of information exchange. Therefore, every strategy we employ is not merely about reacting to the weather conditions, but instead it is an inquiry into the various ways we can exploit the latter, a translation of the weather conditions into spatial and programmatic properties. [Symbios]City therefore aims at developing a multi-authored urban area with a rich identity that achieves a balance between the various elements. [Symbios]City began formally from topological optimization, developed based on studies on ecology, and concluded the design following our phenomenological explorations, aiming at a complex design project that unifies the perception of all scales of design: from the platform to the skyscrapers.

title	Short Stack

Online and Global. 24-30 October 2020. edited by M. Yablonina, A. Marcus, S. Doyle, M. del Campo, V. Ago, B. Slocum. 120-123
summary	Short Stack is a bare minimal structure using only laminated sheets of structural metal decking for all elements of its structure and enclosure. The project operates under a simple principle. Structural metal decking is a one-way system that resists loads well in one direction, but not in the other. When this decking is stacked into rotated sections and tensioned together, the resultant sandwich of corrugated metal is resistant to loading in every direction. These sandwiches become walls, floors, and roofs to a temporary structure. The compounded effect at the edges of the rotated and cropped decking is one of filigree or an ornamental articulation. The sandwich, which is mostly hollow due to the section of the decking, provides a sense of airy lightness that is at odds with its bulky mass. The structure, therefore, teeters between being unexpectedly open and at once heavy. The economy of the project is in its uniformity and persistent singularity. By maintaining a single palette of material and using a plasma cutting CNC bed to cut each section of the decking, the structure is simply assembled. The digital intelligence that lies underneath the apparent formal simplicity of the project is two-fold. Firstly, each sheet of metal decking is different from the next. Because of the locations of bolt-holes and constant variability of rotation and cropping of each sheet, it is a project that expresses uniformity rather than articulation through discretization. Secondly, the project appears solid and monolithic but is hollowed structurally to minimize the weight of the assembly. Parametric tools are implemented to maximize material efficiencies by hollowing the interior of each sandwich for load optimization. The project is presently in prototyping and documentation and will go into construction in Spring 2021 on a site in downtown Denver.

title	Exploiting game development environments for responsive urban design by non-programmers - melding real-time ABM pedestrian simulation and form modelling in Unity 3D

summary	Precinct-level pedestrian simulation often requires moderate to high-level modelling skills with a steep learning curve, and is usually non-flexible, time-consuming and exclusive of the broader public community. Confronting these problems, our research investigates a novel and agile workflow to test precinct pedestrian behaviours by melding agent-based simulation (ABM) and responsive real-time form modelling mechanisms within accessible visualisation of city and precinct environments in a game engine, Unity 3D. We designed an agent system prototype of configurable and interoperable nodes that may be placed in an urban modelling scenario. Realtime CSG, a fast polygon-based modelling plugin, is also introduced to our workflow where users can use the evidence observed when running a scenario to quickly adjust the street morphology and buildings in response. In this process, end users are kept in the design loop and may make critical adjustments, whereby a responsive, collective, informed design agenda for our built environments can inform more detailed outcomes of pedestrian behaviour and action and promote more efficient collaborations for both professionals and local communities.

summary	Academic papers are full of final drawings and diagrams but gloss over process work, “less glamorous” images, and the amount of time and labor behind a fi nal product. Certain skills and expertise cannot be taught but are instead collected from years of personal experience – a body of knowledge inaccessible to some unless passed on through e-mails, Zoom calls, or personal observations. When dealing with these seemingly esoteric topics, it becomes easy to feel isolated in the problems, failures, or questions that arise and cannot be easily accessed in academic journals or a simple Google search. Although exacerbated by the global pandemic’s mandates and shifts in the way work is done - this feeling is not new. The following pages record clay 3D printing research on a KUKA industrial robotic arm completed by two 5th year undergraduate architecture students. Through drawings, images, and text, this field note documents decisions, failures, messes, and successes compiled from a year of socially distanced learning, researching, and living.

summary	Autonomously shape-changing granular materials are investigated as architectural construction materials. They allow the embedding of different mechanical behaviors in the same material system through the design of their component particles. Granular materials are defined as large numbers of individual elements of larger than a micron. Because they are not bound to each other, only the contact forces act between them. The design of individual particles affects the behavior of a granular substance composed of such materials. The design process involves the definition of the form and materiality of the particle in relation to the desired function of the granular material. If shape-change materials are deployed in the making of the particles, the granular material can have more than one designed behavior, for example, both liquid and solid phases. Autonomously shape-changing granular materials have seldom been explored in either architecture or granular physics. Thus their exploration is both a relevant and a novel contribution to the field of granular architectures in specific and computational architectural design in general. This article outlines the field of autonomously shape-changing granular materials and embeds them in the current state. Experimental and simulation methods for the development of shape-changing particles and granular materials are introduced. A case study on the development and testing of autonomously shape-changing particles made from a bimetal is also presented. Further research is outlined with respect to the practical, methodological, and conceptual development of an autonomously shape-changing designed granular material.

summary	Our research team develops sustainable and inclusive typologies of micro-architecture. These micro-architectures, aided by cutting-edge technologies, give room to more inclusiveness and functional-ductility. We are convinced that nothing is static, there is not just a single possible future. Because of that, we generate real/virtual architectures that do not respond only to a single type of user, place or use. In this case, we introduce a typological model focused on health and wellness services, currently under development by parametric design. Located in the city of Córdoba, Argentina and placed near public parks (where many citizens practice sports and recreational outdoor activities)). We use energy-efficient local technology to power devices that adapt to local weather; moreover, the equipment provides performance data via audio, visual and tactile outputs, and in adjustable-position devices.

title	Task and Motion Planning for Robotic Assembly

summary	When programming robotic assembly processes, it is often necessary to create a sequential list of actions. Some actions are robotic motions (requiring motion trajectory), and some are for controlling external equipment, such as grippers and fastening tools. The act of planning these actions and motion trajectories is called Task Planning and Motion Planning. Existing literature in robotics explored many different planning algorithms for planning a single trajectory to planning a complete sequence of tasks where continuity is maintained [Garrett et al, 2021]. Many application literature focused on the TAMP for service robots, medical robots, and self-driving cars, while there are few examples for architectural applications. For digital fabrication and automated construction, the planning method has to be adapted to the needs of architectural assemblies and the scale of construction [Leung et al, 2021]. Some of the unique challenges are the highly bespoke workpiece and assembly geometry, the large workpiece (e.g., long beams), and a dense collision environment. This three-day hybrid workshop addressed the needs of the architectural robotics community to use industrial robotic arms to assemble highly bespoke objects. The objects do not have any repetitive parts or assembly targets. The workshop leaders shared their experiences using industrial robots to construct large-scale timber structures. One of the most useful techniques is the recently published “Flowchart Planning Method,” where task sequence is planned using a flowchart, and motion trajectories are planned in a second pass [Huang et al, 2021].

It uses the database of over 45,000 public trees in the city’s Open Data Portal (City of Palo Alto, n.d.) as the basis for a collective, three-dimensional map of one aspect of the city’s ecology. The installation performs like a compass, with each rib corresponding directionally to a respective “pie slice” of territory raiding outwards from City Hall. The trees are represented by bumps on the outer edge of each rib, so the zones with more trees result in ribs with more relief. The ribs are arranged in a circle, gradually changing in height, profile, and color to create a dynamic form that is different from each side

summary	Prevention and management of epidemic is a protracted war. As large community in city, universities are key regions in the anti-epidemic period. However, the current epidemic prevention and management measures in many universities do not compatible with the spatial form and the characteristics of the population, likely to lead to waste of resources and cause conflicts. The research simulates campus environment by constructing GIS model, and simulates the behavior of campus crowd by ABM. Under the coupling effect of the two, the real-time calculation of the spread of epidemic in universities can be calculated in real-time, making up for the deficiency of GIS model which can only do static data analysis. On this basis, research takes South China University of Technology as an example and assumes three epidemic prevention management measures, i.e. closed-off management, zoning management and self prevention, respectively to simulate the spread of the epidemic, sum up the results of different management measures and provide certain suggestions.

summary	This paper discusses the potential derived by developing a sketching interface to achieve an intuition-oriented design process for beginners, focusing on fabrication. Using experiments and a questionnaire, we evaluate both the method developed and the change in the consciousness of participation in full-scale 3D (Three Dimensional) design. A specific feature of the developed sketching interface is that it is not fully packaged; it means designers can modify and customize a tool to their needs. However, there was no difference between the sketching interface and ordinary 3D CAD (Computer-Aided Design) in increasing the motivation to use computers to fabricate; including a customizable feature (not fully packaged) could open up the possibilities of increasing motivation for the subjects to participate in the fabrication. The experiment results demonstrated that the sketching interface input system has equivalent reproducibility to existing 3D CAD, and even beginners can intuitively and immediately realize fabrication.

title	Daylighting and the Elderly: A Study of Daylight Accessibility and Envelope Retrofit in Southern Chile's Senior Home
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 1333–1344
summary	In the next 25 years, the elderly population will increase on average to 65 thousand people annually in Chile (INE, 2018). Their independent living is jeopardized partially for diminished visual capacity that difficult spatial perception. Although light does not correct vision impairment, adequate light levels can respond to the needs of older people as preventing visual errors. This study evaluates daylighting availability in an assisting living residence in a southern city in Chile. A quantitative approach resulted in the identification of envelope-retrofit strategies that allow achieving recommended levels of natural lighting, particularly in shared spaces where residents spend most of the day. The results show that it would be possible to achieve better light availability, as it also allows for a better understanding of the contributions of the building envelope. Finally, the study outlines recommendations for future retrofits that meet requirements for visual comfort for a growing senior population.
