title	Policy considerations for Extended Reality (XR) implementation in Urban Planning and the Built Environment
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. 713–722

summary	In this paper, we discuss innovation policy for the implementation of extended reality (XR) to the urban planning sector and within the built environment. XR allows human users to evaluate urban planning proposals from first-person, embodied vantage points at realistic scale, offering utility for solving problems in the urban planning and design sector, particularly in user participation, user feedback and communication. However, we find that a clear model for the integration of XR technology to urban planning is lacking, with best practices and funding mechanisms still yet to be identified, creating barriers hindering adoption. We present an analysis of the innovation system and economic incentives for XR development, pointing to challenges for wide scale adoption in XR, including the creation of compelling content and the necessity for regulatory oversight. We discuss innovation structures in urban planning, pointing to an unclear strategy for innovation and the lack of research incentives within these institutions. We propose that public-private partnerships including cross-disciplinary development opportunities across sectors will need to be developed to better apply XR to urban planning, while discussing some of the advantages to be found for XR developers in creating content within urban environments. We further suggest that integration between XR and the regulatory and procedural rules of zoning may be necessary to ensure that XR technology is beneficial to society while also allowing XR developers exposure to a broad consumer base. In conclusion, we present policy proposals for collaboration between private technology companies and public planning organizations, with a focus on ensuring that XR technology is developed and applied in a way that is aligned with the priorities and objectives of the public while still creating value for investors and innovators.

summary	Although simulation models have been recently employed to model and examine pedestrian behavior in urban areas, comparable research has not been pursued in campus environments despite their importance as a critical area of inquiry. Those models' paucity and methodological limitations suggest investigating new research and design strategies to objectively assess and describe how the qualities of campus spaces and zones influence human behavior and, hence, predict the patterns of users' interaction and space usage. Those patterns and their impact on health have been pointed out as critical to the relationship among public space and quality of life due to Covid-19. There is an urgent need to develop decision support tools that would support interactive design processes and enhance the quality of open space design in terms of sense of space, place-making, and user interaction. To that goal, this study has proposed the integrated parametric BIM-based campus life simulation "CampuSIM" as a method for parametrization of the qualities of pedestrian campus zones and spaces. The study proposed the use of multi-objective optimization methods to fulfill various campus quantifiable and non-quantifiable design objectives. The significance of the proposed tool will result from its potential application in a wide range of complex, dynamic pedestrian behavior scenarios such as flows, social simulations, and design.

title	Customising Urban Joy: Urban Planning Mechanisms for the Mass - Customisation of Cities, through the Quantifiable Nature of Joy Using Geo-tagged Social Media Data
source	García Amen, F, Goni Fitipaldo, A L and Armagno Gentile, Á (eds.), Accelerated Landscapes - Proceedings of the XXVII International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2023), Punta del Este, Maldonado, Uruguay, 29 November - 1 December 2023, pp. 31–42
summary	The paper examines citizen participation in a digitally-driven society and the disparity between desired and existing cities. It emphasises the need to transform cities into adaptable environments that respond to the needs of residents. Traditional top-down urban planning often fails to match the flexible nature of digitised urban residents. To address this, an agent-based model is employed, evaluating urban environments based on individual sentiment derived from social media API. The study case of Wittenberge, Germany, showcases the methodology, including the creation of a 3D digital twin using open data sources and generating agents with unique personalities from social media keywords. These agents' "life satisfaction score" reflects their ability to fulfil daily needs and preferences within a 20-minute walking radius.

title	Predicting Network Integration Based on Satellite Imagery Around High-Density Public Housing Estates Through Machine Learning
source	García Amen, F, Goni Fitipaldo, A L and Armagno Gentile, Á (eds.), Accelerated Landscapes - Proceedings of the XXVII International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2023), Punta del Este, Maldonado, Uruguay, 29 November - 1 December 2023, pp. 795–806
summary	In studies focusing on environmental and health aspects of urban planning, the integration of road networks within the built environment emerges as an important metric for assessing the livability and healthiness of neighborhoods. The complexity and diversity of the road networks are significant for shaping vibrant streets. In Hong Kong’s ongoing construction program of large-scale public housing estates, the design prioritizes the connectivity of pedestrian circulation to foster social interaction among residents and encourage the utilization of recreational facilities. In this study, an analytical framework is developed to interpret public housing estate spatial layout based on satellite imagery. It extracts road networks using neural networks and vectorizes results to analyze network integration around estates to predict social interactions. The aim of this process is to employ a machine learning workflow to analyze options for newly planned estates, where the design configuration can be further optimized based on its potential to stimulate social engagement and community interaction. Due to the scalability and universality of the method, the research can contribute to improved road networks and sociable housing complexes in Hong Kong, or in other international cities of similar density and vibrancy.

summary	Sound, an often easily overlooked part of the urban composition, plays a crucial role in urban studies regarding how people perceive urban acoustic environments. Influenced by variable natural and artificial acoustic elements, the multi-level nature of urban soundscapes reflects multidimensional urban characteristics and thus demands thorough investigations. Unravelling the acoustic complexity and understanding its influence on public spaces' popularity will benefit the interpretation of urban soundscapes and help to build a more vibrant public life. In this paper, we utilize DepthMapX and QGIS to select specimen sites for further investigation. The behavioural analysis is performed through principle components analysis (PCA) and K-Means analysis based on data obtained within the city of London. This project seeks to develop digital strategies to investigate the relationship between urban public spaces and their soundscapes: to infer the correlation between people's emotions and the richness of urban environments. Through integrating machine-learning analytic approaches into visualizing how citizens perceive or experience the urban sound environment, our research aims to positively assist and inform urban practitioners in planning and designing more benign acoustic environments.

title	Designing a Systematic Experiment to Investigate the Effect of Ambient Smell on Human Emotions in the Indoor Space; Introducing a Mixed-Method Approach
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_20
summary	Studies have indicated that built environments affect all aspects of human life such as emotion, perception, behavior, health, and well-being (Cooper et al. 2011). Built environments are formed from the combination and juxtaposition of visible and invisible environmental variables. In recent years, common techniques such as virtual reality, augmented reality, digital twins, and artificial intelligence have enabled researchers in the field of architecture and urban design to simulate environmental conditions to investigate the impacts of environmental variables on humans. However, the studies conducted in this field of human comfort are mostly focused on the impact of environmental variables such as form, temperature, humidity, and sound, and in fewer studies, up-to-date methods and technologies have been used to simulate and investigate the impact of smell on humans. Most of the studies that have investigated the effect of ambient smell on humans, carried out in the discipline of architecture and urban design, have used traditional tools and methods (questionnaire, interview, observation) rather than advanced technology and tools drawing on neuroscientific knowledge and technique to measure the effectiveness of the ambient smell on human. They have used unmasked scents or real-world environments rather than being able to simulate environmental conditions. This article highlights the significance and necessity of employing simulation methods to investigate the impact of environmental smells on humans. Additionally, it presents the methodology of an experiment for studying the effect of indoor environment smells (with a case study of an office environment in the initial phases) on human emotions, utilizing a mixed-method approach. Analysis of some parts of the data from this experiment showed that exposure to the fragrance of the jasmine flower pleasant (flower) and the odor of the rotten orange peel (unpleasant) can cause changes in the electroencephalography (EEG) power across different bands among participants.

title	Urban Morphology and Solar Incidence in Public Spaces - an Exploratory Correlation Analysis Through a CIM System
source	García Amen, F, Goni Fitipaldo, A L and Armagno Gentile, Á (eds.), Accelerated Landscapes - Proceedings of the XXVII International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2023), Punta del Este, Maldonado, Uruguay, 29 November - 1 December 2023, pp. 1655–1666
summary	The walkability of open spaces has been highlighted in current discussions about the production of designed environments in urban contexts (Matan, 2011). To contribute to this theme, this work selects the environmental comfort of open spaces as its element of study. The production of urban space was investigated, specifically in regard to urban morphology, understanding that city design directly influences environmental comfort (Jacobs, 1996). This work addresses the geographic context of low latitudes, specifically in hot and humid climate zones of Brazil, and, in this context, according to NBR 15220 (national performance standards), shading is one of the main comfort strategies, so solar incidence was the approached environmental phenomenon. Thus, this work presents a digital system that performs exploratory analysis on the correlations between urban form indicators and environmental performance indicators, specifically solar incidence. The method consists of three steps: urban form modeling (1), indicator measurement (2) and correlation analysis (3). In the first stage, different spatial sections of a city in Brazil were represented in the digital environment (1). This work’s implementation instrument is based on a City Information Modeling framework (Beirao et al., 2012). Visual Programming Interface (VPI) and Geographic Information Systems (GIS) tools were used, in addition to a Relational Database Management System (RDBMS). Then, for each urban clipping, the values of morphological indicators and the incidence of solar radiation were measured (2). Based on the values of the indicators, an exploration of their correlation was carried out by statistical methods (3). The results of the correlation analysis and their correspondent scatter plots are presented. Finally, possible applications of the results for the creation of prescriptive urban planning systems are discussed, seeking to promote a sustainable urban environment.

summary	Seeking to investigate the environmental variables that most influenced people's perceptions of urban public space, this study evaluates the effects of four variables through virtual urban scenarios and statistical analysis. The variables investigated were a) building setback, b) building usage and facade treatment, c) visual permeability of the barrier and, d) conservation of the façade. Nine different scenarios were presented to 42 students of architecture and urbanism, and four professionals that evaluated each of them through semantic differential questionnaires. The data was analyzed using a Friedman test and showed and effect for all four variables. Facade conservation was the variable that had an effect on the largest number of attributes studied, followed by building setback. Type of use and visual permeability affected fewer attributes. The results of the study can be useful to guide the planning and design of public spaces that are more attractive and satisfying for users, in addition to promoting related research.

title	The Hierarchical Location-Allocation Model for Primary Health Care Facilities Planning: A Selected Case Study in Amman
source	C+++: Computation, Culture, and Context – Proceedings of the 11th International Conference of the Arab Society for Computation in Architecture, Art and Design (ASCAAD), University of Petra, Amman, Jordan [Hybrid Conference] 7-9 November 2023, pp. 400-423.
summary	This study integrates a procedural approach to Primary Health Care Facilities (PHCFs) planning in Jordan, by combining Public Facilities Urban Planning Principles and Guidelines with a Hierarchical Location Allocation Model (HLAM) through the Process of Systematic Urban Planning suggested by Chadwick (1969) and Lee (1973). The objective of this study is to offer planners and decision makers a framework that can help them make decisions when selecting the locations for PHCFs. The study methodology is based on an analytical approach to analyse data, and then an experimental approach was employed to investigate the relations between the study variables to test the study hypothesis and to answer the key questions. The study highlights the healthcare system of Jordan, and it suggests PHCF planning standards. The study also highlights the principles of public facilities urban planning, and the use of models in urban planning particularly HLAM. Then, the study introduces “HLAM Application” as a study tool which was built particularly to solve HLAM for primary healthcare system of Jordan.The results indicate that PHCF planning in Jordan suffers from the low efficiency of the spatial distribution in conformity with the population density and the max distance to the nearest healthcare facility and does not fulfill the public facilities urban planning principles and the hierarchy system of PHCF adopted by the Ministry of Health.

summary	This study investigates the user's relationship with seating and its influence on the use of public spaces, focusing on the physical characteristics of seating: elements (backrest, armrest), shape (straight, curved), configuration (individual, collective), materiality (concrete, wood) and arrangement (side by side, perpendicular) though nine perception scales: comfort, pleasantness, interest, accessibility, refinement, price, style, friendliness, and similarity. For this study, stimuli were constructed through parametric modeling and photomontages, printed, and presented in site to participants, and it was conducted in an urban park in the city of Santa Maria, Rio Grande do Sul, Brazil, and it had the participation of 62 users of the space. Results indicate that backrest, side-by-side arrangement, and concrete material are within the preferences of the research participants.

summary	AI-assisted urban design software can streamline development processes by focusing on massing studies that satisfy legal provisions, providing high-quality and optimized estimations. However, designer-oriented technical tools for urban and architectural design prevent some stakeholders, such as policymakers and citizens, from participating in the design process, potentially leading to poorly negotiated proposals, delaying their execution, and causing social deadweight loss. This paper presents Speedy Facade, a framework to enable the active participation of all stakeholders, by converting human verbal descriptions into textured 3D building facades inside traversable urban models. Speedy Facade consists of (1.) an interactive user interface for verbal inputs and keyword selections, (2.) an augmented reality environment with projected façade reference images that can be modified by mask projection selections and regenerations, and (3.) an editable three-dimensional model for experience and design development. The paper discusses the implementation approach and contribution to the urban design process of this work and showcases its applications, and prospects for future expansion.

doi	https://doi.org/10.52842/conf.ecaade.2023.1.417
summary	The research presented in this paper focusses on the prefabrication of wood building systems using human craft and robotic machines as equal actors in collaborative fabrication processes. It uses self-developed components such as a data managing framework system to generate and exchange fabrication data between the design elements and the fabrication environment. Human robot collaboration via augmented reality (AR) technology is facilitated through a software framework and applied in the prefabrication of timber structures. Based on previous research, this iteration uses the concept of multi-actor fabrication and extends the number of human actors in the fabrication process. A case study was conducted for the collaborative fabrication of a timber structure. Five actors (four humans and one 7-axis robotic system) received instructions based on their individual skill set and collectively manufactured a timber structure in an organized workflow.

summary	PM2.5 has become a significant factor contributing to the haze outbreak in mainland China, which has negative impacts for public health. The current agility of CFD-based modelling to reveal in real-time the changes in PM2.5 concentrations in response to (proposed) changes in urban form limits its practical applications in the design processes. To support urban design for better air quality (AQ), this study presents a machine learning approach to test: (1) that the spatial distribution of PM2.5 concentrations measured in an urban area reflects the area’s capacity to disperse particle air pollution; (2) that the PM2.5 concentration measurements can be linked to certain urban form attributes of that area. A Convolutional Neural Network algorithm called Residual Neural Network (ResNet) was trained and tested using the ChinaHighPM2.5 and urban form datasets. The result is a ResNet-AQ predictor for the city centre area in Beijing which had one of the highest air pollution levels within the Beijing-Tianjin-Hebei region. The urban area covered by the ResNet-AQ predictor contains 4,000 grid cells (approx. 25.3 km x 25.3 km), of which 1,200 (30%) cells were selected randomly for testing. The ResNet-AQ prediction accuracy achieved 87.3% after 100 iterations. An end-use scenario is presented to show how a social housing project can be supported by the AQ predictor to achieve better urban air quality performance.

summary	Even with the difficulty of implementing NBS for EbA as a solution due to the inconsistent documentation of past experiences and heavy dependence on local, ecological and social conditions, would it be possible to implement NBS that incorporate the needs of each place? This paper shows the experience of the implementation of a NBS in an urban area, in the context of “Present City Project”, using parametric modeling to simulate outcomes during the planning process. The algorithm used inputs to develop a multi-criteria analysis capable of translating urban complexity. The result of this process is a comprehensive map identifying the most efficient locations for implementing GI based on the provided data and the streets suitable for interventions with NBS as well as their water absorption capacity. Throughout the process of submitting the "Present City Project," the algorithm played a pivotal role as an essential tool for raising public awareness.

doi	https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_17
summary	This study constructs a multi-agent behavior simulation model to explore the quantitative simulation method of waterfront public space. Taking 6 waterfront public space samples along the Huangpu River in Shanghai as research objects, this study first collects environmental data and pedestrian behavior data through field survey, and then analyzes and processes the data to obtain the Spatial Attraction Weight (SWA) that expresses the relationship between pedestrian behavior and spatial elements. Then, based on the Anylogic platform, the pedestrian agent particles expressing people’s characteristics are placed into the simulation environment based on the social force model. They interact in real time to dynamically simulate the pedestrian’s behavior. Finally, fitting verification of the preliminary model is carried out. The qualitative comparison and quantitative correlation analysis are combined to enhance the accuracy. The behavior simulation model of waterfront public space built in the study can more realistically represent the pedestrian's behavior. It can realize the scientific prediction of the future use of waterfront space and provide more detailed reference for problem diagnosis and optimization.

title	A shape grammar for the spontaneous occupation settled in fishing villages: The case of Garopaba, Brazil
source	International Journal of Architectural Computing 2023, Vol. 21 - no. 1, pp. 158–187
summary	This work presents the second stage of a larger study which conducted the elaboration of a shape grammar based on the analysis of the remaining fishing villages in the Santa Catarina State, Southern Brazil. The architectural and formal structure of the villages provide a perspective of the constructive methods and features embedded in the spatial arrangements and represent a local cultural heritage site. The aim of the present work relies on unraveling its spatial resources using a shape grammar approach, in order to contribute to the preservation of a distinct culture, and is intended to be used to safeguard its formal language planning. Also, through the analytical grammar, it would be possible to contribute in framing design guidelines regarding the remaining villages, to keep it steady on the traditional context, safeguarding its peculiar character. As such, the method in this body of work considered the analysis resulting from the first stage, in order to develop an analytical shape grammar using Garopaba village as a case of study. This stage involved the establishment of a formal language for the analytical grammar, consisting of initial form, vocabulary, families, and spatial relations, and thus, a series of rules emerged, decoding the composition arrangements. The results involved the verification of the considered parameters, confirming the existence of spatial patterns. Thus, it was possible to conclude that the grammar contributes to identifying the occupation process occupation and the spatial patterns which underlies an artisanal fishing village. Also, the grammar allowed the creation of urban compositions similar to the structure of traditional fishing communities in Santa Catarina, generating different discussions regarding the analytical approach towards fishing villages arrangements, compared to the examples studied, specifically, in Garopaba city

The digital twin aims to analyze the relationship between urban density, mix of uses and urban patterns, focusing on the counting of people on the sidewalks. The prototype uses ultrasonic sensors and an Arduino Uno board. Three measurement points with different patterns of occupation and land use were selected. Preliminary results revealed limitations in the sensors, especially in complex passing patterns. The roughness of the surfaces also interfered with the readings. Proposed improvements include the addition of a third sensor and the use of a tripod mount. The study contributes to the understanding of urban walkability and may provide useful information for sustainable urban planning in other cities.

summary	The intent of this research is to study potential improvements and optimizations in the context of robotic fabrication paired with Augmented Reality (AR), leveraging the technology in the fabrication of the individual part, as well as guiding the larger assembly process. AR applications within the Architecture, Engineering, and Construction (AEC) industry have seen constant research and development as designers, fabricators, and contractors seek methods to reduce errors, minimize waste, and optimize efficiency to lower costs (Chi, Kang, and Wang 2013). Recent advancements have made the technology very accessible and feasible for use in the field, as demonstrated by seminal projects such as the Steampunk Pavilion in Tallinn, Estonia (Jahn, Newnham, and Berg 2022). These types of projects typically improve manual craft processes. They often provide projective guidelines, and make possible complex geometries that would otherwise be painstakingly slow to complete and require decades of artisanal experience (Jahn et al. 2019). Building upon a previously developed robotic tube bending workflow, our research implements a custom AR interface to streamline the bending process for multiple, large, complex parts with many bends, providing a pre-visualization of the expected fabrication process for safety and part-verification purposes. We demonstrate the utility of this AR overlay in the part fabrication setting and in an inadvertent, human-robot, collaborative process when parts push the fabrication method past its limits. The AR technology is also used to facilitate the assembly process of a spatial installation exploring a unique aesthetic with subtle bends, loops, knots, bundles, and weaves utilizing a rigid tube material.

summary	This paper presents early-stage research about the role of gamification in experiencing cultural heritage strongly within the sociological context, specifically focusing on the transformation of the old orphanage located in the historical city center of Mardin. The study acknowledges the significance of the old orphanage as an architectural heritage exemplar, built of natural Mardin stone, situated within a unique historical and archaeological urban environment. However, it recognizes the challenges of preserving the building's heritage value, which necessitate surpassing the superficial restoration methods applied to adapt it into a hotel. The primary motivation of this research is to develop a method for creating a navigable and interactive virtual replica of the orphanage, centering on the processes and outcomes of transferring its heritage value. To achieve this, the paper initially outlines the documentation and analysis procedures employed, utilizing photogrammetry to capture the past and current states of the orphanage. Subsequently, participants engage with a gamified and realistic digital replica of the orphanage, involving task-based interactions and scenario-based experiences. The paper concludes by presenting preliminary results concerning participant reactions to the initial virtual model, delivered through a VR device. By raising awareness about the significance of restoring and preserving historical heritage, this study aims to positively impact the domains of tourism, education, and conservation. Furthermore, it intends to shed light on future research opportunities in the field of digital cultural heritage.
