summary	Residential buildings are responsible for a considerable share of energy consumption and carbon emission. To decarbonize by 2050, as agreed in the Paris Climate Accord, immediate action for lowering the environmental impact of the building sector is needed. Environmental building design is a promising path, particularly during the early-stage design when design decisions are more impactful and long-lasting. One of the initial steps in the building design process is site assessment, during which the building context and environmental factors are to be evaluated. The surrounding environment plays a critical role in the building's energy performance and the thermal, visual, and acoustic comfort of its occupants. We choose quantitative approaches to study the complexity of the environmental design with respect to the building context by analyzing environmental cues embedded in architectural drawings that have been given less attention in previous studies. Nevertheless, disclosing site-specific geolocation data of buildings, more specifically residential type, is often challenging due to privacy issues. Therefore, there is a lack of context-related metadata in the current architectural datasets. Whereas simulation data are more available and provide a wealth of contextual information, however, it is less appealing for architects to interpret design patterns from extensive simulation figures. This research focuses on developing an interpretable visualization of the building’s micro-climate context from environmental simulation data without direct access to the geolocation of the site. The environmental context visualization is created from daylight, view, and noise from 3088 multifamily housing presented in the Swiss Buildings data set, merely based on available simulation data. The presented pipeline in this study facilitates the employment of existing simulation data in the built environment datasets while circumventing the concerns associated with geolocation data exposure. Further, the generated visualizations may be used to develop computer vision models for environmental assessments of building layout design.

title	Encoding Urban Ecologies: Automated Building Archetype Generation through Self-Supervised Learning for Energy Modeling
source	ACADIA 2023: Habits of the Anthropocene: Scarcity and Abundance in a Post-Material Economy [Volume 2: Proceedings of the 43rd Annual Conference for the Association for Computer Aided Design in Architecture (ACADIA) ISBN 979-8-9860805-9-8].

summary	As the global population and urbanization expand, the building sector has emerged as the predominant energy consumer and carbon emission contributor. The need for inno- vative Urban Building Energy Modeling grows, yet existing building archetypes often fail to capture the unique attributes of local buildings and the nuanced distinctions between different cities, jeopardizing the precision of energy modeling. This paper presents an alternative tool employing self-supervised learning to distill complex geometric data into representative, locale-specific archetypes. This study attempts to foster a new paradigm of interaction with built environments, incorporating local parameters to conduct bespoke energy simulations at the community level. The catered archetypes can augment the precision and applicability of energy consumption modeling at the different scales across diverse building inventories. This tool provides a potential solution that encourages the exploration of emerging local ecologies. By integrating building envelope characteristics and cultural granularity into the building archetype generation process, we seek a future where architecture and urban design are intricately interwoven with the energy sector in shaping our built environments.

title	Exploring the Integration of Mid-Journey AI for Architectural Post-Occupancy Evaluation - Prioritizing Experiential Assessment: Case Study of the Egyptian Museum and National Museum of Egyptian Civilization
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. 518-550.
summary	The post-occupancy evaluation (POE) process, traditionally reliant on subjective user feedback and observations, has evolved in response to global concerns like climate change and sustainability. This shift towards greater objectivity and quantification reflects an increased focus on precise measurement of environmental and performance metrics. Consequently, architectural assessment is now more quantitatively oriented, moving away from a predominantly experiential emphasis. This research investigates the integration of the emerging AI tool Mid-journey into the POE process, specifically targeting the evaluation of experiential aspects in architectural design. It proposes that AI tools can be instrumental for architects and evaluators by translating user feedback into visual representations and conceptual insights. The study aims to initiate a discourse on the role of text-to-image models in assessing user experiences, potentially becoming integral to the design and concept generation process. The research combines quantitative methods like surveys and AI-driven experiments with qualitative approaches such as observations and interviews to offer enhancement proposals for Egyptian museums, comparing traditional POE solutions and frameworks with new proposed framework that incorporates AI-generated alternatives. This study emphasizes the dual role of museums as artifact custodians and platforms for public education about ancient cultures. It highlights the imperative to transform Egyptian national museums into immersive learning environments, rather than mere storage spaces. The aspiration is to create museums that securely display and preserve artifacts while fostering educational engagement in preserving our shared history.

title	An industry case study using parametric modelling to facilitate Passive House design
source	International Journal of Architectural Computing 2023, Vol. 21 - no. 3, 421–444
summary	A Passive House’s airtight, well-insulated building envelope can lower operating energy use but also increase the possibility of overheating during the summer. The Passive House Planning Package (PHPP) Excel modelling tool for Passive Houses treats the entire structure as a single thermal zone; this simplification may be in part to blame for the instrument’s poor capacity to forecast the risk of overheating. The current study offers new information on two subjects. First, we compare PHPP’s overheating evaluation method to that of the Chartered Institution of Building Services Engineers’ (CIBSE) ‘TM59’ standard, which involves conducting dynamic energy modelling at the room level. Our results support the idea that PHPP underestimates overheating. In the analysed case, glazing solar heat gain coefficient, and air change rate were some of the most crucial factors affecting compliance. Second, we highlight the usefulness of parametric design for compliance.

title	Designing for the Living Building Challenge: An Integrated Material Environment Visibility Framework for New Zealand Designers
source	Immanuel Koh, Dagmar Reinhardt, Mohammed Makki, Mona Khakhar, Nic Bao (eds.), HUMAN-CENTRIC - Proceedings of the 28th CAADRIA Conference, Ahmedabad, 18-24 March 2023, pp. 423–432

summary	To achieve rigorous performance in sustainability toward zero-carbon in the Built Environment, the New Zealand government also promotes Living Building Challenge (LBC) in design. The LBC seeks detailed material specifications till disposal with environmental impacts to measure sustainability in design and insists 75% of the project materials supply within 90 km of the project location. This study explored the constraints related to LBC material requirements and found the major barriers for designers are a) the sustainability imperatives namely red list and material lifetime are not considered by online material catalogue providers, b) no material data is shared among the primary stakeholders for acceptance and compliance evaluation, and c) no facility to identify the supply chain and suppliers within a certain distance of the project location. As a solution, this research designed a hybrid material catalogue having all possible material parameters classified into 5 major categories and developed an integrated material environment visibility framework linking the processes among the designers, contractors, suppliers, and the client. This proposed integrated framework provides a shared environment on material viewing, similar alternatives, accurate compliance evaluations in design, material suppliers availability, and other supply chain details at design stage itself. This new framework is currently under industry evaluation for compatibility, reliability, and industry professionals' acceptance.

title	Variability in Machine Learning for Multi-Criteria Performance Analysis
source	Immanuel Koh, Dagmar Reinhardt, Mohammed Makki, Mona Khakhar, Nic Bao (eds.), HUMAN-CENTRIC - Proceedings of the 28th CAADRIA Conference, Ahmedabad, 18-24 March 2023, pp. 149–158

summary	Parametric analysis is emerging as an important approach to building performance evaluation in architectural practice. Since architectural performance has many competing metrics multi-criteria analysis is required to deal effectively with the complexity. However, multi-criteria parametric analysis involves large design spaces that are expensive to compute. Machine learning is emerging as an important design space reduction method for multi-criteria analysis. However, there are many types of machine learning algorithms and architects can benefit from understanding which algorithms perform well on which tasks. Using a mid-rise commercial residential tower project this paper investigates three common machine learning algorithms for performance against three common performance metrics. The algorithms are multi-layer perceptrons, support vector machines, and random forests, while the metrics are site energy, illuminance, and a value function that combines them both. In addition, we seek to understand what factors are most impactful in improving algorithm performance. We investigate four impact factors namely sample size, sensitivity analysis, feature selection, and hyperparameters. We find that multi-layer perceptrons perform best for all three performance metrics. We also find that hyperparameter tuning is the most impactful factor affecting multi-layer perceptron performance.

title	Towards Adaptive Additive Manufacturing: Image-based Monitoring for Binder Jet 3D Printing of Coarse Composite Concrete Powders
source	ACADIA 2023: Habits of the Anthropocene: Scarcity and Abundance in a Post-Material Economy [Volume 2: Proceedings of the 43rd Annual Conference for the Association for Computer Aided Design in Architecture (ACADIA) ISBN 979-8-9860805-9-8]. Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 482-492.
summary	In the context of concrete 3D printing, this study explores the possibility of image-based monitoring for quality evaluation and improvement in powder-based binder jetting proce- dures for the use of coarse powders. The project's main goal is to create an integrated feedback loop that incorporates an image-based monitoring system into the printing process. This allows for real-time analysis for quality control and simultaneous incorpo- ration of coarse, composite powders. The overarching goal is to expand the possibility of binder jetting towards more diverse powder sources that would enable a circular economy and material reuse. This study investigates how coarser concrete powder and composite mixing ratios affect the printing process, thus laying the groundwork for the future use of hybrid materials instead of just using homogeneous standard powders. In this framework, image-based monitoring aids in more adaptive printing processes in addi- tive manufacturing, which will ultimately help us create 3D-printed structures that are produced with higher accuracy and sustainablility. These developments will also signifi- cantly impact 3D concrete printing in building applications, encouraging innovation and better performance in the additive manufacturing sector.

title	A Critical Review on Research Themes and Trends in Green BIM for AEC Sector
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. 899-916.
summary	Green BIM is an emerging concept in the architecture, engineering, and construction industry that combines Building Information Modeling (BIM) technology with sustainable design principles. This approach emphasizes the importance of integrating green strategies into the design and construction process to improve the environmental performance of buildings. It enables designers, architects, engineers, and contractors to analyze the environmental impact of building materials and systems, simulate energy performance, and optimize the use of resources. The aim of the study is to conduct a bibliometric research and systematic analysis on the concept of 'green BIM'. Web of Science database was used to search for publications containing the term 'green BIM'. 252 relevant publications from the fields of construction building technology, architecture, and urban studies were analyzed. It evaluates research themes and trends in Green BIM in terms of publication and citation numbers, research areas, document types, journals, conferences, and books where publications were published, numbers of publications by country, author and co-authorship analysis, and keyword analysis. The keywords were divided into 9 clusters in the VOSviewer and each cluster was examined under a separate title. These titles are urban design, visual programming, design & construction, sustainability, energy efficiency, life cycle assessment, green BIM, project management and green building assessment. The results show that the most current keywords are being evaluated under the heading of urban studies. This situation highlights that, unlike other academic studies, priority is given to urban-scale applications of green BIM Moreover, apart from urban-scale studies, possible topics for academic research involve Life Cycle Assessment (LCA) and the integration of BIM in the LEED certification process. Currently, the industry and prominent publications prefer technical studies due to the extensive coverage of general inquiries.

title	A Generative Design Model for Demolition Waste Reuse

summary	Inefficient resource management and excessive consumption of resources have led to the depletion of natural resources and increased waste in landfills, as the construction industry being a major contributor to global waste with construction and demolition waste making up a significant portion of it. It is critical to find alternatives for reintegration and reuse of the construction. By incorporating recycled aggregates from demolition waste with rammed-earth, it is possible to generate a durable, healthy, highly reusable and sustainable alternative to the common building materials that have serious environmental impacts. This study takes previous research about the recycled aggregate incorporated rammed earth further with a design approach that uses a generative system that follows the rules based on the function, context and material. Final design is chosen from the generated design alternatives and the modules required for the production are prepared with the mixture of recycled-aggregate, cement and fly ash. Then the modules are combined with an interlocking system that offers a convenient, laborless production process. We aim to promote the wider use of the earthen structures by re-interpreting the design and production process by generating design alternatives with modules driven by shape grammars for the recycled-aggregate based rammed earth.

title	Augmented Reality Assisted Robotic: Tube Bending
source	ACADIA 2023: Habits of the Anthropocene: Scarcity and Abundance in a Post-Material Economy [Volume 2: Proceedings of the 43rd Annual Conference for the Association for Computer Aided Design in Architecture (ACADIA) ISBN 979-8-9860805-9-8]. Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 340-349.
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.

title	Biopolymer Composites in Circular Design: Malleable Materials for an Instable Architecture
source	ACADIA 2023: Habits of the Anthropocene: Scarcity and Abundance in a Post-Material Economy [Volume 2: Proceedings of the 43rd Annual Conference for the Association for Computer Aided Design in Architecture (ACADIA) ISBN 979-8-9860805-9-8].

summary	This paper examines temporality within material and architectural cascades. It takes point of departure in the perception of bio-based materials as abundant within the emerging framework of bio-based circular design, and the need for materials that can incorporate flexibility to local availability, ecological implications, and cost. In this paper we introduce a specific biopolymer composite composed of interchangeable constituent materials from agricultural waste streams, and describe the malleability of this material through the processes of material composition and robotic fabrication, and the re-activation of its thermoplastic properties. We examine the design opportunities this opens for cascading, and how processes of repair, refitting, and recycling of a malleable material create ongoing instabilities of the object that can be conceptually and practically exploited at both architectural and material levels. We identify and describe these opportunities within the context of ‘Radicant’, a 3D printed wall paneling system made from the bio-polymer composite. We also present a series of experiments that exemplify how the strategic localized reactivation of the printed material can ideate new architectural strategies of repairing, refurbishing, and recycling.

summary	This paper reviews existing research on the teaching of narrative architectural design and the creation of role-playing games (RPGs), with an interdisciplinary connection between them. The paper conducts a systematic review and analysis of 27 academic papers. These articles are selected from the academic database "Connected Papers" using the keywords "narrative architecture, architectural design teaching, narrative story, RPG creation." This database employs natural language processing technology to analyze the links and influencing factors among articles in different disciplines. We then performed a key review of a selection of 5 papers addressing the interdisciplinary application between architectural design teaching and RPG creation. The key papers content includes a discussion of the problems and solutions in the creation methods of narrative architecture and RPGs, aiming to crystalize the defects and advantages of both approaches. Our findings summarize the process of materializing narrative content in two different creative industries, discussing the challenges they face and the existing solutions. Drawing from the narrative architectural design teaching effects and RPG creation results presented in the literature, this paper summarizes the advantages of both practices. This allows us to provide a summary of the current industry progress and identify possible research gaps based on the present status of interdisciplinary applications between the two.

title	Space Architecture, Biotechnology, and Parametric Processes: Design through Assembly, Growth, and Fabrication Parameters in an Iterative Feedback Loop

Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 104-115.
summary	Resource scarcity in extraterrestrial environments, like the Moon or Mars, imposes limitations on construction, necessitating resource and energy optimization. To respond to these challenges, this paper explores the development of a parametric framework, bridging the fields of space architecture, biotechnology, and parametric processes, allowing for the development of energy and resource-efficient structural components. The foundation for the framework is built upon ongoing research conducted in collabo- ration with NASA Ames Research Center, focusing on a mycelium-based aggregation of Martian regolith for construction. Due to the nature of the material and targeted environ- ment, the proposed parametrization process is based on specific assembly, growth, and fabrication requirements. The framework incorporates a feedback loop between design, computational simulation, and physical testing. The interaction of multiple systems, imple- mented through an iterative process and hybrid design approaches, enable continuous design refinement. These systems incorporate inputs from the interconnected disciplines that pose challenges when evaluated separately. The paper recognizes the challenge of identifying crucial parameters and implicit actions, and bridging the gap between theory and implementation. It calls for further work on programming the parametrization frame- work, and integrating computational simulations and data evaluation. In emphasizing the interdisciplinary nature of future space exploration and architecture, this paper under- scores the significance of integrating diverse disciplines and technologies.

summary	Focusing on generating, using, and exploring color schemes and applying them to visual patterns, this paper questions how co-creation systems can support artists’ creativity in coloring and explore possible UX features for such systems. Through an applied research project, we demonstrate a prototype system, ColorCraft that incorporates mix-initiative interaction methods building on an extensive literature review and expert interviews. Through ColorCraft, we propose possible UX techniques for facilitating the generation of color compositions and assigning colors to visual patterns, allowing for the exploration of alternative pattern colorings. We aim to enhance co-creative processes and provide tool features for applying colors on patterns in, e.g., graphics design, architecture, and interface design. The formative evaluation of the prototype shows promising feedback and insights for improving coloring applications. The study contributes to our understanding of problem characterization of coloring, and the artists’ expectations from tools that will augment their creative exploration of pattern coloring.

summary	During the pandemic, virtual tests had to be implemented, which led to the forced incorporation of GeoGebra in geometry courses of Architecture and Design degrees, therefore enabling the treatment of subjects that were unthinkable with pen and paper. In this context, this work explores the possibilities of recreating commands of design software with mathematical expressions, using GeoGebra as an interface that can be easily applied in Math courses of the region. The result is a synthetic map of commands described in a mathematical language, which may work as a translation bridge between the worlds of Math and Software, thus contributing to the connection of Mathematics with both thought and practice of Design and Architecture.

title	Computational Optimization of Architectural Space Planning
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. 732-749.
summary	Automated space layout planning has been a long-standing problem in the field of computer-aided design. The challenge lies in generating an optimal space design that has a well-defined vision and a multitude of competing objectives and evaluation measures. Computational approaches assisted designers in exploring design solutions and fulfilling some non-geometric goals more effectively and efficiently. However, quantifying spatial qualities for computational representations is challenging, especially where a multitude of interrelated objectives are needed to be met, such as wayfinding, maximizing views to outside, maximizing visibility, and minimizing travel, alongside the functional relations of the spaces with each other. Moreover, there could be a change in these intended objectives, which requires space design adaptation. Thus, there is a need for more flexible, fast, and automated design tools to be used in the design process. This paper presents a framework to generate optimal architectural space planning solutions through an interactive design system that takes geometrical, topological, and performance goals and design constraints as input. This system is based on data structure representations combined with evaluation and optimization algorithms and a parametric representation. Through a theoretical and analytical inductive study of the previous research in this field, defined steps for a computational approach for space planning optimization was proposed by presenting architect-friendly tools and graphics to simplify producing realistic optimal solutions for the required space planning problems.

title	Multisource Analysis of Big Data on Street Vitality Using GIS Mapping and Deep Learning: A Case Study of Ding Shu, China
source	Immanuel Koh, Dagmar Reinhardt, Mohammed Makki, Mona Khakhar, Nic Bao (eds.), HUMAN-CENTRIC - Proceedings of the 28th CAADRIA Conference, Ahmedabad, 18-24 March 2023, pp. 565–574

summary	Urban vitality is the driving force behind sustainable urban development. As the most frequently used public space in cities, the enhancement of street vitality is of great significance for improving human-centred habitats. Based on multi-source big data, this study uses spatial and statistical analysis methods to explore the impact factors of street vitality. Through the quantitative evaluation of these factors, we propose corresponding strategies to enhance the vitality of the street. Firstly, the spatial elements of streets are extracted using deep learning algorithm based on the acquired street view images. Further, the impact factors of street vitality are demonstrated using statistical methods by combining multi-source data. We established an evaluation system based on the impact factors of street vitality, which can quantify and predict street vitality. In this way, we can propose vitality enhancement strategy for the street with lower vitality in a targeted approach. The feasibility of the process is demonstrated by using Ding Shu as an example. This study provides a basic framework for a people-centred approach to enhance street vitality based on big data. It also contributes to causal inference in urban problems.

title	An Evaluation of Sketching Processes in Physical and Immersive Environments

summary	This study focuses on the evaluation of the physical and immersive environments in the sketching process. We planned a comprehensive study on sketching spanning from paper-based and digital in the physical environment to virtual reality and augmented reality in the immersive environment. In this direction, we conducted experiments consisting of 8 participants. The experiments were carried out under the protocol analysis and design conversation elements method. The data collected were converted into linkography graphics and analyzed depending on the content and evaluation parameters. The comparison between physical and immersive environments revealed that the design movements were more effective and the design process was more productive in the immersive environment. When evaluating within the physical environment, it was seen that design productivity is more efficient in analog as opposed to digital. Regarding VR and AR for immersive environments, it was seen that establishing a relationship with physical reality in AR contributed positively on associating the sketching process with context compared to full virtuality in VR. This study has shown that AR contributes to the production of outputs that are more contextual and provides dimensional equality in sketching processes. While physical and immersive environments serve different purposes and user needs, it is evident that the active utilization of immersive environments for design purposes will become more widespread in the near future.

title	Exploring a circular economy solution space A comparative study to develop automated optimisation workflows supported by machine learning for circular design problems
source	International Journal of Architectural Computing 2023, Vol. 21 - no. 3, 404–420
summary	Embedding circular economy (CE) principles in early design requires iterative evaluation across multiple lifecycle phases, with trade-offs between objectives complicating the identification of best solutions. This paper puts forward methods to automatically discover diverse, yet well-performing solution types within complex multi-objective CE design optimisation models. Working with a parametric model derived from a furniture design for CE case study, a comparison is made between weighted-sum single objective optimisation and multi-objective optimisation augmented with clustered solution types targeted by the reference pointbased NSGA-II optimisation algorithm. Efficiency of optimisation, quality of results and distinctiveness of solution types presented by each method is compared in an effort to understand which will best assist designers to manage complexity in CE design. The generalisability of the presented methods to larger scale CE design problems is discussed and future areas of work on computational design for CE are extrapolated from the presented results

title	Fluency of Creative Ideas in the Digital Age: Exploring Emergent AI Influences on Design Methodology and Visual Thinking in Architectural Education
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. 815-832.
summary	Research has explored the concept of originality in visual thinking and architectural education, using different methods. The new state of Artificial Intelligence (AI) in architectural design represents another shift from traditional modes of architectural design and education, into a more authentic approach to the digital age. An experiment is designed to highlight the originality of this approach in design thinking and its futuristic trends and impact on education and creativity studies. The intent of the study we present here is twofold: one to revisit key design studies of design exploration and secondly to explore students' design activity while interacting with text-to-image diffusion machine learning (ML) generative models such as Midjourney, DALL-E and Stable Diffusion, as these might have the potential to change the way that architectural students approach the concept stages of designing projects and products. In addition, we are interested in how the new shift in interfaces and modes of stimulus will influence the students' design process and perceptions. Participants in the design process are final year students who had spent at least four years in a school of architecture and can be classified as semi-experienced designers. Further within the evaluation also lies a critique of the diffusion ML tools themselves as producers of architectonic images, rather than complete concepts for architecture that encapsulate spatial, formal, structural arrangements of elements.
