title	Behaviour Simulation Optimization Based on the Influence of Microclimate on Crowd Perception – A Case Study of Urban Waterfront Public Space
doi	https://doi.org/10.52842/conf.caadria.2023.2.019
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. 19–28
summary	The outdoor behaviour is usually influenced by space and environment. Previous studies on behaviour simulation of outdoor space always focused on the influence of two-dimensional space, but did not take the microclimate perceived into account. However, the microclimate of outdoor public spaces has a strong influence on the activities, which makes the subsequent behaviour simulation results unable to fit well with the reality. Therefore, this research attempts to integrate the influence of space and microclimate perception of crowd into behaviour simulation system. Firstly, we explored the laws of behaviour in terms of seasons, weekdays/weekends, and time slices. Secondly, the multiple linear regression equations of the influence of space and microclimate on behaviour were established. In addition, combining the laws and models with the social force model, a behaviour simulation model in public space under the joint influence of microclimate and space was established. Finally, a comprehensive workflow combining microclimate simulation and behaviour simulation was proposed. The research promoted the application and development of behaviour simulation technology from strong-purpose behaviours to weak-purpose and non-purpose behaviours. Moreover, starting from human behaviour and perception, it provides support for the optimization of urban public space from the bottom up.

title	A Hybrid Generative Design Method for Optimizing Energy Efficiency in Complex Built Environments
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. 847-862.
summary	Architectural design issues in Complex Built Environments have drawn significant attention from contemporary architects. In the conceptual design phase, previous architectural design methods only accentuate the form and function of the design outcome while neglecting whether the result meets the energy efficiency specifications in the current built environment. Therefore, discovering a new method of architectural design by considering the impact of different design elements/modules on the whole life cycle of the building would meet the need for energy efficiency and emission reduction. This paper serves as a demonstration, utilizing the future Faculty of Architecture, Building and Planning (ABP) building at the University of Melbourne’s Fishermans Bend innovation campus as a prime example, to evaluate the effectiveness of the SimScale Workbench in creating an energy-efficient parametric building information model and generating Integrated Environmental Solution (IES) simulations to analyze the changes in the energy consumption ratio throughout the whole year. By proposing indoor performance targets based on wind and thermal environment analysis, Architects could use hybrid generative building design methods to formulate design strategies for the complex-built environment from an energy efficiency-driven perspective.

title	High-performance Spatial Composite 3D Printing

summary	This project explores the advantages of employing continuum material topology optimization in a 3D non-standard lattice structure through fiber additive manufacturing processes (Figure 1). Additive manufacturing (AM) has gained rapid adoption in architecture, engineering, and construction (AEC). However, existing optimization techniques often overlook the mechanical anisotropy of AM processes, resulting in suboptimal structural properties, with a focus on layer-by-layer or planar processes. Materials, processes, and techniques considering anisotropy behavior (Kwon et al. 2018) could enhance structural performance (Xie 2022). Research on 3D printing materials with high anisotropy is limited (Eichenhofer et al. 2017), but it holds potential benefits (Liu et al. 2018). Spatial lattices, such as space frames, maximize structural efficiency by enhancing flexural rigidity and load-bearing capacity using minimal material (Woods et al. 2016). From a structural design perspective, specific non-standard lattice geometries offer great potential for reducing material usage, leading to lightweight load-bearing structures (Shelton 2017). The flexibility and freedom of shape inherent to AM offers the possibility to create aggregated continuous truss-like elements with custom topologies.

title	Exploring Building Typologies and their Socioeconomic Contexts: Compositional Insights from Large-Scale-Text-to-Image Models
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 979-8-9891764-0-3].

summary	This study utilizes large-scale-text-to-image (LLI) models to investigate possibilities to describe building types data-centric. With the introduction of ""data-centric typologies"" we hope to challenge traditional architectural classification systems, while reviving type as an architectural strategy to link socio-economic contexts to the physical form of a place. By examining artificial intelligence (AI)-generated images of various city buildings, the research explores compositional characteristics, realism, and model limitations. We generated and segmented a synthetic dataset of 15,000 images into individual building segments, conducting a statistical analysis of compositional features across 500 cities. Despite dataset biases and limitations, our results indicate that synthetic databases provide a deeper analytical basis than traditional methods. The generated dataset alone paints forensic landscapes of locales that are not typically showcased. Particularly from a pedagogical perspective, data-centric investigations can serve as a valuable tool for illustrating the diversity of cities and living modes. The findings show that socio-economic attributes, like quality of life, are more closely tied to neighborhoods or projects than entire cities. Consequently, architectural typologies are most effective at a human-ori- ented scale, interfacing city with architecture.

title	Centripetal Clay Printing : Six-Axis Prints for Habitat Column

summary	Gottfried Semper, in his 1851 text The Four Elements of Architecture, famously classifies architecture into four elemental parts: the hearth, the roof, the enclosure, and the mound, describing the role of the last three to be the “defenders of the hearth’s flame against the three hostile elements of nature (Semper 2011).” Modernity has witnessed the role of enclosure evolve to that of a sealed envelope, or one which meticulously separates the ‘natural environment,’ from the internally regulated environment as part of modern comfort. The post-modern advent of the rain-screen has further separated the layer of exteriorized cultural expression from the structuring envelope, removing the ornamental aspect of Semper’s enclosure, from the enclosing layer. This habit of casting the natural processes out of our building envelopes has resulted in the rapid depletion of space for biodiversity within our cities. Joyce Hwang in her essay “Living Among Pests,” has suggested that the needed reconnection of biodiversity with our urban buildings will force a re-examination of “facade articulation to take on more responsibilities. Ornament will become performative” (Hwang 2013).

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 979-8-9891764-0-3]. 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	Reversed 3D Printing with Robotic Technology for Structure Nodes
source	ACADIA 2023: Habits of the Anthropocene: Scarcity and Abundance in a Post-Material Economy [Volume 1: Projects Catalog of the 43rd Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 979-8-9860805-8-1]. Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 214-219.
summary	This research focuses on the creation of complex structure nodes using a reversed robotic 3D printing technique (Figure 1 and 2), specifically utilizing FDM (Fused Deposition Modeling) technology. Traditional 3D printing involves building objects layer by layer on a stationary platform. Robotic 3D printing employs a similar method, with a plastic extruder as the end effector of a 6-axis robot. Compared to a conventional 3-axis 3D printer, a robotic 3D printer offers greater flexibility due to its inverse kinematics. For example, a 6-axis robot can directly build models on curved surfaces with varying layer thicknesses based on the geometry. However, when it comes to creating structure nodes with branches splitting in different directions, both work modes have certain drawbacks:

title	Multi-Objective Optimization of Gymnasium Layout Based on Genetic Algorithm – Balance of Energy Consumption and Indoor Thermal Comfort
doi	https://doi.org/10.52842/conf.caadria.2023.2.603
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. 603–612
summary	Multi-functional complexes have gradually become a new trend in the development of gymnasiums. Different types of layout patterns, such as space combination, space depth ratio, and atrium forms, will have a more obvious impact on the indoor energy consumption and comfort of the gymnasium. The genetic algorithm SPEA-2 and the Pareto optimal multi-objective optimization workflow were introduced in this study to help architects improve the layout design of the gymnasium in the early design stage. This workflow can optimize radiation energy load and indoor thermal comfort by adjusting plan parameters. The study combined with test cases to explore the Pareto frontier solution set (30 generations) of the layout morphological parameters?LMP? under different layout combination modes, and to explore in which combination mode, the energy load and the indoor thermal environment comfort can achieve a relative balance. Part of the optimal solution is selected for quantitative analysis of the performance improvement ratio, so as to verify the simulation test results.

title	Topology optimization of shell structures in architectural design
doi	https://doi.org/https://doi.org/10.1007/s44223-023-00042-z
source	Architectural Intelligence Journal
summary	Free-form architectural design has gained significant interest in modern architectural practice. Due to their visually appealing nature and inherent structural efficiency, free-form shells have become increasingly popular in architectural applications. Recently, topology optimization has been extended to shell structures, aiming to generate shell designs with ultimate structural efficiency. However, despite the huge potential of topology optimization to facilitate new design for shells, its architectural applications remain limited due to complexity and lack of clear procedures. This paper presents four design strategies for optimizing free-form shells targeting architectural applications. First, we propose a topology-optimized ribbed shell system to generate free-form rib layouts possessing improved structure performance. A reusable and recyclable formwork system is developed for their effective and sustainable fabrication. Second, we demonstrate that topology optimization can be combined with funicular form-finding techniques to generate a rich variety of elegant designs, offering new design possibilities. Third, we offer cost-effective design solutions using modular components for free-form shells by combining surface planarization and periodic constraint. Finally, we integrate topology optimization with user-defined patterns on free-form shells to facilitate aesthetic expression, exemplified by the Voronoi pattern. The presented strategies can facilitate the usage of topology optimization in shell designs to achieve high-performance and innovative solutions for architectural applications.
