summary	How to rapidly obtain building density information in a large range is a key problem for architecture and planning. This is because architectural design or urban planning is not isolated, and the environment of the building is influenced by the distribution of other buildings in a larger area. For areas where building density data are not readily available, the current methods to estimate building density are more or less inadequate. For example, the manual survey method is relatively slow and expensive, the traditional satellite image processing method is not very accurate or needs to purchase high-precision multispectral remote sensing image from satellite companies. Based on the deep neural network, this paper proposes a method to quickly extract large-scale building density information by using open satellite images platforms such as Baidu map, Google Earth, etc., and optimizes the application in the field of building and planning. Compared with the traditional method, it has the advantages of less time and money, higher precision, and can provide data support for architectural design and regional planning rapidly and conveniently.

summary	As Chinese cities entering a so-called organic renewal era, building projects runs with much more constraints from high-density and high-rise surroundings. Such a situation makes the technical review in any urban planning bureau time-consuming and error-prone, which conflicts with the developers profits and citizens rights. This study introduces a preliminary system being developed for the planning bureau of Huangpu District, Shanghai. It has covered 21 code items among 44 computational ones of the local planning codes last year, which automatically generates technical reviews upon developers submissions. Due to the feasible level of BIM application in domestic projects, a set of strategic approaches, such as the standardization of CAD drawings and the reconstruction of an internal building information model, are adopted rather than developing the system on any BIM platform directly. Two examples of technical reviews about distance-checking between buildings and length-checking of facades are demonstrated, in which officers reached confidential judgments in seconds rather than several days conventionally.

summary	Experienced architects can quickly formulate high-rise conceptual designs that align with both the clients' needs and building codes through estimation and logical deduction. Usually, such empirical knowledge takes architects years of practice to accumulate. This research aims to externalize this empirical knowledge into generative design method, thereby aiding intern architects in quickly gaining the skills needed to conceive high-rise conceptual designs. We have developed a prototype program and a corresponding workflow, which can assist architects in generating and presenting high-rise designs featuring a rectangular plan. Additionally, when architects make adjustments to the building mass, the program can perform some preliminary verification on the new design.

summary	The signage design of any large-scale transportation building is vital to its passengers wayfinding experiences. Firstly, a set of passengers paths should be re-designed by signage designers according to the latest requirements, which always deviates from the initial ones in large-scale projects or inevitably updates during a long-term running. Afterwards, the path design has to be transformed into the layout and content of signboards manually. It is a time-consuming and error-prone process. This study introduces a human-computer hybrid workflow keeping the flexible path design in the hands of designers and leaving the following procedures to an algorithm, which automatically generates signboard contents ready for construction. It is proved efficient with more than 3000 signboards in the project of PVG Airport, Shanghai. Furthermore, the designer got an opportunity to optimize his path design through various alternatives, which impossible traditionally.

title	Scale Mismatching: Prevalent Compactness Indexes of Urban Form DO NOT Work in Computational Urban Design
doi	https://doi.org/10.52842/conf.caadria.2024.2.455
source	Nicole Gardner, Christiane M. Herr, Likai Wang, Hirano Toshiki, Sumbul Ahmad Khan (eds.), ACCELERATED DESIGN - Proceedings of the 29th CAADRIA Conference, Singapore, 20-26 April 2024, Volume 2, pp. 455–464
summary	This study systematically evaluates and compares the effectiveness of 9 prevalent indexes for measuring the compactness of building distributions at the meso-scale through comparative experiments. Experiments primarily employ an ideal sample with controlled variables, and superior indicators are further tested in actual urban areas. The assessment, grounded in sensitivity and consistency, adopts rigorous quantitative criteria and is compared against a baseline computed by cohesion evaluation based on graph (GCE). Research findings indicate: (a) when quantifying compactness differences in same scale regions: Directly employing GCE or the improved T* is recommended; (b) when comparing compactness differences in regions of diverse scales, GCE is recommended; if using ENN or ANN, supplementary evaluation is necessary; (c) in studies of urban morphology effects mechanisms, it is advisable to utilize GCE instead of T, as T presents collinearity issues with footprint density. None of the remaining indexes is recommended for the above scenario at meso-scale. This research distinctly reveals the limitations of prevalent compactness indexes at meso-scale and suggests superior alternatives.

title	A Review of Compactness Indexes of Form in Computational Urban Design
doi	https://doi.org/10.52842/conf.caadria.2024.2.325

summary	This study investigates the application and challenges of compactness indexes in computational urban design. It begins with a conceptual review and application analysis of six urban form compactness indexes, classified into four categories. The study then identifies several issues in their current application, including imprecise referencing conditions, interpretational discrepancies, and opacity in computational parameters. Using actual blocks in Shanghai as case studies, it further verifies that parameter settings significantly influence calculation outcomes. This work emphasizes the importance of rigorous analysis of index application conditions in block-scale morphological measurements to prevent biases in computational design results.

summary	Thousands of online virtual experiments are being developed by hundreds of National Virtual Experimental Teaching Demonstration Centers run by top universities in China. According to an analysis on the existing VR technologies accessible in market and the conditions of domestic universities, a "bounded adoption" strategy was raised by Tongji University, when it dealing with a daily teaching context. It puts the manpower and financial resources into the design of virtual experiments, so-called 'contents building', rather than equipment purchasing as before. After three new experiments built, an evaluation on their contributions to learning performance is conducted immediately, which tries to understand whether the strategy works and how to move on. As one of these experiments, learning a historic Chinese temple in an online way is compared with other four learning methods from traditional ways to hybrid ways. The result indicates that the VR technologies applied with the "bounded adoption" strategy have a positive coherence to high learning performance, especially in form oriented recognition task, which plays a key role in architectural education. Meanwhile, the current design of virtual task involving building process has to be improved.

summary	As a bridge between tangible models and digital counter parts in almost all the architectural applications with Tangible User Interface, converting point clouds scanned from objects into light meshes with key-features are essential in the human-computer interaction. In this paper, an algorithm based on topological rules is introduced, which focuses on computing a topological-right mesh from a point cloud scanned by a low-cost device in real time. Mesh faces are extracted by analyzing distribution of the normal vectors of neighbor point clusters and mesh vertexes are calculated according to the topological conditions of local surrounding faces. Such a final key-feature mesh has the largest geometric similarity and least vertexes to the tangible model at an architectural cognitive level, whose dimensional accuracy is at an acceptable level concerning the low-cost device used.

title	Measure the Evacuees’ Preference on ArchitecturalCues by CAVE
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	An evacuees’ preference prediction function on architectural cues are described here as a crucial part of the evacuation model to simulate how the evacuees search the route to exit according to the architectural information in the public underground space. The model is developed to evaluate the egress design in the initial space design stage and to provide the existing compositive evacuation models a support on the usage of architectural information. First the over simplification on the architectural information in the existing evacuation models is discussed. Then a list of so-called architectural cues and the related evacuation model are introduced, in which the evacuees always egress to the seen or remembered architectural cue with the highest preference in every step. The emphasis of the paper is put on the analysis of the preference function including the CAVE-based conjoint analysis research method, the experiment design and implementation of the virtual drill, and the estimation of the parameters from the collected choices. The preference function for five architectural cue pairs, Doorway-Doorway, Stair-Stair, Exit- Exit, Doorway-Stair, Exit-Stair is built from the choice data of nearly one hundred Chinese subjects.

title	A Comparative Study on Choice Modeling Framework for Evacuation Simulation

summary	A choice modeling framework for evacuation simulation is needed for a better understanding of the human choice behavior. Facing with the debate between bounded and full rationality, this study builds upon different frameworks and tests them on a same set of choice data collected through virtual evacuation experiment. After comparisons, it is found that there is no significant performance difference between the two kinds of rationality. Additionally, an algorithm comparing pairs of alternatives in choice process performs much better than an algorithm evaluating individual alternatives. An improved utility maximizing model framework and an overall performance decline similar as the forgeting curve are proposed. Finally, it is concluded that the proposed choice model comparing pairs with its great robustness under varying number of alternatives is a proper choice for evacuation simulation.

summary	In this research funded by NSFC (50408038), an agent-based simulation model is developed for the human evacuation behaviour determined by a list of so-called architectural clues in the environment. A research method is introduced with an application for one of these clue types called Doorway. A six-variable model and a related set of virtual scenes were constructed and implemented in a Head-CAVE system, in which 102 subjects were tested as in an evacuation game. With the binary logit regression analysis a utility function is estimated indicating how these variables affect human choice on any pair of doorways in a scene. Evidence was found that the distance from the decision point to the doorway is not always the most important factor as it is assumed in the other evacuation models.

title	Hybrid Fabrication. A free-form building process with high on-site flexibility and acceptable accumulative error
doi	https://doi.org/10.52842/conf.acadia.2018.082
source	ACADIA // 2018: Recalibration. On imprecisionand infidelity. [Proceedings of the 38th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-17729-7] Mexico City, Mexico 18-20 October, 2018, pp. 82-87
summary	Although digital fabrication has a booming development in the building industry, especially in freeform building, its further application in onsite operations is still limited because of the huge flexibility required in programming. On the contrary, traditional manual fabrication onsite deals perfectly with problems that always accompany fatal accumulative errors in freeform building. This study explores a hybrid fabrication paradigm to take advantage of both in an onsite freeform building project, in which there is a cycling human–computer interactive process consisting of manual operation and computer guidance in real time. A Hololens-Kinect system in a framework of typical project camera systems is used in the demonstration. When human builders perceive, decide, and operate the irregular foam bricks in a complex onsite environment, the computer keeps updating the current form through 3D scanning and prompting the position and orientation of the next brick through augmented display. From a starting vault, the computer always fine tunes its control surface according to the gradually installed bricks and keeps following a catenary formula. Thus, the hybrid fabrication actually benefits from the flexibility based on human judgment and operation, and an acceptable level of accumulative error can be handled through computer guidance concerning the structural performance and formal accuracy.

summary	In the field of architectural design, Diffusion-limited aggregation (DLA) has been widely adopted in the study of macroscopic urban terrains and structures. If we consider individual habitats as having the same gene as our city, the intrinsic nature of DLA provides interesting insights in emulating local interactions that take place at microscopic level. This paper takes the dynamics of the DLA to the smallest unit of designable space. Whilst Phase I focuses mainly on Euclidean constraints, Phase II looks at how such generative space can add complexity to an open office plan by allowing different physical attributes to interact with one another based on the company’s organizational chart.

summary	This study explores the feasibility of formulating cement-based 3D printing mortar by incorporating Yellow River sand as an aggregate. Through systematic testing of the printing performance of Yellow River sand 3D mortar with varying proportions, preliminary insights into a formulation suitable for 3D printing of Yellow River sand mortar have been elucidated. Concurrently, the investigation employs the prepared desert sand 3D printing mortar with a robotic platform and an autonomously developed storage-extrusion 3D printing tool head to conduct 3D printing experiments for the designed samples. This comprehensive process validates the feasibility of 3D printing utilizing Yellow River sand mortar. Moreover, this research broadens the utilization scenarios of Yellow River sand and introduces an innovative approach and methodology for dredging and silt removal in the Yellow River.

summary	Owing to cloud computing Virtual Reality (VR), a note PC or tablet with no necessity of high spec GPU can be used for sharing of a 3D virtual space in a synchronous distributed type design meeting. In this paper, in addition to sharing a 3D virtual spacefor a synchronous distributed type design meeting, we developed a prototype system that enables participants to sketch or make annotations and have discussions as well as add viewpoints to them. We applied these functions to evaluate an urban landscape examination. In conclusion, the proposed method was evaluated as being effective and feasible. Operation is limited with one person, and more optional shapes should be preparedin future work.

summary	Modular structures with repeating configurations are a common type of building that consists of identical unit components arranged in a specific way. Design reasoning for such structures is an unstructured and unique process that relies on the designer's intuition and rational reasoning. However, repetitive design movements often become time-consuming and energy-draining. In the era of artificial intelligence, a crucial question is whether machines can replicate the design reasoning behaviours of human designers. This research aims to integrate the strength of human unique capabilities, like creativity, intuition, and design skills, with machine-emulating creativity, applied in the modular structure design while addressing production efficiency. It has shown that the Agent can mimic the designer's stacking approach to modular structure design by utilising Generative Adversarial Imitation Learning (GAIL) and Proximal Policy Optimization (PPO). Such a co-intelligent design method facilitates the creation of diverse modular structures.

summary	In sports facilities, a grandstand is the structure which provides good sight quality and safety evacuation conditions for the spectators. Grandstand plays important functional and formative roles in sports facilities, and especially in large scale stadia. This paper argues the notion of shape grammar and its computer implementation will solve the difficulties in grandstand design. The authors identify the specific difficulties of grandstand design, then set the aims of the grammatical computer tool. Afterwards the shape grammar of grandstand design is formulated, and a computer tool is developed based on the grammar. At last, the paper discusses the application and usage of the grammar and the computer tool both in early design phase and design development phase with a design practice case study of a large scale stadium.

title	Construction Based on Man-Machine Collaboration: A Case Study of a Bamboo Pavilion
source	Hybrid Spaces of the Metaverse - Architecture in the Age of the Metaverse: Opportunities and Potentials [10th ASCAAD Conference Proceedings] Debbieh (Lebanon) [Virtual Conference] 12-13 October 2022, pp. 503-514
summary	With the development of advanced digital design approaches and mechanical facilities, architectural intelligence liberates conventional construction from conventional paradigms. Computational design and digital fabrication have achieved progress in space innovation, construction efficiency, and material effectiveness. However, those high-tech manufacturing techniques are not widely available in developing countries, where the locals used to carry construction experience from age to age in a nonacademic way. This study explored a collaborative workflow of complex structural design and machine-aided construction in Chinese rural areas. First, we designed a bamboo pavilion parametrically in an irregular site on a hill. Second, its primary structure was optimized based on determining critical load and earthquake resistance to meet local building codes. Then, before material processing, every bamboo component was numbered by algorithm, with its location and morphological data of length and radian calculated accurately on the construction drawings. In the transitional process from the conventional paradigm by experience towards man-machine collaboration, local workers' manual techniques helped minimize construction errors and improve details, which were not adequately predicted and considered beforehand. This study case suggested that respective advantages of both traditional and digital modes should be integrated and balanced based on collaboration between local construction workers and professional researchers, especially as a social role for future vernacular architecture practice.

summary	Virtual reality offers considerable promise with regard to facilitating the building process. A good example is the facilitation of communication between architects and building companies, sellers and buyers or between community planners and the general public. It is often thought that in order to utilise the potential of VR in, for example, the above-mentioned contexts, it is necessary to use fully fledged versions of VR, including stereovision and the possibility of controlling the VR show. However, if a model can also be presented on less advanced equipment and still interpreted in a way that is useful to the viewer it will be possible to distribute the model simply and effectively. This would make it easier to create a more democratic urban planning process compared with if specialised equipment needed to be used and special shows needed to be arranged. In this study we compared the experience of two VR models (a large indoor exhibition hall and an outdoor street in Gothenburg, Sweden) when presented with and without stereovision. When the experience was measured using the Semantic Environmental Scale (the SMB scale, developed by Küller, 1975, 1991), questions on the experience of presence and six other questions on the experience of the models, the results only revealed one indication that stereovision made a difference. This indication was the result for the SMB factor Enclosedness. Suggestions are presented for future research in this area.
