This study simulates wind effects on a standard tall building model as specified by the Commonwealth Advisory Aeronautical Council (CAARC). We generated data to enhance living conditions through passive flow control, which mitigates building weathering, reduces wind loads, and improves energy efficiency and natural ventilation. The research also aids building designers with robust numerical predictions. The validity of these results was confirmed by comparing drag coefficient (C_D) values with those from previous studies. The findings demonstrate that passive flow control significantly reduces wind-induced drag forces on the building at various angles of attack (α) by altering wind-induced pressures, reducing vorticity, and decreasing vortex shedding magnitudes. The objective was to identify the optimal placement of segmented cladding materials with desired gaps between segments to allow airflow to influence temperature variations when exposed to wind at 293 K and a heat flux of 500 W/m² at wind speeds of 1, 2, and 4 m/s (Reynolds numbers of 5.2 × 10³, 10.4 × 10³, and 20.8 × 10³). Using 2D numerical analysis, twenty-four different facade and building model combinations were simulated. This study offers practical guidance on facade selection and positioning to optimize wind resistance and enhance the livability and functionality of building environments.

In the past decade, the construction speed of high-rise office towers worldwide has exhibited explosive growth. The unique morphological characteristics of high-rise office towers result in higher shape factors and relatively larger thermal loads. The traditional workflow of “design-evaluation” in the early stages of design imposes constraints on the diversity of tower morphology, the timeliness of performance evaluation, and the efficient integration of systems. Therefore, targeting the geometric characteristics of high-rise office towers, a systematically developed and universally applicable design grammar, named “Vertex-Based Polygonal Generative Grammar (VPGG)” is proposed. Additionally, a corresponding early-stage performance driven High-rise Office Tower Generative Design Framework (HOT_GDF) is introduced. Case study results demonstrate that, with the support of Artificial Neural Network, utilizing this system can not only globally explore the diversity of tower morphologies but also efficiently uncover greater energy-saving potential in complex architectural forms compared to simpler cubic forms, with an improvement of up to 7.76% during the early stages of design. Designed from the perspective of architects, the framework achieves logical, refined, and visual real-time interaction between computers and human minds during the early stages of tower design. This enhances design efficiency and facilitates design decision-making. It systematically integrates considerations for environmental performance, such as thermal load and thermal comfort, into the design process. Furthermore, it couples various aspects of morphological design with corresponding building performance, helping users in making design decisions from a rational and quantifiable perspective. This captures greater design potential, encompassing both form and performance, for high-rise office towers during the initial design phase.

The eco-environment-oriented development (EOD) mode is an innovative project organization and implementation approach that integrates ecological governance, industrial operations, and regional development. However, this mode still requires more in-depth research to strengthen its applicability to spatial perspectives and rural patterns. This study contributes to this context by proposing a rural spatial governance framework based on the EOD mode, focusing on the three main governance elements: space, capital, and subject. By constructing a conceptual model of the multidimensional governance effectiveness of EOD systems, it reveals the coupling mechanisms of three rural elements and proposes governance modes with spatially integrated optimization, capital value circulation, and rural subject connection as the focus of elemental regulation. This mode is further demonstrated through instantiation. In response to the developmental dilemmas of the villages’ overall decline owing to coal mining subsidence on the Weibei Plateau, an integrated transformation plan for production, living, and ecological spaces is formulated, based on which the stage-specific focuses are clarified in the holistic governance path of “space-capital-subject”. The research findings exemplify the application value and feasibility in regulating element relationships and balancing multiple benefits and can provide a reference at the spatial level to promote rural sustainable development through ecological governance.

This study explores a new public space performance measure by integrating public space and walking research to examine the relationship between pedestrian traffic volume and social activity intensity in parks and plazas. Introducing the entry-exit correlation coefficient (EEC), the study utilized bootstrap resampling methods to analyze data and compare to 59 manual observations. Findings reveal a statistically significant negative relationship between EEC and social activities, with a coefficient of −0.2. Lower EEC values, indicating closer correlation between entry and exit, were associated with increased social activities in Dilworth Park. The high synchronization observed between EEC and social activities underscores the potential of EEC as a complementary tool to manual observation in public space research. Additionally, the study emphasizes the importance of considering thermal comfort in monitoring public spaces using EEC. While the study focused on a single case study, its results lay the groundwork for future research to apply automated pedestrian counting and EEC as performance measurements for public spaces.

This study investigates the air movement preference of males and females after moderate-intensity exercise. 35 participants dressed in 0.6 clo exercised for 15 min in a room at 30 °C and then entered another room at 24 °C/26 °C/28 °C. During the experiment, participants were able to adjust the fan speed according to their own thermal comfort needs. The results indicate that after a change in metabolic rate, female prefer higher fan usage and greater air movement compared to males. When the body returns to thermal comfort, male have higher fan usage and prefer higher air movement than female. There were no difference in subjective evaluation and skin temperature between female and male. However, the skin evaporative heat loss of female was significantly lower than that of male. The correlation between air temperature, air speed and the time after entering the room tailored to the thermal requirements of distinct genders following moderate-intensity exercise has been established, which can provide a comprehensive control strategy for achieving both comfortable and energy-efficient thermal environments.

Science and technology innovation has become the core driving force of urban development, and innovation spaces as the carriers of innovation activities have evolved continuously, forming the emerging model of innovation districts in recent years. However, the evaluation standard of innovation spaces has not changed with the evolution of the model, and the evaluation method that focuses on economic benefits still dominates the mainstream. As a result, the construction of innovation spaces around these indicators and guidelines lags behind the advanced level.

In this paper, we have systematically sorted out the relevant research progress of innovation districts, established a set of cases with global typicality, combined the dual attributes of “innovation characteristics + urban characteristics,” constructed a research framework for the spatial quality of innovation districts based on the dual perspectives of “innovation space,” and summarized the spatial quality evaluation model through analysis. We do an empirical study on Haidian District to find out how well innovation districts work in terms of space, find typical clusters, and come up with the most important aspects of their space quality. In order to observe the applicability of this method, it is also applied to the urban health check-up in Chaoyang District, Beijing. Through the expert seminar, the evaluation and analysis method of spatial quality of innovative urban areas is further verified and discussed. The results show that the integration of innovative urban areas and urban structures, and the collaborative development of innovative industries and high-quality spaces are the keys to promote the common development of innovative economy and cities. The new evaluation method can effectively measure the quality of innovation spaces, and has certain transferability.

科技创新已成为城市发展的核心驱动力，作为创新活动载体的众创空间也在不断发展，形成了近年来新兴的创新街区模式。然而，创新空间的评价标准并没有随着模式的演变而改变，以经济效益为核心的评价方法仍然占据主流。本文系统梳理了创新街区的相关研究进展，建立了一套具有全球典型性的案例，结合 "创新特征+城市特征 "的双重属性，构建了基于 "创新空间 "双重视角的创新街区空间品质研究框架，并通过分析总结出空间品质评价模型。我们对海淀区进行了实证研究，以了解创新区在空间方面的运行状况，发现典型集群，并总结出其空间质量最重要的方面。为了观察该方法的适用性，还将其应用于北京市朝阳区的城市健康体检。通过专家研讨会，进一步验证和讨论了创新城区空间质量的评价和分析方法。结果表明，创新型城区与城市结构的融合、创新型产业与高品质空间的协同发展是促进创新型经济与城市共同发展的关键。新的评价方法能有效衡量创新空间的质量，具有一定的可推广性。

GPS positioning data are increasingly utilized in environmental behavior studies to explore the spatial-temporal behavioral patterns of individuals. However, individuals' stay behavioral pattern and its influencing factors, which are particularly significant for the design and management of scenic architectural complexes, have not been thoroughly examined. Using GPS trajectory data collected from the Palace Museum in Beijing (China), this paper investigated the visitors' stay behavior patterns associated with temporal, spatial, and environmental influencing factors. Types of stay behavior and characteristics of stay in main stay areas were automatically recognized using Python algorithms for further and quantitative analysis. Results showed that visitors' stay time exhibited a consistent pattern regarding psychological time allocation, a relatively unsignificant pattern regarding lunch hour, and no clear pattern regarding fatigue feature. Grouped regression analysis showed positive linear relationships with similar slopes between the average stay length and the number of stay occurrences in each type of stay area. Partial correlation analysis revealed the underlying connection between the impact of seats and greenery on stay behavior. Individually, each of the two environmental elements showed limited effect on stay frequency and stay length, while incorporating greenery into seating areas would notably increase both stay frequency and stay length.

在环境行为研究中，越来越多地利用 GPS 定位数据来探索个体的时空行为模式。然而，对于对风景建筑群的设计和管理尤为重要的个体逗留行为模式及其影响因素，还没有进行深入研究。本文利用从中国北京故宫博物院收集到的 GPS 轨迹数据，研究了与时间、空间和环境影响因素相关的游客逗留行为模式。利用 Python 算法自动识别了主要逗留区域的逗留行为类型和特征，并进行了进一步的定量分析。结果表明，游客的逗留时间在心理时间分配上表现出一致的模式，在午餐时间上表现出相对不明显的模式，而在疲劳特征上则没有明显的模式。分组回归分析表明，平均逗留时间与各类逗留区域的逗留次数呈正线性关系，且斜率相似。局部相关分析表明了座椅和绿化对停留行为的影响之间的内在联系。单独来看，这两个环境要素对逗留次数和逗留时间的影响都很有限，而在座位区加入绿化则会显著增加逗留次数和逗留时间。

Location-based social media data provides a new perspective for understanding the relationship between human behavior and urban environments. However, further research is needed to determine the application of cognitive computing in urban environments and physical activities. This study proposes a cognitive computing framework for urban environments and human activities that extracts knowledge from structured and unstructured data through natural language processing and computer vision techniques. This paper utilizes a Naive Bayes Model constructed based on random reviews, as well as semantic segmentation and instant segmentation algorithms based on convolutional neural networks to obtain information about urban environments and human behavior from social media data and other geospatial resources. This study examines the relationship between the urban environment and residents' activity, including spatiotemporal behavior, public sentiment, and physical activity. The study found statistically significant results in subgroup analyses regarding the effects of urban environments on sentiment and physical activity, which also exhibited a strong social gradient consistent with traditional findings. This study validates the feasibility of using cognitive computing based on social media data to explore environmental behaviors, providing technical support for updating health promotion policies.

基于位置的社交媒体数据为理解人类行为与城市环境之间的关系提供了一个新的视角。然而，要确定认知计算在城市环境和物理活动中的应用，还需要进一步的研究。本研究为城市环境和人类活动提出了一个认知计算框架，通过自然语言处理和计算机视觉技术从结构化和非结构化数据中提取知识。本文利用基于随机评论构建的 Naive Bayes 模型，以及基于卷积神经网络的语义分割和即时分割算法，从社交媒体数据和其他地理空间资源中获取有关城市环境和人类行为的信息。本研究探讨了城市环境与居民活动之间的关系，包括时空行为、公众情绪和身体活动。研究在分组分析中发现，城市环境对情绪和体育锻炼的影响具有显著的统计学意义，同时还表现出强烈的社会梯度，这与传统的研究结果一致。这项研究验证了基于社交媒体数据使用认知计算探索环境行为的可行性，为更新健康促进政策提供了技术支持。

The purpose of this research is to explore how the design of buildings and spaces affects our comfort. The study examines how our visual surroundings and emotional responses are connected. The hypothesis is that people's emotions are influenced by what they see in the buildings, spaces, and furniture around them. Each personality type may have a unique emotional response to their surroundings. The study has three main goals: to analyze the built environment, to assess psychological well-being, and to conduct neuroscience analysis. The built environment analysis is divided into two groups: architecture design analysis and street view design analysis. The psychological well-being analysis identifies three key factors. The neuroscience analysis shows that rectangular shapes combined with linear ornamentation and calming colors create the most comforting building design. The most comfortable street view includes an abundance of greenery with sun-shading effects. In conclusion, the study confirms that architecture affects our emotions. The factors that contribute to our comfort are stored in our mind and body over time. Our mood and emotional state are influenced by what we see in our surroundings. The questionnaire and experiment results support these conclusions.

这项研究的目的是探索建筑和空间设计如何影响我们的舒适度。本研究探讨了视觉环境与情绪反应之间的联系。我们的假设是，人们的情绪会受到他们所看到的周围建筑、空间和家具的影响。每种性格类型的人都可能对周围环境产生独特的情绪反应。这项研究有三个主要目标：分析建筑环境、评估心理健康和进行神经科学分析。建筑环境分析分为两组：建筑设计分析和街景设计分析。心理健康分析确定了三个关键因素。神经科学分析表明，矩形形状与线性装饰和平静的色彩相结合，创造出最舒适的建筑设计。最舒适的街道景观包括大量具有遮阳效果的绿色植物。总之，这项研究证实，建筑会影响我们的情绪。促使我们感到舒适的因素会长期储存在我们的身心中。我们的情绪和情感状态会受到周围环境的影响。问卷调查和实验结果都支持这些结论。

Internal migration motivated by access to higher education is a relatively unexplored topic in Colombia, leading to a lack of data on its dimensions, characteristics, and impacts on urban space and the emotional conditions of migrants. For this reason, an academic program of architecture in a public university was selected to comprehend the internal migrations of students, exploring their territorial experiences, living conditions, and social mobility capacity. An exploratory methodology was designed to recognize the phenomenon through a descriptive analysis, utilizing institutional data, surveys, and interviews. The research identifies the primary reasons, barriers, and impacts experienced by the migrant population in Ibagué, Colombia. The study concludes with recommendations pertaining to both institutional and urban planning to address these identified challenges.

在哥伦比亚，以接受高等教育为动机的内部移民是一个相对未被探讨的话题，导致缺乏有关其规模、特点、对城市空间的影响以及移民情感状况的数据。因此，我们选择了一所公立大学的建筑学专业来了解学生的内部迁移情况，探索他们的地域经验、生活条件和社会流动能力。研究设计了一种探索性方法，通过描述性分析，利用机构数据、调查和访谈来认识这一现象。研究确定了哥伦比亚伊瓦格移民人口经历的主要原因、障碍和影响。研究最后提出了与机构和城市规划相关的建议，以应对这些已确定的挑战。
