“…Numerous studies have extensively investigated the possibilities of health promotion in natural environments and urban public spaces [48][49][50]. However, most of the studies on sky gardens focus on only one or two dimensions [8,17,18,66] and lack a comprehensive framework to integrate people's multidimensional perceptions to assess the difference between the supply of and the demand for the health promotion qualities of sky gardens.…”

“…The first two types of sky garden mainly cater to static leisure activities, while move-pass sky gardens primarily support dynamic viewing activities. Their spatial form is predominantly linear [66], and they also serve a transportation function. The public's attention to its health promotion and its performance are both low.…”

The quality of landscape space directly influences public health behaviors, making public assessments of the qualities of the sky garden landscape crucial for optimizing it. This article focuses on three types of typical high-rise building sky garden (plaza-park, rest-stay, and move-pass type) and establishes an evaluation framework for their health promotion characteristics (24 indicators in 7 dimensions) based on existing restorative environment research. Then, questionnaires (354 valid responses) and quantitative calculations were employed to assess the public’s perception of demand in health behaviors and the spatial supply of different sky garden types. Ultimately, the data were processed to propose targeted interventions and recommendations to enhance health benefits using the comprehensive importance-performance analysis method. The results show the following: (1) The public seems to have widely accepted sky gardens in the context of high-density urban environments (near 6.92, below the mean of 7.09). They place greater emphasis on spatial indicators that cater to relaxation activities and show heightened sensitivity toward public facilities (7.32–8.00) that contribute to physical and mental health-related activities. (2) The health promotion performance of different types of sky garden shows significant variation, with the rest-stay sky gardens at the embodied scale demonstrating the greatest competitive advantage. (3) The development of sky gardens has significant potential, and different types of sky garden need to specifically lever-age their characteristics as complementary public spaces.

To respond the expansion of urban centers, the proliferation of high-rise buildings demands a better understanding of the aerodynamic phenomena around skyway bridges connecting these structures. This analysis, utilizing the advanced computational fluid dynamics verified by wind tunnel test data, investigates the wind characteristics around such bridges, crucial for structural stability, pedestrian comfort, and aerodynamic efficiency. This study focuses on the interactions between a 2 × 2 building array with a building height-to-street width ratio of 30 and a skyway bridge, investigating those factors such as bridge influence, building structures, building height, and bridge position. Using the three-dimensional steady Reynolds-averaged Navier–Stokes equations along with the Reynolds stress model for turbulence closure, the results show that the presence of skyway bridge significantly modifies local wind patterns. Wind speed and turbulence intensity are impacted differently based on the bridge's upstream or downstream settings. Downstream bridges tend to reduce wind speeds due to the sheltering effects, while upstream placement of bridge can enhance wind flow, affecting both the structural design and pedestrian comfort. Additionally, building height variations adjacent to the bridge influence wind velocity and pressure profiles, with taller buildings intensifying wind speeds at lower levels because of the channeling effects. These insights are pivotal for optimizing the skyway bridge designs to improve airflow distribution, enhance environmental sustainability, and ease wind-caused disturbances, offering a guideline for future architectural and urban planning in high-rise districts.
