The history of imperial dynasties in West Asia is replete with examples of remarkable urban foundations. Two notable instances are the Sasanian Ardašīr-xwarrah and the Abbasid Madīnat al-Salām, which can be classified as cosmic cities or heterotopias. This article examines the utopian foundations of these heterotopias. To this end, it analyzes four religious and imperial spaces: the representation of the earth and sky in the Zoroastrian cosmography, Yima’s Vara according to the Avestan texts, Ardašīr-xwarrah, and finally, Madīnat al-Salām. This investigation aims to ascertain the extent to which the spatial characteristics of each of these spaces have been utilized in the production of the subsequent architectural forms. Similarly, it examines the development of the cosmological and eschatological paradise in relation to the Achaemenian and Sasanian royal gardens. The theoretical framework of this study is based on Michael Foucault’s notion of heterotopia, which has been further developed by Henri Lefebvre’s theory of space. The conceptual metaphor theory offers a cognitive linguistic foundation for elucidating the projections of utopias and heterotopias onto one another. To this end, the article focuses on the conceptual metaphor GOD IS A KING. Full article

Drone-based imaging polarimetry is a valuable new tool for the remote sensing of the polarization characteristics of the Earth’s surface. After briefly reviewing two earlier drone-polarimetric studies, we present here the results of our drone-polarimetric campaigns, in which we measured the reflection–polarization patterns of greenhouses. From the measured patterns of the degree and angle of linear polarization of reflected light, we calculated the measure (plp) of polarized light pollution of glass surfaces. The knowledge of polarized light pollution is important for aquatic insect ecology, since polarotactic aquatic insects are the endangered victims of artificial horizontally polarized light sources. We found that the so-called Palm House of a botanical garden has only a low polarized light pollution, 3.6% ≤ plp ≤ 13.7%, while the greenhouses with tilted roofs are strongly polarized-light-polluting, with 24.8% ≤ plp ≤ 40.4%. Similarly, other tilted-roofed greenhouses contain very high polarized light pollution, plp ≤ 76.7%. Under overcast skies, the polarization patterns and plp values of greenhouses practically only depend on the direction of view relative to the glass surfaces, as the rotationally invariant diffuse cloud light is the only light source. However, under cloudless skies, the polarization patterns of glass surfaces significantly depend on the azimuth direction of view and its angle relative to the solar meridian because, in this case, sunlight is the dominant light source, rather than the sky. In the case of a given direction of view, those glass surfaces are the strongest polarized-light-polluting, from which sunlight and/or skylight is reflected at or near Brewster’s angle in a nearly vertical plane, i.e., with directions of polarization close to horizontal. Therefore, the plp value is usually greatest when the sun shines directly or from behind. The plp value of greenhouses is always the smallest in the green spectral range due to the green plants under the glass. Full article

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. Full article

Although an increase in walking is recommended to improve physical activity and public health, especially among older adults, the frequency of outdoor pedestrian activities, including walking, should be reduced when there is increased air pollution. There is limited understanding of the inter-relationships between two research fields, namely, older adults walking behavior and air pollution. This study investigates these factors and identifies their relationships with associated built environment factors. More than 200 peer-reviewed journal articles that met the selection criteria were analyzed. The factors pertaining to air pollution in the built environment were classified based on the scale of the urban environment. Comparing the built environment factors related to both fields of study, several common features such as the type of street enclosure (urban spatial), sky view factor (urban spatial), percentage of front gardens (urban design), and land use patterns were identified. Furthermore, we found that it is important to understand how the subjective/objective measures of the urban-design-related factors identified on the street are linked to air pollution at both street and neighborhood scales. A wide range of urban vegetation factors (pattern, size, and density) in both fields of study at a street scale were also identified. These inter-relationships need to be examined by future studies to get a clearer picture of the factors which might improve walking behavior among older adults while reducing the air pollution in urban environments.

Virtual reality (VR) technology has the potential to revolutionize public engagement in the design of urban projects, leading to more sustainable and inclusive environments. This research scrutinizes this potential through a study of elevated urban spaces, specifically the Sky Garden and Crossrail Place in London. Comparing real and virtual interactions, the aim is to highlight their differences and similarities while underscoring the importance of design decision-making for sustainable public places. Through walk-along interviews with 33 visitors in each space and a VR experiment with a separate group of 33 participants, the study analyses the effectiveness of VR as a co-design tool. The outcomes demonstrate that VR positively influences user involvement and allows for the production and real-time testing of design alternatives. Significantly, the majority of participants, who had not physically visited the spaces, could identify design concerns and propose potential activities and features through the VR experiment. These findings were consistent with those expressed by actual users of the spaces. By comparing human activities, circulation, and design concerns in both physical and virtual environments, the research underscores the potential and limitations of VR as a co-design tool for creating sustainable public spaces.

Purpose: This paper investigates the potential of virtual reality (VR) technologies—specifically, building information modeling (BIM) (“Autodesk Revit”) and game engines (“Unreal Engine”)—to enhance public involvement in the design and execution of architecture and urban projects. The main research question focuses on comparing the effectiveness of these two methods in creating an interactive design model for participatory design in public spaces. Methods: The study employed a VR exploratory experiment with 33 participants, followed by semi-structured interviews to analyze two recent developments in London: the Sky Garden, and Crossrail Place Roof Garden. Participants interacted with the design models and provided feedback on their experiences. Results: The findings demonstrate that integrating VR with BIM software using the Enscape plugin effectively enhances user involvement, enabling real-time generation and testing of design alternatives. While both methods were found to be beneficial, participants reported a preference for the direct implementation of VR in BIM software. Conclusions: This research highlights the potential of VR technologies—specifically, BIM and game engines—as a co-design approach for public and social spaces in urban environments. It also identifies limitations and future research opportunities in adopting these methods for participatory design. Full article

The purpose of this study was to investigate the physiological recovery effects of olfactory, visual and olfactory–visual stimuli associated with garden plants. In a randomized controlled study design, ninety-five Chinese university students were randomly selected to be exposed to stimulus materials, namely the odor of Osmanthus fragrans and a corresponding panoramic image of a landscape featuring the plant. Physiological indexes were measured by the VISHEEW multiparameter biofeedback instrument and a NeuroSky EEG tester in a virtual simulation laboratory. The results showed the following: (1) In the olfactory stimulation group, from before to during exposure to the stimuli, the subjects’ diastolic blood pressure (DBP) (ΔDBP = 4.37 ± 1.69 mmHg, p < 0.05) and pulse pressure (PP) values increased (ΔPP = −4.56 ± 1.24 mmHg, p < 0.05), while their pulse (p) values decreased (ΔP = −2.34 ± 1.16 bmp, p < 0.05) significantly. When compared to the control group, only the amplitudes of α and β brainwaves increased significantly (Δα = 0.37 ± 2.09 µV, Δβ = 0.34 ± 1.01 µV, p < 0.05). (2) In the visual stimulation group, the amplitudes of skin conductance (SC) (ΔSC = 0.19 ± 0.01 µΩ, p < 0.05), α brainwaves (Δα = 6.2 ± 2.26 µV, p < 0.05) and β brainwaves (Δβ = 5.51 ± 1.7 µV, p < 0.05) all increased significantly relative to the control group. (3) In the olfactory–visual stimulus group, DBP (ΔDBP = 3.26 ± 0.45 mmHg, p < 0.05) values increased, and PP values decreased (ΔPP = −3.48 ± 0.33 bmp, p < 0.05) significantly from before to during exposure to the stimuli. The amplitudes of SC (ΔSC = 0.45 ± 0.34 µΩ, p < 0.05), α brainwaves (Δα = 2.28 ± 1.74 µV, p < 0.05) and β brainwaves (Δβ = 1.4 ± 0.52 µV, p < 0.05) all increased significantly relative to the control group. The results of this study show that the interaction of olfactory and visual stimuli associated with a garden plant odor landscape was able to relax and refresh the body to a certain extent, and this physiological health effect was greater with regards to the integrated response of the autonomic nervous system and central nervous system than the effect of only smelling or viewing the stimuli. In the planning and designing of plant smellscapes in garden green space, it should be ensured that plant odors and corresponding landscapes are present at the same time in order to ensure the best health effect.

This paper addresses a challenging global problem, insufficient accessible urban public green space, based on building typology. Offering sufficient public green spaces and maintaining the equalities of citizens’ accessibility in high-intensity urban cities has been increasingly challenging. Thus, providing adequate and accessible green public spaces by 2030 is a sub-goal of SDGs No. 11. Solving this urban problem is commonly considered the responsibility of urban planning; however, the potential of buildings is scarcely discussed in academia. Luckily, in the industry, many top architecture firms (studios) have tapped the particular potential of buildings via design practice. This practice-led research aims to understand the efforts made by industrial circles. Based on the fieldwork worldwide, this study proposes a ‘spiral space’ building typology to work as a conceptual framework for this emerging field. The key benefit of this building typology—incremental production of public green spaces—is qualitatively verified, and the good flexibility and international acceptance of this building typology are demonstrated based on global cases. This work could serve as a basis for future research on how buildings could play a greater role in supporting urban sustainability, such as enhancing the residents’ accessibility to public green space in metropolises. In addition, the building typology and corresponding design strategies discussed herein could also serve as references for future design practice for architects. Full article

This paper studies the spatial characteristics of sky gardens as public spaces to explore their potential to support urban sustainability in dense cities. This research understands public spaces as spaces that are open and available in different levels of access and use. The research focuses on 982 sky gardens in Shenzhen, Hong Kong, and Singapore. It adopts a mixed methodology, including site visits and observations, statistic measurements (based on SPSS software), and Grey Relation Analysis (GRA) methods. The research follows three steps: first, it studies the urban context, including urban density, land uses, and policy regulations regarding sky gardens and sustainability. Second, it examines sky gardens’ spatial characteristics in terms of form (morphology, typology, size, affordances, configuration), openness quality (accessibility, ownership, permeability), and geometry (open space ratio, height of space-to-building, void-to-solid ratio, shape index). Third, the research compares the findings in three case cities and discusses their potential to support urban sustainability. The results suggest that despite the limitations of sky gardens, they may play, to different degrees, fundamental roles as open public spaces in high-density urban environments supporting cities’ sustainability. High-density environments offer more opportunities for the sustainable development of sky gardens, which creates a new spatial paradigm for compact vertical greenery in high-density cities.

For the cultural heritage gardens in the urban environment, modern high-rise buildings inevitably change their original landscape and form a new landscape experience with visual impact. Whether cultural heritage gardens and modern cities can coexist harmoniously is one of the critical issues to achieve their sustainable development. This research aimed to find an indicator of landscape morphology, which can predict the visitor’s cognition for such cultural landscape forms. This study surveyed tourists’ preferences in six selected cultural heritage gardens in Tokyo. We used hemispheric panoramas to calculate the view factors of certain elements of the landscape at the observation points. The results showed that Sky View Factor was a positive predictor of tourists’ preference, and this predictability did not change significantly with the attributes of tourists. We also found that tourists’ attitudes towards the high-rise buildings outside the gardens have become more tolerant and diverse. These findings could be applied to predict visitors’ perception preference of cultural heritage landscape in the context of urban renewal, contributing to the sustainable development of cultural heritage landscape and urbanization.

High-rise buildings are known to be highly energy intensive, adding stress on already stressed resources. Alternatively, designers are looking at passive strategies and investing in architectural elements, such as sky gardens, which could improve the performance of buildings. Sky gardens are green areas located in a building which are exposed to the outdoors. They could provide multifaceted improvements in buildings by introducing environmental benefits to occupants and altering microclimate. This study aims to determine the wind comfort and thermal condition in sky gardens in high-rise buildings using numerical modelling. Different geometrical configurations of sky gardens were simulated and analysed. Based on the initial results, the study reveals that sky gardens can generate high wind velocities of the order ~10 m/s when located on a high-rise building. The addition of features such as trees and other architectural elements, which can act as a buffer, can help attenuate the high wind speeds and creating habitable spaces. The reduction varies 50%–80%, depending on the location and spatial domain of the sky garden. Furthermore, the study also investigated the reduction in air temperature due to the addition of trees, which can further reduce temperature in hot weather. Full article
