“…Most previous studies on sustainable urban campuses have discussed the comprehensive achievement of SDGs (Longoria et al, 2021), green campus (Atici et al, 2019), the importance of building open green spaces (Olugu et al, 2019), and the role of open green space in reducing surrounding air temperature (Feng et al, 2021). Another study observed to be closely related to the focus of this research discusses the role of campus parks in optimizing students' concentration and reducing mental fatigue (Liprini & Coetzee, 2017).…”

“…Biophilic design is an approach formulated based on biophilia theory, with its focus on attempting to reconnect people to nature by improving their interaction with it (Arof et al, 2020;Makram & Ouf, 2019). In this approach, energy saving is achieved along with ehancement of people's mental health (Feng et al, 2021;Liprini & Coetzee, 2017). This method has become more popular among architects and building designers since the publication of 14 biophilic design patterns (Browning et al, 2014).…”

Universities are trying to make their campuses sustainable. One of the tools used to evaluate the level of campus sustainability is UI Green Metric World University Rank (UIGMWUR), which focuses on sustainable efforts implemented by universities. It has become clear, however, that it is difficult for urban campuses to obtain a good ranking under the UIGMWUR framework due to the limited amount of open green space in dense city areas. Therefore, one possible strategy involves optimizing the existing open green space. This research was conducted to determine some possible solutions through the use of observation and a Likert scale questionnaire. The initial result showed that the building coverage area exceeds the government standard, and that most of the people on campus have a negative perception of the open green space that currently exists. The community prefers green space that offers privacy, with big canopy trees and natural elements. The study combined these preferences with a biophilic design pattern to generate a design proposal. It was concluded that there is a need to optimize the open green space in urban campuses based on four strategies: building vertical gardens, renovating the existing open green spaces, optimizing the buildings, and constructing vertical parking facilities.

“…Based on multiple regression analysis, after LULC types were transformed into dummy variables, the results confirmed the dominant influence of green space (GS_in and GS_out) on the riverbank among the different LULC types on the UCI effect of the river reach (Supplementary Table 1 ). This is because vegetated areas are not only associated with a relatively lower air/surface temperature 39 – 41 , but can also cool their immediate surroundings 42 , 43 . Therefore, a dataset describing the characteristics of river reaches and adjacent GS was prepared.…”

Urban water bodies can effectively mitigate the urban heat island effect and thus enhance the climate resilience of urban areas. The cooling effect of different water bodies varies, however, the cooling heterogeneity of different sections of a single watercourse or river network is rarely considered. Based on various satellite images, geospatial approaches and statistical analyses, our study confirmed the cooling heterogeneity from spatial and seasonal perspectives of the Suzhou Outer-city River in detail in the urban area of Suzhou, China. The cooling effect of the river was observed in the daytime in four seasons, and it is strongest in summer, followed by spring and autumn, and weakest in winter. The combination of the width of the river reach, the width and the NDVI value of the adjacent green space can explain a significant part of the cooling heterogeneity of the different river sections in different seasons. Land surface temperature (LST) variations along the river are more related to the width of the river reach, but the variations of the cooling distance are more related to the adjacent green space. The cooling effect of a river reach could be enhanced if it is accompanied by green spaces. In addition, the cooling effect of a looping river is stronger on the inside area than on the outside. The methodology and results of this study could help orient scientific landscape strategies in urban planning for cooler cities.

“…Through field measurements and ENVI-met simulations, vegetation's impact on microclimate has been determined. The studies indicate that the vegetation canopy and leaf area index have a more significant effect on average radiant temperature and comfort compared to humid and hot climate regions, while also contributing to energy savings [11][12][13]. Water bodies, as important elements in the environment, contribute to heat absorption through evaporation.…”

To address the poor thermal comfort of library exteriors in hot and dry regions during the summer, this study takes the libraries of universities in Xinjiang as its research object. It corrects the range of the perceived environmental temperature (PET) index for evaluating comfort in Xinjiang by combining subjective and objective methods. It explores the impact and adjustment mechanism of physical parameters on PET through field measurements and simulations. Finally, it determines the optimal external environmental design based on PET. The research results show that the neutral temperature of PET in Xinjiang during the summer is 27.44 °C, and the optimal comfort temperature range is 25.52–29.36 °C. The correlation between meteorological and physical parameters and PET is as follows: Tg > G > Ta > RH > SVF > reflectance > Va. The optimal PET design includes a combination of a water body in the upwind direction on the south side, an asphalt underlay, grass, and large-leaved wax vegetation. In the optimal scheme, PET decreased by 6.73 °C, or 12.59%, compared with Case 0 at 18:00. This study provides a reference for the design of external environmental conditions in hot and dry regions during the summer.
