Abstract This study explored subjective responses towards various environmental quality parameters. In order to investigate the combined effects of sound, light, and heat on overall comfort (evaluated by vote, OCV) pedestrians, two residential areas in Yubei District, Chongqing (a Cfa city China) were selected for field measurements combining questionnaires. Three main conclusions drawn. Firstly, average outdoor neutral temperature (NT), LAeq, LUX 26.6 °C (indicated physiologically equivalent temperature, PET), 56.5 dBA, 21.4103 lx, respectively. Secondly, since both physiology psychology, thermal perceptions varied acoustic light environments. could be explained different NTs sound pressure or levels. Thirdly, factors had significant comfort. Significant positive correlation between stress (PET) OCV was found (sig＜0.000); while intensity not always significant. Hence, played a role people’s Findings this directive future environment design creating more comfortable spaces.

As an important part of urban ecosystems, trees can effectively alleviate the heat island effect. Tree canopies cool and humidify through shading evapotranspiration, regulating thermal environment. So far, many studies have analyzed mitigation effect green spaces; however, there are relatively few on cooling tree canopies. Specifically, relevant research focusing different spatial scales has not been explored. Therefore, this review systematically summarizes benefits canopy carried out in recent years, analyzes content, evaluates indicators key influencing factors from four scales: urban, block, community, individual. It was found that factors, other vegetation environmental jointly affect cooling. This focuses at scales. The smaller scale, more discussion attention will be paid to factors. paper puts forward major directions for future development, providing optimization strategies planning or plant design context climate change.

Thermal comfort studies are usually employed to find subjective thermal responses [indicated by neutral temperature (NT), i.e. the with no stress] of residents from a region towards environments. According recently published works in literature, NTs affected many factors, such as geographical location and microenvironments. To elucidate origins these effects, impact microenvironment elements around water surface on pedestrians' perceptions was systematically investigated this work. The Fujiang River (FJR) Mianyang City taken sample site. municipal meteorology station is located next site 2.5 km. By performing measurements combining questionnaires, it found that riverside NT (indicated physiologically equivalent temperature, PET) summer 2023 21.4 °C. relationship between distance (DFW) quadratic linear. same phenomenon took place using either PET or Universal Climate Index (UTCI) indexes. Meanwhile, meteorological contexts also NTs, including relative humidity (RH) air velocity (Va). Regarding RH, NPET increased 15.2 °C (RH = 50%) 26.9 90%). In contrast, dropped 23.0 - 50.6 when Va 0.2 m/s, respectively. From our analysis, demonstrated human significantly both microenvironmental backgrounds surface. Our work provides valuable insights for proper use surfaces urban design adjusting comfort.

Poor thermal and light climates can have significant negative effects on human living qualities. Exploring sustainable ways to address these issues is an urgent task, at the street level, trees pose a potential solution. This study aimed determine effect of pedestrians' physiological comfort under different conditions. was accomplished by field surveys, including questionnaires distributed several forested streets in Qingbaijiang District (QBD), suburban area Chengdu, China. Data analysis showed that people had responses towards either physical or meteorological factors. They responded differently various environmental factors, varied over contexts. It found neutral temperature lighting levels were 28.64 °C, as indicated physiologically equivalent (PET, °C), 0.91 klx, illumination (klx). The percentage favor larger tree crowns increased considerably for PET (from 60 % 30 °C 90 45 °C) 0 klx 100 20 klx) elevations small-sized trees.

In relative terms, crown sizes (diameter, TCD) influence comfort. Increasing TCD 1 m resulted reduction 0.449 and/or 0.475 (sig. < 0.001).

Ribbon waterfront parks in hot summer and cold winter regions play a crucial role microclimate regulation thermal comfort enhancement due to the combined effects of water bodies vegetation. This study focuses on ribbon Hefei. investigates influence park environmental factors (e.g., plant community characteristics, spatial configuration bodies, plaza layouts) environment through field measurements ENVI-met numerical simulations. Based studies literature review, five were selected as test variables: body direction (S), tree planting density arrangement (A), square distribution form (B), location (C), pavement material (D). Using orthogonal testing, 64 different scenarios under four distinct orientations designed simulated using (Version 5.6.1), followed by quantitative analysis simulation results. The findings reveal that interaction between orientation prevailing wind significantly influences cooling efficiency both upwind downwind regions. In addition, Range Analysis (RA), variance (ANOVA), order magnitude effect each experimental factor Universal Thermal Climate Index (UTCI) can be derived: (A) > (D) (C) forms squares (B). Finally, this suggests various factor-setting schemes for are tailored microclimatic requirements. It also provides design recommendations improve based bodies. Furthermore, it offers specific references foundations planning, designing, optimising, renovating similar scales.
