The worsening urban thermal environment has become a critical challenge in many cities. Trees, as vital components of green spaces, provide multiple ecosystem services, especially improving the microclimate. However, limited studies address how morphological changes during tree growth influence their cooling benefits. This study combined model with ENVI-met to simulate 27 scenarios subtropical square, considering three planting intervals, species, and stages evaluate daytime impacts. key findings include: (1) Tree size intervals are more important than quantity enhancing comfort. (2) Reducing by 2 m enhances effects but minimally affects PET (physiological equivalent temperature). (3) Increasing DBH (diameter at breast height) significantly improves cooling. For every 10 cm increase DBH, Michelia alba, Mangifera indica, Ficus microcarpa L. f. reduced solar radiation 19.54, 18.09, 34.50 W/m2, mean radiant temperature 0.61 °C, 0.68 1.35 respectively, while decreasing 0.23 0.46 °C. These empirical evidence practical recommendations for designing comfortable open spaces

Impact of Environmental Factors on Summer Thermal Comfort of Ribbon Waterfront Park in Hot Summer and Cold Winter Regions: A Case Study of Hefei

Sustainability, Journal Year: 2025, Volume and Issue: 17(7), P. 3026 - 3026

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.
