Various physical characteristics of urban impervious surfaces (ISAs) and green spaces (UGSs) collectively regulate environmental temperatures through heating cooling processes. However, current research often analyzes each regulating factor as an independent variable when examining its relationship with land surface temperature (LST), limited studies considering the combined contribution weights all factors. Based on multi-source remote sensing data ground observations from near summers 2014, 2016, 2017, 2018 in built-up area Xuzhou City, numerical values spatial distributions 15 factors, including ISA density (fi), albedo (Albedo), population (Population), anthropogenic heat flux (AHF), maximum patch index (LPIISA), natural connectivity patches (COHESIONISA), aggregation (AIISA), average shape (SHAPE_MNISA), UGS (fv), evapotranspiration (ET), shading (UGSSI), (LPIUGS), (COHESIONUGS), (AIUGS), (SHAPE_MNUGS), were separately extracted within study area. Using geographically weighted regression models bivariate autocorrelation models, we obtained quantitative correlations between factors LST. The results revealed that selected exhibited high goodness-of-fit significant LST, which led to their categorization into eight warming seven detection Geographic Detector further reveals indicate have higher explanatory power for LST compared UGSSI contributing most while Population contributed least. Furthermore, interaction highlighted variations different combinations Ultimately, it has identified proven be effective mitigating environment across three scenarios: alone, a combination both suggested are follows: fi ∩ Albedo, LPIISA, fv, LPIUGS, UGSSI, Albedo UGSSI. Therefore, our findings hold potential provide valuable reference planning climate governance. Tailoring local context selecting ones can enable cost-effective mitigation environment.

Radiative cooling textiles hold promise for achieving personal thermal comfort under increasing global temperature. However, urban areas have heat island effects that largely diminish the effectiveness of as wearable fabrics because they absorb emitted radiation from ground and nearby buildings. We developed a mid-infrared spectrally selective hierarchical fabric (SSHF) with emissivity greatly dominant in atmospheric transmission window through molecular design, minimizing net gain surroundings. The SSHF features high solar spectrum reflectivity 0.97 owing to strong Mie scattering nano-micro hybrid fibrous structure. is 2.3°C cooler than solar-reflecting broadband emitter when placed vertically simulated outdoor scenarios during day also has excellent properties.

The process of urbanization exacerbates the urban heat island phenomenon. In order to reasonably identify functional zones, and reveal influence buildings on land surface temperature (LST). Guiyang, a multi-mountainous city in China, was taken as research area, Open Street Map (OSM) use type data were used zones. Subsequently, correlation between building morphology metrics LST analyzed using Pearson boosted regression tree (BRT) model. results showed that: (1) There significant differences among different (2) relative contribution value density (BD) high, it significantly exacerbated effect across all with maximum impact reaching 2.5°C Utility zone. (3) Mean height (MBH), Southerly wind speed (S_Wind speed) Landscape shape index (LSI_Building) had alleviating thermal environment, mitigation degree highest Residential zone Ecological zone, 0.6°C, 0.8°C 2.0°C, respectively. This study enhances our understanding relationship functions LST, providing valuable insights for mitigating environment promoting sustainable development.

Heat is added to the surroundings as a result of replacing natural landscapes with buildings. This includes waste heat from air conditioning systems and transferred into environment exterior surfaces. Here, we propose new concept "negative sensible release" buildings—that is, buildings that put less than released unbuilt terrain upon which building was constructed. We explore potential for net negative releasing through simulation studies in hot arid humid cities—Phoenix, Houston. Results show it possible achieve release low-rise office by simply increasing roof wall solar reflectance using existing technologies. While typical 2-story can generate average fluxes around 100 W/m2 (based on footprint area), 0.2 0.9 walls 0.65, same heating 20 40 W/m2. Increasing insulation energy efficiency appliances equipment further reduce points compelling mechanism whereby be designed or retrofitted have beneficial impact local thermal environment.
