Previous research has demonstrated that the multiple environmental benefits of green roofs are primarily associated with their evaporative cooling effect. However, current studies on roof evapotranspiration (ET) mainly focus extensive roofs, and effect intensive is still unclear. Using AQUA City in Nanjing as a case study, this employs three-temperature (3T) model combined high-resolution thermal infrared imagery obtained via an unmanned aerial vehicle (UAV) to estimate ET different vegetation types. The study aims explore spatiotemporal variations surface temperature, rate, rate for various types under typical seasonal (summer winter) weather conditions (sunny, cloudy, rainy before after days). results showed that: (1) rates effects differed significantly, shrubs having fastest rates, followed by arbors, grasslands relatively low rates. (2) Solar radiation air temperature most crucial meteorological parameters inducing roofs. In performance patterns summer > winter sunny cloudy days. (3) spatial distribution tree irrigation plant groups, some low-temperature diffusion phenomena adjacent small microenvironments were evident, while smaller shows opposite warming characteristics. This offers valuable reference quantifying facilitating optimization configuration supporting sustainable urban development.

Green roofs are a fundamental technology in the transformation of urban centers into more sustainable environments, with positive impact on buildings, cities, and their inhabitants. Yet, green roof may require use materials high environmental impact, namely, when associated large transport distances. The present work arises from need to find an solution eco-school one Azores islands. It tests wooden structure using local materials. Prototypes were built monitor performance complement theoretical information investigated regarding construction systems alternative installation prototypes was accompanied by school community, monitored. pumice stone proved be efficient for drainage layer roof. soil (volcanic origin) instead commercial substrate properly, both vegetation growth. Finally, results also contribute better understanding structures encourage future projects, view towards circular economy.

Urban green spaces (UGS) play a critical role in mitigating the urban heat island (UHI) effect and addressing climate change challenges through their cooling effects. Expanding space optimizing its layout are key strategies planning. However, with limited land resources, maximizing efficiency becomes crucial. While previous studies have yet to reach consensus on optimal UGS size threshold for achieving maximum efficiency, this study employs high-resolution remote sensing imagery extract 25,594 patches Xi’an explores scale dependency of Results show that 54.20% exhibit “cooling effect”, reducing surface temperatures by 0.10 ± 0.13 °C 1.66 1.15 °C. A nonlinear relationship was observed between intensity size, influenced vegetation coverage edge complexity. Further analysis reveals medium-sized highest efficiency. These were categorized into five functional zones explore dominant factors affecting each zone, corresponding improvement proposed. findings provide insights refining thresholds.
