摘要

绿色屋顶对城市可持续发展的贡献日益得到认可，其好处包括热调节、雨水管理、能源效率、改善空气质量和提高生物多样性。然而，在地中海气候条件下，绿色屋顶的性能仍未得到充分探索。本研究评估了三种不同的绿色屋顶技术--实验型、排水模块型和绿色安全型--在地中海气候条件下的效果，重点关注热调节、保水和节能。在为期八天的夏季期间，部署了高精度仪器，包括热电偶、热通量传感器和时域反射仪（TDR）探头，以监测其性能。实验技术将生物炭融入基质，实现了最佳热性能，与参考屋顶相比，表面温度最高降低了 9.8 °C，平均每天节省制冷能源 3.8 千瓦时，模拟期间总共节省能源 10%。排水模块技术表现一般，表面温度降低了 6.5 °C，总节能率为 6.5%，相当于每天节省 2.5 千瓦时的制冷能源。相比之下，绿色安全技术的表面温度最高，保水性最低，表面温度降低了 5 °C，能源节约率仅为 5%（相当于每天节约 1.9 千瓦时的能源）。这些发现强调了生物炭强化基质在缓解城市热岛效应、减少制冷能源需求和提高建筑能效方面的潜力。这项研究为城市规划者、建筑师和政策制定者提供了定量见解，帮助他们在气候条件具有挑战性的地区实施更有效、更可持续的绿色屋顶设计，从而支持城市恢复能力和气候适应能力。

Innovative green roof technologies in Mediterranean climate: Implications for sustainable design of the built environment

Green roofs are increasingly recognized for their contributions to urban sustainability, offering benefits such as thermal regulation, stormwater management, energy efficiency, improved air quality, and enhanced biodiversity. However, the performance of green roofs in Mediterranean climates remains underexplored. This study evaluates the effectiveness of three distinct green roof technologies—Experimental, Draining Modules, and Green Safe—in Mediterranean conditions, focusing on thermal regulation, water retention, and energy savings. High-precision instruments, including thermocouples, heat flux sensors, and Time Domain Reflectometry (TDR) probes, were deployed to monitor performance over an eight-day summer period. The Experimental Technology, integrating biochar into the substrate, achieved the best thermal performance, with a surface temperature reduction of up to 9.8 °C compared to the reference roof, an average daily cooling energy savings of 3.8 kWh, and a total energy savings of 10 % over the simulation period. The Draining Modules Technology demonstrated moderate performance, with a surface temperature reduction of 6.5 °C and a total energy savings of 6.5 %, equating to 2.5 kWh of daily cooling energy savings. In contrast, the Green Safe Technology exhibited the highest surface temperatures and the lowest water retention, resulting in a surface temperature reduction of 5 °C and energy savings of only 5 % (equivalent to 1.9 kWh of daily energy savings). These findings underscore the potential of biochar-enhanced substrates in mitigating the Urban Heat Island (UHI) effect, reducing cooling energy demand, and improving building energy efficiency. This research provides quantitative insights for urban planners, architects, and policymakers seeking to implement more effective and sustainable green roof designs in regions with challenging climatic conditions, thereby supporting urban resilience and climate adaptation.
