| 摘要: |
| 当前国际前沿的屋顶绿化研究表明，屋顶绿化的城市能源和城市生态环境等环境综合效能越来越受重视。结合屋顶绿化全生命周期分析，提出基于环境效能的“预研究、深化设计、效能评估”的屋顶绿化研究性设计，并将此设计方法应用于实际案例Joy Garden屋顶花园中，对其进行风环境和日照模拟，初步设计出3种方案，从安全性、环境效益和全生命周期的角度评价并确定最佳方案，在此基础上进行基于环境效能的深化设计项目建成后的效能评估结果表明，案例屋顶花园在建筑节能、雨洪管理、改善城市热环境、增加城市生物多样性等提高环境效能方面均起到一定的积极作用。 |

| Abstract: |
| The current international frontier researches on roof greening indicate that comprehensive environmental efficiency of urban greening and ecological environment of roof greening has attracted increasingly higher attention. With the whole life cycle analysis of green roofs, we put forward the research-oriented design of green roofs based on environmental efficiency “pre-study, deepening design and effectiveness evaluation”. We applied the design method to the practical case of Joy Garden to simulate its wind environment and sunshine. According to the simulation results, three schemes are preliminarily designed. We evaluated and determined the best scheme from the perspectives of safety, environmental benefit and whole life cycle, and further deepened the design based on the environmental efficiency. The effectiveness evaluation results after project completion show that the roof garden in the case plays an active role in improving the environmental efficiency, such as building energy conservation, rainwater management, improving urban thermal environment and increasing urban biodiversity. |
