摘要：

为了评定生态绿屋面的环境效益,提出生态绿屋面的形式分类比较方法,针对绿屋面生产、施工阶段全寿命周期评价(LCA)比较分析,尤其是栽培条件、规模形态以及经济效益等方面的测试与评价。同时采用热流计对建筑屋面的传热系数进行了现场实测与测量误差分析,得到比较结论。计算模型和实测数据结果对不同形式生态绿屋面设计应用选择有一定的参考价值。

Abstract: In order to evaluate the environmental benefit of ecological roofs, the authors proposed the method to classify the types of green roofs. Based on the LCA(life cycle assessment) theory, the method compared green roofs in construction and delivering stages, which especially tested and evaluated cultivation conditions, sizes, economic effectiveness. etc. Meanwhile the heat transfer coefficients were measured with heat flux meter in site and the errors are analyzed, orderly the conclusion was drawn by comparing those parameters. The computing model and the measured data are very useful for the designer to make right choice from the different forms of green roofs.

Keywords: LCA; ecological; green-roofs form; test; comparison research
