【摘要】 依据美国开发的BEES软件,选择张家港当地某一栋具体的多层住宅建筑(6层,每层大约750 m2)进行了生命周期评价。把建筑的全生命周期范围确定为建材准备阶段(包括原材料开采、运输、原材料加工等)、建造阶段、运行阶段(运行70年)、拆毁阶段和建筑垃圾处理阶段。依据确定的范围进行了清单分析。根据建筑的结构形式,计算得到各种建材的需求量和建造、运行、拆毁、建筑垃圾处理时的各种输入输出,以统一的功能单位(一栋建筑)合并各种输入输出数据,得到总的数据清单。采用BEES分类表征方法进行影响评价。根据我国的具体情况确定环境影响因子和类别(酸雨、全球变暖、资源枯竭等),将不同的环境影响因子分配到一个或多个环境影响类别中,再根据具体情况确定各指标的权重系数进行加权,得到综合的评价结果。找出了建筑物全生命周期阶段中产生环境影响最大的阶段,即运行阶段。更多还原

【Abstract】 BEES that was developed in USA were selected to study a residential building in Suzhou.The boundary of the study included the preparation phase of building materials,construction phase,operation phase,the demolition phase and the waste disposal stage.According to the building’s structure,the demands of a variety of building materials were calculated and the input and output in every stage of the building life cycle were found and the inventory data of the building with a function unit were integrated.The impact assessment was carried out using BEES,with our own conditions.The result shows that the operation phase causes the biggest environmental impact in different life-span of the building.更多还原
