住宅类绿色建筑项目的用地和规划指标性能分析

INDEX PERFORMANCE ON LAND USE AND PLANNING OF DWELLING PROJECTS WITH GREEN BUILDING LABEL

基于中国城市科学研究会2009～2010年组织评审的32个住宅类绿色建筑项目,统计和分析了《绿色建筑评价标准》涉及的人均居住用地指标、住区绿地率、人均公共绿地面积、室外透水地面面积比、地下建筑与建筑占地面积比5个"节地与室外环境"类指标以及户均面积、容积率、建筑密度3个常见指标,并重点对《绿色建筑评价标准》第4.1.3条人均居住用地指标如何修订进行了情景分析。最后,分别就相关指标的标准化计算方法、别墅和大户型住宅的指标性能、绿色建筑的定量化评价和分级作了讨论。

Based on 32 dwelling projects with Green Building Label(GBL) evaluated by Chinese Society for Urban Studies(CSUS) from the year of 2009 to 2010,five indices on land-saving and outdoor environment in Evaluation Standard for Green Building,namely residential land per capita,green space ratio,capita public green space,outdoor permeable surface percentage,area ratio of underground space to building footprint,and three common indices,namely average area per unit,floor area ratio(FAR),building density,are figured out and analyzed.Furthermore,scenario analysis on revising Provision 4.1.3 of residential land per capita in the Evaluation Standard for Green Building,is conducted.At last,discussions on standardized calculation of relative indices,index performance of villa and luxury residency,and quantitive assessment and rating of green building,are proposed.
