BS ISO 15686-5:2017提供了对建筑物和建造资产及其部件（无论是新的还是现有的）进行寿命周期成本（LCC）分析的要求和指南。注1:生命周期成本计算考虑了从收购到运营再到处置的成本或现金流，即相关成本（以及收入和外部性，如果包括在约定范围内）。注2:生命周期成本计算通常包括备选方案之间的比较，或投资组合、项目或组件层面的未来成本估算。生命周期成本计算是在约定的分析期内进行的，明确确定分析是仅针对已建资产的一部分还是整个生命周期。 交叉引用:ISO 6707-1:2014 ED4ISO指南73:2009 Ed 1ISO/TR 15686-11:2014 Ed 1AS/NZS 4536NS 3454:2013SIA 480-2016ISO 31000:2009 Ed 1ASTM E917-15ISO 14040:2006（R10）Ed 2ISO 15686-2:2012 Ed 2astm E1185-07e1ISO 21930:2017ISO 15686-1:2011 Ed 2ISO 14044:2006（R10）Ed 1ISO 21931-1:2010 Ed 1ISO 14001:2015ISO 15686-3:2002ISO 15686-8:200631010:2009购买本文件时提供的所有现行修订均包含在购买本文件中。

BS ISO 15686-5:2017 provides requirements and guidelines for performing life-cycle cost (LCC) analyses of buildings and constructed assets and their parts, whether new or existing.NOTE 1 Life-cycle costing takes into account cost or cash flows, i.e. relevant costs (and income and externalities if included in the agreed scope) arising from acquisition through operation to disposal.NOTE 2 Life-cycle costing typically includes a comparison between alternatives or an estimate of future costs at portfolio, project or component level. Life-cycle costing is performed over an agreed period of analysis, clearly identifying whether the analysis is for only part of or for the entire life cycle of the constructed asset.Cross References:ISO 6707-1:2014 ED4ISO GUIDE 73:2009 Ed 1ISO/TR 15686-11:2014 ED1AS/NZS 4536NS 3454:2013SIA 480-2016ISO 31000:2009 Ed 1ASTM E917 - 15ISO 14040:2006 (R10) Ed 2ISO 15686-2:2012 ED2ASTM E1185 - 07e1ISO 21930:2017ISO 15686-1:2011 Ed 2ISO 14044:2006 (R10) Ed 1ISO 21931-1:2010 Ed 1ISO 14001:2015ISO 15686-3:2002ISO 15686-8:2008 Ed 1ISO 15686-7:2017ISO 14064-1:2006 Ed 1ISO/IEC 31010:2009All current amendments available at time of purchase are included with the purchase of this document.
