标准摘要
[中文适用范围]： 本文件提供了对建筑物和构筑物及其部分进行全寿命周期成本（LCC）分析的要求和指南，无论是新建还是现有建筑。 注1：全寿命周期成本考虑了成本或现金流，即从获取、运营到处置过程中产生的相关成本（以及如果包含在商定范围内，还包括收入和外部性）。 注2：全寿命周期成本通常包括对替代方案的比较，或对投资组合、项目或组件层面未来成本的估算。全寿命周期成本是在商定的分析期内进行的，并明确指出分析是针对建筑物全寿命周期的一部分还是整个全寿命周期。 [外文原描述]： 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.
