ISO 15686-5-2017 建筑物和建筑资产--使用年限规划--第5部分：生命周期成本计算 Buildings and constructed assets — Service life planning — Part 5: Life-cycle costing

This document 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.nd edition 2017-07 Buildings and constructed assets — Service life planning — Part 5: Life-cycle costing Batiments et biens immobiliers construits — Prévision de la durée de vie — Partie 5: Approche en co？t global Reference number ISO 15686-5:2017(E) ？ ISO 2017 ISO 15686-5:2017(E) COPYRIGHT PROTECTED DOCUMENT ？ ISO 2017, Published in Switzerland All
