1.1 本指南涵盖了总结建筑相关项目经济影响的通用格式。 1.2 该指南为技术人员、分析师和研究人员提供了一种工具，用于以简明的格式向管理人员和非技术人员传达项目影响。 1.3 本指南中描述的通用格式要求描述项目的重要性、分析策略、数据和假设列表，以及项目影响的关键经济指标。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 本指南减少了沟通项目影响研究结果的时间和精力，并提高了衡量经济影响者与评估和解释经济影响者之间的沟通质量。 5.2 遵循指南向用户保证，项目的相关经济信息以编制人和用户都能理解的摘要格式包含。 5.3 由于《标准指南》为报告项目的经济影响提供了一种一致的方法，因此它有助于比较不同项目和不同时间的经济研究。 5.4 该指南侧重于建筑项目和建筑相关研究。它适用于政府和私人项目。虽然示例涉及建筑相关项目，但本指南也适用于非建筑相关项目。 5.5 本指南的建筑行业用户包括建筑业主和管理者、私营建筑公司、建筑和建筑行业行业协会的研究小组、公共部门建筑项目各方以及进行建筑施工的政府实验室- 相关研究。 5.6 使用指南总结使用实践的经济影响研究的结果 E917 （生命周期成本）， E964 （成本效益比和储蓄投资比）， E1057 （内部收益率和调整后的内部收益率）， E1074 （净收益和净节约）， E1121 （回报）， E1699 （价值工程/价值分析），以及 E1765 （多属性决策分析的层次分析法）。 5.7 将本指南与指南结合使用 E1369 总结涉及自然或人的经济影响研究结果- 不经常发生但具有重大后果的人为危险或两者兼有。 5.8 使用本指南总结仅影响初始成本、效益或节约的项目的影响，以及影响生命周期成本、效益或节约的项目的影响。 注1: 专门处理初始成本、效益或节约的项目示例包括设计修改或创新施工实践，这些修改或创新施工实践可以减少劳动力或材料成本、缩短施工工期或提高施工生产率，但未来的成本、效益或节约保持不变。 5.9 使用本指南总结影响编制摘要的组织内部各方的项目的影响，以及不仅影响编制摘要的组织，而且影响组织外部团体的项目的影响。 注2: 影响为内部的项目仅对应于编制总结的组织承担所有成本并从项目中获得所有利益或节约，或两者兼而有之的情况。示例包括但不限于使用创新施工实践或替代建筑材料、组件或系统，以降低建筑业主的初始成本或未来成本，或两者兼而有之。 注3: 具有公共部门组成部分的项目通常会产生超出编制总结的组织范围的影响。例如，但不限于政府实验室进行的与建筑相关的研究、旨在减轻自然或人为危害后果的项目，或两者兼而有之，可能造成附带损害的项目，以及影响交通模式的公路和桥梁建设。 5.10 在促进项目分析师和项目经理之间的沟通以及其他决策方面，本指南的使用不受限制- 制造商。然而，使用该指南的巨大好处可能来自其在大型机构中的应用，例如联邦机构，其中许多项目都在竞争资金，需要系统地展示可以跨项目和机构进行比较的结果，以有效分配稀缺资金。

1.1 This guide covers a generic format for summarizing the economic impacts of building-related projects. 1.2 The guide provides technical persons, analysts, and researchers a tool for communicating project impacts in a condensed format to management and non-technical persons. 1.3 The generic format described in this guide calls for a description of the significance of the project, the analysis strategy, a listing of data and assumptions, and a presentation of the key economic measures of project impact. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 This guide reduces the time and effort to communicate the findings of project impact studies and improves the quality of communication between those who measure economic impacts and those who evaluate and interpret them. 5.2 Following the guide assures the user that relevant economic information on the project is included in a summary format that is understandable to both the preparer and user. 5.3 Since the standard guide provides a consistent approach to reporting the economic impacts of projects, it facilitates the comparison of economic studies across projects and over time. 5.4 The guide focuses on projects in construction and building-related research. It applies to government as well as private projects. And while the examples treat building-related projects, the guide is applicable to non-building-related projects as well. 5.5 Building-sector users of this guide include building owners and managers, private-sector construction companies, research groups in building and construction industry trade associations, parties to public-sector construction projects, and government laboratories conducting building-related research. 5.6 Use the guide to summarize the results of economic impact studies that use Practices E917 (Life-Cycle Costs), E964 (Benefit-to-Cost and Savings-to-Investment Ratios), E1057 (Internal Rate of Return and Adjusted Internal Rate of Return), E1074 (Net Benefits and Net Savings), E1121 (Payback), E1699 (Value Engineering/Value Analysis), and E1765 (Analytical Hierarchy Process for Multiattribute Decision Analysis). 5.7 Use this guide in conjunction with Guide E1369 to summarize the results of economic impact studies involving natural or man-made hazards, or both, that occur infrequently but have significant consequences. 5.8 Use the guide to summarize the impacts of projects that affect exclusively initial costs, benefits, or savings, as well as projects that affect life-cycle costs, benefits, or savings. Note 1: Examples of projects dealing exclusively with initial costs, benefits, or savings include design modifications or innovative construction practices that reduce labor or material costs, reduce construction duration, or increase construction productivity, but leave future costs, benefits, or savings unchanged. 5.9 Use the guide to summarize the impacts of projects that affect parties that are internal to the organization preparing the summary as well as projects that affect not only the organization preparing the summary but also groups external to the organization. Note 2: Projects whose impacts are internal only correspond to situations where the organization preparing the summary bears all of the costs and receives all of the benefits or savings, or both, from the project. Examples include, but are not limited to, the use of innovative construction practices or alternative building materials, components, or systems that reduce initial costs or future costs, or both, to the building owner. Note 3: Projects with a public-sector component frequently have impacts that reach beyond the organization preparing the summary. Examples include, but are not limited to, building-related research conducted by government laboratories, projects aimed at mitigating the consequences of natural or man-made hazards, or both, that have the potential to cause collateral damage, and highway and bridge constructions that affect traffic patterns. 5.10 There is no limitation to the use of the guide in facilitating communication between project analysts and project managers and other decision-makers. Substantial benefits from using the guide, however, are likely to come from its application in a large institution, such as a federal agency, where many projects are competing for funding, and a systematic presentation of results that can be compared across projects and agencies is needed to allocate efficiently scarce funds.
