本文件描述了建筑围护结构调试过程，以实现性能良好、耐用且可维护的建筑围护结构。本文件包括程序、方法和文件要求，描述了调试过程在项目每个阶段对建筑围护结构的应用。这些项目阶段从预设计到业主入住和运营。本文件通篇将该过程称为建筑围护结构调试（BECx）。 本文件适用于新建建筑和改建建筑- 调试。本文件供业主、调试供应商、建筑开发商、业主代表、施工经理、建筑师、承包商和/或顾问等使用。其目的是确定并完成交付符合业主性能要求的建筑围护结构所需的任务和活动。项目要求由业主和/或调试供应商（CxP）确定。 本文件确定了进行建筑围护结构风险分析所需的步骤。该分析将产生定义BECx水平的任务，与业主对与建筑围护结构性能相关的风险的容忍度相称。 本文件涵盖的BECx工艺适用于单个组件、组件组合或整个外壳组件。例如，单个组件可以是窗、空气屏障或隔热层。组合组件包括窗、空气屏障和完整的传热系统（例如隔热和屋顶组件）。整个建筑围护结构组件将包括建筑围护结构的所有热量、空气和湿度控制层，位于建筑的所有六个侧面。 本文件描述了任何第三方顾问和/或建筑围护结构调试提供商（BECxP）记录其技术资格、独立性和BECx流程知识的要求，包括其教育、培训和经验。

This document describes a building enclosure commissioning process to achieve a well performing, durable and maintainable building enclosure. This document includes procedures, methods and documentation requirements describing the application of the commissioning process to a building enclosure at each phase of a project. These project phases span from predesign through owner occupancy and operation. This process is referred to throughout this document as building enclosure commissioning (BECx). This document applies to new building construction and building re-commissioning. This document is for use by an owner, commissioning provider, building developer, owner's representative, construction manager, architect, contractor, and/or consultant, etc. Its purpose is to determine and complete the required tasks and activities to deliver a building enclosure which meets the performance requirements of the owner. Requirements for the project are established by the owner and/or commissioning provider (CxP). This document identifies steps necessary to perform a building enclosure risk analysis. The analysis will result in tasks that define the level of BECx, commensurate with the owner's tolerance for risk associated with building enclosure performance. The BECx process covered by this document is applicable to an individual assembly, a combination of assemblies or a whole enclosure assembly. For example, an individual assembly can be the fenestration, the air barrier or the thermal insulation. A combination of assemblies would include the fenestration, the air barrier and the complete heat transfer system, (e.g. both the insulation and roof assembly). A whole building enclosure assembly would include all heat, air and moisture control layers of the building enclosure, on all six sides of the building. This document describes requirements for any third-party consultants and/or building enclosure commissioning providers (BECxP) to document their technical qualifications, independence and knowledge of the BECx process, including their education, training, and experience.
