ISO 12006-2:2015定义了开发建筑环境分类系统的框架。它根据特定视图（例如，按形式或功能）以及定义支持，为一系列信息对象类确定一组推荐的分类表标题。它显示了每个表中分类的对象类作为一系列系统和子系统是如何相互关联的，例如在建筑信息模型中。 ISO 12006-2:2015没有提供完整的操作分类系统，也没有提供表格的内容，尽管它给出了示例。它旨在供开发和发布此类分类系统和表格的组织使用，这些分类系统和表格的细节可能会有所不同，以满足当地的需要。 然而，如果ISO 12006的这一部分应用于本地分类系统和表格的开发，则将促进它们之间的协调。 ISO 12006-2:2015适用于建筑工程的整个生命周期，包括简介、设计、文件编制、施工、运行和维护以及拆除。它适用于建筑和土木工程，包括相关工程服务和景观美化。

ISO 12006-2:2015 defines a framework for the development of built environment classification systems. It identifies a set of recommended classification table titles for a range of information object classes according to particular views, e.g. by form or function, supported by definitions. It shows how the object classes classified in each table are related, as a series of systems and sub-systems, e.g. in a building information model. ISO 12006-2:2015 does not provide a complete operational classification system, nor does it provide the content of the tables, though it does give examples. It is intended for use by organizations which develop and publish such classification systems and tables, which may vary in detail to suit local needs. However, if this part of ISO 12006 is applied in the development of local classification systems and tables, then harmonization between them will be facilitated. ISO 12006-2:2015 applies to the complete life cycle of construction works, including briefing, design, documentation, construction, operation and maintenance, and demolition. It applies to both building and civil engineering works, including associated engineering services and landscaping.
