Research on Brick Schema Representation for Building Operation with Variable Refrigerant Flow Systems
针对Brick、Haystack两类建筑元数据标准暂未定义变制冷剂流量系统相关内容的问题，该研究扩展Brick Schema形成VRF模块并完成验证。该研究配套开发的模型与服务框架已应用于中国境内某建筑，可为不同区域提供便携性能耗分析。该VRF模块为建筑语义网中的VRF系统表达提供可行方案，可支撑楼宇管理自动化策略与规模化建筑运行的语义网应用。
Abstract:Building metadata is regarded as the signpost in organizing massive building data. The application of building metadata simplifies the creation of digital representations and provides portable data analytics. Typical metadata standards such as Brick and Haystack are used to describe the data of the building system. Brick uses standard ontologies to create building metadata. However, neither Haystack nor Brick has provided definitions about the Variable Refrigerant Flow (VRF) system so far. For years, both Brick and Haystack working groups have been discussing how to describe VRF in their schema, mainly about the classification of VRF and the definitions of VRF units. There were no settled solutions for these problems. Meanwhile, the global VRF market is growing increasingly fast because of the energy efficiency and installation simplicity of the VRF system. It is needed to have the metadata to describe VRF units in buildings for data analysis and management. Addressing this challenge, this paper extended Brick Schema with the VRF module and verified the Brick VRF module. Then, the model and the service framework were developed and applied for a building in China. The framework can serve portable energy analysis for different areas. The VRF module of this paper provides a possible solution for the expression of the VRF system in the building semantic web. The works in this paper will support semantic web in automation strategies for building management and scalable building operation. 摘要：建筑元数据被视为组织海量建筑数据的指引。建筑元数据的应用简化了数字化表征的创建，并提供可移植的数据分析。Brick 和 Haystack 等典型元数据标准用于描述建筑系统的数据。Brick 使用标准本体创建建筑元数据。然而，迄今为止，Haystack 和 Brick 均未提供有关变制冷剂流量（Variable Refrigerant Flow，VRF）系统的定义。多年来，Brick 和 Haystack 工作组一直在讨论如何在其模式中描述 VRF，主要集中在 VRF 的分类和 VRF 机组的定义上。这些问题一直没有确定的解决方案。同时，由于 VRF 系统具备高能效且安装简便，全球 VRF 市场正日益快速增长。需要使用元数据描述建筑中的 VRF 机组，以进行数据分析和管理。为应对这一挑战，本文通过 VRF 模块扩展了 Brick Schema，并对 Brick VRF 模块进行了验证。随后，开发了模型与服务框架，并将其应用于中国的一栋建筑。该框架可为不同区域提供可移植的能源分析。本文的 VRF 模块为建筑语义网中 VRF 系统的表达提供了一种可能的解决方案。本文工作将为建筑管理和可扩展建筑运营自动化策略中的语义网提供支撑。
