Abstract

A virtual model that mathematically represents operational behaviors is essential for implementing the concepts of digital twins (DTs) and building information modeling (BIM) to achieve intelligent, optimal building operations. However, current research lacks an approach to reliably construct virtual models. This paper introduces a concept named virtual in-situ modeling (VIM), designed to comprehensively represent building behaviors. The VIM framework is based on five key aspects: modeling environments, model types, modeling sources, modeling approaches, and model fusion techniques. VIM bridges BIM and DT, enabling virtual modeling during the operational phase and enhancing both BIM-based DT and DT-enhanced BIM. Case studies conducted using real building operations demonstrate the effectiveness of VIM, achieving a highly accuracy (RMSE of 0.24 °C). Additionally, the VIM-assisted fault detection and diagnosis (FDD) provided early detection and diagnostic estimation, outperforming FDD without the virtual model. This paper highlights the potential of VIM for advanced building operations and maintenance.

数字孪生和 BIM 之间的虚拟原位建模，用于先进的楼宇运营和维护

数字孪生（DTs）和建筑信息建模（BIM）概念的实施，对于实现智能化、最优化的建筑运营而言，一个能以数学方式表达运营行为的虚拟模型至关重要。然而，目前的研究缺乏可靠构建虚拟模型的方法。本文介绍了一种名为 "虚拟原位建模"（VIM）的概念，旨在全面表现建筑行为。VIM 框架基于五个关键方面：建模环境、模型类型、建模来源、建模方法和模型融合技术。VIM 是 BIM 和 DT 的桥梁，可在运营阶段进行虚拟建模，并增强基于 BIM 的 DT 和 DT 增强型 BIM。使用真实建筑运行进行的案例研究证明了 VIM 的有效性，实现了高精度（RMSE 为 0.24 °C）。此外，VIM 辅助故障检测和诊断（FDD）提供了早期检测和诊断估算，其性能优于没有虚拟模型的 FDD。本文强调了 VIM 在先进楼宇运营和维护方面的潜力。
