Modelica is a promising open-source modelling language for simulation and derivative-based optimization of multi-zone buildings, including detailed pressure-driven flow networks and building controllers. Such Modelica models have however not yet been demonstrated for buildings with many zones and complex HVAC systems. This paper presents and provides implementation details of the simulation model of a 32-zones building model in Modelica, with pressure-driven flow networks and a building controller, demonstrating the potential of Modelica. The modelling approach and computational aspects are presented. Furthermore, the model is calibrated and verified using on-site measurement data, which shows that, for the presented case study, HVAC can be modelled with errors up to only a few percent, while larger errors are observed for the building envelope model. A detailed building description is provided as supplementary material.

Modelica是一种有前途的开源建模语言，可用于多区域建筑物的仿真和基于导数的优化，包括详细的压力驱动的流动网络和建筑物控制器。但是，尚未针对具有多个区域和复杂的HVAC系统的建筑物演示这种Modelica模型。本文介绍并提供了Modelica中具有32个区域的建筑模型的仿真模型的实现细节，该模型具有压力驱动的流动网络和建筑控制器，展示了Modelica的潜力。介绍了建模方法和计算方面。此外，该模型已通过现场测量数据进行了校准和验证，这表明，在本案例研究中，HVAC可以建模时误差高达百分之几，而对于建筑物围护结构模型则观察到较大的误差。提供详细的建筑物描述作为补充材料。
