Abstract

This paper presents an update about recent additions to the Modelica Buildings library. The Modelica Buildings library is a free open-source library with dynamic simulation models for building energy and control systems. The library contains models for air-based HVAC systems, chilled water plants, water-based heating systems, controls, room and envelope heat transfer, multizone airflow, including natural ventilation and contaminant transport, and electrical systems. The recent major additions that will be presented in this paper are a CFD model that is embedded in a thermal zone, a package for buildings to electrical grid integration, models for demand response simulation and data-driven models to predict the building load. The CFD model is an implementation of the Fast Fluid Dynamics code that allows three-dimensional CFD inside a thermal zone, coupled to building heat transfer, HVAC components and feedback control loops. The package for buildings to electrical grid integration includes models for loads, transformers, cables, batteries, PVs and wind turbines. The models can be configured for DC or AC systems with two or three phase balanced and unbalanced systems. They compute voltage, current, and active and reactive power based on the quasi-stationary assumption or using the dynamic phasorial representation. The models for demand response include a demand response client and data-driven models that predict the anticipated load of a building. This paper will explain these packages and present illustrative examples.
