“…The purpose of co-simulation is to allow each engine to simulate, in detail, those aspects of the model that they are best suited to represent. The proposed co-simulation capability couples a recent version of EnergyPlus [27] with the newly developed BEEAM Modelica library [26]. EnergyPlus can model most aspects of whole-building energy performance, such as heat gains from building loads, heat transfer, and HVAC system performance.…”

“…The components of the proposed electrical distribution system were modeled using the BEEAM library, which was developed by several contributing authors [26]. The BEEAM models electrical distribution systems in buildings, including conventional alternating current (AC), direct current (DC), and hybrid systems.…”

“…In this article, we describe an advance in co-simulation capability that combines the existing strengths of EnergyPlus ® [24] for whole-building energy simulations with the Building Electrical Efficiency Analysis Model (BEEAM), a newly developed Modelica library for the harmonic power-flow simulation of building electrical distribution systems [25,26]. The co-simulation capability leverages the FMI standard and is compatible with any Modelicabased co-simulation workflow.…”

This article describes recent co-simulation advances for the simultaneous modeling of detailed building electrical distribution systems and whole-building energy performance. The co-simulation architecture combines the EnergyPlus® engine for whole-building energy modeling with a new Modelica library for building an electrical distribution system model that is based on harmonic power flow. This new library allows for a higher-fidelity modeling of electrical power flows and losses within buildings than is available with current building electrical modeling software. We demonstrate the feasibility of the architecture by modeling a simple, two-zone thermal chamber with internal power electronics converters and resistive loads, and we validate the model using experimental data. The proposed co-simulation capability significantly expands the capabilities of building electrical distribution system models in the context of whole-building energy modeling, thus enabling more complex analyses than would have been possible with individual building performance simulation tools that are used to date.
