1. Introduction

This user manual explains how to install and use EnergyPlusToFMU. EnergyPlusToFMU is a software package written in Python which allows users to export the building simulation program EnergyPlus version 8.0 or higher as a Functional Mock-up Unit (FMU) for co-simulation using the Functional Mock-up Interface (FMI) standard version 1.0 and version 2.0 . This FMU can then be imported into a variety of simulation programs that support the import of the Functional Mock-up Interface for co-simulation. This capability allows for instance to model the envelope of a building in EnergyPlus, export the model as an FMU, import and link the model with an HVAC system model developed in a system simulation tool such as the Modelica environment Dymola.
