2021-08-20 12:24:57 -0500 | marked best answer | EnergyPlusToFMU error Hi, i am trying to creating an FMU using the EnergyPlusToFMU package. I have done that in the past successfully. This is the error I am getting at the moment.C:\fakepath\Capture.PNG As you can see, instead of using "\" in the command line, we are using the symbol "¥". We are using a Japanese computer with Japanese language. Do you think is this the problem? I successfully created an FMU on my laptop with the same EnergyPlusToFMU version (version 3.0.0) but using English language |

2021-06-04 12:10:05 -0500 | marked best answer | Mechanical Ventilation in Dymola and co-simulations I have modelled a mechanical ventilation system in Modelica. I want to perform co-simulation using EnergyPlus for the building. I will export EnergyPlus as FMU and run co-simulations using Dymola as the master controller. From my mechanical ventilation model, I want to send to FMU the supply and return air temperature from the mechanical ventilation to the zone. I am planning to use an ideal mechanical system in EnergyPlus and override the temperature values (supply and return). Is it the best approach? Or is it more accurate if I send to EnergyPlus the sensible and latent heat outputs from the mechanical system in the zone? |

One FMU is my EnergyPlus model, the second FMU is the control algorithm developed in Matlab.

2020-08-07 09:58:57 -0500 | marked best answer | FMI 1.0 and 2.0 Hi, My question is about FMI 1.0 and 2.0. I want to couple Modelica FMU with EnergyPlus FMU. I want to link the Modelica FMU with the EnergyPlus FMU using a master algorithm such as PyFMI. In this situation, how can I select which FMI version I will use? EnergyPlus is compatible with FMI 1.0 while Modelica with FMI2.0. Is there an option in Modelica to select FMI 1.0? Thank you in advance. |

2019-11-25 03:39:10 -0500 | marked best answer | Atrium in EnergyPlus Hi, I want to model an atrium for a 4 storey building. The atrium is located in the centre of the building and in each floor there are rooms and corridors. I 've read in other threads that good practice is to use the ZONECROSSMIXING object. The examples I found are using this object to "connect" two thermal zones. In my case, since I have a 4-storey building I will have 4 zones to connect and calculate the temperature stratification. Is it better to divide the atrium into 4 virtual horizontal zones and use the ZONECROSSMIXING object or to use the AIRFLOWNETWORK:MULTIZONE:COMPONENT:HORIZONTALOPENING ? Which of these two objects will give a better representation of the temperature stratification. I am aware that the answer to my problem will be to perform CFD but it is not applicable in this case since we want to control to openings of the atrium, at the top floor, based on the temperature. Thank you in advance. |

2019-01-28 07:30:14 -0500 | marked best answer | EnergyPlus Modelica co-simulations and sensitivity analysis I am wondering whether is possible to perform sensitivity analysis for co-simulations. Currently, I am using EnergyPlus to generate the FMU and importing it into Modelica to run the co-simulations. I would be interested in creating different idf files with JEPlus and create the FMUs automatically so I could run the co-simulations. Is it possible? Is there any other way to perform sensitivity analysis with co-simulations? I tried to look online for any paper/report but I couldn't find any. |
