I'm trying to run EnergyPlus in Matlab. I found mle+ but I could only find guides for the GUI.

Since I have to run many simulations with data previously calculated in a Matlab script, it could be easier to run E+ directly inside a loop statement.

I found out how to do in python (https://unmethours.com/question/22157...) but I couldn't find it in Matlab.

Thank you!

Do you want to run E+ and Matlab synchronous that mean at each timestep EnergyPlus exchange data with Matlab mutually? Or, you want to call E+ in Matlab?

For now, I just need to call E+ in Matlab. Could you make an example typing the code?

What if I want to exchange data?

You can use system or dos function to call RunEPlus.bat located in EnergyPlus directory. There are two ways rnning energyplus:

1. Runging RunEPlus.bat batch file

For example:
dos('D:\Your_EnergyPlus_installation_folder\RunEPlus.bat in(idf file name without idf extension) in(weather file without epw extension)')

system('D:\Your_EnergyPlus_installation_folder\RunEPlus.bat in(idf file name without idf extension) in(weather file without epw extension)')

2. Runing energyplus.exe

For example:

 system('C:\YOUR_ENERGYPLUS_INSTALLATION_FOLDER\EnergyPlus.exe -w weather_file.epw idf_file.idf')

where -w represents the weather file option. Without "-w" you only get a sizing run. Here are more details (https://github.com/NREL/EnergyPlus/bl...)

Hi, thanks for your answer but it's not working. I was successful typing this: system('C:\YOUR_ENERGYPLUS_INSTALLATION_FOLDER\EnergyPlus.exe -w weather_file.epw idf_file.idf') In my case: system('C:\EnergyPlusV8-5-0\EnergyPlus.exe -w SanFrancisco.epw Building1.idf')

where -w represents the weather file option. Without "-w" you only get a sizing run. Here are more details (https://github.com/NREL/EnergyPlus/bl...) Please change your answer.

Running RunEPlus.bat can also work,my previous answer can not work may be bcause the file path of RunEPlus.bat is error and weather file name includes file extension!

Perfect, thank you very much!

Hi, I have the same problem. The running enegyplus.exe in Matlab works for me. However, instead of pushing the simulate button, I need it to be done automatically. Could you please tell me if you know how to make that run automatically?
