EnergyPlus is written in C++, using many C++11 features. It runs as a console application on Windows, Mac, and Linux (tested on latest Ubuntu LTS). Details on running EnergyPlus are available in a separate document (Running EnergyPlus in Auxiliary Programs). The following files are needed to run EnergyPlus:
- EnergyPlus.exe (the executable file)
- Energy+.ini (described below)
- Energy+.idd (the input data dictionary file)
- In.idf (the input file)
- In.epw - optional (weather data file)
The input data dictionary and input data file have been discussed in the previous sections of this document.
For weather simulations, EnergyPlus accepts EnergyPlus weather files. The actual file name is in.epw.
The usual release for Windows platform also includes a dependence on a shared library, EnergyPlusAPI.dll (.so on Linux).
