Parametric analysis is often used for exploring design options and identifying the relationship between design parameters and performance. The jEPlus tool has been developed specifically for performing complex parametric analysis with EnergyPlus. It provides a GUI for defining design parameters, editing models, manage simulation runs, and collecting results. With the GUI, hundreds of thousands of simulation cases may be created in the matter of minutes.
