This tool quickens the run of EnergyPlus. EnergyPlus is a whole building energy simulation program that engineers, architects, and researchers use to model energy and water use in buildings. EPparallel splits a single annual EnergyPlus simulation into 12 simulations, runs them in parallel over a cluster of 12 nodes, and collates the results once the simulations are finished. It uses Message Passing Interface API and runs on Linux. It is based on the earlier studies done on the methodology for speeding EnergyPlus simulation by splitting an annual EnergyPlus simulation into multiple smaller simulations.

How to use the tool

• You need to have a 12 computer linux cluster to run this tool.
• Each system needs to have MPICH2, Network File System (NFS) and EnergyPlus version 6
• Code needs to be present on all systems. The C file energy12s1w7.c needs to compiled on all systems.
• To run the tool run the command 'epparallel IDFfilenamewithoutextension weatherfilenamewithoutextension'
