A tool that runs EnergyPlus (and TRNSYS) for parametric studies: you define parameters such as insulation thickness, glazing type, building orientation or HVAC set-points, and jEPlus generates every combination, runs them in parallel and collects the results into one table for comparison. It suits energy-design optimisation and sensitivity checks. Written in Java; it requires EnergyPlus to be installed.
