Welcome to the EnergyPlus Model Maker - a free service developed by NREL and DOE to help make it easier to use and learn EnergyPlus. The web-based forms allow you to enter general information about the building you want to model. The application then automatically creates a complete EnergyPlus input file, runs an annual simulation, and then emails you the EnergyPlus input, output, DXF and other files along with an annual summary of the energy results.
