EnergyPlus is a new building energy simulation program designed for modeling buildings with associated heating, cooling, lighting, ventilating, and other energy flows.
EnergyPlus builds on the most popular features and capabilities of BLAST and DOE-2 but includes many innovative simulation capabilities including time steps of less than an hour and modular systems simulation modules that are integrated with a heat balance-based zone simulation. Other planned simulation capabilities include solar thermal, multizone air flow, and electric power simulation including photovoltaic systems and fuel cells. EnergyPlus is a simulation engine which reads input and writes output as text files. EnergyPlus input and output data structures were designed to facilitate third party interface development. Most users will use graphical user interfaces to develop the input files when these tools become available.
