The U.S. Department of Energy (DOE) has issued a new version of the award-winning EnergyPlus building energy analysis simulation program. EnergyPlus models a building's heating, cooling, lighting, ventilating, water, and other energy flows so designers and engineers can test different system combinations before construction begins. Version 3.0—available for Windows, Linux, and Macintosh operating systems—includes several new features such as:

  • New datasets
  • Input syntax changes
  • Updated zone and ventilation controls and models
  • Enhanced cost calculations and economic reporting
  • Extended documentation and guides.

For users interested in retrofitting, DOE has also updated and extended the program’s capabilities for modeling existing building envelope, daylighting, and HVAC equipment and systems. See the EnergyPlus Web site to learn more about the new features or download EnergyPlus Version 3.0 at no cost.
