EnergyPlus

EnergyPlus is a building energy simulation program for modeling building heating, cooling, lighting, ventilating, and other energy flows. While it is based on the most popular features and capabilities of BLAST and DOE-2, it includes many innovative simulation capabilities such as time steps of less than an hour, modular systems and plant integrated with heat balance-based zone simulation, multizone air flow, thermal comfort, and photovoltaic systems. EnergyPlus is a stand-alone simulation program without a 'user friendly' graphical interface. EnergyPlus reads input and writes output as text files.

Installing EnergyPlus Version 3.1.0

EnergyPlus is available for Windows 2000, XP, and Vista as well as Linux (installation instructions), and Macintosh (installation instructions). There is no charge to install and use EnergyPlus. You must register your copy of EnergyPlus in order to receive an email with the installation password. Follow these steps:

  1. Read the terms in the license agreement that you will also see during the installation process. If you agree with the terms, proceeed with step 2.

  2. Fill out the form below.

  3. When you press continue, you will be directed to a page where you can download the Windows, Windows resumable web installer, Linux, or Macintosh version of the EnergyPlus software.
    (NOTE: The 'Windows' version is a full download of all EnergyPlus programs, documentation, and utilities. The 'Windows resumable web' version is a small install program where you can select the options you want and only have those portions of the install downloaded. EnergyPlus still resides and run on the local computer. There is no functional difference between the Windows full install and Windows resumable web install versions. The Windows resumable web version can be better for people who have trouble downloading the single big file since Windows resumable download version downloads pieces rather than a single file. It also restarts where it left off if the connection is dropped. It requires an internet connection during installation.)

  4. An installation password will be sent via email within 24 hours.
    (NOTE: Make sure your email address is entered correctly or you will not receive the installation password. Your email address is only used to send your installation password and to notify you of new versions of EnergyPlus. Your contact information is used only for licensing and will not be used, given away or sold for any other purpose.)

  5. Install and run EnergyPlus from the downloaded file.

  6. Download Weather Data for use in running EnergyPlus Version 3.1.0 examples.

  7. Support information and options.

NOTE: If your connection times out during the download process do not fill out the registration form again, the database will not accept duplicate registrations. Please refer to your installation email for a link to the download page.
