Testing and Validation

An important ongoing part of EnergyPlus development is testing using industry standard methods as major builds are completed. The goal is to make EnergyPlus as bug-free as possible. Three major types of tests are currently conducted:

  • Analytical tests:
    • HVAC tests, based on ASHRAE Research Project 865
    • Building fabric tests, based on ASHRAE Research Project 1052
  • Comparative tests:
    • ANSI/ASHRAE Standard 140-2011
    • International Energy Agency Solar Heating and Cooling Programme (IEA SHC) BESTest (Building Energy Simulation Test) methods not yet in Standard 140
    • EnergyPlus HVAC Component Comparative tests
    • EnergyPlus Global Heat Balance tests
  • Release and executable tests

The BESTest suites compare the results of multiple simulation programs for a series of load-related attributes. For more information on IEA SHC Task 34/Annex 43 (BESTest), visit the IEA Solar Heating and Cooling Programme website.

EnergyPlus testing reports are available for many of these test suites. As new releases are completed and as we conclude new tests, we will add the results to this page. Click on the links below to view the reports for EnergyPlus version 8.2.0.

Testing reports for previous versions of EnergyPlus are available below:
