- Open source license. For the first time, EnergyPlus is available under a true open-source license. Under this license, which is modeled after the Mozilla Public License (MPL), you may obtain EnergyPlus source code, modify it, combine it with other software that is licensed under different terms, distribute it, and re-license it. The license is "weak copyleft" in that it covers only EnergyPlus and its modifications going forward. Code that is combined with EnergyPlus is not affected. This license requires that you distribute the source code for EnergyPlus modifications and that you refer to the EnergyPlus component of your distribution as "a modified version of EnergyPlus vX." You may remove the "modified" designation by obtaining prior written permission from Berkeley Lab. As with any open source license, there is no fee.
