EnergyPlus 8.6.0
EnergyPlus 8.6.0
Windows packages for EnergyPlus 8.6.0 and prior had a vulnerability in the View3D binary that could expose users to a stack-based buffer overflow. Because of this, all Windows packages 8.6.0 and older have been purged and are no longer available. We apologize for any inconvenience.
The U.S. Department of Energy (DOE) has released EnergyPlus version 8.6.0. The focus of this release was predominantly on bug fixes and code robustness, though some priority new features did get implemented. The full changelog for this release cycle is listed below. For more information about EnergyPlus, please visit www.energyplus.net.

- Linux (Ubuntu 14.04 and compatible) 64 bit versions; (RHEL-compatible versions may be available via Helpdesk)
- Mac OSX 10.9 64 bit versions
- EnergyPlus v8.6.0 has been developed and tested on all of these platforms
