Public Release

The U.S. Department of Energy (DOE) has released EnergyPlus version 8.2.0, the first release of EnergyPlus built on C++ source code. New feature highlights are listed below. For more information about EnergyPlus, please visit www.energyplus.gov.

This is Update 1 of EnergyPlus version 8.2.0 which includes important bug fixes, including a fix for incorrect data in tabular sqlite database outputs. A full list of addressed issues is included with the installer package.

Highlights of this release (V8.2.0)

Core Changes to EnergyPlus

  • Internal simulation engine code translated from FORTRAN to C++ to spur the evolution of EnergyPlus through improved interaction with a larger community through a more popular code base, and improved access to code libraries for performance and enhanced capabilities.
  • Language change initially caused a slightly slower codebase due to translation overhead, however several restructuring efforts in the code eventually led to EnergyPlus v8.2 being faster than v8.1 in many tests cases.
  • Development transitioned to GitHub, where the source code is to be made fully public in the spirit of the open source license.

General

  • Bug fixes throughout.

Building Envelope

  • Integrated slab calculation now allow improved simulation of ground heat transfer

HVAC, Plant and Refrigeration

  • Improved sizing algorithm for including fan heat in cooling coil calculations
  • Improved sizing input options for scaling autosized values
  • Additional plant load dispatch algorithms based on meeting component part-loading targets
  • New models for single-sided natural ventilation with multiple openings
  • New on/off fan option for unit heater and unit ventilator
  • New fault model for coil fouling
  • DOAS direct to zonal water-to-air heat pumps
  • Expanded support for table lookup for plant equipment performance
  • New zone air mass flow balance option (partially link HVAC flows with zone mixing and infiltration)

Utilities

  • Ice storage curve-fit tool

Platforms

  • Windows 7 & 8: 64-bit version (32-bit version also available)
  • Linux (Ubuntu 14.04 and compatible) 64 bit versions; (32-bit and RHEL-compatible versions may be available via Helpdesk)
  • Mac OSX 10.9 64 bit versions
  • EnergyPlus v8.2.0 has been tested on all of these platforms
