- Bi-directional daylight calculations using radiosity for complex
fenestration

Update on User Interfaces?

A number of graphical user interfaces for EnergyPlus are under development.
Two (DesignBuilder, EPlusInterface) are currently available in development
(beta) versions while the third (E+IEQ) should be available in 2005. Watch
this web page (www.energyplus.gov/ep_interfaces.html ) for up-to-date
information on these and other interfaces.

A number of utilities and tools for creating, editing, and running input
files come with EnergyPlus, including IDF Editor, EP-Launch, IFCtoIDF, and
HVAC-Diagram (see www.energyplus.gov/ep_utilities.html ). Third party tools
for creating, editing, and displaying EnergyPlus input files are also
available, including DrawBDL, EcoTect, Green Building Studio, EzDrawPlus,
TSe+, and EzPlus-Parm.  See www.energyplus.gov/third_party_tools.html for
more information.

What's going on in V1.2.0?

      Will there be any considerable difference between version 1.2.0 and
1.1.1?

      Yes.... and no. There are a number of new features and bug fixes.

      How about IDF and IDD? Do they remain unchanged?

      There will be some changes in the IDD and reflected in IDFs.
      Particularly for any new features, there will be new objects.

      Is version 1.2.0 backward compatible? Can I run a v1.1.1 file in v
1.2.0?

      For the most part, the answer is yes. Some report variables have
      changed names. To be sure, you can execute the transition program
      that will "transition" IDFs from V1.1.1 to V1.2.0. You can also view
      the ObjectStatus spreadsheet in the root folder of the installed
      version. This file has detailed explanations of changes to the
      objects.
