[EnergyPlus_Support] EnergyPlus V1.3.0 Now Available
EnergyPlus Version 1.3.0 Now Available
The tenth major version of EnergyPlus (1.3.0) was
released on April 21, 2006 and is now available
in versions for both the Windows and Linux
operating systems. Download this newest release
at no cost from the EnergyPlus web site:
<http://www.energyplus.gov/>www.energyplus.gov.
What's New in Version 1.3.0?
A few of the new features in EnergyPlus V 1.3 are
listed belowsee
<http://www.energyplus.gov/features.html>www.energyplus.gov/features.html
for a complete list of new features added in this and previous versions:
* UFAD (Under Floor Air Distribution) room
air model for exterior zones is now available.
* Completely reworked airflow modelingthe
new AirflowNetwork model replaces both COMIS and
ADS and has the combined
capabilities. Calculation of infiltration,
ventilation, mixing and cross mixing moved to
system time step for future feature development
of hybrid (mixed mode) ventilation control.
Differences in results are usually minor.
* Outside air temperature is now varied as a
function of zone or surface height above
ground. Wind profile options can be set
separately for the weather station and the
building site. Includes new zone and surface
report variables for height dependent properties.
There will be differences in results,
particularly in files with Ventilation or Infiltration.
* Simple earth tube model for preconditioning
(heating/cooling) outside air.
* Tempering valve (3-way valve emulation) for
effective and safe use of stored thermal energy.
* Variable and constant speed headered pumps.
* Detailed ice storage.
* New Compact HVAC models for fan powered
VAV, fan coil, night cycle controls, outside air
heat recovery, supply air temperature reset,
chilled/hot water temperature reset, VAV supply
fan part-load options, VAV fan blow through or
draw through option, and zone supply and return plenums.
* Energy end-use subcategories are now user-definable.
* New report variable for Zone Operative
Temperature (Operative Temperature Control planned for V 1.4 in October).
And many other enhancements and significant speed improvements throughout.
Update on User Interfaces?
Several interfaces and utilities for EnergyPlus
are now available. EP-Quick creates an
EnergyPlus input file based on a broad range of
zone templates. EP-Quick was released in April
2005. E2AC is an interface in Portuguese and
English available since January 2005 (more
languages are planned). DesignBuilder, a graphic
user interface, was released in December
2005. EFEN is now available in beta version for
users to test. Green Building Studio can take an
existing CAD file and convert to an EnergyPlus
input file. Several other interfaces are under
development. Watch our web site
(<http://www.energyplus.gov/ep_interfaces.html>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, and
HVAC-Diagram (see
<http://www.energyplus.gov/ep_utilities.html>www.energyplus.gov/ep_utilities.html).
Third party tools for creating, editing, and
displaying EnergyPlus input files are also
available, including DrawBDL, EcoTect, ESP-r,
Green Building Studio, EzDrawPlus, IFCtoIDF,
TSe+, and EzPlus-Parm. See
<http://www.energyplus.gov/third_party_tools.html>www.energyplus.gov/third_party_tools.html
for more information.

What?s going on in V1.3.0?
Will there be any considerable difference between version 1.3.0 and 1.2.3?
Yes.... and no. There are a number of new features and bug fixes.
How about IDF and IDD? Do they remain unchanged?
There are some changes in the IDD that are
reflected in IDFs. Particularly for any new
features, there will be new objects.
Is version 1.3.0 backward compatible? Can I run a v1.2.3 file in v 1.3.0?
For the most part, the answer is yes. There are
many changes that require you to transition to
V1.3.0. EP-Launch will now check the selected
file (if there is a version object) and you can
launch the Transition program from the EP-Launch
?File? menu. 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.
This is particularly important for existing input
files with COMIS objects ? they are both
internally and externally transitioned but will
not be internally transitioned in the next
release. If you have both COMIS and ADS objects
in your input file ? please contact email support
(<mailto:EnergyPlus-Support@xxxxxxxx>EnergyPlus-Support@xxxxxxxx)
for assistance.
