[EnergyPlus_Support] Highlights of the 1.0.2 release

[Linda Lawrie <linda@xxxxxxxxxx>]

This will soon be available on the EnergyPlus web site
(www.energyplus.gov).

Additions in this release version
These items have been addressed with this
release:

1. Auto sizing of Plant equipment (Boiler, Electric Chiller, Cooling
Tower, Engine Driven Chillers)
2. Restriction for reveal on Triangular Windows, FullExterior (1.0.1)
have been removed
3. Ground Temperatures and Slab constructions have been redone (in the
Example Files) along the lines of the new Ground Temp Calc program
4. Ground Temp Calc program is included
5. User input of cooling and/or heating zone design air flow rates; mix
& match with calculated rates; subsequent sizing calcs work as if
user input were calculated.
6. Added simulation of a variable flow secondary loop and a constant flow
primary loop simulation using existing simulation structure. 
7. New input file example for each new feature.
8. Reflection of beam solar radiation from outside and inside window
reveal surfaces.
9. Faster ReadVars program (post processing)
10. Bi-directional Shading devices
11. Warmest Zone supply air set point strategy; new Node output
"System Node Setpoint Temp"
12. Water-to-water heat pumps
13. Current Detached Shading is also aka Fixed Detached Shading and added
Building Shading (which will move with respect to building origin for
"relative" coordinates)
14. Simple Ventilation (addition of simple ventilation--similar to what
was done in BLAST with the addition of infiltration type coefficients to
modify the flow rate based on temperature difference and wind 
speed)
15. Linux Version

Linux Version
With this version, we introduce a Linux version available
by separate download.  This will be compiled versions of the
EnergyPlus and ReadVarsESO programs.  While not extensively tested,
the Linux version has been run on the full test suite and is showing only
minor differences in most files.
Known problems
While every effort has been made to clean up all the
?defects? that have occurred during our testing, quite a few known (and
even more unknown) probably remain. In particular, all the ?known
problems? from the last release have been addressed.  If you are
super interested in what has been addressed, the 22 issues resolved in
this release are installed in the main EnergyPlus folder  tab
delimited file V1-0-2-ResolvedIssues.xls.  In the release of 1.0.1,
we noted the following issues.  All have been resolved.

1.      RESOLVED -- Reveals in windows should not also specify the Solar Distribution ?FullInteriorAndExterior? --  if it does the solar distribution will be reduced to FullExterior with a warning noted.  This has a very high priority to fix  so you can leave the specification there and note the warning message.

2.      

RESOLVED -- Ground Temperature calculation preprocess  at the last minute before release, we found some show-stopping deficiencies.  These will be corrected very soon.  In the meantime, using that option on the install will put a small ?notice.txt? file in your install structure.

3.      

RESOLVED -- Several of the Test Suite results (ASHRAE RP1052 Analytical Tests) are farther out of line than we would like  we have not tracked down all the causes yet.  They may be simple differences in some assumptions with the test suites or may point to problems in EnergyPlus.

4.      

RESOLVED -- Incorrectly defined surfaces (such as a floor which is upside down) can cause invalid radiant exchange calculations. This condition is reported with the following error message: 
View factors not complete. Probably bad surface descriptions in zone=<zonename>


Enjoy.
