[esp-r] release of ESP-r version 11.2

[Beausoleil-Morrison, Ian]

Dear ESP-r users and developers,

Version 11.2 of the ESP-r system is now available.  A summary of the
changes and new features included in this release is given at the bottom
of this e-mail.

The source code may be accessed via the ESP-r Central Subversion
repository.  To do this, you must first install a Subversion client on
your system.  Free clients are available at
http://subversion.tigris.org/project_packages.html.

Once you have installed the Subversion client you can download the
source code for version 11.2 of ESP-r anonymously using the following
command:
	svn checkout https://esp-r.net/espr/esp-r/trunk
	OR
	svn checkout http://esp-r.net/espr/esp-r/trunk

If you previously downloaded version 11.1 with the above command, then
you do not have to do a full download of version 11.2.  Rather, you can
update the source code with the following command:
	svn update https://esp-r.net/espr/esp-r/trunk
	OR
	svn update http://esp-r.net/espr/esp-r/trunk


(ESP-r developers who wish to make source code contributions to ESP-r
should contact me directly so that we can configure an account for you
on ESP-r Central.  Further information on ESP-r Central for developers
is available on the ESRU web site.)

ESP-r source code is available exclusively through ESP-r Central.
However, ESRU will continue to produce and post pre-compiled versions
for specific operating environments on its web site.  These binary
versions will generally be made available within a few days of a source
code release and will be announced to this e-mail list.  Release notes
will also continue to be posted on the ESRU web site.

Regards,
- Ian

Release Notes
11.2 (November 2006)
====================
Generic Code Update
-------------------
- ESP-r can now be compiled using the gcc4/gfortran compiler set that
  is shipped with many current Linux distributions.  However,
non-trivial
  numerical differences have been found between ESP-r compiled with
  gcc4/gfortran and ESP-r compiled with gcc3/g77.  Consequently
gcc4/gfortran
  builds should be considered beta for the time being.
- The 'Install' script has been redesigned to streamline the
installation
  process.  A number of redundant user prompts have been removed and
support
  for compilations 'out of the box' has been improved for Sun cc/f90 and
MINGW.
- The 'Readme' file has been re-written to reflect recent changes to the
  distribution and compilation of ESP-r, and to provide the user with
more
  information.
- The 'text-only' version of ESP-r was revived, allowing users to build
ESP-r
  on environments on which neither X11 nor GTK is available.


Simulator
---------
- The treatment for half-hour centred solar data (such as found in CWEC
  climate files) has been updated so that sub-hour simulations use the
  appropriate interpolation.  This affects only solar data.
- A small bug affecting insolation analysis has been corrected.
- A new plant component model of an adsorption storage unit has been
added
  and variants of existing plant components for water storage tanks,
  pumps, pipes, and a new controller have been created to support the
  modelling of adsorption storage systems.  Interested users are
referred
  to the M.A.Sc. thesis of Maria Mottillo, which is available in the
'related
  publications' section of the ESRU web site.
- A new plant component has been added for modelling solar thermal
  collectors.  Interested users are referred to a paper by Didier
Thevenard,
  Kamel Haddad, and Julia Purdy, which is available in the 'related
  publications' section of the ESRU web site.
- A new boundary condition type has been added to the building thermal
  domain to support the CEN 13791 standard.  A treatment has also been
added
  to support the CEN 13791 approach for modelling surface convection.
  (The CEN 13791 approach for treating solar absorption on the other
side of
  partitions will be added in a future release.)  Numerous interface
changes
  have been incorporated to allow users to impose the CEN 13791 standard
for
  testing/validating projects.


Project Manager
---------------
- ISO 6946 U-values are now reported.
- Simulation presets can now support the integration of hourly results.
- The logic for flow component multi-sensor controllers has been
reworked.
- Numerous changes have been made to improve program navigation and work
  flow.
- Additional contextual help has been added, e.g. reporting of energy
  balances, external pressure coefficients.
- There is increased use of GTK widgets to improve the operation of
ESP-r
  built with the GTK (versus the X11) libraries.
- The logic supporting optical property switching has been corrected and
  extended.
- Improvements have been made to QA reports.
- Improvements have been made to the viewing of CFD domains and the
feedback
  provided to the user.
- A number of exemplar models have been improved.
- A bug caused problems when running models which included both
pre-defined
  simulation periods and a CFD domain.  This has been repaired.
- A bug caused program crashes when a faulty zone fuzzy logic controller
  was specified.  This has been repaired.
- A facility has been added to allow the copying of
infiltration/ventilation
  and/or casual gains from other zones.  Data can also be scaled by
  zone volume or floor area.
- A bug related to the drawing of the site origin has been repaired.
- A new exemplar has been added with an abstract representation
  of a heated floor and a chilled ceiling.


Quality Control Utility
-----------------------
- A number of bugs were repaired in the regression tester.
- New functionality has been added to the regression tester to help
  diagnose differences between reference and test versions of ESP-r
  and to compare run-time differences.


Additional Changes
------------------
- Many additional changes have been made that are transparent to the
user.
  Information on these, as well as further details on all the
above-mentioned
  changes, can be found in ESP-r Central's change log by providing the
