[esp-r] release of ESP-r version 11.9

[Ian Beausoleil-Morrison]

ESP-r users and developers,

 

Version 11.9 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/getting.html.

 

Once you have installed the Subversion client you can download the source
code for version 11.9 of ESP-r anonymously using the following command:

      svn checkout https://espr.svn.cvsdude.com/esp-r/trunk

 

If you already downloaded the source code of a previous version with the
above command, then you do not have to do a full download of version 11.9.
Rather, you can update the source code by executing the following command
from your "trunk" directory:

      svn update

 

(ESP-r developers who wish to make source code contributions to ESP-r should
contact Bart Lomanowski at Bartosz.Lomanowski at nrcan.gc.ca who can configure
an account for you on ESP-r Central.  Further information on ESP-r Central
for developers is available at
http://www.esru.strath.ac.uk/Programs/ESP-r_central.htm.)

 

ESP-r source code is available exclusively through ESP-r Central.  However,
you can obtain pre-compiled versions for specific operating environments on
ESRU's web site.  These pre-compiled 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

11.9 (June 2010)

================

 

Simulator

---------

- A 1-node plant component model of an air-source heat pump has been added.

  The model incorporates optional outside air temperature compensation for
the

  flow temperature set point and optional defrost calculations.

  The model is described in:

    Kelly N J, Cockroft J, Gauri S, "Performance Analysis of Air Source Heat
Pumps

    Using Detailed Simulations and Comparison to Field Trial Data", Paper
submitted

    to The Biennial Conference of IBPSA-Canada, eSim2010, Winnipeg, Canada,
May 19-20.

 

 

Project Manager

---------------

- Further enhancements have been made to the GTK version.

- Integrated Performance Views can now be generated for models up to 72
zones.

- Constructions can now use to up 12 layers.

- The construction materials database has been cleaned up and materials
specified

  in the IBO PassivHaus book have been added.

- The EPW climate import facility has been updated to support files that
match the

  specific format of climate files purchased from CIBSE as well as newer
additions

  to the US DOE climate sets.

- There was a bug in drawing zones which had been defined via the
click-on-bitmap

  facility: this has been fixed.

- Occupant casual gains defined on a floor-area basis were subject to
rounding

  errors in reporting graphs and tables: this has been addressed.

- The drawing of the site origin has been improved for small and large
models.

- Occupancy pattern files and documentation for Korean standard occupancy,
lighting,

  and equipment patterns for 30 room types have been added. (Contributed by

  DASS Korea.)

 

 

Results Analyzer

----------------

- A new facility has been added that allows measured data (e.g. room dry
bulb 

  temperatures) to be associated with a model as an item in a temporal file.

  This allows users to display predicted and measured data simultaneously.

- By convention, a demand imposed on a battery is assigned a positive value
if

  the battery is discharging and a negative value if the battery is
charging.

  The current and power draws reported by the battery model in the power
flow

  domain now follow this convention.

 

 

Validation/Compliance Checking

------------------------------

- The logic, databases, and documentation associated with UK code

  compliance have been updated based on feedback from the accrediting board.

 

 

General

-------

- The export of ESP-r models to the TSBI3 tool is no longer supported. (This

  tool no longer exists.)

- Further support has been added for the alternate 'META file' model
description

  format.

- Database references have been made to improve model portability between

  computers.

- The support of graphics functions on some 64-bit computing environments
has

  been improved.

 

 

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.
