[Ibpsausa] Modelica Buildings Library 12.0.0, 11.1.0 and 10.1.1, and BuildingsPy 5.2.0 released

[Michael Wetter]

The Modelica Buildings Library 12.0.0, 11.1.0 and 10.1.1 were released on
March 17, 2025.

The Modelica Buildings Library 12.0.0 is a major release. Version 11.1.0 is
a minor release with new models, version 10.1.1 is a maintenance release,
and both are backward compatible with 11.0.0 and 10.1.0, respectively. All
three versions contain various model improvements and versions 12.0.0 and
11.1.0 also include new models.

BuildingsPy 5.2.0 adds features for Continuous Integration testing of
Modelica libraries, for automation of Dymola simulations without a window
connection, and it contains various bug fixes.
The following major changes have been done for the Modelica Buildings
Library 12.0.0:

   - The EnergyPlus coupling has been updated to EnergyPlus 24.2.0, and the
   implementation that uses EnergyPlus 9.6.0 has been moved to the Obsolete
    package.
   - The package Buildings.Fluid.Geothermal.ZonedBorefields has been added
   that allows modeling geothermal borefields in which groups of boreholes are
   operated with different mass flow rates and inlet temperatures, for example
   to create a hot core and warm perimeter.
   - The template models for air-source heat pump and chiller plants have
   been updated to allow an optional side-stream water-to-water heat recovery
   heat pump, and to allow optional buffer tanks on the hot or cold side.
   Also, its control has been updated.
   - The control sequences in the package Buildings.DHC.ETS and
   Buildings.DHC.Plants have been updated to comply with ASHRAE Standard
   231P (Control Description Language).
   - For pumps, fans, valves and dampers, changed the model for the
   actuator position. The new implementation changes the actuator position at
   a constant speed defined by the rise time (fans and pumps) or the stroke
   time (valves and dampers) rather than a second order filter. This gives a
   more realistic response, and also simplifies the control loop tuning.

https://simulationresearch.lbl.gov/modelica/releases/v12.0.0/help/Buildings_UsersGuide_ReleaseNotes.html

The library has been tested with Dymola 2025x, OpenModelica 1.24.0,
OPTIMICA 1.55.11 and recent versions of Impact.
The following major changes have been done for the Modelica Buildings
Library 11.1.0:

A new package with heat pump models has been added. The models can be
operated in reversible mode to provide heating or cooling, and can be
configured to use various approaches to compute performance, such as data
tables or Carnot analogy.

Also, various minor model improvements and bug fixes have been implemented.

For a detailed list of changes, see
https://simulationresearch.lbl.gov/modelica/releases/v11.0.0/help/Buildings_UsersGuide_ReleaseNotes.html

The library has been tested with Dymola 2024x Refresh 1, OpenModelica
1.24.0, OPTIMICA 1.55.11 and recent versions of Impact.
The following major changes have been done for the Modelica Buildings
Library 10.1.1:

Models have been updated to improve performance, to ensure compliance with
the Modelica Language Standard and to correct model errors.

For a detailed list of changes, see
https://simulationresearch.lbl.gov/modelica/releases/v10.1.1/help/Buildings_UsersGuide_ReleaseNotes.html

The library has been tested with Dymola 2024x Refresh 1, OpenModelica
1.24.0, OPTIMICA 1.55.11 and recent versions of Impact.
The following changes have been done for BuildingsPy 5.2.0:

   - Updated pyfunnel requirement to version 1.0.2 to avoid a problem with
   regular expressions. (See
   https://github.com/lbl-srg/BuildingsPy/issues/594.)
   - In buildingspy/simulate/Dymola.py and in
   buildingspy/development/regressiontest.py, switched simulator from dymola
   to dmc unless a gui window is requested. (See
   https://github.com/lbl-srg/BuildingsPy/issues/590.)
   - In buildingspy/simulate/OpenModelica.py, added support for
   setNumberOfIntervals. (See
   https://github.com/lbl-srg/BuildingsPy/issues/585.)
   - In buildingspy/simulate/OpenModelica.py, changed loading of Modelica
   libraries. (See https://github.com/lbl-srg/BuildingsPy/issues/586.)
   - In buildingspy/simulate/base_simulator.py, corrected statement for
   error reporting. (See https://github.com/lbl-srg/BuildingsPy/issues/583.)
   - In buildingspy/development/merger.py, added a new comment format to
   allow excluding Modelica code for certain libraries. (See
   https://github.com/lbl-srg/BuildingsPy/issues/566.)
   - In buildingspy/development/regressiontest.py, add option to create
   reference results in batch mode. (See
   https://github.com/lbl-srg/BuildingsPy/issues/560.)
   - In buildingspy/development/regressiontest.py, add option to get the
   coverage rate, i.e., what percentage of examples are covered by regression
   tests. (See https://github.com/lbl-srg/BuildingsPy/issues/253.)
   - For Optimica regression tests, added check for Integers that are too
   large to be represented
   - In buildingspy/development/refactor.py, corrected moving images to
   avoid creating a directory if the target directory already exists. (See
   https://github.com/lbl-srg/BuildingsPy/pull/548.)
   - In buildingspy/development/validator.py, added method
   validateHyperlinks() that searches for broken hyperlinks. (See
   https://github.com/lbl-srg/BuildingsPy/issues/544.)
   - For Optimica regression tests, added check for connector to itself
   (See https://github.com/lbl-srg/BuildingsPy/issues/504.)
   - In buildingspy/development/refactor.py, updated writing the Modelica
   package.order file to avoid changing the UsersGuide order. (See
   https://github.com/lbl-srg/BuildingsPy/issues/541.)
