The Modelica Buildings Library 9.1.0 was released on December 06, 2022.

Version 9.1.0 is backward compatible with 9.0.0.

The library has been tested with Dymola 2023x, OpenModelica 1.20.0-dev (314-g3033f43-1), OPTIMICA (revision 2022-05-09-master-4b0cd2bf71) and recent versions of Impact.

The following major changes have been done:

  • The ASHRAE Guideline 36 air-side sequences have been updated to the official release. They are in the package Buildings.Controls.OBC.ASHRAE.G36. The previous public release draft is still distributed with this version.
  • Various new blocks for the Control Description Language have been added to the package Buildings.Controls.OBC.CDL.
  • The flow rate control in various examples has been improved to avoid large pump or fan heads if the mass flow rate is prescribed rather than computed based on the pump or fan curve.
  • Various models have been improved for robustness, for compatibility with the Modelica.Media library, and to correct errors.

For a detailed list of changes, see the release notes.
