Library 7.0.0, which is based on the Modelica IBPSA Library
(<a href="https://github.com/ibpsa/modelica">https://github.com/ibpsa/modelica</a>), and it released BuildingsPy
2.1.0 for scripting Modelica simulations and development.</p>
<p style="margin-top:0.13in;margin-bottom:0.13in;direction:ltr">The Modelica Buildings Library Version 7.0.0 is a major release
that contains various new packages, new models and improvements to

<p style="margin-top:0.13in;margin-bottom:0.13in;direction:ltr">The following major changes have been done:</p>
<ul>
        <li>
<p class="gmail-compact" style="margin-top:0.03in;margin-bottom:0.03in;direction:ltr">New packages have been added to model
        building controls and to support the creation of emulators that
        compare the performance of building control sequences in the
        Building Optimization Performance Tests framework <a href="https://github.com/ibpsa/project1-boptest">BOPTEST</a>.</p>
        </li><li>
<p class="gmail-compact" style="margin-top:0.03in;margin-bottom:0.03in;direction:ltr">Various new control blocks have been added

        </li><li>
<p class="gmail-compact" style="margin-top:0.03in;margin-bottom:0.03in;direction:ltr">Various new equipment models have been
        added, such as models of absorption chillers, CHP equipment and heat
        pumps.</p>
        </li><li>
<p class="gmail-compact" style="margin-top:0.03in;margin-bottom:0.03in;direction:ltr">The reduced order building models now also
        allow modeling air moisture and air contaminant balance.</p>
        </li><li>
<p class="gmail-compact" style="margin-top:0.03in;margin-bottom:0.03in;direction:ltr">A tutorial has been added to explain how to
        implement control sequences using the Control Description Language
        that is being developed in the <a href="https://obc.lbl.gov">OpenBuildingControl</a> project .</p>
        </li><li>
<p class="gmail-compact" style="margin-top:0.03in;margin-bottom:0.03in;direction:ltr">The icons of many components have been
        updated so that they visualize temperatures, flow rates or control
        signals while the simulation is running.</p>
        </li><li>
<p class="gmail-compact" style="margin-top:0.03in;margin-bottom:0.03in;direction:ltr">Results of the ANSI/ASHRAE Standard 14
        validation (BESTEST) are now integrated in the <a href="https://simulationresearch.lbl.gov/modelica/releases/v7.0.0/help/Buildings_ThermalZones_Detailed_Validation_BESTEST_UsersGuide.html">users' guide</a>.</p>
</li></ul>
<p class="gmail-first-paragraph" style="margin-top:0.13in;margin-bottom:0.13in;direction:ltr">The library has been tested with Dymola
2020x and 2021, JModelica (revision 14023), and OPTIMICA (revision
OCT-stable-r12473_JM-r14295).</p>
