Branch issue1129_energyPlus_zone works for multiple buildings for JModelica, Dymola and OpenModelica. This has the FMI interface now. Models moved from Experimental to ThermalZones.
Issues are at https://github.com/lbl-srg/modelica-buildings/issues?q=is%3Aissue+is%3Aopen+label%3Aspawn
Next, work on
- Kyle to implement schedules and EMS actuators on EnergyPlus side (blocker).
- Michael to add validation for schedules and EMS actuators, https://github.com/lbl-srg/modelica-buildings/issues/1633
- Kyle to correct delayed output variable, https://github.com/lbl-srg/modelica-buildings/issues/1679
- Kyle to support unit declarations (blocker), https://github.com/lbl-srg/modelica-buildings/issues/1680
- Kyle to support reading zone air temperature, https://github.com/lbl-srg/modelica-buildings/issues/1681
- Kyle to make EnergyPlus ignore RunPeriod (currently Spawn just hangs), https://github.com/lbl-srg/modelica-buildings/issues/1678
- Michael/Milica to use thermal zones in larger model, https://github.com/lbl-srg/modelica-buildings/pull/1663
- Michael/Kun to implement example with single zone model, https://github.com/lbl-srg/modelica-buildings/issues/1582
- Kyle to trigger an error if condition 1 below is not satisfied (or we need to change the contract)
- Kyle to make an FMU that does not compress the files.
- Kyle to look into generating all outputs in the folder tmp-simulation-TwoIdenticalZones
- Kyle to look into numerical instability (walls may be initialized to wrong temperature). See for example Experimental/EnergyPlus/Examples/VAVReheatRefBldgSmallOffice/FloorOpenLoop or Experimental/EnergyPlus/Validation/OneZone and set the initial room temperature to 10 degC.
- Kyle and Michael to work out how to filter level of info/error/fatal errors. See code near
const size_t nCat = fmi2_import_get_log_categories_num(bui->fmu);* Kyle to create installer package for all three platforms.
- All zones in the idf file must have a zone model in Modelica. Otherwise the simulation stops with an error.
- If there is an HVAC system in the idf file, then EnergyPlus issues a warning, the EnergyPlus HVAC system is not simulated, but the coupled EnergyPlus/Modelica simulation proceeds.
- For the EnergyPlus envelope, either the CTF transfer function or the finite difference method can be used.

No discussions.
Next:
- Work on experiment specification.
No discussion.
Potential paths: Check diff to frozen library. Allow n models to be changed. Upgrade path to full OCT version (with access to cloud version in an integrated way).
Need to define the different use cases and work flows.
Use of python API makes protection much easier, is sufficient unless interactive mode is needed. Java API would be needed for interactive mode.
No discussion.
Jianjun to work on modelica-json parsing in Modelica rather than CDL mode.
Ongoing is dealing with replaceable models.
None.
See next steps under "Refactoring room air balance".
Michael to keep working with Modelon on making dp of pressure drop elements a state rather than p using stateSelect.
