Refactoring room air balance

Branch issue1129_energyPlus_zone now works for one building for JModelica, Dymola and OpenModelica.

Next, work on

have a permanent link to download the built binaries (once the other bug is fixed).

replace custom C function calls with calls to proper fmi2 functions (ongoing on branch issue1129_energyPlus_zone_fmiSignature which is based on issue1129_energyPlus_zone)

then implement control I/O.

Discussion: - Use of FMILibrary. - Modelica write json file and sends it as a string argument. - E+ determines value references. - E+ writes modelDescription.xml file to path that was in json file. - All zones must be in Modelica, otherwise EnergyPlus should issue an error. - Make a top-level element "model": { "zones": ...}

End of months milestone: Disseminate installer package for all three platforms.

EnergyPlus I/O variables

No activity until room model is finished.

Modelon subcontract

LBNL subcontract is done.

Coordinate NREL subcontract.

Add Python 3 support as Python 2.x is end of its lifetime.

Support NREL in compiling binaries from OpenStudio through Java API.

Ideally add binary from Modelon.

Note that PyFMI already works with Python 3.

FMI-QSS

[No discussion.]

Next is Objexx and Modelon to implement new specification from https://lbl-srg.github.io/soep/softwareArchitecture.html#jmodelica-integration

CI testing (funnel)

Test using funnel as the default diff tool in BuildingsPy.
Use funnel for cross comparison between dymola and jmodelica.
Work on experiment specification.

Optimica license protection

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.

JSON representation for OS front-end to Modelica

[No discussion.]

Jianjun to work on modelica-json parsing in Modelica rather than CDL mode.

Other items

None.
