Milestones

LBL AOP 9/30 (go/no-go): Release that can couple Modelica-based control to E+. OK to release in early 2021.

(https://github.com/lbl-srg/modelica-buildings/milestone/18)

LBL AOP 3/30: Implemented radiant slab coupling in Spawn.

LBL AOP 3/30: Release Buildings Library with radiant slab coupling.

LBL AOP 6/30 (go/no-go): Posted beta version of Spawn (jointly with NREL, Objexx and Modelon)

Modelon

Optimica license protection.

Start separate discussion for how to give developers access to Buildings library.

Compiler integration

Kyle works on JModelica integration, and once this works, swaps it against OCT.

FMI-QSS

No discussion, will have separate call this week.

EnergyPlus-Modelica coupling

Binary code freeze by April 2.

New blocker came up: https://github.com/lbl-srg/modelica-buildings/issues/2512 This shows that end-to-end testing is needed across all idf files distributed with EnergyPlus.

Release moved to July/August after test suited in https://github.com/lbl-srg/modelica-buildings/issues/2512#issuecomment-852418589 works for the "nonhandled errors". This will move the DOE milestone.

Release of Buildings Library 7.0.1 may proceed in June.

Issues are at https://github.com/lbl-srg/modelica-buildings/issues?q=is%3Aissue+is%3Aopen+label%3Aspawn

Next, work on

Spawn FMUs are not yet self contained, https://github.com/lbl-srg/modelica-buildings/issues/2054

[For FY21, Q2] Kyle to fix schedule: https://github.com/lbl-srg/modelica-buildings/issues/2000

(Kyle either fixes it, or proposes new wording for https://lbl-srg.github.io/soep/softwareArchitecture.html#sending-input-to-energyplus)

[For FY21, Q2] Kyle to look into numerical instability (walls may be initialized to wrong temperature). See for example Experimental/EnergyPlus/Examples/VAVReheatRefBldgSmallOffice/FloorOpenLoop. The temperature in the attic should not raise in the first hour. (Pending since Nov. 2019)

Remove warnings issued by EnergyPlus, https://github.com/lbl-srg/modelica-buildings/issues/2220

Support negative start time in EnergyPlus, https://github.com/lbl-srg/modelica-buildings/issues/1938

LBL AOP 9/30 (go/no-go): Release that can couple Modelica-based control to E+. OK to release in early 2021.
