LBNL: By 9/30/24, released Modelica Buildings Library that gets autosizing data from EnergyPlus.
NREL: By 6/28/24, published release that includes auto-sizing.
LBNL: By 9/30/24, demonstrated OpenStudio workflow from Spawn.

Sizing

Draft specification at https://lbl-srg.github.io/soep/softwareArchitecture.html.

No discussions.

Compiler integration

No discussions.

FMI-QSS

Michael to organize separate meeting with Stuart and Modelon.

Modelica Buildings Library

Backlog on fixing various issue.

PNNL has milestones for end of FY for heat pump water heater. Karthik works on slides to discuss HP curve determination.

ORNL has dehumidifier as deliverable end of this month. ORNL works on autotuning PID, waiting for Jianjun's comment. Heat exchanger documentation has been updated. Work on air filter model is ongoing (to support multiple contaminants).

EnergyPlus-Modelica coupling

Spawn related PR at https://github.com/lbl-srg/modelica-buildings/projects/2

Update to EnergyPlus 24.1.0, after fixes of some spawn issues below.

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

Next, work on https://github.com/lbl-srg/modelica-buildings/projects/2

OS compatibility matrix is at https://github.com/NREL/OpenStudio/wiki/OpenStudio-SDK-Version-Compatibility-Matrix

Autosizing added variables except for the coincident loads, which is hold up because of a refactoring of exchanged variables, and then picked up again, tentatively with a first implementation in 2 weeks.
