AOP alignment

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.

Sequence

  1. Done: 9.6.0 - Completed, on master.
  2. Done: 24.2.0 without auto-sizing (watch changes to CMake list). Make this a priority.
  3. 24.2.0 with auto-sizing.

Current build has most auto-sizing code, but variables are not yet exposed in modelDescription.xml.

Kyle will send a separate build.

Michael to add the following parameters at design conditions.

  • wind speed
  • wind direction
  • room temperature set point

The DesignSpecification:OutdoorAir specifies how much outdoor air need to be delivered for each zone and the system.

Michael to look into whether string parameters are supported in FMI.

Update: It is supported through fmi2GetString.

OpenStudio integration

To be discussed next time for AOP 25 planning and current milestones. David Goldwasser works with Amir on AOP, high priority for FY25.

Modelon

No discussions.

Compiler integration

No discussions.

FMI-QSS

Michael to meet Stuart tomorrow to talk about benchmarks.

Modelica Buildings Library

Backlog on fixing various issue.

PNNL priority is zone side templates.

PNNL has milestones for end of FY to implement heat pump water heater, mostly using existing classes. PNNL to make verification of heat pump water heater. PNNL to have internal review next week.

ORNL has dehumidifier as deliverable end of October, https://github.com/lbl-srg/modelica-buildings/pull/3475

Dehumidifer depends on thermal wheel, https://github.com/lbl-srg/modelica-buildings/pull/3554

ORNL works on autotuning PID, waiting for Jianjun's comment, https://github.com/lbl-srg/modelica-buildings/pull/2957

Work on air filter model is ongoing (to support multiple contaminants), https://github.com/lbl-srg/modelica-buildings/pull/3676

EnergyPlus-Modelica coupling

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

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.

Other items

None.

New action items

Focus on finishing pending PRs.

Michael to make issue on github to list spawn binary versions (version, hash etc.).

Previous action items

Think about priorities for FY25.
