Minutes

Spawn journal paper

Plan to have solid draft by end of year.

Modelon

OCT release expected later in January.

Compiler integration

Kyle to share spawn-ci repo for automating builds.

FMI-QSS

Works on damping of problems that are sensitive to mass flow rate. Issue 1412 (state select Tp) is numerically better, but does not reduce step count; errors are reduced by a factor of 3. Now tries to get results for multi-step for Monday's meeting.

Modelica Buildings Library

For end of FY23, release Spawn with only interaction being to actuators, schedules, output variables, and keep EnergyPlus HVAC system. Maybe add parameter in top-level building, and then verify that there is no room air model in Modelica. Likely HVAC all or nothing for whole idf. How would we integrate for example a chiller plant? Actuators and outputs are hooks similar to ExternalInterface or EMS.

PNNL shared HVAC systems to be modelled, will get back with review feedbacks from LBL.

For FY24, consider adding sizing information and send back to Modelica as parameters.

EnergyPlus-Modelica coupling

Update to EnergyPlus 22.2.0

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
